Is the exterior lighting of the car just a light bulb?
Most people think that car lighting is not a light bulb, of course, his light source is equivalent to a light bulb, but today's car lighting is not just a light bulb, it can have the speed of lighting, driving language, atmosphere creation, etc. A variety of functions, its light source has also undergone earth-shaking changes, from the kerosene lamp invented by the car, to the halogen lamp, to the xenon headlights, and finally to the latest LED headlights and laser headlights. The structure corresponding to this is also simplified and easy to repair and more in line with the requirements of modern automobiles. Strictly speaking, automotive exterior lighting solutions include light sources, internal filling, internal auxiliary devices, and some electronic devices such as voltage regulators. Nowadays, a variety of lighting solutions are on the market, including halogen headlights decades ago. Is it just because of cost? Let us talk about the advantages and disadvantages of various mainstream solutions.
"Old and strong" - halogen lamp
Halogen lamp is a variant of incandescent lamp. Its principle is basically the same, but it is a natural equilibrium reaction of sublimation and condensation of tungsten metal by reacting with tungsten sublimation and halogen, which can effectively avoid tungsten wire breakage. Therefore, the life of halogen lamps is longer than that of incandescent lamps. It is also the advantage of halogen lamps. The conversion of automotive exterior lighting from incandescent lamps to halogen lamps has opened the dominance of halogen headlights. However, with the development of modern cars, halogen lamps have gradually become less complex, and his shortcomings include low brightness, high energy consumption, and driving fatigue that is prone to lighting.
"Remember the lens" - HID Xenon headlights
HID Xenon headlights are often referred to by old drivers as rogue lights. They are headlight killers on highways, shaking the eyes of the opposite person in minutes, causing serious traffic accidents.
"Let's come to the top" - LED lights
LED headlights can definitely count as a typical example of the future, and in 2011 the EU forced the use of LED daytime running lights. Within two years, the advantages of LED lighting are more well known, and people are gradually investing more energy to develop automotive LED lighting technology, including "Light Factory" Audi, which first used LED on its own Audi A6 model. Headlights, which have wide color gamut, low energy consumption, and small size and can be freely shaped, are very popular among car designers, and are often used as a plus item in car sales.
