Description
本發明是有關於一種光源模組，且特別是有關於一種採用點光源作為發光元件的光源模組。The invention relates to a light source module, and in particular to a light source module using a point light source as a light-emitting element.
圖1是習知一種光源模組的局部立體剖面示意圖。請參照圖1，習知光源模組包括發光二極體光源10及光源固定架50。發光二極體光源10包括電路板11及配置於電路板11上的發光二極體12，而光源固定架50用以固定電路板11。更詳細地說，光源固定架50包括側壁51、頂部52及底部53，而電路板11設置於底部53上。此外，習知技術藉由金屬沖壓的方式於頂部52加工出凸向底部53的抵靠部52a，以將電路板11固定於抵靠部52a與底部51之間。1 is a partial, perspective, cross-sectional view of a conventional light source module. Referring to FIG. 1 , the conventional light source module includes a light emitting diode light source 10 and a light source fixing frame 50 . The light-emitting diode light source 10 includes a circuit board 11 and a light-emitting diode 12 disposed on the circuit board 11, and the light source holder 50 is used to fix the circuit board 11. In more detail, the light source holder 50 includes a side wall 51, a top portion 52, and a bottom portion 53, and the circuit board 11 is disposed on the bottom portion 53. In addition, the conventional technique processes the abutting portion 52a of the bottom portion 53 on the top portion 52 by means of metal stamping to fix the circuit board 11 between the abutting portion 52a and the bottom portion 51.
圖2是圖1之光源模組在組裝時的示意圖。請參照圖2，習知光源模組在組裝時需將電路板11沿著預定方向A1推入光源固定架50內，而為了使電路板11能被固定於抵靠部52a與底部53之間，抵靠部52a與底部53之間的間距G需等於電路板11的寬度W。在推動電路板11時，電路板11與底部53之間會留有間距，以使電路板11易於被推動。然而，此將導致電路板11在組裝時會撞到抵靠部52a之與底部53垂直的側邊54，導致電路板11無法被順利推入抵靠部52a與底部53之間。2 is a schematic view of the light source module of FIG. 1 assembled. Referring to FIG. 2, the conventional light source module needs to push the circuit board 11 into the light source holder 50 along the predetermined direction A1 during assembly, so that the circuit board 11 can be fixed between the abutting portion 52a and the bottom portion 53. The spacing G between the abutting portion 52a and the bottom portion 53 needs to be equal to the width W of the circuit board 11. When the circuit board 11 is pushed, a space is left between the circuit board 11 and the bottom portion 53 to make the circuit board 11 easy to be pushed. However, this will cause the circuit board 11 to collide with the side edges 54 of the abutment portion 52a that are perpendicular to the bottom portion 53 during assembly, resulting in the circuit board 11 not being smoothly pushed between the abutment portion 52a and the bottom portion 53.

為讓本發明之上述和其他目的、特徵和優點能更明顯易懂，下文特舉較佳實施例，並配合所附圖式，作詳細說明如下。The above and other objects, features and advantages of the present invention will become more <RTIgt;
圖3A與圖3B是本發明一實施例之光源模組的不同方向的側視示意圖。請參照圖3A與圖3B，本實施例之光源模組200包括燈罩210及線光源220。燈罩210具有底壁212、與底壁212相對的頂壁214、連接於底壁212與頂壁214之間的側壁216以及與側壁216相對的出光口218。底壁212、頂壁214、側壁216與出光口218之間形成容置空間S，且頂壁214與底壁212至少其中之一具有凸向容置空間S的至少一定位部219。在本實施例中，定位部219例如是設置於頂壁214，而定位部219的數量是以一個為例。此外，燈罩210的材質例如為金屬，而定位部219例如是經沖壓而成的擋片。3A and 3B are side elevational views showing different directions of a light source module according to an embodiment of the present invention. Referring to FIG. 3A and FIG. 3B , the light source module 200 of the embodiment includes a lamp cover 210 and a line light source 220 . The lamp cover 210 has a bottom wall 212, a top wall 214 opposite the bottom wall 212, a side wall 216 connected between the bottom wall 212 and the top wall 214, and a light exit opening 218 opposite the side wall 216. The accommodating space S is formed between the bottom wall 212, the top wall 214, the side wall 216 and the light exit opening 218, and at least one of the top wall 214 and the bottom wall 212 has at least one positioning portion 219 protruding toward the accommodating space S. In the present embodiment, the positioning portion 219 is disposed, for example, on the top wall 214, and the number of the positioning portions 219 is taken as an example. Further, the material of the globe 210 is, for example, metal, and the positioning portion 219 is, for example, a stamped sheet.
