[0026] As the instruction manual Figures 1-4 As shown:

[0027] An LED lamp light guide structure includes: an LED lamp 200, a light guide column 110, and a concave mirror surface 210; the LED lamp 200 is arranged in the concave mirror surface 210, and the concave mirror surface 210 covers the LED lamp 200; the LED lamp 200 and the concave mirror surface 210 are arranged in the light guide column 110.

[0028] A working principle of an LED lamp light guide structure: the concave mirror surface 210 is a light-transmitting structure, the LED lamp 200 emits light, and the light is emitted through the concave mirror surface 210. The emitted light includes direct light 202 and reflected light 204. The direct light 202 is directly emitted from the light outlet 111 of the light guide column 110, and the reflected light 204 is arranged on the inner wall of the light guide column 110 and is reflected multiple times before being emitted from the light outlet 111, so that the light guide column 110 reflects and gathers the emitted light and then emits it through the light outlet 111.

[0029] In the present embodiment, an LED lamp light guide structure transmits the light emitted by the LED lamp through a concave mirror surface, thereby expanding the emission angle of the LED light. The light guide column reflects and gathers the transmitted light and then emits it, thereby increasing the brightness of the output light, making the light emitted from the light outlet more concentrated, and reducing the product production and use costs.

[0030] Specifically, the inner wall of the light guide column side wall 120 is smooth and provided with a reflective layer to avoid energy loss during the light guiding process.

[0031] Specifically, the concave mirror 210 covers the LED lamp 200 and is disposed at the bottom end of the light guide column 110, and the LED lamp 200 is disposed on the top surface of the printed circuit board (PCB) 300. The LED lamp 200 is electrically connected to the printed circuit board 300, and the power supply and control of the LED lamp 200 are realized through the printed circuit board 300.

[0032] Specifically, the printed circuit board 300 is one or more of a single-sided board, a double-sided board, a multi-layer board, a flexible board, a rigid-flexible board, an aluminum substrate, a ceramic substrate, a high-frequency board, a green PCB, a blind buried via board, a high-density interconnect board, a package substrate, etc.

[0033] Specifically, an LED lamp light guide structure further includes a reflective coating 310. The bottom surface of the reflective coating 310 is disposed on the top surface of the printed circuit board (PCB) 300, and the LED lamp 200 is disposed on the top surface of the reflective coating 310. After part of the light emitted by the LED lamp 200 is reflected by the concave mirror 210 to the reflective coating 310, it is reflected into the interior of the light guide column 110 and then emitted from the light outlet 111.

[0034] Specifically, a foam 320 is disposed around the LED lamp 200. The foam 320 realizes heat insulation between the LED lamp 200 and the surrounding environment, avoiding the influence of too high temperature on the light-emitting performance of the LED lamp 200. The foam also has the effects of support, shock absorption, dust prevention, waterproofing, moisture-proofing, and anti-static.

[0035] Specifically, the cross-section of the light guide column 110 is various shapes such as circular, square, rectangular, rhombic, triangular, pentagonal, hexagonal, etc. Users can select the shape of the LED lamp according to their own needs, improving the aesthetics and design sense of the LED lamp, making the LED lamp more iconic.

[0036] Specifically, the concave mirror 210 is made of a transparent or semi-transparent material, including a combination of one or more materials such as light-transmitting glass, light-transmitting plastic, transparent resin, transparent crystal, transparent ceramic, and transparent concrete.

[0037] Specifically, a light guide lamp hole 101 is provided on the electronic device housing 100, and the LED lamp 200, the light guide column 110, and the concave mirror 210 of the LED lamp light guide structure are disposed in the light guide lamp hole 101.
