Abstract:
An illumination lens condenses a light from a light source and emits the light toward a display to illuminate the display. The illumination lens includes multiple first lens surface parts having a shape obtained by extracting multiple portions of a first virtual lens surface along a first optical axis, the first virtual lens surface defining the first optical axis on which the light source is disposed and being at least twice differentiable between optical axes arranged in a reference direction, and multiple second lens surface parts having a shape obtained by extracting multiple portions of a second virtual lens surface along a second optical axis, the second virtual lens surface defining the second optical axis and being at least once differentiable between the optical axes arranged in the reference direction. The first lens surface parts and the second lens surface parts are alternately arranged in the reference direction.

Claim (Index 16):
A head-up display device that projects an image onto a display member of a moving object to visibly display a virtual image of the image from an interior of the moving object, the head-up display device comprising:\n a display that displays the image; a light source that emits a light; and an illumination lens that condenses the light from the light source and emits the light toward the display to illuminate the display, wherein the illumination lens includes: a plurality of first lens surface parts formed into shapes obtained by extracting respective parts from each first virtual lens surface that is a virtual lens surface defining a first optical axis, the light source being located on the first optical axis, the first virtual lens surface being twice differentiable; and a plurality of second lens surface parts formed into shapes obtained by extracting respective parts from each second virtual lens surface that is a virtual lens surface defining a second optical axis, the second optical axis being deviated in a reference direction from the first optical axis, the second virtual lens surface being at least once differentiable, the plurality of second lens surface parts is arranged alternately with the plurality of first lens surface parts in the reference direction, wherein an arrangement where the plurality of first lens surface parts and the plurality of second lens surface parts are arranged alternately one by one in the reference direction is defined as an alternating array structure, the alternating array structure is one of a plurality of alternating array structures, and the plurality of alternating array structures are axisymmetric with respect to the second optical axis.
