Title: Colored light mixing device

Abstract: A colored light mixing device, disclosed having at least one light source set and a color mixing plate. The light source set has three light generating units which generate light of different colors. The color mixing plate is made of transparent material, having a lower surface that faces the at least one light source set with a lower wavelike pattern and an upper surface opposite thereto with an upper wavelike pattern that is oriented differently from the lower wavelike pattern. Being hit by light from the at least one light source set, the lower wavelike pattern acts as a plurality of linear light sources for light of mixed colors inside the color mixing plate being illuminated by light from the lower wavelike pattern, the upper wavelike pattern emits light of uniform intensity and mixed hue.
