中文摘要 | 都市公園之全面性照明,其光源種類繁多,維護成本甚高,且對視環境品質影響最鉅,而光源之演色條件及色溫性質關係著環境事物的色彩呈現,且色彩呈現能否達成視覺品質之首要條件。本研究採取實地光源模擬,並配合語意分析法及滿意度之問卷調查,進行視覺感知實驗,最後將所得數據,進行統計分析。研究結果顯示,受測者對高壓納燈的接受度(50.4%)明顯較其他種類光源低,受測者的性別及教育背景差異會造成視覺感知差異。受測者對視環境的滿意度會受到環境的演色效果影響,且受測者會產生共同偏好之色溫值,即於低照度下偏好暖色光,並集中在2700˚K之值,而藉由演色值的提升,安全感亦增加。於同一環境下,對69之演色值接受度已達78%以上,當演色值增至某一臨界值81Ra時,即使再增加演色值,受測者便無法明顯感受其差異。 |
英文摘要 | The light for lighting urban parks is as diverse in variety as high in maintenance cost, and dictates the visual environment quality. Meanwhile the lighting's colour rendering and colour temperature determine the effect of the environment's colour showing, and are the primary conditions to achieve the desired visual quality of colour showing. This study adopted on-the-spot lighting simulation, and employed the Semantic Differentiated Method and questionnaire survey in conducting the visual perception experiment, and then carried out the income data statistical analysis. The result of the experiment showed that the testees had lower receptiveness (50.4%) for High-Pressure Sodium Lamp than other sorts of lamp. Furthermore gender and education level influenced visual perception. The testees were affected by the colour rendering of environment and had common predilections of colour rendering index. Which meant they preferred warm colour light of low illuminant, and the predilection of colour rendering index was around 2700˚K. Secure feeling also rose as the colour-rendering index increased. In the same environment, receptiveness for colouring rendering index of 69 was over 78%. However when the colour-rendering index reached 81 Ra, the testees could not perceive any difference even though the index had been increased. |
