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...
