Ten Trends for Chinese LED Packaging Technology
1. Mid-power becomes mainstream package. Currently, most products in the market are large-power or small-power LED products. Despite unique advantage, these products also have inevitable flaws, which generate mid-power LED products, becoming the main package.
2. New material sees application in package. Due to thermostability, anti- UV (ultraviolet rays), low water absorption as well as higher and better environmental resistance, thermosetting materials EMC, thermoplastic PCT, modified PPA and other ceramic materials will be widely used.
3. Chip ultra-current-density applications. The future ultra current density will from 350MA/mm2 move to 700MA/mm2 or higher. Chip is set to require lower voltage, smoother VI curve (low heat), as well as characteristic integrating both ESD and VF.
4. COB to be popularized. With the help of low thermal resistance, good light, welding- free and low cost, COM application will get board popularity in the future.
5. Higher light quality. This requirement is mainly for indoor lighting. For instance, Kinglight will target at the standard of 80, goal of 90 for LED indoor lighting RA, to make the light color of lighting products close the Planck curve, so the light is even and of no glare.
6. International and Chinese domestic standard continues to improve, due to the continuing improvement of LED packaging technology.
7. Integrated package optical engine to be packaging value.
8. off-power solution (high-voltage LED). In the coming years, indoor lighting will pay more attention to quality. And driven by cost factor, off-power solution is set to gradually be accepted; and high-voltage LED to fully cater to off-power solution, but the chip reliability should be enhanced.
9. Multi-color LED lighting to suit landscape lighting which is the core competitive field of LED lighting, and supports the second takeoff of LED lighting.
10. Luminous efficiency relatively declines, so cost-effectiveness becomes the winning strategy for packaging manufacturers. With improved packaging technology, the continuous price falling forms steam for LED lighting replacing traditional lighting source. When LED entering home lighting, cost-effectiveness will get more attraction from customers.
