An LED module (100) includes; an upper housing (120) with in internal cavity (121) and a lower housing (130). At least one light emitting diode (102) is held in the LED module and emits light into the internal cavity, which is emitted through an output port (122) in the upper housing. An optical structure, which may be disk or cylinder shaped may be mounted over the output port and light is emitted through the top surface and/or edge surface of the optical structure. The lower housing has a cylindrical external surface, which may be part of a fastener, such as screw threads, so that the LED module can be coupled to a heat sink, bracket or frame. The light emitting diode is thermally coupled to the lower housing, which may serve as a heat spreader. Additionally, a flange (110) may be disposed between the upper housing and lower housing. |
