LED lamp scattering heat by exchanging currents

摘要

An LED lamp scattering heat by exchanging currents has a current guider disposed on a seat body. The current guider divides an accommodating chamber of the seat body into at least one first current channel and at least one second current channel. On a periphery of the seat body defines at least one first opening corresponding to the second current channel and at least one second opening defined near a fan of a cooling device. By guiding exterior currents out of the first opening via the second current channel, the exterior currents further enter the second opening of the seat body for being expelled out of the first current channel via the fan to complete an air flow circulation by exchanging currents, which increases the heat radiating efficiency and the using life of the LED lamp and remedies restrictions on installations of the lamp for expanding the lamp application.
