The important reason of LED Street Lighting popularization:
1. The characteristic of LED Street Lighting--one-way of light, no diffuse of light, guarantee illumination efficiency;
2, LED Street Lightings have a unique two optical design, will be led street light to the required lighting area, further improve the lighting efficiency, in order to achieve energy-saving purposes;
3, LED light source efficiency has reached 100lm/w, and there is a great development space, theoretical value of 250lm/w. The luminous efficiency of high pressure sodium lamps increases with the increase of power, therefore, the overall light efficiency LED Street Lighting is stronger than the high-pressure sodium lamp;
4, the light color of LED Street Lighting is much higher than the high pressure sodium lamp, high-pressure sodium lamp color index is only about 23, and led street color index to more than 75, from the visual psychological point of view, to achieve the same brightness, led street light illumination average can be lower than the high-pressure sodium lamp to reduce more than 20%, (referring to the British principle of lighting standards);
5, LED street light fade small, one years of light decay less than 3%, the use of 10 years still reach the road use illuminance requirements, and high pressure sodium light, one years has dropped more than 30%, therefore, LED Street Lighting in the use of power design can be lower than the high-pressure sodium lamp;
6, LED Street Lighting has the automatic control energy-saving device, can realize in the different time period illumination request condition under the maximum possible reduction power, saves the electricity;
7, LED is a low-voltage device, driving a single led voltage for the safety voltage, the series of single LED power is 1 watts, so it is a more secure than the use of high-voltage power supply, particularly applicable to public places (such as: street lighting, mine lighting, automotive lighting, civil lighting, etc.);
8, each unit led small pieces only very small volume, LED Street Lighting so can be prepared into a variety of shapes of the device, and suitable for the changeable environment.
9, Long life: can use more than 50,000 hours, provide three years of quality assurance.
10, light efficiency: the use of ≥100lm above the chip, compared to the traditional high-pressure sodium lamp can save more than 75%.
11, easy to install: No need to add the cable without rectifier, etc., direct lamp lamp installed on the lamp rod connected or the light source embedded in the original light shell.
12, excellent thermal control: Summer temperature control at about 45 degrees, LED Street Lighting and the use of passive heat dissipation method.
13, the quality is reliable: the circuit power supply all uses the high quality component, each led has the separate overcurrent protection, does not need to worry about the damage.
14, light color uniformity: no lens, LED Street Lighting not to improve the brightness and sacrifice uniform light color, so as to ensure that no aperture light color uniformity.
