Light-emitting module |
摘要 |
A light-emitting module has better white light color rendering index to provide white rendering effect in accordance with the requirements of various application sites. The light-emitting module includes a (circuit) 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 ranges from 380 nm to 420 nm. The light wavelength of the blue light emitter ranges from 440 nm to 470 nm. A wavelength conversion layer is laid on the substrate board. The wavelength conversion layer includes a first wavelength conversion material and a second wavelength conversion material for receiving and converting the light emitted from the ultraviolet ray emitter into visible light and the light emitted from the blue light emitter into white light. After the lights are mixed, a white general output optical spectrum is achieved. |
