Abstract

An LED assembly for illuminating a refrigerated area includes a plurality of LED modules and a reflector base configured to reflect light generated by the plurality of LED modules into the refrigerated area. The reflector base is further configured to conduct heat away from the plurality of LED modules and also includes a base cooling channel. Both the reflector base and the plurality of LED modules are located substantially within the refrigerated area. The LED assembly also includes an external heat sink coupled to the reflector base, and configured to conduct heat away from the reflector base, wherein the external heat sink is further configured to be mounted substantially outside the refrigerated area. The LED assembly can include a doom lens that forms a doom cooling channel substantially enclosing the reflector base. This internal heat sink includes an internal sink cooling channel.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This is a continuation-in-part application of U.S. application Ser. No. 11 / 670,981, filed on Feb. 3, 2007, pending, and entitled “Light Emitting Diode Modules for Illuminated Panels”, incorporated by reference in its entirety; and co-pending and concurrently filed application Ser. No. ______, (Attorney Docket No. IM 0702) filed Mar. 29, 2007, entitled “Light Emitting Diode Waveguide Assemblies for Illuminating Refrigerated Areas”, by George K. Awai, Michael D. Ernst and Alain S. Corcos, which is incorporated by reference herein for all purposes.BACKGROUND OF THE INVENTION[0002]This invention relates generally to illuminating panels. More particularly, this invention relates to light emitting diode (LED) modules for illuminating refrigerated areas.[0003]Refrigerated display areas, such as supermarket freezers, make use of interior case lighting to illuminate products and to attract shoppers. In addition, the lighting should generate minima...
