ABSTRACT:
BACKGROUND OF THE INVENTION
The use of portable lighting devices is known in the prior art. For instance, there have been a number of patents issued for lights adapted to be used inside of a women's purse. These include U.S. Pat. Nos. 5,424,926; 4,774,638 and 5,934,790. There are also patents for portable lights including U.S. Pat. No. 5,347,440, as well as patents utilizing fluorescent lighting such as U.S. Pat. Nos. 4,268,894 and 4,432,043.
The purse lights are not adequate for the job for which they are intended because they all use a small light bulb which simply does not provide enough light and the light is focused in one small spot where the bulb is located. The fluorescent lighting devices cannot be used for personal or purse use because they are all too large to fit in one's pocket or purse.
SUMMARY OF THE INVENTION
Applicant's invention comprises a small, portable, hand-held, battery-operated light which provides the broad lighting of a fluorescent light, but is considerably brighter, yet has the small size previously only attainable with a light bulb. Applicant's lighting device is adapted to stand on its own, on a flat surface, so that it does not have to be held, freeing the user's hands. It may be hung on a hook or hung around the user's neck, with a neck strap, or it may be removeably attached inside of a purse, briefcase or other container. It is small enough that it may be carried in a pocket and taken to places it is needed such as a dark restaurant or work area.
Applicant accomplishes these results by the use of a fluorescent cold cathode lamp which provides a remarkable amount of light for its size, allowing the device to be made quite small and yet provide very effective lighting. In addition, it may use rechargable batteries so that periodic battery replacemant is unnecessary.
OBJECTS OF THE INVENTION
Accordingly, several objects and advantages of the invention are as follows:
It is an object of the present invention to provide a small, portable lighting device which provides considerable light and yet is small in size.
Another object of the invention is to provide such a device which may stand on a flat surface so that the user's hands are free.
Yet another object of the invention is to provide such a device which may be removeably attached in a purse, briefcase or other container.
