LED ceramic PCB is popular
The popularity of cars has become higher and higher, and people’s requirements for cars are not only limited to the ability to run on four wheels. Nowadays, the selling points of soft demand for cars are becoming more and more important, including interior trim, central control, and appearance. Wait, the demand for power has become a relatively marginal demand. Among these soft demands, the first place is the appearance. The first requirement of most people to buy a car is to look pleasing to the eye. It is not difficult to see from the new domestic hot sales represented by Lynk & Co and Wei, the frontier of fashion technology The appearance of the car can make people ignore many hardware requirements. Of course, this is not to say that the domestically produced cars are not well equipped. Its core is related to the youthfulness of the current car group. In terms of the appearance of a car, the major part of its influence on the "appearance" comes from the lights.
The development of car lights has made rapid progress without our knowing it. From the initial halogen lamp to the xenon lamp, to the current mainstream LED lamp, it actually only took less than ten years, let alone the trial. Laser headlights. LED headlights are slowly becoming one of the rigid indicators for people to judge the quality of a car.

Nowadays, LED is an important trend in the development of automotive lighting in the future. I am afraid that no one will take the bar any more. As more and more luxury cars choose to use LED as the headlight source, LED automotive lighting has a general trend. For LED manufacturers with fierce competition and suffering from meager profits, turning to niche applications is naturally the best choice under the circumstances (forced by helplessness). In recent years, smart lighting, agricultural lighting, optical communications, and smart cities have become the application fields that LED manufacturers are busy entering, and automotive LEDs are one of the few blue oceans that can be temporarily maintained in quantity and price. It is not difficult for everyone to find that LED car lights, whether headlights or taillights, are more expensive than xenon lights. The reason for this is the ceramic PCB, the core of LED lights.
Although LED headlights can save energy by 2-3 times than xenon lamps, their light conversion efficiency is not high. Everyone knows that to emit light is to convert electrical energy into light energy. The same is true for LEDs to emit light. % Of the electric energy is converted into light energy and released, so where does the other 70% go? That's right, 70% is converted into heat and then emitted. This is why the heat dissipation of LED car lights has always been a big problem. For LED to dissipate heat, it is necessary to first export the heat emitted by the lamp beads. The closest contact with the LED lamp beads is undoubtedly the thermally conductive substrate, and the best thermally conductive substrate in the world is the ceramic PCB.
Ceramic PCB has the advantages that other PCBs do not have. It has a fairly high thermal conductivity, and at the same time is corrosion-resistant and high-temperature resistant. It is suitable for use in car lights. However, there are not many domestic manufacturers that can mass produce ceramic PCBs, just like OLEDs, but the difference is that ceramic PCBs have been very developed in countries such as Japan, South Korea and the United States. The technology of ceramic PCBs has been used in my country in the early years The blockade has caused my country's ceramic PCB industry to have just started. At the same time, the ceramic PCB used in my country still needs to be imported in large quantities, and the price has naturally risen.
So everyone has to ask again, don't we have our own ceramic PCB? There really are. For example, Stone Ceramic PCB, which is currently leading the entire domestic ceramic PCB industry, has invested a lot of capital in research and development as an early military-to-civilian technology, and finally brought dawn to my country's ceramic PCB industry.
At present, Stoner ceramic PCB has been able to achieve the same level as the international level, but because it is a ceramic PCB produced by our country, we have a great advantage in terms of price. It may be possible to integrate my country’s automotive LED The price of lamps is the lowest in the world, allowing my country's automobile industry to reach a new level.
