Smile on the eighty-one ugly 2016 LED how to change the seventy-two

2016 from the horse's great dedication to the monkey began the drama of the year, did not grab the dedication of LED small partners, I have begun to show their dedication through practical action. After a rest in February to look at all of us, how to continue to play all kinds of technology.

Technology orientation:

CREE released its LED product research and development to achieve new results in the light of the breakthrough, while achieving superior light quality. According to the relevant reports, a single high-power LED devices, in the current 350 mA, junction temperature of 85 degrees C, color temperature 2700K conditions, the test to get the light output of 1587 LM, the optical efficiency of 134 lm/W, color rendering index Ra>90, R9>90. Based on this result, compared with the similar light quality, the same working conditions in the actual LED lighting applications in the mass production of LED, CREE achieved a 25% optical efficiency. This important milestone, combined with CREE's latest SC5 technology platform, will bring LED system performance improvement, cost reduction, improve the quality of light.

Through the data given by CREE, calculate the device power is: 1587 LM lm/W =11.8W; calculate the device voltage: 11.8W/0.35A=33.7V /134. Pay attention to the effect of light at the same time more prominent its color temperature is 2700K, and its display index and the special color R9 value. Because there is no specific photos, I do not know whether the integration of products.

Seoul semiconductor independent R & D 5630 (5.6mm wide x3.0mm long) is considered to be representative of medium power LED, widely used in the field of lighting and IT. The biggest highlight of the launch of the 5630D is its light effect was upgraded using the Seoul semiconductor MJT multi chip technology LED chip, the industry's highest 210lm/W.

According to the U.S. Department of energy in May 2015 issued a solid state lighting (SSL) research and development plan, is expected in 2020, LED will occupy 40% of the U.S. market share of lighting, including fluorescent and halogen lamps. In addition it also predicts that by 2030, more than 88% of the lighting will be replaced by LED, which is the main energy-saving trend. Plan that, in order to achieve this goal, the lighting effect of the finished product needs to reach 200lm/W, LED package light effect needs to reach 220lm/W. In addition, in order to improve the luminous efficiency of LED lighting products, it is proposed to improve the performance of the power supply (power supply makes the LED light efficiency and life expectancy decreased significantly) and expand the application of high voltage LED recommendations.

Improve the efficiency of LED has been one of the industry technology trends, on the other hand is to provide products with color quality, for the end user to bring more experience.

Product end chip

The LED chip is still dress chip occupies most of the general lighting market, its unique high reliability flip chip will increasingly play its expertise in special applications, such as high reliability, and high power automotive lighting lighting market. At the same time, with the development of major chip enterprises join the flip chip (BDO, crystal Tongfang, and enraytek), packaging and application of auxiliary materials producers (solid crystal, solder paste, package support and substrate factory) market and the terminal application into mature (SMT devices), flip chip market share will be more and more.

Product package device

Relying on EMC support good heat resistance, resistance to yellowing, EMC5050 and EMC7070 products will rise to higher power. At the same time, more chips are integrated into the cup, and more and more products will be formed. The future of the following 15W spotlight applications will be more inclined to discrete device program. Device suppliers will be able to reduce production costs through standardization and scale of the product, and the suppliers (lens, PCB and radiator) are more willing to design according to the standard device.

Filament product. The filament is neither a discrete device nor a traditional COB. For an alternative to replace the traditional incandescent light bulbs do, with low drive current, the whole week light performance for high luminous efficiency and application. Filament products have been in dispute, but there is reasonable. From the design point of view, when the chip in the preparation of the filament will be used in multiple series, welding wire more easily lead to failure of finished products. At present, some manufacturers have begun to use flip chip production filament, in order to improve the reliability of filament products.

COB light source has been expected since its birth, and has been loved by many users because of its flexibility. At present, low power COB products will be replaced by EMC5050 and EMC7070 products, and then on the higher power COB products will be subject to thermal resistance. Commercial lighting products are mainly 20W~50W bracket using COB program more lamps. In order to achieve the effect of lighting, there will be a smaller smooth surface, higher light intensity and higher color rendering and color quality products. Part of the enterprise is driving the development of integrated optical engine, to solve the driving efficiency, pulse current and heat balance problem, photoelectric engine will be a good product. The final model could turn into an interchangeable "bulb"".

Developing trend

Finally talk about the development trend of LED bar. After the Spring Festival, the national policy to the real estate inventory, the final realization of Shanghai, Shenzhen prices rising. There is a place where there is a need for a house, the real estate slump or expansion will drive the development of the lighting industry. No matter the price is still the last radiance of the setting sun comeback, LED lighting penetration in Home Furnishing market will gradually increase. Meanwhile, in 2016 as the country's new five year plan to start the year, macro-control policies will be introduced. 2016 is still a new year's Eve, which will help the company's LED display shipments growth. The overall demand is growing
