Xenon Headlamp

Xenon type headlamp is adopted to low beam headlamps. Xenon bulbs do not use a filament. Instead, they produce light when a high voltage current is passed between two tungsten electrodes through a mixture of xenon (an inert gas) and certain other metal halides. In addition to added lighting power, electronic control of the power supply gives headlamps stable quality and tone color.

Following are some of many advantages of xenon type headlamp.

• The light produced by headlamps is a white color comparable to sunlight that is easy on the eyes.
• Light output is nearly double that of halogen headlamps, affording increased area of illumination.
• The light features a high relative spectral distribution at wavelengths to which human eye is most sensitive. This means that even in the rain, more light is reflected back from the road surface toward vehicle, for added visibility.
• Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
