LIGHT SOURCE DEVICE |
| 摘要 |
A light source device having; a blue light emitting element that emits blue light having an emission peak in a wavelength region of 440 nm to 460 nm; a green phosphor that absorbs part of the blue light emitted by the blue light emitting element and thereby emits green light having an emission peak in a wavelength region of 500 nm to 575 nm; a red phosphor that absorbs at least one of part of the blue light emitted by the blue light emitting element and part of the green light emitted by the green phosphor, and thereby emits red light having an emission peak in a wavelength region of 600 nm to 690 nm; and an absorbent containing neodymium fluoride that absorbs part of the green light and part of the red light. |
