Flashlight with luminescent housing having a tritium capsule

Abstract

A flashlight apparatus includes a quantity of tritium within a transparent capsule for emitting light independently of any power source for helping a person locate the apparatus in the absence of substantial external light. The tritium glows in the dark for many years without any external power source. The apparatus also includes the conventional elements of a power source, a primary light source, a power circuit for electrical communication between the power source and the primary light source, a switch, and a housing containing the power source, the primary light source. The light source is preferably a light emitting diode, and may alternatively be an incandescent bulb. The light emitting diode is preferably a high intensity, low power consuming light emitting diode. The transparent capsule includes a vial containing the tritium, which capsule provides a virtually unbreakable enclosure.
