Abstract
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.
