Solar street lights are a new type of energy-saving product. Using sunlight to collect energy can effectively relieve the pressure on power stations, thereby reducing air pollution. In terms of configuration, LED light sources, solar street lights are well-deserved ace green environmentally friendly products.
The energy-saving efficiency of solar street lights is well known to us, but not many people know how to maximize the energy-saving effect of solar street lights through the setting of some details. In previous articles, the working principle of solar street lights has been introduced in detail, and some parts will be briefly repeated here.
Solar street lights are composed of four parts: solar panels, LED lamps, controllers, and batteries. The controller is the core coordination part, which is equivalent to the CPU of a computer. By setting it reasonably, it can save battery energy to the greatest extent and make the lighting time more durable.
The controller of solar street light has multiple functions, the most important of which are time period setting and power setting. The controller is generally light-controlled, which means that the time of lighting at night does not need to be set manually, but it will automatically turn on after dark. Although we cannot control the on time, we can control the light source power and off time. We can analyze the lighting needs. For example, the traffic volume is the highest from dark to 21:00. During this period, we can adjust the power of LED light source to the maximum to meet the brightness requirements. For example, for 40wLED lamp, we can adjust the current to 1200mA. After 21:00, there will not be many people on the street. At this time, too high lighting brightness is not needed. Then we can adjust the power down. We can adjust it to half power, that is, 600mA, which will save half of the power compared to full power for the whole period. Don’t underestimate the amount of electricity saved every day. If there are multiple consecutive rainy days, the electricity accumulated on weekdays will play a big role.
Secondly, if the capacity of the battery is too large, it will not only be costly, but also consume too much energy when charging; if the capacity is too small, it will not meet the power demand of the street lamp, and may also cause the street lamp to be damaged in advance. Therefore, we need to accurately calculate the required battery capacity based on factors such as the power of the street lamp, the local sunshine duration and the night lighting duration. After the battery capacity is reasonably configured, energy waste can be avoided, making the energy utilization of solar street lamps more efficient.
Finally, if the solar street lamp is not maintained for a long time, dust may accumulate on the battery panel, affecting the lighting efficiency; the aging of the line will also increase the resistance and waste electricity. Therefore, we need to regularly clean the dust on the solar panel, check whether the line is damaged or aged, and replace the problematic parts in time.
I often hear people in many areas using solar street lamps complain about problems such as too short lighting time and too small battery capacity. In fact, the configuration only accounts for one aspect. The key is how to rationally set the controller. Only reasonable settings can ensure more sufficient lighting time.
