Abstract

A lighting unit includes a light source configured to radiate a light, a circuit board on which the light source is mounted, and multiple stages of condenser lenses configured to condense the radiation light radiated from the light source. A first-stage lens that is located closest to the light source and given a maximum positive power among the multiple stages of condenser lenses has a partition wall portion and a positioning portion. The partition wall portion partitions an accommodation space in which the light source is accommodated in a range from a composite focal point of the multiple stages of condenser lenses to the first-stage lens by projection toward the circuit board side. The positioning portionis provided on the partition wall portion and positioned relative to the circuit board by concavo-convex fitting.
