The led line lamp manufacturer fengjing lighting has met the customer's question today: what is the color tolerance? What does it have to do with color temperature, and what do you mean by a lot of color coordinates and color indices? Should he pay attention to these problems when choosing lamps and lanterns?

Believe that everybody on the technical term "color temperature" also to have certain understanding, color WenJiShi is to put a black body is heated to a temperature points, the light emitted by its color and the color photograph of a lighting source heating temperature of the blackbody at the same time we call the color temperature, commonly called: color temperature.

In the past our basic is given priority to with incandescent lamp lighting, light source color temperature is between 150 k, we can judge the differences between them with our eyes, can be in the current era prevailing LED color temperature difference and white weave different times before.

It is obvious that the color can be distinguished by the naked eye, how can the data value differ a bit and not much? Here's the lighting parameter: related color temperature.

And the data that you're testing, you should be able to see, it's the correlation color temperature, it's not the color temperature, is there a difference between them? B: of course. Color temperature refers to: the color of the light emitting light and the black body at a certain temperature radiating the color phase, the black body temperature is called the color temperature of the light source. In other words, only the black body radiation can be called the color temperature.

Which LED to the light, not thermal radiation, the color of the light it may not fall in the line of blackbody radiation, the point that we can only find this online recently, there is its correlated color temperature.

But... In fact, some of the light colors emitted from the blackbody radiation line at 3000K have been deviated, but 3000K can only be described on this line.

And that's what happens:

One color is green, one is red, although it looks very different in our eyes, it is called 3000K.

Maybe a lot of people will be puzzled, the color temperature will be green a little red, how to solve? This is to ask us today's protagonist: color tolerance, formal entrance. The difference between the Y value and the standard light source is the difference between the Y value and the standard light source. The higher the value, the higher the accuracy, the more pure the color of light.
