An LED light bulb with integrated power supply, and which may incorporate integrated communications and processing functions. The LED light bulb is designed to be efficiently manufactured in mass quantities using automated assembly techniques, and is constructed to exhibit the spatial light pattern of a regular incandescent bulb as closely as possible. Where communications and processing functions are integrated, the LED light bulb is able to communicate via wireless communications to a mobile phone, notebook, tablet, or other computing device.

A luminaire (61) is disclosed with a close coupled ballast (62) having a support arm (66) from which is suspended or hung a reflector, and preferably a variable focus reflector (41), having either a single ended lamp (3) or double ended lamp (23). The luminaire (61) is supported from a greenhouse rafter (9) by filaments (10, 11) which are connected one to the ballast (62) and the other to the free end of the support arm (66). In one embodiment the arm (66) is connected to a rigid side plate (64) which is mounted on the ballast (62). In another embodiment the arm (66) is connected to a side plate (164) which is hinged. The arrangement enables flimsy reflectors (41) to be close coupled with electronic ballasts in a way which minimises Radio Frequency Interference (RFI).

An illumination device includes a supporting base, and a light-emitting element inserted in the supporting base. The light-emitting element includes a substrate having a supporting surface and a side surface, a light-emitting chip disposed on the supporting surface, and a first wavelength conversion layer covering the light-emitting chip and only a portion of the supporting surface without covering the side surface.

An item of clothing has a strip 502 of a reflective tape surrounded by florescent material. Embedded light-emitting devices 113 are connected to a loom of power and data cables and are supported on a flexible printed circuit board 101. Respective windows 1213 are provided for each light-emitting device, in which a hole cut through the reflective tape is covered by a clear plastics material having a first flap 1203 and a second flap 1204. The first flap is folded around the flexible printed circuit board and is secured by the second flap being further folded around the first flap. The clear plastics material is secured to the clothing fabric by an adhesive film 701 through which the holes have also been cut.

A light fixture can include a housing comprising at least one wall that forms a cavity, wherein the housing complies with applicable standards for a hazardous environment. The light fixture can also include an antenna assembly disposed on an outer surface of the housing. The antenna assembly can provide communication with another device within the hazardous environment without compromising the applicable standards for the hazardous environment.

An LED device holder, an LED lighting system and a method of manufacturing an LED lighting system are described herein. An LED lighting system includes a holder defining an aperture. The aperture has a perimeter and a fillet adjacent the perimeter. The fillet has a radius greater than or equal to 2.0 mm and less than or equal to 4.6 mm. An LED array is mechanically coupled to the holder. The LED array has a light emitting surface exposed through the aperture.
