Description

Lighting device

The present disclosure relates to a lighting apparatus, and more particularly to an LED lighting apparatus.

Street lights are installed along roads for street lighting, traffic safety or aesthetics. Depending on their characteristics, various types of light sources such as high-pressure mercury lamps, sodium lamps, fluorescent lamps, and general light bulbs are installed and used.

High-pressure mercury lamps and sodium are the most commonly used light sources for street lamps. Mercury lamps have high brightness and low power consumption compared to incandescent lamps, but they take a long time to light up and stabilize.
