A led light structure

Abstract

The invention belongs to the field of LED lamps, and aims to provide an LED lamp structure with high heat dissipation performance. According to the technical scheme, the LED lamp structure comprises aplate body, wherein a mounting substrate, a first semiconductor refrigeration piece, a heat conduction plate, a second semiconductor refrigeration piece and a heat dissipation block are sequentiallyarranged on the upper surface of the plate body in the direction away from the plate body; LED lamp beads are arranged on the face, facing the plate body, of the mounting substrate; receding holes areformed in the positions, opposite to the LED lamp beads, of the plate body; the heat dissipation block is in a table shape with a small upper part and a large lower part; a plurality of heat dissipation fins are uniformly arranged on the side surface of the heat dissipation block; the heat dissipation fins extend in the slope direction of the side surface of the heat dissipation block; and an airguide channel with a small upper part and a large lower part is formed between every two adjacent heat dissipation fins. The LED lamp structure has extremely high heat dissipation performance and isparticularly suitable for high-power LED lamps.

Description

technical field [0001] The invention belongs to the field of LED lamps, and in particular relates to an LED lamp structure with high heat dissipation performance. Background technique [0002] LED is the abbreviation of light-emitting diode, which is made by the principle that electrons and holes can radiate visible light when they recombine. Compared with traditional incandescent lamps, neon lamps, high-pressure sodium lamps, etc., it has low working voltage, low working current, good shock resistance and shock resistance, high reliability and long life. However, during the use of LEDs, heat generation has always been an important issue restricting its development, and a major factor affecting its service life and luminous efficiency. For this reason, the existing LED lamps are usually provided with a special heat dissipation structure. The heat dissipation structure generally connects the mounting substrate of the LED lamp bead with the heat dissipation plate, and the hea...

AI Technical Summary

Problems solved by technology

The increase in temperature of the heat sink causes the heat conduction between the mounting substrate and the heat sink to slow down, and a large amount of heat accumulates on the mounting substrate, causing the LED lamp beads to burn out

In short, the LED lamps in the prior art not only have a slow heat dissipation speed, but also the areas of high-temperature silt appear near the mounting substrate, causing high-power LED lamps to be easily burned due to high temperature and have a short service life.
