The present application is generally related to lighting systems. In particular, the present applications is directed to systems and methods for improving marketability and enhance brand recognition of a product by controlling the light in the display unit presenting the product.
Color is a powerful means of communication and plays an important part in our everyday lives. Color can sway thinking, change actions, and cause reactions. It can irritate or soothe your eyes, raise your blood pressure or suppress your appetite. Corporations have always used color as a source of brand recognition and advertising. For example, it is a well known fact that in the majority of cases blue light suppresses appetite while red light increases hunger. For this reason, rarely are food advertisements the color blue or do you see blue light in restaurants. A University of Loyola, Md. study concluded that color increases brand recognition by up to 80 percent. Another independent study conducted by the secretariat of the Seoul International Color Expo 2004 yielded results which demonstrate the power of color in marketing. According to the survey, 92.6% of respondents said that they put most importance on visual factors when purchasing products, and when asked to approximate the importance of color by percentage when buying products, 48% of the respondents said 50-70 percent while 36.7 percent said 70-100 percent. This means that as much as 84.7 percent of the total respondents think that color accounts for more than half among the various factors important for choosing products.
Color does not just merely enhance memory and recollection of a product, but it also can subtly and quickly affect the decision making processes. In fact, CCICOLOR—Institute for Color Research studies concluded that people make a subconscious judgment about a product within 90 seconds of initial viewing and that between 62% and 90% of that assessment is based on color alone. Further research by the Henley Centre suggests that 73% of purchasing decisions are now made in-store. These studies further highlight the use of color in catching people's attention and quickly conveying brand identity to them to result in more successful sales.
Color influences brand identity in a variety of ways. Consider the success Heinz EZ Squirt Blastin' Green ketchup has had in the marketplace. More than 10 million bottles were sold in the first seven months following its introduction, with Heinz factories working 24 hours a day, seven days a week to keep up with demand. The result: $23 million in sales attributable to Heinz green ketchup (the highest sales increase in the brand's history). All because of a simple color change. Apple brought color into a marketplace where color had not been seen before. By introducing the colorful iMacs, Apple was the first to say, “It doesn't have to be beige”. The iMacs reinvigorated a brand that had suffered $1.8 billion of losses in two years.
Different brands are recognized world wide for their corporate colors. For example, in soft drinks, the first brand associated with red is usually the Coca-Cola Company. Their branding is such a force in today's beverage market that red can almost be associated with Cola in general as several other major brands including Qibla and Tab among privately labeled grocery store brands all use red for advertising. In contrast to the Coca-Cola red is Pepsi who markets their brand in blue. The corporate colors of these two brands create distinction and uniqueness between their respective products.
The present solution described herein provides systems and methods to coordinate and control the lighting of areas of a display unit in a manner desired based on the type, brand and other characteristics of the product presented for display via the display unit. A lighting control system may control the characteristics of light emanating from one or more light sources to cause a reaction or visual effect from light reactive material of the product or display unit. In some cases, the lighting control system may control the characteristics of light emanating from one or more light sources based on signals from detectors, such as sensing any state or condition of the ambient environment.
In one aspect, the present invention is related to a method for improving marketability of a product by controlling a characteristic of light emanating from a light source to an area of a display unit for presenting the product. The method provides a lighting control system which controls a light source emanating light toward an area of a display unit for presenting one or more products. The products include a light reactive portion reactive to one or more predetermined characteristics of light emitted by the light source. The lighting control system is configured to implement one or more characteristics of light emanating from the light source to correspond to the predetermined characteristics of the light reactive portion of the products. The lighting control system requests the light source to emanate light having the established characteristics onto the light reactive portions of products which react to the established characteristics of the emanating light.
In one embodiment, a light reactive portion of the one or more products comprises the interior or the exterior surface of packaging. The surface may include a coating responsive to a predetermined wavelength characteristic of a light source. For example, the coating may be a photoluminescent material, which is responsive to an ultraviolet (UV) LED that may be used as a light source. Once the light source illuminates the coating, the coating absorbs the LED's light and in response emits a light of its own via fluorescence. The light emitted from the coating may be of any color pigment, as determined by the molecular properties of the coating material.
