Description
本發明關於一種背光模組。The invention relates to a backlight module.
背光模組若累積過多的熱，會使發光元件的溫度局部上升，造成發光效率下降、色度偏移及壽命衰減現象。請參考圖4，目前習知背光模組100的散熱途徑，主要透過燈條102將其產生的熱傳導至金屬散熱片106，透過金屬散熱片106吸收部份熱再將部份熱傳導至背板108而與外界冷空氣進行熱交換。然而，為增加燈條102的混光距離，需降低抵靠在燈條102背面102a(背向導光板104的一面)的金屬散熱片106的厚度d，如此容易使熱阻過大而產生熱堆積，導致燈條102的溫度過高。另外，為了背光模組100的薄形化需求，背光模組100的整體厚度需降低，例如降低燈條102下方的金屬散熱片106的高度h，如此容易使熱阻過大，熱量傳導不易而產生熱堆積，導致燈條102的溫度過高，即使將金屬散熱片106與背板108的接觸面積變大仍有熱量傳導不易而產生熱堆積的問題，因為燈條102傳導過來的熱會卡在金屬散熱片106的高度h過窄的位置處。If the backlight module accumulates too much heat, the temperature of the light-emitting element locally rises, resulting in a decrease in luminous efficiency, chromaticity shift, and lifetime decay. Referring to FIG. 4 , the heat dissipation path of the conventional backlight module 100 is mainly transmitted to the metal heat sink 106 through the light strip 102 , and the partial heat is absorbed through the metal heat sink 106 to conduct part of the heat to the back plate 108 . And exchange heat with the outside cold air. However, in order to increase the light mixing distance of the light bar 102, it is necessary to reduce the thickness d of the metal heat sink 106 that abuts against the back surface 102a of the light bar 102 (the side of the back light guide plate 104), so that the heat resistance is excessively large and heat accumulation occurs. This causes the temperature of the light bar 102 to be too high. In addition, for the thinning requirement of the backlight module 100, the overall thickness of the backlight module 100 needs to be reduced, for example, the height h of the metal heat sink 106 under the light bar 102 is lowered, so that the thermal resistance is too large, and heat conduction is not easy. The heat accumulation causes the temperature of the light bar 102 to be too high. Even if the contact area between the metal heat sink 106 and the back plate 108 is increased, heat conduction is difficult and heat accumulation is caused because the heat transmitted by the light bar 102 is stuck. The height h of the metal fins 106 is too narrow.

請參考圖1，本發明一實施例的背光模組10包括一導光板12、一燈條14、一第一導熱片16、一第二導熱片18以及一背板22。導光板12具有一入光面12a，燈條14設置於鄰近入光面12a位置處，且燈條14具有面向入光面12a的一第一側面14a及相對於第一側面14a的一第二側面14b。換句話說，第二側面14b背向入光面12a。第一導熱片16具有一基部16a及與基部16a夾一角度的一彎折部16b，第一導熱片16的基部16a抵靠於背板22，且第一導熱片16的彎折部16b抵靠燈條14的第二側面14b。第二導熱片18疊置於第一導熱片16上且抵靠燈條14的第一側面14a。第二導熱片18具有一基部18a及與基部18a夾一角度的一彎折部18b，第二導熱片18的基部18a抵靠第一導熱片16，且第二導熱片18的彎折部18b抵靠燈條14的第一側面14a。燈條14例如可為一發光二極體燈條(LED light bar)且具有至少一發光二極體141。Referring to FIG. 1 , a backlight module 10 according to an embodiment of the invention includes a light guide plate 12 , a light bar 14 , a first heat conductive sheet 16 , a second heat conductive sheet 18 , and a back sheet 22 . The light guide plate 12 has a light incident surface 12a. The light bar 14 is disposed adjacent to the light incident surface 12a, and the light bar 14 has a first side surface 14a facing the light incident surface 12a and a second surface opposite to the first side surface 14a. Side 14b. In other words, the second side 14b faces away from the light incident surface 12a. The first heat conducting sheet 16 has a base portion 16a and a bent portion 16b at an angle with the base portion 16a. The base portion 16a of the first heat conducting sheet 16 abuts against the backing plate 22, and the bent portion 16b of the first heat conducting sheet 16 abuts. It depends on the second side 14b of the light bar 14. The second thermally conductive sheet 18 is superposed on the first thermally conductive sheet 16 and abuts against the first side 14a of the light bar 14. The second heat conducting sheet 18 has a base portion 18a and a bent portion 18b at an angle with the base portion 18a. The base portion 18a of the second heat conducting sheet 18 abuts against the first heat conducting sheet 16, and the bent portion 18b of the second heat conducting sheet 18 Abuts the first side 14a of the light bar 14. The light bar 14 can be, for example, an LED light bar and has at least one light-emitting diode 141.
