Service Life: LED traffic lights have a long service life, generally up to 10 years. In contrast, traditional traffic lights, such as those using incandescent or halogen lamps, have a shorter service life and need to be replaced 3-4 times a year.

Design: LED traffic lights have a different optical system planning, electrical accessories, heat dissipation measures, and structural planning compared to traditional traffic lights. The layout of the LEDs in LED traffic lights can be adjusted to form a variety of pictures, and they can integrate various colors and signal lights into one1. Traditional traffic lights are mainly composed of a light source, lamp holder, reflector, and transparent cover.

Light Utilization: LED traffic lights have a narrow emission spectrum, good monochromaticity, and do not require a filter, so the light of the light source can basically be used1. Traditional traffic lights need to use filters to obtain the desired color, so the light utilization rate is greatly reduced.

Energy Efficiency: LEDs require much less energy to create the same amount of brightness as incandescent lights.

Environmental Impact: LED street lights do not emit any infrared rays, radiation, ultraviolet rays, pollution, or harmful metals. Traditional street lights consist of harmful rays and harmful metals in the spectrum.

Cost: LED street lights tend to be more expensive than traditional street lights, but the long-term savings from their efficiency and longevity can offset the upfront cost.
