ABSTRACT:
A drop-in light emitting diode (LED) module that can be used to increase the light output of a conventional flashlight includes a heat sink, a high power LED mounted on the heat sink, and an LED driver circuit. The driver circuit is designed to supply the LED with its maximum rated current so that its light output is brighter than the light output of conventional flashlights. The heat sink channels heat generated by the LED when receiving its maximum rated current into the body of the flashlight so the LED does not overheat and fail. The module is designed to be easily inserted into a conventional flashlight to increase its light output and removed when desired. The module can be used to create a modified flashlight by using the module with a conventional reflector that has been modified for use with the module.
