Upside down COB massive campaign, dress will be saliva drowned?

[Reuters] with the maturity of the formal LED product is getting higher and higher, the difficulty of technology upgrading is getting bigger and bigger, the LED technology in the last few years by the industry gradually sought after LED. Because of its good heat dissipation without gold, but the high cost, COB has become the first to go to the market to flip the brick.

Now flip chip COB has gradually entered the production line of the major packaging companies, the industry is often replaced by the flip upside down will be an inevitable trend, but why is still still a dress oriented? Can you really take a look at the manufacturers?

Upside down upside down is a temporary market

Currently upside down compared to the dress, and not much advantage, the price is almost, market recognition is not enough. And the flip of the two optical is not a good fit, and the brightness is lower than the 10-12%, although the same side of the current photoelectric can do less than 8%, but still face these problems.

Upside down on the current brightness is not enough, the same side of the photoelectric technology director Huang Wenping said that the same price, flip chip size is to go down, so caused a decrease in brightness. But in the same size, the flip brightness is high, after all, it is less positive absorption.

In short, the current price of flip COB and not much advantage, for the time being only a narrow market. But the flip is a trend that will eventually replace the suit, and it will certainly be brighter than the formal one, for both the process and the structure are simplified.

The same side photoelectric: high optical density flip chip COB

Jiangxi Siu Chi photoelectric deputy general manager and marketing director Zheng Haibin also said that some products are relatively mature and formal COB has relatively low cost, make full use of COB flip chip resistant high current and no gold production material cost optimization, provides the conditions of production and management cost reduction, just flip COB market validation time.

In this regard, honglitronic general manager Relinin believes that at present this kind of product market is still mainly at both ends, one is the low price, high light efficiency of product requirements. The other end is a special field of high-end products, such as lighting design space is limited but requires high power and high luminous flux output, the special requirements of reliability and small light emitting surface of high power output and so on, it has its own unique field.

In this regard, Xia Xuesong, general manager of silicon lighting can also said that from the medium and long term, the market share of a large proportion of the flip is inevitable trend. On this point, Zou Yiming, general manager of Shenzhen crescent moon also said that with the flip chip light effect, the price continues to optimize the upgrade, the huge market space in the future.

Flip and dress is not 0 and the city accounted for 1, but will be the mainstream

Inversion is to replace the general trend, but is completely replaced? Elec-Tech chip division vice president Mo Qingwei believes that although the next 1-2 years, COB will start using COB flip from high power and high power in the outdoor industry, commercial lighting has also been launched.

For example, NVC commercial lighting has been basically full turn to flip COB Elec-Tech, small power bulbs should be challenging, but many teams in such direction. But the flip cob will be the mainstream technology, but the relationship with the formal cob is certainly not the relationship between 0 and 1.

In this regard, senior vice president of the Asian market, said Wen Jianhua, flip COB and COB have their own advantages and disadvantages. From the current technology, COB technology and the formal process is more mature, higher efficiency, the current cost control is better; the flip COB can withstand higher drive currents, the optical density is higher, but no formal COB high efficiency.

It is the different characteristics of them, so that they are currently focusing on different market segments, COB dress is mainly used for general lighting and a wide beam angle, flip COB mainly for key lighting and a narrow beam angle. In the expected future, they will play a role in their respective segments. As far as the future, it depends on the development of technology.

In this regard, Luminus vice president of sales China Fang Ning also said that at present the formal COB mainly point to focus on the business environment for lighting, light quality requirement is very high, flip the advantage of COB is that the light emitting surface can be smaller, the irradiation angle can be more concentrated, but the high cost and low efficiency, can not cover the entire commercial lighting the needs of the application.

In the long term, flip COB will be a useful complement to the formal COB in commercial lighting, but will not fully replace the formal COB.

Yin Hui, deputy general manager of optical spectrum, said that a few years ago it was predicted that after the CSP came out, packaging companies will not have room for survival.

LED technology has penetrated into many industries, lighting, backlighting, automotive, agricultural, medical, curing and so on, application determines the diversification of LED package, there are advantages of flip flip, but the dress has a formal market, instead of a part can be fully replaced, is not realistic.
