Abstract

A computer program to calculate the color temperature (To) and color rendering index (Ra) of the light source was developed. Using this program and a measuring system with a monochromator and a integrating sphere, To and Ra of incandescent lamp and fluorescent lamp was calculated. As a result, it is known that To of the I/L and the F/L with a reactor ballast is changing about 40˚K with varying source voltage of 5 V. Ra variations of these lamps have a trend but can be disregarded.
