ABSTRACT:
An illumination device has a blue light emitting element that emits blue light and a light guide member that guides blue light emitted from the blue light emitting element to a light exit surface of the light guide member. A first color conversion element includes a red phosphor that emits red light in response to excitation with the blue light. The first color conversion element is disposed on an optical path between the blue light emitting element and the light guide member. A second color conversion element is disposed on a light exit surface side of the light guide member and separated from the first color conversion element. The second color conversion element comprises a pair of non-permeable transparent substrates, a resin disposed between the non-permeable transparent substrates, and a green phosphor dispersed in the resin for emitting green light in response to excitation with the blue light.
