To generate white light best suited as an LCD backlight, parts of the light of a blue-emitting LED are transformed by quantum dots into small-bandwidth green and red light such that the combined white light allows a nearly ideal color gamut to be generated by the RGB color filters of the LCD panel. The quantum dots may be in a separate layer as ...
As for other consumer electronics products (e.g., fridges or light bulbs), energy consumption categories are enforced for television sets. [35] Standards for power ratings for TV sets have been introduced, e.g., in the USA, EU, and Australia [ 36 ] as well as in China. [ 37 ]

Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications, such as cove lighting .
For example, the top bulbs listed in the 2016 Consumer Review have a CRI of 80. [3] In 2008, the U.S. Department of Energy created the L Prize to find an incandescent light bulb replacement that met efficiency metrics and had a CRI above 90.

Dimming fluorescent ballasts and dimming LED drivers often use 0–10 V control signals to control dimming functions. In many cases, the dimming range of the power supply or ballast is limited. If the light output can only be dimmed from 100% down to 10%, there must be a switch or relay available to kill power to the system and turn the light ...
