Abstract
A portable illumination device for reading material in dark or underlit environments. This illumination device is operable upon the opening of its book-like folded covers and upon the tilting of the device to a pre-set angle or greater to close a circuit containing a mercury tilt switch, battery and sources of illumination. Once the device is properly positioned, the plurality of individual illumination sources are activated to illuminate the reading material placed therein. A reading bar incorporating a magnifying glass can be slid along the reading material so as to magnify or highlight such material for easier reading thereof. The tilt switch and battery power sources are preferably located along the spine of the device.
Claims20
A portable illumination device for the illumination of reading material placed thereon comprising:
- (a) a reading material holder having oppositely positioned covers that are connected and foldable together along a common spine region;
- (b) a sheet assembly affixed to each of said covers, said sheet assembly comprising at least one sheet of flat transparent material;
- (c) a plurality of illumination sources secured around a perimeter of each of said sheet assemblies, said illumination sources coupled via circuitry to a power source mounted in said common spine region;
- (d) a first switch provided in said circuitry that is activated to close said circuitry whenever said reading material holder is tilted to a pre-set angle or greater angle;
- (e) a second switch in said circuitry that is activated to open said circuitry whenever said covers are folded together;
- and,
- (f) means secured to said sheet assembly for securing said reading material to said flat transparent material.
A method of portably illuminating reading material comprising the steps of:
- (a) constructing and arranging a reading material holder having oppositely positioned covers that are foldable together along a common spine region;
- (b) affixing a sheet assembly to each said cover, said sheet assembly comprising at least one sheet of flat transparent material;
- (c) securing a plurality of illumination sources around a perimeter of each said sheet assembly, said illumination sources coupled via circuitry to a power source mounted in said common spine region;
- (d) activating a tilt switch in said circuitry to close said circuitry whenever said reading material holder is tilted to a pre-set angle or greater;
- (e) activating a cut-off switch in said circuitry to open said circuitry whenever said covers are folded together;
- and,
- (f) securing said reading material to said flat transparent material.
