Believe all lines of the led lamp "color temperature" has also a certain understanding of the technical term, 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.

Let's take a look at the picture above, everyone can discern the basic color is difference between left and right, right is obviously than left to slant a bit green, and you guess what is the color temperature between them respectively? Is there a difference of 150K?

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.

(1) look at the label on the lamps and lanterns, general and normal line lamp manufacturer will label before delivery of lamps and lanterns indicated the specific parameters of the product, we can through the tag to see the line lamp voltage is used by many volts.
