To respond to the appeal for the principle of green and sustainable development, Led panel light which are long-lived and energy-saving, have great light quality, simple structure, small volume and especially quick response are becoming the most important piece of cars to guarantee the safe car operation, leading to its quick development and globe spread.
With the quick development and globe spread of LED bean lights, ruling a standard of the usage of LED bean light to cars is urgent. GB 255991-2010”the standard of LED bean light to cars”, a mandatory national standard, is put into force on January 1st, 2012, which strictly rules the requirement of LED bean lights.
When it comes to the part of bean lights, the standard requires that the bean light need favorable heat dissipation, nice electromagnetic compatibility, device for adjusting light and particularly ability to normally work in the freezing environment, which are all the base of request. Furthermore, white light whose chromaticity fits the GB 4795 is highly emphasized but the composition of red light is satisfied lowly.
In terms of LED module, LED light source giving out visible light which keeps super working condition without defects of design and production is urgently demanded. What's more, LED module must fix on an appropriate settled substrate which has great strength and amazing stability.
In order to reach the standard of the usage of LED bean light to cars, scientists make great efforts to solve the severe problems, such as making certain luminance, decreasing consumption and releasing heat, in the improvement progress.
Increasing the number of LED module and adding electricity supplication are the way to make certain luminance of LED bean light, which is the same as the way used to improve luminance of LED panel lights. However, adding electricity supplication leads to reducing luminous efficiency, which means that a huge amount of energy need offering. To make certain luminance but also decrease consumption, scientists utilize a few white Led downlight to take advantage of various properties of grading and form delicate patterns of grading, the principle of which is also used in LED panel light. When it comes to releasing heat, firstly LED module is improving- the tolerate temperature is increasing to 150 c. Secondly glass is used as the material of sealing LED module, which inhibits the degradation caused by heating when LED lights light. Last but not least, the cooling fin and the cooling tube is fixes on the surface of bulb to give out heat produced through white LED lights.
The standard of the usage of LED bean lights to cars is deeply affecting the car industrial and the breathtaking changes is leading to a crazy age of LED bean lights at the same time the usage of LED bean lights provides us with a safe driving condition and a great effort to speed up the green and sustainable development.
