This disclosure relates to devices and systems for light control. More specifically, the disclosed embodiments relate to light control devices and light control systems to control a light strip in response to detection of an object or a motion of an object in a vicinity of an entranceway of a room.
Automatic light control is desired and already available to some extent. However, there are some problems with current automatic light control systems using a motion detector. For example, a light control system can turn off while a user is still present in a room but does not move enough. In other cases, the light stays on for a certain time period (or even indefinitely) after the user closes the door to a room, which results in wasted energy. A light control system with an automatic door jamb switch may solve some of the above issues. However, the automatic door jamb switch is typically installed by a qualified electrician when the home is built. Therefore, there exists a need for a light control system enabling desired automatic control and allowing easy installation and retrofitting in an existing space.
The present disclosure provides systems, apparatuses, and methods relating to control the light strip.
According to one aspect, a light control system for a light strip may include: an LED light strip configured to extend around at least a portion of a perimeter of an entranceway to a room; and a light control device including: a housing, a proximity sensor configured to detect a position of a door in a vicinity of the entranceway, a light controller disposed in the housing and in communication with the proximity sensor, and a battery pack removably installed in the housing and including a rechargeable battery; wherein the light controller is configured to control the light strip in response to a detected position of the door by the proximity sensor.
According to another aspect, a light strip control system may include: an LED light strip configured to be disposed along a majority of a perimeter of a frame enclosing an entranceway of a room; and a light control device including: an activity sensor configured to detect a position of a door in a vicinity of the entranceway, a light controller in communication with the activity sensor, and a rechargeable battery configured to power the light controller when the light controller is not powered by an AC power source; wherein the light controller is configured to control the light strip in response to a detected position of the door by the activity sensor.
According to another aspect, a light strip control system may include: an LED light strip; and a light control device including: an activity sensor configured to detect a position of a door in a vicinity of an entranceway, a light controller in communication with the activity sensor, and a rechargeable battery pack configured to power the light controller when the light controller is not powered by an AC power source; wherein the light controller is configured to control the LED light strip in response to a detected position of the door by the activity sensor.

A. Illustrative Light Control Systems and Light Control Devices
Light control device 22 is connected to light strip 24 to control on and off of the light from light strip 24. Light control device 22 may include a light controller 38 and an activity sensor or a first activity sensor 40. Light controller 38 may include a processor and a memory. Activity sensor 40 detects an object in a vicinity of entranceway 28, a motion in the vicinity of entranceway 28, or a motion relative to entranceway 28 and sends signals to light controller 38. Activity sensor 40 may be a passive infrared (PIR) sensor, a time of flight (ToF) sensor, a magnetic field detector or any other form of proximity sensor. In some embodiments, light controller 38 controls on and off of light strip 24 based a detected object in the vicinity of entranceway 28 or based on a position of the object in a vicinity of entranceway 28. In some embodiments, light controller 38 controls on and off of light strip 24 based a motion pattern of an object detected by activity sensor 40.
Continuing
In the illustrative embodiment, light control device 22 is disposed inside room 30 adjacent to first vertical portion 34 of frame 26, connected to connected end 44 of light strip 24 and positioned on floor 48 of room 30. Alternatively, light control device 22 may be disposed on the middle position of first vertical portion 34 and connected to connected end 44 on the middle position directly or may be disposed on floor 48 and connected to connected end 44 via wire.
As light control device 22 is disposed on first vertical portion 34 adjacent to a free side 50 of door 42, activity sensor 40 can detect opening of door 42 when free side 50 of door 42 moves away from first vertical portion 34 and detect closing of door 42 when free side 50 moves toward first vertical portion 34. In some embodiments, activity sensor 40 may be a time of flight (ToF) sensor. The ToF sensor measures the time it takes an infrared (IR) beam to reflect off a nearby object, and it can determine a distance to the object from that information. When door 42 opens, activity sensor 40 can determine a distance of door 42 to activity sensor 40 and/or a motion pattern of door 42. In this way, different light modes are possible by programming light controller 38. Light controller 38 may be configured to turn on or turn off light strip 24 based on a distance of door 42 to a reference object such as activity sensor 40 or a housing of light control device 22. For example, light controller 38 may control light strip 24 to turn on once activity sensor 40 detects that door 42 moves away from first vertical portion 34. In another example, light controller 38 may control light strip 24 to turn on when door 42 moves away a predetermined distance from light control device 22. That is, light strip 24 is not turned on immediately after door 42 is opened. Instead, light strip 24 is turned on after door 42 has opened the predetermined distance. In yet another example, light strip 24 is turned off after activity sensor 40 detects that door 42 moves near or touches first vertical portion 34. In yet another example, light strip 24 is turned off after activity sensor 40 detects a motion pattern of door 42. The motion pattern may be a speed of door movement greater than a threshold, a sequence of opening, closing and opening, or any combination of opening and closing.