承上述，線光源220適於沿預定方向A2從容置空間S的入口端S1置入容置空間S內。線光源220包括基板222與至少一點光源224，而本實施例是以多個點光源224為例。這些點光源224例如是發光二極體或雷射二極體等，但不以此為限。基板222具有面對出光口218的承載面222a、面對頂壁214的第一側面222b以及面對底壁212的第二側面222c。點光源224配置於承載面222a。第一側面222b與第二側面222c至少其中之一設有對應至少一定位部219的至少一凸起部225。也就是說，凸起部225的數量是與定位部219的數量及位置相對應。在本實施例中，由於定位部219設置於燈罩210的頂壁214，所以凸起部225設置於第一側面222b。此外，相對應的定位部219與凸起部225適於彼此干涉。具體來說，頂壁214與底壁212之間的距離為D1，第一側面222b與第二側面222c之間的距離為D2，相對應的定位部219與凸起部225凸起的高度分別為H1與H2，且H1+H2例如是等於或略大於D1-D2。如此，在基板222組裝至定位時，相對應的定位部219與凸起部225能彼此干涉，進而使基板222能固定於定位部219與底壁212之間。In the above, the line light source 220 is adapted to be placed into the accommodating space S from the inlet end S1 of the accommodating space S in the predetermined direction A2. The line source 220 includes a substrate 222 and at least one point of light source 224. In this embodiment, a plurality of point sources 224 are taken as an example. The point light source 224 is, for example, a light emitting diode or a laser diode, but is not limited thereto. The substrate 222 has a bearing surface 222a facing the light exit opening 218, a first side surface 222b facing the top wall 214, and a second side surface 222c facing the bottom wall 212. The point light source 224 is disposed on the carrying surface 222a. At least one of the first side 222b and the second side 222c is provided with at least one protrusion 225 corresponding to at least one positioning portion 219. That is, the number of the convex portions 225 corresponds to the number and position of the positioning portions 219. In the present embodiment, since the positioning portion 219 is disposed on the top wall 214 of the lamp cover 210, the convex portion 225 is disposed on the first side surface 222b. Further, the corresponding positioning portion 219 and the convex portion 225 are adapted to interfere with each other. Specifically, the distance between the top wall 214 and the bottom wall 212 is D1, and the distance between the first side surface 222b and the second side surface 222c is D2, and the heights of the corresponding positioning portion 219 and the convex portion 225 are respectively raised. It is H1 and H2, and H1+H2 is, for example, equal to or slightly larger than D1-D2. As such, when the substrate 222 is assembled to the positioning, the corresponding positioning portion 219 and the protruding portion 225 can interfere with each other, thereby enabling the substrate 222 to be fixed between the positioning portion 219 and the bottom wall 212.
另外，相對應的定位部219與凸起部225至少其中之一具有導引結構，以在進行組裝時，藉由導引結構將基板222導引至定位。本實施例中，定位部219例如具有導引結構219a，此導引結構219a為定位部219的斜面。此外，凸起部225例如是呈半圓球狀，而此凸起部225的表面亦可作為導引結構225a。需說明的是，此處的半圓球狀係指凸起部225的形狀為一個圓球狀的一部份，並非限定凸起部225的形狀需為一個的圓球狀的一半。In addition, at least one of the corresponding positioning portion 219 and the convex portion 225 has a guiding structure to guide the substrate 222 to the positioning by the guiding structure when assembling. In the present embodiment, the positioning portion 219 has, for example, a guiding structure 219a which is a slope of the positioning portion 219. In addition, the convex portion 225 is, for example, a semi-spherical shape, and the surface of the convex portion 225 can also serve as the guiding structure 225a. It should be noted that the semi-spherical shape here means that the shape of the convex portion 225 is a spherical portion, and the shape of the convex portion 225 is not limited to a spherical half.
