以Lightscape電腦模擬櫥窗照明設計之研究

櫥窗照明設計，隨著國際資訊及流行性交流頻繁之時，在消費者的視覺感受上已能得到較多新穎資訊。過去傳統櫥窗設計只在乎亮度的多寡，來吸引消費者視覺注目，但隨著節能減碳的訴求，過度的亮度不但造成路人眩光問題以及是否達到消費者視覺焦點，這都是設計師都所要探討了解的課題。所以本次的研究將透過文獻探討方式瞭解設計者應用LIGHTSCAPE電腦模擬潛在機會，以及受測者對於櫥窗照明設計之最佳燈光排列結果及看法，作為本次研究內容。研究結果：（1）由七位學者的論文整理中，發現學者們對於LIGHTSCAPE的應用分析結果，顯示室內外光環境實測結果與模擬結果相當一致，確實可有效的反映空間之光環境狀況，亦為設計或評估之有效預測工具。（2）本實驗以網路受測者樣本數375人，根據實驗分析結果受測者認為最佳的櫥窗照明效果為TYPE_J（下投式、背投式、側投式、上投式燈光）、而最差為TYPE_C（背投式、側投式燈光）。（3）經研究分析之後下投式燈光在櫥窗照明設計之中必須納入規劃設計之一，另外燈光配置上以三種以上之投射型式較能將櫥窗空間照明呈現較為滿意效果。

Moreover information on the visual perception of consumes can be collected for the design of showcase lighting as the information exchange becomes more convenient and frequent. In the past, showcase design only concerned about the intensity of lighting to attract the intention of consumers. However, due to the environmental awareness on energy-saving and carbon reduction, excessive brightness may lead to glare problem to pedestrians and doubt in the effectiveness of lighting. Therefore, this study conducted literature review to find out the feasibility for designers to use Lightscape software for computer simulation, and further test the consumers' perceptions on the optional lighting arrangement.The results are as follows: (1) According to the review on seven researches, it is found that the analytical results obtained by Lightscape simulation are consistent with the outdoor lighting environment test, indicating that Lightscape could effectively reflect the lighting in space and is an effective prediction tool for design or evaluation.(2) The number of test samples of this study was 375. It was found that the optimal showcase lighting effect was TYPE_J (downward, rear, side, and upward projection), and the worst effect was TYPE_C (rear and side projection).(3) According to the results, downward projection should be included in the planning of showcase lighting, and used along with over three types of projection in order to create satisfactory results.
