The performance of LED light source and high pressure sodium lamp are comparable

Master 　　 knows that the high-pressure sodium lamps and low-pressure sodium lamps that are widely used in the public power street lamp industry in my country, the reason why they choose to use sodium lamps is because they have the characteristics of high light efficiency and long life. Take a high-pressure sodium lamp as an example: the light efficiency is 120lm/w, and the average life span can reach 24,000 hours. But it also has its own significant defects, that is, the color temperature (Ku003d1900/2200/2500) is too low, and the color rendering index (Rau003d23/60/90) is too poor. In order to solve the problem of low color temperature and serious reddish color of high-pressure sodium lamps, the widely used method is to increase the power so that the power can reach 250-400W and use a super luminous flux value to compensate for the color cast of the object. The average illuminance value required by the national standard JT/T367-1997 'Technical Conditions for Highway Lighting' is mostly 15LX in the environment, and does not require high luminous flux. That is to say, in many environments, it is not necessary to use sodium lamps with such high power and high luminous flux to illuminate, but because of the low luminous flux environment, all objects are severely discolored in the city under the lamp, and are widely yellowish.



　　 LED as a new type of light source, its luminous efficiency currently reaches 130Lm/pcs (theoretical value can reach 200lm), and its life span is more than 100,000 hours. It can be used for almost 30 years because of the limitations of the lamp housing and wiring. , So generally speaking, the life span of LED lamps is ten years. Although its light efficiency is lower than that of sodium lamps, its color temperature is much higher than sodium lamps. The color temperature of ultra-bright white LED can reach 15000K, and the color rendering index is even closer to 100. That is to say, the use of LED light sources can greatly reduce the power of the luminaire and at the same time greatly reduce the power consumption, so the country will vigorously advocate the widespread use of LED products. In order to adapt to the rapid growth of the market's demand for LEDs, my country has made LED as one of the '31 electronic products encouraged by the country to encourage growth' and one of the '20 electronic products and technologies that encourage foreign investmentAt present, in the domestic market, LED products are mainly used as indicator light sources, like traffic lights. With the joint efforts of domestic and international scientific research institutions and numerous manufacturers, LED as a lighting source has increasingly shown its weird advantages, but the overall market is still in the Ru0026D and experimental stage, and there are no high-power products at home or abroad. Jiangsu Naite Lighting Electric Co., Ltd. is a manufacturer engaged in the production and design of solar street lamps and high-pole lamps. With 20 years of experience in the production of solar street lamps, it has created the most professional solar street lamp manufacturer. Contact number: 13805257308. , The marketed products are widely below 20W.



　　 The new white LED street lamp series currently launched by our company mainly include 6W, 9W, 18W, 30W, 60W, 100W, 150W, etc. Among them, 150W LED lamps can completely replace the 400W sodium lamps used in backbone roads, and the light color Bright, brilliance and pure, without deviation
