Light emitting device and lighting fixture provided with the same |
| abstract |
Provided is a light emitting device, comprising: a light emitting element including a light emission peak wavelength in a range of 440 nm or more and 470 nm or less; a first fluorescent material having a light emission peak wavelength in a range of 480 nm or more and 518 nm or less; a second fluorescent material having a light emission peak wavelength in a range of 510 nm or more and less than 590 nm and having an x value of the chromaticity coordinate in CIE1931 in a range of 0.27 or more and 0.40 or less; and a third fluorescent material having a light emission peak wavelength in a range of 590 nm or more and 670 nm or less. The light emitting device is capable of reducing the human eye fatigue and having a light emission spectrum with excellent visual work. |
