White light emitting device and LED lighting device |
| abstract |
PROBLEM TO BE SOLVED: To provide a white light emitting device for human-centered lighting and an LED lighting device including the white light emitting device. SOLUTION: The white light emitting device of the present invention has a blue light emitting diode that emits blue light having a peak wavelength in the range of 440 nm to 455 nm, and a peak wavelength in the range of 535 nm to 550 nm and 60 nm or less excited by the blue light. White light emission having a first wavelength conversion material that emits first light having a half-price width and a second wavelength conversion material that is excited by blue light and emits second light having a peak wavelength in the range of 620 nm to 660 nm. The device has a melanopic focal ratio of white light emitted from a white light emitting device of 0.65 or less, and a color play index (CRI) of white light of 80 or more.
