LED reporter Long Zonghui] The 12th High-tech LED Industry Summit Forum was held in Guangzhou Pazhou Canton Fair on September 26-27. At the first theme conference, Zhao Kun, Vice President of Xinli Light Sources The theme report entitled "LED Light Engine Brings Revolution to LED Lighting".
LED lighting is currently dominated by the Red Sea competition, especially for conventional products. The results of random inspections have made the industry very embarrassing. At present, incandescent lamps are gradually withdrawing from subsidies. If LED lighting is just to replace incandescent lamps with such quality, it will seize the market share of traditional lighting.
LED is defined as an electronic product. The market's main requirements include high color rendering, low frequency flash, consistent light color, comfortable light color, and no glare. Of course, there are other requirements, such as electromagnetic compatibility, voltage protection, power factor, heat dissipation, installation interface, and so on.
Compared with traditional technology, AC-DC technology is more energy efficient, lower cost, smaller in size, longer in life, higher in reliability, and better in electromagnetic compatibility. However, the alternating current is periodically changed, so there is a stroboscopic phenomenon when the alternating LED emits light.
Xinli Light Source has two businesses, one is phosphor and the other is terminal lighting, so there is a certain research on optical and electromechanical heat. In order to realize the AC LED, the solution company has developed an AC LED phosphor. When the AC cycle changes, the illuminating powder will change with the delay of the brightness to compensate for the strobe. At the same time, combined with the AC drive technology, it is combined with the AC LED phosphor to achieve the purpose of improving the electrical performance of the lighting device.
The current LED lighting is still in the replacement stage, and many products are developed in accordance with traditional lighting methods, especially the appearance. However, in the future, LED lighting will certainly develop in the direction of smaller and smaller functions and more and more functions. In order to improve the consistency of light color and maximize the design process of customers, the company launched MOTEMS. MOTEMS uses fluorescent film technology, which is different from remote phosphors because it has a shorter distance from the chip, better light efficiency and lower phosphor usage. At the same time, the fluorescent film can be made into various shapes, and it is easy to realize a light engine supporting a plurality of lamps.
At the same time, Xinli Light Source also matches the corresponding drive solutions for customers. In addition to indoor lighting, this solution also supports outdoor dimming products, AC voltage can be 90-260V, light efficiency > 90-120lm / W, color temperature 3000-5700K.
Zhao Kun concluded that the main contradiction in the LED lighting industry is the contradiction between the increasingly lower product price and product quality assurance. LED lighting products will definitely develop towards modularization. As a illuminable electronic product, the miniaturization and intelligence of LED products is a development trend. Cross-border development will lead to the blurring of lighting boundaries. The development of AC LED light engines will accelerate this trend. Through the improvement of materials and processes, AC light engine technology can create high-light quality, cost-effective LED lighting products, to meet the designer's "quality" to the utmost!
