Are LED light used for street?

street lights offer many advantages. They are sustainableandcost-efficient because they last longer and consume less energy than their conventional equivalents such as incandescent, halogen or fluorescent lights. Below are some benefits of LED street lights and led public lighting.

How Efficient of LED street light

Energy efficiency: LED fixtures use 50% to 75% less energy than traditional high-pressure sodium vapor fixtures. Reliability: Most LED streetlights have an expected life of 20 years and can be expected to maintain up to 90% of their light output over that time.

How do LED street light Turn on

So when light shines on the photocell, it turns the transistor on, which energizes the relay's electromagnet, which turns the light off. When it is dark, the photocell has high resistance, so no current flows through the base and the relay is not activated -- the light is on.

How long do LED street light last

How long do LED's typically last? The life span of the selected LED is designed to operate for around 100,000 hours, which is significantly (around 6 times) longer than that of most incandescent, fluorescent or High Intensity Discharge (traditional street lighting) lamp
