  • Patent number: 10260711
    Abstract: Light control films, and lighting devices including the same, are disclosed. The light control films include a single layer of light transmitting material having a first side and a second side. A plurality of first microstructures are formed in the first side. The first microstructures are configured to receive incident light from a light source and produce an off axis (e.g. batwing) light distribution in a field downstream of the second side of the light control film. In some embodiments, a plurality of second microstructures is formed on the second side of the light control films and are configured to reduce the glare produced by light emitted from the light source passing through the film.

  • Patent number: 10254382
    Abstract: A system and method for determining vehicle position uses light based communication (LBC) signals and a received signal strength indicator (RSSI) to determine the vehicle position. Each vehicle includes a LBC system having an array of transmitting light emitting diodes (LEDs) and an array of receiver photodiodes for transmitting and receiving pulsed light binary messages. Each LBC system has a controller coupled to the transmitter diodes and receiver diodes. The controller includes a vehicle communication module that may be executed by a processor to determine the distance. The processor models a first distance between a first transmitting LBC system and a first receiving LBC system, then models a second distance between a second transmitting LBC system and the first receiving LBC system, and then determines the distance between the first vehicle and the second vehicle using trilateration of the first distance and the second distance.

  • Patent number: 10256905
    Abstract: Techniques are disclosed for programming a luminaire with location information, referred to herein as commissioning. Location information may include relative location information (e.g., the position of the luminaire relative to a reference point) and/or absolute location information (e.g., global coordinates for the luminaire). A commissioned luminaire can be configured to emit its location information via light-based communication (LCom). In some cases, the luminaire can be commissioned manually, by hard coding the luminaire with its location either at the luminaire itself or using a device (e.g., a smartphone, tablet, or a dedicated luminaire commissioning device) to program the luminaire with location information. In some cases, the luminaire can be commissioned automatically. In some cases, the luminaire may be configured to provide visual, aural, or tactile feedback to indicate that the luminaire has not received location data or that the luminaire has been moved.

  • Patent number: 10251241
    Abstract: Techniques and architecture are disclosed for gesture-based control techniques for lighting systems. In some cases, the lighting system may include a camera and/or other suitable componentry to interpret gestures made by a user for controlling light output. In some such cases, the gesture performed and/or the location of the gesture may determine how the light output is controlled. In some cases, the gestures may be performed by moving a mobile computing device, such as a smartphone, tablet, or dedicated light controller device. In some such cases, sensors included in or otherwise operatively coupled to the computing device (gravitational sensors, accelerometers, gyroscopic sensors, etc.) may be used to detect the movement of the device and the related gestures. The gestures may be used to navigate a user interface that allows a user to control light output by adjusting different attributes of the light output, such as light intensity and color.

  • Patent number: 10244609
    Abstract: Techniques are provided for bi-directional communication between a power supply and one or more light engines (and/or other lighting system components) via the existing power lines so that no additional communication wires are needed. In particular, the power supply can transmit information by modulating its output (voltage or current) and the light engine (or other lighting componentry, such as a sensor) can communicate back by modulating how much power it draws from the power supply. Any suitable type of modulation scheme can be used, and a master-slave arrangement can be used to control the bi-directional communication if so desired, so as to avoid multiple devices communicating over the power line communication channel at the same time. Other embodiments allow a multiple simultaneous communications over the power line communication channel.

  • Publication number: 20190082610
    Abstract: In general, one embodiment of the present disclosure includes a horticulture lighting device having a plurality of LED light channels that may be selectively energized to produce a predefined light pattern. Each of the LED light channels may emit one or more wavelengths and may be pulsed at a rate that may be imperceivable to a human eye, e.g., at 120 Hz to 720 Hz. Plants may respond biochemically to light patterns that include a period of delay between pulses of light, e.g., from 500 microseconds to 5 milliseconds. The biochemical response has been shown to significantly increase plant growth, e.g., up to 100%, relative to plants grown with lighting systems that use continuous, non-pulsing light sources. Thus, aspects and embodiments disclosed herein include a horticulture device capable of emitting light patterns which introduce a predefined delay period between energizing/pulsing of LED light channels to aid photosynthesis.

  • Patent number: 10237951
    Abstract: A luminaire having an electronically adjustable light beam distribution to provide upward illumination creating color gradients on a ceiling. The color gradients may be in patterns that mimic color gradients of a sky, including, for example, color gradients that mimic sunrise, sunset, sun at different times of day, a rainy day, clouds, the sun, moon, etc. The color gradients may change over time and/or may include one or more objects, e.g. clouds, the sun, moon, etc. and/or may move and/or change over time to create a dynamic sky on the ceiling. Multiple luminaires may be controlled by a system controller to produce coordinated color gradients across the light distribution areas of the multiple luminaires.

  • Patent number: 10237953
    Abstract: Techniques are disclosed for identifying and controlling light-based communication (LCom)-enabled luminaires. In some cases, the techniques include a luminaire communicating its ID to a computing device via one or more LCom signals. In some cases, a user may be able to aim a rear-facing camera of a smartphone at the luminaire desired to be controlled. Once the luminaire is in the field of view of the camera, the ID of the luminaire can be determined using one or more LCom signals received from the luminaire. The ID of the luminaire may be, for example, its internet protocol (IP) address or media access control (MAC) address or another unique identifier. Once a luminaire has been identified, commands can be issued to the luminaire to adjust one or more characteristics of the light output, such as changing the dimming percentage of the light output.

  • Patent number: 10225908
    Abstract: An active damping circuit is disclosed, which includes a peak current limiter, a drain source voltage limiter, a turn-on driver, a resistor shunt circuit, and a peak current sensor. The peak current sensor detects a rising edge of an input voltage from a phase cut dimmer by detecting a higher peak current. This drives a collector voltage of a second transistor of the peak current limiter low, which lowers a gate voltage of a first transistor of the peak current sensor, and forces it into a linear operating region, so it functions as a damping resistor. When the peak current sensor detects a decreased peak current, such that the turn-on edge of the input voltage is passed, the second transistor turns off, and the turn-on driver turns the first transistor on, such that the active damping circuit is waiting for a next edge of the input voltage.
