As the light source of solar street lamp, LED has many advantages compared with the traditional light source.
1, LED street light failure is small, a year of light failure is less than 3%, using 10 years still reach the way to use the illumination request, therefore, LED street light in the use of power design may be lower than the high pressure sodium lamp;
2, LED street light may be active dimming, can satisfy the lighting request at the moment, the possible landing power, save energy;
3, LED solar street light color higher than high pressure sodium lamp, high pressure sodium lamp color index is only 23, and LED street light color index can reach more than 75, from the perspective of visual psychology, to uniform brightness, LED street light uniformity may be more than high pressure sodium lamp down 20% (refer to the British way lighting standard); Moreover, at the side vision level, the human eye in the high color temperature environment than the low color temperature environment is easier to justify things, to avoid some dangerous conditions;
4, LED street light has light directivity, not only diffuse, ensure light efficiency;
5, heat dissipation control excellent: LED node temperature to below 70°C, with the growth of skills, node temperature is further falling, the lower the node temperature, in fact, LED chip life is longer;
6, LED can be on and off frequently without worrying about its damage;
7, LED is a low-voltage DC device, driving a single LED voltage for the insurance voltage, so it is a safer power supply than the use of high voltage power supply, especially for public occasions. The characteristic of DC makes LED specially suitable for connecting with solar energy and wind power;
8, reliable quality: circuit power supply all adopt high-quality components, each LED has zero over current shelter and series and parallel shelter, even if a damage, will not lead to the effect of the rest of the LED chip;
9. ED light sources do not contain harmful metal mercury, unlike high pressure sodium or metal halide lamps, which can be hazardous to the environment when scrapped. The wiring on the back of the solar panel is reverse buckle design, which can be gently pried open with a screwdriver. The wiring of the solar panel (red cap is connected to the positive pole line, black cap is connected to the negative pole line) corresponding to the positive and negative pole line separated from the black cap of the lithium integrated battery, and the wiring should be wrapped with electrical tape.
10. Device refinement: directly replace the original sodium lamp cap with the LED street lamp cap on the lamp pole;
11, long life: the actual life can use more than 50,000 hours;
12, LED street light has a weird secondary optical design, the LED street light to the required lighting area, namely the road, further improve the lighting efficiency, to achieve the goal of energy saving;
13, each unit LED grain only has a small volume, so it can be prepared into various shapes of devices, and suitable for variable, earthquake environment;
14, LED light source effect has reached 100lm/W, and there is a lot of space, the actual value can reach 250lm/W. Solar street lamp LED lamp head wire lithium control battery white cap separated, wiring attention to use electrical tape wrap. The luminous efficiency of high pressure sodium lamp is increased with the increase of power, therefore, the overall luminous efficiency of LED street lamp is stronger than high pressure sodium lamp;
