Abstract: A flashlight in accordance with the present invention includes a chamber, end cap, head assembly and lamp holder assembly. The end cap includes a bowed tripod portion to facilitate standing the flashlight on a flat surface. The head assembly includes a reflector and a lens. In one embodiment of the invention, the head assembly includes an elliptical reflector. In accordance with another embodiment of the present invention, the flashlight having a elliptical reflector is matched with a negative or planar lens. In accordance with another embodiment of the present invention, the head assembly includes an hyperbolic reflector. In accordance with another embodiment of the present invention, the flashlight having a hyperbolic reflector is matched with a positive or planar lens. In accordance with another aspect of the present invention, the flashlight includes electrode connections which prevent the conduction of electrical energy from batteries which are improperly aligned within the flashlight.

Abstract: A flashlight with unique flashlight electrical connections, including a switch structure featuring a switch requiring a small amount of force, and a short stroke distance to actuate, attached to a member on which a circuit adding additional functions to the flashlight may be located. The member has conductive springs attached to either end that are used to complete the electrical circuit with the battery and the lamp, while their compressive force is absorbed by a housing protecting the switch structure. A conductive strip is used to improve the conductivity of the circuit in a metal flashlight which has been provided with an electrically resistive protective coating.

Abstract: An improved flashlight includes a barrel, a light source and a variable length conductor. The barrel contains a plurality of batteries which may be arranged end-to-end. The light source is held in a holder. The variable length conductor is interposed between the plurality of batteries and the light source. The variable length conductor is configured to selectively electrically couple or de-couple the light source and the batteries. The holder of the light source may further be configured to move the light source substantially laterally relative to an axis of the reflector.

Abstract: A flashlight as disclosed to comprise a barrel, a tail cap, a head assembly, and a miniature lamp bulb holder and for providing interruptible electrical coupling to dry cell batteries retained within the barrel. One-way valves may be positioned at seal locations in association with passageways to allow venting of overpressure within the interior volume of the flashlight.

Abstract: A flashlight having a head assembly, a switch assembly and a removable tail cap with a spare bulb holder provided by the tail cap. The spare bulb holder includes a resilient body having an internal, U-shaped wall defining a slot configured to receive a flashlight bulb, a cylindrical wall about the slot and ribs extending between the U-shaped wall and the cylindrical peripheral wall. The slot extends through the cylindrical peripheral wall and includes a first section for receiving the plug of a flashlight bulb, a second section for receiving the flange of a flashlight bulb and a third section for receiving a lens of the flashlight bulb.

Abstract: A flashlight has a switch housing in between the battery compartment and reflector. The neck of the switch housing holds a lamp support at a central position within a reflector. An o-ring on the rear of the switch housing seals the battery compartment. The switch housing partially floats within the flashlight tube to allow for a slight adjustment of the lamp relative to the reflector to insure centering.

Abstract: A flashlight having features that align the light source of a lamp with the principal axis of a reflector, such flashlight having a head assembly that includes a reflector and a lens. The reflector has a central opening that surrounds the principal axis of the reflector. The light source of the flashlight is held by a lamp base and an axis of the lamp base is aligned with the light source. Particularly, the hottest portion of the light source may be aligned with the lamp base axis. The self-centering characteristic of the lamp base is configured with a non-cylindrical feature to be seated in a base receiver. The base receiver includes a receiver axis that is aligned with the principal axis of the reflector. The lamp can include a pair of electrodes and a filament light source extending between the electrodes.

Abstract: A portable, battery-operated flashlight having improved pivoting, switching and focusing features is disclosed. In one aspect of the invention, the flashlight takes the form of an attachment to a head gear for hands free use. In another aspect of the invention, the flashlight takes the form of a head lamp held in place on an user's head by an elastic band. The pivot connection between the body and the base, as well as the serrations on an exterior surface of the body, allows a user to adjust any angular direction of the light as desired. In another aspect of the invention, the flashlight takes the form of a long-handled flashlight having improved switching and focusing capabilities, such that axial movement of the switching assembly turns the flashlight “on” or “off”, as well as causing a position of the lamp to vary in order to focus or defocus the light.
