Problems solved by technology

However, the weight of the aluminum sheet makes the LED light overall heavier, which is not conducive to the application. In addition, because the expansion ratio of the aluminum material and the plastic material is greatly different when it expands with heat and contracts with cold, the injection molding process parameters must be strictly controlled during injection molding. It will lead to cracking of the outer plastic parts of the processed products, and the mass-produced products can never achieve 100% zero defects, which will reduce the electrical safety of the products, and at the same time, the appearance will deteriorate, which will give users the impression of inferior products
If the embedded parts are stamped and formed by aluminum parts, due to the limitations of the process, the stamped and formed process can only process parts with the same wall thickness, and the product cannot process columns, steps, ribs, and different wall thicknesses. Larger limitations

Abstract

The invention discloses an LED lamp outer shell. The LED lamp outer shell comprises a plastic outer shell; a heat conducting plastic insert is embedded in the inner side of the plastic outer shell; and the plastic outer shell and the heat conducting plastic insert are of an integral structure through injection molding. The LED lamp outer shell is excellent in heat dissipating effect and low in weight.

Description

technical field [0001] The invention belongs to the technical field of LED lamps, and in particular relates to an LED lamp shell, a manufacturing method thereof and an LED lamp. Background technique [0002] The LED lamp includes a casing, and a circuit board is arranged inside the casing, and a power supply module and LED lamp beads are installed on the circuit board. During the use of the LED lamp, the circuit board will generate heat. Therefore, a heat sink is usually provided on the back of the circuit board, or an aluminum heat sink is injected and embedded on the inner wall of the housing for heat dissipation. However, the weight of the aluminum sheet makes the overall weight of the LED lamp heavy, which is not conducive to the application. In addition, because the expansion ratio of the aluminum material and the plastic material is greatly different when it expands with heat and contracts with cold, the injection molding process parameters must be strictly controlled ...
