Color wheel and laser light source system thereof

A color wheel, comprising:

• an outer ring, comprising translucent regions which are diagonally distributed;
• and
• an inner ring, comprising fluorescent regions and a translucent region, the fluorescent regions comprising green fluorescent regions and yellow fluorescent regions, the green fluorescent regions being diagonally distributed;
• wherein, the angles of the translucent regions of the outer ring are greater than or equal to the angles of the green fluorescent regions of the inner ring, the angle extension lines of the ring-shaped green fluorescent regions passing through the center of a circle fall within the ring-shaped translucent regions of the outer ring, such that the green light generated in the green fluorescent regions passes through the translucent regions after being reflected, and the yellow light generated in the yellow fluorescent regions is projected to a red light filter after being reflected.
