Control instructions are transmitted to receivers by modulating light sources to generate light beams that are modulated with digital data streams for inducing control instructions in the light beams. Each light beam is applied to a pixel shaper element of a pixel shaper assembly to produce a light pixel, each light pixel carrying the control instructions of the light beam, each light pixel having a perimeter defined by the pixel shaper element. The pixel shaper assembly combines the light pixels into an image without significant overlap or voids between the light pixels. The light pixels are directed toward a projector lens for transmission toward the receivers. In a receiver, an optical receiver detects a light pixel. A controller decodes the control instructions received in the detected light pixel and uses the control instructions to control a function of the receiver.

The present invention relates to lighting fixtures which are mounted into architectural finished surfaces such as ceilings, walls and floors, and is applicable to new installations as well as the renovation of existing surface-mounted fixtures. One embodiment relates to a modular lighting device for retro-fitting to an existing lamp housing which is flush mounted or countersunk into an opening of a ceiling or interior surface of a building, the modular lighting device comprising a lamp-fitting configured for receiving a light source and configured for attachment to the existing lamp housing, and reflector for reflecting and/or modifying light from the light source, the reflector comprising a narrow top section configured for attachment to said lamp-fitting, and a wider bottom section for covering said opening.

The present disclosure is directed to in grade light fixtures and recessed luminaires and subassemblies thereof, including, for example, a heat sink (10) and pivot (16) for a recessed luminaire (2), a gasket (100) for the recessed luminaire (2), and an outer box (70) and cover (4) for installation of the recessed luminaire (2). The recessed luminaire (2) comprises: a housing (6) having an internal surface (18); and a light subassembly (8) engaged with a thermally conductive body (10), the light subassembly (8) having a first end (53) and a second end (54), wherein the first end (53) of the light subassembly (8) is pivotally secured to a pivot (16) arranged on, in, or proximate to the internal surface (18) of the housing (6). The thermally conductive body (10) is in thermal contact with the internal surface (18) of the housing (5). The recessed luminaire (2) further comprises a dehumidifier (90).

A lighting apparatus includes a light source module, an internal housing, an exterior housing and a sliding track. The light source module including a LED module. The LED module may include multiple types of LED chips of different parameters that may be controlled to mix a desired parameter. The internal housing has a light opening and a protruding block. The light source module is fixed to the internal housing and a light of the LED module passes through the light opening. An exterior housing having a sliding groove. The exterior housing encloses the internal housing and allows the protruding block of the internal housing moving along the sliding groove to change a tilt angle of the light with respect to the exterior housing. The sliding track is used for the exterior housing to move along the sliding track for further adjusting an output direction of the light.
