Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead technology, specifically to a mold-top focused LED lamp bead that is easy to position. Background Technology

[0002] LEDs are widely used in lighting, display and other fields due to their advantages such as high efficiency, energy saving and long life. Top-mounted focused LED chips are often used in scenarios where high light concentration is required due to their good light focusing effect.

[0003] However, the existing technology has the following drawbacks:

[0004] Existing top-mounted focused LED beads lack effective mechanical positioning structures during installation. Installers can only rely on visual judgment to roughly determine the position, which easily leads to installation deviations, especially when multiple beads are densely arranged. These deviations result in uneven light distribution, affecting the overall performance. Furthermore, while some beads have simple protective structures, the connection between the protective components and the bead body is not secure enough, making them prone to detachment during installation or transportation, thus failing to provide effective protection. Utility Model Content

[0005] The purpose of this invention is to provide a mold-top focusing LED light bead that is easy to position, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mold-top focused LED lamp bead for easy positioning, comprising a lamp holder, wherein positioning pins are provided at the four corners of the top of the lamp holder, and a first convex ring plate and a second convex ring plate are fixedly installed sequentially from the inside to the outside of the bottom of the lamp holder, and an annular groove is provided between the two, wherein an LED chip is embedded inside the second convex ring plate, and a lamp bead body is fixedly installed at the bottom of the LED chip, a protective cover is engaged inside the annular groove, and the protective cover covers the outside of the lamp bead body, and a sliding groove is provided in the middle of both sides of the top of the lamp holder, and a claw is slidably installed inside the sliding groove, wherein one side of the bottom of the claw is fixedly connected to the inner wall of one side of the bottom of the sliding groove by a spring, and a push rod is fixedly installed on the other side of its bottom.

[0007] Using the above technical solution, the positioning pin on the lamp holder corresponds to the positioning hole on the circuit board, which facilitates quick determination of the installation position of the lamp body and quick installation. The claw makes the lamp body engage with the slot on the mounting groove, resulting in a tight connection and secure installation.

[0008] The lamp holder is a square plate with rounded chamfers at the corners of its sides. The lower half of the positioning pin is cylindrical, and the upper half is symmetrically arranged with two semi-circular frustums. A through hole is provided in the middle of the lamp holder, and a protective sleeve is provided inside the through hole.

[0009] The above technical solution allows the through-hole to facilitate the passage of wires on the LED chip and their connection to the circuit inside the mounting cavity, while the protective sleeve protects the wires.

[0010] Both the slide groove and the claw are inverted L-shaped. The inner wall of the slide groove is bonded with a rubber pad. The width of the claw is smaller than the width of the slide groove and it is located in the middle of the slide groove. The end of the push rod away from the claw is provided with a circular plate, and the side of the circular plate away from the claw is bonded with a rubber pad.

[0011] Using the above technical solution, the claw can slide left and right inside the slide groove, making it easy to insert into the installation cavity when retracted, and playing a limiting and fixing role when ejected, while the rubber pad has a buffering and protective function.

[0012] A wire is fixedly installed in the middle of the top of the LED chip. The end of the wire away from the LED chip passes through the through hole and is located outside the protective cover. The LED chip is circular and its outer diameter is the same as the inner diameter of the first convex ring plate. The inner diameter of the second convex ring plate is larger than the outer diameter of the first convex ring plate.

[0013] Using the above technical solution, the wiring facilitates the connection between the LED chip and the circuit board inside the safety seat.

[0014] The inner walls on both sides of the second convex ring plate are provided with slots. The protective cover is hemispherical and has grooves on both sides of its top. The grooves are provided with elastic buckles. The top of the protective cover is inserted into the inside of the annular groove, and the elastic buckles are engaged and installed inside the slots.

[0015] Using the above technical solution, the protective cover is connected to the groove on the inner side of the second convex ring plate by elastic buckle, so as to ensure a tight connection and prevent it from falling off.

[0016] The inside of the annular groove is coated with adhesive, and a sealing ring groove is opened on the outer side of the top of the protective cover, and a sealing ring is fitted inside the sealing ring groove.

[0017] In this technical solution, the sealing ring is sandwiched between the protective cover and the second convex ring plate, and is compressed, thus enhancing the sealing performance.

[0018] The protective cover is made of acrylic material, and several ventilation holes are evenly distributed on the protective cover. The sealing ring is made of silicone.

[0019] Using the above technical solution, the acrylic protective cover has high transparency, which facilitates the transmission of light from the LED chip body.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The positioning pin on the top of the lamp holder and the claws on both sides of it can quickly determine the installation position, improve the installation speed and reduce the installation difficulty. The hook-shaped structure of the elastic buckle can firmly fix the lamp cover to the bottom of the lamp holder to prevent it from loosening after installation. The setting of the vent hole can balance the air pressure inside and outside the protective cover and prevent moisture from affecting the performance of the lamp beads due to temperature changes. At the same time, the protective cover can effectively block dust and debris from contaminating the lamp beads and causing collision damage. Attached Figure Description
