On June 10, 2014, as the global leader in silicon substrate LED technology, Wei Chenyu, the head of Jingneng Optoelectronic LED Flash Project, first released the use of silicon in the 2014 New Century LED Summit chip, packaging technology and modular specialization. The mobile phone flash of the substrate high-power LED chip, and shared with the participants the advantages of the high-power LED chip on the silicon substrate applied to the flash lamp and the future development trend of the LED flash.
The high-power LED chip of silicon substrate has the unique advantage as the light source of mobile phone flash: the high-power LED chip of silicon substrate is a vertical electrode structure chip, which can withstand high current and high reliability, and meets the requirement of large instantaneous working current of mobile phone flash; The surface light is good, the directionality is good, there is no extra side light affecting the working state of the camera, which causes glare; more importantly, the silicon substrate LED chip is suitable for the direct coating process of the phosphor, so that the color uniformity of the light source is better. The effect of taking pictures is better, no halos, spots and other phenomena.
At present, the mainstream package of LED mobile phone flash is ceramic package for high performance. Thanks to the advantages of crystalline silicon chip LED light source and leading ceramic packaging technology, the LED mobile phone flash has achieved 320Lm ultra-high brightness, /-350K ultra-narrow color temperature range and CRI85 excellent color reproduction. Expressiveness and performance are superior to the performance of mainstream products from foreign manufacturers.
In the future, LED mobile phone flash is not only a comprehensive cost and performance contest, but also the interaction of LED light source manufacturers, mobile phone manufacturers and mobile phone users. It is the value of comprehensive solutions. As the global smartphone market continues to grow, the market share of Chinese branded mobile phones has increased significantly year by year. Jingneng Optoelectronics aims at the huge market prospect of mobile phone LED flash. The advantage of using the light source of silicon substrate LED chip is applied to the advantages of mobile phone flash. Combined with precision drive and Lens design and processing, it provides customers with a complete set of module solutions for mobile phone flash. It also provides a more superior camera experience for mobile phone users. This is the difference in the crystal flashlight market.
