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.

LED lamp scattering heat by exchanging currents

An LED lamp scattering heat swiftly by exchanging currents mainly constructs multiple channels interleaved in heat scattering areas among fin units of a cooling device. At least one first hole is defined on a wall of each channel for assisting the channels in communicating with the heat scattering areas. Accordingly, the exterior air is introduced from the channels into an accommodating chamber of a seat body of the LED lamp. Thence, a fan installed in the LED lamp further blows the exterior air and the wasted heat of the LED unit to cause a current exchanging effect. Whereby, the wasted heat is efficiently expelled from the LED lamp, which increases the heat radiating efficiency and the using life of the LED lamp and remedies restrictions on installations of the LED lamp for expanding the lamp application.
