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.

SPECIFICATION
LIGHT SOURCE
 
  1. The light source will be a white LED
  2. The color temperature of white LED used in the system should be in the range of 5500oK–6500o
  • W-LEDs should not emit ultraviolet
  1. The light output from the white LED light source should be constant throughout the duty
  2. The lamps should be housed in an assembly suitable for outdoor
  3. The temperature of heat sink should not increase more than 20oC above ambient temperature during the dusk to dawn
 

ELECTRONIC PROTECTIONS

 
  1. Adequate protection is to be incorporated under “No Load” conditions g. when the lamp is removed and the system is switched ‘ON’.
  2. The system should have protection against battery overcharge and deep discharge
  • The System should have protection against short circuit conditions.
  1. Protection for reverse flow of current through the PV module(s) should be
  2. Adequate protection should be provided against battery reverse
  3. Load reconnect should be provided at 80% of the battery capacity
 

INDICATORS

 
  • The system should have two indicators, green and red.
  • The green indicator should indicate the charging under progress and should glow only when the charging is taking place. It should stop glowing when the battery is fully
  • Red indicator should indicate the battery “Load Cut Off”
 

QUALITY AND WARRANTY

 
  1. The street lighting system (including the battery) will be warranted for a period of two to five years from the date of supply mutation on invoice.
