Description

本発明は、光源アセンブリに関する。 The present invention relates to a light source assembly.

バックライトモジュールでは、技術とコストを考慮して、ライトバー（light bar）の固定方式が次第に改良されてきている。早期のライトバーは、熱伝導性パッド（thermal pad）を使ってネジ固定の方式でバックプレートに固定され、今は、通常、粘性結合の方式でバックプレートに固定される。図１の光源アセンブリ１００に示すように、ライトバー１０４が、熱伝導性両面接着テープ（thermal tape）１０６によりバックプレート１０２に接着固定される。しかし、熱伝導性両面接着テープ１０６を使うと、剥離又は脱落の問題が生じやすく、特に、ライトバー１０４の頭尾両端では、その問題がより著しい。ライトバー１０４とバックプレート１０２との間の熱伝導性両面接着テープ１０６の一端に剥離が発生したときに、ライトバー１０４とバックライト１０２との間の位置決めの信頼性が低下することがあり、さらに悪化すると、ライトバー１０４が次第に完全に脱落する恐れがあり、光源からの熱が集中して放熱しにくくなり、これにより、光学効率が低下し、バックライトモジュール全体の効能、信頼性及び品質が劣化してしまう。 In the backlight module, a light bar fixing method is gradually improved in consideration of technology and cost. The early light bar is fixed to the back plate by a screw fixing method using a thermal pad, and is usually fixed to the back plate by a viscous bonding method. As shown in the light source assembly 100 of FIG. 1, the light bar 104 is adhesively fixed to the back plate 102 by a thermally conductive double-sided adhesive tape 106. However, when the heat conductive double-sided adhesive tape 106 is used, the problem of peeling or dropping is likely to occur, and the problem is more remarkable at both the head and tail of the light bar 104. When peeling occurs at one end of the thermally conductive double-sided adhesive tape 106 between the light bar 104 and the back plate 102, the positioning reliability between the light bar 104 and the backlight 102 may be reduced. If it further deteriorates, the light bar 104 may gradually fall off completely, and heat from the light source concentrates, making it difficult to dissipate, thereby reducing the optical efficiency and improving the overall effectiveness, reliability, and quality of the backlight module. Will deteriorate.

図２は、本発明の一実施例による光源アセンブリを示す図であり、図３及び図４は、図２の局部拡大図Ｍ及びＮである。図２乃至図４を参照する。光源アセンブリ１０は、バックプレート１２及びライトバー１４を含み、バックプレート１２は、底部１２ａ及び少なくとも一つの側部１２ｂを含み、バックプレートの底部１２ａは、導光板１８の底側に設置され、且つ、バックプレートの側部１２ｂとバックプレートの底部１２ａとは、所定の角度を成し、本実施例では、バックプレートの側部１２ｂとバックプレートの底部１２ａとは、例えば、互いに垂直であるが、本発明は、この実施例に限定されない。ライトバー１４は、導光板１８の入光面１８ａに隣接する位置に設置され、且つ、バックプレートの側部１２ｂに貼られ、例えば、ライトバー１４は、熱伝導性両面接着テープ１６によりバックプレートの側部１２ｂに粘着されても良い。バックプレートの側部１２ｂは、例えば、縦長い外形を有し、且つ、バックプレートの側部１２ｂの長手軸方向において相対する第一端Ｐ及び第二端Ｑを有する。第一押圧片２２は、バックプレートの側部１２ｂの第一端Ｐに形成され、且つ、第二押圧片２４は、バックプレートの側部１２ｂの第二端Ｑに形成される。本実施例では、第一押圧片２２は、基部２２ａ及び湾曲部２２ｂを含み、基部２２ａは、バックプレートの側部１２ｂに接続し、湾曲部２２ｂは、基部２２ａに接続し、また、バックプレートの側部１２ｂに面し、且つ、湾曲部２２ｂとバックプレートの側部１２ｂとの間は、隙間を有する。同様に、第二押圧片２４は、基部２４ａ及び湾曲部２４ｂを含み、基部２４ａは、バックプレートの側部１２ｂに接続し、湾曲部２４ｂは、基部２４ａに接続し、また、バックプレートの側部１２ｂに面し、且つ、湾曲部２４ｂとバックプレートの側部１２ｂとの間は、隙間を有する。よって、湾曲部２２ｂ、２４ｂは、それぞれ、バックプレートの側部１２ｂと収納空間を形成する。ライトバー１４の相対する両端が、それぞれ、第一押圧片２２及び第二押圧片２４とバックプレートの側部１２ｂとが形成する収納空間内に置かれるときに、第一押圧片２２、第二押圧片２４の湾曲部２２ｂ、２４ｂとバックプレートの側部１２ｂとの間の隙間が、実際の状況に応じて調整され得るので、ライトバー１４の両端が、それぞれ、第一押圧片２２及び第二押圧片２４に当接し又はそれと嵌合することができ、これにより、良好な位置決め効果を得ることができる。具体的に言えば、第一押圧片２２、第二押圧片２４の湾曲部２２ｂ、２４ｂとバックプレートの側部１２ｂとの間の隙間が比較的に大きいときに、ライトバー１４の両端が、それぞれ、第一押圧片２２及び第二押圧片２４中に置かれ、ライトバーをバックプレートの所定の位置に固定することができる。また、第一押圧片２２、第二押圧片２４の湾曲部２２ｂ、２４ｂとバックプレートの側部１２ｂとの間の隙間が比較的に小さいときに、ライトバー１４の両端が、それぞれ、第一押圧片２２及び第二押圧片２４中にしっかり留められ、これにより、湾曲部２２ｂ、２４ｂによってライトバー１４の両端をさらに挟むことになる。よって、ライトバー１４とバックプレート１２との間の熱伝導性両面接着テープ１６に劣化や剥離などが生じても、ライトバー１４は、依然として、第一押圧片２２及び第二押圧片２４によりバックプレート１２の所定の位置に固定され得る。 FIG. 2 shows a light source assembly according to an embodiment of the present invention, and FIGS. 3 and 4 are local enlarged views M and N of FIG.
