Abstract:
In an embodiment, a luminaire includes a housing with a reflector. A rail is positioned near the reflector and has a light thereon which is configured to emit light into the reflector. The light is reflected from the reflector and passes through a diffuser that can act to ensure the emitted light is desirably defuse. In an embodiment, the diffuser can be removed from the housing for service or replacement.
Abstract:
A control device may include a removable faceplate, a planar printed circuit board (PCB), a structure located between the faceplate and the PCB, one or more LEDs (e.g., side firing LEDs) mounted to the PCB, and a light-guiding component. The structure may include an antenna configured to transmit or receive radio frequency signals. The faceplate may be configured to be mounted to the control device, and may include a light-conductive body and an opaque material provided on a front surface of the faceplate. At least one indicia may be engraved in the opaque material. The light-guiding component may include a planar portion and a curved portion. The planar portion may be located between the faceplate and the structure. The curved portion may extend between the LEDs on the printed circuit board and the planar portion to transmit light generated by the LEDs to the faceplate to illuminate the indicia.

Abstract:
The fundamental structural element of the developed lighting column is the body (1) in the shape of a pipe, which is made of a composite, mainly polyester and glass resin, usually chemically bonded, as well as glass fibers. The composite contains a luminophore, which constitutes from 2% to 8% of the column structure mass, however, most favourably, the composite mass contains at least 3% of filler that has flare effects. Favourably, as luminescent materials are used powders with filler grain size of between 10 and 40 micrometers. Inside the body pipe (1) a light source (4) is installed, which can, favourably, be a LED lamp, emitting visible white light with low power, i.e. from 1 to 5 Watt [W]. The composite lighting column is also equipped with a louver fitting (3), and a luminophore is also blended with a mixture that constitutes the external coating (2). However, additionally the lighting column is connected to a motion detector (5), which constitutes an element of the body (1) or which is placed nearby. Similarly, the body (1) is covered with an external coating (2) made of gelcoat and is in a colorless or colored version, or with a fully or partially printed coating, wherein, to the gelcoat mixture made of composites a luminophore is added.
