    Abstract: An optical wheel according to the present invention includes a luminescent material light emitting area on which light in a first wavelength range is incident from one side to thereby emit luminescent light excited by the light in the first wavelength range from another side, and a controlling and diffusing optical area including a controlling section on which the light in the first wavelength range is incident from the one side and configured to cause a diffusing characteristic of the light in the first wavelength range to differ between in a radial direction and in a circumferential direction.

    Abstract: According to an embodiment of the invention, there is provided a light source unit including a solid light emitting device which emits light source light, a diffuse plate which diffuses the light source light, and a light guiding device which diffuses light which exits from the diffuse plate, wherein the diffuse plate has a plurality of arc-shaped diffuse cells arranged along either of a first direction of an exit side surface thereof which lies opposite to an entrance side where the light source light enters and a second direction that intersects the first direction at substantially right angles, and wherein a diffuse angle in the first direction differs from a diffuse angle in the second direction.
