Color Temperature And Color Of LED

Color temperature of light source:

The absolute temperature of the complete radiator, which is equal to or close to the color temperature of the light source, is used to describe the color table of the light source (the color seen by the human eye when directly observing the light source), which is also called the color temperature of the light source. Color temperature is expressed in absolute temperature K. Different color temperatures will cause people to react differently emotionally. We generally classify the color temperatures of light sources into three categories:

. Warm color light

The color temperature of warm color light is below 3300K The warm color light is similar to the incandescent light, with many red light components, giving people a warm, healthy and comfortable feeling. It is suitable for families, residences, dormitories, hospitals, hotels and other places, or places with low temperature.

Warm white light

Also called neutral color, its color temperature is between 3300K and 5300K Warm white light with soft light makes people feel happy, comfortable and serene. It is suitable for shops, hospitals, offices, restaurants, waiting rooms and other places.

. Cold colored light

It is also called sunlight color. Its color temperature is above 5300K, and the light source is close to natural light. It has a bright feeling and makes people concentrate. It is suitable for offices, conference rooms, classrooms, drawing rooms, design rooms, library reading rooms, exhibition windows and other places.

Chromogenic property

The degree to which the light source presents the color of objects is called color rendering, that is, the degree to which the color is realistic. The light source with high color rendering performs better on the color, and the color we see is closer to the natural color. The light source with low color rendering performs worse on the color, and the color deviation we see is also large.

Why is there a difference between high and low performance? The key lies in the light splitting characteristics of the light. The wavelength of visible light is in the range of 380nm to 780nm, which is the range of red, orange, yellow, green, blue, blue and purple light we see in the spectrum. If the proportion of light in the light emitted by the light source is similar to that of natural light, the color seen by our eyes will be more realistic.