In some embodiments, activity sensor 40 may be a passive infrared (PIR) sensor. The PIR sensor measures infrared (IR) light radiating from an object in its field of view. Humans and inanimate objects emit a certain amount of IR radiation. The PIR sensor may consist of at least one pyroelectric sensor and a Fresnel lens. The curved lens concentrates infrared radiation toward the pyroelectric sensor. That is, the sensor view is a beam pattern. The PIR sensor receives concentrated amount of infrared energy under certain zones. When an object, such as a person, passes in front of the background, the temperature at that point in the sensor's field of view will rise from room temperature to body temperature, and then back again. The sensor converts the resulting change in the incoming infrared radiation into a change in the output voltage and send out the signal. A field of view of the PIR sensor may be less than 180° and may be as wide as 360°.
In some embodiments, activity sensor 40 may be a proximity sensor. In one example, proximity sensor 40 is a magnetic field sensor such as a Hall Effect sensor and includes a sensing body disposed in housing 60 and a magnet 41 attached to free side 50 of door 42 and substantially aligned with the magnetic field sensor at a height direction H. In one example, magnet 41 faces light control device 22 when door 42 is closed. When door 42 moves away from light control device 22, the magnetic field detected by activity sensor 40 changes. The magnetic sensor detects the change of magnetic field to determine a distance of door 42 to the activity sensor 40 or detect a motion of door 42. Similarly, the magnetic field detected by activity sensor 40 changes when door 42 moves toward light control device 22. In some embodiments, light controller is configured to turn on light strip 24 when free side 50 of door 42 is detected to be spaced apart from first vertical portion 34 at a first predetermined distance (i.e., a door opening event) and turn off light strip 24 when the door is detected to be spaced apart from first vertical portion 34 at a second predetermined distance (i.e., a door closing event). The first predetermined distance is greater than the second predetermined distance. In one example, the second predetermined distance may be about zero.
It should be appreciated that various types of proximity sensors to detect a presence of a nearby object may be used as activity sensor 40. For example, the proximity sensor may be a short-range infrared (IR) sensor. In other example, the proximity sensor may be a capacitive sensor, a capacitive displacement sensor, a Doppler effect sensor, an inductive sensor, an optical sensor (e.g., photoelectric, photocell (reflective), a laser rangefinder), a passive sensor (e.g., charge-coupled devices), a passive infrared sensor, a passive thermal infrared sensor, a radar, a reflection of ionizing radiation sensor, a sonar, an ultrasonic sensor, or a fiber optics sensor.
It should be appreciated that activity senor 40 may be connected to a hinge side of door 42. The hinge side is opposite to free side 50 and connected to frame 26.
In some embodiments, light control system 20 may include a plurality of light strip clip 52 attached to frame 26 or on a wall adjacent to frame 26 to secure light strip 24. Light strip clips 52 may be attached on frame 26 via adhesive at selected positions. The light strip clip will be described in detail in
In some embodiments, light controller 38 and activity sensor 40 of light control device 22 are at least partially contained in a housing 60. In some embodiments, light control system 20 may further include a transceiver 64 disposed in housing 60 of light control device 22 to enable communication with an electronic device 65 such as smart phone. For example, a user may select a light control mode via a user interface on electronic device 65. Further, light control device 22 may send an alert to electronic device 65 alerting a low battery level of a battery pack 68.
