Technology | LED color temperature common sense and LED color temperature comparison table

82 views admin 2022-08-19

Sunrise LED believes that in LED products, an important specification number is color temperature, which is related to the color characteristics displayed by LED lighting products. General lamps also have color temperature specifications. The unit of measurement of color temperature is KelvinScale, that is, K. At the beginning, when Kjeldahl observed in the steel plant from the beginning of dissolving metal to the highest temperature, the color of the metal luminous was different, and it was recorded in data units. Later, a specification sheet for LED color temperature was produced.

1.Definition of Color Temperature

It is expressed by absolute temperature K, that is, the standard black body is heated. When the temperature rises to a certain level, the color of the black body starts to be dark red-light red-orange-yellow-white-blue, and gradually changes. When a light source is the same color as the black body, we put The absolute temperature of the black body is called the color temperature of the light source.

2.Color temperature under different light sources

The following is a color temperature comparison table for common LED lighting fixtures:

Halogen 3000k

Tungsten filament lamp 2700k

High Pressure Sodium Lamp 1950-2250k

Candle Light 2000k

Metal Halide Lamp 4000-4600khutou.com

Cool color fluorescent lamp 4000-5000k

High pressure mercury lamp 3450-3750k

Warm color fluorescent lamp 2500-3000k

Clear sky 8000-8500k

Cloudy 6500-7500k

Summer Noon Sunshine 5500k

Afternoon Daylight 4000k

Warm white light 4000K

Positive white light 6500K

1. Low color temperature: the color temperature is below 3300K, and the light color is reddish to give a warm feeling; there is a stable atmosphere and a warm feeling;

When irradiated with a low color temperature light source, the red color can be more vivid.

2. Medium color temperature: The color temperature is in the middle of 3000--6000K. People have no particularly obvious visual psychological effect under this color tone, and they have a refreshing feeling: so it is called "neutral" color temperature. When irradiated with a medium color temperature light source, the blue color has a cool feeling.

3. High color temperature: The color temperature is more than 6000K, and the light color is bluish, giving people a cool feeling. When a high color temperature light source is used, the object will feel cold.
