New high efficiency light source, especially white light source (applicable to general lighting) to reduce the development of lighting power consumption has very important role, because it can reduce power consumption growth speed, and reduce the cost of the new power network capacity, reduce energy consumption and reduce emissions into the atmosphere of the greenhouse gases and other pollutants. LED light bulbs, especially white LED light, because of its and the traditional light source are the theory and compared the superiority of the real, well received by the professional people of all ages. It has also to develop the world for lighting a new technology, and the illumination energy conservation design provides more choice. The author on the performance of the current situation, LED a brief introduction and analysis.
LED the advantages of the As mentioned above, as a kind of cold light, LED with many traditional light sources can match advantage:
(1) don't need air, do not use glass shell, impact resistance, vibrate resistance, not easy and broken, easy to transport.
(2) The light source unit Lesser, make more flexible cloth lamp, and be able to better achieve lighting at night "see light see light source" the effect.
(3) can well control of light spectrum, which can be used for the museum and galleries local or focus lighting.
(4) compared with traditional light source in the higher the luminous efficiency, theoretically led the luminous efficiency of more than 200 lm/w, thus has the potential of energy saving is huge.
(5) to live longer, laboratory lifetime 100000 h, switch times are over 100000 times, and start at a very fast rate.
(6) can through the control of semiconductor glow of semiconductor materials with the size of the picture ban, which sends all the light color, and chroma higher.
(7) light source added in the Mercury, be helpful for protecting the environment, can be recycled.
(8) LED has the very strong directional, which can better control the light, and improve the system of lighting efficiency.
(9) use the low voltage dc, has the load of small, weak, and the advantages of security interference.
(10) without the light of the ultraviolet ray, be helpful for human body health, and do not attract mosquitoes.
