LED Source Adapted for Light Bulbs and the Like
First Claim
1. A light source comprising:
- a housing having an interior compartment enclosed in an outer surface having a heat dissipating surface and first and second LED power terminals that are accessible from outside said interior compartment;
a first LED directly attached to said heat dissipating surface and electrically insulated therefrom, said first LED having first and second LED power contacts;
first and second housing power terminals disposed outside said housing, electrically isolated from said heat dissipating surface, said LED power contacts providing being powered when a potential difference is applied between said first and second housing power terminals;
a first conductor connecting said first LED power contact to said first LED power terminal; and
a second conductor connecting said LED second power contact to said second LED power terminal.

Abstract
A light source and method for making the same are disclosed. The light source includes a housing, a drive assembly, and an LED. The housing has an interior compartment enclosed in an outer surface having a heat dissipating surface and first and second power terminals that are accessible from outside the interior compartment. The drive assembly is located in the interior compartment and electrically connected to the first and second power terminal. The LED is directly attached to the heat dissipating surface and electrically insulated therefrom, the LED having first and second LED power contacts. The housing has first and second housing power terminals disposed outside the housing, electrically isolated from the heat-dissipating surface, and connected to the drive assembly. A first conductor connects the first LED power contact to the first housing power terminal. A second conductor connects the LED second power contact to the second housing power terminal.
