At present, the D65 light source lamp tube also mainly depends on import, and the traditional D65 light source synthesis method mainly adopts a halogen tungsten lamp to synthesize through a light filter, so that the light source has large volume and short service life.
At present, in the industries of cotton spinning, printing and dyeing and the like in China, a standard illuminating body is required to be utilized, and a D65 light source is one of standard light sources conforming to international standards and is widely applied to various color measurement and chromaticity measurement. However, the D65 light source has the defects of overlarge volume and short service life, so that the device is mainly applied to the situations of larger instrument volume and high measurement accuracy requirement. In many portable colorimetric measurement devices and colorimetric detection devices during production, the D65 light source is not well suited for use.
LEDs are currently common light emitting devices that have advantages of stability, energy conservation, long lifetime, short response time, no environmental pollution, etc. However, most of the existing LEDs are monochromatic light, and the existing white LEDs are also quite different from natural light. Therefore, the invention discloses a novel cotton color measuring instrument adopting an LED analog D65 light source.

As a preferable scheme of the novel cotton color measuring instrument adopting the LED analog D65 light source, the utility model comprises the following steps: the light source consists of a plurality of positive white LED lamp beads and a plurality of warm white LED lamp beads.
As a preferable scheme of the novel cotton color measuring instrument adopting the LED analog D65 light source, the utility model comprises the following steps: the color temperature range of the positive white LED lamp bead is 6000K-6500K, and the color temperature range of the warm white LED lamp bead is 2800K-3200K.
As a preferable scheme of the novel cotton color measuring instrument adopting the LED analog D65 light source, the utility model comprises the following steps: the positive white LED lamp beads and the warm white LED lamp beads are controlled through multichannel light intensity, and the light intensity of the positive white LED lamp beads and the light intensity of the warm white LED lamp beads are independently controlled by adopting a PWM technology.
Compared with the prior art:
The utility model solves the defects of long preheating time, large heating value, large volume and relatively short service life of a halogen tungsten lamp synthetic light source in the traditional color instrument, and simultaneously solves the problems that the existing LEDs are mostly monochromatic light and the existing white light LEDs have great difference with natural light.
