How Does Led Aluminum Substrate Pcb Become The Mainstream Of Automotive Lighting Applications | YMS


How to view LED aluminum substrate pcb to become the mainstream of automotive lighting applications, next, Yongmengsheng professional aluminum substrate suppliers to tell you.

According to the U.S. Department of Energy, LEDs last 20 times longer than conventional light sources and 10 times longer than halogen lamps.Compared with the traditional light source, the output brightness of the LED lamp with the same power is 3-4 times higher than that of the ordinary bulb, which is better than the halogen lamp.

Twice the height is three times the height.The use of LEDs also helps to improve fuel economy and reduce carbon dioxide emissions.Regular bulbs consume 1.2 grams of carbon dioxide per kilometer, while LEDs consume 0.58 grams.

However, the production process LED lighting automotive circuit board project is also more complex.With the increasing maturity of LED lighting technology, the automobile industry has already used LED light source on the dashboard, and the interior environment lighting is already familiar with the road.

And LED lighting gradually occupy brake lights, fog lights, near-light lights, bright lights, fluorescent lamps, adaptive headlights (AFS) applications.Although the application of LED in automotive lighting has great benefits, there are still many problems to be overcome in the system design, which also brings challenges to the design requirements of automotive circuit boards.

Typical automotive lighting structures rely on the body control module to control lighting.The traditional lighting scheme only needs a switch to execute the instructions of the body control module, and the control circuit is relatively simple.Once the LED lighting solution is turned on, the lighting control circuit becomes complicated.

Because the LED color temperature, output light flux and ambient temperature are closely related, the MCU should be used as the control center, according to the ambient temperature and luminous signal real-time regulation of LED brightness, information collected on the LED, feedback to the body control module, add a series of E.

Electronic components such as voltage regulation, signal regulation, temperature feedback, short circuit protection, electromagnetic filter, etc.From the point of view of cost, compared with the driving circuit of traditional light source, the cost of LED structure is higher. From the point of view of system design, the complex circuit increases the risk of the system and also increases the difficulty of fault detection of electronic components.

By improving the integration of LED lighting control module, it not only reduces the space occupied by the chip to the automobile circuit board, but also improves the reliability of the system, reduces the use of components in the circuit, and reduces the system overhead.

The above is the LED aluminum substrate has become the mainstream of automotive lighting applications, I hope to help you.We are from China’s aluminum substrate supplier – Yongmingsheng Electronics, welcome to consult!
