Curved-surface apparatus for wavelength conversing

A curved-surface apparatus for wavelength conversing, comprising:

• a light source excitation unit comprising a blue light source exciters for emitting blue light;
• a wavelength conversion unit provided with annular structure;
• a component set disposed on curved-surface of the annular structure and comprising a first component region having red wavelength conversion substances, a second component region having green wavelength conversion substances and a third component region configured to reflect all color light;
• a beam splitter set configured to reflect red light and green light and transmit blue light;
• a second condenser lens set and a third condenser lens set which is disposed near the wavelength conversion unit;
• a first reflector configured to reflecting all colored light;
• wherein a red light or blue light is generated respectively, when the blue light emitted by the blue light source exciter obliquely penetrates the first component region or the second component region of the wavelength conversion unit, passes the second condenser set and is reflected at the second beam splitter set to project;
• the blue light is reflected when the blue light emitted by the blue light source exciter obliquely penetrates the third component region, passes the third condenser set, is reflected to the beam splitter set by the first reflector and project through the beam splitter set.
