Abstract:
Illumination device ( 100 ) includes light source ( 110 ), lens ( 120 ) including first region ( 120 a ) having negative power and second region ( 120 b ) having positive power, and drive ( 130 ) that changes a relative distance between light source ( 110 ) and lens ( 120 ). The light of light source ( 110 ) passes through first region ( 120 a ) and second region ( 120 b ) even when the distance is changed to any distance by drive ( 130 ).

Claim (Index 19):
An illumination device comprising:\n a plurality of light sources including a first light source and a second light source that emit light; a plurality of illumination optical systems including a first optical system and a second optical system that output the light emitted from the plurality of light sources, by changing a travel direction, concentration, or divergence of the light; and a zoom mechanism unit that changes relative distances between the plurality of light sources and the plurality of illumination optical systems, wherein assuming that when the illumination device is set to a wide angle end, a position of the first light source, a position of the second light source, a position corresponding to center of the first optical system, and a position corresponding to center of the second optical system are represented by position WL 1 , position WL 2 , position C 1 , and position C 2 , respectively, that when the zoom mechanism unit of the illumination device is set to a telephoto end, a position of the first light source, a position of the second light source, a position corresponding to center of the first optical system, and a position corresponding to center of the second optical system are represented by position TL 1 , position TL 2 , position TC 1 , and position TC 2 , respectively, that a virtual axis linking position WL 1  and position C 1  is represented by axis AW 1 , that a virtual axis linking position WL 2  and position C 2  is represented by axis AW 2 , that a virtual axis linking position TL 1  and position TC 1  is represented by axis AT 1 , that a virtual axis linking position TL 2  and position TC 2  is represented by axis AT 2 , that an angle defined by axis AW 1  and axis AW 2  is represented by \u03b8W, and that an angle defined by axis AT 1  and axis AT 2  is represented by \u03b8T, a relationship of \u03b8W>\u03b8T is satisfied.
