With the rapid development of the national economy, the demand for energy is increasing day by day, and energy prices are also rising. Electricity is an important part of my country's energy, of which lighting electricity accounts for a large proportion. In the context of my country's accelerating urbanization process, the number of lamps for urban road lighting is increasing at a rate of 1.5-2 million per year. With the acceleration of urbanization in my country, the proportion of road lighting electricity consumption will gradually increase. The following will explain the characteristics and energy-saving potential of high-pressure sodium lamps and LED solar street light in road lighting; the light-emitting principle of LED solar street light: LED (Light Emitting Diode), light-emitting diode, is made of Ⅲ-Ⅳ group compounds , is a solid-state semiconductor device that can directly convert electricity into light. The heart of LED is a semiconductor wafer, the semiconductor wafer consists of three parts, one part is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor. When the current acts on the wafer through the wire, the electrons and holes will be pushed into the quantum well, where the electrons and holes recombine, and then emit energy in the form of photons, which is the principle of LED light emission. The wavelength of light, which is also the color of light, is determined by the material that forms the P-N junction. The light-emitting principle of high-pressure sodium lamps: high-pressure sodium lamps use electric arcs between the electrodes at both ends of the arc tube after being energized. Due to the high temperature of the arc, the sodium amalgam in the tube is heated and evaporated into mercury vapor and sodium vapor. During the movement, the atoms of the discharge material are struck to obtain energy to generate ionization or excitation, and then return from the excited state to the ground state; or from the ionized state to the excited state, and then return to the ground state in an infinite cycle. At this time, the excess energy is Released in the form of optical radiation, light is produced. High-power LED solar street light is a new type of lighting method that realizes lighting needs by lighting light-emitting diode groups with DC low voltage. It has the characteristics of high brightness and good color rendering. In addition, because the input of LED solar street light is low voltage Direct current can be combined with solar energy, making solar LED solar street light a possibility for future road lighting. To sum up, compared with the use of high-pressure sodium for street lighting, the use of LED solar street light is more energy-saving and environmentally friendly. There is no doubt that with the advancement of science and technology, energy-saving and high-efficiency light sources will continue to emerge. As a road lighting designer, we should continue to innovate and design, master the application of new lighting technologies and new equipment at any time, and always put energy conservation and environmental protection at the top of our work. solar street light,solar street light manufacturer,high pole light,high pole light manufacturer,street light,street light manufacturer,street light,street light manufacturer,
