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

What are the color temperatures of table lamps? How to distinguish the color temperature of a desk lamp? What I recommend to you today is these two aspects of knowledge. Therefore, the common color temperatures of desk lamps can be classified according to the corresponding standard parameters in different countries. For example, China's national standards stipulate the color temperature parameters corresponding to warm tone, positive white tone and cold tone. Furthermore, today we also give some points for attention in the process of choosing the color temperature of lights. It can be seen that the color temperature corresponding to different weather and the suitable color temperature in different places are completely different. If necessary, you can refer to this part of knowledge and consider designing a suitable color temperature yourself.

1. What are the color temperatures of the desk lamp?

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.

The above recommendation is an introduction to the classification knowledge about the color temperature of desk lamps. Therefore, in different weather, the corresponding color temperatures of different scenes are completely different. The common color temperature can be divided into three sections, including warm color, positive white color and blue color, and their corresponding populations are very different. In addition, the so-called color temperature, if properly adjusted, can effectively make up for some defects in real life. For photographers or friends who work for a long time, it can also achieve satisfactory results. Interested consumers and friends may wish to know about it and refer to the above together.
