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.
