led light waterproof structure

Abstract

The invention discloses a waterproof structure of an LED lamp. The waterproof structure comprises a casing and an LED assembly, wherein light transmitting holes are formed in the surface of the casing; embedding slots located in two opposite sides of the light transmitting holes are formed in the inner wall surface of the casing; the waterproof structure further comprises sealing strips, light transmitting components and supports; a through hole is formed in each sealing strip; a flange is arranged at one end of each light transmitting component; after the other end of each light transmitting component penetrates through the through hole in the corresponding sealing strip, at least one part of each light transmitting component is located in the corresponding light transmitting hole in the casing; each flange is tightly attached to the corresponding sealing strip; an accommodating groove is formed in each support; each LED assembly is located in the accommodation groove in the corresponding support; after each support is inserted into the corresponding embedding slots in the casing, the corresponding light transmitting component and the corresponding sealing strip are sequentially pressed between the corresponding support and the inner wall surface of the casing; and one part of the accommodation groove in each support corresponds to the through hole in the corresponding sealing strip. The waterproof structure disclosed by the invention has the advantage of good waterproof effect.

Description

technical field [0001] The invention relates to the waterproof design of electronic product circuits, in particular to an LED waterproof structure welded with a PCB board. Background technique [0002] The LED lights of existing electronic products are not waterproof enough after welding with PCB (Printed Circuit Board, printed circuit board). For example, in washing machines, the main control circuit and display circuit are usually designed on the same single panel, but buttons, display lights LED) has a height difference with other high-level components such as power supply components, thyristor heat sinks, buzzers, sockets, etc., which makes the buttons difficult to operate and the display light panel unsightly, so the buttons and display lights should be installed above On the high lamp stand of other devices, the electric control board is filled with glue and waterproofed in the electric control box. This method has factors such as high cost and difficult manufacturing ...

[0002] The LED lights of existing electronic products are not waterproof enough after welding with PCB (Printed Circuit Board, printed circuit board). For example, in washing machines, the main control circuit and display circuit are usually designed on the same single panel, but buttons, display lights LED) has a height difference with other high-level components such as power supply components, thyristor heat sinks, buzzers, sockets, etc., which makes the buttons difficult to operate and the display light panel unsightly, so the buttons and display lights should be installed above On the high lamp stand of other devices, the electric control board is filled with glue and waterproofed in the electric control box. This method has factors such as high cost and difficult manufacturing process. The whole is fully sealed and waterproof. Only the metal exposed part of the lower part of the component can be glued and waterproofed. If there is no glue sealing or waterproof and moisture-proof treatment, it is easy to short circuit or aging corrosion

And when there are many display lights to be set, it is difficult to accurately and quickly install light-emitting diodes (LEDs) with long and many pins on the PCB, and fix them at a specified height, and it is even more difficult to do waterproof treatment.
