Description

Technical Field

[0001] The utility model relates to the technical field of light emitting diodes, in particular to a waterproof LED light emitting diode. Background Art

[0002] LED light-emitting diodes are made of compounds of gallium, arsenic, phosphorus, nitrogen and indium. They can radiate visible light when electrons and holes recombine. They are used as indicator lights in circuits and instruments, or to form text or digital displays. Light-emitting diodes are semiconductor components. As an efficient light source, they have many characteristics such as environmental protection, power saving and long life, and have been widely used in various fields.

[0003] Chinese patent CN210950829U discloses a waterproof LED light emitting diode, which relates to the technical field of LED light emitting diodes, including a lamp housing, a lampshade is installed on the top of the lamp housing, a substrate is arranged inside the lampshade, and the substrate is divided into a quartz sand layer and a plastic insulating layer from top to bottom. Light emitting diodes are installed on both sides of the top of the substrate. The waterproof LED light emitting diode can prevent excessive bending of the pins through the sleeve, the insulating layer, the steel wire and the screws, thereby causing damage to the pins, and will not affect the LED light emitting diodes, thereby improving the protection of the pins. The fluorescent layer on the top of the chip can increase the brightness of the chip, and a light-transmitting layer is provided at the same time to improve the brightness of the light emitting diode. The connection between the light emitting diode and the quartz sand layer is sealed by a sealing ring. The quartz sand layer increases the hardness of the substrate, reduces the probability of the plastic insulating layer being directly scratched, and enhances the waterproof effect of the light emitting diode.

[0004] The above patent seals the light emitting diode in the lamp housing and the lampshade when in use. However, the light emitting diode needs to be connected to the external control circuit by wires when in use, and the above patent lacks the wires and the function of sealing the wires. Therefore, in view of the above situation, it is urgent to develop a waterproof LED light emitting diode that is easy to assemble, overall sealed, and has good sealing protection for the wires to prevent water leakage, so as to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0005] The purpose of the utility model is to provide a waterproof LED light emitting diode to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A waterproof LED light emitting diode comprises a base, an isolation cover, a light emitting diode, a fastening screw, a mounting sleeve and a guide sleeve, wherein the isolation cover is mounted on the base, the light emitting diode is mounted on the inner side of the isolation cover on the base, a sealing strip inserted into the base is arranged at the lower end of the isolation cover, a card slot for inserting the sealing strip is arranged on the base, a mounting sleeve is fixed on the right side of the isolation cover, a guide sleeve is clamped in the mounting sleeve, a wire passing through the guide sleeve is mounted on the light emitting diode, a gradient hole for inserting the guide sleeve is arranged in the mounting sleeve, the diameter of the gradient hole gradually decreases from right to left, and the outer diameter of the left half of the guide sleeve is larger than the diameter at the smallest part of the gradient hole.

[0008] Preferably, the isolation cover is fixed to the base by fastening screws.

[0009] Preferably, the isolation cover is made of transparent material.

[0010] Preferably, the installation sleeve passes through the right side wall of the isolation cover.

[0011] Preferably, the base is provided with a plurality of mounting holes for bolts to pass through.

[0012] Preferably, the guide sleeve is made of rubber.

[0013] The beneficial effects of the utility model are as follows: when the waterproof LED light-emitting diode is used, the wire is passed through the guide sleeve, and then the guide sleeve is gradually pressed into the installation sleeve. Since the diameter of the gradient hole gradually decreases from right to left, and the outer diameter of the left half of the guide sleeve is larger than the diameter of the smallest part of the gradient hole, the guide sleeve will be gradually squeezed when it is gradually inserted into the gradient hole, so that the guide sleeve and the installation sleeve fit tightly together, and the extrusion deformation of the outer part of the guide sleeve will also cause its internal space to be compressed, so that the wire and the inner wall of the guide sleeve fit tightly together to prevent water leakage, and then the isolation cover is installed on the base, the sealing strip is inserted into the card slot, and the fixing screws are tightened to fix the isolation cover tightly to the base, thereby improving the sealing performance, and thus preventing water leakage at the connection between the base and the isolation cover. In summary, the utility model is easy to assemble, is generally sealed, and has good sealing protection for the wire to prevent water leakage. BRIEF DESCRIPTION OF THE DRAWINGS