In another embodiment, a lighting control system establishes and is configured to implement one or more characteristics of the light to be emanated from the light source to change an appearance of the object illuminated to a different color, or a color having a different intensity. An example of this embodiment is a color rendering application in which red apples are stored in a refrigerator inside a supermarket. A lighting control system is configured such that a light source is instructed to illuminate the red apples with a light which makes the red apples appear more red than under a normal lighting. This will attract consumers' attention and improve marketability of the red apples displayed.
In another embodiment, the light reactive portion of the product includes a dye that is not visible at one or more wavelengths of light. For example, the product may include a blue emitting organic photoluminescent material which is blue until illuminated by a UV light source of sufficient energy. In response to UV light, the organic material emits a green light via the process of photoluminescence. In this example, an element of a display system may be designed with a surface that has a material which remains blue until it is illuminated by a UV light, and then the display element, in response to the absorbed UV light, turns green. The light reactive portion may include any type of marketing feature such as a logo of a product, a product related message, a brand name or a company name. In one embodiment, the message may be provided in blue lettering, and upon exposure to UV light the letters emit green light. The UV light source may be hidden from a viewer of the marketing feature.
In another aspect, the present invention is related to a method for improving marketability of products by controlling characteristics of lights emanating from light sources to areas of the display unit for presenting the products. The method provides a lighting control system to control one or more light sources to emanate light toward areas of a display unit for presenting one or more products. A first light source emanates light toward an area of the display unit for presenting a first product. A first detector detects presence of at least one unit of the first product in the first area of the display unit. In response to the detection, the lighting control system establishes one or more characteristics of light to emanate from the first light source to correspond to one or more predetermined characteristics of light identified for the first product. The lighting control system, in response to the detection, requests the first light source to emanate light having the established one or more characteristics.
In one embodiment, the lighting control system controls a plurality of light sources emanating light into a plurality of areas responsive to one or more detectors. For example, two sensors may be sensing the presence of two products in two given areas respectfully. Upon detecting a first product in an area, a lighting control system commands the light source associated with the first area to emanate light having predetermined characteristics for the first product. A second detector may also detect presence of products in the second area. The lighting control unit in response to the detector, commands the light source associated with a second area to emanate light having predetermined characteristics for the second product. In response to further detections by the first detector or second detector, the lighting control system again changes the characteristics of the light emanating from the light sources to their respective areas. In addition, the detector associated with the first area may sense the second product in the first area, and sends a signal to the lighting control system, which in response commands the light source to change the characteristics of the light emanating the first area to be based on the second product. In other embodiments, the lighting control system changes the characteristics of the light emanating from the light sources responsive to a detector sensing any type of information from the environment.

In some embodiments of an LED as light source 104, the LED is any light emitting device, comprising one or more light sources and capable of providing light to the products presented in an Area, such as Area 1105A in
In some other embodiments, the light source may create all of the basic colors, including variations there of by only selecting particular wavelengths, a process also known as binning For example, Philips Lumileds Lighting Company categorizes blue LEDs as emitting wavelengths between 460 nm and 490 nm (Ref. AB21—Luxeon Product Binning and Labeling). However, they separate this 30 nm difference in wavelengths into 6 different “bins” varying by 5 nm each. The light output of the LEDs throughout these different bins vary to the human eye even though they are all characterized as “blue” LEDs. For example, bin 1 which is 460-465 nm will appear a very deep blue; however, bin 6 which is 485-490 will appear a very bluish green which some people might describe as aqua.
In some embodiments, binning is not used to control color in LED systems. Any hue or color may be created by mixing a group of primary colors, such as, for example, red, green and blue. The ability of the light emitting devices to be controlled to the accuracy of 5 nm wavelength range allows them to create vibrant colors. In yet other embodiments, the varying an object's appearance of color pigments to human eye as the result of illumination using a specific spectral range of light is utilized. For example, an object of a yellow pigment will appear orange to a human eye orange when illuminated by purple light. In another example, a blue pigment will appear black to human eye when illuminated by orange light. In yet another example, an object of a red pigment, when illuminated by a red light will be perceived by human eye as a lot more red.
