具体实施方式 Detailed ways

[0015] 下面参照附图对本发明做进一步的说明。 [0015] The following figures further illustrate the invention reference.

[0016] 参考图1及图2,本发明提供一种用于LED灯箱的光源模组,包括透光前面板10及多个光源单元20(图1中所示以包含3个单元为例);其中,所述光源单元20,包括槽型金属板21、LED基板22及金属底座23 ;所述基板22的正面具有多个LED灯珠221的安装位置;所述槽型金属板21具有一平坦的底部,所述底部具有多个与所述LED灯珠安装位置相对应的孔位,以容纳所述LED灯珠穿设;所述基板22的正面根据所述孔位与所述槽型金属板21的底部的背面接合;所述金属底座23具有一平坦的顶部,所述顶部的正面与所述基板22的背面接合;所述槽型金属板21的槽口方向朝向所述前面板10。 [0016] Referring to FIG. 1 and FIG. 2, the present invention provides for a LED light source module box, comprising a front panel 10 and the plurality of light transmissive light source unit 20 (shown in Figure 1 to comprise three units, for example) ; wherein the light source unit 20, comprising a slotted metal plate 21, LED substrate 22 and the metal base 23; a front surface of the substrate 22 having a plurality of mounting position of the LED lamp 221; and the metal plate 21 having a groove flat bottom, said bottom having a plurality of holes with the LED bead mounting position corresponding to the LED lamps to accommodate penetrates; front surface of the substrate 22 in accordance with the holes of the groove bottom to engage the metal plate 21; the metal base 23 having a flat top, front and back surface of the top of the bonded substrate 22; the direction of the notch groove of the metal plate 21 toward the front panel 10.

[0017] 如图2所示,LED基板21优选为条形铝基板,其上具有多个LED灯珠(颗粒)221的安装位置。 [0017] As shown in FIG 2, LED substrate 21 is preferably strip-shaped aluminum plate having a mounting location 221 on which a plurality of LED lamps (particles).

[0018] 相应的,槽型金属板21的底部也呈条形,且宽度最好不小于条形铝基板的宽度,以便当条形铝基板的正面与槽型金属板21的底部的背面接合后,铝基板的热量可以最大面积的尽快传导至槽型金属板的底部,并进而通过整个槽型金属板进行散热。 [0018] Accordingly, the groove bottom of the metal plate 21 is also on the strip, and the width is preferably not less than the width of the strip-shaped aluminum plate, when the back surface for engaging a front strip at the bottom of the aluminum plate and the metal plate 21 of the groove after the heat conducting aluminum substrate may be the maximum area as soon as possible to the bottom of the groove of the metal plate, and thus heat dissipation through the entire slotted metal plate.

[0019] 条形铝基板22的背面通过与金属底座23的顶面的接合,又可以将铝基板背面的热量直接传导至金属底座进行散热,因此,同样,金属底座的顶部的宽度最好也是不小于条形铝基板的宽度,且与铝基板背面紧密接合。 [0019] By engaging the top surface of the metal base 23, and the back surface of the aluminum heat can be directly conducted to the metallic base plate back surface of the strip-shaped aluminum plate 22 for cooling, and therefore, similarly, the width of the top of the metal base is preferably not less than the width of the strip-shaped aluminum plate, and tightly bonded with the aluminum back plate.

[0020] 所述基板22的正面可以通过一导热粘合材料层与所述槽型金属板的底部的背面接合;所述基板22的背面也可以通过一导热粘合材料层与所述金属底座的顶部的正面接合,以增加连接紧密度,使热传导效率更高。 [0020] The front substrate 22 may be engaged with the back surface of the groove bottom of the metal plate by a thermally conductive adhesive material layer; back surface of the substrate 22 may be by a heat conductive adhesive material layer and the metal base engaging the top of the front, to increase the tightness of the connection, so that more efficient heat conduction. 当然,也可以采用压接等其他接合方式。 Of course, other crimping engagement may be employed.

[0021] 通过本发明上述实施例的结构设计,热量较高的LED铝基板通过正面和背面的同时散热,可以较快的将热量传导出去,而且散热面积也相应加大,较好的提高了散热效果。 [0021] By simultaneously dissipate heat through the front and back design of the present invention, the above-described embodiments, higher heat of the LED aluminum plate, can conduct heat away faster, and have also increased the heat dissipation area is preferably increased heat radiation.

