* HLD939 the LED street lights * Scope of application: 
 HLD939 LED street lamps * used in the factory road, at all levels of roads, urban main road and other places for road lighting. 

 Histon LED street lamp characteristics and advantages: 

 Long life: 50,000 hours or more, a three-year quality assurance. Inadequacies in the life of the power supply is not guaranteed. 

 2, High luminous efficiency: ≥ 100LM chip, compared to traditional high pressure sodium lamps to energy-saving more than 75%. 

 3, easy to install: no need to Jiamai cable without the need rectifiers, etc., directly to the street lamp installed on the poles connected to the light source nested original lamp shell. 

 4, thermal control, excellent: summer temperature was controlled at 45 degrees, and passive cooling, lack of summer heat protection. 

 Reliable quality: the circuit power supply used in all high-quality components, each LED has a separate over-current protection, without worrying about damage. 

 6, the light color uniform: without the lens, do not sacrifice in order to improve the brightness and uniform light color, thus ensuring the aperture light color uniform. 

 7, the LED does not contain toxic metals mercury, unlike the high pressure sodium or metal halide lamp on the environment at end of life hazard. 

 The principle of high-power LED street lamp energy saving effect is remarkable, instead of the high-pressure sodium lamp can save 60% or more. (To be known) 

 Low maintenance costs: very low maintenance costs compared to traditional lights, LED lights, after less than six years to recover all input costs.
