What are the color temperatures of lamps? How to choose the color temperature of light?

What are the color temperatures of lamps? How to distinguish the color temperature of LED lamp? How can we choose the color temperature of the light according to the actual situation? What I recommend to you today is the content and information of these two or three aspects. Therefore, according to different standards, the corresponding color temperature may be different. If it is based on the national standard of China, the parameters corresponding to warm white and cool color are quite different. Secondly, it should be divided according to the scale of light color of light source, and different color temperatures should be adjusted according to the actual situation. For example, the color temperature in leisure and entertainment is completely different from that in reading newspapers. In some special scenes, we can also make appropriate and reasonable customization and design based on the correlation of different light sources. I believe that we can also achieve satisfactory results. Let's take a look with Bian Xiao.

1. What are the color temperatures of lamps?

According to the national standard of China: 2700K and 3000K are warm colors; 3500K, 4200K, white; 5000K and 6400K are cool colors.

Second, how to distinguish the color temperature of led lights?

Color temperature is a measure of light color of light source, and the unit is K (Kelvin)!

In physics, color temperature means that when a standard blackbody is heated, the temperature rises to a certain extent and the color begins to change from dark red. -? Light red? -? Orange? -? White? -? Blue changes gradually. When the color of the light source is the same as that of the black body, we call the absolute temperature of the black body at that time the color temperature of the light source. Color temperature is an important application in photography, video recording and publishing! Color temperature is divided into warm white, natural white (positive white) and cold white.

The color temperature of the LED lamp refers to the color when the LED lamp emits light, which is generally divided into three types: warm white (2700K-4500K), normal white (4500 K-6500K) and cold white (above 6500 K).

Generally, the light seen by human eyes is composed of the spectra of seven colors of light. But some are blue and some are red. Color temperature is a method specially used to measure and calculate the color composition of light. How to accurately locate the color temperature? This requires the use of a "color temperature table". Under normal circumstances, from noon 10 to 2 pm, in a clear and cloudless sky, in the absence of direct sunlight, the standard sunlight is about? 5200 ~ 5500 K. The color temperature of news photography lamp is 3200 K; Generally speaking, in tungsten lamp, the color temperature of the tungsten lamp used by the photo studio to take black-and-white photos is similar to that of ordinary light bulbs? 2800K； Because of the low color temperature, the photos taken in this case will feel yellow after printing. The color temperature of ordinary fluorescent lamps is about 7200~8500 K, so the photos taken under fluorescent lamps will be cyan.

Third, how to choose the color temperature of the light?

Color temperature is a fixed value to measure the color of light, and it is the most commonly used index to express the spectral quality of light source.

Warm color light (yellow-orange) at K < 3300 >; 3300, cool (bluish), k >；; 6000 is almost white! The following are the color temperature values of various lights, which is convenient for making different light source effects!

Correlated color temperatures of different light sources.

-Clear skies in the north. Wan Li? 8000-8500k

-Is it cloudy? 6500-7500k

-The midday sun in summer? 5500k

-Metal halide lamps? 4000-4600k

Afternoon sunshine? 4000k

-Cool camp lights? 4000-5000k

-High pressure mercury lamp? 3450-3750k

Warm camping lights? 2500-3000k

Halogen lamp 3000k

Tungsten lamp? 2700k

-High pressure sodium lamp? 1950-2250k

Candlelight? 2000k

Different color temperatures of light sources lead to different light colors. The color temperature below 3300K is stable and gives people a warm feeling; The color temperature of 3000-5000K is the middle color temperature, which has a refreshing feeling; The color temperature is above 5000K, and it feels cold. Different colors of different light sources constitute the best environment.

What is recommended above is the classification and selection skills of the color temperature of lamps. From this, we can know that, first of all, the common color temperatures of lamps can be divided into three types, namely warm color, white color or cool color, and the corresponding parameters are not the same. Secondly, we all know that color temperature is a parameter to measure color. The correlated color temperatures of different light sources are different, and the applicable places are also very different. Consumers and friends should comprehensively consider the actual situation, or refer to the above professional knowledge and make timely adjustments according to their own needs. I believe this will achieve satisfactory final practical results.
