[0013] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0014] In this invention, during the use of the LED lamp, the heat generated by the LED ring during operation can be transported to the outside of the LED lamp through the air inlet, collection shell and air outlet pipe, thereby achieving heat dissipation treatment of the LED ring, extending the service life of the LED ring and improving its practicality. Furthermore, the fluorescent film fixedly connected to the lower surface of the lamp cover, together with the phosphor coating on the LED beads inside the LED ring, achieves a double-layer phosphor effect, which can effectively fold the blue light emitted by the LED beads and give the LED a more beautiful warm color, achieving a more natural color effect. In this invention, rotating the inner and outer knobs respectively causes the side limiting plate to engage with the support ring, clamping the side limiting plate and support ring into the pre-set holes in the ceiling, thus completing the installation and fixation of the LED light. The outer knob then drives the side support plate to support both sides of the LED light ring, achieving fixation and installation of the LED light ring. This invention facilitates both LED light and LED light ring installation, optimizing the installation process and making it easier to replace the LED light ring, thereby improving the practicality of the LED light. Furthermore, since both the inner and outer knobs are installed within the installation ring, rotating them allows for two different installation effects, making the installation and replacement of LED lights and LED beads more convenient and faster. In this invention, when the outer knob drives the turntable to rotate, it drives the limit push block to link with the second connecting rod, pushing the anti-blue light film to move to both sides above the LED beads. The anti-blue light film can refract and eliminate the blue light emitted by the LED bead crystal, making the LED light safer and effectively protecting the user's eyesight. In addition, the outer knob can also drive the side support plate to install and fix the LED beads. Rotating at one point can not only perform anti-blue light treatment on the LED light, but also facilitate the installation of the LED beads, enhance the linkage of the LED light structure, and thus improve the practicality of the LED light.

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0030] Currently, there are no white LED lights. Most LED lights are formed by combining blue light and yellow phosphor. During use, the LED chip emits blue light. If this blue light is not processed, and since it is invisible to the human eye, prolonged use of LED lights can cause eye damage and affect the user's vision. Furthermore, because the chip and phosphor are bonded together with a gel, prolonged use of LED lights can lead to poor heat dissipation and easy damage to the LED beads. When a bead is damaged, it needs to be replaced, a process that requires tools and is complex and cumbersome, thus reducing the practicality of LED lights.

[0031] Therefore, the present invention aims at least in that rotating the outer knob 313 can push the two side support plates 307 to move to both sides. The side support plates 307 can support and press the LED ring 400 against both sides, thus fixing the LED ring 400 in place. Simultaneously, it will also trigger the LED heat dissipation assembly 200 to move the anti-blue light film 204 to the upper surface of the LED ring 400. The anti-blue light film 204 can refract and eliminate the blue light emitted by the crystal, making the LED lamp safer and effectively protecting the user's eyesight. By rotating the turntable 302, the simultaneous two-in-one effect of anti-blue light and fixing the LED beads is achieved, enhancing the LED's performance. The linkage of the lights allows the inner knob 317 to rotate, which in turn moves the side limiting plate 309 toward the support ring 101, thereby clamping it into the preset hole in the ceiling. This facilitates the installation of the LED light and the LED ring 400, optimizing the installation process and making it easier to replace the LED ring 400, thus improving the practicality of the LED light. At the same time, the drive motor 209 drives the conveying fan blade 211 to rotate, which can transfer the heat emitted by the LED beads of the LED ring 400 to the outside of the LED light, achieving heat dissipation treatment for the LED ring 400, extending the service life of the LED ring 400 and improving its practicality.

[0032] Example, according to Figures 1-12 ,like Figures 1-3 As shown in the figure, an LED lamp with double-layer phosphor provided by the present invention includes an outer support member 100, in which a lamp bead mounting assembly 300 is installed. An LED lamp ring 400 is mounted on the outer support member 100 through the lamp bead mounting assembly 300. When installing the LED lamp ring 400, the lamp bead mounting assembly 300 can also install the device in a preset hole in the ceiling. Lamp bead heat dissipation assemblies 200 are also installed on both sides inside the outer support member 100. The lamp bead heat dissipation assembly 200 and the lamp bead mounting assembly 300 are driven together. During the heat dissipation process of the LED lamp ring 400, the lamp bead heat dissipation assembly 200 can also perform blue light protection treatment on the LED lamp ring 400.

