TW0788F(力捷).Ptd 第4頁 560169 五、發明說明(2) 需要注意的是,光源1 0 2之發光量並不十分均勻,以 光源1 0 2之整個管身而言,靠近光源1 0 2之燈管中間的光線 強度較強,而靠近光源1 0 2之燈管兩端的光線強度較弱。 也就是說,光源102之管身中央附近所發射之光線較其管 身兩端附近所發射之光線還要強。當所有光線沿著第2圖 之箭頭2 5 0之方向照射在稿件11 〇上時,稿件11 〇之中央位 置附近之輝度(luminance)將高過稿件110之兩端附近之 輝度,產生輝度不均勻之現象。倘若光機1 〇 1接收到稿件 11 0所反射之光線後,光機1 〇 1所擷取之掃描影像因此產生 失真現象,影響掃描品質甚鉅。 為了解決所產生之輝度不均勻現象,有些業者便在燈 座103之反射片204上作改良,如第3圖及第4圖所示。在第 3圖及第4圖中,反射片202之靠近缺口 204之兩邊緣分別貼 上砍光片302a及302b ’用以削弱光源1〇2之管身中央所發 射之光線強度,使得光線可以均勻地照射到稿件i i 〇上, 以改善輝度不均勻之現象。 然而,在燈座103之内壁依序加裝反射片202、砍光片 302a及30 2b,將會增加組裝時間及整體生產成本。甚至, 當使用時間過久或黏貼效果不佳時,反射片202、砍光片 3 0 2a及30 2b亦會有毀損或脫落之現象,更換此些毀損之零 件亦讓使用者感到相當不便。 ' 【發明目的及概述】 有鑑於此’本發明的目的就是在提供一種高反射率之TW0788F (Lijie) .Ptd Page 4 560169 V. Description of the invention (2) It should be noted that the light output of the light source 102 is not very uniform. As for the entire tube of the light source 102, it is close to the light source 1. The intensity of the light in the middle of the tube of 0 2 is strong, and the intensity of the light at the ends of the tube near the light source 102 is weak. That is, the light emitted near the center of the tube of the light source 102 is stronger than the light emitted near the ends of the tube. When all the light is irradiated on the manuscript 11 〇 along the direction of the arrow 2 50 in the second figure, the luminance near the central position of the manuscript 11 〇 will be higher than the luminance near the two ends of the manuscript 110, resulting in a luminance difference Uniform phenomenon. If the optical machine 101 receives the light reflected by the manuscript 110, the scanned image captured by the optical machine 101 will cause distortion, which will greatly affect the scanning quality. In order to solve the uneven brightness phenomenon, some manufacturers have made improvements on the reflecting sheet 204 of the lamp holder 103, as shown in Figs. 3 and 4. In Figures 3 and 4, the two edges of the reflective sheet 202 near the notch 204 are respectively pasted with light-cutting sheets 302a and 302b 'to weaken the light intensity emitted from the center of the tube body of the light source 102, so that the light can Irradiate the manuscript ii 0 evenly to improve the uneven brightness. However, adding the reflective sheet 202, light-cutting sheets 302a, and 30 2b in order on the inner wall of the lamp holder 103 will increase assembly time and overall production cost. Even when it is used for a long time or the adhesive effect is not good, the reflective sheet 202 and the light-cutting sheet 3 2a and 30 2b may be damaged or peeled off. It is inconvenient for the user to replace these damaged parts. '[Objective and Summary of the Invention] In view of this, the object of the present invention is to provide a high reflectance
