As we all know, LED has become the standard for new-type cars (especially new energy vehicles) in 2018, so LED automotive lighting has broad prospects for development. In view of the fierce competition environment of general lighting, many LED companies have entered the field of automotive lighting.
On June 10th, the "2018 (16th) High-tech LED Industry Summit Forum" held by Gaogong LED was held in the Westin of the Canton Fair. The forum was divided into three special sessions. Among them, in the "warning era of the post-lighting era" special session, He Keping, product manager of Jingke Electronic Lamps Division, delivered a keynote speech entitled "Intelligent LED Headlight Source Solution".
Jingke Electronics He Guiping delivered a speech
"At present, the penetration rate of LEDs in the headlights is less than 10%, or even less than 5%. It is estimated that by 2020, there will be a 21% ratio of LED lighting in far and near light, so the penetration of LED headlights can be said. There is still a long way to go, and there is still a long way to go. The more optimistic is the interior lighting, the penetration rate of LED in the interior lighting has reached more than 80%, and it is expected to reach more than 90% by 2020.†He Guiping said.
With the development and advancement of LED lights, how far will the future lights develop? He Gui said flatly, first of all, we must pay attention to the shape. At present, the shape of the car is getting more and more cool and more attractive, but the space left for the car is getting smaller and smaller, that is, it is compact, so the car light should play the role of finishing touch; secondly, there is a sense of sculpture, the car The lights are not only just lighting, but also attractive; in addition, there will be light words after the lights, which can express people's mood.
"Digitalization and high resolution will definitely become the most mainstream development trend of the future headlights." He Guiping said bluntly, "In the future, digital, high-resolution headlights will be like a smart phone instead of a traditional mobile phone. It will be the basis of an industry development. Instead of turning points, it will bring about earth-shaking changes."
For the car light products, Jingke Electronics has actually had a layout. He Guiping introduced that from 2W to 20W, PLCC series products are in the phase of elimination, and will be withdrawn from the historical stage. The next focus will not be on such products, mainly to reduce costs and achieve product consistency. Better, better stability. At present, Jingke Electronics has two routes in terms of light source: one is EMC and the other is ceramic.
For the headlight source, Jingke Electronics chose two technical solutions. The first is a single crystal solution, based on which the Mono series was introduced. This product uses an aluminum nitride ceramic package chip, which can reach 240lm with a current of 700mA. He Gui said that the light source of the car can not increase the luminous flux by the chip like the illumination source. The brightness is higher and higher when the chip size is determined or the size is decreasing. This is extremely contradictory. This is also domestically produced. One of the reasons why LED light sources are not used in headlights.
The second is the polycrystalline solution (called the PIG solution internally in Jingke). A low beam or a high beam requires only one source to meet regulatory requirements. This series of products has two chips, three chips and four chips. Compared with most products on the market, Jinke Electronics has no gap between the chips of this solution, thus successfully solving the problem of uniformity of light distribution.
In addition, for the headlight source, Jingke Electronics is also actively developing a new product. This product combines the advantages of light source, and at the same time, considering the design of future lamps, it has made modular products, which have various protections. Components. This product can meet the needs of future compact products. For the ADB intelligent headlight source solution, Jingke Electronics can realize all the functions of far and near ends by using more than one thousand LED light sources in 4×4 space. The intelligent module will be mass produced in 2019.
