(1) Compared with the service life, LED solar street light is a kind of semiconductor diode, and its light source theoretical life is very long (provided that it is within the specified junction temperature range and under the L70 light decay standard), but the overall life of a lamp is not The simple is the life of the light source, and the luminaire also includes the influence of the lens part. Therefore, the life of the final lamp should be limited to the shortest life part among all lamp parts. When the luminous flux attenuates to 30%, its life span reaches 50,000 hours, while the life of metal halide lamps is 6,000-12,000 hours, and the life of high-pressure sodium lamps is 20,000 hours. (2) Comparison of lighting effects of light ① Color rendering index LED white light: ① LED color temperature is 3500-7000K; ② Color rendering index is 80-93. Traditional high-pressure sodium lamps: ① the color temperature of high-pressure sodium lamps is 2000-2500K; ② the color rendering index is 20-30. From the above comparison results, it can be seen that the high-pressure sodium lamp has a low color rendering index, poor color rendering, and poor reductibility of the color of the object itself, which is not conducive to judging the depth of the surrounding environment; the LED light source has a high color rendering index, good color rendering, and good performance. to restore the actual color of the object, but the white light is cooler. Look at high pressure sodium lamps, which are closer to natural light. At this stage, the light efficiency of LED solar street light lamps is slightly better than that of sodium lamps. With the development and maturity of LED technology, the light efficiency of lamps and lanterns will be greatly improved. ②Dimming function: LED solar street light has a perfect dimming function. The light output of LED solar street light is proportional to the working current, so it can be dimmed by reducing the current. In addition, because the frequent switching of LED solar street light does not cause much damage to it, the LED solar street light can also be adjusted by pulse width adjustment. By adjusting the duty cycle and operating frequency of the voltage, the LED solar street light can be effectively adjusted The luminous intensity of the street light. (3) Light utilization rate and luminous rate LED solar street light has the smallest loss of luminous flux. Unlike traditional light sources, LED solar street light is a light source that emits light in half space. The high-pressure sodium lamp is a light source that emits light in all spaces. It needs to change the direction of the outgoing light in one half of the space and project it to the reflector in the other half of the space. At the same time, it is inevitable to absorb the light and block the light source itself. And using LED solar street light as the light source, there is no loss in this respect, and the utilization ratio of light is also higher than that of high-voltage nano-lamps. At present, LED solar street light is 65-100 lumens/watt, while high pressure sodium lamps can reach 140 lumens/watt. The spectrum of high-pressure sodium lamps is concentrated in yellow, and the color temperature is 2000-2500K, and the fog penetration is strong. A very big problem with sodium lamps is that the lighting continuity of sodium lamps is very poor. In the working state of the sodium lamp, the temperature in the lamp cavity should exceed 150 degrees, and the temperature of the LED solar street light is 30% of that of the high-pressure sodium lamp. The light-emitting effect and lifespan. The LED is relatively stable. (4) Comparison of energy saving and environmental protection LED solar street light is highly energy-efficient and has ultra-low power consumption. The energy consumption of white LEDs is only 1/10 of incandescent lamps and 1/4 of energy-saving lamps. And the light source of LED solar street light does not contain harmful metal mercury. The high-pressure sodium light source contains metallic mercury and metallic sodium (which turns into mercury vapor and sodium vapor after being energized), and has a short lifespan (compared to LEDs), and subsequent disposal of waste products will pollute the environment. LED solar street light has good shock resistance and convenient transportation. Solid state package, belonging to cold light source type. So it is easy to transport and install. (5) Comparison of structure and cost LED lamps generally have obvious graininess, and their light-emitting positions are relatively concentrated. Therefore, LED needs to do a better design on the uniform light, expand the point light source into a surface light source as much as possible, and improve the comfort of the eyes. Then there are many products will do LED dimming design to save energy. At present, the LED solar street light designed and produced by most manufacturers is extremely heavy, often exceeding 10 kilograms. Such a large self-weight tends to overload the light pole and reduce its wind resistance. Most manufacturers of LED
solar street lights design LED solar street lights to be replaceable, that is, to directly replace the existing lamps. And increase the current of the LED to reduce the number of wicks to save costs while maintaining the same brightness, or to reduce the PCB area, or to reduce safety components.
