A complete solar lawn solar wall light 97 led system includes: light source, controller, battery, solar cell module and light body. Solar wall light 97 led manufacturer is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, solar wall light 97 led will become the choice for energy-saving road lighting. Solar wall light 97 led is a high-efficiency solid-state light source based on a semiconductor PN junction that can emit light with weak electric energy. Under a certain forward bias voltage and injection current, it injects holes in the P area and injects into the N area. After the electrons diffuse to the active area, they recombine by radiation to emit photons, which directly convert electrical energy into light energy. In the daytime, solar cell modules convert light energy into electrical energy and store it in the battery through the controller.

Under a certain forward bias voltage and injection current, it injects holes in the P area and injects into the N area. After the electrons diffuse to the active area, they recombine by radiation to emit photons, which directly convert electrical energy into light energy. At night, the battery provides a light source through the controller, which converts it into light energy and lighting decoration. The solar wall light 97 led body mainly plays the role of system protection and day decoration, ensuring the normal operation of this cycle. Light source, controller and battery are the key to determining the performance of lawn solar wall light 97 led system. Must be optimized and reasonable configuration in the design.
The choice of light source
Since the solar wall light 97 led is limited by the module power, the power of the light source must be very small, from zero watts to several watts, and more 0.5W and 1W. At present, some solar lawn solar wall light 97 leds use energy-saving solar wall light 97 led as the light source. The light efficiency of ordinary energy-saving solar wall light 97 led is about 40×50L m/w, while the light efficiency of solar wall light 97 led has reached 90L/w, up to 120 Lm/w in the laboratory, under the same illuminance, solar wall light 97 led saves more than 40% of electricity than ordinary fluorescent solar wall light 97 led, and the conversion efficiency is higher. In addition, the service life of ordinary fluorescent solar wall light 97 led is 3000±5000 H. When the light attenuation reaches 70%, the theoretical life of solar wall light 97 led is about 100,000 h, and the actual service life can reach 50,000 h, which is normal The fluorescent solar wall light 97 led is more than 10 times longer. If you work 8 hours a day, a solar wall light 97 led can be used for 6250 days, so it does not need to be replaced frequently, which can greatly save maintenance costs. Solar wall light 97 led is called a green lighting source, and it does not contain toxic and hazardous substances (such as mercury). Avoid the secondary pollution of mercury caused by the rupture of the fluorescent solar wall light 97 led. At the same time, the solar wall light 97 led is driven by a constant DC current, which will not produce any stroboscopic phenomenon, will not interfere with radiation, and is harmless to the human body. The color index is above 80, the color of the object under the light is more real and the color is richer. Therefore, it is very suitable for solar wall light 97 led system. The important issues in the application are constant current and heat dissipation. Although it has been used in many solar lawn solar wall light 97 leds, these problems are not very good.
In high-power applications, heat dissipation is another major consideration. If the heat dissipation is not good, it will cause very serious light decay. Some serious six months may drop to half of the original. On the lawn solar wall light 97 led, most of the high power is a single application that can meet the traditional aluminum substrate. The impact is usually small, but it needs to be verified through experiments.
