Abstract
The invention discloses a sealed internal-circulation-forced LED (light-emitting diode) lamp. The lamp comprises a substrate, a fan, a sleeve frame and an outer cover, wherein the front face of the substrate is provided with a plurality of LED lamp bulbs, the fan is arranged at the back face or the side face of the substrate, the sleeve frame encloses at least one part of the fan, an air inlet is arranged around or behind the fan, the sleeve frame is provided with an air outlet in the blowing direction of the fan, and all the assemblies are enclosed and sealed by the outer cover. By arranging the fan in the sealed internal-circulation-forced LED lamp with the incorporation of the sleeve frame in the invention, the air in the sleeve frame can flow with the air outside the sleeve frame relatively when the fan rotates, so that the heat produced by the LED can be taken away, thereby distributing the internal temperature uniformly and preventing the LED luminous efficiency from lowering or a product from being burnt out as a result of the local overheating phenomena occurring near the LED lamp bulbs.
