Title: LIGHT-EMITTING MODULE
Abstract:
A light-emitting module provides desirable white light color rendering so as to achieve a white light display effect expected in various application scenarios. The light-emitting module comprises a substrate (10), and at least one ultraviolet light emitter (20) and at least one blue light emitter (30) that are arranged on the substrate (10). The light wavelength of the ultraviolet light emitter (20) is 380 nm to 420 nm, and the light wavelength of the blue light emitter (30) is 440 nm to 470 nm. A wavelength conversion layer (40) is arranged, and the wavelength conversion layer (40) comprises a first wavelength conversion material (41) and a second wavelength conversion material (42) that are used for receiving light emitted by the ultraviolet light emitter (20) and the blue light emitter (30), exciting the light of the ultraviolet light emitter (20) to generate visible light and converting the light of the blue light emitter (30) into white light, so that a pure white total output spectrum is obtained after light mixing.
