Semi integrated Solar street light Features

The working principle of a solar street light is based on the utilization of solar energy to generate electricity and provide lighting in outdoor areas. What are the components of these innovative light systems?

Solar panel

When sunlight falls on the solar panel, it absorbs the energy and converts it into electrical energy through the panel. The solar panel is composed of multiple solar cells made of semiconductor materials such as silicon. These cells contain layers that create an electric field when exposed to sunlight.

Battery

The generated electrical energy is then stored in a rechargeable Lithium battery. The battery acts as an energy reservoir, storing the electricity during the daytime when the solar panel produces surplus energy. This stored energy is later used to power the street light during the night or when there is insufficient sunlight.

Light fixture

The energy from the battery is supplied to the light source, which is usually an energy-efficient LED Light. LEDs consume significantly less power compared to traditional lighting technologies, making them ideal for solar street lights. The LED light emits bright and focused illumination, providing adequate lighting for streets, pathways, or other outdoor areas.

Controller

To control the operation of the solar street light, an intelligent controller is employed. The controller regulates the charging and discharging of the battery, ensuring efficient energy management. It also includes features like light sensors to automatically switch the light on at dusk and off at dawn, as well as motion sensors to activate the light when movement is detected nearby.

Sensors

Light sensors detect ambient light levels, enabling automatic switching on/off of the street light to conserve energy and extend battery life. Motion sensors detect nearby movement, triggering increased brightness for improved safety while minimizing energy wastage. Battery level sensors monitor the charge level, optimizing charging and discharging to prolong battery life.
