the first embodiment is as follows:

in the first embodiment shown in fig. 1 and 2, the LED light-emitting floor tile includes a bottom frame 1 fixed on a foundation, wherein a layer of memory sponge 2 is disposed on the frame-shaped upper surface of the peripheral wall of the bottom frame 1; a cover plate 3 made of ground glass covers the memory sponge 2; a micro mirror surface ball 4 is fixed downwards at the center of the cover plate 3; the circumference equipartition has LED light beam lamp 5 on the internal perisporium of underframe 1, LED light beam lamp 5 produces the width and equals diameter, the thickness of miniature mirror surface ball 4 are less than 1 mm's linear light beam to make single beam linear light beam by miniature mirror surface ball 4 reflection back, can form the annular light shadow of semicircle on the apron, the linear light beam of the LED light beam lamp 5 production of a plurality of circumference equipartitions, after miniature mirror surface ball 4 reflection, can synthesize a complete aureole on apron 3.

In a natural state, when the cover plate 3 is at an upper limit position, the linear light beam irradiates the middle lower part of the micro-mirror-surface ball 4; at this time, the linear light flux is reflected by the micro mirror surface balls 4 and then irradiated to the lower side of the cover plate 3, so that no shadow is formed on the cover plate 3, and a diffuse reflection layer may be provided on the inner side of the peripheral wall of the bottom frame 1 in order to still contribute light to the cover plate 3, thereby uniformly lighting the cover plate 3 by the reflected linear light flux by diffuse reflection.

When the cover plate 3 is stepped down to the lower limit position, the linear light beam irradiates the top of the micro-mirror sphere 4.

In this embodiment, the lower surface of the cover plate 3 is further provided with a vibration delay switch 51 coupled to the LED light beam lamp 5, and the LED light beam lamp 5 is turned on for a period of time only when the vibration delay switch 51 vibrates, so as to save electric energy of the LED light beam lamp 5. An LED array lamp 6 facing upwards to the cover plate 3 is further arranged in the bottom frame 1, and the color of the LED array lamp 6 is different from that of the LED beam lamp 5; to provide overall background illumination for the cover plate 3; the LED array lamp 6 is a white light lamp or a yellow light lamp, and the LED beam lamp 5 is a red light lamp or a green light lamp.

After the LED light-emitting floor tile is trodden, the cover plate 3 sinks to the lower limit position, at the moment, the linear light beams irradiate the top of the micro mirror surface ball 4, after a human body walks through the floor tile, the cover plate 3 slowly rises under the slow rebound characteristic of the memory sponge 2, the linear light beams gradually move downwards from the top of the micro mirror surface ball 4 to the middle lower part, in the process, the linear light beams are reflected by the micro mirror surface ball 4, the reflected light firstly forms a light ring at the center of the cover plate 3, and as shown in figure 1, the dotted line is the track line of the linear light beams; with the slow upward movement of the micro-mirror sphere 4, the light ring slowly expands from the center of the cover plate 3 to the periphery of the cover plate 3, as shown in fig. 2; the light ring disappears until the linear light beam moves to the middle lower part of the micro mirror surface ball 4; thereby forming an annular dynamic ripple effect spreading from the center to the periphery of the cover plate 3 and having strong interactive entertainment.

Example two:

for the second embodiment shown in fig. 3, it is different from the first embodiment in that guide posts 31 are uniformly distributed circumferentially below the cover plate 3, and the guide posts 31 are matched with slide ways opened in the peripheral wall of the bottom frame 1; so as to strictly restrict the movement of the cover plate 3 in the vertical direction and prevent the cover plate from tilting, thereby forming a regular circular ring on the cover plate 3 after the linear light beam is reflected on the micro mirror surface ball 4.

A piezoelectric ceramic block 32 is arranged in the slide way, the guide column 31 and the cover plate 3 are limited by the piezoelectric ceramic block 32, namely, when the guide column 31 props against the piezoelectric ceramic block 32, the cover plate 3 reaches a lower limit position.