Commercial refrigeration units are utilized all over the world and branded on the outside in addition to the product within. The branding on the outside is utilized to attract customers who are not in viewable range of the inside of the cooler. The lighting system disclosed herein utilizes light of a configurable wavelength, i.e., color, to not only to attract customers to the refrigeration unit, but to reveal its contents inside. The system allows the seller or vendor to select a particular color of light for the interior of the case which will be additive to the branding of the contents on the inside. For example, a soda manufacturer could coat or label a product with a message that is enhanced under blue light. The enhancement of the message as well as the new light of the enclosure (as opposed to the usual cool white) will attract customers to the product. However, once the product is removed from the enclosure, the message enhanced under the blue light may fade, revealing a new message on the product that was subtractive under the blue light.
In other embodiments, a blue light is used to “activate” fluorescent dyes that are normally not visible in normal light. In this application, the system may be installed with a particular blue wavelength specified by the seller of the merchandise inside of the cooler. The seller may print their packaging (frozen food, bottles, cans etc.) with a dye which is activated by the blue light. When the enclosure lighting is powered on, the seller's message will be displayed vibrantly to the consumer. In another embodiment, illumination properties of the lighting system are configurable, comprising a red, green, and blue system, and are capable of digitally generating particular colors depending on the merchandise being sold. Another embodiment, includes active and passive areas, which are defined within the display unit depending upon the specific product displayed. In this embodiment, an area is defined passive if the wavelength of the light illuminating the product is configured independently from the product actually displayed in the enclosure. An area is also defined active if a product detected by the system is placed within, and the LCS in response generates a specific brand enhancing light based upon the detected product. Detector circuits may include a detector module operable in conjunction with the LCS to determine the presence of a specific product, in response to presence of the product detected, issue a series of commands to emit the light having characteristics desirable to the product detected.
The light sources 104 may be arranged, organized, positioned, located, orientated or placed to emanate light in any suitable or desired manner and direction towards areas 105 of the display unit 103 and/or products 116, or any portions thereof In some embodiments, a light source is oriented to direct light towards an entire area. In other embodiments, a light source is oriented to direct light towards a portion of an area. In one embodiment, a light source is oriented to direct light towards multiple areas. In another embodiment, a light source is oriented to direct light towards a set of one or more products. In some cases, the light source may be oriented to direct light towards a predetermined portion of a product, such as the middle, top or bottom portion of a product. In other cases, the light source may be oriented to direct light towards the first product in a set of products. In still further embodiments, multiple light sources may be oriented to direct lights towards the same product or area, or portion thereof
Light emanating from the light source is identified as 118 in the

The thicker lines, within the diagram, are marked S0, S1, and S2 and correspond to singlet electronic states, while the T1 line corresponds to a triplet electronic state. Triplet states are metastable states of the molecule whose radiative emission is phosphorescent, while the singlet state radiation is fluorescent. The distance between the ground S0 state and the excited states above corresponds to the difference in energy between the two states. Thinner lines in the states correspond to the vibrational levels. The electronic energy levels of excited triplet states are normally lower than the electronic energy levels of excited singlet states of the same molecule.
Full bolded arrows up in the diagram in
Dashed arrows on the diagram in
Thinner full arrows up, going from S1 state to S0 or to vibrational states slightly above S0, represent fluorescent radiative emission, where a photon of light is emitted as the transition from S1 to S0 occurs. The photon energy and wavelength associated with fluorescent emission are determined by the distance between the transitioned energy levels during the transitional displacement. The wavy arrows originating from the arrow lines associated with fluorescent emission represent the photons emitted for each of the fluorescent transitions.
Inter-system crossing, or inter-system non-radiative transition, occurs between the singlet and triplet states and requires an interaction leading to a change of an electronic spin. As a result of inter-system crossing, a phosphorescent radiative emission occurs, and it is a slower process than a fluorescent radiative emission. The thinner full arrows going up, from T1 electronic state line to S0 ground state or the vibrational levels slightly above S0, represent the phosphorescent radiative emission transitions. Wavy arrows from these lines represent the photons of light emitted as the result of the phosphorescent emission.

The lighting control system 175, sometimes referred to as lighting system, may include a plurality of network enabled devices, such as a network enabled UIM 109 communicating via a network 103 with one or more network enabled LCMs 106. As will be described in further detail below, each of these network enabled devices may have a network address for communicating with each other. Each of the network enabled UIMs 109 and LCMs 106A-106N may communicate via a wired and/or wireless network using any type and form of protocol. In some embodiments, the UIM and LCMs communicate over an Internet Protocol or Ethernet based network. In various embodiments, the lighting system 175 may be considered to include those lighting related devices in communication with each other to perform any of the functionality and operations described herein. As such, in some embodiments, the lighting system 175 includes the UIM 109 and one or more LCMs 106A-106N. In other embodiments, the lighting system 175 includes the UIM 109 and the LCM and any LED drivers 107A-107N and LEDs 104A-104N controlled and managed by the LCM and/or UIM.

