Description

Waterproof sealing device for LED ground plug lamp Technical Field The utility model relates to the technical field of lighting equipment, in particular to a waterproof sealing device for an LED ground plug lamp. Background The LED floor plug lamp is used as illumination decoration equipment commonly used in outdoor places such as landscape, squares, courtyards and the like, and is exposed in natural environment for a long time and needs to be subjected to severe conditions such as rainwater, humidity, ponding and the like. Compared with the prior art, the utility model has the advantages that the structural design is reasonable, the sealing waterproof performance is strong, the light emitting effect is good, the LED ground lamp can rotate in the horizontal plane and the vertical direction at the same time, the rotation irradiation of each angle is realized, and a larger expansion space is provided on the applicable occasion. However, the existing LED ground plug lamp has the defects of remarkable waterproof performance due to the fact that the waterproof structure of the existing LED ground plug lamp is mostly dependent on the traditional schemes such as single-layer sealing rings or silica gel dispensing filling, the simple sealing mode is easily affected by multiple factors such as ultraviolet rays, temperature difference changes and mechanical vibration in the long-term outdoor use process, so that the sealing rings are fast aged, hardened or deformed, once the sealing structure fails, rainwater, dew and ground penetrating water are extremely easy to permeate into the lamp body, faults such as short circuit of an LED light source and corrosion of a driving power supply are caused, and even the lamp is scrapped in severe cases, so that the requirements of modern landscape lighting on durability and economy of the lamp are difficult to meet. Disclosure of utility model (One) solving the technical problems The utility model aims to provide a waterproof sealing device for an LED ground plug lamp, which aims to solve the problem that the waterproof effect is poor due to a single-layer structure of the existing LED ground plug lamp in the background technology.