[0022] 此外,由于将槽型金属板21、铝基板22、金属底座23整合为一个单独的光源单元20,因此,可以根据不同的尺寸要求,配合一个符合尺寸要求的前面板和多个符合照度要求的光源单元,组成一个可独立拆装的光源模组,再将多组光源模组紧密排列即可构成一个完整的灯箱光源系统,不仅现场装配更加方便灵活,而且也有利于维护,当个别LED灯珠发生故障时,只需要现场更换该LED灯珠所属的光源模组或光源单元即可。 [0022] Further, since the groove 21 of the metal plate, aluminum plate 22, the metal base 23 integrated into a single unit light source 20, and therefore, according to different size requirements, with a required dimension of the front panel and a plurality of compliance illumination requirements of the light source unit, the light source module composed of a separate removable, then multiple sets of closely arranged the light source module to form a complete system of light boxes, not only on-site assembly more convenient and flexible, but also help maintain, when when an individual LED lamp fails, only field-replaceable light source module or the light source unit to the LED lamp belongs. 而且,单一光源单元或光源模组的重量轻,尺寸小,便于搬运和安装,可以从灯箱的底部或侧面进入灯箱,适合于底开盖或侧开盖灯箱环境。 Further, the light source unit or a single light weight light source module, small size, ease of handling and installation, can enter the box from the bottom or side of the box, for opening the lid to the bottom open end or side of the lamp box. 同时,由于光源单元和光源模组都可以作成完整产品形态,不需要在灯箱工程现场进行安装,提高了现场施工效率。 At the same time, the light source unit and the light source module can be made complete product form, do not need to be installed in a lightbox project site, to improve the efficiency of the construction site.

[0023] 如图3所示,为根据本发明实施例所述的另一光源单元20的结构示意图,其中,槽型金属板21还具有沿所述底部两侧向斜上方延伸的两侧壁,且位于所述LED灯珠发出的有效直射光线范围之外,不会阻挡LED发出的直射光。 [0023] 3, it is a schematic view of another embodiment of the light source unit 20 according to the present invention, wherein the metal plate 21 also has a groove side walls along the sides of the bottom extending obliquely upward and positioned outside the effective range of the direct light emitted from said LED lamp, not block the direct light emitted by the LED. 而所述槽型金属板内表面可为反射面,以将LED侧向发出的余光以及从槽口处反射回来的光再反射出去,提高了光效。 The groove and the inner surface of the metal plate may be a reflection surface so as to laterally afterglow emitted LED light reflected from the notch, and the re-reflected back out to improve the light efficiency. 而在所述槽型金属板的两侧壁末端还可以分别具有一外翻边211,可加强槽型金属板侧壁的强度,而且可以使槽口处与前面板的背面接合的更加牢靠和严密。 In the side walls of the groove end of the metal plate may also have an outer flange 211, the metal plate can reinforce the strength of the side wall of the groove, but also the back surface of the front panel of the slot is more robust and respectively engaging tight.

[0024] 所述外翻边211可以与所述前面板平行,这样,可以在外翻边与前面板之间设置弹性材料,不仅可以保护面板免受金属材料的划损,而且可以进一步增加密封效果,使灰尘不易进入槽型金属板内部。 [0024] The outer flange 211 may be parallel with the front panel, so that, an elastic material may be provided between the outer flange and the front panel, not only to protect the panel from scratches metallic material, and the sealing effect can be further increased , so that dust does not easily enter the inside slotted metal plate.

[0025] 图1中所示的槽型金属板21与金属底座23之间未接合,而实际上,它们也是可以为相互连接的结构,以将热量在槽型金属板与金属底座之间平衡传导。 Slotted metal plate as shown in [0025] 121 in FIG. 23 is not engaged with the metal base, and in fact, may be a structure which is interconnected to the heat balance between the groove and the metal base plate conduction. 而连接结构可以有很多种,例如图3中所示的金属底座23包括相互连接的内框架232及外框架231,所述外框架231与所述槽型金属板21连接,所述内框架232通过平坦的顶部与所述基板22的背面接合,以传导基板22背面的热量。 And connection structure can have a variety, such as a metal base 23 shown in FIG. 3 includes an inner frame 232 and interconnected outer frame 231, the outer frame is connected to the groove 231 of the metal plate 21, the inner frame 232 through the back of the flat top substrate 22 bonded to the back surface of the heat-conducting substrate 22. 而在所述金属底座的顶部下方还可以具有一中空部233 (或也可以呈内凹部的形态),以容纳LED铝基板的电源或电路连线。 But below the top of the metal base may also have a hollow portion 233 (or can also be in the form of concave portion), or to receive the power supply circuit connecting LED aluminum plate. 外框架231还可以与铝基板22的侧面接合,将铝基板侧面的热量也传导出来,这样,铝基板22的正面、背面以及侧面都有金属材料接合,热散效率更佳。 The outer frame 231 may also be engaged with the side of the aluminum substrate 22, the heat conducting aluminum substrate side is also out, so that the front surface of the aluminum substrate 22, and the back side has a bonding metal material, better heat dispersion efficiency.

