LIGHT-EMITTING-TYPE BRAILLE BRICK SYSTEM FOR A SIDEWALK
Document Type and Number:
WIPO Patent Application WO/2010/137842
Kind Code:
A2
Abstract:
The present invention relates to Braille brick for a sidewalk, which is installed along a guiding path to the crosswalk on a sidewalk, a subway standby line or the like to provide a visually impaired person with protruding patterns, and to a low-power-consuming light-emitting-type Braille brick system for a sidewalk, which has a predetermined light-emitting function operating in conjunction with an external signal which serves as a signal for operating an external system such as traffic lights and subway information displays, thereby providing more correct information and exhibiting significantly improved discriminating ability. In detail, the present invention provides a light-emitting-type Braille brick system for a sidewalk, comprising: a coupling unit which is physically coupled to a cable of an external system to which a predetermined driving signal is applied, and which generates a synchronizing signal coupled with the driving signal; a Braille sidewalk brick which has a light source for emitting light embedded therein, and which has one surface along which protruding patterns made of materials through which light can penetrate for the penetration of the light emitted by the light source, wherein said Braille sidewalk brick is installed on the sidewalk such that said one surface thereof is exposed outward; and a control unit which has a battery embedded therein, and which is electrically connected to the light source to selectively apply electrical energy charged in the battery to the light source in accordance with said coupled signal.