In the lighting system 175, the UIM 109 provides various interfaces, such as analog or digital interfaces, that may be configured to perform tasks, such as any lighting related task described herein. The UIM 109 receives input from these interfaces that influences or controls output to the LCM 106, which in turn controls and drives the LED drivers 107 and LED source 104. A first UIM 109 may communicate via a network 103 with and manage a plurality of LCMs 106A-106N. In some embodiments, a plurality of UIMs 109A-109N may be used to communicate with and manage a plurality of LCMs 106A-106N. In other embodiments, a first UIM 109A and a second UIM 109B may both communicate with and/or manage the same LCM 106 or set of LCMs 106A-106N. In one embodiment, a UIM 106 may be used to communicate and manage a lighting group 176.
The UIM 109 may also provide status, feedback or any other information about the operation and performance of the lighting system 175, or any portion thereof, such as a specific LCM or LED driver. For example, the UIM may present a web page via the network 103 to a user to determine the status of various operational aspects of the lighting system 175. The UIM 106 may include any monitoring and/or logging agents to detect and capture any activity of the operations and performance of the lighting system 175, or any portion thereof. In one embodiment, the UIM 109 provides information on the status of the network 103 between the UIM and any LCMs 106. In another embodiment, the UIM 109 provides information on the status of an LCM 106.
The LCM 106 provides a mechanism and means to interface digital controls and logic to a typical or otherwise “dumb” LED fixture 104. The LCM 106 receives input, commands or instructions from the UIM 109 and/or CSP 120 with respect to controlling, managing, driving or otherwise directing the operation of the LED driver 107 and corresponding LED source 104. The LCM 106 provides any type and form of output to transmit signals to a corresponding LED driver 107.

In other embodiments, a first LCM 106B communicates with a first LED driver 107A and a second LED driver 107B. In yet another embodiment, a first LCM 106A and a second LCM 106B are both used to communicate with one or more LED drivers 107. In some cases, a second LCM 106B may be used concurrently with a first LCM 106A for communicating with an LED driver 107. In other cases, the second LCM 106 may used as backup or a redundant LCM to the first LCM 106A for communicating with one or more LED drivers 107.
The LED driver 107 may include any type of logic, function or operation for controlling the current and/or power delivered to an LED source 104. The LED driver 107 may include software, hardware or any combination of software and hardware. In various embodiments, the LED driver 107 functions as an electronically-controlled current source providing a predetermined amount of current to one or more attached LED lighting modules 104 in response to received control signals. In one embodiment, the LED driver 107 acts as or provides a constant current power supply configured to provide a set current value to the LEDs despite the input voltage to the luminaire. For example, an Advance Transformer LED driver 107 may take a 120 VAC input and provide a 350 mA constant current output whereas the current is controlled and the voltage is stepped down, a typical “buck” topology. In some cases, the LED driver 107 may “boost” voltages in the case where the input voltage is lower than the forward voltage of the LEDs to be powered. In one case, the LED driver 107 may be configured as a “buck-boost” whereas the input voltage may be stepped up or stepped down as required. In some embodiments, these LED Drivers 107 offer dimming via a “PWM” (pulse width modulated signal), or analog control voltages including 0 to 10V control voltages. In other cases, the LED driver 107 may pulse the power input to the LED source on and off in order to adjust the intensity of the LED source 104.
The LED driver 107 may include a voltage-controlled current source, a current-controlled current source, a power MOSFET (Metal Oxide Semiconductor Field Effect Transistor), power amplifiers, power transistors, or high-current op-amps as well as resistive, capacitive and switching elements. In some embodiments, the LED driver includes current-limiting circuit elements at its output, so that current levels in excess of an LED's maximum rated value may not be exceeded. The driver 107 may include one or more input ports, e.g., a signal-control receiving port and an override control port, and one or more output ports, e.g., one or multiple signal output ports, a driver status port, and one or more current sensing ports. The LED driver 107 may receive and send pulse-width modulated signals, e.g., square wave signals with variable duty cycle. The input ports of the LED driver 107 may include over-voltage protection and surge protection to prevent damage by transient electrical fluctuations at its input ports.
