Problems solved by technology
If the user restarts the lamp at high temperature, because the metal halide in the lamp cannot start the lamp in a hot state, it needs to be cooled to a certain temperature to start, but the UV enhancer will work, and the UV from the UV enhancer will radiation is waste
This reduces the life of the UV enhancer
In addition to restarting at high temperature, when the lamp self-extinguishes, it needs to cool down for a period of time before restarting, however at this time the UV will continuously trigger the arc tube, the temperature cools down more slowly, and it takes longer to start the lamp

The invention relates to an auxiliary starting mechanism and a high pressure gas discharge lamp with the auxiliary starting mechanism. The auxiliary starting mechanism comprises an auxiliary starting device and a first electrode close to the auxiliary starting device, the auxiliary starting device comprises a transparent outer shell and a second electrode closed in the transparent outer shell, and when the high pressure gas discharge lamp is started, an electric field between the first electrode and the second electrode enables the second electrode to generate electron emission for assisting lamp starting. The auxiliary starting mechanism and the high pressure gas discharge lamp are characterized in that in the high-temperature state of the high pressure gas discharge lamp, the first electrode is far away from the auxiliary starting device. The auxiliary starting mechanism cannot work when the lamp is restarted at a high temperature, and therefore the service life of the auxiliary starting device is prolonged.
Description
Technical field [0001] The present invention relates to lighting technology, in particular to an auxiliary starting mechanism and a high-pressure gas discharge lamp including the auxiliary starting mechanism. Background technique [0002] Ceramic metal halide lamps and quartz metal halide lamps generally require auxiliary starting devices (UV enhancers) to improve the starting performance of the lamps. The metal surrounding the UV enhancer in this lamp retains its shape well even at high temperatures. If the user restarts the lamp at a high temperature, the metal halide in the lamp cannot start the lamp when it is hot, and it needs to be cooled to a certain temperature to start, but the UV enhancer will work. At this time, the UV from the UV enhancer Radiation is waste. This will reduce the life of the UV enhancer. In addition to restarting at high temperatures, when the lamp is self-extinguishing, it needs to cool down for a period of time to restart. However, at this time, U...
