Abstract :

The color temperature of light is one of the important indicators in lighting that should be considered. Because people experience and feel their surroundings not only with brightness and darkness, light and shadow but also through colors, the feeling that the color of the light creates in the space affects human perception and health through the warmth and coldness of the light. The color receptivity and color temperature chart is a tool that determines how the human eye feels when faced with a spectrum of light. Since the purpose of this research is to analyze the light quality of the s‌tained glass windows of traditional Iranian architecture, calculating the color temperature will be a suitable criterion for judgment, that is, if the color temperature of the light from the s‌tained glass windows is calculated, the experience of people in facing the light can be calculated quantitatively. Comparative methods were used to analyze the quality of light based on the color temperature curve with calculation tris‌timulus values XYZ from spectral data and calculation xyz chromaticity values. Inves‌tigations showed that the light color temperature of 65% of the windows is 3000 to 4600 K, and 35% is. In these windows with this combination model and area percentage of four colors, red, green, blue, and yellow, the quality of light has not decreased based on the color temperature curve.
