Medical High Display Index Cold Light Source - High Display Index Cold Light Source, Medical Device Standard Red Green Blue Light Flux Ratio

A high color rendering index cold light source is not a perfect value. In fact, it only reflects the color rendering of a small segment of medium saturation color by a high color rendering LED cold light source. Moreover, the color point of the high color rendering cold light source should be close to the blackbody radiation trajectory, and the color temperature of the CRI 90 cold light source should not be too high or too low. In addition, CRI 90 cold light source is not a universally applicable standard, although the high color rendering cold light source value of incandescent lamps is ideally 100

But if one tries to distinguish between different shades of dark blue, people will know that using incandescent bulbs is not ideal. Because the spectrum of high color rendering LED cold light source lacks blue spectrum. For blue, a high color rendering cold light source is a better choice, but if observing deep red, a high color rendering cold light source with the same bluish hue may not be the best choice. In fact, no single color temperature high color rendering LED cold light source is ideal for color recognition across the entire spectral range. People need to try to develop a measurement standard that can make color rendering performance indicators applicable in the most common fields

As is well known, high color rendering cold light sources have great potential for energy conservation, but their lack of color rendering may suppress their market acceptance. Minor changes in the wavelength and bandwidth of the high color rendering LED cold light source used may have a significant impact on the color rendering of this combination of high color rendering cold light sources. Therefore, researchers using these high color rendering cold light sources to develop lighting fixtures need an effective measurement standard to evaluate the color rendering of the product. The CRI values of LED fixtures with similar RGB combination high color rendering cold light sources can range from a very poor 40 to a very good 80, which is not exactly the same. Even with these values, further exploration is needed to determine whether they truly represent the quality of high color rendering cold light sources.
