LED lighting will enter the era of 'high luminous efficiency'1

In the past, LED lighting technology was equipped with various heat dissipation materials and even radiators due to its low light efficiency, which made the cost of its LED lighting scheme rise sharply and its volume appear too bloated due to heat dissipation equipment. and the waste that is ridiculed and useless. However, as the saying goes, Moore's law, which changes every 18 months, also affects LED, a semiconductor lighting. LED prospect forecast light efficiency increases by 20 per year according to '2014- 2018, china led industry market and investment strategy planning analysis report of the data display LED chip luminous efficiency every year improve natural 20- 25. If the price remains unchanged, the gross profit margin of LED chips will increase, so it is expected that the shipment volume and gross profit margin of LED chips will double rise in 2014. Forecast, 2014- 2020, china led chip of market scale will a Year 11. The average growth rate of 85 increased, and the demand scale of China's LED chip market in 2020 was nearly 17. 5 billion yuan. LED luminous efficiency breakthrough 300lm/W us Kerui company (Nasdaq: CREE) It is announced that the luminous efficiency of the white power LED laboratory will reach 303lm/W, which is another landmark research and development achievement of Cree after the release of 276lm/W last year. Under the background of pursuing higher heat dissipation effect, two LED light sources of 100LM/W and 300LM/W are also adopted. If you want to achieve the same light output, then the radiator of the LED light source with a light efficiency of 300LM/W can be reduced more, and the total weight of the entire lamp will be lighter. High luminous efficiency brings lighting solutions with smaller lighting products, endows LED lighting design with more flexibility than traditional lighting, and helps lighting designers break through the original thinking limitations and open up design ideas. so as to bring more updated applications. Light Efficiency and spotlight of LED street lamps are equally important. Generally, the important standard for evaluating street lamps lies in their light efficiency. In the bidding for renovation of relevant lighting projects, the level of light efficiency has also become an important factor affecting the success of street lamp enterprises. The quality of street lamps mainly depends on the light effect, which is generally for testing institutions, but the quality of light effect is not directly related to the quality of street lamps. Your light effect is very good, but if your light is scattered, it's no use not being able to shine on the road. It's the key to doing a good job of gathering light and really shining on the road. Light Efficiency's reflection on low-cost lighting products, some merchants now sell low-cost LED, in order to reduce the use rate of chips, in order to maintain brightness and high current, consumers have to pay a higher electricity bill for this kind of LED with large current, while the extra heat generated by large current is only perfunctory with cheap heat dissipation materials. The deterioration, aging and light decay of materials under high temperature, etc. , we can think about the problems encountered in this low-cost LED lamp. Really good LED products should be to make LED chips achieve good lumen efficiency (lm/W) , Good photoelectric conversion efficiency is the right way, which is also the social responsibility and correct orientation of LED operators to popularize LED lighting products.
