Analyze the development trend of LED packaging industry

Xiao Bian combined with the development status and trends of LED packaging industry development, that the future development of LED packaging technology is mainly to the following ten trends.

First, medium power has become the mainstream packaging method. Currently, products on the market are mostly high-power LED products or low-power LED products. Although they have their own advantages, they also have insurmountable defects. The combination of the advantages of the two power LED products came into being, become the mainstream packaging.

Second, the application of new materials in the package. Due to the higher and better environmental tolerances such as high temperature resistance, UV resistance, and low water absorption, thermosetting materials such as EMC, thermoplastic PCT, modified PPA, and ceramic-like plastics will be widely used.

Third, the application of chip current density. Will the chip current density exceed 350MA/mm? Development to 700MA/mm? Even higher. The chip demand voltage will be lower, smoother VI curve (low heat), and ESD and VF.

Fourth, the popularity of COB applications. With the advantages of low thermal resistance, good light pattern, no soldering, and low cost, COM applications will be widely used in the future.

Fifth, higher light quality requirements. Mainly for indoor lighting, Jingtai Optoelectronics will use LED indoor lighting products RA to reach 80 as the standard and RA to achieve 90 as its goal. Try to make the light color of lighting products close to the Planck curve. Such light can be uniform and without glare. .

6. The international and domestic standards have been further improved. It is believed that with the continuous improvement of LED packaging technology, domestic and international quality standards for LED products will continue to improve.

7. Integrated packaged light engines have become packaging values. The integrated packaged light engine will become the focus of next quarter's research and development.

Eight, to the power program (high voltage LED). In the future, indoor lighting will pay more attention to quality, and driven by cost factors, the power supply solution will gradually become an acceptable product, and high-voltage LEDs fully cater to the power supply solution, but it needs to be resolved that the chip reliability needs to be strengthened.

Nine, multi-color LED light source suitable for scene lighting. Scene lighting will be the core competitiveness of LED lighting, and the next take-off of LED lighting will need to rely on scene lighting.

Tenth, the demand for light efficiency is relatively reduced, and the cost-effectiveness has become a magic weapon for packaging plants. In the future, indoor lighting will not focus too much on light efficiency, but will pay more attention to the quality of light. With the improvement of packaging technology, the cost reduction of LED lamps has become an alternative to traditional lighting sources.
