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 15):
The illumination device according to  claim 1 , wherein the light source device further includes a second light-emitting element that emits a second pencil of rays,\n the light shaping optical system further includes a second lens surface on which the second pencil of rays is incident, the second lens surface has a second 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 second free-form surface, and the light shaping optical system is configured to cause the first pencil of rays and the second pencil of rays to be incident on regions to be illuminated which are different from each other.
