IPC: F21V29/00
Filed: 2001-10-04
Abstract: PROBLEM TO BE SOLVED: To compose a shading reflection type device having high outward radiation efficiency, a large contrast between a lighting time and a lighting-out time and an excellent heat radiation property. SOLUTION: In a shading reflection type LED 1, nearly entire flux emitted from a light source 10 reaches an elliptic surface of revolution of a reflecting mirror 6 formed by rotating a part of an ellipse focusing on the light source 10 and optical opening parts 2, and reflected light is emitted to the outside from the nearly circular opening parts 2 with high efficiency. Since black silk printing is applied to the surface of a board part 7 with the light source 10 fixed, external light entered from the opening parts 2 in the lighting-out time is reflected by the reflecting mirror 6 and absorbed on the surface of the board part 7, so that pseudo lighting by re-emission of the external light from the opening parts 2 can completely be prevented and the contrast between the lighting time and the lighting-out time can be increased.  The heat of the light source 10 is transmitted to metal powder filled in through-holes of a board 11 and solder filled in the through-holes of the board part 7 and efficiently radiated.
