Full Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to lighting fixtures and, more specifically, to a light fixture mounted in a window to shine out in order to obstruct a view inside, while providing those inside a lit view outside. 
     2. The Prior Art 
     A number of trends have come together to make many people more concerned about their privacy. One trend is increasing wealth, which increases the desire for privacy. Another is that as people move around the country more often, they less often know their neighbors very well. This all comes together with people more and more interested in keeping others from looking through their windows into the house. 
     Traditionally, privacy in a house has been implemented through shutters, followed by curtains, and more recently, blinds and other window treatments. One disadvantage of these approaches to privacy is that the measures that they take to keep people from looking through windows from the outside typically makes it more difficult to see through the windows from the inside. 
     BRIEF SUMMARY OF THE INVENTION 
     A lighting system includes a lighting unit and a mounting structure. Light from the lighting unit is mounted adjacent to a window to shine outward, obstructing a view of the inside of a space such as a house, commercial space, car, boat, etc., while allowing those inside a clear, lighted view of the outside. The lighting unit may be powered by electrical wiring, battery, or solar. Light is preferably adjustable in various directions. The lighting system provides additional security and privacy.

     DETAILED DESCRIPTION 
       FIG. 1  is a diagram showing a front view of an adjustable lighting system having a lighting unit  10  mounted in a window  12 , in accordance with one embodiment of the present invention. The lighting unit  10  has a light source that is directed through a lens  14 . The lighting system also includes a mounting arm  16 . The lighting unit  10  is shown adjustably attached to the mounting arm  16  that mounts outside the window  12  frame to, for example, the wall, the window sill, the ceiling, or otherwise to allow the light source in the light fixture to direct light out through the window  12 . In this embodiment, the lighting unit  10  attached to the mounting arm  16  may be adjustable as to direction. For example, the light may be adjusted up, down, right, or left. The lens may also be adjustable as to focus. This allows the light to be adjusted to maximize illumination at a specific distance, or be de-adjusted to minimize impacting neighbors. The light is typically mounted adjacent to the window  12  in order to minimize reflected glare from the light, while maximizing its ability to obstruct a view of the inside. Persons skilled in the art will appreciate that while illustrative embodiments are shown in the context of a house, the present invention is applicable to other enclosed spaces such as commercial buildings such as offices, automobiles and trucks, recreational vehicles, boats, etc. 
     The light source is typically electrically powered. This may be accomplished, for example, by running a wire down inside of or along side of the mounting arm  16  from a power source outside the window. Another alternative is to supply the electricity to the light source with batteries. In yet another embodiment, the light may ultimately be solar powered, with the light charging a battery during the day, and then utilizing the battery to power the light after dark. Other sources of power are also within the scope of the present invention. The lights may be turned on and off by electronic or electro-mechanical switches, timers, with a light sensor, or remotely, utilizing, for example, X10 technology which typically communicates over AC power lines within a home, or a combination of one or more of these techniques. Other methods of turning the lights on and off are also within the scope of the present invention. 
     The type of light source utilized may also vary with different embodiments of the present invention. The light source may be incandescent, fluorescent, LCDs, LEDs, or may be other light source types, currently available, or later invented. LCDs and LEDs are very attractive in this invention since they can produce significant glare without generating as much light shining into a neighbor&#39;s windows. Other types of lights are also within the scope of the present invention. The light source may have more than one level of brightness, such as a two-level system with a high and low brightness output. In one embodiment, the lights are relatively white in color, while in other embodiments, other light colors are utilized. Furthermore, a “mood light” may be mounted on the back of the light fixture to provide soft illumination in the room containing the light. 
     The light can be used on residential and commercial properties, recreational vehicles and tents. One or more lights can be placed on windows, doors (since many have windows on them to look through), and garage doors that often have windows on them. The shape of the light or lighting unit may be square, rectangular, triangular, or round. The light may also take the form of a pendulum; a light that is fixed on the ceiling or wall, which shines out of the window. Other shapes and configurations are also within the scope of the present invention. 
     Furthermore, the lighting system may include a security camera or other security device, either mounted separately or integrated into the lighting system. The focus of the lens  14 , or other parameters such as the brightness of the light source, may be dynamically adjusted by the security system, for example, on command, or in response to a motion, heat, or other detector. The system may also provide an audible warning comprising either a verbal warning or other sound. 
       FIG. 2  is a rear view of the lighting unit  10  shown in  FIG. 1 . The rear of the lighting unit is shown in a window  12 , along with the mounting arm  16  from which the light source is attached. 
       FIG. 3  is a side view of the lighting unit  10  shown in  FIGS. 1 and 2 . The lighting unit  10  is shown supported by a mounting arm  16 . Also shown in this FIG. is a lens  14  that may be adjustable in order to focus or unfocus the light being emitted by the light source. 
       FIG. 4  is a front view of a lighting unit  10 , in accordance with another embodiment of the present invention. A lens  14  is shown attached to the front of the light source. The lens  14  may be adjustable in order to focus or unfocus the light being emitted by the light source. 
       FIG. 5  is an exemplary view of the outside of a window  12  looking in, with a light active. The light shown from the light source is somewhat unfocused in this FIG., in order to reduce the amount of light that might affect neighbors. 
       FIG. 6  is a diagram showing a house with seven lighting systems emitting light, in accordance with one embodiment of the present invention. The lighting system is shown in four windows, the window in the front door, and in two windows in the attached garage. As can be seen in  FIGS. 5 and 6 , the present invention makes it difficult to see through a window into a house or business. 
     Those skilled in the art will recognize that modifications and variations can be made without departing from the spirit of the invention. Therefore, it is intended that this invention encompass all such variations and modifications as fall within the scope of the appended claims.
