A light emitting module for producing a visible light by passive ultraviolet excitation includes an excitation light source member and at least one layer of wavelength modulation matrix. The excitation light source member produces an ultraviolet light with a specific wavelength range. The wavelength modulation matrix adopts an organic polymer as a carrier, and the carrier adds a composite material composed of an organic wavelength modulation material, a quantum dot luminescence color rendering modulation material and a nanoparticle brightness enhancement luminescence powder, and the composite material is cured and formed by coating, injection molding, thin film lamination, screen printing or thick film printing, so that when the wavelength modulation matrix is projected by an ultraviolet light beam emitted by the excitation light source member, a light including a visible light is produced.
