Promoting solar LED street lights according to local conditions

With the rapid development of new solar energy, solar street lights and solar LED street lights have also been promoted and applied in many cities and villages, but at the same time, some shortcomings and deficiencies have also been exposed, especially on the main roads of the city. The application of the illuminance and the reliability under continuous rainy and rainy conditions and the usual maintenance are all useless. The main reason for this is that the replacement power of the solar cell only needs about 17%, and the power required by the road lighting solar cell is higher. At the same time, the quality and lifespan of the related supporting equipment cannot meet the relevant needs, which are all unsatisfactory reasons. The existing difficulties that have not been dealt with temporarily have not been dealt with. Before the treatment, the installation of solar LED street lights should be carried out moderately and appropriately . 1. The development of solar LED street lights according to local conditions is the first, the lack of sunshine or the lack of equipment is not suitable for the area, and the cities where high-rise buildings are built and the journey is infinite should have as little equipment or no equipment as possible; The illumination of the primary and secondary roads and the welcome road is required. It is recommended that if the city is equipped with equipment, the suitable equipment should be located in the house, park, green space or phenomenon. These local rainy nights are sparsely populated or even unmanned. Dark spots or no lights have no big effect. If the equipment is installed on the road in the city, it is recommended to use the method of complementary lighting with the mains. This method only needs to consider the power needs of the longest sunshine time in a year and the shortest lighting time at night. Others can be The utility power is compensated, the efficiency of the solar cell is maximized, the capacity of the battery can be minimized, the system cost is the least, and the solar energy system has the reliability to reach the highest level, which is especially beneficial for the use of solar LEDs on the route where the lighting cable is originally laid in the city. The retrofitting of street lamps is more beneficial for cities that use dual-circuit power supply for street lamps. Of course, the use of solar energy and utility power complementation should be done in related work, such as the need to consider the lighting requirements of different distances, the selection of the point where the utility power is cut in, etc. Third, solar LED street lamps can be properly installed in areas with scarce power sources such as urban external effect areas, villages, islands, scenic spots, mountain tops, etc. or in emergency lighting for disaster relief, which can solve the doubt of whether there is lighting. 2. Properly promote solar LED street lights. Both solar energy and LED are new technologies, new power, and new light sources. They are destined to occupy an important position in the future, but they are still in the development period. Inconsistency, large color temperature error, low level of secondary light distribution treatment, incomplete description of driving power supply, its life is much lower than that of LED itself, low solar cell replacement power, short battery life, difficult synchronization control, etc. Many questions remain to be dealt with. We should view the development and development of solar LED lighting objectively and rationally, be optimistic about its future prospects, support and promote its development with a lively and enthusiastic attitude, and improve and advance in application. But it still has its own benefits, such as the application of solar LED lighting in some specific occasions (islands, scenic spots, mountain tops, remote locations, etc.), in phenomenal lighting (house lights, lawn lights, etc.) and solar energy that can be promoted in the future The advantages are still significant in the application of power supply in the system area network, and the demonstration application also has a lively meaning. But it should not be promoted blindly and disorderly. Development requires a process. If LED lighting cannot be treated correctly, there will be too much investment and waste of investment when talking about large-scale applications today, leaving too many dangerous questions for the future.
