摘要註:	經濟部能源局2010年統計資料顯示，台灣每年照明用電佔全國總用電量11.3%，辦公室照明耗電占建築總用電量27.2%，改善照明耗能有助於提升建築節能成效。一般辦公室的輕鋼架天花板照明，光源是以T8或T5螢光燈為主。為達成照明節能，發光二極體(LED)或冷陰極管(CCFL)之類的新興節能光源燈具已被開發及使用。這些新節能燈具為提供更換便利性和較低燈具開發成本，基本上還是以T8燈管型式呈現，但不同光源特性卻套用傳統燈具，其適宜性必須被檢視。本研究是以辦公室燈具離地高度240cm的環境，兼顧照度均齊性及照明耗能，提出新節能光源取代傳統螢光燈之使用建議。有關於本研究的九種燈具適用性比較，主要的成果如下：1. 若改變LED和CCFL燈具的燈管設置方向，導致其工作面照度分佈明顯改變的主要因素是燈具構造型式，而非光源類型。2. 在燈中心間距240cm時，側光LED擴散發光板燈具和T8 CCFL條紋管壁燈管燈具的均齊度低於螢光燈具且不符合CIE建議值，分別為0.67和0.68。此情況能隨燈具高度增加而大幅改善，但工作面照度值會減少。其餘五種新興節能光源燈具的均齊度皆符合CIE建議值，且與螢光燈之間無明顯的差異。3. T8 LED霧面管壁燈管燈具和T8 CCFL透明管壁燈管燈具的建議配置方式是燈中心間距240cm。其餘五種新節能光源燈具的配置建議是燈中心間距180cm。此時，T8 CCFL條紋管壁燈管燈具的燈管設置方向為平行基準軸，其餘燈具為垂直基準軸。4. 側光LED擴散發光板燈具能提供相對較高的工作面照度，適用於精細作業需求。LED直下照射擴散型燈具產生的工作面照度低於300lux，適用於低照度需求環境。其餘燈具可輔以工作照明而使用於一般辦公室環境。5. 在一般辦公室，可替代 T8和T5螢光燈的新興節能光源燈具有三種：T8 LED霧面管壁燈管燈具、T8 CCFL透明管壁燈管燈具、T8 LED透明管壁燈管燈具。可替代T8螢光燈者有二種：T8 CCFL條紋管壁燈管燈具、CCFL直下聚光型燈具。 According to the 2010 statistics of the Bureau of Energy, Ministry of Economic Affairs, lighting accounted for 11.3% of total domestic power consumption, whilst office lighting contributed to 27.2% of total power consumption in building sector. Therefore, reducing the lighting energy consumption is able to help enhancing the effectiveness of building energy saving. T8 and T5 fluorescent lamps are the commonly used T-bar ceiling lights in offices. A few of emerging energy-saving lights, such as LED or CCFL, have been developed and used for lighting energy saving. All such newly developed energy efficient light sources can provide the convenience of lamp replacement and a lower cost of developing lighting fixtures, yet they still use the traditional T8 fluorescent tube as the light source, accordingly, the applicability of using entirely different lighting sources by means of traditional lighting fixtures needs to be further investigated. The aim of this research is to propose some practicable suggestions relating to the use of emerging energy-saving light sources to replace traditional fluorescent lamps in an office environment, where the ceiling height is 240cm. Such an evaluation concerns both of the uniformity of illuminance and the lighting energy consumption.Based on the comprehensive analysis and comparison of nine types of lighting fixtures used in this study, the key findings are as follows:1. If the direction of light tubes within a LED or CCFL lighting fixtures is changed, the cause of resulting in noticeable difference in illuminance distribution is the structure of lighting fixture, not the light source itself.2. When the distance between the central points of two lights is 240cm, the uniformity of the edge-lit SMD LED light panel with diffuser and the T8 CCFL straight grain lighting tubes is lower than fluorescent lamps and not in accordance with CIE requirements , which are 0.67 and 0.68 respectively. Such a situation can be improved, if the height of the lighting fixture increases, however, the illuminance on the working plane also will be decreased. The uniformity of the remaining five emerging energy-saving light sources is in accordance with CIE requirements, and have no significant difference with fluorescent lighting fixtures.3. The suggested distance between the central points of the T8 LED light with translucent tube or the T8 CCFL light with transparent tube is 240cm. For the other five emerging energy-saving lights, such a suggested distance is 180cm. Additionally, the direction of the T8 CCFL straight grain lighting tube is set out in parallel with the central line connecting both lighting fixtures. For the rest, the direetion of lighting tube is perpendicular to such a line.4. The edge-lit SMD LED light panel with diffuser can offer a higher illuminance on the working plane, which is suitable for the working environments required higher light level. The LED backlighting luminaire with diffuser is suitable for a working environment with low lighting demands, i.e. the illuminance of the working plane is less than 300lux. The other lighting fixtures are suitable for general office working environments.5. In an office environment, there are three types of emerging energy-saving lights which can replace T8 and T5 fluorescent lamps: T8 LED light with translucent tube, T8 CCFL light with transparent tube and T8 LED light with transparent tube. Both of the T8 CCFL straight grain lighting tubes and the CCFL backlighting luminaire with diffuser can only be used to replace the T8 fluorescent lamps.
