Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or position relationship shown in the drawings, and are only for convenience of description and simplification of the present invention, but do not indicate or imply that the device or element of the present invention must have a specific orientation, and thus, should not be construed as limiting the present invention.

Example one

As shown in fig. 1, a light guide ring 100, the light guide ring 100 includes an LED lamp bead 110, an annular light guide body 120, and 4 light guide sheets 130 connected end to end and extending outward from a side surface of the annular light guide body 120, the light guide sheet 130 is a gradually changing arc shape gradually widening from a starting end 131 to a tail end 132, a positioning column 140 is disposed at a bottom of the light guide sheet 130, and the LED lamp bead 110 is fixed on an end surface of the tail end 132 of the light guide sheet 130.
