Patent ID: 8860311

Claim:
A lighting apparatus comprising: an emitter unit including: a first housing having an interior region and a top surface formed to include an opening therein, and an emitter including a body portion, a plasma bulb and an emitter heat sink on the body portion, the body portion of the emitter being coupled to the top surface of the first housing with the plasma bulb positioned adjacent the opening in communication with the interior region of the first housing and the emitter heat sink located outside of the interior region of the first housing; a driver unit including: a second housing having an interior region, a driver located in the interior region of the second housing, the driver generating a radio frequency (RF) signal, and a driver heat sink located on the second housing outside of the interior region of the second housing; a coupler connecting the first housing to the second housing, the coupler securing the emitter unit in a fixed position spaced apart from the driver unit; and a cable coupled between the driver and the emitter so that the emitter generates light energy with the plasma bulb from the received RF signal from the driver.