[0026] 前面板10可以与光源单元20之间有一段距离,以便LED灯珠发出的热量可以通过空气散播至槽型金属板外部,但这样则会导致密封效果不佳;另一种方案则是不留距离,将所述槽型金属板21的槽口抵靠于所述透光前面板10的背面,如此则可加强密封效果,灰尘不易进入槽型金属板内部,而由于槽型金属板本身的金属散热性能较好,而且还可以与金属底座相连,增大了散热面积,因此,可以实现散热与密封的综合效果。 [0026] The front panel and the light source unit 10 may have a distance between 20, so that heat emitted from the LED lamp can be spread to the outside of the metal plate through the air groove, but this will lead to poor sealing effect; another solution is distance is not left, the slot 21 of the metal plate against the rear surface groove to the front panel 10 is light-transmissive, so the sealing effect can be strengthened, dust easily enters the inside groove of the metal plate, since the groove and the metal preferably the metal heat dissipation board itself, but also connected with the base metal, the heat dissipation area is increased, and therefore, cooling effect can be achieved with a sealed integrated.

[0027] 如图4所示,本发明实施例所述光源模组还可以进一步包括上封边30及下封边40,分别与所述前面板10及光源单元20的上端部及下端部相连,通过螺钉或卡槽等连接固定方式,可以将所述槽型金属板21的槽口紧紧抵靠于所述前面板10的背面,并将所述槽型金属板21的上端部开口处和下端部开口处抵封。 [0027] As shown in FIG 4, the embodiment of the present invention, a light source module may further include an upper edge seal 30 and the lower edge sealing 40, are connected to the front panel lower portion and the upper portion 10 and the light source unit 20 by screws or the like fixedly connected to the card slot, the slot groove can be the metal plate 21 tightly against the back surface of the front panel 10, and the upper opening of the groove portion 21 of the metal plate and a lower portion in contact seal opening. 通过上封边30及下封边40,不仅可以强化固定前面板10与光源单元20,而且还可以将槽型金属板21的上下端部开口堵住,防止灰尘从端部开口处进入槽型金属板内部。 Edge 30 through the upper and lower edge sealing 40, can enhance not only the front panel 10 fixed to the light source unit 20, but also the upper and lower end portions of the groove of the metal plate 21 to block the opening to prevent dust from entering the groove from the end opening an internal metal plate. 当然,该端部开口处也可以单独使用堵封部件,而槽型金属板的槽口与前面板的抵靠也可以通过在灯箱内部的装配位置实现,但通过如图4所示的上下封边来实现则更加简便和牢固。 Of course, the opening end portion may be used alone, the dam member, the notch groove while abutting the metal plate on the front panel may be realized by the assembled position inside the box, but as shown by the vertical seal 4 shown in FIG. side to realize the more convenient and secure.

[0028] 此外,所述光源模组还可以包括至少一个横向支撑架50,位于所述光源单元20的下方,通过与所述前面板10及光源单元20相连接,可以将所述槽型金属板21的槽口更紧密的抵靠于所述前面板的背面,同时也对光源单元20起到了很好的支撑作用,防止其塌腰。 [0028] Furthermore, the light source module may further comprise at least one transverse support frame 50, located below the light source unit 20 through 20 is connected to the front panel and the light source unit 10 may be a metal groove notched plate 21 more closely against the rear surface of the front panel, but also on the light source unit 20 functions as a good support effect, prevent its gooseneck.

