DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
Compact computer apparatuses having video viewing screens are quite popular and typically comprise hand-held, portable, battery-operated devices which typically display information or play games employing a video screen, particularly a generally flat, liquid crystal display (LCD) screen. Such compact video computer apparatuses may include, but not be limited to: calculators, computer video games, lap top computers and other computers where a variety of software is employed. In particular, compact video games, such as the compact video game system known as GAME BOY.TM. (a trademark of Nintendo of America, Inc.), is a completely self-sustained video game system which may be operated by employing a collection from a library of software game packs. The Nintendo GAME BOY.TM. compact video game system provides a compact, self-contained, battery-operated, portable, hand-held computer with a cross key joy stick to operate the game and start and select buttons with an LCD-type screen, together with volume controls so as to display and enable the user to display images and play games.
While video display screens are employed and typically include a flat LCD-type screen, such LCD-type display screens are often difficult to observe by the user in partial light, particularly, for example, in semi-darkened rooms, automobiles, planes, trains, buses and the like due to the lack of illumination on the LCD screen to permit suitable contrast during use.
Therefore, it is desirable to provide a light apparatus to enhance the view of the video screens of compact video systems, particularly video systems employing a flat, LCD-type screen, such as for example, as illustrated by the Nintendo GAME BOY.TM. video game system.
SUMMARY OF THE INVENTION
The present invention relates to a light apparatus used with a compact computer video screen. More particularly, the invention concerns a portable, battery-operated, hand-held light apparatus for use with a portable, battery-operated, hand-held computer video screen system employing an LCD screen to enhance the user's viewer of the LCD screen.
The invention comprises a light apparatus particularly a portable, hand-held, battery-operated light apparatus for use in combination with a computer apparatus having a video screen, such as compact video game system, in order to enhance the display of the video screen. The light apparatus generally comprises a body section, such as a molded plastic top and bottom section, having a plurality of, for example generally four, spaced apart, generally perpendicular to the screen light-colored panels which define an open viewing area in the body, the open viewing area adapted to match, i.e. generally rectangular, the viewing area of the video screen of the compact video apparatus with which the light apparatus is to be employed. The side panels extend outwardly about the sides of the open viewing space and generally are perpendicular outwardly from the compact video game screen to be enhanced, and generally are white or a light color to reflect indirect lighting. The light apparatus includes a battery section for the placement of batteries as a power source and includes electrical wires extending from the battery and electrically connected to an off/on switch and hence to a pair of small light bulbs placed on either side of the side panels, the lights adapted to be powered by the batteries and operated by the off/on switch. The lights are placed on opposing sides of the panel section and while in operation provide indirect enhancement light which is reflected from the side panels onto the viewing screen of the video screen of the compact computer apparatus in use thereby enhancing viewing of the LCD screen.
In addition, the light apparatus includes means by which the body section, including the battery section, may be clipped directly on in a snap-on fashion or otherwise retained in and on the compact computer so that the open viewing space of the body section of the light apparatus may fit directly over the video screen w
