摘要

發光二極體（LED）光源目前已經成為主流燈具。在經濟部能源局有計畫地推廣下，政府單位透過採購程序，對於室內照明汰換更新。本文試圖自博物館從業人員角度出發，由實務面介紹博物館辦理展示照明採購作業時，針對LED燈具需要詳列的諸多規格。我們首先討論與LED晶片相關的規格，包括色溫、顯色性、發光效率與功率等。其中針對顯色性，我們介紹了顯色指數（CRI）與近年新發展的量測規範TM-30。而軌道燈具的規格則是本文的介紹重點。我們探討了燈體結構、投光角度，以及可以改變光斑的相關附屬配件，並以實例呈現展示照明效果。此外，我們也介紹了檢驗規範，以確保燈具的使用安全。辦理採購是博物館從業人員重要工作之一，本文透過燈具規格的介紹，希望能夠對於展示照明及燈具採購的進行，有所幫助。

Nowadays, light-emitting diodes (LEDs) are common lighting solutions. Due to the intentional promotion by the Bureau of Energy of the Ministry of Economic Affairs, government agencies have been updating indoor lighting based on LED procurement. In this paper, the required specifications for LED lighting in museums are introduced from the viewpoint of museum staff. First, the specifications of LED chips are discussed, including correlated color temperature (CCT), color rendition, luminous efficiency, and power. For the color rendition measure, color rendering index (CRI) and TM-30 system are presented. The focus of this paper is on the specifications for track lighting. Track lighting configuration, beam angle, and attached accessories for modulating light spots are discussed, with examples of lighting effects. Safety standards and regulatory inspections are also emphasized. Procurement is one of the important tasks of museum staff. Therefore, this discussion of LED lighting specifications should be helpful for museum staff in terms of developing lighting solutions and carrying out procurement duties.
