LED vehicle light sources can be divided into internal lighting systems and external lights. The interior lighting system includes sunroofs, dashboards, backlight buttons, and head-up displays. The exterior includes headlights, sidelights, taillights, daytime running lights, low beam lights, high beam lights, steering lights, third lights, and front lights. Light source status lights.

In recent years, the external lights have become the favorite parts for car dealers. For example, taillights for mid-size cars, LED light sources are often used. Because LED taillights have low power, stable temperature, and long service life, the reaction speed is fast. When the driver depresses the brake pedal, the taillights light up rapidly.

According to Xiao Ruisheng, a senior researcher at the Industrial Technology Research Institute, LED lights have the advantage of saving electricity and save 60 to 70% of electricity compared to traditional halogen lamps. With the development of electric vehicles more mature, the power-saving light source generated by the electric drive can extend the endurance of the car.

In addition, from the perspective of environmental protection green energy, LED lights are mercury-free. In addition, LED lights have high color rendering, white LED high color rendering, can help identify the lamp signal, reducing the driver's risk of accidents and maintenance costs.

In addition, LED lights have a significant increase in driving safety due to rapid response time. Finally, in line with the trend of narrowing space in modern cities, LED lights are lightweight and small, making it easy to add a flexible model for car models and increase the proportion of available space in the car.

However, Xiao Ruisheng also said that LED lights are not without flaws. At this stage, white LEDs still have problems of high cost and reliability. Because of the large difference in the ambient temperature of the car, from 40 degrees Celsius to 120 degrees Celsius, such a huge temperature difference tests the stability of the use of the LED. Moreover, electronic control components are also needed, and there are technical difficulties in terms of power consumption and reliability.

To break through the difficulties and make good products available means that manufacturers must invest more in R&D. The LED lamp module must also take into account the issues of electromagnetic compatibility (EMC) and product certification.

First, LED lighting has the characteristics of energy saving and long life. The market needs products that comply with environmental protection requirements, and the automotive sector, based on safety considerations, therefore requires special product stability.

Second, automotive lighting belongs to the high-margin niche market. With high technical threshold and long certification time, manufacturers spend an average of three to five years before they can enter the original supply chain.

Once it enters the automobile factory's supply chain, based on traffic safety considerations, the depot must ensure that the source of the shipment is uniform. Therefore, the supplier is not only difficult to replace, but also does not have the problem of 3C product supplier price competition. In addition, if you really get the auto manufacturer's approval, orders for new car models will usually be available, and the automotive sector is almost a good business that can be “steadfast”.

Thirdly, the Taiwan factory was laid out earlier on the mainland, and the mainland market can pay attention to the growth momentum of its operations. As Europe, the United States, Japan, and other countries mostly cooperate with their own domestic LED lighting factories, Taiwanese businesses are more likely to place mainland China, and the quality of products is closer to that of international manufacturers than the local LED factories. Can break out in the mainland market.

Fourth, in the regulations section, the automotive LED market has benefited from the EU's stricter requirements for automotive carbon emissions standards. The EU, through its draft law, requires that the average carbon dioxide emissions per kilometer of new cars sold in the European Union must be reduced from 130 grams to 95 grams by 2020. The EU's future regulatory requirements for vehicle emissions will be more rigorous. The proportion of LED lighting used by depots will also increase.

Getting into the car supply chain is not easy. Although it is relatively stable, it is also relatively closed. This is also the reason why it is difficult for domestic manufacturers to attack the mature and even self-contained supply chain of European, American and Japanese automakers. In the absence of a hinterland, Taiwanese merchants were able to seize the opportunity for car use on the mainland by virtue of their early access to the mainland market, technological advantages and relatively low costs.
