The country strongly encourages energy-saving and environmentally friendly products, and LED lights are undoubtedly the biggest beneficiaries. With the promotion of the country, LED lights seem to be able to occupy the entire market and become the dominant force in this market. One mountain cannot accommodate two tigers, and the position of energy-saving lights is greatly inferior to before. Although LED street light manufacturers have made such a big move and drive, it seems that consumers are not very interested. Although national policies promote the development of LED lights, the development of LED lights itself is still in its early stages, with significant price fluctuations and gaps. Customers cannot measure the quality of products, and various quality LED lights are mixed up, confusing their eyesight, and leading to a decrease in consumer confidence. Therefore, LED lights have not kept up with the pace.

LED is a light source that emits light into half space, while traditional light sources such as high-pressure sodium lamps and metal halide lamps emit light into the entire space. Compared with the envelope angle of the reflector on the surface of the light emitted, a large part of the light emitted by traditional light sources needs to be reflected or refracted by the optical system before it can be emitted. The efficiency of the optical system's utilization of light determines the overall efficiency of the lamp, and traditional light sources have a larger volume, which reduces the efficiency of the lamp due to absorbing and reflecting secondary light. LED has the characteristic of emitting light into the board space, greatly reducing the proportion of light absorption by the light source, which is one of the advantages of LED lamps in terms of lamp efficiency.

The heat island effect of solar panels can reduce the working efficiency and service life of solar panels. In order to maintain the working efficiency and service life of solar panels, we need to prevent the heat island effect of solar panels. Understanding the heat island effect of solar panels has both external and internal reasons, and generally external reasons are the main reasons for the heat island effect of solar panels, The heat island effect generated internally has been considered and resolved during the production of solar panels.

If the solar cell module is obstructed by other objects, such as bird droppings, tree shade, etc., for a long time on the surface of the solar cell panel, the obstructed solar cell module will seriously heat up at this time, resulting in a heat island effect. This effect will cause serious damage to solar cells. Some or all of the energy generated by illuminated solar cells may be consumed by obscured solar cells. In order to prevent solar cells from being damaged due to the heat island effect, a bypass diode needs to be connected in parallel between the positive and negative poles of the solar cell module to avoid the energy generated by the illuminated solar cell module being consumed by the shielded solar cell module. Its function is to provide a current path when the module is open or shaded, so as not to cause the entire series of solar cell modules to fail.
