禹城鋼結構板房的采光設計需兼顧功能性與舒適性，結合當地光照條件與建筑特性，通過自然采光優化、人工照明適配及材料選擇，打造明亮均勻的室內光環境，提升空間使用體驗。

　　The lighting design of Yucheng steel structure panel houses needs to balance functionality and comfort, combined with local lighting conditions and building characteristics. Through natural lighting optimization, artificial lighting adaptation, and material selection, a bright and uniform indoor lighting environment is created to enhance the spatial experience.

　　自然采光是核心設計方向，需根據板房朝向與功能分區合理布局透光區域。南北向板房可在屋頂對稱設置條形天窗，采用透光率達 85% 以上的 PC 陽光板（厚度 8-10mm），并加裝保溫層（如 10mm 巖棉夾芯），既能引入直射光，又可減少冬季熱量流失。天窗間距按板房跨度的 1/3 設置（如 6 米跨度板房，天窗間隔 2 米），確保室內照度均勻度達 0.7 以上。東西向板房則側重側窗設計，在墻體中部設置通長玻璃窗（高度 1.5-1.8 米，寬度占墻面 60%），采用 Low-E 中空玻璃，夏季可減少紫外線射入，冬季保留紅外輻射，配合外側遮陽百葉（可調角度 30°-90°），在上午 10 點下午 4 點陽光強烈時段調節進光量，避免眩光與室內過熱。

　　Natural lighting is the core design direction, and it is necessary to layout the transparent areas reasonably according to the orientation and functional zoning of the prefabricated houses. North south facing panel houses can be symmetrically equipped with strip skylights on the roof, using PC solar panels with a transmittance of over 85% (thickness 8-10mm), and adding insulation layers (such as 10mm rock wool sandwich), which can introduce direct light and reduce heat loss in winter. The spacing between skylights is set at one-third of the span of the prefabricated house (for example, for a 6-meter span prefabricated house, the spacing between skylights is 2 meters), ensuring that the indoor illumination uniformity is above 0.7. The east-west panel house focuses on side window design, with full-length glass windows (1.5-1.8 meters in height and 60% of the wall width) installed in the middle of the wall. Low-E insulated glass is used to reduce ultraviolet radiation in summer and retain infrared radiation in winter. In addition, the outer sunshade louvers (adjustable angle of 30 ° -90 °) are used to adjust the amount of incoming light during the strong sunlight period from 10am to 4pm to avoid glare and indoor overheating.

　　功能分區的差異化采光需求需精準適配。居住型板房的臥室區域，可在床頭上方設置小型采光帶（寬度 30cm，長度與床同寬），采用磨砂 PC 板漫射光線，避免直射影響休息；廚房與衛生間需充足照明，在頂部設置 300×600mm 方形采光窗，搭配透光率 60% 的夾膠玻璃，兼顧隱私與亮度。辦公或商業用途的板房，在進深超過 6 米的區域，于屋頂增設鋸齒形采光帶（傾斜角度 45°），利用反射原理將光線引入室內深處，配合墻面淺色涂料（反射率≥80%），使距離窗戶 5 米內區域的照度可達 300lux 以上（滿足辦公基本需求）。

　　The differentiated lighting requirements of functional zoning need to be accurately adapted. In the bedroom area of residential prefabricated houses, a small daylighting strip (30cm wide and the same width as the bed) can be installed above the head of the bed, using frosted PC boards to diffuse light and avoid direct sunlight affecting rest; The kitchen and bathroom need sufficient lighting, with a 300 × 600mm square skylight window installed at the top, paired with laminated glass with a light transmittance of 60%, to balance privacy and brightness. For office or commercial use, in areas with a depth of more than 6 meters, a serrated skylight strip (tilted at 45 °) is added to the center of the roof. The light is guided into the interior using the principle of reflection, and combined with light colored paint on the walls (reflectivity ≥ 80%), the illumination within 5 meters of the window can reach over 300lux (meeting basic office needs).

　　人工照明系統作為自然采光的補充，需遵循與舒適原則。選用 LED 平板燈（照度 4000K，顯色指數≥80），按功能區劃分布局：走廊與公共區域間距 2 米均勻布置，功率 18-24W；辦公桌面采用可調節臺燈（照度≥500lux），避免屏幕反光；衛生間安裝防霧 LED 燈（IP65 防護等級），確保潮濕環境使用。智能控制系統可提升照明效率，通過光感傳感器自動調節燈具亮度（如自然光充足時降 50% 功率），并設置定時開關（如凌晨 12 點早 6 點自動調低 30% 亮度），相比傳統照明 40% 以上。

　　Artificial lighting systems, as a supplement to natural lighting, should follow the principles of energy conservation and comfort. Select LED flat panel lights (illumination 4000K, color rendering index ≥ 80), layout according to functional areas: evenly arrange corridors and public areas with a distance of 2 meters, power of 18-24W; use adjustable desk lamps (illumination ≥ 500lux) on office desks to avoid screen reflection; Install anti fog LED lights (IP65 protection level) in the bathroom to ensure safe use in humid environments. The intelligent control system can improve lighting efficiency by automatically adjusting the brightness of the lamps through light sensors (such as reducing to 50% power when natural light is sufficient), and setting a timer switch (such as automatically reducing to 30% brightness from 12 am to 6 am), saving more than 40% energy compared to traditional lighting.

　　材料選擇與構造細節決定采光效果的長期穩定性。屋頂采光板與鋼結構框架的連接處，采用三元乙丙橡膠密封條（厚度 3mm）和不銹鋼壓條固定，坡度控制在 15°-20°，確保雨水順暢排出，避免滲水影響透光性。側窗玻璃與鋼框架之間預留 5mm 伸縮縫，填充硅酮密封膠（位移能力 ±25%），適應鋼結構熱脹冷縮（禹城地區溫差達 30℃以上，需預留足夠變形空間）。室內吊頂采用穿孔鋁板（穿孔率 20%），兼具光線漫射與通風功能，配合暗藏的 LED 燈帶，在夜間營造柔和的環境光，減少強光直射帶來的視覺疲勞。

　　The material selection and construction details determine the long-term stability of the lighting effect. The connection between the roof skylight panel and the steel structure frame is fixed with EPDM rubber sealing strips (thickness 3mm) and stainless steel pressure strips, with a slope controlled at 15 ° -20 ° to ensure smooth drainage of rainwater and avoid water seepage affecting transparency. Reserve a 5mm expansion joint between the side window glass and the steel frame, filled with silicone sealant (displacement capacity ± 25%), to adapt to the thermal expansion and contraction of the steel structure (sufficient deformation space needs to be reserved in Yucheng area with a temperature difference of over 30 ℃). The indoor ceiling is made of perforated aluminum panels (perforation rate of 20%), which have both light diffusion and ventilation functions. Combined with hidden LED light strips, it creates a soft ambient light at night and reduces visual fatigue caused by strong direct light.
