Abstract:
An illumination device is provided with a light source device including a first light-emitting element that emits a first pencil of rays, and a light shaping optical system including a first lens surface on which the first pencil of rays is incident. The first lens surface has a first free-form surface represented by Expression (1) in which x and y are used as variables. In Expression (1), in a case where h is set to a positive integer, the coefficient C j  of the x 2h  term is different from the coefficient C j  of the y 2h  term. z = cr 2 1 + 1 - ( 1 + k )  c 2  r 2  + ∑ j = 2 s  c j  x m  y n ( 1 )

Claim (Index 19):
A projector comprising:\n the illumination device according to  claim 16 ; a light modulating device that modulates illumination light from the illumination device in accordance with image information and generates image light; and a projection optical system that projects the image light, wherein the light source device further includes a third light-emitting element that emits a third pencil of rays, the light shaping optical system further includes a third lens surface on which the third pencil of rays is incident, the third lens surface has a third free-form surface which is represented by Expression (1), the coefficient C j  of the x 2h  term is different from the coefficient C j  of the y 2h  term, with respect to the third free-form surface, the light shaping optical system is configured to illuminate an entirety of the region to be illuminated with the third pencil of rays, the light source control device is configured to control an output of the third light-emitting element independently of at least one of an output of the first light-emitting element and an output of the second light-emitting element, and an image forming region of the light modulating device is equivalent to the region to be illuminated.
