What causes LED lights to fail?

Temperatures are too high (or too low) LEDs shouldn’t be placed in tightly enclosed fixtures unless they’re approved for enclosed spaces. When heat can’t dissipate from the heat sink, it can cause lamps to fail prematurely. Because LEDs emit light that decreases exponentially as a function of time and temperature.

Why do LED lights stop working?

However, they can still be damaged due to the burning of other components (except for the led chip) due to negative reasons from the current and installation. Heat buildup, screwing bulbs too tightly, or placing LEDs in improper electrical circuits and accessories are common causes of LEDs stopping working.

What are the benefits of LED street lights?

Below are some of the benefits of using LED street light bulbs: LED lights depreciate at a much slower rate than other alternatives. They are light-emitting diodes, so they do not have filaments or burn out quickly (they have incredibly long lives) No toxic chemicals like mercury. Reduced maintenance costs.

What is bad about LED lights?
