嵌合於接頭主體102的凹槽102c，使得上蓋114a與下蓋 114b可相對於接頭主體1〇2進行轉動。 在第1A至第1D圖所示之實施例中，電路板106係固 接在第二容設空間114c中，其中電路板106可接合在上蓋 114a或下蓋iHb上。此外’如第1D圖所示，電路板106 更具有相對第一表面106a與第二表面106b，且電路板106 7 M412304 更利用以下即將說明之導線120電性連接至接頭主體i〇2 之第一端102a，藉以將電源傳遞至以下即將說明之LED晶 片 108。 在第1A至第1D圖所示之實施例中，LED光源模組 100包含6個LED晶片108。此些LED晶片108係電性連 接在電路板106的第一表面106a上，利用此些LED晶片 108提供LED光源模組100所需之光源。而LED晶片108 提供之光源係由下蓋114b之出光孔ll4d透射至LED光源 φ 模組100之外的空間。此外，LED光源模組100所包含之 LED晶片108之數量並不以本實施例為限，在其他實施例 中’ LED晶片108之數量可根據所需之光源強度（照度)加 以調整。 在本實施例中，如第1D圖所示，LED光源模組1〇〇 更包含二導線120，此二導線120係係容射在第一容設空 間102b以及第二容設空間114c中。此些導線120電性連 接電路板106與接頭主體102之第一端102a，使得上蓋U4a • 與下蓋H4b能相對於接頭主體1〇2進行轉動。在特定之實 ' 施例中’此些導線120為軟性可扭曲之導線，藉此使得上 蓋114a與下蓋114b能更加順利地相對於接頭主體1〇2進 行轉動。此外，導線120之數量可根據不同之功能需求加 以調整，而不侷限在本實施例之數量。 請參照第IB、ID、1E及1F圖，其中第1E圖及第if 圖係分別繪示第1A至1D圖中接頭主體之局部立體示意圖 以及第1A至1D圖中外蓋之局部立體示意圖。在本實施例 中’外蓋114所包含之上蓋114a及下蓋114b可藉由螺絲、 8 M412304 螺絲鎖附孔、卡固結構或卡合結構等結構而立相接合，其 中上蓋114a及下蓋U4b的接合為此技術領域所慣用之手 段，故不在此加以詳述說明。如第1D至1F圖所示，接頭 主體102更包含第一凸出部。此第一凸出部i〇2ci係 設置在接頭主體102之第二端1〇2f，且當外蓋114(上蓋 11如與下蓋114b)與接頭主體102互相嵌合時，第一凸出 部i〇2d朝上蓋U4a與下蓋114b形成之第二容設空間114c 延伸。而下蓋114b包含第二凸出部U4g，此第二凸出部 • 114g係鄰設在上述開口部旁。當上蓋114a與下蓋114b 相對於接頭主體102進行轉動時，由於第一凸出部1〇2(1與 第二凸出部114g的互相干涉，使得上蓋馳與下蓋mb 無f目對於接頭主體102進行一角度的轉動，而此角度大 於於0度，且小於360度。在特定實施例中，第一凸出 部_與第二凸出部叫之幾何形狀、結構與設置位置 可具有與本實施例不同之設計方式，而不以本實施例為 限，例如第二凸出部114g亦可包含於上蓋114&。 _ π參照第1D至1F圖，接頭主體1〇2之凹槽1〇2c中 具有另一第一凸出部102e。而上蓋114a與下蓋U4b形成 之開口部114f之週邊係實質為一圓形，此開口部U4f包含 與上述第二凸出部114g相異之多個第二凸出部u4h，其中 每個第二凸出部114h均朝上述圓形之圓心延伸且等距地 設置於開口部114f。在本實施例中，第二凸出部u4h之結 構係實質等同於常見之齒輪結構’但第二凸出部114h之結 構並不侷限在本實施例所示之結構。第一凸出部l〇2e係用 來與每個第二凸出部114h干涉，亦即當上蓋114a與下蓋 9 M412304 114b與接頭主體1〇2接合時，第一凸出部1〇2e係與多個第 二凸出部114h其中一者接觸。當上蓋114a與下蓋U4b相 對於接頭主體102進行轉動時，第一凸出部i〇2e與第二凸 出部114h的干涉，使得上蓋114a與下蓋114b以一特定角 度相對於接頭主體102進行步進轉動，亦即外蓋114相對 於接頭主體102轉動時，會受到上述干涉之阻力的影響， 故為施加較大之扭力才能使外蓋114相對於接頭主體1〇2 進行轉動。藉著上述之設計，可使得調整好的光源照射方 鲁向不會輕易地產生變化。 在第1A至1F所示之實施例中’為了將led晶片108 所產生之光源均勻化，LED光源模組1〇〇更包含有如第1B 及第ID所示之擴散膜118。將擴散膜118固設於第二容設 空間114c中，且鄰設在發光二極體晶片旁，當led 晶片108所產生之光源經過擴散膜118之後，即可得到更 加均勻的出射光。 此外，一般所採用之LED晶片岣具有一主要出光面， φ 而由此主要出光面的法線（垂直出光面的直線）朝兩側之特 疋張角（例如60度）所形成之圓錐範園，即為包含led晶片 產生之所有光源的範圍。然而’由於某些較大的角度範圍 内（例如50度至60度）之光源無法有效的投射至所欲照明 之範圍’因此造成了光源的浪費。故為了更有效率地利用 LED晶片108所產生的光源’ LED光源模組1〇〇更包含反 射體110’如第1B以及第1D所τρ：，反射辦】丨〇将营曾為 一環狀艘，環設在電路板!。6之第：二ί

模組112係設置在電路板106之第二表面l〇6b上。然而， 散熱模組112之幾何結構、設置位置與設置方式，並不以 本實施例為限，熟悉此技藝者當可根據LED光源模組1〇〇 之散熱需求加以變化。 此外，如第1D圖所示，上述之反射體11〇、擴散膜Π8 以及散熱模組112均容設於上蓋114a與下蓋114b所形成 之第二容設空間114c之中。 另外，如第1B及第1C圖所示，下蓋114b更包含透

For example, the second protrusion 114g may be included in the upper cover 114 & _ π refers to the 1D to 1F diagram, the groove of the joint body 1〇2 There is another first protruding portion 102e in the 1〇2c. The periphery of the opening 114f formed by the upper cover 114a and the lower cover U4b is substantially circular, and the opening U4f is different from the second protruding portion 114g. a plurality of second protrusions u4h, wherein each of the second protrusions 114h extends toward the center of the circle and is equidistantly disposed in the opening 114f. In this embodiment, the second protrusion u4h The structure is substantially equivalent to the common gear structure 'but the structure of the second projection 114h and The structure is limited to the structure shown in this embodiment. The first protrusions 〇2e are used to interfere with each of the second protrusions 114h, that is, when the upper cover 114a and the lower cover 9 M412304 114b are engaged with the joint body 1〇2. The first protruding portion 1〇2e is in contact with one of the plurality of second protruding portions 114h. When the upper cover 114a and the lower cover U4b are rotated relative