2. LED filament - Wikipedia

   en.wikipedia.org/wiki/LED_filament

   LED filaments can burn out quickly if the controlled gas fill is ever lost for any reason. The power supply in a clear bulb must be very small to fit into the base of the lamp. [8] The large number of LEDs (typically 28 per filament) simplifies the power supply compared to other LED lamps, as the voltage per blue LED is between 2.48 and 3.7 ...

   en.wikipedia.org/wiki/List_of_LED_failure_modes

   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 ...

4. Thermal management of high-power LEDs - Wikipedia

   en.wikipedia.org/wiki/Thermal_management_of_high...

   LED power dissipation is modeled as a current source; thermal resistance is modeled as a resistor; and the ambient temperature is modeled as a voltage source. High power light-emitting diodes (LEDs) can use 350 milliwatts or more in a single LED. Most of the electricity in an LED becomes heat rather than light – about 70% heat and 30% light. [1]

7. Holiday lighting technology - Wikipedia

   en.wikipedia.org/wiki/Holiday_lighting_technology

   Since they are constructed from solid state materials and have no metallic filaments to burn out or break, LEDs are much less susceptible to breakage from impact or rough handling. [2] [citation needed] Although LEDs are long-life devices, older or lower-quality strands of LED-based holiday lights can suffer from early failure.
