The noble gas enables the arc s initial strike.
Hid lamp power supply.
Hid lamps have a warm up time of approximately 2 5 minutes.
This tube is filled with noble gas and often also contains suitable metal or metal salts.
Hid warm up phase 1 1 3 burn phase after the warm up phase when the lamp reaches nominal power the lamp current must be.
A power supply for a high intensity discharge lamp is provided wherein the secondary windings of a pair of lamp strike pulse transformers are connected in series with the hid lamp directly across the ac supply the impedance of these secondary windings acting as the only ballast elements of the power supply.
The time to reach 80 of full light power is called warm up time.
We are able to take advantage of the high brightness of the lamp by realizing the industry s first dsp adoption and fully digital power supply technology.
In particular the present invention relates to an hid lamp power supply which provides fast warm up for a cold lamp regulation against line voltage fluctuations and a lamp starting circuit which provides extremely fast restart when the lamp is hot and has been turned off momentarily.
We provide the top drive technology in the industry.
These lighting power supplies for ac type hid lamps were developed for various projector applications.
