Automotive lighting industry development were reviewed

1 when the car lighting and lighting products to overview the car, lighting lamps and lanterns is indispensable equipment. Automobile lamps and lanterns there are two main functions: one is to provide lighting for car internal and external features, which illuminates the road, traffic signs, pedestrians, vehicles, identification and other obstacles, in addition, back to the car reading, entertainment and other activities to provide lighting; Second, the signal function, give drivers or pedestrians vehicles exist and convey the vehicle status display signal warning function. Automotive lighting device is a component part of automobile electric appliance, it not only directly affect the performance and safety, and improve transportation efficiency, save energy, are quite important to implement the traffic rules, etc. Hyundai lighting involves computer science, software engineering, electronic information, electrical engineering, mechanical, chemical engineering, spectrophotometric colorimetry, physiology, psychology, ergonomics and aesthetics, and so on. It is formed after a variety of disciplines mutual penetration, cross crossover studies. It has its own unique functional requirements, testing technology and computing technology, sui generis. The types of automotive lighting, there is a lamp outside: auto car/low beam in headlamps ( 头灯) , front fog lamps, wide and turn to the curve of the arc lighting lamps, direction indicator lights, side lights, lighting the lamp, door status lamp ( The light up when the door opened only) , puddle lamp, daylight lamp, etc. ; At the back of the car: brake lights (low 刹车灯) , direction indicator light and display vehicle tail lights, down lights, license plate lamp, parking lamp, mirror lamp, car Windows installation of high brake lights, HMSL） , after the fog lamps, etc. ; Automobile internal: meter back light, reading lamp, audio/door/air conditioning and other indicators, internal variable and tonal head lamp, atmosphere lamp all passengers, toilet lamp, internal turn signal, trunk lamp, etc. According to Visteon corporation, the lights a year on average about using time, low beam headlights, 200 hours in headlamps around 30 hours, 200 hours brake lights, tail lights, 220 hours, 75 hours turn signal, 220 hours parking lights, side lights, 220 hours, 200 hours high brake lights, reversing light 25 hours, license plate lamp is 220 hours, turning light 280 hours during the day. 2 car lighting light source and development of automotive lighting lamps and lanterns product development: the development history of automotive lighting kerosene lamps, acetylene lamp, incandescent lamp, halogen tungsten lamp, high intensity discharge lamp ( 藏) Light, LED lamp, as well as the recent emergence of laser, OLED lighting are also developing. 1 LED the application of intelligent tail lights, both inside and outside the car tail lights is an important component of the active safety technology, as well as the pilot important way to communicate with the car. LED light source widely application in rear lights, make the rear lights intelligent range extending continuously. 1) Increase the brake lights area or the brightness of the emergency brake lights. 2) Auxiliary brake signal. 3) Using the new type of electro-optic components implemented with brake function of signal. 4) Can adjust the brightness with the environment of the smart tail lights.
