Lamp sealing ring and lamps

Abstract

A sealing ring of a lamp and a lamp. The sealing ring includes: a ring-shaped body with a through hole in the center and a plurality of barbs arranged on the ring-shaped body; a hollow hole is arranged in the center of the section of the ring-shaped body, and the hollow hole passes through The entire ring-shaped body forms a closed cavity, which is filled with gas; the outer surface of the ring-shaped body is surrounded by two end faces and two side faces, the two end faces are parallel to each other, and the two side faces are connected between the two end faces. A plurality of barbs are distributed in pairs, and one barb in each pair of barbs protrudes around the inner surface of the ring-shaped body for a circle, and the other barb in each pair of barbs protrudes around the inner surface of the ring-shaped body. The outer surface of the ring-shaped body is circled in the circumferential direction; the width of the ring-shaped body is gradually reduced from one end face to the other end face, and the barbs arranged on the same side face are gradually increased along the direction in which the wider end faces the narrower end face. large size. The sealing ring of the lamp is easy to assemble, has good sealing effect, and prolongs the service life of the lamp.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a sealing ring applied on the end face of a lamp. Background technique [0002] The luminaire includes a luminaire shell and a light bulb, an optical component and a circuit component in the shell. In order to facilitate replacement of the light bulb and maintenance, the luminaire shell is usually composed of two parts, namely the front shell and the rear shell. The two parts are connected by a hinged structure and passed through Snap closure. Generally, the sealing performance of the sealing ring is directly related to the service life of the lamp. In order to improve the sealing performance of the lamp and achieve the effect of waterproof and anti-corrosion, it is necessary to seal the end faces of the front shell and the rear shell. A common practice is to use a sealing ring to seal the contacting end faces of the front shell and the rear shell. Sealing rings are divided into solid sea...

AI Technical Summary

Problems solved by technology

Sealing rings are divided into solid sealing rings and hollow sealing rings. Solid sealing rings are difficult to fit into the sealing groove due to difficulty in deformation. Compared with the solid sealing ring, there is a hollow hole in the center of the cross section. The hollow hole makes the sealing ring have a certain deformation space, so it is easier to fit into the sealing groove, but the hollow sealing ring is less subject to the shell pressure. Under the negative pressure inside the lamp and the washing of external water, it is easy to be distorted and deformed, which will affect the sealing effect
