Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0034] Please see Figure 1-2 This utility model provides a technical solution: a sloping ceiling lighting structure for ancient buildings, comprising:

[0035] The central pointed ceiling includes a first inclined plate 1 and a second inclined plate 2. The upper ends of the first inclined plate 1 and the second inclined plate 2 are connected by a connecting frame 3. The top of the first inclined plate 1 is raised upward to set a first enclosure 4.

[0036] Edge ceiling 5, which is fixed at the edge of the central pointed ceiling, with an inner side extending upwardly upside second enclosure 6;

[0037] The first light fixture 7 is installed on the surface of the first inclined plate 1, the second inclined plate 2, and the edge ceiling 5;

[0038] The second light fixture 8 is concealed inside the first enclosure 4 and the second enclosure 6;

[0039] The central pointed ceiling and the edge ceiling 5 are suspended from the top beam 110 inside the pointed roof 100 by the first hanger 9. The bottom of the first hanger 9 is provided with a keel connector 10. The top surfaces of the first inclined plate 1, the second inclined plate 2, and the edge ceiling 5 are provided with mutually perpendicular and staggered reinforcing keels 11 and covering keels 12. The keel connector 10 is connected to the reinforcing keel 11 and the covering keel 12.

[0040] The top beams 110 are arranged perpendicularly to each other and staggered in layers within the pointed roof 100. Reinforcing steel frames 13, made of angle steel or square tubing, are installed at the joints of the upper and lower layers of top beams 110. The top beams 110 are filled with an epoxy resin layer. Carbon fiber cloth is also used to reinforce the top beams 110. The sloping facade, pointed ceiling, and lighting structure of this ancient building are constructed on the basis of the wooden components of the ancient building, requiring structural reinforcement of the original components. Specifically, the critical load-bearing parts are reinforced with reinforcing steel frames 13, while non-critical load-bearing parts are reinforced with epoxy resin layers and carbon fiber cloth to repair cracks and other defects on the surface of the original components, thereby improving structural stability while preserving the traditional architectural form.

[0041] A triangular support plate 14 is fixed between the first inclined plate 1 and the second inclined plate 2. This further improves the structural strength of the central pointed ceiling and provides local shading to ensure uniform lighting.

[0042] The top of the first inclined plate 1 is lower than the top of the second inclined plate 2. The connecting frame 3 has a C-shaped structure with its opening facing the second inclined plate 2. Its upper end connects to the second inclined plate 2, and its lower end is positioned inside the first enclosure 4. This improves the structural strength at the joint between the tops of the first inclined plate 1 and the second inclined plate 2, and avoids structural damage caused by mutual compression when directly joined.

[0043] A second hanger 15 is also provided on the top beam 110. An L-shaped connecting plate 16 is provided at the lower end of the second hanger 15. The right-angled edge of the L-shaped connecting plate 16 is attached to the vertical plate surface of the central pointed ceiling and the edge ceiling 5 and fixed with screws to further improve the assembly strength of the tiered or stepped ceiling structure.

[0044] The wires 17 leading from the first lamp 7 and the second lamp 8 are threaded into an iron pipe. The iron pipe is positioned on the flame-retardant wire troughs pre-embedded in the surface of the central pointed ceiling and the edge ceiling 5. The joints of the wires 17 and the iron pipes are sealed with fireproof putty. The lamps are installed and controlled using flame-retardant wire troughs and a wireless light control system, avoiding damage to the original wooden components of the ancient building, such as the pointed roof 100 and the top beam 110, caused by exposed wiring.

[0045] The assembly process of a sloping ceiling lighting structure for ancient buildings in this embodiment includes:

[0046] Preliminary measures: Erect scaffolding for protection. First, erect scaffolding and hang dustproof netting and fall protection netting, without damaging the original wooden structure.

[0047] Demolishing the old roof: Use a small electric hammer and a hand pry bar to dismantle from top to bottom. For rotten wood, analyze the load-bearing structure. If it is not a critical load-bearing part, it can be reinforced with epoxy resin and carbon fiber cloth. If it is a critical load-bearing part, it needs to be reinforced and fixed with a steel frame. Fill the cracks with transparent glue (epoxy resin) and paint the surface with an old color.

