A flashlight structure with a heat-dissipation device is disclosed. The flashlight
structure includes a base having a conducting point isolated with the base; a high-power
luminary disposed on the base and having an anode electrode connecting with the
conducting point and a cathode electrode connecting with the base; a power source
having a positive terminal connecting to the conducting point and a negative terminal
connecting to the base for providing the luminary with power; and a housing including
the base and having plural heat sink for dissipating the heat produced by the high-power
luminary, thereby preventing the flashlight from damage of device or diminution
of use life.
