  2. Color temperature - Wikipedia

    en.wikipedia.org/wiki/Color_temperature

    CCT dimming for LED technology is regarded as a difficult task, since binning, age and temperature drift effects of LEDs change the actual color value output. Here feedback loop systems are used, for example with color sensors, to actively monitor and control the color output of multiple color mixing LEDs.

  3. Light-emitting diode - Wikipedia

    en.wikipedia.org/wiki/Light-emitting_diode

    Overdriving an LED in high ambient temperatures may result in overheating the LED package, eventually leading to device failure. An adequate heat sink is needed to maintain long life. This is especially important in automotive, medical, and military uses where devices must operate over a wide range of temperatures, and require low failure rates.

  4. High-CRI LED lighting - Wikipedia

    en.wikipedia.org/wiki/High-CRI_LED_lighting

    High-CRI LED lighting is a light-emitting diode (LED) lighting source that offers a high color rendering index (CRI). CRI is a quantitative measure of a light's ability to reproduce the colors of objects faithfully in comparison with an ideal or natural light source.

  7. 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 ...
