A light emitting module has better white light color rendering index to provide a white rendering effect in accordance with the requirements of various application sites. The light emitting module includes a (circuit) board, and at least one ultraviolet emitter and at least one blue light emitter disposed on the board. The light wavelength of the ultraviolet emitter ranges from 380nm to 420nm. The light wavelength of the blue light emitter ranges from 440nm to 470nm. A wavelength conversion layer is arranged on the board. The wavelength conversion layer includes a first wavelength conversion material and a second wavelength conversion material. The first wavelength conversion material receives and converts the light emitted from the ultraviolet emitter into visible rays and the second wavelength conversion material receives and converts the light emitted from the blue light emitter into white light. After the light is mixed, an average output optical spectrum of the white light is achieved. |
