本研究是以在紅色聚酯布、藍色聚酯布、綠色聚酯布、黃色聚酯布等四種顏色會隨著濃度上升，L*值會隨之下降，LUX值也會隨之下降。可得知紅色聚酯布與紅色聚酯布加冷光片之不同濃度進行的L*值分析，實驗得知紅色聚酯布濃度為0.1%時，L*值為51.43，紅色聚酯布濃度為2%時，L*值為44.6，紅色聚酯布加冷光片濃度為0.1%時，L*值為52.25，紅色聚酯布加冷光片濃度為2%時，L*值為45.77。並佐證黃色聚酯布和螢光黃與冷光片貼合後之不同濃度進行的L*值分析，黃色聚酯布從濃度為0.1%至2%時，隨著濃度增加，L*值會隨之下降，黃色聚酯布貼合冷光片後最低濃度為0.1%至2%時，隨著濃度增加，L*值會隨之下降，黃色聚酯布與螢光黃與冷光片貼合後最低濃度為0.1%至2%時，隨著濃度增加，L*值會隨之下降。

In this study, in the four colors of red polyester fabric, blue polyester fabric, green polyester fabric, and yellow polyester fabric, the L*value will decrease as the concentration increases, and the LUX value will also decrease. It can be known that the L* value of the red polyester cloth and the red polyester cloth plus the luminescent film are analyzed at different concentrations. When the concentration of the red polyester cloth is 0.1%, the L* value is 51.43, and the red polyester cloth concentration is 2%. The L* value was 44.6, the L* value was 52.25 when the red polyester cloth plus luminescent sheet concentration was 0.1%, and the L*value was 45.77 when the red polyester cloth plus luminescent sheet concentration was 2%. The L*value of different concentrations of the yellow polyester cloth and the fluorescent yellow and the luminescent film were measured. The L* value decreased with the increase in the concentration of the yellow polyester cloth from 0.1% to 2%. When the minimum concentration of the yellow polyester cloth is below 0.1% to 2%, the L* value will decrease as the concentration increases, and the minimum concentration after the yellow polyester cloth and the fluorescent yellow and the cold light sheet are affixed is 0.1. From 2% to 2%, the L* value decreases as the concentration increases.
