An illumination system for stage lighting and a method for providing high-brightness white light are provided. The illumination system for stage lighting includes LED arrays (1, 2, 3) which are packaged on a heat dissipation plate and consist of several LED chips, an optical combination device (4) which can combine the light emitted by respective LED chips to one beam, a focusing lens (5) which can focus the light emitted by the optical combination device to a light-emitting window (11), a transmissive type wavelength converter (7) and a control processing device. When white light is provided, the control processing device controls the LED chips with predetermined wavelengths to emit light and the transmissive type wavelength converter is cut into the light path to generate excited light. |