As shown in
In some embodiments, light control system 20 may further comprise a sensor module 70 to detect a position/motion of a user's hand relative to entranceway 28 or to detect the user's hand signals and electrically communicate with light controller 38. Sensor module 70 may be disposed on at a position approximately around a middle point of first vertical portion 34 or a position to detect hand signals/hand gestures of a user. In some embodiments, sensor module 70 may be an accelerometer installed flush against first vertical portion 34 or a door jamb. In one embodiment, a spring 72 may be used to bias accelerometer 70 against the door jamb. When a user knocks or taps the door jamb gently, the vibration will be detected by accelerometer 70. Light controller 38 may be configured to recognize and determine different motion patterns of knocking/tapping by a hand of the user and activate corresponding light modes. Light controller 38 may be configured to control the light strip 24 only in response to the tapping patterns detected by accelerometer 70 when door 42 is detected by activity sensor 40 to be remained at an opening position for a preset time period or no door is present in entranceway 28. In other words, when a door is not detected at a preset distance from light control device 22 or no door installed in entranceway 28, controlling light strip 24 in response to detected tapping patterns from accelerometer 70 overrides the controlling light strip 24 in response to the signal from activity sensor 40. The tapping pattern may be a number of taps on the first vertical portion 34 or door jamb at a predetermined time period. For example, light controller 38 is configured to turn on light strip 24 when the tapping pattern is tapping once on first vertical portion 34 by a user and turn off light strip 24 when the tapping pattern is tapping twice on first vertical portion 34 by the user. In another example, light controller 38 is configured to turn on light strip 24 at a lower brightness when the tapping pattern is tapping three times on first vertical portion 34 by the user. Various tapping patterns may be possible to be recognized by light control 38 and control light strip 24 accordingly. It should be appreciated that accelerometer may be installed on the vertical portion or the door jamb at any appropriate position. For example, the accelerometer may be installed at a position between a middle point of the vertical portion or the door jamb as long as the tapping/knocking by the user can be detected by the accelerometer. In some embodiments, sensor module 70 may be a short-range infrared (IR) sensor that detects a position/a motion of a user's hand signals in a vicinity of vertical portion or a door jamb. The motion pattern may be the user's hand signals such as extending into entranceway 28 and then retracting back. For example, light strip 24 is turned on when the user waves a hand once across entranceway 28 and light trip 24 is turned off when the user waves a hand twice across entranceway 28. Various hand signals may be possible to create patterns recognizable by light controller 38.
In some embodiments, sensor module 70 may include a capacitive-touch sensor that detects a touch pattern of a user's hand on sensor module 70.
Although sensor module 70 is illustrated to be positioned separately from activity sensor 40, it should be appreciated that various configurations are possible. For example, a sensor module and an activity sensor may at least partially be enclosed in a sensor housing. In one embodiment where the sensor module is an accelerometer and the activity sensor is a proximity sensor or a short-range IR sensor, both accelerometer and the proximity sensor or the short-range IR sensor may be enclosed in the sensor housing. The sensor housing may be installed a halfway on the door jamb or at a position for easy detection of hand signals (e.g., tapping patterns). In some embodiments, an ambient light sensor may also be included in the sensor housing and all sensors are included in the sensor housing. Alternatively, the sensor housing and the housing for the light controller may be combined. That is, the control related components such as various sensors and light controller are integrated in one housing.
It should be appreciated that the sensor module may be any appropriate sensor module that that can detect the user's hand signals relative to the entranceway or an interaction of the user's hand to the vertical portion of the entranceway. For example, the sensor module may be a button to create a motion pattern by a user and the motion pattern is recognizable by the light controller.
Light control system 20 may further comprise a connecting device 90 to connect light control device 22 or light control system 20 with a home automation system.
Light control device 122 is connected to a first end of light strip 124 to control on and off of light strip 124. Light control device 122 may include a light controller 138 and an activity sensor or a first activity sensor 140a. First activity sensor 140a detects an object in a vicinity of entranceway 128 or a vicinity of first vertical portion 134 and sends signals to light controller 138. First activity sensor 140a may be a passive infrared sensor, a time of flight (ToF) sensor, a proximity sensor or a magnetic field detector. In some embodiments, light controller 138 controls on and off of light strip 124 based on a motion pattern of first door 142a or second door 142b detected by first activity sensor 140a or based on a presence of first door 142a or second door 142b in a vicinity of entranceway 128.
