Abstract:
A light-emitting device includes blue LED chips having a light emission peak wavelength of at least 430 nm and at most 470 nm and red LED chips having a light emission peak wavelength of at least 600 nm and at most 640 nm. The light-emitting device includes a yellow phosphor having a light emission peak wavelength of at least 500 nm and at most 580 nm and a red phosphor having a light emission peak wavelength of at least 640 nm and at most 670 nm. The light-emitting device emits white light through mixing of light emitted by each of the blue LED chips, the red LED chips, the yellow phosphor, and the red phosphor.
