Cool White Led Spectrum

Manufacturers produce white leds with outputs classed as warm white 2600 to 3700 k cct neutral white 3700 to 5000 k cct and cool white 5000 to 8300 k.

Cool white led spectrum.

The terms warm white and cool white are references to the low and high end of this white light colour spectrum. The result of poor color spectrum is that some colors won t even be present even though it appears to us as white. The three primary types of color temperature for light bulbs are. A power led i have emits yellow and purple to attain a cool white.

The range of color temperature. Technically led chips can be made to emit a specific light colour and from the red blue yellow and pure white light spectrum. The system is a mercury free alternative that is safer more controllable and precise than traditional bulb illumination options. Warm white has more red in it.

Cool white leds emit more blue and the radiation is classified as hotter although again humans have an alternative perception that determines the light is cooler. In short though the color spectrum of white leds is generally horrible unless you get a really expensive one designed for full spectrum use. It is impossible to reliably manufacture leds of exactly the same color. Soft white 2700k 3000k bright white cool white 3500k 4100k and daylight 5000k 6500k.

This is why led technology is applied to various applications. In general white leds consist of two ish spikes of color in the spectrum with everything else very low in comparison.
