LED lights generally believed that large-scale replacement of the main reasons for not including the two aspects, one LED lamp itself, the quality first, the cost of LED lights. LED street lamp current quality problems mainly in the total luminous flux, luminous efficiency, light failure, heat, color temperature, light distribution, stability, consistency, power supply and other accessories, such as quality of life. LED lights cost performance compared with traditional street several times to several times the gap. The big advantage of LED lights is saving the current theory, long life, environmental protection, promoting environmental protection in the world today appears to be very bright, by the government and industry support.
Bottlenecks to solve only a matter of time
Governments to increase funding for LED industry input and support in the first half of 2009, China's LED industry, the amount of investment as high as
200 billion yuan. Government business high on the research and production inputs will effectively improve the quality of LED products, LED products, reducing costs. December 2009 Cree white LED made 186lm / W in the laboratory light effect, LED chip, increasing the efficiency of LED products energy-saving advantages of making even more prominent. LED lights in the future through new materials and new technologies, LED lights, including the overall quality of light efficiency, light failure, heat, color temperature, light distribution, consistency, stability, the driving source and roads will also be a good solution. At the same time technological advances and mass production will reduce the cost of LED lamps, LED lamps are the existing bottlenecks and gradually get a better solution.
