Abstract
An apparatus and method for increasing operational life and performance of an arc tube or lamp. The method includes operating the arc tube and applying steps to encourage isothermal conditions around the arc tube. In one embodiment of the method, the arc tube (12) is rotated (40/41) during operation. Another embodiment includes directing air (32/34/26) onto the operating arc tube (12). An exemplary embodiment relates to a substantially high wattage HID unjacketed double ended arc lamp (12) operated in a substantially horizontal position, but the invention is not limited to the same.
Claims27
A method of improving performance of operation of an HID lamp comprising:
- a. operating an HID lamp, including an arc tube;
- b. promoting isothermal conditions for the arc tube.
An apparatus for improving performance of operation of an HID lamp comprising:
- a. an HID arc lamp including an arc tube;
- b. means for promoting isothermal conditions for the arc tube.
An apparatus for improving performance of operation of an HID lamp comprising:
- a. A fixture including a support to hold an HID arc lamp with an arc tube in operative position;
- b. a mechanism mountable to the fixture, the mechanism operatively connected to the arc tube to promote isothermal conditions for the arc tube when the arc tube is operated.
An HID light fixture comprising:
- a. a housing, the housing including
- (1) a connection adapted for mounting the housing to elevated position;
- (2) a mount to operatively mount a light source including an arc tube;
- (3) a mount for a reflector;
- b. a mechanism mounted on the fixture to promote isothermal conditions on the arc tube during its operation.
