The following figure is the schematic diagram of automobile halogen headlamp. The lamp holder, reflective cup and lampshade constitute the headlamp assembly as a whole, and the halogen bulb is the luminous point in the middle. Advantage is original factory original match, smooth form is good. Disadvantages are insufficient brightness, easy to bad (theoretical life of 500 hours), high power consumption.

　　Xenon headlamps are basically the same as halogen headlamps in terms of the assembly structure. They are all luminous points, which project light through reflective cups. The difference is that xenon lamps are used to increase voltage Settings and ignition and arc stabilizer components and other components (as shown in the figure below).
