[0013] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0014] This invention boasts strong compressive strength: the stainless steel shell provides a robust external structure, while the internal flange structure and steel support columns enhance the overall compressive strength, enabling the floor tiles to withstand high pedestrian traffic and external pressure. It is suitable for public places with high pedestrian traffic, such as city squares and parks.

[0015] This utility model has high power generation efficiency: the photovoltaic module has a reasonable structural design, with steel support columns between the front and back tempered glass panels to avoid the solar cells, ensuring the effective light-irradiated area of ​​the solar cells. At the same time, the LED light strip is set below the solar cells, which can ensure the photoelectric conversion efficiency of the photovoltaic module.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] A multi-layered, pressure-resistant photovoltaic power generation floor tile, combined with Figures 1 to 2 As shown, the system includes a stainless steel housing 1 with an open top. A photovoltaic module 2 is installed at the top inside the stainless steel housing 1, converting light energy into electrical energy. LED light strips 6 are arranged around the perimeter of the stainless steel housing 1, positioned below the photovoltaic module 2 to avoid affecting its photoelectric conversion efficiency. A photovoltaic controller 3, an energy storage battery 4, and a step-sensing control module 5 are housed in the central cavity at the bottom of the stainless steel housing 1. The photovoltaic controller 3 is connected to the photovoltaic module 2, LED light strips 6, energy storage battery 4, and step-sensing control module 5, respectively. During the day, the photovoltaic controller 3 stores the electrical energy converted by the photovoltaic module 2 in the energy storage battery 4. At night, the photovoltaic controller 3 controls the energy storage battery 4 to release electrical energy. When the step-sensing control module 5 detects someone stepping on the photovoltaic power generation tiles, it controls the LED light strips 6 to light up, providing illumination.

[0024] The stainless steel housing 1 has a protective edge on its top, which is pressed against the top perimeter of the photovoltaic module 2 to protect it. Inside the stainless steel housing 1, there is a flange 11, which supports the photovoltaic module 2 and shields the LED light strip 6. This not only improves the compressive strength of the photovoltaic power generation paving tile but also reduces the heat from the LED light strip 6 being transferred to the photovoltaic module 2, thus minimizing its photoelectric conversion efficiency. The sidewalls of the stainless steel housing 1 have through holes for easy wiring, facilitating power supply to surrounding electrical facilities.

[0025] The photovoltaic module 2 is sealed to the stainless steel casing 1 with structural adhesive, thus providing waterproofing, gas protection, and dustproofing. The photovoltaic module 2 includes a front tempered glass panel 21, solar cells 22, and a back tempered glass panel 23 arranged sequentially from top to bottom. The solar cells 22 are glued to both the front and back tempered glass panels 21 and 23 respectively. A steel support column is provided between the front and back tempered glass panels 21 and 23, with the column avoiding the solar cells 22. The steel support column provides support, further improving the compressive strength of the photovoltaic power generation paving tiles. Simultaneously, the outer surface of the front tempered glass panel 21 has a textured surface that matches the existing paving tiles, creating a unified visual effect.

[0026] The LED light strip 6 is fixed in the stainless steel housing 1 by clips, and the LED beads of the LED light strip 6 are oriented towards the opposite side of the LED light strip 6 and emit light in a gradual manner to avoid direct glare. Specifically, the LED light strip 6 can be a silicone light strip or a stepless dimming light strip. The silicone light strip provides a more uniform and softer lighting effect and does not generate heat, thus not affecting the safety of battery power generation; the stepless dimming light strip can change to multiple colors, has a uniform edge light emission effect, and is highly interactive and visually appealing.

[0027] The step-sensing control module 5 includes an induction coil 51 and a detection circuit 52. The induction coil 51 is embedded in the bottom of the stainless steel housing. The detection circuit 52 is connected between the induction coil 51 and the photovoltaic controller 3. When someone steps on the photovoltaic power generation floor tile, it causes a change in the magnetic field around the induction coil 51. The induced electromotive force or induced current generated by the induction coil 51 is detected by the detection circuit 52. The detection circuit amplifies and filters this weak signal and then converts it into a signal that the photovoltaic controller 3 can recognize, such as a digital signal (high level or low level). The photovoltaic controller 3 then controls the LED light strip 6 to light up. When the person leaves, the magnetic field returns to normal and the light goes out.

[0028] In use, during the day, the photovoltaic module 2 continuously converts solar energy into electrical energy and stores it in the energy storage battery 4. At this time, the LED light strip 6 remains off regardless of whether there is any stepping activity.

[0029] At night, the photovoltaic controller 3 enters standby mode according to a preset time program, ready to receive signals from the step-sensing control module 5. Once someone steps on the floor tile, the step-sensing control module 5 triggers a signal to the photovoltaic controller 3, which then controls the LED light strip 6 to emit light, providing illumination. When the person leaves, the step-sensing control module 5 no longer generates a trigger signal, and the photovoltaic controller 3, based on a set delay time or other logical judgment, cuts off the power supply to the LED light strip 6, turning it off.

[0030] Alternatively, a light sensor can be set to collect the intensity of light. When the light is weak, the photovoltaic controller 3 enters standby mode and prepares to receive the signal from the step-sensing control module 5.
