The light source of solar street light is a kind of renewable and environmentally friendly energy, which is endless and has no pollution and radiation to the environment. If solar street lights are used in residential quarters, it can reduce the cost of the property and the expenses of the owner. So which is better between solar street lights and ordinary street lights? In response to this problem, the following is the sharing of the editor of Century Sunshine Lighting:
1. Working principle:
①The working principle of solar street lights is that the solar panels collect sunlight, and the effective lighting time is from 10:00 am to 4:00 pm (take the northern summer as an example), convert the light energy into electrical energy, and store the electrical energy through the controller to In the prefabricated gel battery, when the sun goes down and the light is insufficient, so that the lighting voltage of the solar panel is lower than 5 volts, the controller will automatically activate the street lights and start lighting.
②The working principle of the 220v street light is that the main line of the street light is connected in series from the ground or underground in advance, and then connected with the street light line, and then the time controller is used to set the lighting time of the street light, when it is on and when it is off.
2. Scope of application:
Solar street lights are suitable for areas where power resources are scarce. Due to factors such as the environment and construction difficulties in some areas, solar street lights are a more appropriate choice in this case. There are also some rural and highway center isolation belt areas. In this case, the main line is overhead. If it is exposed to the sun, thunderstorms and electric shocks, etc., it is easy to cause damage to the lamps or excessive aging of the wires and cause the circuit breaker. If you go underground, you will also need high pipe jacking costs. At this time, solar street lights have become the best choice. Similarly, in areas with sufficient power resources and convenient line connections, 220v street lights are a good choice.
3. Service life:
In terms of service life, if LED street lights are used, under the condition of the same brand and the same quality, 220v street lights have a slight advantage, because LED street lights themselves are very energy-saving. No electricity bill is required, but the cost of replacing the battery every 5 years or so is much higher than the electricity bill for 220v AC street lamps (only for LED lamps, except for high-pressure sodium lamps).
Fourth, the configuration of lamps:
Whether it is AC 220v street light or solar street light, now the mainstream LED light source, because this light source has the advantages of energy saving, environmental protection, long life, etc. 60w - 120w energy-saving lamp brightness).
5. Their respective characteristics:
Features of solar street lights ① Every 10 years or so, the battery must be replaced. ②Affected by cloudy and rainy days, the battery with general configuration will be exhausted after 3-5 days of continuous cloudy and rainy days, and it will no longer be able to provide night lighting. ③The lighting time at night cannot be adjusted online in a unified way (the lighting time in winter and summer is very different, when you need to change the time, you need to adjust it one by one). Disadvantages of 220v AC street lights: ① The current of the LED light source cannot be adjusted, resulting in full power for the entire lighting period, and full power is still used in the second half of the night when there is no need for much lighting brightness, wasting energy. ②As long as there is a problem with the main cable of the lamp, it is difficult to deal with it (underground and overhead are very troublesome). If there is a short circuit, it must be checked one by one. If it is light, it can be connected and repaired. If it is serious, the entire cable needs to be replaced. ③Because the light poles are mainly steel and have strong electrical conductivity, if the electricity is connected on a cloudy and rainy day, the 220v voltage will endanger life and safety.
