A multi-wavelength white light-emitting structure uses a UV light emitting diode chip and a blue light emitting diode chip to excite a red phosphor and a green phosphor and generates a white light-emitting structure having good color rendering. The multi-wavelength white light-emitting structure uses a UV light emitting diode chip that emits light having a wavelength of between 350˜430 nm to excite a red phosphor to emit red light having a wavelength of between 600˜700 nm. The present invention then uses a blue light emitting diode chip that emits light having a wavelength between of 400˜500 nm to emit blue light and uses the blue light emitting diode chip to excite a green phosphor to emit green light having a wavelength of between 490˜560 nm. Mixing the red light, the blue light and the green light forms a white light.
