Abstract
A flashlight comprises a housing including a cavity adapted for receiving a battery and a reflector mounted to said housing and having a light-reflecting surface and a bore therethrough for receiving a lamp. The bore includes a circumferential groove therein and an annular ring or O-ring of resilient material in the groove. The lamp has a filament and has a pair of electrical leads at one end thereof. An electrical connector is mounted to the housing and engages the electrical leads of the lamp for holding the lamp in the bore of the reflector within the annular O-ring of resilient material for cushioning the lamp against physical shocks. Battery terminals in the cavity of the housing connect the lamp in circuit with the battery which provides electrical power for energizing the lamp filament to produce light. The reflector may be moveably mounted with respect to the lamp, such as by a rotatable threaded mounting of the reflector, for changing the relative position of the light-reflecting surface of the reflector with respect to the lamp filament thereby to change the focus of the beam of light produced.
