Abstract:
1. A method for generating a high brightness monochromatic light based on wavelength conversion, comprising: A. providing a first wavelength conversion material and a second wavelength conversion material; B. using an excitation light to excite the first wavelength conversion material and the second wavelength conversion material, wherein the first wavelength conversion material absorbs the exciting light and emits a first converted light, the second wavelength conversion material absorbs a first spectral part of the first converted light and emits a second converted light, wherein a light power of the first spectral part absorbed by the second wavelength conversion material is equal to or greater than 50% of a total light power of the first converted light; C. mixing the second converted light and a remaining part of the first converted light which is not absorbed by the second wavelength conversion material to form the high brightness monochromatic light.
