博物館節能改善規劃與照明光源適用性探討

A Discussion on Improvements of Energy Saving and Lighting in the Museum

由於照明在博物館類建築中，是除了空調外最大的電費預算支出，本研究進行工博館照明之改善部分，乃針對光源之發光效率及其環保性進行探討。檢討發現工博館一般空間在節能及環保考量上，最值得優先改善的為日光燈管，以T8及T5三波長燈管取代一般傳統燈管；就節能、演色性及維護性而言，目前仍以陶瓷複金屬燈最適合應用在展示上，並用以取代以往大量應用在展示照明上的鹵素燈。雖然LED目前尚不適於做為一般空間或展示照明，但由於LED具有發光效率高、耗電量少、使用壽命長、安全可靠性強及有利於環保等優勢，就長期而言，LED仍是最被看好的新一代綠色光源。

Because lighting is the largest electric expenditure besides air conditioning in the museum, this research tries to discuss the luminous efficiency and environmental friendliness on the improvements of NSTM lighting. Considering energy saving and environmental protection the priority would be replacing the fluorescent lamps with T8 tri-phosphors and T5 lamps in the general space of NSTM. In terms of energy saving, color rendering and maintenance, the ceramic metal halide lamps best suit in exhibitions and can replace a large amount of the halogen lamps. At present LED is not suitable for illuminating in the general space or exhibition areas. However, in the long term its high efficiency, little power consumption, long duration, safety and environmental friendliness make it a favorite green light source of the new generation.
