Headlamps refer to lighting devices installed on both sides of the head of a car for night driving roads. There are two-lamp system and four-lamp system. The lighting effect of the headlights directly affects the operation of driving at night and traffic safety. Therefore, the traffic management departments of various countries in the world generally stipulate the lighting standards of the car headlights in the form of laws to ensure the safety of driving at night. Automobile headlamps are generally composed of three parts: bulbs, reflectors, and light distribution mirrors (astigmatism mirrors). The bulbs used in automobile headlamps include incandescent bulbs, tungsten halogen bulbs, and new high-brightness arc lamps. (1)Incandescent bulb: its filament is made of tungsten filament (tungsten has a high melting point and strong luminescence). During manufacturing, in order to increase the service life of the bulb, the bulb is filled with inert gas (nitrogen and its mixed inert gas). This can reduce the evaporation of the tungsten filament, increase the temperature of the filament, and enhance the luminous efficiency. The light emitted by the incandescent bulb is yellowish. (2)Tungsten halogen bulbs: Tungsten halogen bulbs infiltrate certain halogen elements (such as iodine, chlorine, fluorine, bromine, etc.) into the filled inert gas, using the principle of tungsten halogen regeneration cycle reaction, that is, evaporation from the filament The gaseous tungsten reacts with the halogen to form a volatile tungsten halide, which diffuses to the high temperature area near the filament, and then decomposes by heat, causing the tungsten to return to the filament, and the released halogen continues to diffuse and participate in the next cycle reaction. , So the cycle goes on again and again, thus preventing the evaporation of tungsten and the blackening of the bulb. The tungsten halogen bulb is small in size, and the bulb shell is made of quartz glass with high temperature resistance and high mechanical strength. Under the same power, the brightness of the tungsten halogen lamp is 1.5 times that of the incandescent lamp and the life span is 2 to 3 times longer. (3) New high-brightness arc lamp: There is no traditional filament in the bulb of this lamp. Instead, there are two electrodes in a quartz tube. The tube is filled with xenon and trace metals (or metal halides). When there is enough arc voltage on the electrode (5000～12000V), the gas starts to ionize and conduct electricity. The gas atoms are in an excited state and begin to emit light due to energy level transitions of electrons. After 0.1s, a small amount of mercury vapor evaporated between the electrodes, and the power supply immediately switched to mercury vapor arc discharge, and then switched to the halide arc lamp to work after the temperature rose. After the light bulb reaches the normal working temperature, the power to maintain the arc discharge is very low (about 35w), so it can save 40% of the electric energy.
