Mercury-free discharge lamp |
| 摘要 |
The present invention provides a low pressure metal halide fluorescent lamp. The metal halide fluorescent lamp may have an oblate spheroid cavity discharge vessel filled with an ionizable metal halide surrounding an exciter housing. An exciter within the exciter housing may drive the ionizable metal halide in an inductively coupled electrode-less manner. One or more embodiments may include one or more heat spreaders and/or thermal transfer pipes for transferring heat from the exciter to a surface of the oblate discharge vessel. |

1. A low pressure metal halide fluorescent lamp comprising:
an oblate spheroid discharge vessel filled with an ionizable metal halide surrounding an exciter housing wherein the exciter provides an RF sinusoidal current producing a toroidal-shaped plasma in the oblate spheroid cavity discharge vessel; an exciter within the exciter housing for driving the ionizable metal halide in an inductively coupled electrode-less manner; and one or more heat transfer caps in contact with the exciter and an outer surface of the oblate spheroid discharge vessel. |