圖4是圖3B之光源模組在組裝時的示意圖。請參照圖3A至圖4，在組裝光源模組200時，係沿預定方向A2推動線光源220以使線光源220從容置空間S的入口端S1置入容置空間S內。由於定位部219與凸起部225分別設有導引結構219a、225a，當基板222的凸起部225碰觸到定位部219後，若沿預定方向A2持續推動基板222向左移動，則導引結構219a、225a可導引基板222向左下方移動至接觸到燈罩210的底壁212，直到定位部219與凸起部225互相卡固。因此，本實施例之光源模組200在組裝時，可輕易且精確地將基板222組裝至定位。4 is a schematic view of the light source module of FIG. 3B when assembled. Referring to FIG. 3A to FIG. 4 , when the light source module 200 is assembled, the line light source 220 is pushed in a predetermined direction A2 to place the line light source 220 into the accommodating space S from the inlet end S1 of the accommodating space S. Since the positioning portion 219 and the convex portion 225 are respectively provided with the guiding structures 219a, 225a, when the convex portion 225 of the substrate 222 touches the positioning portion 219, if the substrate 222 is continuously pushed to the left in the predetermined direction A2, the guiding The guiding structures 219a, 225a can guide the substrate 222 to move to the lower left to contact the bottom wall 212 of the lamp cover 210 until the positioning portion 219 and the boss portion 225 are locked to each other. Therefore, when the light source module 200 of the embodiment is assembled, the substrate 222 can be assembled to the positioning easily and accurately.
值得一提的是，在將基板222置入燈罩210的容置空間S之前，可先於基板222之與承載面222a相對的背面224d設置膠膜230，而此膠膜230之面向側壁216的表面例如貼有可撕除的非黏性膜。當基板222移至定位時，可撕除非黏性膜，以藉由膠膜230將基板222黏貼於燈罩210的側壁216。此外，燈罩210可設有止擋部217，以避免組裝人員在基板222組裝至定位後仍持續施力推動基板222，使基板222超出其預設位置。此止擋部217的位置是位於容置空間S之與入口端S1相對的末端S2。如此，當基板222組裝至定位後，基板222的一端可抵靠到止擋部217，進而防止基板222超出預設位置。在本實施例中，止擋部217例如是設置於燈罩210的底壁212，但在其他實施例中，止擋部217亦可設置於燈罩210的側壁216或頂壁214。It is to be noted that, before the substrate 222 is placed in the accommodating space S of the lamp cover 210, the film 230 may be disposed on the back surface 224d of the substrate 222 opposite to the bearing surface 222a, and the film 230 faces the side wall 216. The surface is, for example, provided with a peelable non-adhesive film. When the substrate 222 is moved to the position, the adhesive film can be peeled off to adhere the substrate 222 to the sidewall 216 of the lamp cover 210 by the adhesive film 230. In addition, the lamp cover 210 can be provided with a stop portion 217 to prevent the assembler from continuously pushing the substrate 222 after the substrate 222 is assembled to the position, so that the substrate 222 exceeds its preset position. The position of the stopper portion 217 is the end S2 of the accommodating space S opposite to the inlet end S1. As such, after the substrate 222 is assembled to the position, one end of the substrate 222 can abut against the stop portion 217, thereby preventing the substrate 222 from exceeding the preset position. In the present embodiment, the stop portion 217 is disposed on the bottom wall 212 of the lamp cover 210, but in other embodiments, the stop portion 217 may also be disposed on the side wall 216 or the top wall 214 of the lamp cover 210.
