The heat dissipation technology of LED street lights

As the birth of solar street lights, LED street lights can be said to be a lot of resources in our country, and they also provide great help to our environment, and truly realize the requirements of energy saving, environmental protection and green. With the rapid growth of the national economy, the contradiction between my country's energy supply and demand has become increasingly prominent. There is a serious shortage of power supply, and energy conservation is an urgent problem to be solved. Therefore, the development of a new type of high-efficiency, energy-saving, long-life, high color rendering index, and environmentally friendly LED street lamps is of great significance to the energy saving of urban lighting. The difference between LED street lamp manufacturers and conventional street lamps is that the LED light source adopts low-voltage DC power supply, and is a high-efficiency white light synthesized by GaN-based power blue LED and yellow. It has high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and display. The unique advantages of high color index can be widely used on roads. The outer cover can be made, the high temperature resistance can reach 135 degrees, and the low temperature resistance can reach -45 degrees. Household solar street lights have attracted much attention. The more people know them, the more they promote them. Solar street lights can meet the needs of rural areas, schools, development zones, and municipal roads. They don’t need lighting, and they’re scary! A full range of services from design, research and development of LED street lights to production. For non-lighting products, such as solar street lights, LED street lights, solar LED street lights, traffic lights, etc., for the installation of solar street lights, Fengqi talks scary! Comprehensive technical support, no quality problems, solar street lamps have many advantages different from traditional lamps. The heat dissipation technology of LED street lamp lamp holder is generally used for heat conduction plate, which is a 5mm thick copper plate. In fact, it is calculated according to the average temperature board, the heat source drops below the average temperature, they all increase the heat dissipation of the radiator, but the weight is very large. The weight of the street lamp head system is very important. The height of the street lamp head is generally 6 meters to 1 meter. If the risk increases, especially in the event of a typhoon, an earthquake may cause an accident. Some domestic manufacturers have adopted the world's first pin-type heat dissipation technology. The heat dissipation efficiency of the pin radiator is better than that of the traditional sheet radiator. Whether the buried temperature of the light-emitting diode is more than 15°C lower than that of the ordinary radiator, and the waterproof efficiency of the ordinary aluminum radiator is improved, and the weight and volume are increased. In the field of solar power generation, solar street lights have an important position. The solar street light system adopts the form of 'photovoltaic + storageThere is an urgent need for sunlight to illuminate solar energy, generate electricity from photovoltaic cells, charge the batteries, discharge them at night, and tell the street lights to frighten! Electricity is ok. A typical solar street light system includes batteries, batteries and street lights. The channel is characterized by safety, environmental protection, energy saving, and complex pipelines can be laid without manual execution. When you talk about it, everyone must have a question, what is the controller system? I want to talk about this topic today. In actual use, if the battery is properly controlled, the charging method will be shattered, and over-discharge will affect the battery length. D. In order to reduce the protection of the skin, the battery is correctly charged in the most effective way. Of course, it must be reasonably lifted. The so-called 'anti-explosion' phenomenon is that the battery charges the solar panel at night, and the voltage is prone to breakdown and damage the solar panel. The controller will effectively avoid this phenomenon and ensure that the battery provides normal power for the lamp. Reverse connection, as the name suggests, is the connection of lines, which can cause lamp failure or other damage. When the controller detects the reverse connection of the line, it will send a signal to the staff to correct the line in time. The overload is related to the protection of the controller itself. When the controller is too large and exceeds its rated value, the controller will automatically disconnect the circuit, wait for a period of time (the time set by the developer) to listen, reopen the circuit, or protect itself as a whole.
