Common sense of LED color temperature (colo(u)r temperature):

　　 Color temperature is the most common index that represents the spectral quality of a light source. The color temperature is defined by the absolute black body. When the radiation of the light source in the visible region is exactly the same as that of the absolute black body, In-Line Led Lantern the temperature of the black body at this time is called the color temperature of the light source. The characteristic of the low color temperature light source is that in the energy distribution, red radiation is relatively more, usually called "warm light"; after the color temperature increases,Tricolor Light Emitting Diode the proportion of blue radiation in the energy distribution increases, usually called "cold light". The color temperature of some commonly used light sources is: standard candle light is 1930K (Kelvin temperature unit); tungsten lamp is 2760-2900K; fluorescent lamp is 3000K; flash lamp is 3800K; noon sunlight is 5400K; electronic flash lamp is 6000K; blue sky is 12000-18000K. General definition, warm white temperature: 2700-3200K, normal white: 4000-4500K, daylight white: 6000-6500K, cool white: above 6500K Red Light Emitting Diode.
