China's automotive lighting lacks technical support

When encountering two cars when driving, the lights will only illuminate the lane they are driving in, and they will not have a dazzling effect on the drivers of the opposite vehicle. When turning, the car will not turn and the lights will turn “first” to bend the road first... The headlights are not only lighting, but also tools for "conversation" with road systems and equipment on the roads. From the 20th of this month, scholars and industry experts in global automotive lighting research will participate in the first China International Automotive Lighting Forum to discuss automotive lighting technology.

According to Dr. Lin Yandan, Institute of Electric Light Sources, School of Information, Fudan University, we have not paid attention to the research of automotive lighting for a long time. However, automotive lighting is one of the most important parts in ensuring safe driving of automobiles. According to statistics of the Ministry of Public Security, in 2010, there were 3.9 million road traffic accidents in the country, and 60% of accidents were caused by unclear sightlines. The headlights were one of the major causes of accidents. According to an analysis of traffic accidents in the United States over the past 26 years, the Transportation Research Institute at the University of Michigan has found that fatal traffic accidents mainly occur after obstruction of dark sight.

Dr. Lin Yandan said that the composition of automotive lighting is mainly a variety of instrument lighting, combination taillights, reversing lights, front turn signals, reflective lights and other types, Chinese companies almost never on the R & D front lights, combination taillights, to the car Lamps and other important lights. In 2012, the automotive lighting market exceeded RMB 20 billion, which was mainly divided by foreign-funded enterprises. The level of automotive lighting technology in China is very different from that of developed countries. The number of key core technologies with independent intellectual property rights is limited and there are few innovative technologies.

The backwardness of domestic automotive lighting technology also limits the development of domestic automotive lighting standards. At present, China's national standards for automotive lighting can only be determined by some foreign companies, and in the formulation of international regulations, there is little to say because of lack of technical support.

Lin Yandan introduced: “In the past 10 years, at the world’s most authoritative automotive lighting academic symposium, the number of automotive lighting academic papers from China is basically 0, and there are very few Chinese scholars attending the conference.” For example, some German turn-induction lights used in high-end brands and models, German research began in 1999, but there has been no relevant research in China. "Actually, automotive lighting is not only a breakthrough in optical research, but also requires interdisciplinary cooperation in the fields of sensors, communications, microelectronics, intellectual control, electricity, and thermals," said Dr. Lin Yandan. "The forum has now acquired UN lighting and The support of international authoritative organizations such as the Signal and Regulation Department, the International Association of Automotive Lighting Experts, and the International Lighting Committee hopes to promote the attention of the domestic academic community and interdisciplinary cooperation in various disciplines."
