照明在室內空間佔有極重要角色。室內光源從早期使用燭火到鹵素燈、白熾燈,直到近年來為了考量節能而研發出LED光源,對於日常生活而言是一項重要的貢獻。今日,LED光源發光效率提高、銷售價格大幅降低,造就市面上出現來源不同的MR LED杯燈。由於LED光源應用於室內照明相關案例鮮少,且相當適合取代鹵素杯燈在櫥窗展示設計中的重要地位,因此,本研究以LED杯燈特性探討在櫥窗展示空間的適切性,並藉由模擬其照明應用效果以說明LED杯燈之特點。 本研究選擇市面上LED杯燈為實驗樣本,測試其照明實驗參數(平均照度、照度均齊度、發光效率、配光曲線及光束角、演色值、色溫及色彩表現)。其次,建構代表性櫥窗展示空間,並將LED杯燈應用於3D模擬櫥窗展示上(透過DIALux模擬實驗),藉以比較LED杯燈的照明及視覺效果。最後,本研究依據LED杯燈特性,歸納其照明應用特點。最後得知,在本研究所選用之LED杯燈中,以光束角28°之3wLED杯燈在尺寸為45cm(長)×45cm(寬)×60cm(高)之櫥窗展示單元中,可呈現最佳照明情境。
Illumination plays an important role in interior space. To come up with a better lighting quality, men have tried using candle flame, tungsten lamps, halogen lamps, fluorescent tubes and incandescent lamps. In recent years for considering the energy saving, Light Emitting Diode (LED) lamps can make us saving energy a lot, and it’s really an important contribution to our daily life. Nowadays, the LED light luminous efficiency enhanced and the selling price largely reduces to bring out the assorted LED on the market. Because the applications of LED light source rarely in the interior illumination and it is quite suitable for the substitution halogen lamp in show cases demonstration design important status. Therefore, this research by the LED MR lamp characteristic discussion demonstrates the space in show cases appropriateness, and to simulate its illumination applications informs the consumer about the characteristic of LED MR lamp. This research choose LED MR lamp as an experiment sample to measure its efficiency and operational parameter such as average illuminance, illuminance uniformity, luminous efficacy, photometric curve, beam angle, color rendering index, texture, correlated color temperature and spectrum. Secondly, we constructed the symbolized showcase and applied the LED MR lamp in the 3D showcase (through DIALux experiment) to show up the lighting and vision outcome. At last, according to the characters of LED MR lamp, we concluded the features of illumination would come with the best condition in the showcase by 45 cm (Length) ×45cm (width) ×60cm (hight) and 28° luminous angle of 3w LED.
