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.
Hid lamp power supply.
Description of the prior art.
Hid lamps have a warm up time of approximately 2 5 minutes.
We provide the top drive technology in the industry.
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.
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.
The time to reach 80 of full light power is called warm up time.
In figure 7 typical behaviors of lamp voltage and current during warm up is shown.
This tube is filled with noble gas and often also contains suitable metal or metal salts.
Your 1 hid led lighting source.
High intensity discharge lamps hid lamps are a type of electrical gas discharge lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube.
