Cars more than hundred years of the birth of time, is also the era of human ability by leaps and bounds of science and technology. With the electrical era, great changes have taken place in car electronics components but also, one of the most representative is the development of vehicle headlamps and evolution. Early cars were without a headlight? 吗? Whether 1885 Benz developed the world's first carriage three-wheeled vehicles, or in the same year, German gothic at Daimler, invented the first round of car, car early inventors of first consideration is how to make cars quick and stable ahead, rather than light, so they don't have to install a decent car headlights. The world's first car Benz 'number one', from the diagram shows its not equipped with lights. Really reach the car headlights when from the carriage of the transplanted, before the invention of the light - the most mainstream lighting tools Kerosene lamps. Is from the beginning of the kerosene lamp, car headlights began with the development of the electrical revolution gradually upgrade. From kerosene lamps, car lamps are roughly experienced the acetylene lamp, incandescent/halogen lamps, xenon lights, LED lights, and now the most advanced laser headlight, roughly six times. Kerosene lamps era: use period - 1886 When the car was born in 1904, barely have what function, more don't light up. It is said that in 1887, a driver in the dark on the desert of lost, is a farmer with hand lamp to guide his home. This is also known as the earliest lighting on the car. Cars more than hundred years of the birth of time, is also the era of human ability by leaps and bounds of science and technology. With the electrical era, great changes have taken place in car electronics components but also, one of the most representative is the development of vehicle headlamps and evolution. Still want to rely on combustion luminous acetylene lamp time period of use: - 1905 In 1925, although the first incandescent light bulbs will be used for vehicle head lamp models as early as in 1898 was born, but trapped in the service life of carbon filament fragile and motor generator technology not mature, higher brightness and relatively mature and stable acetylene lamp became the vehicle of choice for head lamp into 'new' era of incandescent light bulb use period: 1925 to present although as early as in 1898, Columbia electric company launched an electric vehicle with a tungsten filament lamp. But as previously mentioned, slender filaments is easy to fracture the bumpy road, plus automobile generator volume is too large, the current is not enough, and that's what acetylene lamp can be used to more than 1925 years. Then with the mature of incandescent lamp technology, halogen tungsten lamp was invented in the 1950 s. Due to the common tungsten filament lamp brightness, efficiency is not high and long time use tungsten filament lamp can make black chimney, in order to overcome the disadvantages people invented the halogen lamp, namely through the combination of chlorine and iodine will be two kinds of gas injection cavity bulb, by using the principle of tungsten halogen cycle lamp black body eliminate the phenomenon. It is in use today are still the mainstream of 'ancient' technology. To this, the incandescent lamp time passed a total of 100 years of history. Challenged halogen lamp now, is a has a higher brightness, less energy consumption, more durable new chy-tech technology: the xenon lamp. The upgrade version of halogen headlights xenon headlamps use period: 1992 to present as people pursuit of speed and comfort of the vehicle, endless with halogen headlights technology development to the limit, higher brightness, lower energy consumption, longer service life xenon headlamps technology was invented. Xenon lamp ( 藏) The high pressure gas discharge lamp. Xenon lamp is heavy metal lamp, through the uv crystal the glass tube filled with a variety of chemical gas, inert gases such as xenon, then through the supercharger will car 12 v power supply instantly rose to 23000 v, under the high voltage, xenon will be ionized and in the power between two poles produce light source. In 1992, hela and Bosch respectively issued its first xenon headlamps technology, and published in 1992 ( Chassis, code-named E32) Is the world's first using xenon headlamps models. The second generation of provide for the first time in xenon lamp low beam as the optional LED headlight technology using time: since 2004 although the LED is not fresh, but used car lighting is not so simple. For cars, LED light source ( Not only limited to headlamps) Has the following advantages: energy saving, long life good durability, LED components of small size, compact and easy to decorate and modelling design, fast response speed low brightness decay, and so on. As early as the 2008 LS model was first used as vehicle head lamp, LED headlamp unit from the LED as a head lamp light source. After each vendor start to follow up use of leds, one of the most widely used is LED in broad light. To become the world's first pick up the production model of laser headlight car was born for more than one hundred years, the development of the headlights never stop steps. As an important vehicle technology, the category of vehicle headlamps is an ordinary functional components, is closely related to vehicle design and safety, and other functions, but with the progress of science and technology, the lights will continue the story, let's wait for the new lamp technology bring us more surprise.
