Title: Optical device with variable directivity
Inventor: HARADA YOSHIO
IPC: H01L31/10
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To vary the radiation range of light beams, by disposing a concave reflection mirror to cover with it the outer periphery of a lens package having enclosed light-emitting and-receiving elements therein. SOLUTION: Forming a cylindrical member 15 with a conic inner peripheral surface 15a spreading gradually from its nearly central portion toward its front end, a light reflecting material is applied to the surface 15a to provide a concave reflection mirror 16. When a lens package 14 is placed most backward, since most of light beams 18 are reflected projectively by the concave reflection mirror 16, the radiation range of the light beams 18 becomes narrowest to make the directivity of an optical device largest. When a lever 17 is pressed forward to advance the lens package 14 in the cylindrical member 15, accordingly to this, the projectively reflected light quantity of the outer peripheral portion of the light beams 18 by the concave reflection mirror 16 is reduced to make the radiation range of the light beams 18 wide.  When a convex lens 14a is moved most forward, eliminating the reflection of the light beams 18 by the concave reflection mirror 16, their radiation range becomes widest to make the directivity of the optical device smallest. In this way, the radiation range of the light beams 18 can be varied.
