Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides, for example Figures 1-4The diagram illustrates a high-voltage four-color mixed white LED bead based on polycrystalline series connection, comprising a housing 101, a lampshade assembly, a positioning mechanism, and a pop-up mechanism. The top of the housing 101 has spaced mounting holes 102, into which LED beads 103 are inserted. The lampshade assembly is positioned on top of the LED beads 103. The positioning mechanism is located between the lampshade assembly and the housing 101. The pop-up mechanism is located at the bottom of the lampshade assembly. Each LED bead 103 encapsulates multiple LED chips, which are connected in series. This allows for voltage superposition, direct matching with high-voltage drives, reduced current requirements, and improved energy efficiency. Four different colors of LEDs can be used. LED chips, such as red, green, blue, and amber, are mixed to produce high color rendering white light. When the LED bead 103 is working, the light can directly pass through the lampshade assembly. The lampshade assembly is fixed to the housing 101 by a positioning mechanism, so that the LED bead 103 can work stably. When it is necessary to replace a certain LED bead 103, the lampshade assembly can be quickly removed from the housing 101 with the cooperation of the positioning mechanism and the pop-up mechanism. Then, the LED bead 103 to be replaced can be removed and replaced with a new one. Then, the lampshade assembly can be fixed by the positioning mechanism, thus improving the convenience of replacing the LED bead 103.

[0035] The lampshade assembly includes a slot 201, a cover ring 202, and a light-transmitting plate 203. The slot 201 is formed at the top of the inner wall of the mounting hole 102. The cover ring 202 is inserted into the inside of the slot 201. The light-transmitting plate 203 is fixedly connected to the inner wall of the cover ring 202. The cover ring 202 is locked inside the slot 201, which allows the light-transmitting plate 203 to position the LED bead 103, enabling the LED bead 103 to work stably. After the slot 201 is formed in the inner wall of the mounting hole 102, the top of the LED bead 103 is located in the slot 201, which makes it convenient for workers to remove the LED bead 103 from the mounting hole 102, further improving the convenience of replacing the LED bead 103.

[0036] The positioning mechanism includes an annular groove 301 and a positioning rod 302. The annular groove 301 is formed on the outer wall of the cover ring 202. The inner wall of the groove 201 has a movable hole 303. The positioning rod 302 is movably inserted into the inner wall of the movable hole 303 and the inner wall of the annular groove 301. A pressing mechanism is provided inside the movable hole 303. The pressing mechanism includes a first spring 401, which is located between the positioning rod 302 and the inner wall of the movable hole 303. A moving mechanism is provided at the top of the positioning rod 302. Through the elastic action of the first spring 401, the positioning rod 302 can be stably inserted into the annular groove 301 without being subjected to a large external force, thereby positioning the cover ring 202 in the groove 201. The annular arrangement of the annular groove 301 does not limit the installation angle of the cover ring 202 until the cover ring 202 is inserted into the groove 201.

[0037] The moving mechanism includes a slide groove 501 and a slider 502. The slide groove 501 is located at the top of the housing 101 and its interior is connected to the interior of the movable hole 303. The outer wall of the slider 502 is slidably connected to the inner wall of the slide groove 501. The slider 502 is fixedly connected to the top of the positioning rod 302. The slider 502 facilitates the movement of the positioning rod 302 at the top of the housing 101, thereby improving the ease of unlocking the positioning mechanism.

[0038] The pop-up mechanism includes a connecting ring 601 and a second spring 603. The connecting ring 601 is movably disposed inside the slot 201 and located below the cover ring 202.
