Abstract

A module, or collection of discreet components, for an LED flashlight is coupled to a conventional flashlight body which includes a conventional power source. The module comprise a housing adapted to be coupled to the flashlight body; an LED light source coupled to the power source; a heat sink coupled to the housing, which heat sink is thermally and mechanically coupled to the LED light source; and a reflector coupled to the housing and having an optical axis. The LED light source is positioned by the heat sink on or near the optical axis and is optically coupled to the reflector. The reflector reflects light from the LED light source in a forward direction. The module, and/or components, is arranged and configured to be operatively coupled as a unit to the flashlight body and power source.
