Jinko Electronics’ high-efficiency COB storm is coming

COB, which once had a high gross profit margin, cannot escape the law of market development. Factors such as the influx of companies, the decline in SMD chip prices, and the decline of upstream materials have caused the price of traditional COB to fall sharply in the past two years. According to statistics, the decline has reached 50%.

With the maturity of traditional COB technology, companies no longer stay at the stage of initial technical solutions. COB products with higher reliability, higher light efficiency, and longer life have become the new trend pursued by companies and are also the best way to escape the price red ocean. Compared with traditional COB, high-efficiency COB products not only improve light efficiency, but also reduce heat loss and thermal resistance, thereby improving product reliability and increasing the light quality of lighting products.

The high-light-efficiency COB storm is coming

Jinko Electronics, which has always pursued innovation and breakthroughs, continues to technically optimize COB performance. At the beginning of this year, it launched several highly competitive COB products, especially its new AC The COB white light chip has been optimized in terms of bonding mode and parameters, and mass-produced COB light sources are controlled according to the shipping standard of 500 rounds of hot and cold shock, leading the industry trend.

In order to meet the extreme requirements of high-end customers for light efficiency, Jinko Electronics has optimized the packaging process and launched a 26W ultra-high light efficiency COB with a light efficiency of more than 160lm/W. With the same chip, the luminous flux has increased by 10%. In addition, the color temperature is 5700K and the CRI is 70.

“Craftsman” Jinko is constantly innovating

It is understood that there are currently not many companies launching COB+ module light sources on the market. The only one with relatively mature technology is Citizen. Jinko Electronics, with its leading advantage in the field of LED flip-chip, is expected to become a national leader. The leader in internal COB+ module light sources; in terms of high-efficiency COB, there are not many companies that can achieve a light efficiency of 160lm/W or more. Of course, international major manufacturers Lumileds and Luminus have taken the lead in achieving mass production in Q1 of 2016, but Jinko is undoubtedly the leader in domestic high-efficiency COB manufacturers.

COB competition is becoming increasingly fierce, and companies are focusing on the optimization of product technology. While Jinko Electronics is constantly upgrading innovative products, it also insists on developing and producing products with the spirit of craftsmanship. For example, small current thermal testing is performed before shipment, and X-RAY checks whether the welding wire is abnormal, thereby reducing the chance of abnormal COB usage on the client side and improving user experience satisfaction.

COB currently mainly follows the route of deep refinement and customization, mainly for high-end commercial lighting applications. However, as COB supporting products mature, it has begun to penetrate into the industrial lighting field, such as industrial and mining lamps, etc., which have widely adopted COB light sources. The COB application market continues to penetrate and expand, and Jinko Electronics' innovation in the COB field will not stop. He Guiping said that Jinko will optimize COB products in three aspects in the future. "First, the COB brightness in Q4 of 2016 will increase by 10% compared to Q1 of 2016; second, it will achieve 2-step color tolerance shipment; third, it will achieve mass production of 170lm/W COB light source in the fourth quarter of this year."
