Technical Field

[0001] This utility model relates to the field of LED lamp bead technology, specifically a ceramic LED lamp bead with an adjustable structure. Background Technology

[0002] LED chips, as solid-state semiconductor devices that efficiently convert electrical energy into visible light, are widely used in modern lighting and many electronic devices. Among them, LED chips made using ceramic substrate technology have a long lifespan due to their excellent heat dissipation performance. However, existing ceramic LED chips still exhibit some problems that urgently need to be addressed in practical applications.

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

[0004] Most ceramic LED beads lack flexible adjustment functions, making it difficult to effectively adjust key parameters such as light color, brightness, and illumination angle according to different usage scenarios and user needs. This greatly limits their application range and user experience. Furthermore, the existing heat dissipation structure and methods of ceramic LED beads need further optimization. Utility Model Content

[0005] The purpose of this invention is to provide a ceramic LED bead with an adjustable structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ceramic LED lamp bead with an adjustable structure, comprising a lamp holder and a base. An LED chip is fixedly installed in the middle of the top of the base, and a lamp cover is fixedly installed on the top of the base, covering the outside of the LED chip. Clamping plates are symmetrically arranged on both sides of the bottom of the base. A connecting block is provided in the middle of the top of the lamp holder. A second mounting hole is opened in the middle of the two clamping plates. A first mounting hole is opened in the middle of the connecting block. The first mounting hole and the second mounting hole are correspondingly arranged, and a damping rotation connecting shaft is sequentially inserted inside them. A cavity is opened inside the top of the lamp holder, and a circuit board is fixedly installed on the inner wall of the bottom of the cavity. A brightness and color adjustment module is provided on the circuit board.

[0007] Using the above technical solution, the ceramic LED lamp and the lamp holder are rotatably connected by a damped rotating connecting shaft, which facilitates the adjustment of the angle and direction of the ceramic LED lamp. The brightness and color adjustment module on the circuit board can adjust the brightness and color of the LED lamp.

[0008] A threaded hole is provided in the middle of the bottom of the lamp holder. A second through hole is provided on one side of the top inner wall of the threaded hole. A protective sleeve is inserted into the second through hole. A second wire is fixedly installed at one end of the top of the circuit board. The end of the second wire away from the circuit board passes through the second through hole and is located inside the threaded hole.

[0009] Using the above technical solution, the threaded hole facilitates fixed installation on various equipment or support surfaces via threaded connection, and the protective sleeve protects the second conductor from wear by the inner side of the second through hole.

[0010] A third through hole is provided on one side of the base, and a first through hole is provided on one side of the top of the lamp holder. A first wire is fixedly installed on the side of the LED chip near the third through hole.

[0011] Using the above technical solution, the first wire connects the LED chip and the circuit board to provide power to the LED chip.

[0012] The base includes a base plate, a heat-conducting plate and a heat dissipation plate. The outer periphery of the top of the base plate is fixedly connected to the bottom of the lampshade. Several first heat dissipation holes are evenly opened on the base plate.

Several slots are uniformly opened on the bottom periphery of the heat-conducting plate, and several connecting posts are uniformly opened on the top periphery of the heat sink. The connecting posts are correspondingly arranged with the slots, and the two are engaged and connected.

[0015] By adopting the above technical solution, the heat generated by the ceramic lamp is evenly transferred to the heat sink by utilizing the rapid heat conduction and heat diffusion function of the heat-conducting plate, thereby improving heat dissipation efficiency.

[0016] The slot is coated with glue, and the connecting post is bonded to the slot with glue. Several heat dissipation fins are evenly distributed on the top of the heat dissipation plate, and the top of the heat dissipation fins is tightly attached to the bottom of the heat conduction plate. The heat dissipation fins are inclined strips, and the heat dissipation plate and heat dissipation fins are made of aluminum alloy. Several second heat dissipation holes are evenly opened on the heat dissipation plate.

[0017] Using the above technical solution, the adhesive plays a reinforcing role, preventing the heat sink from falling off, and the heat sink fins increase the surface area, thus enhancing the heat dissipation effect.

[0018] The lampshade is hemispherical and made of frosted ceramic material. The base has raised strips on both sides of its bottom, and the raised strips are made of rubber. A rubber pad is attached to the bottom of the lamp holder.

[0019] The above technical solution features a raised strip that facilitates the rotation of the ceramic lamp. The strip is made of rubber and has a heat insulation effect.
