Changhui Lighting: Preventive measures for unstable lighting time of solar garden lights Changhui

The amount of solar radiation varies due to seasonal changes. In spring and autumn, the sunshine time is relatively uniform, and the amount of solar radiation is relatively uniform, but in summer, the daytime is long and the night is short. In winter, the amount of solar radiation will change at both ends. The biggest impact should be the working time of solar garden lights. In summer, when the sun is full, the solar panel can absorb enough energy and convert it into enough electricity. In the winter, when the sunshine time is short, the solar panel can only absorb part of the energy, and the solar garden light has a short lighting time at night. The uneven distribution of solar radiation in a year is a key problem that leads to different working hours of solar lamps (aside from the automatic setting of the lighting time, here we mainly talk about the situation of lighting all night). So how to solve this problem, Changhui Lighting Technology proposes the following two solutions for reference: Changhui Lighting solar garden lights can automatically set the lighting time, and then calculate the power consumption of solar panels and batteries according to the power consumption of the lighting time. If the capacity is calculated according to the lighting time of 12 hours in winter (here is an example of lighting time), then it is dark at 8 o'clock in summer and bright at 5 o'clock, so there is no need to turn on the lights for 12 hours, which will waste solar panels and batteries. capacity, the same waste problem will be encountered in spring and autumn. If the design is based on 8-9 hours in summer, then in winter it will be dark at 5:30 and dawn at 7:00. So plan 1: Design solar garden lights according to the spring and autumn, which is enough to meet the possibility of having light all night in summer. For winter, you can add a mains complementary controller to connect the solar lights and mains together. Of course, the investment cost of the newly installed lamps will be relatively large. It is best to carry out the project of street lamp lighting renovation, as long as a set of independent power generation solar photovoltaic system is installed on the original street lamps. So how can the newly installed solar garden lights be lit all night? Option 2: In the northern winter, it can be counted as 4 and a half months, which is 5 hours shorter than the summer sunshine time. The solar garden lights are based on the winter lighting requirements. Design, half-power lighting in spring, summer and autumn, that is to say, the lighting time is designed for 12 hours in winter, and half-power lighting is performed in the remaining 4 hours in summer, which can also achieve the effect of energy saving. The two schemes of Changhui Lighting Street Lighting are both based on the analysis of energy saving and investment cost reduction.
