LED street light heat dissipation technology; LED street lamp cooling technology, the use of more general way for thermal conductive plate, is a 5 mm thick copper plate, is actually mean temperature plate, the heat source temperature drop; Also with a heat sink for cooling, but too much weight. Weight on the street lamp system is very important, because of the high street light is 9 meters, if too much risk increases, especially in typhoon, earthquake can cause accidents. Domestic manufacturers adopt the world's first needle cooling technology, acicular radiator cooling efficiency than conventional flake radiator has a great range, can make the LED junction temperature is lower than ordinary radiator more than 15 ℃, and the waterproof performance is better than ordinary aluminum radiator, also improved on the weight and volume. In addition, in view of the high power LED lamps and lanterns of the development of graphite heat sink also has a good thermal conductivity and thermal performance. Led street light points of choose and buy; Luminous efficiency of LED lighting technology becoming mature, high power LED light source has can meet the general street lamp luminous flux as needed. The average high pressure sodium lamp light efficiency is 100 lm/W, commonly used in high power LED is 50 - 60 lm/W, with good foreign * LED chip can reach 80 lm/W, the higher luminous efficiency, energy saving effect means that the better, it is also a choice LED street lamp * one of the important indicators. Leds, however, does not have explicitly stipulated in the standard, so must be carefully confirmed when purchasing solar led street light. LED street lamp light failure and some businesses, in order to reduce costs, with hundreds of 0. The small power LED 5 w. However, this kind of small power LED light failure is very serious, its light failure and 80% of life is only 1000 hours. As the need for long-term use, so the street lamp is good can not be allowed the use of this kind of small power LED, selects the high power LED Generally refers to more than 30 w) , the light failure will be much better. LED street light weight problem of LED street light due to the complexity of high technical content, composition and so on reasons, some high power lamp holder will weigh far more than ordinary high pressure sodium lamp, so the support for the corresponding material requirements are higher. However, some LED lights manufacturer has as much as possible to reduce the weight of the LED lamp holder, from the original single lamp holder about 30 kilograms, dropped more than 10 kilograms, weight loss and the trend of decline further. LED street light heat dissipation LED because is semiconductor components, the chip is affected by temperature and reduced to 30% of the initial luminous flux, will lose the meaning of lighting, or put an end to the life, the life of the high power LED street light in theory - 3 50000 hours, but the premise is have good heat resistance. It is worth mentioning that the domestic existing factory adopted the global superior acicular heat dissipation technology. In addition to the above products, the company also supplies a scenery complementary street lamps, yangzhou high lamp and other products, our company has the practical technology, with '*' * * operations team, to create on the premise that the user experience for your service, the service of the supreme good to beauty is our endless pursuit. Because of the people-based, so trustworthy; And * * professional, trustworthy. The above information is for reference only. For details, please contact related staff to answer you.