圖1所示的箭頭方向指出燈條14的主要散熱途徑，燈條14產生的熱可透過彼此堆疊的第一導熱片16及第二導熱片18有效並迅速傳導至背板22而與外界冷空氣進行熱交換。因燈條14的第一側面14a及第二側面14b分別接觸第二導熱片18及第一導熱片16，故熱可從燈條14的第一側面14a及第二側面14b雙向排出，增加散熱途徑並提高散熱效果。再者，因第一導熱片16及第二導熱片18係利用堆疊方式構成一複合散熱結構，故第一導熱片16及第二導熱片18的材質可分別選擇，且第一導熱片16及第二導熱片18的至少其中之一亦可由不同材質的複數區段組合構成。如圖2所示，舉例而言，第二導熱片18可由第一區段181、第二區段182及第三區段183組合構成，因第二導熱片18的中間部分通常溫度較高，故中間的第二區段182例如可用熱傳導係數相對較高的銅材，兩側的第一區段181及第三區段183例如可用材質較輕且成本較低的鋁材，使散熱均勻，降低導熱片受熱不均導致熱應力而產生形變。亦即，上述實施例利用堆疊導熱片或組合導熱片區段的方式，可針對實際散熱需求、成本考量或其他因素使一導熱結構的不同區塊具有不同的材質。The direction of the arrow shown in FIG. 1 indicates the main heat dissipation path of the light bar 14. The heat generated by the light bar 14 can be effectively transmitted to the back plate 22 through the first heat conducting sheet 16 and the second heat conducting sheet 18 stacked on each other to be cold. The air is heat exchanged. Since the first side surface 14a and the second side surface 14b of the light bar 14 respectively contact the second heat conducting sheet 18 and the first heat conducting sheet 16, heat can be bidirectionally discharged from the first side surface 14a and the second side surface 14b of the light strip 14 to increase heat dissipation. Ways and improve heat dissipation. Furthermore, since the first heat conducting sheet 16 and the second heat conducting sheet 18 form a composite heat dissipating structure by stacking, the materials of the first heat conducting sheet 16 and the second heat conducting sheet 18 can be respectively selected, and the first heat conducting sheet 16 and At least one of the second thermally conductive sheets 18 may also be composed of a combination of a plurality of sections of different materials. As shown in FIG. 2, for example, the second heat conducting sheet 18 may be composed of a combination of the first section 181, the second section 182, and the third section 183, because the middle portion of the second heat conducting sheet 18 is generally at a higher temperature. Therefore, in the middle second section 182, for example, a copper material having a relatively high heat transfer coefficient can be used, and the first section 181 and the third section 183 on both sides can be made of, for example, a lighter material and a lower cost aluminum material, so that heat dissipation is uniform. Reducing the unevenness of the heat transfer sheet causes thermal stress to cause deformation. That is, the above embodiment utilizes the method of stacking the thermal conductive sheets or combining the thermal conductive sheet segments, and different blocks of a heat conducting structure may have different materials for actual heat dissipation requirements, cost considerations, or other factors.
