The heat dissipation technology of LED street lamp heads usually adopts a heat-conducting plate.
The birth of solar street lights can be said to have saved a lot of resources for our country, brought great help to our country's environment, and truly realized the requirements of energy saving, environmental protection and green. LED street lamp manufacturers ED street lamps have much higher light color rendering than high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only about 23, while the color rendering index of LED street lamps is more than 75. From the perspective of visual psychology, it can reach the same brightness and the illuminance of LED street lamps is average. It can be reduced by more than 20% compared with high-pressure sodium lamps. 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. Unique advantages such as 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. Nowadays, solar street lights have attracted widespread attention, and are more and more recognized by people, and their sales are also amazing. Solar street lights can meet certain requirements of rural areas, schools, development zones and municipal road lighting, and provide design, research and development for the production of overall clothing. Used in lighting products, including solar street lights, solar LED street lights, traffic lights, etc. It provides comprehensive technical support for the installation and operation of solar street lights without any quality problems. At the same time, solar street lights have many significant advantages compared with traditional street lights.
LED street lamp heat dissipation technology is generally used as a heat conduction plate. It is a 5 mm thick copper plate. It is actually a temperature equalization plate, which heats the heat source. It also has heat sinks to dissipate heat, but it is too heavy. Weight is very important in street lamp head systems. Generally speaking, the lamp head is six meters high. If it is too heavy, the danger will increase. Especially in the case of typhoons and earthquakes, accidents may occur. Some domestic manufacturers adopt the world's first needle-shaped heat dissipation technology. The heat dissipation efficiency of needle-shaped heat sinks is much higher than that of traditional chip heat sinks, which can make the junction temperature of LEDs more than 15°C lower than ordinary heat sinks, have better waterproof performance than ordinary aluminum heat sinks, and their weight and volume have also been improved.
Solar street lights play an important role in the field of solar power generation. The solar street light system adopts the form of "photovoltaic + energy storage", which is a typical independent solar power generation system. Sunlight during the day is enough to generate electricity from the photovoltaic cells in Shaoguan to charge the batteries, and discharge the batteries at night to provide electricity for street lights. A typical solar street light system consists of batteries, batteries, street lights and controllers. Its salient features are safety, environmental protection, energy saving, no need to lay complicated pipelines, no manual operation and automatic execution. Speaking of this, you must have a question, what does the controller do? This is also the topic I will discuss today. In actual use, if there is no reasonable control of the battery, improper charging method, overcharge and overdischarge will affect the life of the battery. In order to reduce the cost of protection, reasonable charging is the most effective way of batteries, and of course they must be discharged reasonably.
The so-called reverse charging phenomenon is a phenomenon in which the battery charges the solar panel at night, so that the voltage can easily break through the damaged solar panel. The controller will effectively avoid this phenomenon and ensure that the lights and lamps are normally powered by batteries. Reverse connection, as the name suggests, the line connection is reversed, resulting in the light is not bright or other damage, the controller will send a signal when the line reverse connection is detected, and the staff will correct the line in time. When overloaded, it is relative to the protection of the controller itself. When the load of the controller is too large and exceeds its rated load, the controller automatically disconnects the circuit and reopens the circuit after a period of time (the time set by the developer), which not only protects itself, but also protects the integrity of the entire system .
