High-power LED (Light Emitting Diode) bulb lamp

Abstract

The invention relates to a high-power LED (Light Emitting Diode) bulb lamp, which comprises a lamp cap, a radiating assembly, an aluminium substrate and a lampshade, wherein a driving power source is arranged inside the lamp cap; the radiating assembly is fixed to the bottom of the lamp cap; the radiating assembly comprises a heat conduction plastic piece; a tubular aluminium piece is fixed to the inner wall of the heat conduction plastic piece by heat conduction adhesive; a tooth-shaped radiating sheet is arranged on the outer wall of the heat conduction plastic piece; the lampshade is fixed to the bottom end of the heat conduction plastic piece; the aluminium substrate fixed to the bottom of the heat conduction plastic piece is arranged inside the lampshade; the aluminium substrate is connected with the driving power source by power lines; and a plurality of LED lamp beads are arranged on the bottom end face of the aluminium substrate. The high-power LED bulb lamp has the advantages that the structure is simple; the heat conduction plastic piece is adopted as a radiating element; the tubular radiating aluminium piece is arranged on the inner wall of the heat conduction plastic piece; the tooth-shaped radiating sheet is arranged on the outer wall of the heat conduction plastic piece; the whole radiating effect is good; the weight is light; the steps of fixing the heat conduction plastic piece, the lamp cap and the lampshade are simple; and the service life is long.

Description

technical field [0001] The invention relates to a high-power LED bulb lamp. Background technique [0002] Existing high-power LED bulb lamps usually use a large-area aluminum heat sink or ceramic heat sink to dissipate heat from the LED light-emitting chip and the substrate on which it is located. The high-power LED bulb lamp of the component has disadvantages such as high weight of the whole lamp, high cost, and complicated assembly process, resulting in high production costs, poor heat dissipation performance, and short service life. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a high-power LED bulb lamp with simple structure and convenient use, which has good heat dissipation effect and light weight. [0004] The high-power LED bulb lamp of the present invention includes a lamp cap, a heat dissipation assembly, an aluminum substrate and a lampshade. The inside of the lamp cap is provided with a drivin...
