How much do you know about the color temperature of lights? - Sunshinelux

January 31, 2023

  Light varies in nature, and the perceived color of an object depends on the light source that illuminates it. The human brain can "correct" for these color variations pretty well, but the film or CCD/CMOS photoreceptors we use are not up to the task.

  If an object burns, first the flame is red, then it turns orange-yellow as the temperature rises, then it turns white, and finally, blue appears.

  Scottish mathematician and physicist lord kelvin first discovered the close relationship between heat and color in 1848, and left the world with a great concept of "absolute zero" (-273.15 degrees Celsius). Since then, the Kelvin temperature scale was created.



The Kelvin scale uses the unit K (short for kelvin) to express temperature. Taking flame as an example here, the lower the value, the more "red", and the higher the value, the more "blue". Red and blue are not the colors of the light itself, but just indicate that there are more red or blue components in the spectrum.

  Here's a look at common standards in the Kelvin scale: "Absolute zero" is represented on the Kelvin scale as 0 K, which corresponds to -273.15 degrees Celsius (or -459 degrees Fahrenheit), the temperature at which the thermal activity of a substance completely ceases.

  The bluer the light color, the higher the color temperature; the redder the light color, the lower the color temperature. The color temperature of the light source is different, and the light color is also different. The color temperature below 3300K has a stable atmosphere and a warm feeling; the color temperature between 3000-5000K is the middle color temperature, which has a refreshing feeling; the color temperature above 5000K has a cold feeling. Different light colors of different light sources form the best environment.

  Preferences in color temperature vary from person to person, which is related to the scenery we see every day. For example, in areas close to the equator, the average color temperature that people see daily is 11000K (8000K (dusk) ~ 17000K (noon)), so they prefer high color temperature (it looks more real). On the contrary, people in areas with higher latitudes (average color temperature is about 6000K) prefer  low color temperature (5600K or 6500K). It is bluish; on the contrary, if you use a TV with a low color temperature to watch the subtropical style, you will feel a little reddish.

  How is the color temperature of a TV or display screen defined? Since the average color temperature of China's scenery is between 8000K and 9500K throughout the year, the production of TV programs is based on the audience's color temperature of 9300K to shoot. However, the usual color temperature in Europe and the United States is different for us. The average color temperature in the four seasons of the year is about 6000K as a reference for production. Therefore, when we watch those foreign films, we will find that 5600K ~ 6500K is the most suitable for viewing.

  People with dark eyes see 9300K as white, but people with blue eyes see blue. At 6500K, people with blue eyes see white, while people with black eyes see yellowish.

  The lights produced by our company can customize the color temperature, mainly is about 3000K-6500K.
