An LED lighting array for illuminating an area with the lighting array comprising a plurality of LED devices set in conical or elliptically conical reflectors, each of which is mounted upon a plate, each of which may be set at various angles to one other, and each of which is backed by a series of elements, first a copper support element, then an optional layer of graphite foam, followed by an aluminum plate, and then an arrangement of copper fins operably lined to a thermal mass mate. The copper support element includes support planes that are off-set relative to each adjacent plate and are in at least three different planes relative to each other. The backing plates may efficiently dissipate heat produced by the LEDs. The apparatus can be mounted upon a stand to illuminate an area such as a portion of a car park, building entrance or the like.

A lighting fixture includes a light emitting assembly that has a metal plate with opposite first and second surfaces, an LED mounted to the first surface of the metal plate and a foamed metal mounted to the second surface of the metal plate. The light emitting assembly is mounted in a housing that has a rear wall, a plurality of sidewalls projecting from the rear wall and an open front. The foamed metal faces the rear wall of the housing at a position spaced from the rear wall and the LED faces out from the open front of the housing. Openings are provided between the sidewalls of the housing and the light emitting assembly to accommodate a flow of cooling air between the light emitting assembly and the sidewalls and the rear wall of the housing.

A motor vehicle lighting device includes structural elements with a housing, at least one light module accommodated inside the housing, and at least one light source cooperating with an optical surface. The light module is provided with a heat sink, a generator of an air flow, and a single air duct suitable for cooperating with the generator of the air flow such as to direct the generated air flow towards the heat sink of the at least one light module. The air duct is formed by an open part added in the housing, and at least one closing structural element suitable for closing all or part of the added part.

A lighting device having separate compartments for its electronics components and heatsink is disclosed. In some embodiments, the lighting device has a waterproof electronics compartment that extends at least partially through the heatsink.

An elongated heatsink structure retaining single and/or bi-directional light sources that receive variable power input(s) through at least one endcap coupled to the elongated heatsink structure.

An LED lighting device comprise a lamp cap; a case, connected to the lamp along in a first direction and having a cavity; a power supply disposed in the case; connected to the lamp along in a first direction and having a cavity; and a light emission unit. The light emission unit and the heat exchange unit are connected to form a thermal conduction path, the light emission unit and the power supply are electrically connected. When the first direction is substantially parallel to the horizontal plane, the light emitting unit of the LED lighting device provides downward light emission. The fixing unit comprises a first member, and a second member, the first member and the second member are in a form of slide connection.

A luminaire includes a housing having a top wall and a sidewall. A first fin extends from the top wall and a second fin extends from the side wall. A light emitter assembly having a heat sink includes a third fin extending from the heat skink configured to mate with the first and second fins. The luminaire can also include a light emitter assembly that can be selectively connected to the housing in multiple orientations.

A lighting apparatus includes a circuit board and light emitting diodes (LEDs) attached to the circuit board. The LEDs are arranged in an array of row and columns and are attached to the circuit board are arranged in a single plane. A support substrate supports the circuit board. Optical elements are configured to redirect light from the plurality of LEDs. Each optical element is substantially the same as all other optical elements. Each LED is associated with a single optical element and each optical element is associated with a single LED. The lighting apparatus is configured to direct light away from the circuit board so that the light is directed so as to illuminate a substantially rectangular area that is off-center relative to the light assembly. The substantially rectangular area has an edge that is at least 14 feet in length.

In embodiments of the present invention, a method and system is provided for commissioning improved intelligent, LED-based lighting systems. The LED based lighting systems may include fixtures with one or more LED light bars, integrated sensors, onboard intelligence to send and receive signals and control the LED light bars, and network connectivity to other fixtures.

A light source includes a plurality of light emitting diodes, with at least some light emitting diodes sized between 30 microns and 500 microns. A plurality of micro-optics are associated with a light guide plate and sized less than 1 millimeter, with each micro-optic positioned over at least one of the plurality of light emitting diodes. At least some of the combinations of light emitting diode and micro-optics associated with the light guide plate are positioned within a distance to each other sufficient to provide a substantially uniform light beam.