[0033] like Figure 11 As shown, the LED heat dissipation assembly 200 includes a collection shell 201. An air inlet 205 is provided on one side of the collection shell 201. A drive motor 209 is fixedly connected to one side of the inner wall of the air inlet 205. A rotating shaft 210 is fixedly connected to one end of the drive motor 209. Several evenly distributed conveying fan blades 211 are fixedly connected to the middle of the surface of the rotating shaft 210.

[0034] like Figure 6 As shown, the LED bead mounting assembly 300 includes a turntable 302. Mounting members 303 are rotatably mounted on both sides of the upper surface of the turntable 302. A transmission plate 304 is rotatably mounted on each mounting member 303. A rotating member 310 is provided at one end of the transmission plate 304. A fixing plate 305 is fixedly connected to one side of the rotating member 310. A side support plate 307 is fixedly connected to one end of the fixing plate 305.

[0035] In this embodiment, the drive motor 209 is started to drive the conveyor blades 211 to rotate around the shaft 210. The conveyor blades 211 can transport the heat emitted by the LED beads of the LED ring 400 through the air inlet 205, the collection shell 201 and the air outlet 202 to the outside of the LED, thereby achieving heat dissipation treatment for the LED ring 400, extending the service life of the LED ring 400 and improving its practicality. Rotating the outer knob 313 can drive the turntable 302 to rotate within the mounting ring 104. The two sides of the turntable 302 are connected to the transmission plate 304 through the mounting parts 303. The transmission plate 304 is connected to the fixed plate 305 and the side support plate 307 through the rotating parts 310, which can push the two side support plates 307 to move outward. After being limited by the slide rail 311 and the L-shaped support rod 306, the side support plates 307 can move horizontally, realizing the installation and fixation of the LED ring 400, which facilitates the replacement of the LED ring 400.

[0036] like Figure 5 As shown, the external support component 100 includes a support ring 101. A snap-fit ​​ring 102 is fixedly connected to the upper surface of the support ring 101. Four evenly distributed first connecting rods 103 are fixedly connected to the inner side of the support ring 101. An installation ring 104 is fixedly connected to the center of each first connecting rod 103. A support block 105 is fixedly connected to the upper surface of each first connecting rod 103. A lampshade 107 is connected to the support ring 101 through the snap-fit ​​ring 102. A fluorescent film 108 is fixedly connected to the inner wall of the lampshade 107. A third sliding groove 110 is provided on the inner surface of the support ring 101. Two opposing movable blocks 109 are installed in the third sliding groove 110. A limit rod 106 is fixedly connected to the inner side of each movable block 109.

[0037] In this embodiment, a fluorescent film 108 is fixedly connected to the lower surface of the lampshade 107, and combined with the phosphor coating on the LED beads inside the LED ring 400, a double-layer phosphor effect is achieved. This effectively folds the blue light emitted by the LED beads and gives the LED a more aesthetically pleasing warm color, achieving a color closer to nature.

[0038] like Figures 9-12 As shown, the collecting shell 201 is fixedly connected to two ends of the side of the collecting shell 201 away from the air inlet 205, and mounting grooves 203 are provided. Air outlet pipes 202 are fixedly connected to both sides of the lower surface of the collecting shell 201. A mounting rod 214 is provided in the mounting groove 203, and a connecting bracket 213 is fixedly connected to the lower end of the mounting rod 214. A second connecting rod 216 is fixedly connected between the connecting brackets 213. A central shaft 212 is fixedly connected at the connection between the mounting rod 214 and the connecting bracket 213. The central shaft 212 is rotatably mounted in the mounting groove 203. An air outlet 207 is provided at the lower end of the air outlet pipe 202. The interior of the collecting shell 201 is configured as a collecting chamber 208. A sliding door 207 is provided on one side of the mounting rod 214. The groove 220 has a limiting rod 219 installed inside it. One end of the limiting rod 219 is fixedly connected to a limiting bracket 215. One end of the limiting bracket 215 is fixedly connected to an anti-blue light film 204, which is located above the LED light ring 400. A limiting plate 221 is installed on the limiting bracket 215 and is fixedly connected to the upper surface of the collecting shell 201. A limiting push block 218 is movably sleeved on the second connecting rod 216. An extension rod 222 is fixedly connected to one side of the limiting push block 218. A connecting sheet metal 217 is movably installed on the extension rod 222. A side fixing seat 206 is rotatably installed on one end of the connecting sheet metal 217 and is fixedly connected to both sides of the turntable 302.

