Abstract
A lighting apparatus is provided including an array of light emitting diodes (LEDs) disposed on a base. The base is configured to move heat away from the array of LEDs to other portions of the base and further to the atmosphere or an adjacent housing. In one embodiment, a native oxide on the base electrically insulates the base from the LEDs. In another embodiment, a cover is removably disposed over the array of LEDs, and removal of the cover prevents electrical energization of the LEDs.

13. A lighting apparatus, comprising:
-
a base;
an array of LEDs mounted to the base;
a cover configured to cover the array;
wherein power is supplied to the LEDs via an electrical pathway, and the cover is mechanically coupled to the base such that attachment of the cover completes an electrical pathway to permit power to flow to the LEDs, and removal of the cover opens the electrical pathway to prevent flow of power. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
