2. List of LED failure modes - Wikipedia

   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 ...

3. Phase-out of incandescent light bulbs - Wikipedia

   LED lamps radiate much less heat than other technologies, and can be either multi-directional or unidirectional, eliminating the need for a mirrored reflector in the bulb or fixture. [21] LED lamps can emit saturated colored light. Disadvantages include spectrum limitations due to discrete emission colors.

4. Light-emitting diode physics - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode_physics

   A LED is a long-lived light source, but certain mechanisms can cause slow loss of efficiency of the device or sudden failure. The wavelength of the light emitted is a function of the band gap of the semiconductor material used; materials such as gallium arsenide , and others , with various trace doping elements , are used to produce different ...

5. 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]

   One-color light is well suited for traffic lights and signals, exit signs, emergency vehicle lighting, ships' navigation lights, and LED-based Christmas lights. Because of their long life, fast switching times, and visibility in broad daylight due to their high output and focus, LEDs have been used in automotive brake lights and turn signals.

7. Why Even Interior Designers Should Embrace LED Light Bulbs - AOL

   Technological advances have now led to LED bulbs in every color, size, style, and—most importantly— temperature. These new warmer versions perfectly mimic the glow of an incandescent bulb, and ...
