发明名称 Lamp unit, projector, and fixing method of light source lamp and reflector
摘要 Since a light source lamp (11) and a reflector (12) of a lamp unit (10) are respectively fixed to a lamp housing (13) in a mutually independent manner, an attachment for attaching and fixing the light source lamp (11) is not necessary to be formed on the reflector (12) as an optical component, so that the shape of the reflector (12) can be simplified and accuracy of a reflection surface (121), especially at a bottom thereof, can be easily improved, thereby enhancing illumination of the lamp unit (10).