[0029] 如图5所示,为图4中的光源模组去掉下封边后的局部放大示意图,可明显看出光源单元20的横截面形状,也可以看出槽型金属板21底部的孔位,以容纳LED灯珠从对应孔位中穿出。 [0029] 5, the local in FIG. 4 is removed at the light source module Edge enlarged view, the light source unit apparent cross-sectional shape 20, it can be seen at the bottom of the groove 21 of the metal plate holes to accommodate the LED lamp from the corresponding holes in the piercing.

[0030] 如图6所示,为根据本发明的实施例所示的光源模组去掉下封边后的侧后向立体示意图,光源单元20的槽型金属板21的槽口抵靠着前面板10,并通过金属底座23与支撑架50相连接,而支撑架的边缘可通过螺钉或卡槽与前面板连接。 [0030] As shown in FIG 6, is removed at the lateral edge banding source module according to an embodiment of the present invention is shown in the perspective view, the light source unit notch groove 21 of the metal plate 20 abuts against the front panels 10 and 50 connected by a metal base 23 and the support frame, the supporting frame by screws or the edges may be connected with the front panel slot.

[0031] 如图7所示,为根据本发明实施例所述的光源模组的正视图,上封边30及下封边40将前面板10及光源单元20抵靠在一起,下方由支撑架50做进一步的加固。 [0031] 7, is a front view of the light source module according to an embodiment of the present invention, the edge seal 30 and the lower edge sealing 40 of the front panel 10 and the light source unit 20 abut against each other, supported by a downward frame 50 further reinforcement.

[0032] 如图8所示,根据本发明的实施例,所述前面板10可以具有多个间隔排列的透光部11和反光部12,所述透光部11与所述槽型金属板的槽口位置区域相对应,所述反光部12与所述槽口位置区域之外的区域相对应,也就是大致分布于相邻光源单元之间的区域,反光面朝向展示画面,将接收到的光线向画面展示方向反射。 [0032] As shown, according to an embodiment of the present invention, the front panel 10 may have a plurality of spaced light-transmissive portions 11 and 12, the groove 11 of the metal plate and the reflective portion of the light transmitting portion 8 the location of the notch region corresponding to the reflective portion 12 and the area other than the area corresponding to the location of the notch, is substantially distributed in the region between the adjacent unit light source, the reflective surface faces the presentation, the received the light reflected toward the direction of the screen display.

[0033] 所述透光部11可以是全透光的,也可以是半透光的,例如,如果前面板是玻璃,不做处理的部分即为全透光部,而如果将其正面对应区域表面打磨呈磨砂状,或者贴上各种半透光膜,则可以作为半透光部。 [0033] The light-transmissive portion 11 may be fully transparent, or may be semi-transparent, for example, if the front panel is a glass, not part of the whole process is the light-transmitting portion, and if it corresponds to the front side polished surface was frosted area, or plastered with a semitransparent film, it may be used as a semi-transmissive portion. 当然,半透光是相对于全透光和不透光来说的,并非是指透光率严格为50%的含义,实际上,用户可以根据需要选择不同的透光率。 Of course, the total light transmittance with respect to the semipermeable light and is opaque, and does not refer to a light transmittance of 50% strict meaning, in fact, the user can select different light transmittance according to need. 总之,所述透光部可以是形成于所述前面板上的条状半透光层,也可以是采用例如柔光板或奶白板之类的板材,其本身不需要处理即是半透光的材质。 In short, the light transmitting portion may be a semi-transmissive layer formed in stripes on the front panel, for example, may be employed as a diffuser plate or milky white plate or the like which itself does not need to process that is semi-transparent material.

[0034] 全透光的好处是LED的光线可以无阻碍的全部透过前面板透光部而发射出来,但缺点是光线如果太强则容易在展示画面100的相应位置形成亮区,而其他区域相应成为暗区,造成亮度不均匀,因此,光源单元与展示画面之间的距离不能太近,造成灯箱厚度加大。 [0034] The benefits of the total light transmittance is an LED light unhindered through all of the front panel and the light-transmitting portion is emitted, but the drawback is that if the light is too strong it is easy to position in the display screen 100 is formed corresponding to the bright area, while the other a dark region corresponding to region, resulting in non-uniform brightness, and therefore, the distance between the light source unit and the presentation can not be too close, resulting in increased thickness of the light box.

