Headlights are introduced.
Headlights, also known as headlights, are lamps installed on both sides of the head of the car, mainly used for road lighting when driving at night. These lamps can be divided into two lamp system and four lamp system two types, of which two lamp system uses two independent light source bulbs through the reflector to achieve the projection of far light and near light, and four lamp system is the high beam and near light separate arrangement. The lighting effect of headlights directly affects the operation and traffic safety of night driving, so the traffic management departments in the world have provided for their lighting standards in the form of laws.
The design and manufacture of headlights is equipped with an optical system composed of mirrors, mirrors and light bulbs to ensure bright and uniform lighting in front of the car, so that the driver can see any obstacles on the road within 100 meters in front of the car. With the continuous development of automotive technology, the types of headlights have also experienced the evolution from incandescent, halogen, xenon to LED lights. At present, halogen lamps and LED lamps have been widely used because of their good cost performance and performance.
Halogen lamp: A small amount of inert gas iodine is infiltrated into the bulb, and the tungsten atoms evaporated through the filament meet and react with the iodine atoms to produce tungsten iodide compounds. This cyclic process allows the filament to hardly burn out and the bulb to not blacken, so the halogen lamp lasts longer and brighter than the traditional incandescent headlamp.
Xenon lamp: also known as heavy metal lamp, its principle is to fill the quartz glass tube with a variety of chemical gases, through the supercharger to the car 12 volts of DC voltage instant pressurization to 23000 volts of current, stimulate the quartz tube xenon electron ionization, produce white super arc. Xenon lamps emit twice as much light as ordinary halogen lamps, but consume only two-thirds as much energy, and can last up to ten times longer.
LED headlights: Use light-emitting diodes as lamp sources, with extremely high luminous efficiency and up to 100,000 hours of service life. The response speed of LED headlights is extremely fast, there is almost no need to replace them during the design life of the vehicle, and the requirements of the use environment are low.
In addition, with the advancement of technology, new headlights such as laser headlights are also applied in some high-end models, providing longer distance and clearer lighting effects
The difference between headlights, high beams, low lights and headlights
Headlights, high beams and low lights are different parts of the automotive lighting system, each of which has a specific function and use.
Headlights: usually called headlights or headlights, are lighting devices installed on both sides of the head of the car. Headlights include high beam lights and low light lights, mainly used for road lighting during night driving to ensure driving safety.
High beam: In its focus, the light emitted will be parallel, the light is more concentrated, the brightness is large, and it can shine to very high objects. The high beam is mainly used on roads with no street lights or poor lighting to improve the line of sight and expand the viewing field.
Low light: emitted outside its focus, the light appears divergent, can shine to a large range of objects near. Low light is suitable for urban roads and other lighting conditions better environment, irradiation distance is usually between 30 to 40 meters, irradiation width is about 160 degrees.
Headlights: generally refers to headlights, that is, including high beam and low light lighting system.
The rational use of these lighting systems is crucial to ensure the safety of night driving, and the driver should choose the appropriate lighting mode according to the actual situation to avoid interfering with the line of sight of other drivers and reduce the occurrence of traffic accidents.