[0039] In this embodiment, when the turntable 302 is rotated, extension rods 222 are installed on both sides of the turntable 302 via connecting sheet metal 217. One end of the extension rod 222 is fixedly connected to a limiting push block 218, which is movably sleeved on the second connecting rod 216. The second connecting rod 216 is inclined, which can drive the connecting bracket 213 and the mounting rod 214 to rotate around the central axis 212. Since a first sliding groove 220 is provided on one side of the mounting rod 214, a limiting rod 219 is installed in the first sliding groove 220 to limit the rotation. One end of the rod 219 is fixedly connected to a limiting bracket 215. A limiting plate 221 is installed on the outside of the limiting bracket 215. The limiting plate 221 is fixedly connected to the upper surface of the collecting shell 201. After being limited by the limiting plate 221, the limiting bracket 215 can move horizontally along the limiting plate 221, which can drive the anti-blue light film 204 to move to the upper surface of the LED light ring 400. The anti-blue light film 204 can refract and eliminate the blue light emitted by the crystal, making the LED light safer and effectively protecting the user's eyesight.

[0040] like Figures 6-8 As shown, external knobs 313 are fixedly connected to both sides of the lower surface of the turntable 302. The external knobs 313 are rotatably mounted within the mounting ring 104. A slide rail 311 is fixedly connected to the lower surface of each fixed plate 305. An L-shaped support rod 306 is movably mounted within the slide rail 311 and is fixedly connected to the inner wall of the support ring 101. A bearing 315 is fixedly connected between the lower surface of the turntable 302 and the external knobs 313. A fixing block 314 is fixedly connected within the bearing 315. A rotating screw 316 is fixedly connected to the lower end of the fixing block 314. An internal knob 317 is fixedly connected to the lower end of the rotating screw 316. A threaded sleeve 318 is engaged in the middle of the rotating screw 316. A lifting plate 319 is provided in the middle of the threaded sleeve 318. The lifting plate 319 is U-shaped. The lifting plate 319 is disposed between two external knobs 313. Slider 320 is fixedly connected to the four corners of the outer side of the lifting plate 319. The slider 320 is installed in the second slide groove 312. The second slide groove 312 is disposed at the edge of the external knobs 313. Limit sleeves 321 are provided on both sides of the lifting plate 319. A movable rod 322 is movably installed in each limit sleeve 321. A telescopic sleeve rod 323 is movably installed at one end of each movable rod 322. A side limit plate 309 is fixedly connected to one end of the telescopic sleeve rod 323. The side limit plate 309 is located on both sides below the support ring 101. Side fixing blocks 301 are fixedly connected to both sides of one end of the telescopic sleeve rod 323. A limit oblique hole 308 is provided in the middle of each side fixing block 301. A limit oblique rod 106 is provided in the limit oblique hole 308.

[0041] In this embodiment, rotating the inner knob 317 drives the rotating screw 316 to rotate, and the rotating screw 316 drives the lifting plate 319 to rise and fall. The lifting plate 319 is installed in the second slide groove 312 via the slider 320. When the lifting plate 319 rises, the movable rod 322 is movably installed on the limiting sleeves 321 on both sides of the lifting plate 319. The movable rod 322 is movably fitted with a telescopic sleeve 323. The telescopic sleeve 323 is fixedly connected to both sides of the telescopic sleeve 323. The side fixing blocks 301 are fitted onto the limiting inclined holes 308. On the limiting inclined rod 106, when the lifting plate 319 drives the movable rod 322 and the telescopic sleeve rod 323 to rise and fall, the telescopic sleeve rod 323 can also extend and retract along the movable rod 322 after being limited by the limiting inclined rod 106, thereby driving the side limiting plate 309 to move towards the support ring 101, and then clamping it into the preset hole in the ceiling, so as to achieve the installation of LED lights and facilitate the installation of LED light ring 400, optimize the installation steps of LED lights and facilitate the replacement of LED light ring 400, thereby improving the practicality of the LED light.
