What happens when led lights fail?

LED lighting is a rare and no pollution green light, made up of solid state semiconductor devices, and it can turn electrical energy into light. read more

Unlike an incandescent lamp, where failure is fairly simple (the bulb produces light until the filament breaks), with an LED, the failure modes range from mechanical and electrical to material. Still there are some branded LED lights are good for house uses, Syska LED lights also good option for home. read more

Reverse bias: Although the LED is based on a diode junction and is nominally a rectifier, the reverse-breakdown mode for some types can occur at very low voltages and essentially any excess reverse bias can cause immediate degradation, and may lead to vastly accelerated failure. 5 V is a typical maximum reverse bias voltage specification for ordinary LEDs; some special types may have lower limits. read more

Martjin Dekker, CTO of Lemnis Lighting, a Dutch start-up manufacturer of LED bulbs, said failures tend to stem from a breakdown of components within the bulb other than the bulb’s LED (light emitting diode, which is a semiconductor). read more
