Solar street lamp is a kind of lighting tool which can be used by solar photovoltaic. As long as the sunlight is sufficient, it can be installed on the ground and so on. Because it does not pollute the environment, it is called green environmental protection product. The solar street lamp is installed in the outdoor and is influenced by natural factors. So the street lamp is considered in the design stage to ensure its quality and reliability. The factors affecting the life of the solar street lamp are mainly the following several factors:
1. The light source on the solar street lamp
The general road light source has low pressure sodium lamp, low voltage non pole lamp, LED lamp and so on. The solar street lamp is used by the LED light source. The largest feature of the LED light source is that the life span is up to 50000 hours. If a day is used for 10 hours, the life span is at least 10 years, and the LED light source is more expensive than the ordinary light source, but it is reliable.
2, the controller used for the solar street lamp
The function of the solar controller is to control the charging of solar panels and the lighting of solar street lamps. A stable solar controller plays an important role in battery life.
3. The use of battery for solar street lamps
The quality and performance of the battery directly affects the life of the street lamp, the general selection of the battery is more stable, so the price will be more expensive than the battery of the ordinary manufacturer, and the good storage battery is used for a long time.
More attention should be paid to the above points in the design of solar street lamps, which can better prolong the service life of solar street lamps.