In some embodiments, the LED driver 107 may be an ASIC (Application Specific Integrated Circuit), or a commercially produced, off-the-shelf LED driver chip. The driver 107 may be packaged in a housing, as a separate element of the lighting system 175, or may be incorporated into another element of the network or lighting group, e.g. into an LCM 106A or into an LED lighting assembly 104A. As an ASIC or commercially-available driver chip, the driver may be incorporated onto a printed circuit board (PCB) for custom-design or original-equipment manufacturing circuit applications. The LED driver 107 may have an external power supply, which powers internal circuitry in the driver and provides a source of amperage for the attached LEDs 104. The external power supply may be dedicated to the LED driver or shared with another element in the lighting system, e.g., an LCM.
In one embodiment, a first LED driver 107 communicates with or controls a single LED source 104. In other embodiments, a first LED driver 107A communicates with or controls a plurality of LED sources 104A-104N. In other embodiments, a first LED driver 107A communicates with or controls a first LED source 104A while a second LED driver 107B communicates with or controls a plurality of LED sources 104B-104N.
Examples of commercially-available LED drivers include an ADM8845 series LED driver chip, providing up to 30 mA current and connections for six LEDs, or an AD8240 series chip which must be used with an external transistor to provide sufficient drive current. Both of these driver chips are available from Analog Devices, Incorporated of Norwood, Mass.

An example of a packaged LED driver includes an LEDD1 driver, available from Thorlabs of Newton, N.J., or a SmartDriver VDX driver, available from i2Systems of Morris, Conn.
The LED light source 104 may include any type and form of Lighting Emitting Diode (LED) based luminaire or luminaire source, such as an LED lighting assembly. In some embodiments, the LED 104 may comprise one or more semiconductor p-n junction light-emitting diodes. The LED assembly 104 may be constructed, designed or adapted to receive current from a LED driver 107 and direct the current across the one or more p-n junctions in forward bias. In various embodiments, the brightness or intensity of light output from a diode is substantially proportionally related to the amount of current flowing across the p-n junction. The LED source 104 may include resistors to limit current flow across the one or more diodes, and may include heat sinks in thermal contact with the diodes so as to dissipate from the diodes. Optical elements, such as lenses or diffusers may be placed over the LEDs to concentrate or disperse emitted light. Wavelength shifting methods, such as thin films containing organic fluorescent molecules or inorganic phosphorescent molecules, may be included with the diodes to absorb and re-emit radiation at wavelengths shifted from the LED's natural emission spectrum. The LED source 104 may include one or more diodes, each emitting radiation at distinct wavelengths, e.g. red, amber, green, and blue. In other embodiments, the LEDs may comprise organic light-emitting devices (OLEDs) or phosphorescent light-emitting devices (PHOLEDs) or a combination of LEDs, OLEDs and PHOLEDs. In some embodiments, the LEDs 104 within an assembly may be mounted on an electromechanically-moveable element, so that the direction of light output from the LED assembly may be controlled. In yet other embodiments, an LED driver 107 may be incorporated within the LED lighting assembly 104.

C. Methods of Controlling Lights Delivered to Products in Display
Referring now to
In more detail, at step 205, any type and form of lighting control system 175 may be deployed with any type and form of display unit 102 or otherwise in any environment. In one embodiment, the lighting control system 175 is installed and operated to control one or more lighting sources of a display unit having products with light reactive material. In another embodiment, the lighting control system 175 is installed and operated to control one or more lighting sources of a display unit having portions of the display unit with light reactive material. In other embodiments, the lighting control system 175 is installed and operated to control one or more lighting sources in any environment having light reactive material external to the product and/or display unit. In some embodiments, the lighting control system may be deployed remote to the product and/or display unit. For example, the lighting control system may operate on a computing device in a location remote to the display unit and communicate with the light sources 104 via a network 103. In another embodiment, the lighting control system 175 is deployed in the vicinity of the display unit but not attached to or connected to the display unit. For example, a lighting control system 175 may be deployed in a first or central location to control and manage light sources 104 for a plurality of display units in multiple locations.
