Colo ( u r temperature )
Said light source spectral quality the most general index.
Colour temperature is defined by the blackbody radiation in the visible region, source and blackbody radiation are completely the same, the blackbody temperature is called the source color temperature.
Low color temperature light source is characterized by energy distribution, red radiation relative to more, often referred to as" warm light";
Color temperature increase, the energy distribution, blue radiation increased the proportion of, often referred to as" el".
Some of the commonly used light source color temperature:
Standard candle for the 1930K ( Kelvin temperature unit );
Tungsten filament lamps for 2760-2900K;
Fluorescent lamp for 3000K;
The noon sunlight for 5400K;
Electronic flash 6000K;
Source color temperature, color is different, bring the feeling is not the same:
< 3300K warm ( reddish white ) stable, warm
3500-5000K intermediate ( white ).
> 5000K cool ( bluish white ) cold
LED Light Color temperature:
Pure White: 6000-7000K, Warm White: 3000-3500K
