Big package: medium power, COB, high power will be three minutes

If 2013, patch is the mainstream; that in 2014, COB packaging is gradually becoming the mainstream of the market, the total production increased by 20%-30% compared to 2013. Among them, the COB package of ball bubble lamp even accounted for market share of 40%-50%.

The COB integrated light source is chip On board, which is used to connect the bare chip with conductive or non-conductive adhesive on the interconnection substrate, and then wire bonding is used to realize the electrical connection.

Because it has the characteristics of easy to adjust light, glare, high brightness and so on, it can solve the problem of chromatic aberration and heat dissipation.

At present, there are two ways to realize high power LED lighting: one is to single chip high power LED chip package; the other is to use multi chip integrated packaging ().

The former can achieve high power LED by high current drive, but it will be limited by the size of the chip, the latter has a high cost performance, and become one of the mainstream direction of LED light source packaging.

According to the relevant data show that COB has more than 7% in the overall share of China's packaging products, is widely used in street lamps, direct type backlight, lighting and other applications of high brightness high power LED, 27 billion of its demand from 2017 to 2014 18 billion 500 million, compound annual growth rate will reach 13%.

There are international packaging manufacturers predict that by 2017, power, COB, high power output will be about three minutes.

COB in the domestic and foreign enterprises to compete

Since 2013, CITIZEN, SHARP, Philips, Lumileds, CREE, Seoul semiconductor and other international manufacturers have launched a high efficiency, high quality and high efficiency of the new COB in China market. Domestic manufacturers are also not resigned to playing second fiddle ashineon, honglitronic, have continued to expand production capacity and production.

For example, honglitronic, early in 2008 made the first generation COB package with fixed fiber layer. In 2013 the company increased efforts to promote COB products, have launched a "hung" series of COB products.

At present, honglitronic has four fully automated COB packaging production line, the year will be expanded to 8, the monthly production capacity will reach 3000K, leapt to the forefront of the domestic production of products, including custom size and the main push each accounted for 50%.

2015, the state of the country star photoelectric white light device is the direction of the market is more common COB. Nationstar white Devices Division R & D department, deputy director Xie Zhiguo said, because the COB upstream and downstream facilities relatively mature, the price is higher, once the general solution, the possibility of large-scale production increased.

35 years later, COB package will usher in the outbreak, foreign brands will gradually withdraw from the Chinese market. "Si lighting general manager Xia Xuesong said, because from the law of the industry, and the need for a comprehensive resource area, has the advantage, richly endowed by nature and at this stage, COB is facing a process customization demand, the future will certainly become the mainstream direction of domestic lighting market.

As CITIZEN, SHARP and other mainstream COB manufacturers to enter, and now the market is mainly based on their standards prevail, so there is no universal aspect of the problem. Zou Yiming, general manager of the new moon, said the company added 10 production lines in the first quarter, to the second quarter of COB production capacity will reach 15kk/ months.

At this stage, the domestic COB packaging market is still dominated by CITIZEN, SHARP, CREE and other foreign companies, because of its COB light source has the advantages of technology development and brand awareness.

However, with the gradual maturity of COB technology, in the fierce market forced, part of the domestic manufacturers COB packaging devices in performance has been comparable with foreign companies.

Now domestic COB light source in the R9 is greater than zero, the color rendering index is greater than 80 of the premise, the light effect can be done 110lm/W. After entering in 2014, domestic and imported COB technology gap narrowed.

Zou Yiming said that this year, the overall efficiency of domestic COB will be raised on the existing basis of about 10%, more than 120lm/W, in order to better adapt to the current market demand according to the business.

At the same time, domestic COB to a higher cost and service to open up the market, the market share of foreign companies are being compressed. At present, the market circulation of high efficiency COB, about 70%-80% share in the higher cost of domestic COB products.

With the chip prices continue to decline, the price of power COB will also be lowered, resulting in SMD price advantage for COB does not exist, while the standardization of COB will further exacerbate market competition and accelerate the replacement.

The amount or price on application segments

Since 2010, COB has gradually entered the market so far, four years, the price of the brush all the way down, from a few dollars per watt to the current few cents per watt.

Zou Yiming said, COB price, four yuan a year ago, /W, in 2013 the mainstream product price is also maintained at around $1.2 /W, in 2014, put aside foreign companies and Taiwan enterprises do not say, mainland enterprises mainstream COB products priced at about $0.6 /W. "

In the commonly used COB light source products, the proportion of the price in order are: chips, gold, glue and support.

Among them, the chip accounted for more than 50% of the cost of light source, the individual will even close to 70%, the rapid decline in the price of COB, to a large extent depends on the chip price down.

The one or two quarter of 2014 China's market of small white power chip average price decline of 9%-15%, average power chip prices fell 10%-17%, the high-end chip average price decline gradually expanded, the low-end chip average price decline narrowed.

In the first half, the Chinese market LED white chips in the quarter
