The invention relates to the technical field of LED lamps, and discloses a
breathing type LED heat dissipation lamp, which comprises a main body, a lamp groove is formed in the bottom of the main body, and an
LED lamp is clamped in the lamp groove. When anarc-shaped air bag which is gradually expanded drives an air outlet
pipe to move upwards to get close to a guide cavity, the arc-shaped air bag drives a patch to move upwards, the patch drives a heat dissipation
pipe to move upwards, a heat dissipation
pipe drives a phase-change rectangular block to move upwards, at the moment, the phase-change rectangular block stops absorbing heat to a heat conduction plate and releases heat, and at the moment, high-temperature air flow exhausted from the interior of the arc-shaped air bag drives heat air in a movable cavity to flow upwards to accelerate heat release of the
phase change rectangular block, when the arc-shaped air bag is contracted, the elastic force of the adjusting spring on the adjusting rod drives the phase-change rectangular block to be downwards attached to the inclined surface of the
heat conducting plate again, at the moment, the phase-change rectangular block is attached to the
heat conducting plate to guide out heat absorbed by the
heat conducting plate from the outer wall surface of the auxiliary pipe, the effect of accelerating dissipation of heat in the
LED lamp is achieved, and the heat dissipation efficiency in the movable cavity is improved.