By way of example, a lighting control system 175 deployed in step 205 may be a system inside a clothing store where a brand of clothing is displayed under a UV light in order to emphasize photoluminescent features of the logos on the clothing. A system may also be deployed to create a light show effects of water or a sea breeze when illuminating a brand of body wash products. In another example, the lighting control system 175 is deployed to illuminate fruits, vegetables or other products stored in a refrigerator in a supermarket.
The lighting control system 175 may be deployed to control light sources to cause a reaction in any type and form of light reactive material 114. In case where the light emanating from a light source illuminates a light reactive material that induces a response from the material, including a response inside of it, response on its surface, or a change in a perception to a viewer, the given material then is a light reactive material. In some embodiments, a light emanating from a light source and illuminating a vegetable stored inside a refrigerator may initiate a process of photosynthesis inside a vegetable, then the vegetable may be considered a light reactive material. In another embodiment, a light emanating from a light source and illuminating vegetables may have characteristics which kill the bacteria inside and on the surface of vegetables. The vegetable being illuminated is, in this case also, a light reactive material. In yet another embodiment, a light source is illuminating a product for the purpose of color rendering, which alters the perception of the color in the eye of the consumer due to the combination of the color of the illuminated object and the color of light illuminating the object, the object being illuminated is also a light reactive material.
At step 210, the lighting control system 175 may be configured or instructed by any means to establish or set the characteristics of the light emanating from the light source to correspond to the characteristics of light desired for the light reactive material. In some cases, the lighting control system 175 is configured dynamically during operation. In other embodiments, the lighting control system 175 is configured statically or between operations. In one embodiment, the lighting control system 175 may be configured via a configuration tool 110. In another embodiment, the lighting control system 175 may be configured via a command panel 110. In other embodiments, the lighting control system 175, such as via the UIM or LCM, may receive instructions via a network 103 to establish the characteristics of light emanating from the light source. In some embodiments, the lighting control system 175 sets or establishes the characteristics of light emanating from the light source responsive to information received from any one or more detectors 112, 180. In yet another embodiment, the lighting control system 175 is preconfigured or preset to emanate light have the desired characteristics corresponding to the light reactive material.
Via the configuration, the lighting control system may establish any parameters or settings representing the characteristics of light to emanate from the light source, such as color, wavelength, frequency, intensity, etc. Configuration or establishment of the lighting control system 175 may include the setting, calibration or adjustment of any type of parameters or settings via any type of interface, such as an application programming interface, graphical user interface or command line interface. Configuration may include issuing any commands or instructions. In some embodiments, configuration may include the use of any type and form of protocols, software programs, control scripts or any other type of instructions to control the characteristics of the emitted light tailored to the needs of the light reactive material. In one case, configuration may take place via a network connection to the lighting control system 175, such as via an Internet connection. Another way to configure the system may be using a blue tooth receiver to send commands or instructions to the lighting control system 175 from any type and form of mobile device. Furthermore, the system settings and configuration parameters may be stored in memory or storage of the lighting control system during installation. In some cases, one or more commands may be used to activate the stored configuration settings. The lighting control system may also be pre-configured by the factory at time of manufacture and/or prior to installation or shipment.
At step 215, the lighting control system 175 directs, requests or instructs the light source to emanate light having the configured or established characteristics desired for the light reactive material. Responsive to the establishment of the lighting characteristics at step 210, the lighting control system 175 directs the light sources to provide light in accordance with the desired characteristics for the light reactive material 114. In some embodiments, the lighting control system 175 turns on the light source 104. Upon powering up, the light source 204 may provide the light in accordance with the established characteristics. In other embodiments, the light source is already powered on and the lighting control system 175 changes or adjusts the characteristics of light emanating from the light source. In some embodiments, the lighting control system 175 is controlling multiple lights sources directed to the light reactive material 114. Responsive to the established light characteristics at step 215, the lighting control system 175 may direct one light source of the multiple light sources to emanate the established lighting characteristics towards the light reactive material. In another embodiment, the lighting control system 175 may direct all or more than one of the multiple light sources to emanate the established lighting characteristics towards the light reactive material.
