A custom LED lighting fixture system has a planar opaque top element and an opposing planar translucent bottom element that can be custom fabricated to take any number of shapes. Upon fabrication of the top and bottom elements into an irregular circumferential shape, for example, a first aluminum extrusion is fitted to the left side, and a second aluminum extrusion is fitted to the left side. The first and second extrusions adapt to the shapes of the top and bottom elements. The extrusions comprise a first channel on the interior surface configured to accept the top element, and a second channel configured to accept the bottom element. A first end cap couples to a first end of the first and second extrusions. A second end cap couples to a second end of the first and second extrusions. An LED strip is operational on an interior surface of the top element.

A dual extrusion system for an LED light fixture comprises a first extrusion and a second extrusion. The first extrusion has a channel shape and dimensioned to enable underground installation. The first extrusion includes a gutter on an exterior surface, used for connecting multiple first extrusions. The first extrusion also includes multiple flanges on either side of the exterior for stabilizing first extrusion in the ground. The first extrusion also includes interior flanges on either side for providing a floor to receive the second extrusion. The system also provides a second extrusion comprising a channel that is placed within the first extrusion. The second extrusion includes free edges extending along a top brim. Free edges hold a plastic cover. The second extrusion also includes exterior flanges for engaging with interior flanges of first extrusion. The second extrusion also has flanges that create a floor to retain LED strips.

An LED floodlight includes a main unit longitudinally formed by extrusion molding and having in one side an opening of a concave groove, and at least one LED unit attached to an inner bottom wall defining the concave groove in the main unit. The main unit is formed on a back side of the inner bottom wall of the concave groove by the extrusion molding and has at least one ventilating duct and open at upper and lower ends. An area having a large heat capacity is provided between the inner bottom wall to which the LED unit is attached and the ventilating duct. The main unit is configured such that the LED unit is turned on in a posture where a longitudinal direction of the ventilating duct defines a vertical direction thereby transferring heat conducted from the LED unit to an airflow going up through the ventilating duct.

An LED light fixture assembly includes an elongated first support member, an elongated second support member spaced from and substantially parallel to the first support member, and a plurality of elongated LED lighting fixtures coupled to and extending between the first support member and the second support member. Each LED lighting fixture includes an elongated structural frame member having a substantially channel shaped support portion, and a mounting portion opposite the support portion. Each LED lighting fixture also includes a plurality of LED light modules secured to and positioned along the mounting portion, and a cover extending along and supported by the mounting portion. The cover is positioned so light emitted from the plurality of LED light modules passes through the cover and away from the mounting portion.

The invention provides a multi-channel plate (100) comprising (i) a plurality of parallel arranged channels (1) and (ii) at least a light source (10) configured to provide light source light (11), wherein a first channel (110) includes a light transmissive part (12), wherein the light source (10) is configured to provide light source light (11) downstream from the light transmissive part (12) and external from the first channel (110) as a first lighting function, and wherein the multi-channel plate (100) includes a second channel (120), configured to provide an additional function different from said first lighting function.

A lighting assembly is provided that includes a light fixture in combination with a support grid such as a drop ceiling t-bar. The light fixture can be configured to use a t-bar as the main form of support. The light fixture can be push-fit onto a t-bar or use a clip to join two or more portions of the light fixture to an installed t-bar. Once attached to the T-bar, the light fixture itself can provides support for a ceiling tile. Various embodiments are provided which achieve a variety of light distributions useful in typical illumination applications. Both recessed and suspended fixture types are achieved in various embodiments which are particularly well suited for LED lighting.

A modular troffer-style fixture particularly well-suited for use with solid state light sources. The fixture comprises a reflector that includes parallel rails running along its length, providing a mount mechanism and structural support. An exposed heat sink is disposed proximate to the reflector. The portion of the heat sink facing the reflector functions as a mount surface for the light sources. The heat sink is hollow through the center in the longitudinal direction. The hollow portion defines a conduit through which electrical conductors can be run to power light emitters. One or more light sources disposed along the heat sink mount surface emit light toward the reflector where it can be mixed and/or shaped before it is emitted from the troffer as useful light. End caps are arranged at both ends of the reflector and heat sink, allowing for the easy connection of multiple units in a serial arrangement.

A modular acoustic baffle fixture comprising a plurality of acoustic sound absorbing panels forming at least part of the structure of the fixture in which the acoustic sound absorbing panels are mechanically and releasably affixed to an internal support structure and which absorbs sound directed to the void formed therewithin. An LED panel and LED driver may be provided and retained by an internal support structure to project light from the fixture.

An illuminated dock board system comprises a plurality of dock board components that each include one or more channels, each channel having a chamber beneath it. A channel cover component may be separably received into the open top of the channel to cover the channel and may be constructed from a low-opacity material to allow light to emanate. An electrical lighting subsystem comprising a light generating component (e.g., an LED strip) at least partially resides in a channel of a dock board component. And fasteners inserted through the channel and the chamber of a given dock board component operate to mechanically fix the given dock board component to a support structure (pylons, joists, stringers, etc.) such that a head of the fastener resides within the channel in contact with the bottom channel surface and a shank portion of the fastener resides within the chamber.

Lighting device (22) for a false ceiling (10) comprising a plurality of T-profiles (14) having respective longitudinal axes (A) and arranged in a square mesh grid (12), in which each T-profile (14) has a lower wall with a width (W) and in which the grid (12) has a center distance (D) between the longitudinal axes (A) of T-profiles (14) parallel and adjacent to one another, in which the lighting device (22) has an elongated parallelepiped shape with a width (W′) comparable to the width (W) of said T-profiles (14), a height (h) of less than 15 mm and a length (D′) comparable to said center distance (D) between the longitudinal axes (A) of T-profiles (14) parallel and adjacent to one another, and in which said lighting device (22) is capable of being fitted directly in contact with the lower wall of a respective T-profile (14).
