Description of the Invention: [Technical Field of the Invention] The present invention relates to a light source assembly. [Prior Art] Under the technical and cost considerations of the backlight module, the fixing method of the light bar is gradually improved. Early light strips were attached to the backing plate by means of thermal pads and screwing, and are currently attached to the backing plate in a viscous manner. As shown in the light source assembly 100 of FIG. 1, a light bar 1〇4 is adhered to the back plate 102 by a thermal tape 106. However, the heat-conductive double-sided tape 1〇6 is liable to cause peeling or peeling, and in particular, the head and the tail ends of the light bar 104 are more prominently adhered. When the end of the thermal double-sided tape 1〇6 between the light bar 1〇4 and the back plate 102 is peeled off, the positioning reliability between the light bar 1〇4 and the back plate 102 is lowered, and if it is worse, the light bar will be caused. 1〇4 gradually degumming 'to concentrate the heat generated by the light source without dissipating, resulting in reduced optical efficiency and degrading the overall performance, reliability and quality of a backlight module. In addition, Taiwan Patent Publication No. 200811522, 201007276, 200928500 and U.S. Patent Publication No. 20080186425 disclose a fixing method of a light source of a backlight module.

以下實施例中所提到的方向用語，例如：上、下、左、右、 前或後等，僅是參考附加圖式的方向。因此，使用的方向用 語是用來說明並非用來限制本發明。 圖2為依本發明一實施例之光源組件的示意圖，圖3及 圖4為圖2的局部放大圖Μ、N。請參考圖2至圖4，光源 組件10包含一背板12及一燈條14,背板12包含一底部 12a及至少一側部12b，且背板側部12b與背板底部12a夹 —角度，在本實施例中，背板側部12b與背板底部12a例 如為相互垂直，但本發明並不限於此實施例。燈條Η貼附 於背板側部12b上，舉例而言，燈條14可藉由一導熱雙面 膠（thermal tape) 18黏貼於背板侧部12b上《燈條14具有一 201204982 縱長外形，因此於燈條14的一長軸方向上具有相對的一第 一端P及一第二端Q。燈條14具有複數個可排列為一橫列 的發光元件141、及位於這些發光元件141兩側的一第一連 接器142(connector)及一第二連接器143，第一連接器H2、 第一連接器143例如可分佈電極及電路走線。於本實施例 中’背板底部12a形成有一第一扣孔121及一第二扣孔122, 第一扣孔121鄰近燈條14的第一端P且第二扣孔122鄰近 燈條14的第二端Q ^ —第一卡扣件22的一端抵靠燈條14 且另一端嵌入第一扣孔121，一第二卡扣件24 —端抵靠燈條 14且另一端嵌入第二扣孔丨22。