International Classification:

F21S 4/00

US Classification:

36224902, 36224906, 36224911

Abstract:

A lighting system generally includes a plurality of electrically interconnected modules. Each module includes a support, circuitry on the support, at least two light emitting diodes (“LEDs”) on the support and electrically connected to the circuitry, and a housing over the support for covering the circuitry. A first LED on a first surface of the support emits light in a first general direction and a second LED mounted on a second surface of the support emits light in a second general direction, which is opposite the first general direction.
