Solar street lights do not have to be illuminated by the sun.
Working principle of a 15W solar street light: under the control of intelligent controller, solar energy street lamp absorbs solar energy and converts it into electric energy after being illuminated by sunlight in the daytime. Solar cell module charges battery pack in the daytime, and the battery pack provides power to the LED light sources in the evening to realize lighting function.
The DC controller can ensure that the battery is not damaged due to overcharge or over-discharge, and has the functions of light control, time control, temperature compensation, lightning protection, reverse polarity protection, etc. Solar street lamp system can ensure normal operation in rainy weather for more than 15 days.
The system consists of the LED light source (including driver), solar panel, battery (including battery insulation box), solar street lamp controller, street lamp pole (including foundation) and auxiliary material wire.
Advantages of 15W solar street light:
1. Energy-saving and environmental protection
The biggest advantage of solar street lamp is energy saving. This kind of product can transform the sunlight in nature into its own energy, which can reduce a lot of power consumption. Now, after the construction and development of the city, there is more investment in street lamps. The application of solar street lamps saves a considerable amount of electric energy for the country every day. The inherent characteristics of solar lighting, such as safety without hidden dangers, energy-saving without consumption, green environmental protection, simple installation, automatic control and maintenance-free, will directly bring obvious advantages for the sales of buildings and the construction of municipal engineering.
2. Safe and reliable
The use of the product is very safe. Before there were many hidden dangers of urban street lamps, some of which were caused by the construction quality not up to the standard, some of which were caused by the aging of materials, or the power supply was out of order. However, we have to admit that the street lamps supplied by the power consumption did have a certain bad impact on people's life.
The solar street lamp is a kind of product that does not need to use alternating current. It uses a high-tech battery which can absorb solar energy and automatically convert it into the required electric energy. It has very high safety performance.
3. Low installation and maintenance costs
The operation and maintenance cost of solar street lamp is low. In addition to a small part of the cost of electricity, the operation cost of solar street lamp is almost zero. The operation of the whole system is automatic control, without human intervention and almost no maintenance cost.
