White LED lamps used in indoor lighting gradually become climate

With the continuous advancement of LED technology, LED is gradually from the signal display, stage of development to the lighting application stage, long lifetime, high efficiency and energy saving features have been recognized, application of white LED opened a window of white LED green lighting "is indoor lighting category being more and more widely. White LED many advantages of using white LED in indoor lighting has many advantages. First, the brightness and color of the LED can be adjusted to meet the requirements of the indoor decorative lighting on the color, in the development of the scene lighting market, with the advantages of traditional light can not be compared. Second, LED to dynamically control, cluster control can be preset according to the needs of users, in need of some programming skills of the occasion, can provide a reasonable solution, for the intelligent management of indoor lighting to provide convenient. Third, LED small size, more decorative features, through the lamp can be integrated with the building, to achieve "see the light" effect. Fourth, LED long life, mercury free, in line with national policy of energy saving and emission reduction. In fifth, LED is definitely the beam angle in directional radiation, used for lighting, lights and lamps, is conducive to the improvement of downshot flux ratio. Decreased with the enhancement of LED technology, to show the effectiveness and cost saving, both in the international market or the domestic market, LED has begun to enter the commercial lighting department or home lighting market, showing a good momentum of development. In indoor lighting applications widely at present LED price is still very expensive, but because the LED lamp has high light efficiency, can save power consumption cost, and long life, can reduce the replacement and maintenance costs, therefore, in consideration of the white LED lighting development direction, compared with the traditional way of lighting, white LED lamp the return on investment is the most important factor. After analysis, compared with incandescent lamps, LED lamps of the payback period of 1.7 years to 3.4 years; compared with halogen lamps, LED lamps of the payback period of 1.7 years to 3.5 years. Therefore, instead of incandescent and halogen lamps, the application of white LED has a very attractive rate of return on investment. Compared with the compact fluorescent lamp, in the application of the sector, LED lamp investment payback period of 4.5 years to 6.2 years; compared to straight tube fluorescent lamp and metal halide lamp, LED lamp does not have good payback period performance. Key technologies need to break through the white light LED in the field of indoor lighting to continue to expand the application of the share, but the white LED lighting is also facing many challenges. LED lights not only need to pay attention to the chip or packaging components of the relevant performance, but also need to focus on the study of LED lighting composed of a set of electronic technology, thermal management and optical technology, etc..
