[0028] Please refer to the attached document. Figures 1-7 In this embodiment, the main body 10 of the seating chair is used to place the seat, tabletop, desktop, or sofa of an external chair, so that the main body 10 of the seating chair can stably place the seat, tabletop, desktop, or sofa of an external chair. The main body 10 of the seating chair includes a first support part 11 and a second support part 12. The second support part 12 is integrally connected to the first support part 11, which improves the connection strength between the second support part 12 and the first support part 11 and ensures the connection stability between the second support part 12 and the first support part 11. The first support part 11 is connected to a seat cushion 111, which is used for the user's buttocks to press against and to flexibly deform under pressure. This allows the seat cushion 111 to flexibly deform and wrap around the user's buttocks, thereby facilitating the user's buttocks to make flexible contact with the first support part 11 through the seat cushion 111, improving the user's buttocks comfort. The second support portion 12 is used to support the user's waist. The second support portion 12 extends upward in a fluid shape so that the second support portion 12 and the first support portion 11 form an L-shape. The contours of the second support portion 12 and the first support portion 11 are adapted to the contours of the user's buttocks and waist when in a sitting position.

[0029] The connector 20 is connected to the second support portion 12 and is located on the side of the second support portion 12 facing the user's waist. The connector 20 is made of plastic, which is lightweight, reducing the overall weight of the red light component 100 and facilitating the repositioning of the red light component 100. The connector 20 can be adjusted relative to the second support portion 12, ensuring a comfortable fit between the connector 20 and the user's waist or back. The connector 20 is provided with a receiving groove 20a, which serves as the internal space of the connector 20.

[0030] The red light module 30 is disposed inside the connector 20 and is detachably connected to the connector 20, allowing it to be connected to or detached from the connector 20. Specifically, the red light module 30 is detachably connected to the connector 20 via bolts. The red light module 30 is stationary relative to the connector 20, but its position changes with the position of the connector 20. The red light module 30 is housed in a receiving groove 20a, making full use of the space in the receiving groove 20a. The red light module 30 has multiple LED beads 31, which are arranged along the length of the connector 20 and converge at the center of the connector 20. The multiple LED beads 31 output red light when in operation, allowing the user's waist or back to absorb the red light. The red light promotes blood circulation and skin cell metabolism in the user's waist or back, accelerates wound healing, and stimulates collagen production, which helps with anti-aging. The red light heating can dilate microvessels and increase blood and oxygen supply.

[0031] A flexible jacket 40 is disposed on the outside of the connector 20. The flexible jacket 40 is detachably fitted onto the connector 20 so that the flexible jacket 40 can be connected to or detached from the connector 20. The flexible jacket 40 wraps around the connector 20 and the red light module 30. The red light module 30 is located between the connector 20 and the flexible jacket 40. The red light output by multiple LEDs 31 passes through the flexible jacket 40 and is used to illuminate the user's waist or back, so that the connector 20 and the flexible jacket 40 can protect the red light module 30, prevent the red light module 30 from being exposed to the external environment and subjected to direct physical impact, ensure the stability of the red light module 30 of the red light assembly 100, and improve the service life of the red light module 30 of the red light assembly 100.

[0032] Please refer to the attached document. Figures 1-6In this embodiment, the red light module 30 further includes a first circuit board 32 and a lens 33. The first circuit board 32 is detachably connected to the inner wall of the receiving groove 20a and is located within the receiving groove 20a, so that the first circuit board 32 can be connected to or detached from the receiving groove 20a. This facilitates the detachable connection of the red light module 30 relative to the connecting seat 20 via the first circuit board 32. Specifically, the first circuit board 32 is detachably connected to the inner wall of the receiving groove 20a via bolts. The first circuit board 32 is arranged along the length of the connecting seat 20 and is stationary relative to the connecting seat 20. Multiple LED beads 31 are integrated on the same first circuit board 32 and face forward toward the part of the flexible outer sleeve 40 for the user's waist to contact, so that the first circuit board 32 outputs signals to the multiple LED beads 31 and outputs red light toward the flexible outer sleeve 40. The lens 33 is sleeved on the corresponding LED bead 31, so that the lens 33 protects the LED bead 31 and prevents damage to the LED bead 31.

[0033] The flexible jacket 40 has a light-transmitting hole 40a in the part for contact with the user's waist. Red light emitted by multiple LED beads 31 passes through the light-transmitting hole 40a and illuminates the user's waist or back. This allows the red light emitted by the LED beads 31 to pass through the space of the flexible jacket 40a and extend to the user's waist or back.

[0034] Please refer to the attached document. Figure 1 and 6 In this embodiment, multiple light-transmitting holes 40a are arranged opposite to the corresponding LED beads 31. These holes connect the receiving groove 20a and the external environment along the front-to-back direction and are exposed to the corresponding LED beads 31. The arrangement of multiple light-transmitting holes 40a ensures that multiple LED beads 31 simultaneously illuminate the user's waist or back, thus increasing the range of red light output by the red light module 30. The lens 33 is located outside the LED beads 31, providing external protection. The red light output by the LED beads 31 is transmitted through the lens 33 to the corresponding light-transmitting hole 40a, ensuring the effectiveness of the red light output while protecting the LED beads 31 and extending their lifespan.
