The at least one strip includes rails which extend along a length of said strip and are suitable for holding a fixing element at any point along the length of said rails.

A light board mounting system includes a fixture frame having a planar surface and a plurality of alternating bosses disposed along a length of the fixture frame. The system also includes a light board having a first side and a second side, a plurality of lights disposed along a length of the light board on the first side, and a pair of electrical contacts coupled to the plurality of lights and mounted to the second side of the light board and extending away from the second side. In addition, the light board mounting system includes a first edge and opposing second edge of the light board secured to the planar surface of the fixture frame between the plurality of alternating bosses, the second side of the light board being adjacent to the planar surface of the fixture frame and the pair of electrical contacts extending through the planar surface.

A linear luminaire is provided. The linear luminaire may include a housing body, two end caps, a face casing, and a back plate. The two end caps may be fixed onto two ends of the housing body. The housing body may include a top groove and a bottom groove. The top groove and the bottom groove may extend in a length direction with grooving openings oriented in opposite directions. The face casing may be fixedly clamped onto the groove opening of the top groove and forms an optical mixing cavity together with the top groove and the two end caps. The optical mixing cavity may be configured for accommodating a light-emitting circuit of the linear luminaire. The back plate may be clamped onto the groove opening of the bottom groove to form a power driving cavity together with the bottom groove and the two end caps.

The invention relates to a heat sink (10, 60, 120, 150) having a body (12) which includes a channel-shaped mounting formation configured to hold an electronic unit (40) in the form of an LED strip captive therein. The channel-shaped mounting formation defines has a slot which includes a mouth (22) having a transverse width which is less than a width of the electronic unit (40), and a nook (30) which is configured to permit mounting of the electronic unit (40) to the heat sink by passing the electronic unit through the mouth (22) and angularly displacing the electronic unit (40) relative to the mounting formation of the body (12). Instead of sliding the LED strip into the slot, which could damage the strip or result in poor application of thermal paste, the strip is mounted by applying paste and angularly and transversely displacing the strip relative to the body.

An illumination apparatus can include a light assembly having a housing section and an attachment section. At least one light emitting device is contained within the housing section. The attachment assembly can include a substantially flat base section and an attachment member extending outwardly from the base section. The attachment section of the light assembly can define a recess having a size and shape that is complementary to the attachment member of the attachment assembly, such that the light assembly and the attachment assembly can be releasably attached to each other by complementary frictional engagement of the attachment member of the attachment assembly and the attachment section of the light assembly when the attachment member is positioned within the attachment section.

A light emitting diode (LED) flat panel lighting fixture is provided. The LED flat panel lighting fixture comprises an LED flat panel lighting device comprising (a) one or more LEDs and (b) one or more first mating mechanisms. The LED flat panel lighting fixture further comprises a mounting bracket comprising one or more second mating mechanisms configured to each mate with a corresponding one of the one or more first mating mechanisms when the LED flat panel lighting device is rotated within the mounting bracket and with respect to the mounting bracket. The rotation of the LED flat panel lighting device within a plane of the mounting bracket and with respect to the mounting bracket causes the mating of the one or more second mating mechanisms with the corresponding ones of the one or more first mating mechanisms.

A light board mounting system includes a fixture frame having a planar surface and a plurality of alternating bosses disposed along a length of the fixture frame. The system also includes a light board having a first side and a second side, a plurality of lights disposed along a length of the light board on the first side, and a pair of electrical contacts coupled to the plurality of lights and mounted to the second side of the light board and extending away from the second side. In addition, the light board mounting system includes a first edge and opposing second edge of the light board secured to the planar surface of the fixture frame between the plurality of alternating bosses, the second side of the light board being adjacent to the planar surface of the fixture frame and the pair of electrical contacts extending through the planar surface.

A LED module mount, kit and method for mounting LED modules into lighting apparatuses, in particular for retrofit applications for retrofitting lighting apparatus frames with LED modules. Two module connectors connect to an LED module at opposite sides of the LED module so as to be in a parallel arrangement spaced apart by the LED module. Additional LED modules can be added to form a row of LED modules between the module connectors, with further rows of LED modules being added by adding a third and sequential modular connectors to stack rows of LED modules separated by a modular connector. One or more arms attaches to the modular connectors to connect the connectors to a light fixture. The arms are configured to be rotationally adjusted relative to the modular connectors to provide adjustability for accommodating varying light fixtures. The modular connectors and arms are configured to be adjusted in size, preferably by cutting the modular connectors and arms.

A presence or an absence of an occupant is detected, and an occupancy sensor signal is generated representative of an active state in which the presence of the occupant is detected, and an inactive state in which the absence of the occupant is detected. An ambient light sensor detects the ambient light level and generates an ambient light sensor signal representative of the ambient light level. Dimmable illumination is generated at a first dimming level, based on the ambient light level, corresponding to the active state and a second dimming level corresponding to the inactive state. A transition delay time between an onset of the inactive state and a transition between the first dimming level and the second dimming level may be controlled. The first dimming level, the second dimming level, and/or the transition delay time may be variably set or controlled locally or via a remote device.
