"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 We express this with the Kelvin value. As the Kelvin value increases, the color temperature decreases. For example, 2200 Kelvin is a warm light color, while 6500K is a cool color.
- [°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 color is very warm. amber It has a name.
- Light emitted at a temperature of 1700–1800 Kelvin produces reddish hues, mimicking the natural light of sunrise and 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
Throughout our lives, we find ourselves in various living spaces. Because lighting has an impact on human psychology, these spaces need to be illuminated with appropriate color temperatures. Warm white colors should be preferred in relaxation areas such as living rooms, bedrooms, and restaurants. In workspaces such as offices, classrooms, workshops, or repair shops, cool white lighting should be used.
From hottest to coldest; 2200K, 2700K, 3000K, 4000Kwhich emits light at colour temperatures such as 5000K or 6500K. LED fixtures There are also models that produce light in special colors such as amber, red, green, and blue.
