Abstract:
1. A drop-in light emitting diode (LED) module for a flashlight, comprising: a heat sink having a main body and a wedge-shaped piece adjustably connected to the main body, the main body having a cylindrical shape, a flat upper portion, a substantially annular outer wall extending outward from the flat upper portion, a substantially annular inner wall extending outward from the flat upper portion, and a hollow portion separating the substantially annular outer wall from the substantially annular inner wall, the substantially annular outer wall being thicker than the substantially annular inner wall and the flat upper portion, the main body further including a sloped side portion, the wedge-shaped piece including a sloped inner portion, a curved outer portion, and a flat lower portion, the sloped side portion of the main body and the sloped inner portion of the wedge-shaped piece being positioned adjacent to one another; a high power LED connected to the heat sink; an LED driver circuit connected to the high power LED and disposed within the inner portion of the main body; and wherein, when the drop-in LED module is inserted into a flashlight body and power is supplied to the LED driver circuit using batteries included in the flashlight body, the LED driver circuit supplies a maximum rated current to the high power LED and the heat sink channels heat generated by the high power LED from the high power LED to the flashlight body.
