Description

technical field [0001] In the International Patent Classification, the present invention belongs to the subcategory of electric lighting not included in other categories, that is, H05B, and particularly relates to a high-intensity xenon discharge lamp flashlight. Background technique [0002] Xenon lamp is a high-intensity gas discharge lamp with color light and color temperature that is filled with xenon and a small amount of metal halide in a small quartz bulb, and uses electronic ballast to generate arc discharge with high-voltage pulses. The English name is High IntensityDischarge Lamp , referred to as HID lights. [0003] The electronic ballast is actually a power conversion device, and its design complexity is increased due to the special requirements of the HID lamp load on the electronic ballast. The starting characteristics of the xenon lamp are generally as follows: the voltage regulating unit is used to raise the DC voltage of the battery of about 12V to the igni...
