Solar

 

The solar street lights can also be used at public parks and in your private lawns and gardens. They will start to automatically light up after the dusk settles in.

The power with which Solar Street Lights operate might range from 20 to 200 Watts these solar street lamps work well under temperatures ranging between 25 and 65 degree Celsius.

Sunlight is received by the photoelectric panels during daytime and solar cells convert the solar energy into electrical energy. The solar panels have adequate number of solar cells to perform this job of converting the energy derived from sunlight into electrical energy. These processes make solar street lamps a reliable and effective technology that is easy to install, energy efficient, compatible with various environments, consistent in working, long lasting, low in maintenance, etc.Light-Emitting Diode (LED) Street Lights

 

                                                                                      

 

Advantages:

  • Very long life

  • Reduced maintenance costs due to longlifetimes

  • Do not contain toxic chemicals (e.g., mercury)

  • No warm up needed (no time delay to reachoptimum brightness levels)

  • No production of ultraviolet light (which is what attracts insects)

  • Useful for directing light on specific areas, sincethey produce “directional” light -- light emitted in one direction, rather than a diffused glow

  • Can be dimmed (unlike CFLs), allowing for flexibility in controlling light levels

  • High color index, providing bright, true colorsduring nighttime hours

  • No glare effect, reducing visual fatigue for both drivers and pedestrians

In Solar LED Lighting, solar energy is used to charge a self-contained battery during daylight; at night, the battery powers the street lights. Solar LED street lighting is an especially cost-effective solution for parking lots, parks, residential streets, airports, and other applications where providing electricity is expensive or problematic. Two additional benefits of these types of LEDs is ease of installation - since the lamps rely on solar power, there is no need to dig trenches to lay underground cables - and immunity to power outages.
