Abstract
A lighting system for low temperature environments includes a plurality of light emitting diodes attached to a support member mounted within a refrigeration unit or the like for illuminating contents thereof. A reflector is disclosed adjacent to the light emitting diodes for dispersing the light therefrom. A light transmitting cover overlies the light emitting diodes, and preferably includes non-planar surfaces for dispersing light onto objects within the refrigeration unit. A power supply converts alternating current voltage to a lower direct current voltage for powering the light emitting diodes in a safe manner.
