It was learned from the Science and Technology Department of Zhejiang Province that a private enterprise in Zhejiang cooperated with scientific research institutions to successfully solve the heat-dissipation technical problems of high-power LED lighting, which greatly extended the service life of high-power lighting devices such as LED street lamps and tunnel lights, which can reach 5 years. The brightness is basically not reduced. This breakthrough in core technology has enabled China to have a voice in the global LED lighting application terminal market competition. It is understood that at present, the series of LED street lamp products developed by the company have obtained many certifications such as EU “CEâ€, US “UL†and EU environmental protection “RoHSâ€, and the products have entered the European and American markets.
In the process of developing the LED industry, the chip technology of LED upstream has been matured and shaped, and the LED chips with low price and good quality have been able to meet the needs of lighting. However, in the downstream application terminal market, especially for high-power LED lighting devices for outdoor use, there are widespread problems of poor heat dissipation and short service life. In many places, the LED street lights have been installed very well, but the lighting effect is not long. It is getting darker and darker, and some "dead lights" appear in less than half a year. The reason is that the LED is very sensitive to temperature, the higher the junction temperature, the greater the light decay and the shorter the lifetime. The outdoor lighting needs high power, and the heat of the light source is concentrated. In the unit area, if the heat is not effectively distributed in time, the LED light effect will be rapidly attenuated. Therefore, solving the heat dissipation technology problem of high-power LED lighting has become a prerequisite and a key factor for LED lighting to realize the industrialization of outdoor products.
High-power LED lighting devices, concentrated in multi-chip packages, heat is concentrated in small-sized wafers. When a plurality of LED chips are densely arranged to form a lighting system, the heat dissipation problem is more serious. According to thermal management and fluid mechanics, the company has developed a high-efficiency heat-dissipating thermal management system that integrates “chip and heat dissipationâ€, and produces a heat sink with uniform heat and rapid heat dissipation, which greatly prolongs the service life and makes the enterprise produce high power. The LED street light can reach 5 years and the brightness is basically not reduced. This technology has obtained national patents and was included in the national key new product project by the Ministry of Science and Technology in 2011.
Tests from the National Lighting Quality Supervision and Inspection Center show that the luminous efficiency of the high-power LED street light developed by the company has reached 102.8 lumens per watt (102.8Lm/W), which is 46.8% higher than the national access standard, which is more than the US access. The standard is 28.5% higher. It is understood that the 100W high-power LED street lamp is equivalent to about 400W high-pressure sodium lamp (second-generation light source). Under the same brightness, the power consumption is less than 1/4 of the original, and the energy-saving efficiency is as high as 75%. The breakthrough of this heat-dissipation technology enables high-power LED lighting devices to be widely used in the renovation of street lamps, tunnel lights and garden landscape lights, with huge social benefits.