另外，在組裝時，組裝人員可經由容置空間S的兩端S1、S2調整基板222的位置，使移至定位的基板222能夠承靠在燈罩210的底壁212。然而，燈罩210或基板222在製造時難免會產生公差，當基板222的長度較長時，雖然基板222的兩端已承靠在底壁212，但基板222的中段與底壁212之間仍可能會有間隙。因此，可將凸起部225設置於基板222的中段，而定位部219亦配合凸起部225的位置。如此，可藉由凸起部225將基板222的中段下壓至抵靠到底壁212。In addition, at the time of assembly, the assembler can adjust the position of the substrate 222 via the both ends S1 and S2 of the accommodating space S, so that the substrate 222 moved to the positioning can bear against the bottom wall 212 of the globe 210. However, the lamp cover 210 or the substrate 222 inevitably has tolerances during manufacture. When the length of the substrate 222 is long, although both ends of the substrate 222 have been supported by the bottom wall 212, the middle portion of the substrate 222 and the bottom wall 212 are still There may be gaps. Therefore, the boss portion 225 can be disposed in the middle portion of the substrate 222, and the positioning portion 219 also fits the position of the boss portion 225. As such, the middle portion of the substrate 222 can be pressed down against the bottom wall 212 by the raised portion 225.
雖然上述之凸起部225與定位部219分別具有導引結構225a、219a，但在其他實施例中，可僅有凸起部225具有導引結構225a或是僅有定位部219具有導引結構219a。此外，本發明並不限定定位部219與凸起部225的數量。在圖5所示的另一實施例中，定位部219與凸起部225的數量可分別為多個，且定位部219凸起的高度沿著預定方向A2而逐漸變大，凸起部225凸起的高度沿著預定方向A2而逐漸變小。當基板222移至定位時，每一相對應的定位部219與凸起部225可互相干涉。Although the above-mentioned convex portion 225 and the positioning portion 219 have guiding structures 225a, 219a, respectively, in other embodiments, only the protruding portion 225 may have the guiding structure 225a or only the positioning portion 219 has the guiding structure. 219a. Further, the present invention does not limit the number of the positioning portion 219 and the boss portion 225.

The light source module 200a of the present embodiment further includes a light guide plate 240 disposed beside the lamp cover 210a, and the light-incident surface 242 of the light guide plate 240 and the light-emitting cover 210a are emitted from the light-emitting module 200a. Port 218 is opposite to receive the light provided by point source 224. The light guide plate 240 converts the light into a surface light source and causes the surface light source to exit from the light exit surface 244. In addition, the lamp cover 210a further includes a first holding portion 215 connected to the top wall 214 and a second holding portion 213 connected to the bottom wall 212. The first holding portion 215 and the second holding portion 213 are opposed to each other and extend inward to hold the light guide plate 240. In addition, the light source module 200 may further include a reflective sheet 250 disposed on the bottom surface 246 of the light guide plate 240 to reflect light to the light exit surface, thereby improving light utilization efficiency.

The point light source 224 can be aligned with the intermediate position of the light incident surface 242 of the light guide plate 240, thereby improving light utilization efficiency.
圖9是本發明另一實施例之光源模組的側視示意圖，而圖10是圖9中框架的定位部與基板的凸起部互相干涉的示意圖。請參照圖9與圖10，本實施例之光源模組300包括燈罩310、線光源320及框架360。燈罩310具有底壁312、與底壁312相對的頂壁314、連接於底壁312與頂壁314之間的側壁316以及與側壁316相對的出光口318。底壁312、頂壁314、側壁316與出光口318之間形成容置空間S，而頂壁314具有至少一開孔311。框架360包覆燈罩310的頂壁314與側壁316，框架360具有對應至少一開孔311的至少一定位部362。也就是說，定位部362的數量與位置與開孔311的數量與位置相對應。在本實施例中，定位部362與開孔311的數量分別以一個為例。此外，定位部362經由對應的開孔311而伸入容置空間S內。線光源320適於沿預定方向A2從容置空間S的入口端(圖未示)置入容置空間S內，此入口端例如是位於圖10之燈罩310的右側方向。線光源320包括基板322與至少一點光源324。基板322具有面對出光口318的承載面322a、面對頂壁314的第一側面322b以及面對底壁312的第二側面322c。點光源324配置於承載面322a。第一側面322b設有對應至少一定位部362的至少一凸起部325。也就是說，定位部362的數量及位置與凸起部325的數量及位置相對應。相對應的定位部362與凸起部325適於彼此干涉。具體來說，頂壁314與底壁312之間的距離為D1，第一側面322b與第二側面322c之間的距離為D2，相對應的定位部362與凸起部325在容置空間S內的高度分別為H1與H2，且H1+H2例如是等於或略大於D1-D2。如此，在基板322組裝至定位時，相對應的定位部362與凸起部325能彼此干涉，進而使基板322能固定於定位部362與凸起部325之間。