TECHNICAL FIELD OF THE INVENTION 
       [0001]    The present invention is directed to lights, and more particularly to a portable electric lantern having an apertured reflector and a clear top cap for the projection of illumination in an upward direction. 
       BACKGROUND OF THE INVENTION 
       [0002]    Portable electric lanterns are useful for a variety of different applications, including use for light in the outdoors, backup lighting in a power outage, or as a source of light to find an object in a dark location or to enable a user to work in areas of low light. A drawback to conventional electric lanterns, however, is that the lantern provides illumination that projects radially outward from the lantern through the globe, but there is a “black hole” directly above the lantern where little or no illumination is projected. 
       SUMMARY OF THE INVENTION 
       [0003]    The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the more detailed description that is presented later. 
         [0004]    In accordance with an embodiment, a electric lantern is provided. The lantern includes a clear top cap and a top reflector having apertures therein to allow illumination through the top reflector and to the top cap for projections in a direction above the lantern. 
         [0005]    Other features of the invention will become apparent from the following detailed description when taken in conjunction with the drawings, in which:

     DETAILED DESCRIPTION 
       [0013]    In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the present invention may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described. 
         [0014]    Referring now to the drawings, in which like reference numerals represent like parts throughout the several views,  FIG. 1  shows a lantern  10  in accordance with an embodiment of the invention. The lantern  10  includes a housing assembly  20  and a globe assembly  30 . The globe assembly comprises globe  32 , translucent top cap  34 , top cap sleeve  36 , top reflector  38 , bottom reflector  40  and light source  42 . 
         [0015]    Most illumination from the lantern is generating using the light source  42  and the bottom reflector  40  in the conventional manner. Light source  42  is located under bottom reflector  40  and projects illumination into the cavity created by globe  32  through the light source aperture  44  in bottom reflector. The majority of the illumination generated by light source  42  is projected radially outward through globe  32 . Globe  32  is translucent and is preferably made of polycarbonate or a similar material known in the industry. Globe  32  may comprise a texturized surface. 
         [0016]    Bottom reflector  40  is preferably metalized for maximum reflectance and light output. Bottom reflector  40  reflects the light generated from light source  42  outward through translucent globe  32 . 
         [0017]    Top cap  34  is translucent and is preferably made of polycarbonate or a similar material known in the industry. Top cap  34  comprises a curvilinear dome and has a cross sectional shape that compliments the shape of lantern globe  32 . As shown in  FIG. 1 , globe  32  is preferably generally cylindrical in shape. Almost any other shape, however, such as square, triangular or the like would also fall within the scope of the present invention. In such case, the bottom reflector, and top cap would preferably be of a shape complimentary to the shape of the globe. 
         [0018]    As shown in  FIGS. 3 and 4 , top reflector  38  is conical in shape to maximize reflectance of light generated from the light source  42  through the globe  32 . Top reflector  38  is also metalized to maximize reflectance. As shown in  FIGS. 2 and 3 , top reflector  38  also comprises through-cuts  50  which allow illumination to exit into the area between top reflector  38  and top cap  34  and to be projected outward through translucent top cap  34 . The apertures  50  in top reflector  38  operate to provide glow or illumination on the top side of lantern. 
         [0019]    Top reflector  38  comprises three elongated slots  50  which are shaped to compliment the shape of top reflector  38 . Although three slots  50  are depicted herein, it is within the scope of the present invention for top reflector  38  to comprise any number of apertures in any size, shape, location and/or orientation on top reflector provided that the overall surface area of top reflector is sufficiently maintained so as to provide adequate reflectance for the generated light. By way of a non-limiting examples, it is within the scope of the present invention for apertures  50  to comprise a multitude of circular apertures in a repeating pattern over the top surface of top reflector or for apertures  50  to comprise slots radiating outward from the center of top reflector like the spokes of a wheel. 
         [0020]    Housing assembly  20  comprises base  22 , base sleeve  24 , upper base sleeve  26  and battery power meter  28 . The lantern  10  also includes internal wiring (not shown) and a power switch  80  to allow a user to turn the light off and on using the switch. Base  22  includes bail hook  70  that is pivotally attached to the underside of base  22  to enable lantern  10  to be hung in an upside down orientation. 
         [0021]    Receptacle  54  is located on the underside of housing assembly  20  defining a cavity for receiving an interchangeable power pack  55 , as shown in  FIG. 7 . Preferably, the power pack  55  may be powered with batteries, rechargeable batteries, fuel cells and the like. It is also within the scope of the present invention for receptacle  54  to receive batteries (not shown) that may be mounted therein and secured with a bottom cap (not shown). 
         [0022]    Light source  42  may include any form of lamp, including a light emitting diode (LED), halogen lamp, an incandescent lamp, a fluorescent lamp, or other lamps or lights.
