摘要
台灣的照明用電約260億度電，占全國總用電2,298億度之11.3％，已成為僅次於冷氣空調的電力負載，根據2008年非製造業能源查核年報，系統別節能改善案例統計以「空調系統」之節能改善案例數最多，最為一般大能源用戶所重視，其次為「照明系統」，以國內現況而言，照明用電的節能仍有相當的改善空間。 隨著科技的進步和節能的意識抬頭，照明系統在光源、燈具、控制、設計上已大幅提升效率，加上節能管理指標與政策的訂定更擴大了節能的改善空間。 節約照明用電的過程中也要注意到合理的照明，並注意照明品質的舒適性，讓我們的工作效率更高，依不同的場合選擇不同的照明方式，讓心情更加舒暢。 本報告針對照明用電，提出使用發光效率較高的人工光源代替發光效率較低的人工光源，以電子安定器取代傳統安定器，定期更新燈管與擦拭燈具、燈管，維持燈管在高效率的狀況下運作，白天多利用自然採光以減少電力照明，裝設分區開關、個別開關、時序控制器、晝光感知器、熱感開關、中央監控系統或二線式照明控制系統等，以達減少照明的耗電量並提升照明的品質。本報告也提出12個在照明節能方面的成功實例，供大家做為實際照明用電的參考。

Lighting has been a major part of electricity consumption in Taiwan. According to the statistics, revealed in the Energy Audit Annual Report for Non-manufacturing Industries, 2008, lighting takes about 12% in the total annual consumption of electricity in Taiwan. The present researches on eletricity savings focus majorly on the improvement of air-conditioning, and on lighting is the second major.The total annual consumption of electricity in Taiwan is 229.8 billion KWH and the consumption in lightning is 26 billion KWH (2008), which takes a percentage of 11.3%, second to the consumption in air-conditioning. Although there has been a large amount of projects related to energy savings conducted during the past decade, they are aimed mainly in the improvement of air-conditioning. As for lighting, it seems not the major concern. Due to the application of new technologies and the promotion of the ideas revolved in saving energy and natural resources, the improvement of lighting has achieved some siginificnet goals in the design and manufacturing of lighting equipment. The establishment of new energy-saving standards and related policies also increase the efficeincy in lighting. In addition to saving energy, the quality and comfortablity should also be concerned during the process of designing and manufacturing lighting equipments. This report discusses some crucial aspects related to the deisgn and development of lighting systems. This report, including 12 successful cases in saving energy and reducing energy consumption in lighting, suggests some possible ways to improve the efficiency of lighting. For example, replace the artificial light sources of low luminous efficiency with those of high luminous efficiency; use electronic ballasts rather than traditional magnetic ballasts; change old light tubes and clean the light equipment regularly to keep the tube working in a high-efficient situation. Moreover, it is a good way to save energy by using the natural sunlight during the daytime. There are also some devices that can used to improve the quality of light and reduce the consumption of energy, such as wide area switches, individual switches, timing controllers, photo sensors, thermostat switches, direct digital control (DDC)systems and two-way lighting control systems. With these technology, lighting can be more efficient
