| 20100240158 | LED LIGHTING WITH INTEGRATED HEAT SINK AND PROCESS FOR MANUFACTURING SAME - A method for manufacturing an LED lamp assembly includes anodizing at least a portion of a surface of an electrically and thermally conductive base, such as an aluminum or aluminum alloy base, so as to form an electrically insulating coating. The base may form a heat sink or be coupled to a heat sink. The anodized surface is chemically etched and circuit traces that include an LED landing are formed on the etched anodized surface. LEDs are electrically and mechanically attached to the LED landing by means of conductive metallic solder such that heat generated from the LED is transferred efficiently through the solder and LED landing to the base and heat sink through a metal-to-metal contact pathway. | 09-23-2010 |
