本研究針對多孔性輕金屬綠建材之設計與熱傳特性做有系統的研究探討，多孔性輕金屬綠建材之基材採用閉孔式發泡鋁材，當LED燈具嵌入安裝時，可以藉由閉孔式發泡鋁材的相對高熱傳導能力提供LED燈具增強散熱的可能。本研究以實驗方法量測當LED燈具嵌入閉孔式發泡鋁材天花板時的局部溫度分布情形與整體熱傳增益效果，對照組則為木製天花板，實驗結果指出本研究之閉孔式發泡鋁材能有效降低LED燈具散熱座整體熱阻達20%以上，且閉孔式發泡鋁材遠比木板具有更高的防火等級，密度也較木板略小，證明其做為質量輕與安全性高的防火綠建材的潛力。

This work systematically studied the design and heat transfer characteristics of the porous light-metal green building materials. The base materials of this porous light-metal green building materials were closed-cell aluminum foams. When the LED lamp is inserted into this porous materials, the porous materials may enhance the heat transfer capacity of the heat sink of LED lamp due to their high thermal conductivity. This work experimentally measured the local temperature distributions and the total heat transfer performance of the LED lamp inserted into the aluminum-foam ceiling. The control group was the wooden ceiling. The experimental results indicate that the present porous ceiling reduced the total thermal resistance of LED lamp by 20%. Besides, the fire-insulation level of the closed-cell aluminum-foam materials are much higher than those of wooden materials; while the density of the front is somewhat lower than that of the rear. This study demonstrates the potential of the closed-cell aluminum foams as the light and safe green building materials with fire-insulation function.
