COB: a car had been struggling in the Red Sea "eliminated" products?

COB vehicle is a field of less concern for the industry, because COB itself is a niche market, volume with SMD vary greatly; secondly the vehicle COB is one of the applications of COB, which shows the market of small. So why do you talk about this today?

Online Jun recently visited a lot of car packaging enterprises, got an answer by common consent -- COB is synonymous with low-end car market in about COB products. In order to further interpret the status of products in the market, the domestic LEDinside online access Jun main layout in LED's enterprise, together to understand the real situation of vehicle COB products.

The past darling, now abandoned?

One by one with the breakthrough of low light efficiency, low reliability, serious decay, COB entered the market in 2010, has become the field of commercial lighting market. Subsequently, the mainstream of domestic packaging manufacturers to increase COB investment, resulting in price all the way down, the price advantage is obvious COB. Because the optical quality of COB is higher than that of single high power devices, in 2014 after the rapid penetration of commercial lighting applications market, and become the mainstream of the current solution of directional lighting, and COB in the application of power market has also been rapid popularization.

This year COB has maintained a high growth, data show that in 2015 COB product sales accounted for about 30% of the overall light, while the 2016 COB lighting (including ceramic package /EMC COB products) market size of up to $580 million.

After several years of price after the fight, COB prices gradually stabilized and close to the bottom, at the same time, with high profit space vehicle has become a new blue ocean market COB. For a time many COB manufacturers began to cut into the large-scale vehicle COB market, many manufacturers also because LED market rewarding, but with the car car soon COB good times don't last long, become the main battlefield of the price war.

In this regard, deputy director of the marketing department of photoelectric crystal Liu Zhihua said the car with the application of COB light source in car headlights after market past large shipments, but mainly in the low-end market, but due to the previous COB light vehicle LED products many problems, the market volume has dropped significantly, overseas customers appear smell COB discoloration situation.

But Siu Chi energy deputy general manager Zheng Haibin said, the price is king, he does not agree with this view. The car that COB is installed after the market entry threshold is relatively low, the price competition is normal. For any market, as long as the product standardization stage, can be called the Red Sea market.

The same party deputy general manager Wei Shiquan said, the same party from 2015 October to enter the photoelectric vehicle headlamps COB after the installation of the market, with the increase, more and more enterprises to enter the market, the company realized that the price of the fierce competition, it is an inevitable trend, but also the most eye-catching performance.

But so easy to do after loading COB headlight is not in the imagination, or a certain threshold, in the optical and thermal processing technology to have a certain foundation and special, and high quality aftermarket channels of cooperation, the price is not the only point of competition.

At the same time, Wei Shiquan also said that in recent years, after the loading amount of COB headlamps will be greatly increased, there will be enterprises to join in this industry, this is destined to be in technology, quality, price, service, speed and other factors on the production of business reshuffle, finally left is king, the same we continue to increase the equipment and technology investment in this area, the project started from the customer, follow the customer demand, give full play to the advantages of the same side in the field of COB, we continue to meet customer demand.

"COB said on behalf of low-end automotive, only low-end positioning

As a light source LED mature, has been widely used in lighting, backlighting, display etc.. But used in automotive lighting LED is not many, especially before market. COB is just one of the packaging forms of automotive lighting LED, currently with COB and CSP-COB in COB package lights.

Li Gang said on LEDinside Avenue, semiconductor, automotive lighting COB light source, the luminous flux can be very high, it mainly depends on the size of the emitting area. But COB is a surface light source, does not belong to linear light source, even if the light emitting region of COB around the growth Strip by package limitation, still can not achieve the goal of small size and high current and high reliability.

At the same time because of its many from outside the area of light linear become harmful stray light and glare, not only can improve effective illumination of the road surface, but also destroy the shape of the light intensity distribution and beam projection. Blindly increasing the luminous flux, not only brings the heat problem more serious, serious glare and deformity of the light intensity distribution will be security risks.

So most people in the industry believe that although COB car headlights cost is very low, but the reliability and shape of the light is relatively poor, should belong to the primary products.

In this regard, Crystal Electronics Product Manager He Guiping said that the advantages of COB in the field of automotive lighting is mainly embodied in four aspects: one is the vehicle COB channel package thermal resistance is shorter, smaller, higher reliability is two; COB is the integrated surface light source, a light uniform, no ghosting, with car lighting demand; three is the optical density of COB is high, strong penetrating ability, long distance illuminated objects is clear; four further irradiation COB automotive headlamps, the driver is still driving a wider field of vision in the night, higher safety, does not belong to the low-end products.

The same party deputy general manager Wei Shiquan also said that the car with COB overall price competition, the relative feeling into the edge of the red sea,
