The rapid development of cities, LED lighting industry matures, LED street lamp is more welcomed by the lighting market. In major cities of the highway, park, plaza and other places are set on the LED street light, the wide range of application is to let people surprise. For this, we asked, why can get popular LED lights? Actually LED street lamp can gain the favour of market benefited from it is to use LED light source. The LED light source has the very big difference with the traditional incandescent lamp, fluorescent lamp. LED is belong to the cold light source, we effectively control the LED junction temperature, prevent it from under the condition of the continuous high temperature lead to the LED chip, phosphor, encapsulating resin reduced life spans, LED street light the advantages of high efficiency and long life of the obvious. LED street lamp power supply high efficiency directly affects the efficiency of the whole lighting lamps and lanterns, the LED is electron and hole recombination luminescence, beam depends on the current, the LED constant current drive is the assurance of quality. Avoid the LED current is too large, the heat generated by the also increase, lead to low luminous efficiency. LED street light is not like ordinary mains street lamp, ordinary mains street lamps light source area is small, high altitude, the human eye look easy dizziness; But the LED street lamp in LED itself to have the light emitting area is small, light within the scope of radiation in the hemisphere, with advantages of light distribution rotational symmetry, plus lenses and mirrors, can make a good light source. Focus on a specific wavelength of LED street lamp light spectrum a very narrow range, no radiation of infrared light. LED street lamp life for an average of 80000 hours, according to 10 hours a day, life for eight years. With safety, energy saving, environmental protection, long service life, fast response speed, and low maintenance cost, don't want to get the favour of market all difficult! http://www。 jhzm88. com
