LED lights VS the tendency of hernia lamp lights?

LED lights for everyone not unfamiliar, it not only energy saving, long life, and environmental protection, color more gorgeous, home decoration is commonly used lamps and lanterns. In automotive lighting, LED has been used for a long time, but up to now, the whole LED lights models were rare. So that we will be confused, LED headlights effect how? Later will become the future automobile headlight development? Introduction

light history from the emergence of the car, lighting is an important topic of the vehicle driving safety. The earliest lamp is incandescent lamp, then appeared a halogen lamp, and then to the xenon lamp. At present the latest scientific and technological achievements is LED lights.

the earliest incandescent lamp to tungsten life, often need to change. Later in order to improve the service life of the incandescent lamp, people joined the halogen bulb substance of iodine or bromine, is often said that the halogen lamps.

what colour temperature is

later, it was found that the inert gases xenon in high voltage can be issued under the excitation of the glare of the electric arc, and can improve the color temperature value of light, let the light similar to the white light of the sun. Through drilling, philips lasted 5 car xenon headlamps. The xenon lamp, with its low power consumption, long service life characteristics gradually replace the halogen lamps.

the scientific name is LED light-emitting diodes, it is not a fresh thing, actually. Leds are used as indicator in many fields. In the field of automotive lighting, because the LED reaction speed, it is first applied to the brake lights on. In order to let trailing behind car drivers know as early as possible in front of the vehicle driving condition, reduce the collision accident. With the development of science and technology, high brightness LED lights have been invented. It is for the LED light become automobile headlight provides technical guarantee.

xenon lamp luminous principle analysis by the starter and electronic ballast xenon gas and sealed in a glass tube of three parts. Stimulate the xenon light need starter will be the car 12 v low voltage is 23000 v high voltage booster, then starter moment will ultrahigh pressure load on the xenon 23000 v. In the process, once leakage, easy to produce high voltage spark, start a fire.

LED light-emitting principle and xenon lamp has the very big difference. LED is a solid-state semiconductor components. Electricity in the semiconductor material, only part of the electricity will be through semiconductor materials circulation, excess energy released in the form of light, so as to directly convert the electric energy to light energy. The brightness of the LED and there is no direct relationship between the size of the voltage and car 12 v low voltage electric can drive LED completely. When the voltage must be loaded into the LED current through the LED, the greater the LED is bright.

illumination analysis at present, a single LED the brightness of the light source is still less than xenon lamp. In most of the automobile headlamp unit, LED only xenon lamp in a supporting role. Even more than high brightness LED also need a set to release it and make it match the brightness of the xenon lamp. And that a group of high brightness LED and calorific value is much higher than the cost of xenon lamp.

but, manufacturer, said by some special electric switching device, LED can emit light of different color temperature. Made up of LED daytime running lights. Can be converted into color temperature under certain conditions, act as fog lamps use.

LED lights future prospects, at present, the LED light as a car auxiliary lamp has been widely used. In many places the LED lights, fog lights, and replaced by other forms of light. However, due to the cost of high brightness LED and cooling has been serious problems in the research and development personnel, LED as the main lighting source of car is still very immature. If you can break through the bottleneck, the car of the future will be the LED lighting field.
