Flashlight

a flashlight comprising:

• (a) means for retaining two dry cell batteries;
• (b) a lamp;
• (c) means for electrically coupling said lamp and said batteries;
• and
• (d) a head assembly;
• wherein said head assembly comprises an elliptical conical reflector and a lens selected from the group:
• planar lens or negative lens;
• wherein said head assembly is movable such that the position of said reflector in movable relative to said lamp.

a flashlight which is portable and hand held, and which is capable of operating with one or more batteries, said flashlight comprising:

• (a) a chamber for retaining one or more batteries, wherein said chamber comprises a first opening for receiving one or more batteries;
• and a second opening substantially opposite said first opening;
• (b) an end cap removably connected to said chamber for selectively covering and uncovering said first opening;
• (c) a lamp bulb;
• (d) means for holding said lamp bulb, said means retained by said chamber at said second opening;
• (e) means for electrically coupling said means for holding a lamp bulb and one or more batteries in said chamber;
• (f) a conic reflector comprising a first central opening, a second central opening substantially opposite said first central opening, and a inner area defined by the space between said first central opening and said second central opening;
• (g) a lens;
• (h) means for fixedly positioning said lens relative to said lamp, wherein said means is removably connected to said opening of said chamber and rotatable relative to said chamber cause said conic reflector to move relative said lamp.

a flashlight comprising:

• a battery housing holding one or more batteries;
• a lamp bulb holder capable of holding a lamp bulb;
• and
• an electrical circuit extending from said battery housing to said lamp bulb holder for electrically coupling one or more batteries to a lamp bulb;
• wherein said lamp bulb holder includes means for holding a spare lamp bulb.

a flashlight comprising:

• a battery housing holding one or more batteries;
• a lamp bulb holder capable of holding a lamp bulb;
• and
• an electrical circuit extending from said battery housing to said lamp bulb holder for electrically coupling one or more batteries to a lamp bulb;
• wherein said electrical circuit comprises means to prevent electrical coupling unless said batteries are properly aligned within said chamber.

a flashlight comprising:

• (a) means for retaining two dry cell batteries;
• (b) a lamp;
• (c) means for electrically coupling said lamp and said batteries;
• and
• (d) a head assembly;
• wherein said head assembly includes an elliptical reflector having a first central opening, a second central opening substantially opposite said first opening, and an inner area defined by the space between said first central opening and said second central opening;
• wherein said head assembly further includes a lens selected from the group:
• planar lens or negative lens;
• wherein said head assembly is movable such that the position of said lamp may be varied within said inner area of said reflector to focus and defocus light illuminated by said lamp.

a flashlight capable of projecting light illuminated by a light bulb which is electrically coupled to one or more batteries, said flashlight comprising:

• (a) means for retaining one or more batteries;
• (b) means for holding a light bulb;
• (c) a reflector comprising a first central opening, a second central opening substantially opposite said first central opening, an inner area defined by the space between said first central opening and said second central opening, and a focal point;
• (d) a lens;
• (e) means for electrically coupling said means for holding a lamp bulb to one or more batteries retained by said means for retaining one or more batteries;
• (f) means for retaining said lens in a fixed position relative to said means for holding a light bulb wherein said lamp is moveable through said first central opening and within said inner area of said reflector;
• wherein said reflector reflects light rays illuminated by a light bulb positioned within said inner area of said reflector;
• wherein light illuminated by a light bulb positioned within said inner area of said reflector does not contain a light void about the center of the reflected light rays when the light bulb is not positioned at said focal point of said reflector.
