First Claim
Patent Images
1. A glare-shielding type reflector comprising:
- a reflecting block having a mirror for reflecting incident light rays which impinge upon said reflecting block at different angles;
a plurality of glare-shielding layers individually formed on an incident side of said mirror said layers being driven individually;
a driving means for individually driving said plurality of glare-shielding layers by application of an electric field thereto;
a photosensor means for detecting incident angle and intensity of each of said incident rays reflected on said mirror through each of said glare-shielding layers; and
a control means for generating a control signal to allow said driving means to drive at least one of said glare-shielding layers in response to said incident angles of incident rays.

Abstract
This invention discloses a glare-shielding reflector which controls light reflectance electrically. The present invention provides a glare-shielding type reflector having a photosensor block which can detect an incident angle of a luminous flux to the reflector and a glare-shielding layer which is divided into plural units and driven individually. A glare-shielding layer formed on a front surface of a mirror is divided into plural units and only the specified glare-shielding units are automatically put into a glare-shielding state, according to the incident angle of the luminous flux to the mirror.