[0048] Concealed wiring: The wires are run through iron pipes and stuffed into the gaps in the wood, and the joints are sealed with fireproof putty.

[0049] Laying out the lines: Since the lighting fixtures primarily serve the dining table, the overall baseline cannot be based on the building's centerline. A centerline needs to be determined on-site based on the dining table's positioning line, and then a level is used to lay out the baseline. Using this center point as the center, a circle of the corresponding radius is drawn based on the simulation results, and points are divided at equal intervals. These points are then mapped onto the ceiling using a laser level. Next, a comprehensive analysis of the relationship between the lighting fixtures, the overall lighting points, and the joist arrangement is conducted to finalize the positioning plan. Two symmetrical light holes are pre-drilled to check if they meet the lighting requirements. If they do, subsequent construction can proceed.

[0050] Lighting fixture positioning: Due to the inconsistent height of the left and right sloping roofs, the shape of the light spots projected by each lighting fixture is different. Therefore, the positioning of the lighting fixtures must be optimized to prevent glare from direct light on diners below.

[0051] Dimming: The lighting primarily illuminates the dining area. The specific area needs to be defined based on the table's positioning line, and then the direction and angle of the lights are adjusted to ensure both the design effect and a comfortable dining environment are achieved. Specifically, for the special structure of the sloping ceiling, calculations are used to optimize the elliptical light spots projected by conventional spotlights into circular light domains, with the spot diameter error controlled within ±10cm. This ensures that the illumination boundary of the dining area (diameter 1.8-2.4m) is precisely controlled within the set range. Deep application of simulation technology: Based on the Autodesk simulation system, simulations are established including parameters such as ceiling slope, light fixture projection angle, and spatial reflectivity, achieving full-process digital management of "design-simulation-construction". The specific implementation process is as follows: Three-dimensional data acquisition: key dimensions are measured using a laser rangefinder. The lowest point elevation of the suspended ceiling is 2.8m, the highest point elevation is 3.6m, and the horizontal span of the sloping surface is 4.2m. Lighting fixture parameter modeling: a lighting fixture database is established. Key parameters include: beam angle: 24° / 36°, adjustable color temperature: 2700K±150K, color rendering index: Ra≥90, power: 12W / 18W. Dual-mode intelligent spot placement simulation: CAD simulation is used to set constraints. The light spot coverage diameter is: dining table diameter + 1.2m; illuminance gradient: center area ≥300lx, transition area ≥150lx; glare index: UGR<19. The construction verification system adopts a three-stage control of "simulation-implementation-testing": ① Simulate the suspended ceiling model at a 1:10 scale to verify the light spot morphology; ② Pre-embed adjustable mounting bases on site; ③ Conduct final acceptance using an illuminance meter (accuracy ±5%). This improves space utilization. By using angled projection technology, the spacing between light fixtures is increased from the conventional 1.2m to 1.8m, reducing the number of light fixtures used by 30%.

[0052] In summary, due to the adoption of the above technical solution, the inclined ceiling lighting structure of ancient buildings in this embodiment has the following advantages compared with the prior art:

[0053] This utility model's sloping ceiling and lighting structure for ancient buildings uses a connecting frame to join the top of the two sloping panels of the pointed ceiling, improving the structural strength and buffering performance at the joint and preventing structural damage caused by mutual compression when the pointed structural panels are directly joined. The tiered or stepped central pointed ceiling and edge ceiling are suspended using a first and second hanger to improve assembly stability. Two types of lighting fixtures are installed on the end faces of the ceiling and at the structural joints. Through the placement of enclosures and supporting panels, the lighting fixtures are concealed, the ceiling structure is reinforced, and localized light blocking and layout are achieved, ensuring sufficient light within the ancient building without glare interference. Existing wooden components are reinforced with steel frames, epoxy resin, and carbon fiber cloth to further improve the structural assembly strength.
