What is Kelvin?

"CCT", which stands for "Correlated Colour Temperature" in English, means "Correlated Colour Temperature" in Turkish. It determines the colour value of light. Any object whose temperature is constantly increasing will glow. It even turns into colours such as blue, orange or yellow depending on the temperature level. So what is Kelvin? The colour temperature is known as the temperature value in Kelvin of the object that takes a colour close to the colour of the resulting light.

Kelvin is the unit of temperature indicated by the letter "K" in physics. 0℃= 273.15 K. In LED technology colour temperature kelvin is expressed by. As the Kelvin value increases, the colour temperature cools. For example, 2200 Kelvin is a warm light colour while 6500K is a cool colour.

• [°K] = [°C] + 273,15

Colour Temperature (Kelvin) Values

The expression colour temperature is often used in lighting projects or specifications while passing through sectors such as photography, advertising, publishing. As the Kelvin value decreases, the light colour approaches the red-orange mixture, and as it increases, it approaches the white-blue mixture. 2700 - 3500 K range is referred to as warm white, 3500 - 4000 K range as natural white and 4500 - 6500 K range as cold white. What is colour temperature or Kelvin? Let's elaborate further for the question.

• The 1500 - 1700 Kelvin range has received a special name. This colour is quite warm. amber is referred to as.
• The range 1700 - 1800 Kelvin is similar to the reddish light at sunrise or sunset.
• The range 2400 - 3500 Kelvin is similar to the warm white colour of incandescent filament lamps.
• 4500 - 6500 Kelvin range, similar to daylight and very close to white.
• Above 6500 Kelvin are tones more reminiscent of blue than white.

Colour Temperature (Kelvin) Selection in Living Spaces

We are in different living spaces throughout our lives. Due to the effects of lighting on human psychology, these places should be illuminated with appropriate colour temperatures. Warm white colours should be preferred in resting areas such as living rooms, bedrooms, restaurants. In working areas such as offices, classrooms, workshops or workshops, cold white light should be used.

From hottest to coldest; 2200K, 2700K, 3000K, 4000Kwhich emits light at colour temperatures such as 5000K or 6500K. bar LED models are available. In addition, models that produce light in special colours such as amber, red, green and blue are also among the options.