比較圖3A及圖3B可知，如圖3A所示，習知設計欲形成背板108與燈條102間的導熱結構(金屬散熱片106)時，因導熱結構於不同區域需具有不同厚度，故通常利用鋁擠一體成型的方式製造，然而鋁擠成形的製造方式材料選擇單一而不具彈性且成本較高。反之如圖3B所示，依上述實施例之設計，利用至少堆疊第一導熱片16及第二導熱片18形成導熱結構的方式，第一導熱片16及第二導熱片18可經模具沖壓分別成型再進行組合，故可提供較佳的材質選擇彈性且成本較低。3A and 3B, as shown in FIG. 3A, when a heat-conducting structure (metal heat sink 106) between the back plate 108 and the light bar 102 is conventionally designed, the heat-conducting structure needs to have different thicknesses in different regions. It is usually manufactured by means of aluminum extrusion molding, however, the aluminum extrusion molding material is selected to be single, not elastic, and high in cost. On the other hand, as shown in FIG. 3B, according to the design of the above embodiment, the first heat conducting sheet 16 and the second heat conducting sheet 18 are formed by stamping the first heat conducting sheet 16 and the second heat conducting sheet 18, respectively. Forming and then combining, it can provide better material selection flexibility and lower cost.
依本發明實施例的設計，第二導熱片18一端抵靠燈條，而第二導熱片18的形態完全不限定，例如第二導熱片18的一端可彎折形成一彎折部18b(圖1所示)，亦可不形成彎折部(圖3B所示)。再者，於一實施例中，可利用例如螺絲的鎖固件32將第一導熱片16及第二導熱片18鎖固於背板22上(圖1所示)。According to the design of the embodiment of the present invention, one end of the second thermal conductive sheet 18 abuts against the light bar, and the shape of the second thermal conductive sheet 18 is not limited. For example, one end of the second thermal conductive sheet 18 can be bent to form a bent portion 18b (Fig. 1)), or a bent portion (shown in FIG. 3B) may not be formed. Moreover, in an embodiment, the first thermal conductive sheet 16 and the second thermal conductive sheet 18 can be locked to the backing plate 22 by using a fastener 32 such as a screw (shown in FIG. 1).
綜上所述，本發明的實施例的背光模組至少具有下列其中一個優點：因燈條14的第一側面14a及第二側面14b分別接觸第二導熱片18及第一導熱片16，故熱可從燈條14的第一側面14a及第二側面14b雙向排出，增加散熱途徑並提高散熱效果及熱均性。再者，利用堆疊第一導熱片16及第二導熱片18，或者第一導熱片16及第二導熱片18的至少其中之一由不同材質的複數區段組合構成，使散熱均勻，降低金屬受熱不均導致熱應力而產生形變，可針對實際散熱需求、成本考量或其他因素使一導熱結構的不同區塊具有不同的材質，且各個導熱片可經模具沖壓分別成形製造再進行組合，故可提供較佳的材質選擇彈性且成本較低。另外，進行板金沖壓處理的第一導熱片16及第二導熱片18具有較佳的結構強度，故第一導熱片16及第二導熱片18不僅可提高散熱效果也可增強背光模組整體的結構強度。In summary, the backlight module of the embodiment of the present invention has at least one of the following advantages: since the first side 14a and the second side 14b of the light bar 14 respectively contact the second heat conducting sheet 18 and the first heat conducting sheet 16, The heat can be discharged bidirectionally from the first side 14a and the second side 14b of the light bar 14, increasing the heat dissipation path and improving the heat dissipation effect and heat uniformity. Furthermore, by stacking the first thermal conductive sheet 16 and the second thermal conductive sheet 18, or at least one of the first thermal conductive sheet 16 and the second thermal conductive sheet 18 is composed of a plurality of different sections of different materials to uniformly dissipate heat and reduce metal. The heat is unevenly caused to cause deformation by thermal stress, and different blocks of a heat-conducting structure may have different materials for actual heat dissipation requirements, cost considerations, or other factors, and each of the heat-conducting sheets may be separately formed by die stamping and then combined. It provides better material selection flexibility and lower cost. In addition, the first thermal conductive sheet 16 and the second thermal conductive sheet 18 which are subjected to the sheet metal stamping treatment have better structural strength, so that the first thermal conductive sheet 16 and the second thermal conductive sheet 18 can not only improve the heat dissipation effect but also enhance the overall backlight module. Structural strength.
