The development of LED flashlights has been nearly ten years old. It is divided into three camps, which are vertical structures represented by Osram, flip-chips represented by Philips Lumileds and Jingke, and represented by Yiguang and Liteo. The dress structure. Subsequently, Taiwan's crystal power, the new century, etc. have also rushed into the supply chain of high-profit LED flash. Some domestic packaging manufacturers are also targeting this fertile emerging market. In the past two years, LED flash series products have been launched, and the performance of LED flash lamps has been continuously improved from the brightness enhancement of flash lamps and the full spectrum of high color rendering.
As the only company in China that can mass-produce “no gold wire package†products and has been in mass production for three years, Jingke Electronics has taken advantage of its own flip-chip welding technology and “no package†R&D experience to cut into the LED flash market in 2012. At the end of the year, a white LED product specially designed for flash applications was introduced. The flash LED light source “Easy Flash E-Flash LED†has been updated to the third generation.
| The technical parameters of the EFG series are: | |
| Pulse current: 1000mA | Limit pulse current: EFG@1500 |
| Color temperature (K): 5000-7000K | Luminous flux (Lm): 280-360 |
| Color rendering index: 70 | Forward voltage (V): 3.0-3.6 |
| Illumination angle: 130° | Quality certification: RoHS certification |
Product specifications are as follows:
Compared with the LED flash products with a large number of formal and vertical structures currently on the market, the flash LED light source packaged with a gold-free ceramic substrate has many advantages:
1, the chip thrust can reach 2000g or more, with higher reliability;
2. The electrical connection surface is a metal interface, the thermal conductivity is high, the thermal resistance is small, and it can withstand large current impact;
3, no gold line obstruction, high light color consistency, more uniform light;
4, no gold wire packaging technology to achieve small size, ultra-thin packaging;
5, high brightness, instantaneous output brightness up to 300lm.
“The biggest feature of the mobile phone flash is that it can use 1.5A high current to achieve instant ultra-high brightness. From this aspect, using flip-chip soldering technology to make the flash, due to the elimination of the gold wire, the electrical connection between gold and gold It has demonstrated high-quality reliability in the case of withstanding large currents, and the phosphor is flat-coated, which makes the light output more uniform.†Wei Keen, director of Jingke Electronic Products, introduced. Compared with the traditional package structure, LED flash products packaged without gold wire packaging technology can give full play to the advantages of LED. The Easy Flash series of flashlights will provide an efficient, high-quality product for digital products and intelligent transportation systems for a variety of applications.
However, the promotion of domestic LED flash products is not easy to go, because this market is mainly dominated by four major manufacturers such as OSRAM, Philips, Yiguang and Samsung. It is difficult for domestic LED companies to enter the supply chain of mobile phone manufacturers. Moreover, domestic enterprises have a relatively short development time in this respect, and LED flash technology is still continually exploring and upgrading. This market for both domestic companies, challenges and opportunities coexist.
In this regard, Wu Guofeng, the person in charge of Jingke Electronics, said, "The flash requires high performance, stability and reliability, and at the same time, it must consider the matching with optical lenses. These have put forward many requirements for developers, but thanks to Jingke Electronics With years of accumulated experience in welding technology and close cooperation with customers to establish business relationships, Easy Flash products are very popular on the client side."
“As the shipments of smartphones and tablets continue to rise, the demand for LED flashlights continues to increase, and the profit margin is slightly better than the lighting sector. It is a good business growth point.†Weiwei is full of confidence. "Although the current domestic LED flashlight has not yet entered the international mobile phone market supply chain, with the continuous development and maturity of domestic LED enterprise technology, the localization of supply is an irreversible trend in the future." Jingke Electronics will also go all the way. On the road of localization development, and occupy a certain market position. (This article is the electronic submission of Jingke)
