Abstract

PURPOSE: To effectively utilize a light source flux and also to reduce a number of fitting components, by forming a reflecting surface at an inner surface of the fitting proper having a square opening, and by forming a high efficient reflecting surface in the direction ranging to a socket fitting hole of the fitting proper.
CONSTITUTION: An opening of a fitting proper 7 is formed in a square, and a reflecting surface 8 is formed right in an inner surface of the fitting proper 7. The reflecting surface 8 is formed in such manner that forms a high efficiency reflecting surface 10 in the direction C ranging to a socket fitting hole 9 from the square opening 2. That is, the high efficiency reflecting surface 10 is formed in a parabola or a similar line so that the focus shall be placed on a lamp 4. In this case, the high efficiency reflecting surface 10 can also be formed in an oval, according to applications, so that one of two focusses shall be placed on the lamp 4.
