Speaking of color temperature, I believe many people in the lighting industry are familiar with it, because it is one of the most basic lighting knowledge.

How is it defined online:

"When a black body is heated to a temperature and the color of the light emitted by it is the same as the color of the light emitted by a light source, the temperature at which this black body is heated is called the color temperature of the light source, which is the color temperature."

Color temperature is closely related to life, the application of color temperature is very common around us, and almost everyone can touch it.

The picture above is the most intuitive way of expressing color temperature (temperature). The light of a match is warm light, and the light of a gas stove is cold light.

Therefore, we can define the color temperature as:

Color temperature is a phenomenon that describes the corresponding change in color when the temperature of an object changes. Using Kelvin (K) as the unit of color temperature calculation, it can be simply understood as "the color temperature change of light."

We generally divide the color temperature of the light source into three categories:

1. Warm color light

The color temperature of warm light is generally below 3000K, which is similar to that of incandescent light, with more red light components, giving people a warm and comfortable feeling;

2. Warm white light

Its color temperature is around 4000K, which will make people feel happy, comfortable and peaceful;

3. Cool light

Its color temperature is about 5500K~6500K, the light source is close to natural light, it has a bright feeling and can make people concentrate.

Choose color temperature according to environment

In fact, color temperature affects all aspects of our lives. For example, western restaurants generally choose low color temperature.

The warm color make us feel romantic. For restaurants that want to create a comfortable and relaxing atmosphere, it is more appropriate to choose a low color temperature light source regardless of the level of illumination.In addition to restaurants, bookstores, home furnishings, hotels, etc., can all use low color temperature light sources.

Of course, these areas can also be selected according to personal preference.

But not all places are suitable for warm light. For high-precision work places like office environments, the color temperature needs to be brighter, so that employees can work more concentratedly.

For high-precision work areas such as factories, hospitals, conference rooms, and teachers, it is recommended that the color temperature be around 4000K.
