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 2):
The illumination device according to  claim 1 , wherein Expression (1) includes at least one of a first-order term of x and a first-order term of y, and\n the Expression includes at least one x p y q  term, in a case where p and q are set to positive integers.
