Abstract: An LED unit is provided with a plurality of LED panels each having a support surface supporting at least one LED. The LED unit may be provided with a frame that may support the LED panels and the arrangement of the LED panels may be movable between a symmetric and an asymmetric configuration.

Abstract: A heatsink for cooling at least one LED may have a longitudinally extending channel flanked on each side by a longitudinally extending column of heat fins.

Abstract: A luminaire and mounting bracket combination is disclosed which allows the luminaire to be readily installed and retained by the bracket while the installer permanently affixes the luminaire directly to the bracket. Single installer capability is therefore allowed due to the construction of the support bracket and luminaire combination described. The bracket incorporates the use of a plurality of support arms and possibly a lower support bracket which correspondingly fit into apertures formed in the luminaire support frame formed on the mounting face of the luminaire. The design allows the luminaire to be vertically lowered on the support bracket and retained thereby while the installer fastens the luminaire directly to the bracket without need for additional support mechanism or aid.

Abstract: An LED unit is provided with a plurality of vertically oriented LED panels each having a support surface supporting at least one LED. The LED panels may be rotatable about a vertical panel axis. The LED unit may further be provided with a frame that may support the LED panels and the LED panels may be removable from the frame.

Abstract: The invention generally comprises a compact luminaire enclosure that preferably contains about 14 to 18 cubic inches of air volume and can be used safely with a 50 watt luminaire. The luminaire enclosure comprises a housing and a shroud that is removably attached to the housing. The shroud has a non-planar face that prevents the shroud from laying flat and trapping heat if the enclosure is placed on or falls on a flat surface. The housing can comprise polyetherimide, which has very good heat dissipation properties. The shroud may also comprise polyetherimide. The compact luminaire enclosure of the invention further comprises an internal thermal lamp shield recessed within the housing. The internal thermal lamp shield comprises highly specular material so that it is able to reflect much of the heat coming from an enclosed luminaire. In one embodiment of the invention, the luminaire comprises anodized aluminum.
