Πώς να ελέγξετε τη θερμοκρασία χρώματος ενός γραμμικού φωτιστικού LED

I believe that you have a certain understanding of the technical term "color temperature". In fact, the color temperature is to heat a blackbody to a certain temperature point. When the color of light emitted by it is the same as that of light emitted by light source, the heating temperature of black body is called color temperature, commonly known as color temperature.

In the past, our lighting used mainly white woven lamps. If the color difference between the light sources is 150k, we can judge the color difference between them by eyes. However, the color temperature difference in the LED era is very different from that of the previous white weaving era. Obviously, it's a color that can be distinguished by the naked eye. How can data values be exactly the same without much difference? Here we will explain the lighting parameters: the relevant color temperature.

From the test data, it can be seen that this is related to color temperature, not color temperature. Is there any difference between them? of course. Color temperature refers to: when the color of light emitted by light source is the same as that of light emitted by blackbody at a certain temperature, the temperature of black body is called the color temperature of light source. In other words, only falling on the blackbody radiation line can we call it color temperature.

The LED line light is not thermal radiation, so its color may not fall on the black body radiation line, so we can only find the nearest point on this line, that is, its related color temperature.

Maybe many people will think, when the color is warm, green and red, how can we solve this problem? This is today invite our main role: color tolerance, officially appeared. The less the difference between X, y and standard light source calculated by the software of photochromic detection system, the higher the accuracy of light, the purer the color.