In one embodiment, at step 215, since the system is configured to the settings desired for a given product or a display feature, the request is sent by the lighting control system for the light source to emanate light according to the established light characteristics. In one embodiment, this request may originate for the user sending the command via a remote control associated with the system. The lighting control system 175, such as via UIM, receives the request and sends the request to an LCM as depicted in
At step 220, the output of the light source is adjusted or changed, via the lighting control system 175, to emanate light having predetermined characteristics responsive to detectors, sensors, configuration, etc. While the system is in operation and the light is illuminating from the light source towards the area having light reactive material, requests may be issued via the lighting control system 175 to alter the characteristics of the light output. For example, a product may be changed in the area of the display 102, for example from one product to another product, such as red apples. In one embodiment, the lighting control system 175 may adjust the output of the light emanating towards an assortment of red apples replacing a previous product which required a different light illumination from that desired for the red apples. Upon placing the red apples into the area of the display unit 102, a detector or user may send a signal to the lighting control system 175 to change the light properties of the emanating light for the new product, such as a stronger red color component in order to use color rendering when displaying the red apples.
In another example, an enclosed refrigerator may display vegetables and fruits and have a door monitored by an interlock sensor. The refrigerator may include two separate light sources. The first light source may be a UV light source which illuminates vegetables with UV light, killing bacteria while the sensor monitoring the door is detecting the doors of the fridge to be closed. The second light source may be a white light source, turned on only when the doors of the refrigerator are opened. The light emitted inside the fridge is initially a UV light emitted from the first light source. When the user opens the door, the user triggers the sensor to send the request to the lighting control system 175 to switch the light source, which in turns sends the commands and instructions to the LCM and LED Driver to turn off the UV light source and turn on the second white light source. The user then has a clearer view of the refrigerator. However, once the doors are closed again, the sensor sends another command to the lighting control system 175 to turn of the white light source and resume UV light illumination of the products inside the fridge.
One embodiment that provides another example of method 200 described above includes a lighting control system 175 to control an array of lighting sources for emanating light having wavelength properties that promote photosynthesis in vegetables, such as vegetables stored in a refrigerator inside a store. In this example, the lighting control system 175 requires controls one or more light source to illuminate an area in the refrigerator displaying green vegetables using a white light in the presence of consumers in the vicinity of the refrigerator. In the absence of consumers near the refrigerator, the lighting control system 175 shifts the wavelength spectrum of the light emanating from the light source 104 to a spectrum with a dominating 590 nm wavelength in order to promote the process of photosynthesis within the leaves of the vegetables. The 590 nm wavelength dominated light helps the vegetables creating chlorophyll, making them look greener, and also helps the vegetables with the process of photosynthesis. The vegetables which are reacting to the 590 nm dominated light via the photosynthesis or the creation of chlorophyll, are the light reactive material in this example. The configuration of the lighting control system 175 may include establishment of two settings for the illumination of the vegetables. One setting is associated with white light illumination which is more presentable to the consumer, and the other setting is associated with a 590 nm light dominated illumination, which helps the vegetables with the process of creation or activation of chlorophyll and the process of photosynthesis.
While the store is closed or otherwise no customers are detected near the vicinity of the display unit 102, a detector 180 sends a signal to the lighting control system 175 that no movement is detected or otherwise an indication that there are no customers near the display unit. Upon receiving the request, the lighting control system 174 sends instructions to the LCM, which in response sends instructions to the LED Driver to emanate light from the LED 104. As the result, the light shifts to orange 590 nm wavelength dominated light, and the vegetables illuminated activate chlorophyll and maintain the process of photosynthesis. A detector 180 may sense the arrival of a customer near the vicinity of the display unit. The detector 180 then sends the request to the lighting control system 175, such as via network 104, which in response issues instructions to the LCM to turn off the 590 nm dominated light and turn on the white light. The 590 nm dominated light is turned off, and the white light is turned on.
Referring now to
In further detail, in step 305, a lighting control system 175 is provided to control one or more LED light sources to emanate light toward areas of a display unit for presenting one or more products. The lighting control system 175 may be in communication with one or more detectors 112, 180, such as via a network 103. Any type and form of one or more of the same or different detectors 112, 180 may be deployed. The detectors 112, 180 may be deployed in any portion of the display unit, interior or exterior. In other embodiments, the detectors 112, 180 may be deployed to predesignated areas of a display unit for products. In another embodiments, the detectors 112, 180 may be placed, located and/or oriented in a manner to obtain appropriate or suitable detection of a state or condition.
