实现该目标一半将依靠设计外观改进，包括从透镜、外壳的形状等方面。另一半则依靠灯具种类的更替。氙气灯更换为LED大灯，由于氮化陶瓷基板是汽车LED大灯的最核心的材料，故汽车大灯将成为验证氮化铝陶瓷基板的先行者。

Half of this goal will depend on the design appearance, including the shape of the lens, the shell, and so on. The other half depends on the replacement of the types of lamps and lanterns. The xenon lamp is replaced by the LED headlamp. Because the nitride ceramic substrate is the core material of the LED headlamp, the automobile headlamp will become the forerunner of the aluminum nitride ceramic substrate.

为什么必须用氮化铝陶瓷基板？因为LED大灯的工作温度非常高。而亮度跟功率是挂钩的，功率越大，温度越高，再度提高亮度只有通过精细的冷却设计或者散热器件的加大，但是效果并不理想。能够使其达到理想效果的只有氮化铝陶瓷基板。首先氮化铝陶瓷基板的导热率很高，可以达到铝基板的一百倍，其次，氮化铝陶瓷基板还有非常优良的绝缘性，与灯珠更匹配的热膨胀技术等一系列优点。

Why must the aluminum nitride ceramic substrate be used? Because the working temperature of the LED headlight is very high. The brightness and power are linked. The greater the power and the higher the temperature, the better the luminance is. Only by means of the fine cooling design or the enlargement of the heat dissipation device, the effect is not ideal. Only the aluminum nitride ceramic substrate can be achieved to achieve the ideal effect. The first nitride ceramic substrate thermal conductivity aluminum rate is very high, can reach one hundred times the aluminum substrate secondly, aluminum nitride ceramic substrates have excellent insulation, thermal expansion, and even led a series of advantages of technology etc..

汽车大灯行业主要用的基板有三种，铝基板、氮化铝基板、氧化铝基板。

There are three main substrates used in the automobile headlamp industry, including aluminum substrate, aluminum nitride substrate and alumina substrate.

铝基板：金属基板的一种，导热能力比塑料基板高一些，用在汽车大灯的话，需要比较好的散热设计进行匹配，不然的话，结温依然会很高，结温高了就会导致光衰，时间长了大灯的亮度就会急剧衰减。并且散热设计中的风扇散热器等成本会高很多，相对于陶瓷基板来讲还需要多一道绝缘工艺。

Aluminum plate: a metal substrate, thermal conductivity is higher than the plastic substrate, used in the headlight, need good thermal design, otherwise, the junction temperature is still high, high junction temperature will lead to decay, a long time will be sharp headlight brightness attenuation. In addition, the cost of the fan radiator in the design of heat dissipation will be much higher than that of the ceramic substrate.

氧化铝陶瓷基板：应用最广的陶瓷基板，成本较低，导热率比铝基板高十倍左右，按理说作为大灯基板是够用的，现在汽车大灯LED功率从20多瓦特到60多瓦特的都有，人们对车灯最直观的概念就是够不够亮，车企自然会想办法提升亮度，亮度提升了，功率也就上去了，氧化铝基板也就不够用了。

Alumina ceramic substrate, ceramic substrate is the most widely used, the cost is low, the thermal conductivity is about ten times higher than the aluminum substrate, arguably as headlight substrate is enough, now the powerrouyinji.89ix.comreheji.89ix.com shuliji.89ix.com tanhuaji.89ix.com tongfoxiangw.89ix.comtongzhong.89ix.com car headlights from 20 LED to 60 Duowate Duowate are the most intuitive concept of people light is bright enough, car prices nature will try to improve the brightness, brightness increase, power will go up, is not enough of the alumina substrate.

氮化铝陶瓷基板：算是目前汽车LED大灯应用最多的基板，相比氧化铝陶瓷基板而言，导热系数高出10倍，比铝基板差不多高100倍，用于大功率的大灯是再好不过的选择了，而且氮化铝基板的硬度会比氧化铝高很多，同时解决了陶瓷基板易碎的问题。因为现在很多车企换了LED灯之后，产线很多环节并没有换，用氮化铝陶瓷基板的话，能够完美适应之前的产线，为企业节约了大量的开支。

The aluminum nitride ceramic substrate is currently the most widely used car headlamps LED substrate, compared to alumina ceramic substrate, the thermal conductivity is 10 times higher than that of aluminum substrate is almost 100 times higher for high power lamp is no better choice, but the hardness of aluminum nitride substrate will be much higher than alumina, at the same time to solve the fragile ceramic substrates problem. Because now many car companies have changed the LED lights, many links of production lines have not been changed. Aluminum nitride ceramic substrates can perfectly adapt to the previous production line and save a lot of expenses for enterprises.

其实不光是汽车大灯，在汽车上，陶瓷基板的应用有很多，例如各种传感器之中。还有就是智能汽车的各种大功率模块。从现今汽车行业发展足以窥见陶瓷基板的前景有多么广阔了。然而目前国内所使用的陶瓷基板，依然大量来自于进口，国内这一块的生产还是比较薄弱的。目前氮化铝陶瓷基板能够大量批量的也就那么几家，屈指可数。在应用越来越广的未来，供需关系的不平衡必将导致该行业的大量爆发，届时，陶瓷基板将会更加平民化，也会拓展更大的应用领域。

In fact, not only car headlights, in the car, the application of ceramic substrates, such as various sensors. There are all kinds of high-power modules for smart cars. How wide is the prospect of seeing ceramic substrates from the current automotive industry. However, at present, the ceramic substrate used in China still comes from the import, and the domestic production is still relatively weak. At present, the aluminum nitride ceramic substrate can be a large number of so many, few. In the increasingly widely used future, the imbalance between supply and demand will lead to a lot of explosion in this industry. At that time, ceramic substrates will be more populist and will expand wider applications.