Continuing
Light control system 120 may further comprise a second activity sensor 140b and is held in a second housing 180. Second housing 180 is positioned adjacent to second vertical portion 136. Second activity sensor 140b is disposed in second housing 180 at a position to detect a position or a motion of second door 142b or first door 142a in a vicinity of second vertical portion 136. Signals from second activity sensor 140b may be transmitted to light controller 138 by data line along light strip or wirelessly. In other words, second activity sensor 140b is communicated with light controller 138 via the data line of light strip 124.
For instance, the light control device of this embodiment may be configured to turn on the light strip when the door (such as an edge portion of the door) is detected to be spaced apart from a housing of the light control device (such as the housing of first activity sensor 140a or the housing of second activity sensor 140b) by a first predetermined perpendicular distance and turn off the light strip when the door is detected to be spaced apart from the housing by a second predetermined perpendicular distance, and the first predetermined perpendicular distance is greater than the second predetermined perpendicular distance. In this manner, the light control device can be configured to turn on the light strip when a sliding door is opened by some desired amount, and to turn off the light strip when the sliding door is closed to a predetermined (and perhaps user selectable) extent.
In some embodiments, second activity sensor 140b is electrically connected to light strip 124 so that it is powered by voltage from distal end 146 of light strip 124.
Continuing
Light control device 222 is configured to control on and off of the light strip 224. Light control device 222 may include a light controller 238 and an activity sensor 240. Activity sensor 240 detects an object or a motion pattern in a vicinity of first vertical portion 234 of entranceway 228 and send signals to light controller 238. The object may be a person. Activity sensor 240 may send a signal to trigger the light on when the person walks across the entranceway or when a hand of the person passes through a plane containing the entranceway. In some embodiments, activity sensor 240 may be a PIR sensor.
Light controller 438 controls on and off of light strip 424 based on signals from first activity sensor 440a and is configured to have a plurality of light modes. In some embodiments, light control modes may be activated automatically based on a presence of an object or a motion pattern of an object in a vicinity of an entranceway. For example, light is controlled to be turned on when an object (e.g., a door) is detected to move a predetermined distance away from the entranceway and to be turned off when the object is detected to move toward the entranceway. In one example, a sensing distance to trigger the operation of the light strip may correlate a position of first activity sensor on a housing of light control device 422. In one embodiment, the sensing distance is fixed. However, the position of first activity sensor 440a on a housing of light control device 422 may be adjusted and thus the position of the object at which the light is controlled to be turned on or off can be adjusted although the sensing distance is fixed. For example, first activity sensor 440a may be disposed on a selector mechanism on the housing of light control device 422. A user can adjust the position of first activity sensor 440a via the selector mechanism such that, for instance, light is turned on when a door has opened to a desired distance.
Light controller 438 may be configured to recognize and determine different motion patterns and activate corresponding light modes. The motion patterns may be based on the interaction of an object relative to the entranceway. The object may be a door of the entranceway or a person. In some embodiments, a first motion pattern may be a movement of the door away from the door or opening of the door, which corresponding to a mode of light being on. A second motion pattern may be a movement of the door toward the door or closing of the door, which corresponding to a mode of light being off. In another example, a motion pattern of opening, closing and reopening of the door may correspond to a “no disturbance” mode. At the “no-disturbance” mode, the light strip 424 is off even the door is open. Similarly, in a setting in which there is no door at an entranceway, a motion pattern of a user's hand gesture of extending into, retracting and reextending into the entranceway can be recognized and interpreted as a command to activate the “no-disturbance” mode. A “night light” mode may further be implemented via another motion pattern. For example, a motion pattern of opening, closing, reopening, closing and reopening of a door may correspond the “night light” mode in which light stays on at a lower brightness (approximately 20% of brightness for example) to provide night light for the room or an adjacent room. Motion patterns may include various combinations of the movements of the object relative to the entranceway, various interactions with the entranceway and/or speeds of the movement. Light controller 438 may be configured recognize the motion patterns and activate the light modes accordingly. It should be appreciated that the light modes are not limited to the modes described above and various light mode may be possible. For example, the mode may include a specific time, a door distance, a light intensity, a light color, a period for light being turning and a motion speed of an object, and any combinations of above parameters. When the light controller is connected to an electronic device such as a smart phone, a user may input a desired mode via a user interface and the light controller will execute the instructions and control the light accordingly.
