With the iteration of the lighting technology, the interior design of the headlight is becoming more and more important. Today, LED lights have become an integral part of the identity of the luxury brand (do not confuse with the Japanese Light).
This is because early halogen lamp is an incandescent lamp, it relies on is incandescent and halogen gas of chemical reaction to produce a light source. This principle determines the structure of the interior of the lamp bowl is basically fixed, in addition to the installation of a lens, there is no plasticity and can be decorative.
Later, the gradual popularization of xenon lamp (HID), it is a cold light source, compared to the halogen lamp, xenon lamp is smaller, less energy consumption, radiation distance farther. The xenon lamp is used to activate the electronic light, so do not need the tungsten supplies, longer service life.
Xenon lamp headlight assembly is provided with a ballast of parts, it can in a moment of turning on the power supply of the 12V voltage is increased to 2.3 million V, using super voltage activated inside the tube xenon iodide and other inert gas, to produce light source. This principle is the same as the halogen lamp, so the light source also has the same scattering. In this regard, xenon headlights are generally equipped with a lens to focus the light.
However, from the beginning of xenon headlights, the volume of the light source is reduced a lot. So in the design, the designers play a greater space. The most important, some of the features of the headlight is also more abundant. For example, far and near light automatic adjustment, with the move to the level of regulation, so that the user experience to enhance the headlight.

Next is the focus, that is, LED and laser headlights. Say first LED. As a gradual popularization of a lighting technology, LED technology from the field of consumer electronics to the automotive field gradually infiltrated. In the 2015-2016 years of the car industry during the iteration of the tide, the new generation of models equipped with LED headlights accounted for a high proportion.
It can be said that this wave of new wave of the LED lighting technology has officially confirmed the popular trend. Several representative models including the new BMW 7 series, Audi, Volvo, Lexus RX S90 A4 etc.. And Mercedes Benz from 2014 began to gradually update product series, from the new C-class started on line comes standard with a LED light source (dipped beam and high beam is still a halogen).
Compared with xenon lamp, LED lamp light source is smaller, which means that the designer can be in the light body to expand the rich imagination. With the popularity of LED lights with decoration strip, far and near light lamp light source also appeared in the amazing shape, is the most impressive Mo too Lexus diamond matrix design.
LED technology in the daily light, wide lamp, brake lights on the application has been more widely, but in the headlights also belong to the rare configuration. Like the Infiniti Q50 such vehicles, equipped with the LED for its many points. Of course, the headlights still like Benz halogen. Lincoln MKZ further, the direct use of the LED far and near light design.
As an application has been a very wide range of light source, LED into the car headlight is not accidental. 5 years ago, with full LED headlamps light source models are very rare. With the engineering personnel to overcome, the LED lamp source radiation distance and physical spectrum penetration ability has been improved, in compliance with the application of the vehicle level scenarios.
