Description

A New Solar LED Street Light

technical field

The utility model relates to the field of solar lighting, in particular to a novel solar LED street lamp.

Background technique

With the development of the economy and the progress of society, human beings have higher and higher demands on energy, and finding and developing new energy sources has become an urgent issue facing human beings. Today's dominant power generation methods such as thermal power, hydropower, and nuclear power all have the risk of depletion of raw materials or damage to the environment. However, the sunlight irradiated on the earth contains huge energy. According to strict calculations by scientists, the solar energy irradiated on the earth for about 40 minutes is enough to meet the energy consumption of human beings around the world for one year. Moreover, solar energy is clean and pollution-free, inexhaustible, so solar power generation is known as the most ideal energy source. As an efficient new light source, LED street lamps have well-known advantages. The solar LED lighting system combined with solar power generation technology and LED lighting technology is more and more popular among people. Solar LED street lights use sunlight as energy, charge during the day and use at night, without complicated pipeline laying, the layout of lamps can be adjusted arbitrarily, easy to install, low cost, safe, energy-saving and pollution-free, no manual control, stable and reliable work. Therefore, solar LED lighting street lamps have gained unprecedented popularity.

At present, there are many styles of solar LED street lights on the market, but the structure is basically the same, mainly including solar panels (photoelectric panels), batteries, controllers, light poles and lamps. However, for the existing solar street lamps, most of the solar panels adopt a rectangular flat structure and are fixed on the top of the street light pole, facing the relatively strong direction of direct sunlight at a certain angle of inclination. However, since the sun's trajectory is constantly changing, the front of the solar panel is not always perpendicular to the sunlight, resulting in unstable output current of the solar panel, which has a great impact on the charging equipment and the battery, greatly reducing the service life of the equipment. Although there are currently rotatable solar panels that automatically track the sun's rotation to obtain the best light intensity on the market, their high cost input and strict requirements for installation space and site have greatly restricted their popularization, and automatic tracking The power system itself also needs to consume electric energy, so the input-output ratio is not ideal. In addition, during the installation process of flat-panel solar panels, especially in areas with strong winds, there are strict requirements on wind resistance.

Therefore, the market calls for the emergence of a solar street light with uniform effective illumination area, stable power output, simple and convenient installation, firm and reliable, and low equipment cost.

Further, the spherical solar cell panel is a hollow structure, and the surface of the hollow structure is covered with alternating warp and weft grids for installing corresponding monocrystalline silicon wafers.

Furthermore, the light pole is cylindrical and made of stainless steel and aluminum alloy, which makes the installation of the spherical solar panel on the LED street light pole convenient and firm, and has good wind resistance.

Further, the solar controller has a control interface through which the control program of the controller can be downloaded and controlled in real time.
