Mastering the LED lighting design of chip and packaging technology
Since white light-emitting diodes ( LEDs ) have reached 15 to 20 lumens per watt since 2000, countries have been actively investing in R&D and manufacturing of LEDs, and relevant marketing, technology appraisal institutions and academics are actively pursuing this. Sex products are decoded to explore their mysteries and business value, and to make negative doubts or explosive forward-looking forecasts.

However, with the shortage of energy, global warming, rising prices of energy materials and other factors, the government has paid more attention to it, which has accelerated the market popularity of LEDs. The second is that with the white backlight of mobile phones being widely used in 2003, blue light excitation fluorescence is established. The value of white LED produced by powder in the market is more important because LED application can achieve rapid response, reduce replacement and design to increase the aesthetics of industrial products, and gradually open up another market application opportunity to stimulate the development of related supply chain manufacturers. Invest.
Although LED brightness performance failed to meet the demand for main lighting in 2003 (Table 1), it has gradually made the world aware of the future of LEDs and the threat to traditional light sources.

According to the prediction of the American Photonics Industry Association (OIDA), even if the LED has reached $10/1000 lumens, it is still a far cry from the $10/thousand lumens for the entire set of bulbs or lamps, especially for color rendering (CRI). The demand, the efficiency of the light source and the market price will be a major issue that supply chain manufacturers must solve together.
Although the application of LED is extremely extensive, and each application industry will face different levels of technical problems, only the design and solution direction is proposed for lighting applications to accelerate the quality and speed of integrated development of the LED lighting industry.
LED lighting supplier leading industry specifications
The matters to be paid attention to when successfully developing an LED lighting product are quite cumbersome and complicated. A trading company with three to five people may bring operating profit, but after the world standard is formulated, it will also increase the threshold and filter. The application of small factories with poor physical fitness, and even because of the popularized cost structure, LED lighting is gradually concentrated in the leading manufacturers of professional technology and professional foundry manufacturing.
Today's major customers are more committed to exploring upstream materials, technology depth and integration capabilities as a standard for evaluation. The depth and breadth of technology developed at each stage will be a must-have for LED lighting to be successfully completed in 2009-2012. Because the standards are not yet complete, the market demand determines the solutions that suppliers can provide.
