Jingke Electronics AC COB White Light Module Light Source Leading High Light Density Era

After several years of development, COB light source technology will enter a new stage of development this year, and the company will turn into a comprehensive cost-effective competition with high quality, high light efficiency and high stability. At the same time, the package gross profit margin has fallen sharply year by year. Enterprises are urgently reducing product costs. The highly integrated and cost-effective AC COB has become an effective means for companies to seek new profit growth points.

Cost reduction and efficiency gains lead to AC COB

AC COB removes the traditional AC-DC switching power supply, and has no traditional components such as electrolytic capacitors and transformers. Therefore, the light source is highly efficient, and it can solve the short board with insufficient power supply life, prolong the service life of the light source, and reduce the product cost as a whole.

"The LED lighting industry has developed so far, the two drivers of cost reduction and efficiency improvement will make the value chain of the whole industry more reflected. The LED industry should form a supplier integrating integrated epitaxial chips, packaged integrated modules or light engines. Xiao Guowei, chairman of Jingke Electronics, believes that AC COB is an inevitable trend in LED development.

In the past year, Jingke Electronics, Hongli Optoelectronics, Xinli Light Source, Meiya Optoelectronics, Zhonghao Optoelectronics, Xinyue Optoelectronics, Tongfang Optoelectronics, Seoul Semiconductor, and Ronda Electronics began to accelerate their product layout in the AC COB field.

In line with the current situation, Jingke Electronics launched the new AC COB white light module light source at the beginning of this year, which is optimized in terms of wire bonding mode and parameters, and the mass production COB light source is controlled according to the shipping standard of 500 rounds of thermal shock. It integrates thyristor dimming components, IC components and temperature control protection on the traditional COB light source substrate. The external rectifier circuit can realize 220V mains direct input and support 180-260V wide voltage amplitude modulation. In addition, the module light source uses a ceramic substrate, which has good heat dissipation performance and high pressure resistance, and can pass the strict European high voltage test.

Flip-chip technology and strong R&D lead the trend of high optical density

As the most mature flip-chip solderless gold-free package technology in China and Jingke Electronics, which is a white-light chip-scale packaged LED, its new AC COB white light module light source introduces the lighting industry into the era of high-light-density density.

Since 2003, Jingke Electronics has been focusing on the breakthrough of flip-chip technology, introducing wafer-level packaging of integrated circuits into the LED industry through gold-free package, and realizing the technology of gold-free packaging on ceramic substrates and metal substrates. The trend of flip-chip gold-free wire packaging has also become the earliest enterprise in China to implement gold-free wire packaging based on flip-chip bonding technology.

Jingke Electronics COB series products are born in mature flip-chip technology, and continue to optimize technology according to market and consumer needs.

Behind the success of Jingke Electronics, there is a strong technical research and development team consisting of several doctors and masters. According to statistics, Jingke Electronics currently has more than 100 R&D technical teams consisting of technicians, assistant engineers, engineers, senior engineers and senior engineers. Among them, 5% of doctoral degree holders and 20% of master's degree or above.

Jingke people adhere to the product philosophy of “Shouzheng innovation, tribute to craftsmen, do the first brand of LED domestic products, achieve more efficient, more obvious, more intelligent”. Based on the self-developed flip-chip technology, through a series of optimization and further Research and realize the continuous development and upgrade of LED chips, integrated circuit chips and modules. And they value user experience satisfaction, such as small current thermal test before shipment, X-RAY test wire is abnormal, in order to reduce the probability of COB use abnormalities on the client.

Multi-dimensional casting of domestic LED light source shining star

It is understood that Jingke Electronics currently has an SMD capacity of 1000 KK/M; a high-power LED product of 12 KK/M; and a COB product of 3 KK/M. The large-scale production capacity of Jingke Electronics directly reflects its strong ability to control the cost of products, and the overall cost performance is bound to be higher than other domestic enterprises.

In addition, Jingke Electronics has been a portable international LED manufacturer since the end of 2014, and has quickly become one of the most important suppliers in its global supply chain. This year, it will continue to deepen cooperation with major international manufacturers. It is expected that this year's production capacity will be 2015. Doubled on the basis of the year.

On the other hand, in order to meet the requirements of some high-end customers for high light efficiency, Jinko Electronics has launched two series of high-efficiency COB light sources. One is a high-efficiency COB light source (Ts 85°C), which shows an index of 80, R9>10 (special color rendering index, ie red reduction ability is greater than 10), which optimizes the heat dissipation structure of traditional aluminum-based COB products and reduces COB. Junction temperature

Second, in order to meet the extreme requirements of high-end customers for light efficiency, 26W ultra-high-efficiency COB with a luminous efficacy of more than 160lm/W is introduced. In the case of the same chip, the luminous flux is increased by 10%.

With the advantages of mature flip-chip technology, the leading position of white-light chip-level packaging, the “artisan spirit” of independent R&D team, and the scale advantage of huge production capacity, Jingke Electronics COB series new products will become the shining star of domestic LED light source.
