CRI 90 cold light source is not a perfect value, in fact it only reflects the high CRI LED cold light source of a medium LED cold light color saturation, color and high CIR cold light source close to the best blackbody radiation trajectory, and CRI 90 cold light source color temperature is neither too high nor too low. In addition, CRI 90 cold light source is not a universally applicable standard, although the high CIR cold light source incandescent lamp for the ideal value of 100.

 but if you try to recognize the deep blue, people will know the incandescent lamp is not ideal. Because of the lack of blue spectrum in the spectrum of the high CRI LED cold light source. For blue, high CIR cold light source is a better choice, but if the observation of deep red, then the same partial blue color of the high CIR cold light source e may not be the best choice. In fact, the color of the high CRI LED cold light source, no single color for the entire range of the spectrum identification is the ideal. People need to try to make a measurement standard, so that the color performance index can be applied in the most common areas

Recently, the introduction of the high CRI LED cold light source (especially LED) has made people more carefully examine the key points in the definition of the CRI 90 cold light source. The design of CRI 90 cold light source of this standard is not a RGB high CRI LED cold light source of white light, if the high CRI LED cold light source used in LED, may be misleading. Due to the lack of a large number of LED RGB yellow spectrum, so they are very poor color of yellow, but can still get a good high CRI LED cold light source e.

As is known to all, the high CIR cold light source has the potential to save energy, but it may restrain the market acceptance. With high CRI LED cold light source wavelength and the bandwidth of the subtle changes in the effects of color may be on the combined high CIR cold light source, therefore, to develop the use of these lamps of high CIR cold light source R & D personnel need an effective measure to evaluate the color of products the. Look similar to the RGB combination of high CRI LED cold light source value of the range can be from a very poor 40 to very good 80, not the same. Even with these values, whether they really represent the high CIR cold light source color is good or bad, it needs further study.
