First Claim
Patent Images
1. A lighting apparatus comprising:
- a housing;
a window coupled to the housing, the housing and the window cooperating to define an interior region of the housing;
a first light emitter located in the interior region of the housing, the first light emitter including a first plasma bulb;
a first radio frequency driver operatively coupled to the first emitter, the first radio frequency driver generates a first radio frequency signal which causes the first plasma bulb to generate a first source of light;
a second light emitter located in the interior region of the housing, the second light emitter including a second plasma bulb;
a second radio frequency driver operatively coupled to the second emitter, the second radio frequency driver generates a second radio frequency signal which causes the second plasma bulb to generate a second source of light; and
at least one heat sink coupled to at least one of the first radio frequency driver and the second radio frequency driver, the at least one heat sink including a plurality of fins located outside of the housing for cooling the first radio frequency driver and the second radio frequency driver.

Abstract
A lighting apparatus includes a housing, a light emitter located in an interior region of the housing, a driver for the emitter, and a heat sink coupled to the driver. The heat sink includes a plurality of fins for cooling the driver. The apparatus further includes a driver mounting portion having a mounting surface and a side wall. The side wall is coupled to one of the heat sink and the driver so that the plurality of fins of the heat sink are exposed. The mounting surface of the driver mounting portion is coupled to the housing.
