What is the difference between full-spectrum LED lights and ordinary LED lights?

① The full spectrum is not necessarily made of purple LED + red, green and blue phosphors. Blue chips + special phosphors can also achieve the so-called full spectrum.

② Whether the blue energy is high or not (the height of the blue peak) is also affected by the color of the light. For example, if the blue LED has a low color temperature of 3000K or lower, the blue peak will actually be very low.

Then briefly explain the full spectrum: it should be said that there is no very clear definition of the full spectrum. Generally speaking, it can be regarded as a full spectrum if it is close to imitating sunlight. The scientific definition of the color rendering index of the light emitted by the sun is 100. Some manufacturers call the CRI higher than 95 full spectrum. But you must know that sunlight is not only seven-color visible light, but also infrared and ultraviolet, so the so-called full spectrum at the moment is basically a gimmick.

Is the full spectrum useful?

The answer is yes. The color rendering index of the full-spectrum lamp mentioned above is relatively high, generally greater than 95, and the ordinary one is generally around 70 or 80. The color rendering index mainly reflects the degree of light restoration of the color of the object itself, that is, the higher the color rendering index, the more accurate the color of the object you see through this light. The state stipulates that the general lamp display index should be above 80.
