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.
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 line with the current situation, Jingke Electronics has begun to accelerate its layout in the AC COB field last year.
Gaogong LED looked through the data and found that Jingke Electronics has a long-standing reputation in the lighting industry and has been recognized by the industry for more than 10 years. In addition, with the white-light chip-packaged LED family continuing to advance technology, AC COB white light chips bring industry-leading optical density and lumens/element to lighting applications.
In October 2015, Jingke Electronics' new AC·COB·2727 was completed.
It is understood that AC COB 2727 light source 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. . The module light source adopts ceramic substrate, has good heat dissipation performance, and is resistant to high voltage test, and can pass the stringent European high voltage test.
On the other hand, AC COB 2727 light source removes traditional AC-DC switching power supply, electroless capacitor, transformer and other traditional components, the light source is highly efficient, and can solve the short board with insufficient power supply life and prolong the service life of the light source.
In addition, the AC COB light source adopts linear segmented current control and compensation patent technology, ±3% accurate constant current output control IC, and 500V high voltage process technology.
At present, AC COB 2727 products are being patented and have gained good customer reputation.
Evaluation of AC COB 2727 products by some customers
1. “Jingke AC COB has its own characteristics, and the concept of “COB+†is simultaneously launched, which indicates that Jingke is unique in the development of new technologies and new products.â€
2, "Jingke 2727 AC COB module in 3000K, Ra80 specifications, light efficiency of 100~110lm, fully meet the product design needs, is the preferred module light source for medium power tube spotlights."
3, "Jingke 2727 AC COB direct 220V AC drive, truly achieve de-powered, saving the cost of lighting."
4. “Jingke 2727 AC COB is a chip-scale package, which effectively reduces the heat dissipation path and has excellent thermal management. It has higher reliability than the device-level package products that have been mass-produced in the market.â€
5. “Crystal AC COB basically realizes all the performances of traditional light engines, but the light source module is smaller in size and provides enough space for intelligent lighting design, which is one of the future development directions of light sources.â€
6. “Jingke 2727 AC COB dimming is stable. Its designed dimming module has twice the strobe frequency of AC power, which has no effect on the human eye. It is an ideal choice for current mass production.â€
7. "Compared with the sensitive relationship between light engine and lighting company, Jingke AC COB realizes chip-level packaging, and there is no competition relationship with downstream lighting companies. This is a smart strategy for the development of industrial chain."
8, "Jingke 2727 AC COB verified by the company, the reliability is better than the traditional light engine module light source, and passed the end customer verification of the company, its structural novelty has been highly praised by customers."
9, "Jingke AC COB ceramic substrate packaging, product heat dissipation performance, and high pressure resistance, is the best choice for export to Europe and North America and other high requirements."
10. “Jingke 2727 AC COB is a chip-scale package, and all functional components are effectively protected by fluorescent glue, which has obvious advantages in moisture resistance compared with traditional light engine module light sources.â€
Based on AC·COB·2727, it has been well received by customers during the promotion process. Jingke Electronics will bring this product to “contention†for the “Product Innovation Award of the Year†(2016) High-tech LED Golden Globe Award.
Jingke Electronics said, “As LED lighting gradually penetrates into the professional lighting field, COB products will have more application space. The Jingke COB series is aimed at international mid- to high-end application customers. It is expected that this part of revenue will be this year. It will increase by 2 to 3 times and will reach more than 10% in the total revenue of Jingke in the future."
Then, in the final awards competition, Jingke Electronics' AC·COB·2727 can win the championship in one fell swoop, and please invite colleagues in the circle to wait and see!