當第一卡扣件22及第二卡 扣件24分別嵌入背板底部i2a的第一扣孔121及第二扣孔 122後，第一卡扣件22及第二卡扣件24可分別抵住燈條14 相對的兩端P、Q而獲得限位燈條14的效果。因此，即使燈 條14與背板12間的導熱雙面膠18出現劣化或剝離的情形， 燈條14仍然可以藉由第一-扣件22、第二卡扣件24限位於 背板12上。再者，因第一卡扣件22及第二卡扣件24於分 別嵌入第一扣孔121及第二扣孔122後係位於一導光板(未圖 示)與燈條14之間，如此當導光板因受熱變形或因外力或其 它因素移位時，第一卡扣件22及第二卡扣件24可保護燈條 14不被導光板撞擊。 圖5為依本發明一實施例的卡扣件示意圖，圖6為顯示 卡扣件與扣孔的搭配卡合方式示意圖。圖5及圖6係以第一 201204982 朴件22為舰明卡扣件的結構型態，因第二卡扣件μ與 第卡扣件22的結構型態相同故於此不再費述。請同時參 考圖5及圖6，於—實施例中，第一卡扣件a的底部具有一 τ字形截面外型的卡榫221，且苐—卡扣件22面向燈條14 的’具有-缺π Π因此當第一卡扣件a的卡棒切卡 ^第一扣孔121後’第一卡扣件22可牢固地固定在背板底 料連142 _可置人第—_卜扣件22的缺 口 222内’使第-卡扣件22可抵住燈條M，達到限位燈條 14的效果。於本實施例中，因第—連接器142可置入第一卡 扣件22 #缺口 222内，可進一步提供保護連接⑽2的效 果。當然，第一卡扣件22、第二卡扣件24的外形及與扣孔 間的搭配鶴並不限定，僅需能提供卡合效果ϋ達到限位燈 條14的目的即可。再者，第一卡扣件22及第二卡扣件24 可由彈性材料所構成，例如為塑膠材料。 圖7為本發明另—實施例的光源組件的示意圖。於此為 π楚表現背板32與散熱# 36的連雛態，導光板杯係以 虛線表不。如® 7所示，光源組件30包含-背板32、-燈 條34及-散熱片36。背板32設置於導絲46的一底側， 散熱片36設置於鄰近導光板46的一入光面46&的位置處且 連接背板32的底部平面32a的—側。散熱片％具有一底部 36a及-側部36b，且散熱片底部恤與散熱片側部 36b 夹一 角度。燈條34貼附於散熱片侧部挪上舉例而言，燈條 11 201204982 34可藉由一導熱雙面膠38黏貼於散熱片側部36b上。燈條 34具有一縱長外形，因此於燈條34的一長軸方向上具有相 對的一第一端S及一第二端T。燈條34具有複數個可排列為 一橫列的發光元件34卜及位於這些發光元件341兩側的一 第一連接器342及一第二連接器343。於本實施例中，散熱 片底部36a形成有一第一扣孔361及一第二扣孔362，第一 扣孔361鄰近燈條34的第一端S且第二扣孔362鄰近燈條 34的第一端T。當第 ^扣件42及第二卡扣件44分別嵌_入 散熱片底部36a的第一扣孔361及第二扣孔362後，第一卡 扣件42及第二卡扣件44可分別抵住燈條34相對的兩端S、 T而同樣獲得限位燈條34的效果。於本實施例中，燈條34 與散熱片36結合再連接背板32的方式，可有效提高結構強 度及散熱效果、且易於模組化。當然，散熱片36的外形並 不限定，例如可具有一 L字型或一 τ字型的截面外形等均可。 圖8為本發明另一實施例的光源組件的示意圖。於本實 施例中，光源組件70包含兩個燈條54a、54b，且兩相鄰燈 條54a、54b彼此相連並形成一接點w。兩個燈條54a、54b 貼附於一散熱片76的側部76b,且散熱片76的底部76a連 接背板52的底部的一側。第一_^扣件62、第二卡扣件64、 第二卡扣件66分別嵌入散熱片底部76a並抵住燈條54左 端、燈條54b右端及兩燈條54a、54b的接點W，同樣可獲 得良好的定位效果。再者，如圖9的光源組件8〇所示，亦 12 201204982 可利用一壓片82抵住兩個相連燈條54a、54b的中間接點 W’亦即第一卡扣件62、第二卡扣件64及壓片82可分別抵 靠兩個相連燈條54a、54b的左端、右端及中間接點w，使 複數個相連的燈條54a、54b獲得良好的定位效果。當然。上 述實施例同樣可應用於如圖2所示燈條貼附於一背板侧部的 情況。 綜上所述，本發明之實施例的光源組件至少具有下列 其中一個優點： 藉由上述實施例之設計，於背板或散熱片上形成扣孔， 並藉由卡扣件的卡合效果可將燈條牢固地限位於背板或散 熱片上，因此可有效避免燈條於背板或散熱片上的翹曲、脫 落或剝離現象，而可提高光源組件的品質及可靠度與發光 元件的壽命及發光效率，且位於導光板與燈條間的卡扣件可 保護燈條不被導光板撞擊。另外，上述設計的元件構成及組 裝作業相當簡易、迅速，故不會導致成本增加即能額外提供 定位強化效果。再者，背板或散熱片的底部與側部可互成一