9 is a side elevational view of a light source module according to another embodiment of the present invention, and FIG. 10 is a schematic view of the positioning portion of the frame of FIG. 9 and the convex portion of the substrate interfere with each other. Referring to FIG. 9 and FIG. 10 , the light source module 300 of the embodiment includes a lamp cover 310 , a line light source 320 , and a frame 360 . The lampshade 310 has a bottom wall 312, a top wall 314 opposite the bottom wall 312, a side wall 316 connected between the bottom wall 312 and the top wall 314, and a light exit 318 opposite the side wall 316. The bottom wall 312, the top wall 314, the side wall 316 and the light exit opening 318 form an accommodation space S, and the top wall 314 has at least one opening 311. The frame 360 encloses the top wall 314 and the side wall 316 of the lamp cover 310. The frame 360 has at least one positioning portion 362 corresponding to at least one opening 311. That is, the number and position of the positioning portions 362 correspond to the number and position of the openings 311. In this embodiment, the number of the positioning portion 362 and the opening 311 are respectively taken as an example. In addition, the positioning portion 362 extends into the accommodating space S via the corresponding opening 311. The line light source 320 is adapted to be placed in the accommodating space S from the inlet end (not shown) of the accommodating space S in a predetermined direction A2, which is, for example, in the right direction of the lamp cover 310 of FIG. Line source 320 includes a substrate 322 and at least one point of light source 324. The substrate 322 has a bearing surface 322a facing the light exit 318, a first side 322b facing the top wall 314, and a second side 322c facing the bottom wall 312. The point light source 324 is disposed on the carrying surface 322a. The first side surface 322b is provided with at least one convex portion 325 corresponding to at least one positioning portion 362. That is, the number and position of the positioning portions 362 correspond to the number and position of the bosses 325. The corresponding positioning portion 362 and the raised portion 325 are adapted to interfere with each other. Specifically, the distance between the top wall 314 and the bottom wall 312 is D1, the distance between the first side surface 322b and the second side surface 322c is D2, and the corresponding positioning portion 362 and the convex portion 325 are in the accommodating space S. The heights inside are H1 and H2, respectively, and H1+H2 is, for example, equal to or slightly larger than D1-D2. As such, when the substrate 322 is assembled to the positioning, the corresponding positioning portion 362 and the convex portion 325 can interfere with each other, thereby enabling the substrate 322 to be fixed between the positioning portion 362 and the convex portion 325.
另外，與上述之光源模組200相似，相對應的定位部362與凸起部325至少其中之一具有導引結構，以在進行組裝時，藉由導引結構將基板322導引至定位。本實施例中，定位部362例如為柱體，而定位部362的導引結構362a例如是柱體的曲面。在另一實施例中，導引結構362a亦可為斜面或其他具有導引功能的表面。此外，凸起部325例如呈圓弧柱狀，而此凸起部325的表面亦可作為導引結構325a。在其他實施例中，凸起部的形狀亦可為圖6所示之立體梯形狀或其他合適的形狀。另外，在本實施例中雖然定位部362與凸起部325分別具有導引結構362a、325a，但在其他實施例中，可僅有定位部362具有導引結構362a或僅有凸起部325具有導引結構325a。In addition, similar to the light source module 200 described above, at least one of the corresponding positioning portion 362 and the convex portion 325 has a guiding structure for guiding the substrate 322 to the positioning by the guiding structure during assembly. In this embodiment, the positioning portion 362 is, for example, a cylinder, and the guiding structure 362a of the positioning portion 362 is, for example, a curved surface of the cylinder. In another embodiment, the guiding structure 362a can also be a bevel or other surface having a guiding function. In addition, the convex portion 325 has a circular arc shape, for example, and the surface of the convex portion 325 can also serve as the guiding structure 325a. In other embodiments, the shape of the raised portion may also be a three-dimensional ladder shape as shown in FIG. 6 or other suitable shape. In addition, in the present embodiment, although the positioning portion 362 and the convex portion 325 have guiding structures 362a, 325a, respectively, in other embodiments, only the positioning portion 362 may have the guiding structure 362a or only the convex portion 325. There is a guiding structure 325a.
