The color temperature is the black body and the different colors produced by different temperatures. The color temperature of the light source is determined by comparing its color with the theoretical thermal blackbody radiator.
In fact, the color temperature can be simply understood as the temperature of the color. Let's take a look at the different degrees of color temperature:
Different color temperatures correspond to different colors, so the approximate temperature can be judged by the color. For example, metal workers can judge the temperature of molten iron based on the color. The human brain has different performances at different color temperatures: it will be more energetic under high color temperature (daytime) lighting, and will be calmer under low color temperature lighting.
Some common examples in life: 1700K: match light, flame 1850K: candle light, sunset and sunrise 2550K: Incandescent lamp (tungsten lamp) 3000K: Common color temperature of halogen lamps and yellow light lamps 3200K: Studio lights 3350K: Studio CP light 4000K: natural light, moonlight, light yellow fluorescent lamp 5000K: horizon daylight 5500K: Electronic flash, average daylight 6000K: positive white light 6500K: Common white light fluorescent lamp color temperature 6500K-9500K: LCD, CRT screen 15000K-27000K: clear blue sky
Our main application of color temperature is the most common aspects such as sunlight, lighting, photography and so on.
When purchasing lighting fixtures, color temperature is generally involved. The color temperature range of normal lighting fixtures is:
Around 3000K: warm color light Around 4000K: warm white light 5500K-6500K: positive white light
The specific choice can be selected according to the purpose, location and own visual experience. Choosing the right color temperature is very helpful for the atmosphere and visual effects of the whole room. For example, when you sleep, you should not choose a bright color temperature. You should choose a warmer color temperature. Therefore, the warm color of the night light is the ideal color temperature that is helpful to calm the brain. 4000K is between 3000K warm yellow light and 6000K positive white light. The relative feeling is not good. It will be too depressing and dazzling.
