The birth of the solar street lights can say to save a lot of resources in our country, which brings great help to our environment, truly achieve the demand of energy saving, environmental protection, green. Manufacturer of LED lights ED street lamp light is higher than high pressure sodium lamp many color, high pressure sodium lamp only around 23, color rendering index and the LED street light color rendering index above 75, think in terms of visual psychology, to achieve the same brightness, LED street light can, on average, more than 20% lower than the high-pressure sodium lamp. LED street lamp manufacturers of LED street lamp with conventional street lamps, the LED light source adopts low voltage dc power supply, by GaN power type synthetic efficiency white light, blue light leds and yellow is efficient, safe, energy-saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, can be widely used in road. Housing available, resistance to high temperature of 135 degrees, low temperature resistant da 45 degrees. Nowadays, solar street light has attracted widespread attention, approved by the people more and more, its sales is amazing. Solar street lamps can satisfy rural, schools, some development zone and city road lighting requirements, to provide overall apparel production design, research and development. Used for lighting products, including solar street light, solar LED street lights, traffic lights, etc. For installation and operation of solar street lamps provide comprehensive technical support, without any quality problem. At the same time, solar street light there are many significant advantages compared with traditional street lamps. LED street light heat dissipation technology commonly used as a heat conducting plate. It is a 5 mm thick copper plate. It is actually a temperature balance sheet, heat it heat source. It also has heat sink cooling, but the weight is too big. Weight in the street lamp head system is very important. In general, street lamp head to 6 m tall. If too heavy, the risk will increase. Especially in the case of typhoon and earthquake, the accident may occur. Some domestic manufacturers adopt the first needle cooling technology in the world. Needle radiator cooling efficiency is much higher than traditional chip radiator, can make the LED junction temperature is lower than ordinary radiator more than 15 ° C, the waterproof performance is better than ordinary aluminum radiator, and the weight and volume of them also improved. Solar street light plays an important role in the field of solar power. Solar street lamps system takes the form of 'photovoltaic + energy storage', is a typical independent solar power system. During the day the sun is enough to power generation from shaoguan photovoltaic cells, to recharge the battery, battery discharge at night, and provide energy for street lights. A typical solar street light system is composed of battery, battery, street lamp and the controller. Its salient features are safe, environmental protection, energy saving, without laying complex pipe, no need for manual operation and automatic execution. When it comes to this, you must have a problem, controllers is stem what of? This is I today to discuss the topic. In actual use, if the battery is not reasonable control, the improper charging, overcharge and over discharge will affect the battery life. In order to reduce the cost of protection, reasonable charging is the most effective way to battery, of course also want reasonable discharge. The so-called reverse charging phenomenon is battery charging at night the phenomenon of solar panels, making voltage can easily break through the damaged solar panels. Controller will effectively avoid the phenomenon, to ensure normal power lights and lamps and lanterns of the battery. Reverse connection, just as its name implies, the line connecting the reverse, form bright lights or other damage, the controller will detect the signal circuit reverse connection, staff in a timely manner to correct lines. Overload, its relative to the protection of the controller itself. When the controller when the load is too large and more than the rated load, the controller automatically disconnect circuit and over a period of time ( Set the time by the developer) After reopen the circuit, which not only protect themselves, and to protect the integrity of the whole system.
