The heat dissipation technology of LED line lamp head generally adopts a thermal conductive plate, and the thermal conductive plate is a copper plate with a thickness of 5mm. In fact, it is a uniform temperature plate that heats the heat source evenly; there are also heat sinks to dissipate heat, but it is too heavy. In a street light headlight system, weight is very important. Generally speaking, the height of the lamp head of the street lamp is more than 6 meters. If it's too heavy, the risk increases, especially in the event of a typhoon or earthquake. Domestic manufacturers use the world's first needle-shaped cooling technology. The heat dissipation efficiency of the needle radiator is much better than that of the traditional chip radiator. Compared with the ordinary radiator, the connection temperature of the LED can be reduced by more than 15℃, and the waterproof performance is also better than that of the ordinary aluminum radiator. At the same time, the weight and volume of the radiator have also been improved.
In the field of solar power generation, solar street lights play an important role. The solar street light system adopts the form of "photovoltaic + energy storage" and is a typical independent solar power generation system. During the day, the sunlight is enough to generate electricity from the photovoltaic cells to charge the batteries, and at night to discharge the batteries to power the street lights. A typical solar street light system consists of a battery, a battery, a street light and a controller. Its distinctive features are safety, environmental protection, energy saving, no need to lay complicated pipelines, no need for automatic operation and execution. Having said that, you must have a question, what does a controller do? That's what I want to say today. In actual use, if there is no reasonable control of the battery, improper charging, overcharging and overcharging will affect the service life of the battery. In order to reduce the cost of protection, the battery should be charged in the most efficient way, and of course, the battery should be discharged in a reasonable way.
The so-called reverse charging phenomenon refers to the phenomenon that the battery charges the solar panel at night, so that the voltage is easily broken down and the solar panel is damaged. The controller can effectively avoid this phenomenon and ensure the normal power supply of the lamp battery. As the name suggests, a reverse connection is the reverse connection of the line, and it can cause the lights to turn off 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. Overload is related to the protection of the controller itself. When the controller load is too large and exceeds its rated load, the controller will automatically disconnect the circuit. After a period of time (set by the developer), the circuit will reopen, which protects not only the circuit itself, but the integrity of the entire system. The controller also has short circuit protection for lamps and solar panels. When a short circuit is encountered, the circuit is blocked. Lightning protection is to prevent lightning strikes from damaging the system.
