Chinise High Power Head Light For LX48Q Motorcycle Round Led Headlight

a. Use a special alloy material with a particularly large temperature coefficient to make the filament, so that its resistance changes to several times before softening at high temperature. In this way, the filament itself is a current limiter, and the bulb can be used in voltage-variable terminals. in line

b. Reduce the voltage of the bulb and increase the current, and use a thicker filament with better strength. According to the light-emitting principle of old-fashioned gasoline lamps, a layer of "DU" is plated on the filament, which can greatly improve the actual brightness of the bulb without much power consumption.
