Operation Principle for HID Xenon Lamps

HID xenon lamp, the high brightness gas discharge lamp, is a top-class product of metal halide lamp with complicated luminescence theory and process. Under the normal temperature, ultra pure (99.99%) rare and gas xenon (9kg/cm) is put inside and a small amount of specifically proportional metal halides including sodium iodide, potassium iodide, cesium iodide, scandium iodide and a bit of metallic mercury are added in.

When electric are started under the high voltage, accelerated electron collides with vaporous and plasma state metallic ion inside the lamp and then energy level transitions happens; when activated outer electron of ion turns to be in the low level stable state, the characteristic spectrum of this material (e.g. gaseous metal) will be stem out.
