Abstract: A light fixture having a “U”-shaped frame inside a sealed cylindrical housing. Mounted along the center of the face of the frame are one or more LED lamp panels, which include a number of LEDs, some of which may be powered by a back-up source such as an optionally supplied battery for emergency egress lighting. The lamp panels are mounted using a thermal interface material to promote heat transfer from the LED lamp panels to the frame, which in turn radiates the heat into the volume of the housing to enhance cooling. To each side of the LED lamp panels, a highly polished reflector is attached to the frame to focus and concentrate the light while simultaneously shielding the LEDs from heat radiated from the frame. Attached to the obverse side of the frame is a “U”-shaped back cover that forms an electrical enclosure. An optional diffuser may be supplied.

Abstract: A light fixture (2) that has at least one explosion-proof transparent tube (8) having first and second ends, as well as first and second fixture ends (4, 6) attached to the first and second ends of the at least one transparent tube (8). The fixture ends (4, 6) define openings (42) arranged and designed to provide access to the interior of the at least one transparent tube (8). The light fixture (2) further includes a plurality of removable caps (40) arranged and designed to close and seal the openings (42), and a plurality of light emitting diodes (12) arranged and designed to be positioned within the at least one transparent tube (8) and to emit light through the tube (8).
