[0018] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0019] like Figure 1 , Figure 2 As shown, this embodiment provides a luminous step structure, including a stepped pad 1, a gravel layer 2 laid on the pad 1, a base layer 3 poured on the gravel layer 2, a supporting keel 4 set on the base layer 3, and a step plate 6 bonded and fixed on the supporting keel 4; the step plate 6 is provided with a plurality of light-transmitting holes 601, and a hanger is provided on the lower side of the step plate 6, the hanger including a plurality of hanging rods 7, the upper end of the hanging rods 7 is connected to the step plate 6, and the lower end is connected to a mounting plate 8 that runs through the entire length, and an LED light strip 15 is detachably connected to the mounting plate 8. The crushed stone layer 2 is made of basalt crushed stone with a particle size of 5-10mm and a thickness of 30-50mm, serving as a drainage and moisture-proof layer; the base layer 3 is 40mm thick C30 fine stone concrete with an embedded Φ6@200mm steel mesh; the light-transmitting holes 601 have a diameter of 10-15mm and a spacing of 50-80mm, arranged in a matrix or artistic pattern; the LED light strip 15 is a flexible light strip; the supporting keel 4 is a 40×40×3mm hot-dip galvanized square tube (GB / T-3091-2015) with a spacing of ≤600mm, fixed to the base layer 3 by M8 expansion bolts; the adhesive layer 5 uses modified silane sealant (such as Sika 291) with an adhesive strength ≥1.5MPa.

[0020] like Figure 3 , Figure 4As shown, the mounting plate 8 is provided with a sliding rail 9, and a first locking seat 10 for fixing the LED light strip 15 is fixedly arranged at one end of the sliding rail 9. A second locking seat 11 for fixing the LED light strip 15 is slidably connected in the sliding rail 9. A support seat 16 is further arranged at the end of the sliding rail 9 away from the first locking seat 10, and a reversing shaft 17 is arranged on the support seat 16. A traction rope 18 is further provided, one end of which is tied and fixed on the second locking seat 11, and the other end is wound around the reversing shaft 17 and tied on the first locking seat 10. The first locking seat 10 comprises a base, and a first stand 19 is arranged at each corner of the base. A first cover plate 20 is arranged at the top of the first stand 19, and a first locking bolt 21 is threadedly connected to the first cover plate 20. The second locking seat 11 comprises a sliding base slidably connected to the sliding rail 9. A second stand 12 is arranged at each corner of the sliding base. A second cover plate 13 is arranged at the top of the second stand 12, and a second locking bolt 14 is threadedly connected to the second cover plate 13. By tightening the first locking bolt 21 and the second locking bolt 14, the lower ends of the first locking bolt 21 and the second locking bolt 14 tightly abut against the LED light strip 15, thereby fixing the LED light strip 15.

[0021] When the LED light strip 15 is initially installed, one end of the traction rope 18 is tied and fixed on the second locking seat 11, and the other end is wound around the reversing shaft 17 and tied on the first locking seat 10. At this time, the second locking seat 11 is located at the end of the sliding rail 9 away from the first locking seat 10, and the LED light strip 15 is fixed by the first locking seat 10 and the second locking seat 11 (the first locking bolt 21 and the second locking bolt 14 tightly abut against the LED light strip 15). After the overall light-emitting step structure is installed, if the LED light strip 15 needs to be replaced during later use, the replacement can be performed from the side of the light-emitting step structure. Specifically, the replacement is performed from the side of the first locking seat 10. First, the traction rope 18 tied on the first locking seat 10 is untied, and then the first locking bolt 21 is loosened. The LED light strip 15 is pulled out from the side of the first locking seat 10. Since the other end of the LED light strip 15 is locked with the second locking seat 11, the LED light strip 15 drives the second locking seat 11 to slide towards the side close to the first locking seat 10. After the second locking seat 11 slides to the side close to the first locking seat 10, the second locking nut is loosened, and the LED light strip 15 is taken out. Then, one end of the new LED light strip 15 is locked in the second locking seat 11 by the second locking bolt 14. Then, the traction rope 18 is pulled, and under the action of the reversing shaft 17, the traction rope 18 drives the second locking seat 11 to slide away from the first locking seat 10. The second locking seat 11 synchronously drives the end of the new LED light strip 15 to move away from the first locking seat 10. After the second locking seat 11 slides to the end away from the first locking seat 10, the traction rope 18 is tied and fixed on the first locking seat 10. Then, the other end of the new LED light strip 15 is fixed on the first locking seat 10 by the first locking bolt 21. The replacement is simple and convenient, and the LED light strip 15 can be replaced from the side of the step structure without the need to remove the entire step plate 6.

[0022] The first locking bolt 21 is arranged through the first cover plate 20 and provided with a first pressing plate, and the second locking bolt 14 is arranged through the second cover plate 13 and provided with a second pressing plate; the first pressing plate and the second pressing plate can increase the contact area of the end of the first locking bolt 21 and the second locking bolt 14 with the LED lamp strip 15, thereby enhancing the friction and ensuring the fixing effect of the LED lamp strip 15.

[0023] The light-transmitting hole 601 is provided with a glass fiber light guide block, and the glass fiber light guide block is sealed and connected with the hole wall of the light-transmitting hole by hot melt glue; the hot melt glue can be polyurethane hot melt glue (PUR hot melt glue), EVA (ethylene-vinyl acetate) hot melt glue, modified silane hot melt glue (MS Polymer) and the like; the glass fiber light guide block sealed and connected in the light-transmitting hole 601 can prevent rainwater from entering the internal structure while not hindering the light transmission, thereby protecting the LED lamp strip 15 and the circuit and reducing the maintenance frequency; the LED lamp strip 15 has an IP67 or above waterproof level, cooperates with the hot melt sealing position, passes through a rigorous water flushing test (1L / min, 15 minutes without leakage), ensures the electrical safety in a humid environment, and simultaneously adopts 24V low-voltage power supply, thereby eliminating the risk of electric shock.

[0024] The utility model is suitable for artistic venue, commercial space and other high decorative scenes, and the light efficiency uniformity deviation is less than or equal to 10%, and the visual effect is better than that of traditional external embedded lamp strip; the LED lamp strip 15 is installed in a hanging bracket hidden mode, direct stress is completely avoided, and the problems of falling and deformation of traditional exposed lamp strip caused by treading are avoided; through the design of the unique slide rail 9 locking mechanism and traction rope 18, the lamp strip can be quickly replaced from the side, the single maintenance time is shortened to 15 minutes, the step plate 6 does not need to be removed, and the labor cost is reduced by more than 50%.

[0025] The utility model comprehensively solves the contradictory requirements of decorative, durability, maintainability and safety, and is especially suitable for public building spaces with large flow and high aesthetic requirements.

[0026] The above only describes the preferable embodiments of the utility model, and the utility model is not limited by the above, and equivalent changes made according to the content of the utility model specification and the drawings are included in the utility model right range.
