摘要:
A luminaire comprising a heat spreader and a heat sink disposed around and thermally communicates with the heat spreader. The heat sink forms a trim plate configured to be disposed completely external of a can light fixture or an electrical junction box. The luminaire also includes an optic securely retained relative to one of the heat spreader and the heat sink on one side of a plane defined by a lower surface of the trim plate and extends to the other side of the plane defined by the lower surface of the trim plate, as well as a light source disposed on the heat spreader and comprising a plurality of light-emitting diodes (LEDs). The plurality of LEDs are positioned entirely on one side of the plane defined by the lower surface of the trim plate. The light source is in thermal communication with the heat spreader.

A wavelength converting bandage including a substrate with an external surface and an internal surface. The wavelength converting bandage includes a plurality of quantum dots, each quantum dot individually sized to emit light within a wavelength range of 613 nm to 846 nm, defined as converted light. The wavelength converting bandage includes at least a portion of the substrate constructed to adhere to skin. The substrate may receive ambient light from the environment on the external surface and may emit converted light toward the skin.

A system for luring pests including a pest detector and a pest lure. The pest detector may be adapted to generate a type detection signal having a value indicative of a type of a pest in proximity to the pest detector. The pest lure may be in electrical communication with the pest detector and adapted to activate responsive to the type detection signal.

A luminaire comprising a light source comprising a plurality of light emitting diodes (LEDs) and a combination heat spreader and heat sink disposed in thermal communication with the light source such that the combination heat spreader and heat sink facilitates transfer of heat away from the LEDs. The combination heat spreader and heat sink have an outer dimension that is larger than an opening defined by a nominally sized can light fixture and an opening defined by a nominally sized electrical junction box. A back surface of the combination heat spreader and heat sink is configured to permit the luminaire to be flush mounted on the mounting surface.

A lighting assembly comprising a light source operable to emit light, a first primary optic, and a second primary optic. Each of the first primary optic and the second primary optic are configured so as to reflect light incident thereupon to be emitted by the lighting assembly. Additionally, each of the first primary optic and the second primary optic are positioned such that a first portion of light emitted by the light source is incident upon the first primary optic and a second portion of light emitted by the light source is incident upon the second primary optic. At least one of the first primary optic and the second primary optic is operable to me rotated to change the relative position thereof with respect to the light source.

A lighting device may include a light source, a control circuit, and a communication device positioned in communication with the control circuit. The communication device may be configured to receive a transmission from a user device, and the transmission may include a data structure. The data structure may include a show packet and an event packet. The show packet may include an ID string and information regarding a number of event packets associated with the data structure, and the event packet may include information regarding a lighting spectrum, a fade type, a fade duration, and a hold duration. The control circuit may be configured to operate the light source to emit light transitioning from a present light emission having a present spectral power distribution to a light emission having spectral power distribution indicated by the lighting spectrum according to the fade type and fade duration.

A lighting apparatus comprising a plurality of luminaires, each luminaire comprising a controller configured to operate the luminaire and positioned in communication with a computerized device. Each luminaire may be selectively operable to emit source light characterized by a dominant source light wavelength within a range from 390 nanometers to 750 nanometers. Additionally, at least two of the plurality of luminaires may be operable to emit source lights with different dominant source light wavelengths, and such that one or more source lights emitted by the plurality of luminaires may combine to form a combined light at a distance from the plurality of luminaires defined as a combining distance. Furthermore, the dominant source light wavelength of at least some of the luminaires of the plurality of luminaires may be variable with time.
