For example, a green LED is sensitive to blue light and some green light, but not to yellow or red light. This implementation of LEDs may be added to designs with only minor modifications in circuitry. [10] An LED can be multiplexed in such a circuit, such that it can be used for both light emission and sensing at different times. [10] [12]
A small amount of green light, provided by another LED, could correct the problem. [38] Some products are RGBWW, i.e. RGBW with tunable white. [39] A final class of white LED with mixed light is dim-to-warm. These are ordinary 2700K white LED bulbs with a small red LED that turns on when the bulb is dimmed.
This ability to control multiple light sources from a user device allows complex lighting scenes to be created. A room may have multiple scenes pre-set, each one created for different activities in the room. A major benefit of lighting control systems is reduced energy consumption.
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 ...
An automated light, properly called a luminaire, fixture (or sometimes moving head), is a versatile and multi-function instrument designed to replace multiple conventional, non-moving lights. Depending on the venue and application, automated luminaires can be a versatile and economical addition to a stock of traditional lights because, with ...

They enable computer control via networked switches, but do not require it. Their cost is about the same as the older "dimmability" circuitry that they replace in LED bulbs, fixtures or drivers. A residential-type dimmer switch with sliding knob to change brightness. The device is small enough to fit into a regular wall box provided for a switch.
