Problems solved by technology

[0003] The LED lamp with this structure is more convenient to use, but when the LED lamp is used in a harsh environment, a large amount of impurities are prone to deposit on the lampshade. This situation is more common in factories with heavy dust. The impurities on the lampshade It will seriously affect the use effect of the entire LED lamp, and at the same time, the lampshade is easily damaged, making the entire LED lamp unusable

Abstract

The invention discloses an LED lamp with a dustproof outer cover. The LED lamp comprises a dustproof cover body and an LED bulb. The dustproof cover body comprises a circular-plate-shaped upper supporting plate and a protective cover. The protective cover is a cylinder with a cylindrical groove-shaped accommodating cavity formed in the upper end face. An internal thread is formed at the upper endof the accommodating cavity of the protective cover; the upper supporting plate is located in the accommodating cavity and connected to the upper end of the accommodating cavity of the protective cover in a threaded mode; a vertically-through circular hole-shaped through hole is formed in the center of the upper supporting plate; a circular ring-shaped elastic lower sealing ring is arranged on the side wall of the through hole; a circular ring-shaped upper limiting ring is arranged on the upper end face of the upper supporting plate in a lifting mode. The upper limiting ring is used for abutting against a bulb base on the upper side. A lamp holder of the LED bulb sequentially penetrates through the lower sealing ring and the upper limiting ring from bottom to top and is connected to the bulb base in a threaded or clamped mode. The protective cover is transparent.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED lamp with a dustproof outer cover. Background technique [0002] LED lamps are used more and more in people's production and life because of their advantages such as long service life and stable operation. The structure of the existing LED lamp is as follows: it includes a substrate, LED lamp beads, lamp holders and lampshades. line. When in use, just connect the lamp holder to the external power supply directly. [0003] The LED lamp with this structure is more convenient to use, but when the LED lamp is used in a harsh environment, a large amount of impurities are prone to deposit on the lampshade. This situation is more common in factories with heavy dust. The impurities on the lampshade It will seriously affect the use effect of the entire LED lamp, and at the same time, the lampshade is easily damaged, so that the entire LED lamp cannot be used anymore.
