Current situation of automobile LED headlamp industry

2020-05-06 15:52:28

With the steady and rising development of China's automobile market, LED headlights are widely used in automobiles, and LED headlights are mainly used for external and internal lighting. The following is an analysis of the current situation of automobile LED headlamp industry.

At present, there are three kinds of light sources in the market: halogen, xenon and led. Halogen headlights are the most common. Now more than 60% of new cars on the market use halogen headlights. The advantages are low manufacturing and maintenance costs, easy to replace, and the disadvantages are obvious, not enough brightness. As a "high-end product", xenon headlights were once popular. High brightness and long exposure distance were its biggest advantages, which were once regarded as necessary by car owners.

However, with the development of industrial technology, LED lighting has gradually become the future trend. Now in the field of home lighting, LED lighting has become the mainstream. The reason is very simple. LED light source trades for better brightness with smaller power, reduces energy consumption while obtaining better lighting effect, and has a longer service life. It can be said that it has more than one stroke. It is the electronization of automobile One of the most dazzling products in.

Advantages of automobile LED headlight system

1. With the advantages of high lighting efficiency, low energy consumption, high reliability, long service life, small size and environmental protection, LED is increasingly used in the internal and external lighting of the car. It has already crossed from the initial less critical automotive lighting applications, such as cabin lighting, parking lights and instrument panel backlight, to the broader applications of headlights and combined taillights. Foreign high-end car manufacturers, such as Mercedes Benz, BMW, Toyota and Ford, have launched LED headlight systems in medium and high-end cars. It is expected that more models will launch LED headlight system supporting models at Shanghai auto show in April 2015.

2. Color is gentle and almost equal to natural light. It is good for human eye recognition and not dazzling. Because the ability of human eyes to distinguish colors is the best in natural background conditions. Compared with halogen lamp and xenon lamp, it greatly improves the recognition ability of human eyes at night.

3. The average life of LED headlamp is more than 100 times longer than halogen lamp, and at least 10 times longer than xenon lamp, even longer than the life of vehicle itself. And the performance is more stable and reliable. Can reduce the probability of failure, without frequent replacement of bulbs, reducing many maintenance costs. And the use of LED lights can save more energy. What's more, LED headlights start quickly. The lighting time is only about 50ms, about 250ms faster than that of tungsten bulb and faster than that of xenon lamp. From the safety point of view, it greatly reduces the occurrence of rear end collision.

4. Energy saving, small current impact. LED headlights are low-voltage start-up, unlike xenon lights, there is no large instantaneous current impact, which has little impact on other automotive electronic products and batteries.

Current situation of automobile LED headlamp industry

In recent years, under the double stimulation of market environment and government subsidies, the capacity of LED upstream enterprises continues to expand, and the industry competition is increasingly fierce. Most enterprises dilute the cost of production by expanding the scale of production, in order to reduce the price in exchange for market share, resulting in the price of LED chips falling. In particular, some LED manufacturers rushed to complete machine procurement before the end of mainland subsidy policy, which accelerated the release of new machine capacity in mainland China, leading to the deterioration of global LED overcapacity.

In 2015, the cumulative output was 391.821 billion, with a year-on-year growth of 26.45%, mainly concentrated in Guangdong, Fujian, Jiangsu, Zhejiang, Anhui and other regions. Among them, the cumulative output of Guangdong Province is 273.944 billion, accounting for 69.92% of the total output of the country, with a year-on-year growth of 43.26%. In 2016, the total number of light-emitting diodes (LEDs) in China was about 470185 million, up 19.99% year on year. With China's LED overcapacity, it is expected that the growth rate of China's LED output will continue to decline in 2017.

Because LED lighting faces the problem of overcapacity, serious homogenization of commodities, and fierce competition, leading to price war among businesses; in addition, as the bottleneck of LED chip patent is broken, the product technology continues to improve, and the material cost rapidly drops, all of which lead to the price of LED lighting products constantly falling.

There is no doubt that the overcapacity and price drop of the upstream LED industry are good news for the automotive lamp industry. Not only is the supply of LED lamps safe and stable, but also the lamp manufacturing cost will be reduced. Therefore, in recent years, the sales volume of LED lamps has been increasing. In 2016, the sales volume of LED lamp assembly in China was 5.736 million sets. It is estimated that in 2017, the sales volume of LED light assembly in China will be about 6.889 million sets. The prosperity of automobile market drives the rapid development of LED headlamp industry. In the future, China's automobile market will maintain a relatively stable development trend, and the demand for automobile LED headlights will grow synchronously.

Development prospect of automobile LED headlamp industry

At present, there are 20 million households with the ability to buy cars in China. China is likely to become the third largest car market in the world, accounting for 6% of the global share, only second to the United States and Japan. By 2025, the scale of China's automobile market will reach that of the current American automobile market. In 2002, China's automobile production and sales volume reached 3.25 million, 4.3 million in 2003, and 5.15 million in 2004. China has become the fastest growing region of automobile sales in the world.

In the next ten years, the competition of automobile market, in terms of its essence, is the competition of automobile electronics. It is predicted that the price of automobile electronic products will account for more than 45% of the total vehicle cost. And the new and intelligent LED lamps are one of the most dazzling products in the international automobile electronic industry. Experts predict that in the next five years, LED lamps in China will develop rapidly, with an annual output value of 1 billion yuan in recent years, and an annual output value of 3 billion yuan in five years.
