Claim:
1. A light-emitting module comprising: a substrate board; and at least one ultraviolet ray emitter and at least one blue light emitter disposed on the substrate board, the light wavelength of the ultraviolet ray emitter ranging from 380 nm to 420 nm, the light wavelength of the blue light emitter ranging from 440 nm to 470 nm, a wavelength conversion layer being arranged in the light path of the ultraviolet ray emitter and the blue light emitter, the wavelength conversion layer having a first wavelength conversion material and a second wavelength conversion material, the first wavelength conversion material including at least one UV fluorescent material, the second wavelength conversion material including at least one fluorescent material, the first wavelength conversion material receiving the light emitted from the ultraviolet ray emitter and converting the light into a colored light with color temperature ranging from 2000K to 18000K, the second wavelength conversion material receiving and energizing the light emitted from the blue light emitter and converting the light into a colored light with color temperature ranging from 2000K to 18000K, after the lights are mixed, a white light general output optical spectrum being achieved.
