摘要

發光二極體(Light Emitting Diode)簡稱LED，隨著地球能源減少大家提倡節能減碳作環保，發光二極體剛好符合此條件體積小、省電、無污染、壽命長、價格低，而現今很多電子產品運用LED特性製造出了LCD背光源、筆記型電腦背光源，在照明上也作了一大突破，例如：LED T-Bar燈具、筒燈6吋、8吋、LED台燈、公車到站顯示器、小綠人、紅綠燈、MR16等…為節能減碳創下歷史新紀錄，也造就無限商機與工作機會。
本論文是研究LED T-Bar燈具應用於室內照明， 我們將燈具內側貼上高反射係數材料UX188與RE-240T，並量測反射貼片對燈具整體發光特性的影響。從實驗結果發現LED T-Bar燈具內側貼上RE-240T反射片，在光強度方面是最強的，約為1096.6 cd，但是在總光通量方面，內側貼上UX188反射片的總光通量是最大的，約為2815 lm。然後，我們比較發光效率，貼有RE-240T的為78.23 lm/W，而貼有UX188的為80.8 lm/W。因此，在本研究裡認為UX188反射貼片對LED T-Bar燈具，無論在總光通量或是發光效率都具有最好的提升效果。

Light Emitting Diode is abbreviated as LED. Along with the energy of the earth reduces, energy saving and carbon reduction is advocated. LED just match this condition, small, save the electricity, pollution-free, long use, low price, a lot of electronic products use LED characters to produce LCD backlight source, backlight source of notebook computer, and also have done a great breakthrough in lighting too. For example: LED T-Bar lamps and downlight, LED desk lamp, bus station display of approaching, little green person traffic light, MR16 etc., all these create the new history of energy saving and carbon reduction, and bring up the limitless business opportunities and working opportunities.
This thesis studies LED T-Bar lamps to apply to room lighting. Sticking the inside of the lamps with the material of high reflection coefficient UX188 and RE-240T, and measure how the reflection stickers influence the characteristic of lamp radiation. From the experimental result, we can find the strongest luminous intensity is when the LED T-Bar with RE-240T reflection film sticking inside, about 1096.6 cd. But in total luminous flux, the biggest one is when the lamp sticks UX188 reflection film inside, about 2815 lm. Then, we compare the luminous efficiency, stuck with RE-240T is 78.23 lm/W, and stuck with UX188 is 80.8 lm/W. Therefore, in this research the UX188 reflection film proves a better improvement either in total luminous flux or in luminous efficiency.