與上述之光源模組200相似，由於本實施例之光源模組300的定位部362與凸起部325分別設有導引結構362a、325a，在將基板322推動至定位時，導引結構362a、325a可導引基板322移動至接觸到燈罩310的底壁312，直到定位部362與凸起部325互相卡固。因此，本實施例之光源模組300在組裝時，可輕易且精確地將基板322組裝至定位。Similar to the above-mentioned light source module 200, since the positioning portion 362 and the convex portion 325 of the light source module 300 of the present embodiment are respectively provided with guiding structures 362a, 325a, when guiding the substrate 322 to the positioning, the guiding structure 362a 325a can guide the substrate 322 to move to contact the bottom wall 312 of the lamp cover 310 until the positioning portion 362 and the boss portion 325 are locked to each other. Therefore, when the light source module 300 of the embodiment is assembled, the substrate 322 can be assembled to the positioning easily and accurately.
此外，與上述之光源模組200相似，本實施例之光源模組300的燈罩310可設有止擋部(圖未示)，且在基板322移至定位時可藉由膠膜330將基板322黏貼於燈罩310的側壁316。關於止擋部的位置與功用以及膠膜330的使用方法與上述實施例相似，在此將不再重述。In addition, similar to the light source module 200, the lamp cover 310 of the light source module 300 of the present embodiment may be provided with a stopper (not shown), and the substrate may be pressed by the adhesive film 330 when the substrate 322 is moved to the positioning. 322 is adhered to the side wall 316 of the lamp cover 310. The position and function of the stopper and the method of using the film 330 are similar to those of the above embodiment, and will not be repeated here.
另外，與圖8之光源模組200a相似，光源模組300可更包括配置於燈罩310旁的導光板340，且導光板340之入光面342與燈罩310之出光口318相對。燈罩310可更包括與頂壁314連接的第一挾持部315，以及與底壁312連接的第二挾持部313，且第一挾持部315與第二挾持部315彼此相對並向內延伸以挾持導光板340。In addition, similar to the light source module 200a of FIG. 8 , the light source module 300 may further include a light guide plate 340 disposed beside the lamp cover 310 , and the light incident surface 342 of the light guide plate 340 is opposite to the light exit opening 318 of the lamp cover 310 . The lamp cover 310 may further include a first clamping portion 315 connected to the top wall 314 and a second clamping portion 313 connected to the bottom wall 312, and the first clamping portion 315 and the second clamping portion 315 are opposite to each other and extend inwardly to hold Light guide plate 340.
與圖5相似，在另一實施例中，光源模組的定位部362與凸起部325的數量可分別為多個，且定位部362凸起的高度沿著預定方向A2而逐漸變大，凸起部325凸起的高度沿著預定方向A2而逐漸變小。由於多個定位部362與多個凸起部325的具體結構可參照圖5而推得，故在此不另配合圖式說明。Similar to FIG. 5, in another embodiment, the number of the positioning portion 362 and the protrusion portion 325 of the light source module may be multiple, and the height of the protrusion of the positioning portion 362 gradually increases along the predetermined direction A2. The height of the projection 325 is gradually reduced along the predetermined direction A2. Since the specific structure of the plurality of positioning portions 362 and the plurality of convex portions 325 can be derived with reference to FIG. 5, the drawings will not be described herein.
綜上所述，本發明的光源模組因設有相對應的定位部與凸起部，且相對應的定位部與凸起部至少其中之一具有導引結構，所以在將基板推入燈罩時，可藉由導引結構將基板導引至定位。因此，本發明的光源模組具有易於精確組裝的優點。In summary, the light source module of the present invention has a corresponding positioning portion and a convex portion, and at least one of the corresponding positioning portion and the convex portion has a guiding structure, so that the substrate is pushed into the lamp cover. The substrate can be guided to the position by the guiding structure. Therefore, the light source module of the present invention has the advantage of being easy to assemble accurately.
