LED color temperature common sense and LED color temperature comparison table
In LED products, an important specification number is the color temperature, which is related to the color characteristics displayed by LED lighting products. The general lamps also have color temperature specifications. The color temperature measurement unit is based on KelvinScale, that is, in K. At the beginning, when Kelvin observed that the dissolved metal began to reach the maximum temperature in the steel plant, the color of the metal was different, and it was recorded in data units. Later, a specification sheet of LED color temperature was produced.led bulb light
First, the definition of color temperature:
Expressed in absolute temperature K, that is, the standard black body is heated, and the temperature of the black body begins to dark red-light red-orange-white-blue when the temperature rises to a certain extent, and gradually changes. When the color of a light source and the black body are the same, we put The absolute temperature of the black body is called the color temperature of the light source.led flame bulb
Second, the color temperature under different light source environment:
The following is a color temperature comparison table used by common LED lighting fixtures:
Halogen lamp 3000k, tungsten lamp 2700k, high pressure sodium lamp 1950-2250k, candle light 2000k, metal halide lamp 4000-4600k, cool color camplight 4000-5000k, high pressure mercury lamp 3450-3750k, warm fluorescent lamp 2500-3000k, Clear sky 8000-8500k, cloudy day 6500-7500k, summer noon sunshine 5500k, afternoon daylight 4000k.led flood light
Third, the LED color under different color temperatures:
1. Low color temperature: The color temperature is below 3300K, the light color is reddish to give a warm feeling; there is a steady atmosphere, warm feeling; when using low color temperature light source, it can make red more vivid.led tube light
2, medium color temperature: color temperature is in the middle of 3000--6000K, people have no obvious visual psychological effect under this color tone, have a refreshing feeling; so called "neutral" color temperature. When illuminated with a medium color temperature source, the blue color is refreshed.led ceiing ight
3, high color temperature: color temperature is more than 6000K, light color is blue, giving people a cold feeling, when using high color temperature light source to make the object have a cold feeling.
