Sealing structure of housing and lampshade in LED lamps and its processing method

Abstract

The invention provides a sealing structure for a housing and a lampshade of an LED lamp. The sealing structure comprises the housing provided with an LED circuit board, wherein multiple LED light sources are arranged on the LED circuit board, the transparent lampshade covers the upper end of the housing, and a seal ring is arranged between the housing and the lampshade. The sealing structure further comprises a sealing barrier strip located on an outer ring of the seal ring, wherein the sealing barrier strip is also located between the housing and the lampshade and is in an extruded state. The seal ring is made of silica gel, the housing and the lampshade are fixedly connected through the seal ring made of the silica gel, and the outer edge of the seal ring extends outward to the inner side of the sealing barrier strip. The housing and the lampshade are fixed through the seal ring made of the silica gel, additional fasteners for fixing the lampshade are not needed, accordingly the product cost is reduced, and the attractive appearance and sealing performance of a product can be further ensured.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a sealing structure of a casing and a lampshade in an LED lamp and a processing method thereof. Background technique [0002] Before LED became a light source, light sources such as HID, CFL, and incandescent lamps were put into fixtures in the industry to form lamps. This requires that the lamps have an openable structure, and the light source can be accessed after opening for easy replacement. light source. Therefore, this kind of lamp needs to be installed with a sealing ring to ensure that the lamp still has good sealing performance after the lamp is closed. The sealing ring usually has several molding methods such as mold opening, extrusion, foaming or stamping. [0003] In recent years, with the development of LED technology, LED has been more and more widely used in the lighting industry, so the entire industrial chain has also undergone corresponding changes. Compared with traditional lam...

Problems solved by technology

[0004] Furthermore, at present, most of the LED lamps are manufactured using the production technology of traditional lamps, that is, a shell with a metal structure, an LED light source is installed in the shell, a tempered glass (that is, a lampshade) is covered on the shell, and the edge of the glass is made of silica gel. Strip wrap protection, so as to meet the IP protection requirements, but also play a role in shock absorption. However, the LED lamps with this structure also need to use additional fasteners such as bolts, screws, clips, etc. to fix the glass and the shell together. Thereby increasing the processing procedure of the whole LED lamps, inconvenient product assembly, increasing the cost of the product, and reducing the overall aesthetics of the product from the appearance
