The structure of automobile headlamp, the headlamp is an important lighting lamp, traffic regulations have requirements on the headlight's luminosity and illumination range, the lighting effect directly affects the traffic safety of you and others. There are two main types of headlamp: enclosed type and bulb replaceable type. Closed type refers to that the bulb, lens and lampshade are integrated to facilitate the mass production of the whole lamp. Most of the square and round lamps of minicars and commercial vehicles are enclosed. Most of the headlights in cars are irregular in shape, which is not conducive to making them into enclosed type. Therefore, the structure of separating bulb from lampshade and lens is used. Car headlight use and maintenance methods, now, the more high-end cars, the more the use of replaceable bulb headlight. The structure of auxiliary lamps is much simpler, most of them are ordinary incandescent bulbs, plus colored plastic lampshade. In the past two years, some imported cars have used colored light bulbs and transparent lampshades on the auxiliary lights. This kind of light looks bright and beautiful, but the versatility of the bulb is very poor. To check the lighting effect of the whole vehicle, the requirements for the headlamp are very simple: enough light intensity and proper projection angle. Lighting is a test item when the vehicle passes the annual audit line, but in daily use, as long as you feel good. The use and maintenance method of automobile headlamp, the lighting effect of headlamp is mainly related to two factors: light intensity and angle. There will be bumps and vibrations when the car is driving, so the lamps and lanterns will be loose and misplaced, which is also a common reason for the decline of lighting effect. The angle of the headlight is adjustable. Most of them are in the front cabin and behind the headlight. They are adjusted by the positioning screw. Some of them are adjusted outside the car or electrically in the car. Without the help of a light measuring instrument, you can park the car on a straight road and start the engine. But remember that the generator must be used to generate electricity to maintain the normal operation of the headlamp. After each fine adjustment of the angle, switch between the low beam and the high beam until you feel good.
