At the end of 2015, China's car ownership has reached 172 million, and continues to show a rapid growth trend. It can be predicted that China's demand for auto parts and after-sales service market will increase significantly in the next few years, and the automotive lighting market also has great potential for development.
Due to the development of LEDs towards miniaturization, the design of headlights is more flexible. From the past, the lighting function has been extended to intelligent matrix lighting, equipped with cameras and sensing systems to enhance driving safety, as a bridge between vehicles and vehicles. The electric vehicle has become the main light source for energy saving purposes. The above is the biggest difference between the LED light source and Halogen and HID (High Intensive Discharge) lamps. The research structure predicts that the penetration of LED headlights for vehicles in 2020 will grow to 3 compared with 2015. Times.
Due to the high price, the LED headlights for vehicles have their first introduction market. In terms of automobile categories, electric vehicles and hybrid vehicles emphasize the characteristics of energy saving and environmental protection. Just as LED light sources meet this demand, in 2020, such vehicles The proportion of the total market size will reach 7%. In addition, LED light source accounts for a relatively low proportion of high-priced car costs, and such models are designed with styling and smart lights, so the proportion of LED imports is higher than that of cheaper cars.
At the time of miniaturization of LED components, the headlights not only provide lighting functions, but also become part of the "face" of the car, and even highlight individual performance, becoming one of the main considerations for consumers to purchase vehicles.
In addition, with the rise of V 2 V (Vehicle to Vehicle) applications, LED headlights also emulate mobile communication software, adding emoji and driver health information to other drivers, and becoming a simple communication tool among drivers. Increase driving safety.
Intelligent LED matrix headlights play a very important role in driving safety. The light source structure is to arrange multiple LED components into a matrix style, and is equipped with a camera module, a sensor and other systems. Each LED has a function of point and extinction, and a matrix headlight will be According to different road conditions, the light beam can be moved according to the surrounding environment or the turning section. When there are more LEDs, the more flexible the area should be adjusted or not, so as to increase driving safety.
Under the above-mentioned additional functions and differentiation design, the LED light source for the headlights will gradually replace Halogen and HID. It is estimated that the LED proportion will exceed the HID lamp by 2020, which is 3 times higher than that of 2015, reaching 15%. .
In terms of research and development, the current direction of LED headlight research and development is mainly the use of fisheye plus LED light source module or LED bulb solution. The increase in the penetration rate of LED headlights in automobile brands has led the lamp manufacturers to actively look for LED manufacturers capable of producing and designing to jointly develop LED lamps.
Representative company
Recently, the company that has received much attention in the field of automotive LED headlights is Ronda Electronics. LED vertical integration factory Longda Electronics this year at the LED Taiwan exhibition, the first publicly announced new business unit products, including high-end applications of invisible light, automotive and train headlights, especially the self-developed LED headlight module, now spans China The high-speed rail market is being tested and is expected to be officially introduced in the second half of 2016. This move can be said to avoid the Red Sea market and open up a new blue ocean.
In the past two years, Ronda's new business units have achieved high-end product technology, and the automotive LED packaging products have taken the lead in passing the AEC Q101 third-party certification. At the beginning of this year, the new LED headlight module has also been introduced into Chinese cars. And the train market.
Ronda's train LED headlight module adopts high-tech optical lens design, which combines the beam angle within 3 degrees, consumes only 10W, and has a central light intensity of 200,000 candelas (candela, cd). It is used in trains and subways. Or high-speed rail headlights only need 6 to 10 groups, one kilometer illumination can reach 5lux, with low energy consumption, high efficiency and stability, etc., can replace the traditional HID headlights. The automotive LED headlight module is designed for the far and near light of a fisheye. The power consumption of the near lamp is only 13W. It is not only energy-saving but also highly luminous, and it can also be improved in overall design and space application.
Mazda 2
Japanese car manufacturers have used LED headlights as an optional equipment when Mazda 2 was first introduced. Mazda 2 entered the market as MY2015car, and its optional LED headlights are very sophisticated, not only equipped with high beam assistant system, but also a wide range of choices and novel design. These headlights are the finishing touch in car design, making the Mazda 2 stand out among the many models.
Mercedes-Benz E-class
Mercedes-Benz headlights also use LED matrix technology, but they named it multi-beam LEDs. In the 2017 Mercedes-Benz E-Class, each of the optional multi-beam LED headlamps contains 84 individually controlled LEDs. This sophisticated intelligent solution enables BMW's new E-Class to provide optimum beam distribution in any driving situation. Each headlamp contains up to 84 LEDs, and the manufacturer can program the system to make the LEDs more useful, which is more powerful than those with fewer LEDs.
