Why the LED headlight few headlamps cleaning device? - China lighting network

The author for car all sorts of new things are still full of curiosity, though most knowledge can 'self digestion, self to persuade' - — Such as the engine of the turbo for global emissions requirements;

but the author of non halogen headlamp this was full of doubt. For car manufacturers, car body without any extra things, 'capitalists' is not for welfare, even if a screw is also money, is the cost, so the question here - — Why the era of xenon lamp, almost there will be 'headlamps cleaning device, and the LED headlight graveness instead? Small make up to discuss with you.

what is the LED lamps?

the LED headlight means the headlamps, see clear! Is all the LED light source adopts the headlights. Small make up think most cheap cars now still use ordinary halogen headlamps, better models will use xenon headlamps. 'Lamp factory' in 2008, the audi first use LED on A4 width modulation, first open the LED headlight. After many vendors are starting to follow up, are beginning to use LED in wide light, now Europe or even start legislated for the driving safety, all cars on sale must be assembled LED in broad light. However, all manufacturers to stay on the LED width modulation in this step, and no further innovation.

until the 2010 audi A8 and second generation of the Mercedes CLS, the real meaning of the LED headlight didn't appear in the line of sight of people. Such as the headlight of mercedes-benz CLS used a total of 71 LED, 16 dipped headlights, high beam 8, 13, turn signal in wide lamp 22, auxiliary light two corners, other 10. Small make up think, all the LED lamps are almost all of the features are beyond the existing xenon headlamps.

what's the use of cleaning device for headlight?

headlight cleaning device is in the bottom of the headlights one outlet, can clean the headlight dust and dirt. Generally, some advanced models are have this function.

the car run or light dark at night, the rain and dust will seriously affect the headlamps lighting, led to the driver's line of sight is affected, for road safety, there is a big hidden trouble. So high headlight cleaning system device 'simple' and effectively solved the problem of the headlight last clear illumination. The small make up the investigation, the law in many countries are now making rules, requirements must be installed in the car headlights cleaning system.

guess a brighter LED not to need to 'headlights clean'

the small make up, this is a very widespread that xenon light more light cleaning is the European standard, xenon lamp is gas source, although the brightness is very high, but in a certain amount of dust strong penetrating power of LED lights, work on the xenon lamp dirt easily cause if any light is scattered, so need to wash up xenon lamp and LED lamps do not need. -vice

guess two headlamps cleaning 'mandatory standards are

is not the same as the standard both at home and abroad, LED standard is different also. The small make up the investigation, such as the ford edge in the u. s. , Canada is a xenon lamp configuration, but there is no headlight cleaning device, if China has, is China's mandatory standards.

guess three Chinese GB think not enough brightness can not use 'headlights clean'

in the domestic selling cars, many are GB ( The abbreviation of national standard) Provisions, one of the most famous car is national standard GB7258, all-encompassing differ a list. And if the GB is GB4785 of lamplight, if dipped headlights use specified in the 'flux' more than 2000 lumens of light source, must be equipped to meet the requirements of GB21260 headlamp cleaning device.

so, The project is only small make up the existing data investigation and analysis of speculation) The luminous flux can be thought of as long as the light source of more than 2000 lumens, must be equipped with headlamps cleaning device.

because headlamps cleaning device with low beam lights only, as long as the light source brightness low more than 2000 lumen -- — Must match, or you don't give the vehicle certification, this but cannot be sold; However, is not the standard cleaning device of the brightness of the LED headlamp has no standard xenon headlamps cleaning device order bright, therefore omitted headlamps to clean.

next, small make up whether to test the LED lamps and xenon headlamps which be more bright?
