It looks to me like what he has patented, unless there are other patents that I have not found, boils down to a heatsink to carry heat from the LED to the body of the light. It doesn't state the material of the heat sink anywhere.BRIEF SUMMARY OF THE INVENTION
The present invention includes a drop-in LED module that can be inserted into a conventional flashlight to increase the light output of the flashlight. The module includes a heat sink, a high power LED, and an LED driver circuit. The LED is mounted on the heat sink and designed to receive its maximum rated current. The driver circuit is connected to the LED, mounted on the heat sink, and designed to supply the LED with its maximum rated current. The heat sink is designed to be inserted into the flashlight body of the flashlight so that the driver circuit receives power from batteries included in the flashlight and supplies the maximum rated current to the LED. Heat generated by the LED when it receives this current is channeled away from the LED by the heat sink into the flashlight body. The present invention also includes a conventional flashlight reflector modified so that it can be used with the module of the present invention to create a new modified flashlight with a light output that is greater than the light output of conventional flashlights.
The light output generated by the LED of the present invention is brighter than the light output generated by conventional LED flashlights because the LED is supplied with its maximum rated current. The LEDs used in conventional LED flashlights are generally not supplied with their maximum rated currents because they are not properly heatsinked, overheat, and fail. In some prior art LED flashlights, the LEDs are supplied with their maximum rated currents until they begin to overheat, at which time control circuitry in these flashlights reduces the current, and the corresponding light output, to a lower current level in order to prevent the LEDs from overheating. The module of the present invention, however, includes a heat sink that allows the LED used in the present invention to be continually driven at its maximum rated current because it dissipates the heat that would otherwise damage the LED in the flashlight body used with the invention.
I have a lonely M61 sitting around with no host.
I really want as much regulated runtime as possible.
Does anyone know about how much regulated runtime I would get with the MD4 with 2 18650 2600 mAh batteries?
Would it be much more than 2 cr123s?
