Abstract: An augmented reality-based lighting design method includes displaying, by an augmented reality device, a real-time image of a target physical area on a display screen. The method further includes displaying, by the augmented reality device, a lighting fixture 3-D model on the display screen in response to a user input, where the lighting fixture 3-D model is overlaid on the real-time image of the target physical area. The method also includes displaying, by the augmented reality device, a lighting pattern on the display screen overlaid on the real-time image of the target physical area, wherein the lighting pattern is generated based on at least photometric data associated with the lighting fixture 3-D model.

Abstract: A method of lighting control includes detecting, by a control device, whether an AC power is available, where the availability of the AC power is controlled by a switch. The method further includes providing, by a driver, a driver power to a light source if the driver power was not provided to the light source when the AC power was last available. The driver generates the driver power from the AC power.

Abstract: A lighting device includes a light source, an auxiliary device, and a control device configured to detect toggles of a switch that controls availability of an input power to the lighting device including the light source. The control device is configured to change an operation mode of the auxiliary device based on the toggles of the switch.

Abstract: A trim for a lighting fixture includes a trim structure, a processor disposed on the trim structure, and an interface electrically coupled to the processor. A power is provided to the processor from a power source of the lighting fixture via the interface.

Abstract: A lighting fixture includes a light emitting diode (LED) light source, a clock module, and a controller configured to control one or more characteristics of a light emitted by the LED light source based on time information received from the clock module. The controller is further configured to determine a current time of a day from the time information received from the clock module.

Abstract: A street light fixture includes an audio sensor configured to detect a sound and to generate an electrical signal from the sound. The street light fixture further includes a controller configured to determine whether the sound is produced by an automobile accident based on the electrical signal. The street light fixture further includes a light source configured to provide a visual notification of the automobile accident in response to the controller determining that the sound is produced by the automobile accident.

Abstract: A lighting system includes a first lighting fixture that includes a first microphone and a first transmitter. The first transmitter is configured to transmit a first digital audio stream generated based on a sound. The lighting system further includes a second lighting fixture that includes a second microphone and a second transmitter. The second transmitter is configured to transmit a second digital audio stream generated based on the sound, where the sound is received by the first microphone and by the second microphone. The lighting system also includes a central processor that can process the first digital audio stream and the second digital audio stream to identify the sound.

Abstract: A projection fixture includes a lighting module that emits a light, and a projection module that projects an image. The projection fixture further includes a controller that controls operations of the lighting module and the projector module, where the light emitted by the lighting module is used for projecting the image and for illumination.

Abstract: A projection system includes a recessed projection fixture that includes a lighting module configured to emit a light and a projection module configured to project an image. The light emitted by the lighting module is used for projecting the image and for illumination. The projection system further includes a sensor, where the projection module projects the image in response to an occupancy detection by the sensor. The recessed projection fixture is oriented to direct the image toward a surface below the recessed projection fixture.

The method further includes providing, by a driver, a driver power to a light source if the driver power was not provided to the light source when the AC power was last available. The driver generates the driver power from the AC power.

Abstract: A system of projection fixtures includes a first projection fixture recessed in a ceiling, where the first projection fixture includes a first projector device. The system further includes a second projection fixture recessed in the ceiling, where the second projection fixture includes a second projector device. The first projector device is positioned to project a first image on a first surface below the ceiling, and the second and projector device is positioned to project a second image on a second surface below the ceiling.
