般的である。2. Description of the Related Art A lamp unit conventionally used in a projection image device using a liquid crystal panel is shown in FIG. 4 and will be described. Conventionally, this type of lamp unit is made of a lamp 1, a reflecting surface 2 having a curved shape, a wire rod 3 required to supply electric power to the lamp 3, a metal fitting 4, screws 5, and a metal plate for surrounding and protecting them. A case 6, a reflecting mirror 2 having a curved shape, a fixing metal fitting 7 for fixing the case 6 made of sheet metal, and a connector 8 for receiving externally electric power necessary for lighting the lamp are provided. It is common.

【発明が解決しようとする課題】このランプユニットは
反射鏡２が曲面形状をなすため全体的に比較的に大きな
箱型形状をなしており、また、多くの部品からなるため
コスト的にも大きなものとなっている。This lamp unit has a relatively large box shape as a whole because the reflecting mirror 2 has a curved surface shape, and also has a large cost because it is composed of many parts. It has become a thing.
【０００４】したがって、この種のランプユニットを構
成する部品の点数を最小限に抑え、廃棄される部分を少
なくすることで低コストとし、且つ小型であることが望
ましい。Therefore, it is desirable that the number of parts constituting this type of lamp unit is minimized and the amount of discarded parts is reduced to reduce the cost and the size.
【０００５】[0005]
【課題を解決するための手段】本発明によれば反射鏡の
曲面を階段状の反射面とし、小型化を計り、これに付属
する部品の点数も減らしたランプユニットが得られる。According to the present invention, it is possible to obtain a lamp unit in which the curved surface of the reflecting mirror is a stepwise reflecting surface, the size of which is reduced, and the number of parts attached thereto is reduced.
