Grundlegendes zur Farbtemperatur von LEDs

Color temperature is the most common index to indicate the spectral quality of light source. The color temperature is defined by the absolute blackbody. When the radiation of the light source is exactly the same as that of the absolute blackbody in the visible region, the temperature of the blackbody is called the color temperature of the light source. The characteristic of low color temperature light source is that there is more red radiation in the energy distribution, which is usually called "warm light"; When the color temperature increases, the proportion of blue radiation in the energy distribution increases, which is usually called "cold light". The color temperature of some common light sources is: Standard candlelight is 1930k (Kelvin temperature unit); The temperature of tungsten filament lamp is 2760-2900k; The fluorescent lamp is 3000K; The flash is 3800K; The sunshine is 5400k at noon; The flash lamp is 6000K; The blue sky is 12000-18000k. General definition: warm white: 2700-3200k, normal white: 4000-4500k, sunlight white: 6000-6500k, cold white: above 6500k
