Color Temperature

Color temperature and Kelvin unit in indoor lighting

Kelvin is a measure of temperature that was named after the efforts of scientist William Thomson (known as Lord Kelvin).

Lord Kelvin was searching for a temperature where all particles are fixed and do not move, which he finally managed to find after many different experiments; The temperature of -273 degrees Celsius, which was introduced to the world as zero Kelvin or absolute zero Kelvin.

In converting Celsius to Kelvin, you must add 273 units to the degree value in Celsius; For example, 12 degrees Celsius is an average of 285 Kelvin.

Mr. Thomson announced a range for his own conclusions; The range of 1,000 to 10,000 Kelvin, which caused the metal to shine in one of the colors of visible light, and called this parameter Color Temperature.

So that the closer this number is to the lower limit (1000 Kelvin), you will have red light, and the higher it is (10.000 Kelvin), you will have blue light.

Lights less than 3300 Kelvin are called "warm white".

Lights between 3,300 and 5,300 Kelvin are called "medium white" or "natural" light.

And finally, lights above 5300 Kelvin to 7000, which are known as "cool white" and are reminiscent of daylight.

At interior design and creating a suitable atmosphere, the color and temperature of light are very important.

Assuming, for example, a light temperature of 4500 for residential spaces, it creates a sunny and balanced light.

Note that in the settings section of 3D software, you can specify the temperature of the lights by choosing the Kelvin unit.