[0035] 而半透光部的处理则可以将LED发出的光线首先进行漫反射和折射处理,相当于是在槽型金属板内先进行了匀光,然后再照射出去,如光线201的光程所示,这样,从半透光部照射出去的光线都是较为均匀的,没有过强的光线,也就不会在画面上形成亮区和暗区,因此,灯箱的厚度可以变得较薄。 [0035] The processed semi-transparent portion of the light emitted by the LED may be first subjected to diffuse reflection and refraction process, corresponding to the groove in the first metal plate made uniform light and then irradiating out of the optical path as rays 201 as shown, so that the semi-transparent portion irradiated with light is out relatively uniform, not too strong light, it does not form a bright and dark areas on the screen, and therefore, the thickness of the box may become thinner .

[0036] 另一方面,由于LED发光角度的限制,其有效发光角度之外基本上是没有光线直射出去的,如光线202所示,基本上可认为是LED有效光线的边界光线,可以看出,不透光的反光部12是不会阻挡LED的有效直射光线的。 [0036] On the other hand, due to the limitation of the angle of LED light, other than the effective light-emitting angle is substantially no direct light out of the light 202 as shown, may be considered substantially valid boundary light from the LED light, it can be seen , opaque reflecting portion 12 is not an effective barrier LED direct sunlight. 但是,由于灯箱是一个二次反射系统,光源单元20发出的光线照射到展示画面100后,有部分光线透射出去,但仍有部分光线被反射回来,其中,有些被反射到透光部11的区域,通过槽型金属板的槽口照射到槽型金属板的反光内表面上被再次反射向展示画面,而有些则会直接照射到反光部12,经由本发明的反光部12再次反射回展示画面,如光线203的光程所示,很明显,从展示画面反射回来的光,经过较短的光程就又反射回展示画面,因此,通过反光部12,可以极大的增强光效。 However, since the box is a secondary reflected light illumination system, the light source unit 20 is emitted to the display screen 100, some light transmittance out, but there are still some light is reflected back, which is reflected to some of the light transmitting portion 11 area, the metal plate is irradiated to the groove by the notch groove of the metal plate is reflected toward the reflective display screen, and some will be directly irradiated on the surface of the reflective portion 12 again via the reflecting portion 12 of the present invention showing reflected back again screen, as shown in the optical path of the light 203, it is clear that the reflected light back from the presentation, through a short optical path and is reflected back on the display screen, and therefore, the reflective portion 12, light efficiency can be greatly enhanced. 一般来说,反光部12所对应的画面位置区域由于处于LED有效直射光线的边界区域,因此往往比正对LED灯珠的区域的亮度稍暗,但经过反光部反射的光线进行补光后,画面亮度则会显得更加均匀。 Generally, a screen 12 corresponding to the position of the region at the boundary region since the reflecting portion effective to direct light LED, it is often facing luminance area darker than the LED lamp, but after the light reflecting portion reflecting the light after the meeting, the screen brightness will be even more evenly.

[0037] 所示反光部可以是贴在前面板上的一层反光膜,或者是形成于所述前面板上的白漆层,而后者最为简单和经济。 [0037] FIG reflecting portion may be a layer of reflective film attached to the front panel, or formed on the front panel of white paint, which most simple and economical.

[0038] 由此可见,本发明通过槽型金属板底部的孔位,将LED灯珠穿设在槽型金属板内作为光源,但是将铝基板设置于槽型金属板的外部,降低了槽型金属板内的温度,同时,将铝基板夹设于槽型金属板的底部与金属底座的顶部之间,使其两面同时散热,进一步提高了散热效率。 [0038] Thus, the present invention is the bottom of the groove holes by a metal plate, the LED lamp as a light source disposed within the through groove of the metal plate, but the aluminum plate is provided on the outer groove of the metal plate, reducing the groove the temperature in the metal plate while the aluminum plate is sandwiched between the top and the bottom of the groove of the metal base of the metal plate, so that both sides simultaneous cooling, to further improve the heat dissipation efficiency. 此外,通过槽型金属板的槽口与前面板的扣合,形成较为密封的空间,防止了灰尘进入槽型金属板内沾染在LED灯珠上,而在清洁时,前面板上的灰尘也非常容易擦拭。 Further, by engaging the notch groove of the metal plate and the front panel, to form a more sealed space, prevents the dust into the slotted sheet metal contamination in the LED lamp, and in the cleaning, also on the front panel of dust very easy to clean. 而前面板通过透光部与反光部的设计,可以极大的提高光效以及画面的均匀性。 By designing the front panel and the light transmitting portion of the light reflecting portion, can greatly improve the efficiency and uniformity of the light screen.
