1889 Columbia electric cars to electric light for headlights and tail lights, so light was born. In the same year, the United States Electric Light Company will use parabolic mirrors to the car's headlights, side lights and tail lights. Mainly refers to the light car headlight assembly and rear lamp assembly, they are both features to ensure safe operation of vehicles, but also an indispensable accessories.
1. Car type and function of light
Divided according to use of car lights and signal lights two categories. Divided into light and outdoor lighting lamps and lighting within and outside lights that headlamps, front fog lights, license plate light, dome light inside the lighting means Peng, instrument lights. Signal is also divided into external and internal signal lights, outside lights that turn lights, brake lights, tail lights, showing the wide-lights, down lights, interior lights indicator refers to the dashboard, there are steering, engine oil pressure, charging system dynamic, closed tips and other instruments light.
Car headlights, also known as the headlights, there are two functions, one is light, one is decorated. Past and present, the main functions of headlamps lighting. In the future, I believe it will remain the primary function of lighting. But in recent years, the headlights have continued to transform appearance, and body inlay portfolio as a whole, more and more reveals its decorative effect. In the next few years, you may find that the inner structure of headlamps will also be a major technological revolution occurred, lamps will be fitted with "head" into "smart" light.
2. Related to the operational safety car lights
Car headlights, it is important to protect the safe operation of vehicle parts, one of the light shining headlights farther, the better the light distribution characteristics, the safety performance of vehicles running higher. With the development of automotive technology, car headlamps have changed a lot. In modern cars, in the past that may be loading and unloading of incandescent bulbs and incandescent headlamps are the vacuum has been eliminated, but instead, halogen headlamps, a few years swept the world effort to become the main national car headlights.
Lamps in the car, there is a mandatory inspection of the lighting outside lights and outside lights, because this is a key component of traffic safety. In addition to the license lights outside lighting, the main role is oriented to provide road lighting truck drivers, under certain circumstances can also play a role in the signal, such as flashing headlights when passing to show each other attention. External signal is to facilitate identification of other drivers and determine the contours of the car and set the car trend. Turn signal and brake lights which is a very important signal light, which for automotive safety is at stake. To further enhance security, in recent years have engaged a deputy car brake lights - high brake light, placed in the position after the wind shutters in order to attract people's attention.
Automotive lighting system focuses light headlights, the car-producing countries have their strict standards. Which are American-style with optical light distribution (SAE method) and the European light distribution (ECE way), the former is far from the light reflected by the mirror to the road, which is set before the bulb filament with Guangping blocked the lower part up to the beam by mirror reflection and then fired at the road. The similarity between the two beam method, the Europeans believe that the elimination of other stunning ECE way more effective. Car design has been in accordance with the relevant regulations and industry standards, full account of the requirements of illumination and light distribution, even before the factory tuned to ensure a rigorous standard lighting. Present a general increase in speed, for improving the brightness and color temperature headlamp, xenon lamp power is small because only 35 watts, brightness 50% higher than ordinary halogen lamps, color temperature to 6000K, close to the sun's light color, life and than halogen Light long, there have been numerous high-class cars with xenon lamps instead of halogen lamps.
Outside lights in the headlamps and the technical performance, manufacturers must follow the relevant laws and criteria. For example, standards for car show width light is indicative outline of the lamps, the car front and back of the tube with two lights, in front of the display width of the light color is white or orange, the back was red. Front turn signal light color is orange, the back light color is red or orange. Brake lights and tail lights must be red, white reversing lights. Front fog lamps to give the car drivers to see road use, use yellow lights, as a long wave of yellow fog penetration is better, then fog is used to give warning of his car, said in front of a car, be sure to red. According to the different uses of light have different power and importance, such as taillights, license plate light bulb is generally 5 to 8 watts, brake lights, turn signals, rear fog lamps and more is 21 watts, 50 watt halogen headlight beam beam 70 watts, 50 watts front fog lamps, etc., so the use of cars according to different uses of light have different light color and brightness, absolutely can not be confused.
As the light on an important role in vehicle safety, therefore, all countries have strict regulations. The lights to change the traditional way, first to study regulatory issues. To this end, Europe has organized a car manufacturer (eg BMW, Rover, Mercedes-Benz, Volkswagen / Audi, Ford, Volvo, Renault, Peugeot, Citroen), lighting systems suppliers and lighting manufacturers to join in the work of the group research design to enable the lights to have more freedom, gradually becoming adaptive lighting, and to propose new legislation proposals. Currently, the company has been conducting tests on different samples, and some smart-like headlamps have been installed in the new car.
