Dc Street

A street light, light pole, lamppost, street lamp, light standard, or lamp standard is a raised source of light on the edge of a road or path. Modern lamps may also have light-sensitive photocells that activate automatically when light is or is not needed: dusk, dawn, or the onset of dark weather.

This function in older lighting systems could have been performed with the aid of a solar dial. Many street light systems are being connected underground instead of wiring from one utility post to another.

 

OPERATION

 

Photocells detect if light is needed. Photocells are light-sensitive sensors that respond to the amount of light detected. When the light is too low, such as at dusk or under heavy overcast skies, the sensor tells the computing unit within the streetlight to activate the flow of electricity. When the photocell detects too much light, the sensor will deactivate the streetlight.

 

SALIENT FEATURES

 

Your light will be sitting outside exposed to elements. Therefore, the innards of your light (viz. the LED Chips, Driver, etc) must be adequately protected against moisture and dust.To a minimum, your light fixture must be IP65 compliant. This means it has dust and water protection. If you stay close to coastal areas, also consider if the light is safe against the corrosive salty sea winds.

 

ADVANTAGES

 

  • Major advantages of DC street lighting include prevention of accidents and increase in safety.
  • Since external wires are eliminated, risk of accidents are minimized
  • DC Solar street lights require much less maintenance compared to conventional street lights.
