Abstract

The invention relates to a cooling device of a lamp, in particular to a light emitting diode (LED) lamp cooling system. The LED lamp cooling system mainly solves the technical problems that in the prior art, a cooling structure of an LED lamp is large in occupied volume, gasified cooling can not be performed, the cooling structure is not environment-friendly, cooling effect is poor and the like. The LED lamp cooling system comprises a heat absorption device (2) arranged in an LED lampshade (1) and is characterized in that the heat absorption device (2) is closely adhered to a heating portion of the LED lamp. The heat absorption device is connected with a heat dissipation device through more than one connecting tube (3). The heat absorption device and the heat dissipation device are two separated and independent spaces. The whole heat dissipation device is in a hollow design. The heat absorption device, the connecting tube and the heat dissipation device are integrally arranged and are made of heat conduction materials in a casting or welding mode.

Description

technical field [0001] The invention relates to a heat absorbing device for a lamp, in particular to a cooling system for an LED lamp. Background technique [0002] At present, the known LED light source cooling technology generally uses self-cooling or forced air cooling in the lamp. The heat transfer medium of self-cooling or forced air cooling is air. The air heat transfer coefficient is low and the cooling effect is poor. The LED light source cooling problem Has not been well resolved. The Chinese patent discloses a cooling structure for LED liquid cooling (authorized announcement number: CN 2922124Y), which includes a cooling head and an LED substrate or LED chip. The cooling head is integrated on the back of the LED substrate or LED chip. There are micro-channels for the flow of liquid coolant, and the cooling head has a cooling medium inlet and outlet connected to the micro-channels; the micro-channels are set on one side of the cooling head or on the side of the LED...
