Problems solved by technology

[0002] Existing high-power LED lamps all need to be provided with a heat sink, and the better the heat dissipation effect, the higher the power of the LED lamp. The back of the aluminum plate where the lamp beads are fixed, the heat transfer from the lamp beads to the back of the aluminum plate can only rely on the aluminum plate itself, limited by the structure of the heat pipe itself, the heat pipe can only contact a small part of the back of the aluminum plate, so that the heat on the aluminum plate Can not be transferred quickly to the heat pipe

Abstract

The invention relates to a high-power light-emitting diode (LED) lamp. The high-power LED lamp comprises a radiating plate, and a unit LED lamp of which the radiating surface is fixed in front of the radiating plate. The high-power LED lamp is characterized in that: a closed accommodating cavity is formed in the radiating plate; high-efficiency heat energy transfer liquid is filled in the closed accommodating cavity; and the side, which is far away from the unit LED lamp, in the closed accommodating cavity is provided with a plurality of grooves. Compared with the prior art, the high-power LED lamp has the advantage that: the heat of an aluminum plate fixedly connected with an LED lamp bead can quickly flow away, so that the temperature of the LED lamp bead is effectively and quickly reduced.

Description

technical field [0001] The invention relates to an electric light source. Background technique [0002] Existing high-power LED lamps all need to be provided with a heat sink, and the better the heat dissipation effect, the higher the power of the LED lamp. The back of the aluminum plate where the lamp beads are fixed, the heat transfer from the lamp beads to the back of the aluminum plate can only rely on the aluminum plate itself, limited by the structure of the heat pipe itself, the heat pipe can only contact a small part of the back of the aluminum plate, so that the heat on the aluminum plate Can not be quickly transferred to the heat pipe. Contents of the invention [0003] The object of the present invention is to provide a high-power LED lamp in which the heat energy of the aluminum plate fixedly connected with the LED lamp bead can flow away quickly, thereby effectively and rapidly reducing the temperature of the LED lamp bead. [0004] The present invention...
