Abstract

The disclosure relates to a method for adjusting the color temperature of a light source in a dimmable light fixture, wherein the light source need not be customized. The method comprises at least two groups of LED lamp beads with different color temperatures are adopted as the light source of a dimmable light fixture. The color temperature of the light source may be kept unchanged at any one of the color temperature values between the maximum and minimum color temperature values of the light source or the color temperature value of the light source may vary between any two of the color temperature values between the maximum and minimum color temperature values of the light source, and the brightness is getting darker and the color temperature is getting lower. The adjustment method of the present disclosure can be widely applied to various dimmable light fixtures.
