Advantage of LED street lights

　　Ten City, ten thousand LED Street lights started in China. As for the huge business opportunities, LED street light manufacturers are highly focused. Normally, street lights use traditional high pressure sodium lights , low pressure sodium lamp overall efficiency glazing shortcomings caused a huge waste of energy , therefore , the development of new high efficiency , energy saving, long life, high CRI , green lights of the city has a very important energy-saving lighting meaning.

　　1, LED street light itself has a directional light , no light diffusing ensure light efficiency ;

　　2, LED lights have a unique optical design , the LED street light shines on the desired area lighting , that the road to further improve the efficiency of light to save energy ;

　　3 , The efficiency of the LED light source currently reached 100lm / W, but there is still much room for development, the theoretical value can reach 250lm / W. The luminous efficiency of the high-pressure sodium lamp is only increased with the increase in power , therefore , the overall light efficiency LED lights stronger than high pressure sodium ;

　　4, The CRI of LED street light is high pressure sodium high pressure sodium lamp, whose color rendering index of only 23 , while the LED lights color rendering index can reach 75 or more, from the visual psychological point of view , to achieve the same brightness, illumination LED lights mean you can more than 20% lower pressure sodium lamp ( lighting standards the United Kingdom ) ; further, at an intermediate level of vision , the human eye in the high color temperature environment things easier to distinguish than the low color temperature environment, to avoid the occurrence of certain dangerous state ;

　　5, The light loss of LED street light is small , less than 3% of the light fades per year , still reached a 10 -year road illumination requirements, therefore , LED lights in the use of power can be lower than the design of high-pressure sodium lamps ;

　　6, LED street lights automatically dimming can be achieved at different times to meet the lighting requirements , the maximum possible reduction in power and save energy ;

　　7, LED is low voltage DC devices, single LED driving voltage of safe voltage , so it is a more secure than using a high voltage power supply , especially for public places. DC characteristics of the LED is particularly suitable for solar and wind power are combined ;

　　8 , Only a small per unit volume of the LED die , it can be prepared into various shapes of devices and adapted to variable , earthquake prone environment ;

　　9 , Long life: theory of life can be used for more than 50,000 hours ;

　　10, LED switch can be frequently without worrying about the damage;

　　11 , Easy installation : LED street lamp directly replace the original sodium lamp installed on poles ;

　　12 , Excellent thermal control : LED junction temperature can drop 70 ° C or less , with the development of technology, the junction temperature still further down , the lower the junction temperature , in theory, the longer the life of the LED chip ;

　　13 , Reliable : the power circuit used in all high-quality components , each LED has a separate over-current protection and series-parallel , even if one is damaged , it will not cause other LED chip failure ;

　　14, LED light source does not contain toxic metals mercury , unlike high pressure sodium or metal halide lamps in damage to the environment when discarded .
