Abstract
An illumination apparatus includes an elongate chassis, a plurality of light emitting devices, a plurality of lenses, an elongate populated board, an elongate holding member, and a heat radiation member. The chassis includes a supporting portion supporting the opposite, longer-side ends of the populated board and a first engagement portion fitting and securing the holding member to the chassis. The holding member includes a plurality of second engagement portions fitting and securing each lens to the holding member and a resilient biasing portion resiliently biasing the longer-side ends of the populated board toward the supporting portion. The populated board is pinched and secured by the resilient biasing portion and the supporting portion and the heat radiation member is sandwiched and thus secured by the populated board and a bottom wall in contact with the populated board and the bottom wall.
