Abstract
A lighting apparatus is disclosed. The lighting apparatus includes an emitter having a plasma bulb and a driver which provides an RF signal to the emitter to drive the plasma bulb. The lighting apparatus may be used for various applications including illuminating plants and organisms in an aquatic environment, growing plants, facility lighting, and other applications.
Claims18
A lighting apparatus, comprising:
- a driver unit which generates a radio frequency (RF) signal;
- an emitter unit coupled to the driver unit through a cable, the emitter unit configured to generate light energy with a plasma bulb from the received radio frequency signal;
- a window positioned below the plasma bulb, light produced by the plasma bulb passing through the window;
- and
- a mounting structure which is coupled to the driver unit, the emitter unit, and the window, wherein the driver unit, the emitter unit, and the window are suspended from the mounting structure.

1 more element
A lighting apparatus, comprising:
- a first unit including
- a power supply which provides DC power;
- and
- a driver unit which receives the DC power and generates a radio frequency (RF) signal;
- and
- a second unit including
- an emitter unit coupled to the driver unit through a cable, the emitter unit configured to generate light energy with a plasma bulb from the received radio frequency signal;
- wherein the first unit is spaced apart from the second unit and the first unit is coupled to the second unit.
