Patent Application Titled "Light-Sensing Illumination System" Published Online

September 11, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventor Lemon, Deborah (Carrollton, TX), filed on February 14, 2014, was made available online on August 28, 2014.

No assignee for this patent application has been made.

Reporters obtained the following quote from the background information supplied by the inventors: "The present application relates generally to illumination systems and more particularly, but not by way of limitation, to dark-area-illumination systems ('DAIS') utilizing both a light source and a light sensor coupled thereto. The DAIS may, in one embodiment, be connected to an object, such as keys, which are often disposed inside, for example, a dark purse. In another embodiment, the DAIS may be connected to a lighting system for the dark area, such as, for example, a closet.

"Dark areas requiring illumination are found frequently in the home and in the workplace. Dark areas include closets, attic spaces, basements, crawl spaces, and the like. Other examples of dark areas include containers such as purses, handbags, briefcases, and backpacks, which are very prevalent and useful to both children and adults alike. Frequently, dark areas do not permit infiltration of ambient light thereby reducing ambient illumination of the dark areas, particularly in low-ambient-light conditions. This can present problems when trying to locate objects such as, for example, a set of keys disposed within, for example, a dark purse.

"Illumination systems have been developed and integrated into various articles such as purses, handbags, briefcases, backpacks, and the like to provide illumination when the article is opened. Such illumination systems frequently utilize various types of user-actuated switches to activate a lamp. For example, U.S. Pat. No. 8,147,086 discloses a purse light with a touch-sensitive switch. The purse light includes a light-emitting portion, a power source, and a touch-sensitive switch. U.S. Pat. No. 7,246,915 discloses a receptacle illumination device. The device includes a light-emitting membrane electrically connected to a power supply and a switch. U.S. Pat. No. 6,508,568 discloses a light assembly for an interior of a purse. The light assembly includes an illumination source, a power source, and a switch assembly. U.S. Pat. No. 4,954,934 discloses a purse light having a switch that actuates a battery-powered light when the switch is in an 'on' position. Finally, U.S. Pat. No. 4,934,790 discloses a purse-light system having an illumination lamp that is activated for a pre-determined period of time by closing a momentary-contact switch.

"Switch-actuated illumination systems rely on a user's ability to find and actuate a switch. Such a task may be made considerably more difficult in low-ambient-light environments such as a darkened closet or a darkened movie theater."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "The present application relates generally to illumination systems and more particularly, but not by way of limitation to a DAIS utilizing a light sensor. In one aspect, the DAIS is adapted for coupling to keys or the like to facilitate the location thereof. The DAIS includes a power source, a light source electrically coupled to the power source, and a light sensor electrically coupled to the power source and the light source. The light sensor activates the light source responsive to a pre-determined minimum-lumen threshold being reached. The DAIS is coupled to an object, such as keys and placed inside an interior of a dark area to facilitate finding said keys.

"In another aspect, the present invention relates to a method for providing illumination to an interior of a dark area, such as a closet. The method includes placing a DAIS into an interior of a dark area and connecting the DAIS to either an independent light source and/or an electrical system servicing the dark area. The method further includes determining if a pre-determined minimum-lumen threshold has been reached. Responsive to the pre-determined minimum-lumen threshold being reached, a light source is activated. Light is emitted from the light source in an amount greater that the pre-determined minimum-lumen threshold. The light source is then deactivated after a period of time, which may be variable and used in combination with other light-activation and de-activation systems.

BRIEF DESCRIPTION OF THE DRAWINGS

"For a more complete understanding of the present invention and for further objects and advantages thereof, reference may now be had to the following description taken in conjunction with the accompanying drawings in which:

"FIG. 1 is a schematic diagram of a DAIS according to an exemplary embodiment;

"FIG. 2 is a perspective view of the DAIS of FIG. 1 according to an exemplary embodiment;

"FIG. 3 is a front view of the DAIS of FIG. 1 according to an exemplary embodiment;

"FIGS. 4A-4D are rear views of the DAIS of FIG. 1 according to various exemplary embodiments;

"FIG. 5A is a flow diagram of a process for providing illumination to an interior of a dark area according to an exemplary embodiment; and

"FIG. 5B is a flow diagram of a process for providing illumination to an interior of a dark area utilizing a timer according to an exemplary embodiment."
