High-pressure metal halide discharge lamp and a lighting apparatus using the lamp |
摘要 |
A high-pressure metal halide discharge lamp includes a sealed light-transmitting discharge vessel, first and second electrodes disposed in the discharge space, and a pair of conductive wires connected to the respective electrodes. The sealed light-transmitting discharge vessel has a pair of seals and envelops a discharge space, which has a gas filling comprising rare gas and metal halides. A first electrode with an emitter disposed in the discharge space at an one side is made of a metal having a high melting point. A second electrode without an emitter disposed in the discharge space at the other side is made of a metal having a high melting point. The pair of conductive wires, which are connected to the respective electrodes, are located in the respective seals and extend from the discharge vessel.