In some embodiments, light control device 422 may include a socket adapter configured to plug into a light fixture in the room to draw power. Socket adapter is described in detail in
In some embodiments, light control system 420 may further comprise an accelerometer 470 electrically communicated with light controller 438. The interaction with the entranceway is knocking or tapping on the entranceway. For, example, accelerometer 470 may be installed to flush up against a door jamb. When a user knocks or taps the door jamb or an area adjacent to accelerometer 470 gently, the vibration will be detected by accelerometer 470. Light controller 438 may be configured to recognize different motion patterns of knocking/tapping and activate corresponding light modes or control the light strip accordingly.
In some embodiments, light control device 422 may further comprise an ambient light sensor 480 to detect ambient light and determine light intensity of light strip 424 appropriate for the surrounding environment.
In some embodiments, light controller 438 may be configured to connect with an electronic device 466 such that the light control modes may be set up by a user via a user interface on electronic device 466. Light controller 438 may be communicated with electronic device 466 wirelessly. For example, a transceiver 464 may be included in a housing of light control device 422. In one embodiment, electronic device 466 may be a smart phone.
Via the light control application in the electronic device, a user can customize the light control mode. For instance, the light actuation may be set up to depend on the ambient light conditions via a user interface on the electronic device. In one example, a light control system may be configured to control the light strip installed under a kitchen cabinet, by turning on whenever the overhead light is turned on and turning off when an ambient light intensity exceeds a threshold. The ambient light intensity may be detected by an ambient light sensor. The user may also set up different modes for different hours in the day.

The different embodiments and examples of the light control devices and light control systems for a room described herein provide several advantages over known solutions for better user experience. For example, illustrative embodiments and examples described herein can control the light strip automatically based on a door position and the user's hand signals. In an entranceway with a door, the light strip is controlled by opening and closing of the door. When the door remains at an open position, the user's hand signal controls the light strip. In this way, the light strip can be controlled seamlessly between a control mode of the light activation/deactivation in response to a door position and a control mode of the light activation/deactivation in response to the user's hand signal. Further, the light control system can be used in an entranceway without a door and the light strip is simply controlled in response to a user's hand signal because a door cannot be detected in the entranceway.
Additionally, illustrative embodiments and examples described herein allow the user to calibrate the time of turning on or turning off the light from a light strip. Thus, the light control devices and system are user friendly.
Additionally, and among other benefits, illustrative embodiments and examples described herein are versatile and allow for use in different settings such as a closet with a door or without door. Further, illustrative embodiments and examples may be used in any inner space having an entranceway such as a closet, a storage room, a cabinet, or essentially any space where it is desirable to provide and/or control the lighting based on motions at the entranceway, such as motions of a door disposed in the entranceway.
Additionally, and among other benefits, illustrative embodiments and examples described herein allow one activity sensor at one location is powered by a LED light strip and electronically communicated with a light control device at another location via the LED light strip such that the wiring and/or data line can be simplified.
Additionally, and among other benefits, illustrative embodiments and examples described herein allow a user to calibrate and adjust a field of view of a PIR sensor of the light control device. In this way, one configuration of a Fresnel lens of the PIR sensor can be used in various applications while satisfying the user's preference.
Additionally, and among other benefits, illustrative embodiments and examples described herein incorporate a removeable battery pack in a housing the light control device. The battery pack is rechargeable and can be used as a primary power source and/or a supplement power source. Thus, a power is always available for the light control devices and systems.
Additionally, and among other benefits, illustrative embodiments and examples described herein allow simple light control by motion patterns of an object adjacent an entranceway of a room.
Additionally, and among other benefits, illustrative embodiments and examples described herein allow an integration of the light control devices and systems with an existing home automation system.
Additionally, and among other benefits, illustrative embodiments and examples described herein allow adjustment an angle of light beam from a light strip and the desired light beam direction can be set up by a user using the clips.
No known system or device can perform these functions. However, not all embodiments and examples described herein provide the same advantages or the same degree of advantage.
