Lighting apparatus facilitating reading
The invention relates to a lighting device (LIGHT) of a graphic and/or textual content represented on any support and in particular of the paper type, characterized in that a light beam generated in a visible light spectrum is activated and periodically deactivated from the lighting device (LIGHT) according to successive cycles operated at a predetermined frequency (Fd) and in that the successive illumination periods each have a duration (T 1 ) within a range of values from 15 to 30% of the duration (T) of the operated cycles.
1. A lighting device for facilitating the reading of graphical and/or textual content printed on a medium for persons prone to dyslexia, the lighting device comprising:
a control unit; and
a lighting module configured to provide illumination in a visible light spectrum, of the graphical and/or textual content printed on the medium, said control unit and said lighting module being configured to:
periodically activate and deactivate said illumination in successive cycles operated at a predetermined frequency between 60 Hz and 90 Hz, said predetermined frequency being a reciprocal of a sum of a period of activation of said illumination and a period of non-activation of said illumination; and
operate successive illumination periods each having a duration in a range of 15 to 30% of said successive cycles.
2. The lighting device according to claim 1 , wherein said illumination is generated from one or more LED-type elements.
3. The lighting device according to claim 1 , wherein said device is one selected from a group consisting of: a desk lamp, a flashlight, a headlamp, a pen-lamp, a flashlight, a telephone lamp, a smartphone lamp, a lamp-watch, a key-door lamp, a ceiling lamp, a lamp-post, a bulb, a lighting tube, a projector, an automobile projector, an overhead projector, a luminous wall covering, a light carpet, a luminous bracelet, a light frame, a mini-lamp to be positioned on a book, a device configured for interior lighting and a device configured for outdoor lighting, urban or otherwise.
4. A lighting device for facilitating the reading of graphical and/or textual content printed on paper for persons prone to dyslexia, the lighting device comprising:
a control unit; and
a lighting module configured to provide illumination in a visible light spectrum, of the paper and graphical and/or textual content printed thereon, said control unit and said lighting module being configured to:
periodically activate and deactivate said illumination in successive cycles operated at a predetermined frequency between 60 Hz and 90 Hz, said predetermined frequency being a reciprocal of a sum of a period of activation of said illumination and a period of non-activation of said illumination; and
operate successive illumination periods each having a duration in a range of 15 to 30% of said successive cycles.
5. The lighting device according to claim 4 , wherein said illumination is generated from one or more LED-type elements.
6. The lighting device according to claim 4 , wherein said device is one selected from a group consisting of: a desk lamp, a flashlight, a headlamp, a pen-lamp, a flashlight, a telephone lamp, a smartphone lamp, a lamp-watch, a key-door lamp, a ceiling lamp, a lamp-post, a bulb, a lighting tube, a projector, an automobile projector, an overhead projector, a luminous wall covering, a light carpet, a luminous bracelet, a light frame, a mini-lamp to be positioned on a book, a device configured for interior lighting and a device configured for outdoor lighting, urban or otherwise.
