[0018] When the utility model is used in a specific way,

[0019] The lens 1 is pointed at the direction of sunlight to focus the sunlight. The focused sunlight enters the optical fiber bundle 2, propagates and radiates from the end of the optical fiber bundle 2, and can be used as a lighting source. The direction of the end of the optical fiber bundle 2 is adjusted using an angle adjustment device to make the irradiation angle more suitable for easy use.

[0020] When the angle adjustment device is in use, the specific adjustment method is: fix the connecting frame 4 at an appropriate height on the first bracket 3, and fix the first wiring harness sleeve 6 at the end of the optical fiber bundle 2, and then use the first connecting rod 5 to connect the first wiring harness sleeve 6 to the connecting frame 4, and finally lock the first connecting rod 5 with a screw to fix its connection angle, thereby achieving the fixation of the direction of the end of the optical fiber bundle 2.
