A bi-directional excitation color wheel includes a first working surface and a second working surface which are of the same size, wherein the first working surface includes a first working ring and a second working ring which are concentric rings; the second working surface includes a third working ring and a fourth working ring which are concentric rings; the first working ring includes a first translucent region and a green fluorescent region, the second working ring includes a second translucent region, the third working ring includes a third translucent region, and the fourth working ring includes a fourth translucent region and a first fluorescent region; the first translucent region and the third translucent region are the same translucent region, and the second translucent region and the fourth translucent region are the same translucent region.

Bi-directional excitation color wheel and light source system thereof

A curved-surface apparatus for wavelength converting. The apparatus includes: a light source excitation unit comprising a plurality of light source exciters for emitting identical or different excited light, respectively; a wavelength conversion unit provided with annular structure; a plurality of component sets circularly disposed on a curved surface of the annular structure and divided into a plurality of component regions provided with predetermined color wavelength conversion substances; a beam splitter set configured to reflect the excited light emitted by the light source excitation unit and transmit predetermined light; a condenser lens set disposed near the wavelength conversion unit.

Curved-surface apparatus for wavelength converting

A color wheel includes an inner ring, including translucent regions which are diagonally distributed; and an outer ring, including fluorescent regions and a translucent region, the fluorescent regions including green fluorescent regions and yellow fluorescent regions, the green fluorescent regions being diagonally distributed; wherein, the angles of the translucent regions of the inner ring are greater than or equal to the angles of the green fluorescent regions of the outer 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 inner 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.
