[0037] The working principle of this utility model:

[0038] First, the shell 1 is pre-buried and installed, and then the light guide tube 2 is placed in the shell 1 for installation, and then the light guide ring 3 is placed on the support 7 at the top of the shell 1, and the light guide ring 3 is located at the top of the light guide tube 2 in the shell 1, and then the limiting column 24 on the outside of the collecting component 6 is inserted into the limiting groove 25 on the inside of the light guide ring 3, and then the anti-falling steel mesh 5 is placed on the top of the light guide ring 3. At this time, the positioning column 27 is embedded in the positioning groove 28 to limit and fix the anti-falling steel mesh 5, and then the lighting cover 4 is placed on the top of the light guide ring 3. Then, the gasket 401 is sleeved on the outside of the light cover 4 and then screwed and fixed to the top of the shell 1, so that the gasket 401 presses and fixes the light cover 4, and at the same time, the fixing column 16 squeezes and pushes the lock block 22, and then the lock block 22 squeezes the second spring 20 through the driving block 21. When the lock block 22 is pushed away by the thrust, the second spring 20 squeezes the driving block 21, and then the driving block 21 drives the lock block 22 to be embedded in the lock groove 23 to lock and fix the fixing column 16, thereby fixing the light cover 4. The light hood 4 collects sunlight and transmits it through the light guide ring 3 and the light guide tube 2. The light guide tube 2 transmits the light source through the diffuser 201. When the light hood 4 is stepped on, the debris of the light hood 4 falls into the collecting member 6. At the same time, the anti-falling steel mesh 5 is forced to buffer and support. At the same time, the anti-falling steel mesh 5 squeezes the light guide tube 2 downward through the light guide ring 3. At this time, the light guide tube 2 squeezes the support plate 10 at the bottom of the fixing frame 11 through the support ring 12, and then the support plate 10 drives the sliding block 9 to move in the fixed frame. The fixed rod 13 slides on the outside, and the first spring 14 squeezes and supports the sliding block 9, and the shock absorber 15 buffers and dampens the dynamic potential energy of the sliding block 9. Since the force is mutual, the shock absorber 15 and the first spring 14 push and support the sliding block 9, so that the light guide tube 2 supports the anti-fall steel net 5 upward through the light guide ring 3, and the third spring 30 supports the support member 7, and then the support member 7 supports the light guide ring 3, so as to prevent people from stepping on the light cover 4 and falling and being injured.
