INNER LENS AND VEHICLE LAMP INCLUDING SAME

WIPO Patent Application WO/2021/106951

A1

The present invention increases the degree of freedom regarding the shape of an inner lens while suppressing or avoiding any effect to optical characteristics of the inner lens.　This inner lens includes: a first light emission surface (43) that extends along a first direction (D1); and a first light reflection surface (47) in which a plurality of first prisms (47j) are arrayed along the first direction (D1). The inner lens further includes: a second light emission surface (44) that is provided adjacently to a distal part of the first light emission surface (43) in the propagation direction of propagating light; and a second light reflection surface (48) that is disposed so as to at least partially oppose the second light emission surface (44). The second light emission surface (44) is provided inclined with respect to the first light emission surface (43) so as to transmit a portion of the propagating light that is propagating in the first direction (D1). The second light reflection surface (48) is provided with a plurality of second prisms (48j) for re-reflecting, toward the second light emission surface (44), at least a portion of the propagating light reflected by the second light emission surface (44).
