Problems solved by technology

[0002] In the prior art, LED lamps usually include a PCB board and a lens installed directly in front of the light emitting direction of the PCB board. The lens is usually fixed and installed by screws, and in order to prevent water from penetrating into the lens and affecting the PCB board, it is usually installed at the installation place. There is a sealing ring, or the potting glue is filled in the gap between the lens and the LED luminous body of the PCB board. This kind of sealing structure connected by screws is very prone to water leakage at the sealing part due to the screw not being locked tightly. , the waterproof sealing is poor, and the inside of the lens is sealed with glue, which is very inconvenient for glue filling and not easy for production and processing

Abstract

The invention discloses a novel waterproof sealing structure for an LED lamp. The novel waterproof sealing structure comprises a mounting plane, a limiting frame, a PCB and a lens; the limiting frameis fixedly mounted on the mounting plane and encloses a mounting groove with the four circumferential faces closed; the PCB is arranged in the mounting groove, and a plurality of LED luminous bodies are mounted on the surface of the PCB; the middle of the lens is provided with light emitting parts matched with the LED luminous bodies in a one-to-one correspondence mode; a pressing edge attached tothe mounting plane is arranged at the edge of the lens; a sealant filling gap is formed between the pressing edge and the mounting groove and filled with a pouring sealant; and the pressing edge is wrapped with the pouring sealant, and thus the lens is fixedly mounted in the mounting groove. The novel waterproof sealing structure for the LED lamp is convenient to produce and process, high in production efficiency and good in waterproof sealing property.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a novel waterproof sealing structure of an LED lamp. Background technique [0002] In the prior art, LED lamps usually include a PCB board and a lens installed directly in front of the light emitting direction of the PCB board. The lens is usually fixed and installed by screws, and in order to prevent water from penetrating into the lens and affecting the PCB board, it is usually installed at the installation place. There is a sealing ring, or the potting glue is filled in the gap between the lens and the LED luminous body of the PCB board. This kind of sealing structure connected by screws is very prone to water leakage at the sealing part due to the screw not being locked tightly. , the waterproof sealing performance is relatively poor, and by filling the inside of the lens with glue, the glue filling is very inconvenient, and it is not convenient for production and proces...
