Patent Application
20080265802
Lighting systems used in commercial entities such as retail shops, pleasure grounds, discotheques, and private households are able to create essentially any color or attractive atmosphere. Through the use of several lighting elements contained within a system, the system has the ability to emit different colors. The different colors are usually based on preset choices. Lighting systems can be combined to form unusual or eye-catching multiple system arrangements. In home environments, multiple system arrangements can be used and positioned in standard vertical or horizontal alignments, a combination of horizontal or vertical alignments, or arbitrary arrangements suitable for the household resident. In commercial entities, multiple system arrangements provide attractive, colored displaying options for products, and provide an attractive atmosphere, e.g. in combination with music in a discotheque.
In systems that have an ability to display multiple color offerings, a key problem is control of the color for each individual system. For example, if a shop manager desires to draw attention to shelved products located in front of one particular system, the shop manager will likely have to remove rows of product to adjust that system to the desired color. This problem is only exacerbated if the shop manager desires the different systems of the arrangement to each emit a different color, or the shop manager modifies the colors frequently. In a private household, the lighting system arrangement may be located at a height or distance not easily accessible by the resident, requiring the use of ladders and other implements to modify the colors of the system.
Pointing devices, such as remote control devices, allow for interface with a distant or not easily accessible object, providing the user a means of modifying the object while avoiding the difficulty and inefficiency of having to directly approach the object. Pointing devices and remote control devices utilize electromagnetic beams, such as beams of light, for interacting with the objects. Light receiving elements in the object are used for sensing the beam of light. Typically the beam of light is in the form of light pulses that are directly interpreted as control signals.
Pointing devices may also be utilized for controlling light panels in a similar way. In some cases, the pointing device may be utilized to select options displayed on the light panel. International Patent Publication WO 2005/029395 (“the '395 Publication”), incorporated herein by reference thereto as if set out in entirety, uses a coordinate detection system comprised of a light guiding layer in a light panel to sense and detect where a beam of light emanating from a pointing device strikes the light panel to facilitate option selection.
However, current technology fails to show means and methods for easily and efficiently controlling a lighting system having preset color offerings.
It is an object of the present system to overcome these and other disadvantages in the prior art.
The present system provides means and methods for easily and efficiently modifying the color of a lighting system. In accordance with the present system, a device for the wireless control of the color of light emitted by a lighting system is provided, wherein such device includes a signal generating means, a signal transmission means. The lighting system further includes a signal receiving means and a means for controlling the color of light emitted from the lighting elements.
In accordance with an embodiment of the present system, a device is provided for the wireless control of the color of light by a lighting system, such device includes a light panel having a predetermined number of emitted color options and a processor operably coupled to the light panel. The processor responds to a first color selection actuation by controlling the light panel to display each of the predetermined emitted light options within different portions of the light panel. Thereafter, the processor responds to a second color selection actuation by controlling the light panel to display a selected one of the predetermined emitted light options substantially over the light panel, wherein the selected one of the predetermined emitted light options is indicated by the second color selection actuation.
In accordance with another embodiment of the present system, a method is provided for modifying the color of a lighting system wirelessly, including directing a wireless device, activating the device, transmitting a beam of light from the device to a lighting system, manipulating the device through movement in order to direct the beam of light position on the lighting system, and changing the color of the lighting system by pressing a button on the device.
In accordance with a further embodiment of the present system, a method is provided for modifying the color of a lighting system wirelessly comprising directing a wireless device, activating said device, transmitting a signal from the device to a lighting system, receiving a signal from the lighting system, storing the signal in the device, manipulating the device, for example, by changing the direction from the first lighting system to a second lighting system, and changing the color of the second lighting system by pressing a button on the device.
The following are descriptions of illustrative embodiments that when taken in conjunction with the following drawings will demonstrate the above noted features and advantages, as well as further ones. In the following description, for purposes of explanation rather than limitation, specific details are set forth such as the particular architecture, interfaces, techniques, etc., for illustration. However, it will be apparent to those of ordinary skill in the art that other embodiments that depart from these specific details would still be understood to be within the scope of the appended claims. Moreover, for the purpose of clarity, detailed descriptions of well-known devices, circuits, and methods, such as power supply systems for the lights, etc., are omitted so as not to obscure the description of the present system.
It should be expressly understood that the drawings are included for illustrative purposes and do not represent the scope of the present system. In the accompanying drawings, like reference numbers in different drawings designate similar elements.
As used herein, the terms used for a device for wireless control may include “remote control unit”, “remote control”, and “pointing device”. These terms are to be understood as having the same meaning and hence being interchangeable throughout the detailed description to follow.
The term “lighting system” as used throughout includes but is not limited to lighting panels, signage systems, flexible (rope) lighting, tube lighting, and shelf lighting systems.
Throughout this description, the term “button” is used in reference to the actuation device for activating the pointing device. As a person skilled in the art will realize, the term “button” also refers to other actuation devices including a switch, mechanical button, a touch sensitive display screen, and voice activation.
