Street lights, also known as street lamps, illuminate roadways, parking lots, sidewalks, and other public areas. They improve security and driving safety by enhancing vision in poor light conditions. They are often used with other traffic safety equipment to enhance visibility of equipment, obstacles, or darkened common areas. 

The primary function of street lights is to illuminate objects or areas that would otherwise be dark and out of focus at night. Street lights rely on light emitting diode (LED), incandescent, high pressure sodium, low pressure sodium, mercury vapor, metal halide, and high intensity discharge (HID) bulb technology to provide the appropriate amount, color, and temperature of light for a specific application. LED street lamps are the most current technology, offer the most amount of light for power consumption, and require minimal maintenance with longer bulb life.

Configurations

Street lights are commonly made of corrosion resistant metal such as aluminum or a strong plastic material such as high density polyethylene to be able to withstand the outdoor elements. Street lights are commonly pole-mounted, on either dedicated poles or existing utility poles.

Specifications 

The follow specifications determine the functionality of a street light.

• Power: Power consumption of the lamp. This can be an important factor for reducing total energy costs.
• Brightness: Brightness is the measure of the amount of light the lamp will be able to provide.
• Supply voltage: Supply voltage is the voltage supplied to the lamp itself to provide the power. It is important to choose a voltage that is already compatible with your current infrastructure.
• Operating temperature: The average temperature at which the lamp is designed to function. This specification is especially important for outdoor lamps.

Features 

These features provide additional utility or ease-of-use.

• Photosensor activated: The street lamp has a built-in photo sensor to make sure the lamp is only on in low light conditions.
• Integrated solar panel: The street lamp has a solar panel for either main or backup power to help reduce operational costs.
