An Algorithm for Improving Light Source Color Rendering Index to Approach Natural Spectrum

Abstract

The invention relates to an algorithm for improving the color rendering index of a light source to approach the natural spectrum. In order to adjust and obtain the set brightness, chromaticity, and color temperature, it is necessary to change the current of the red light, green light, and white light. Due to the adjustment of the current, the color of a single light source The brightness value and color temperature value have little influence, so only the influence on the brightness is considered. The brightness adjustment algorithm: the ratio of the current brightness: use the trial and error method to adjust the current size, use the spectrometer to collect the brightness value, and compare the brightness value obtained after adjusting the current. If it is equal to the brightness value calculated by the algorithm, if not, continue to adjust the current value and repeat the process of comparing the brightness value collected by the spectrometer, successively approximating so that the adjusted brightness of the final current gain is consistent with the theoretically adjusted brightness value.

Description

Technical field [0001] The present invention relates to the field of lamp technology, and more particularly to an algorithm for increasing the light source color color index approximation of natural spectroscopy. Background technique [0002] In recent years, with the continuous development of LED technology, the LED is possible as a lighting source, but the light source has a strict requirement of the color color index in lighting fixtures. Unfortunately, the LED lighting market is still in a more confusing state, and each color color index is uneven. In addition, LEDs have also been confirmed that LED blue light will threaten fundamental health, and it is easy to induce relevant ophthalmic diseases, and become the restriction problem of LED lighting products. [0003] The color change index refers to the degree of reducing the color of the nature when the object is illuminated with a certain light source and performs a standard light source (typically a standard light source in...

Problems solved by technology

[0006] ⑴Currently, the cost of the existing scheme is relatively high by adjusting the coating material

[0007] (2) And through the adjustment of the coating material, it is easily affected by the temperature during use

[0008] (3) Some increase R by adding red powder 9 Equal color rendering index, higher cost

[0009] ⑷The scheme of adding red, green and blue lamp beads cannot effectively reduce the interference of blue light, and at the same time cannot arbitrarily adjust the brightness and chromaticity of the light to achieve the effect of improving the color rendering index
