ABSTRACT:
An projector type lamp includes a casing formed with a front open end and configured by connecting an upper casing member and a lower casing member to each other; a concave mirror formed on an inside face of the casing; a light source provided at the first focal point of the concave mirror; a convex lens configured to be held between the upper casing member and the lower casing member at the front open end of the casing and adapted to refract a reflected light that is emitted from the light source and reflected on the concave mirror so as to project a substantially parallel pencil beam forward from the project type lamp; provisional fixers provided on the upper casing member and the lower casing member respectively and configured to latch one another so as to provisionally fix the casing members to one another in place; and a fastener configured to fasten the provisionally-fixed casing members together.
