Abstract

The invention discloses a mercury-free energy saving gas discharge lamp of asymmetric electrodes. Asymmetric surface areas of the pair of the electrodes are (100:92-100:98). A current density and a luminous flux can be increased. A starting current and a voltage are reduced in a same period. Duration time can satisfy an automobile gas discharge lamp. According to a nonmerculic gas discharge lamp of the asymmetric electrodes, a light source portion of the discharge lamp is made of quartz glass, the gas which is sealed in a discharge illumination light source and a luminescent material which uses metal halide as a filling material. Two ends of the discharge lamp light source portion are provided with a pair of exposed leads. The two leads are connected with molybdenum foils. One is used to lead an external current and the other one is connected with an electrode subassembly, which form a mercury-free gas discharge lamp. An electrode surface area ratio of the electrode assembly is (100:92-100:98). The electrode surface area ratio in the electrode assembly is (100:95-100:97), which is helpful for increasing brightness of the lamp and has more advantages.

Description

technical field [0001] The invention relates to a mercury-free energy-saving gas discharge lamp with asymmetric electrodes. Background technique [0002] In particular, the asymmetric surface area of ​​the counter electrode should be [100:92-100:98], which can increase the current density and luminous flux, and reduce the starting current and voltage at the same time, and its battery life (lighting) is mainly used in automotive HID Lights are no problem. [0003] The luminescent materials used in the previous HID lamps were metal halides and mercury. However, it caused environmental pollution. Now the use of mercury-containing HID lamps has been greatly reduced. [0004] In addition to causing environmental problems, mercury-containing discharge lamps can cause other problems. At high temperatures, trace amounts of mercury will react with hydroxyl radicals to form mercury vapor, which will evaporate the tungsten electrodes and shorten the life of the lamp. [0005] Therefo...
