LED new technology LED as light source, should make full use of its advantages in the lighting equipment, improve its shortcomings. Embedded LED is used in lighting fixtures, due to the LED chip calorific value is big, the difficulties when make high-power lamps and lanterns. Companies are now working to solve one of the topics is 'hot'. The luminous efficiency is higher and higher, but the LED chip calorific value is still high. If do not take the cooling measures, the temperature of the LED chip will be too high, lead to the deterioration of chip itself and encapsulating resin performance, thus resulting in low luminous efficiency and shorten the life. LED the most important performance is 'long life', in order not to affect this metric, you need try to chip heat spread out. Improve the heat of the LED is the key to conquer high-power lighting lamps and lanterns. About LED lamps and lanterns of energy-saving situation, for different application types should know. Compared with the traditional light source, white light diode as monochromatic light diode have made outstanding contributions on energy saving. Initially LED is used as the indicator light instrument and then all kinds of light color of LED traffic light and display screen has been widely applied in large area, produced good economic and social benefits. 12 inches of red traffic lights, for example, it is with low light efficiency of 140 - watt incandescent lamp as light source, it produces 2000 lumens of white light. After the red filter, light loss 90%, only 200 lumens of red light. In the new design of traffic lights, the 18 red LED light source, including circuit loss, total power consumption of 14 watts, can produce the same light. Car light is also an important field of LED light source. In 1987, our country began to install high in the automobile brake lights, LED fast response (because Nanosecond) , you can make following vehicle drivers know driving conditions, as early as possible to reduce car crash happened. Energy saving of white light led lamps and lanterns is mainly used in small power, the original incandescent light source of lamps and lanterns, such as a flashlight, canister light, etc. LED street lamp has been in constant progress, steps walked faster and faster. Hope in the near future, the LED street lamp with excellent performance is more widespread in the context of the city. High power LED is used for road lighting starts in the highway tunnel lighting, using more than two years. Since June 2008 successfully installed the LED street light, LED street lamps, the actual use has more than one year. Now use the LED street lamp, manufacturer by accelerated aging test, and the testing and measuring the national inspection agency, 5000 hours of light failure rate is less than 3%, need 50000 hours thereafter droop to 70%. The data in more than a year of practice has proved, LED lights for road lighting has been very mature.
