碩士 === 國立虎尾科技大學 === 光電與材料科技研究所 === 99 === 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.