The lighting control system 175 may deployed in any type of environment and for a multitude of applications. For example, in one embodiment, a display unit may be set up inside a clothing store The lighting control system 175, either local or remote to the display unit, controls a plurality of lighting sources illuminating light towards a brand of clothing using a UV light in order to emphasize the brand logos on the clothing, The brand logos may include contains photoluminescent light reactive material. Another example may be a system to create a light show effect of water, fire, or a sea breeze when illuminating a brand of body wash products in a store window. In another example, the lighting control system controls light sources inside a fridge having vegetables or fruits. Other examples may include color rendering applications, involving a display unit with a lighting control system which controls the characteristics of the light illuminating the products presented via the display unit.
At step 310, one or more detectors may detect any state or condition of the environment, such as a state or condition of the products, or the ambient environment of the display unit or product. In yet other embodiments, the detector may detect any state or condition of an environment remote to the product or display unit, such as the temperature in a remote location. In one embodiment, one or more detectors may detect a state of presence, absence, movement, or quantity of products in an area of a display unit. In other embodiments, the detectors may detect a color or color temperature of a product. In some embodiments, the detector may determine via a bar code and/or RFID tag information about the product. An example of such instance could be a consumer approaching the shelf comprising products to be illuminated via a light show. Another example may be the sensor detecting the absence of products left in the shelf on the display such as via a weight or pressure sensor. Other embodiment may involve sensors detecting a user or object movement, a temperature, or sound from the area or the environment surrounding the system. Other examples may also include any system involving a sensor detection of any kind for the purpose of detecting a state of an area, or a state of any of the relevant parameters from the area or a surrounding environment. The detectors may communicate information in any format or via any protocol to the lighting control system 175.
At step 315, responsive to the detectors or information provided by the detectors, the lighting control system 175 adapts or establishes one or more characteristics of the light emanating from the light source to correspond to predetermined characteristics of light desired based on and responsive to the detection. One example of this method is configuring a light control system 175 to have settings specified and assign to each of the products which may be displayed in an area. The settings of the lighting control system 175 may be as such that the lighting control systems makes adjustments to the characteristics of the light emanating from the light sources in response to a signal from a detector. An example of this embodiments, is configuring the lighting control system 175 such that a first setting is used for a light having a first characteristics for a display of green vegetables and a second setting for a light having a second characteristic for display of red apples. The lighting control system 175 may change between two settings responsive to the detector sensing the tags associated with products. The lighting control system 175 may be configured in any way to have settings for light characteristics associated with each of the products, and the change of the settings being responsive to a signal from a detector. The lighting control system 175 may dynamically establish or change the characteristics of the light emanating from a light source based on any business rules and information received from one or more detectors.
In further details, at step 320, the lighting control system requests the light source to emanate the light having the characteristics desired based on the detection. In one embodiment, the lighting control system 175 makes the request immediately upon detection. In another embodiment, the lighting control system 175 makes the request upon a predetermined time after receiving the detection or otherwise a predetermined delay. In other embodiments, the lighting control system 175 makes the request upon receiving a second detection or upon other information received from any other detector. In yet one embodiment, the lighting control system 175 requests the light source to emanate the light having the characteristics desired based on signals or information from multiple detectors, such as detection of a predetermined product and a temperature. In some embodiments, the lighting control system 175 controls light from a single light source based on the detection. In other embodiments, the lighting control system 175 controls light from multiple light sources based on the detection.
In one example, a detector senses arrival of a customer at the display or into a store and sends a signal to the light control system. In response to the signal, the lighting control system 175 may adjust the lighting of the light source from one spectrum of lighting to another spectrum of lighting. In another example, the lighting control system may switch between white light to the UV light responsive to detection that the doors of a display unit are closed.
At step 325, the lighting control system 175 may continuously change or adapt the characteristics of the light emanating from the light source to one more predetermined characteristics responsive to the detector, control panel, information received via the network, etc. As the lighting control system receives signals from one or more detectors, the lighting control system dynamically adjusts the characteristics of the light emanating from the light sources based on and responsive to the detections. For example, as the ambient environment to the product or display unit changes, the lighting control system changes the characteristics of the light emanating from the light sources in response to the changes in the ambient environment. The lighting control system 175 may make adjustments to the light characteristics on a predetermined frequency based on the most recent detected information. In other embodiments, the lighting control system 175 may make adjustments to the light characteristics upon receipt of signals from a detector or receipt of signals from multiple detectors.
