Abstract
A light source, comprising: an excitation light source and a wavelength conversion apparatus. The excitation light source comprises a housing, a laser chip, and a light beam guiding element. The housing forms a packaging cavity. The packaging cavity is provided with a light outlet. The wavelength conversion apparatus is spaced apart from the housing and corresponds to the light outlet. The wavelength conversion apparatus and the excitation light source are separately arranged, and the housing of the excitation light source and the wavelength conversion apparatus are spaced apart, so that the wavelength conversion apparatus can be easily maintained and replaced, so as to avoid waste by discarding the entire light source.
