The sustainable development of energy-saving is no longer a selective question, but in today's world of the future development of the road will do. New light source represented by LED to replace the traditional light source, is sparking a infinite innovation lighting occupation. Driving the new lighting products are continuously under the complete innovation skills upgrading, from incandescent bulbs to energy saving lamp, halogen lamp to LED lights, lighting products completed energy-saving upgrade together, also got very good improvement in comfort, lighting effects are also more diversified. As a representative of the green LED lighting energy-saving light source, become the most market potential of popular occupation, relative to the light source more sophisticated skills, LED finally has which lead? 1 energy saving. 2 safety and environmental protection. 3 the use of long life. 4 fast response. 5 high luminous efficiency. The 6.LED element has the advantages of small volume. 7.LED ray energy of high concentration. 8.LED light emitting strong directivity. 9.LED low voltage DC power can be driven. 10 but better control luminescence spectra composition. 11 controllable semiconductor light emitting layer and a semiconductor material stop web size. 12 high color.