Before turning to the illustrative description of using remote control devices to modify the color of a lighting system, a few configurations of lighting systems and remote control devices follows, illustrating, for example, that lighting systems may comprise any number of lighting elements and that communication channels between remote control devices and lighting systems may be unidirectional as well as bi-directional. The remote control devices that are illustrated in
The lighting elements that form part of the described systems are capable of reproducing visible light having a plurality of desired colors and intensities. The lighting elements may be realized in the form of multi-color light emitting diode (LED) devices that, for example, conform to the RGB system of colors. Nevertheless, any other suitable controllable multi-color light emitting elements may be used without departing from the scope of the present system.
The signal transmitter 109 is configured to transmit a signal 117. As will be discussed below, the signal 117 is preferably transmitted as a more or less focused (e.g., narrow) beam of electromagnetic radiation. The signal 117 is received by a receiver 111 in a lighting system 103 that also includes a plurality of lighting elements 115a-c as well as a controller 113. Each of the lighting elements 115a-c are individually controllable via the controller 113 to emit light 131a-c having a given characteristics, such as color and intensity. As a person of ordinary skill in the art will understand, the system 103 may comprise any number of lighting elements arranged in any desired spatial configuration relative to each other, including a rectangular array of elements and more irregular distributions. In addition, the light 131a-c emitted may be distinctive and separate in one embodiment. However, in another embodiment, the light 131a-c emitted may be blurred together in portions as long as separate color portions are also present.
To facilitate the following discussion, adjusting a color characteristic of light will be described. However, as would be readily appreciated by a person of ordinary skill in the art, the following discussion also is applicably to controlling other characteristics of emitted light including intensity, hue, saturation, and the like.
The transceiver 209 is configured to operate a bi-directional communication channel 217 with a corresponding system transceiver 211 connected to a controller 213 in the lighting system 203. Information regarding desired characteristics of emitted light including an emitted color of light and information regarding desired and emitted intensity of light is exchanged via the bi-directional channel 217. The storage device 205 may store a database of such information such as data on previously selected color characteristics, including colors and intensities. The storage device 205 may provide the stored information to the color information data generator 200 as needed. The signal 217 is preferably transmitted as a more or less focused beam of electromagnetic radiation, although some embodiments that utilize a remote control device do not necessarily utilized a focused beam in order to function according to the present system.
The signal 217 is received by the receiver 211 in the lighting system 203 that also includes a plurality of lighting elements 215a-c coupled to the controller 213. The lighting elements 215a-c are individually controllable via the controller 213 to emit light 231a-c having a desired color and/or intensity. The system 203 may include any number of lighting elements arranged in any desired spatial configuration relative to each other, including a rectangular array of distinctive elements and more irregular distributions.
The remote control devices 101, 201 as embodied in
It is also to be noted that the controllers of the systems discussed above may be configured to adjust characteristics of light emitted from the lighting elements gradually over a period of time. For example, the color of light emitted from the lighting elements may change gradually over a period of time. Moreover, in a system having several lighting elements, when a first lighting element has obtained a desired color as a result of control by a remote control device of the present system, one or several other lighting elements of the system may obtain the same color if desired.
To facilitate modification of an emitted characteristic of the lighting system, the present system provides an indication as to which characteristics may be emitted by that system prior to characteristic selection. For example, to modify the color of a lighting panel, the user is provided a visual perception of the colors displayable by that panel. To facilitate modification of an intensity emitted by the lighting system, the present system provides a visual indication as to which intensities may be emitted by that system prior to intensity selection.
Further discussion of the present system will facilitated with reference to FIGS. 3 and 4A-4E.
By way of example, a suitable panel for use with the present system may be constructed in accordance with European Patent Application Serial No. 051049286.6, entitled “Illumination System,” wherein a backlight system having a light guide is described. The system may include a plurality of lighting elements (e.g., LEDs, sub-panels, etc.) that may create different colored regions such as is shown in
In a further embodiment, the lighting system 403 may indicate it is in-focus or in line to the device 401 by a producing a sensory indication, for example, flashing, producing an auditory signal, etc. during act 330. Further, actuation by the pointing device may occur by moving the signal 417 emitted by the pointing device 401 within one lighting system or between several lighting systems. Actuation (e.g., acts 320 and/or 330) may also occur by actuating and de-actuating the pointing device, or by actuating the pointing device prior to directing the pointing device toward the lighting system 403.
In another embodiment, the user may simply select panel 8 verbally without the panels displaying panel indication numbers, by for example, verbally describing the color emitted by a desired panel. For example, the user after viewing the available colors, may simply state, “green” or other words that are sufficient to differentiate a desired color from other available colors.
In a further embodiment, a user may simply point at the panel 403 to initiate act 320. The pointing may be captured by an image acquisition device, such as camera 410 which may be operably coupled to the controller 113. The controller 113, for example utilizing computer vision techniques, may identify both acts 320 and 330 for actuation and selection. These and other suitable methods of actuation and selection may be utilized as would readily be appreciated by a person of ordinary skill in the art.
While the light emitted by the lighting panel 403 may be distinctive, as for example shown in
As should be clear, any of the systems and devices illustratively described herein may be repeated one or more times within a given lighting application, as illustratively described with regard to
