Comparison of lighting principles of sodium lamps and LED street lamps

At present, my country is creating a resource-saving and environment-friendly society, and the concept of 'green lighting' is gradually gaining popularity. With the continuous advancement of science and technology and the rapid development of semiconductor material application technology, low-power LED light sources have been widely used in landscape lighting, and high-power LED solar street lights have attracted more and more attention from all aspects. 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, it 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, and the electrons and holes will recombine in the quantum well, and then will 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.
