LED color temperature common sense and light source LED color temperature contrast table

From:Yulu science Technology    Date2018/2/28 16:23:18
An important specification number in LED products is color temperature, which is related to the color characteristics shown in LED lighting and lighting products. The general lamps and lanterns also have color temperature specifications. Color temperature level measurement unit is based on KelvinScale, which is based on K as a unit, started in the steel plant Kjeldahl observed dissolved metals to the highest temperature, the shiny metal presented a different color, and the unit of data recorded, then produce LED color temperature specifications.
Definition of color temperature: in terms of absolute temperature K, which is a standard blackbody heating, the temperature rises to a certain extent the black color to red - Orange - red - white - blue, gradually changed, a light source and the blackbody with the same color, the absolute temperature blackbody called when the temperature of the light.
Two, color temperature in different light environment:
The following is the color temperature contrast table used in general common LED lighting lamps and lanterns:
Halogen lamp 3000K tungsten lamp, 2700k high pressure sodium lamp, 1950-2250k candle light 2000K metal halide lamp, 4000-4600k cold light camp lamp, 4000-5000k high pressure mercury lamp, 3450-3750k warm color fluorescent lamp, 2500-3000k, clear air 8000-8500k, cloudy day, summer sun, afternoon sunlight, afternoon sunlight.
Three, LED light color of light due to illumination at different color temperatures:
1, low color temperature: the color temperature is below 3300K, the light color is red, giving a warm feeling, a steady atmosphere and a warm feeling. When using low color temperature source, it can make the red more vivid.
2, the middle color temperature: the color temperature is in the middle of 3000--6000K, the human has no obvious visual psychological effect under this tone, and has a refreshing feeling, so it is called "neutral" color temperature. When the medium color temperature light source is irradiated, the blue has a cool feeling.
3, high color temperature: the color temperature exceeds 6000K, the light color is blue, giving the people the feeling of cold, when using the high color temperature light source, the object has the cold feeling.