to the joint main body 102, the first protruding portion i〇2e and The interference of the second protruding portion 114h causes the upper cover 114a and the lower cover 114b to rotate stepwise relative to the joint main body 102 at a specific angle, that is, when the outer cover 114 rotates relative to the joint main body 102, the interference of the interference is received. Therefore, in order to apply a large torque, the outer cover 114 can be rotated relative to the joint main body 1〇2. With the above design, the adjusted light source illumination direction can not be easily changed. In the embodiment shown in FIG. 1F, in order to homogenize the light source generated by the LED chip 108, the LED light source module 1 further includes a diffusion film 118 as shown in FIGS. 1B and ID. The diffusion film 118 is fixed to the diffusion film 118. The second accommodation space 114c is adjacent to the light-emitting diode Next to the film, when the light source generated by the LED wafer 108 passes through the diffusion film 118, a more uniform light can be obtained. In addition, the LED chip used generally has a main light-emitting surface, φ, and thus the main light-emitting surface. The cone formed by the line (the straight line of the vertical exit surface) toward the characteristic opening angle of the two sides (for example, 60 degrees) is the range of all the light sources generated by the LED wafer. However, due to some large angles A light source (eg, 50 degrees to 60 degrees) cannot be effectively projected into the desired range of illumination', thus causing waste of the light source. Therefore, in order to more efficiently utilize the light source generated by the LED chip 108, the LED light source module 1 further includes the reflector 110' such as the 1st and the 1st τρ:, and the reflection will be a ring. The ship is set on the circuit board! 6th: 2 ί to reflect the light source generated by the LED chip 108. In a particular embodiment, the geometry of the M412304 reflector 110 is not limited to this embodiment, and only the reflector 110 needs to be looped around the first surface iOh of the circuit board 106. In addition, since the LED chip has a small size and high brightness, the LED light source module using the LED chip usually has a problem that heat dissipation is not easy. In order to solve the heat dissipation problem described above, the LED light source module 100 further includes a heat dissipation module 112 as shown in FIGS. 1B and 1D, wherein the heat dissipation module 112 is disposed on the second surface 106b of the circuit board 106. However, the geometry, arrangement position and arrangement of the heat dissipation module 112 are not limited to the embodiment, and those skilled in the art can change according to the heat dissipation requirements of the LED light source module 1〇〇. Further, as shown in Fig. 1D, the reflector 11, the diffusion film 8 and the heat dissipation module 112 are accommodated in the second accommodation space 114c formed by the upper cover 114a and the lower cover 114b. In addition, as shown in FIG. 1B and FIG. 1C, the lower cover 114b further includes a transparent protective plate 116, and is fixed to the lower cover 114b and covers the range of the light-emitting hole 114d, so as to prevent the foreign object from being damaged by the light-emitting hole 114d. The circuit board 106 in the outer cover 114 and the LED chip 1〇8. Furthermore, in order to further enhance the heat dissipation performance of the LED light source module 100, as shown in FIGS. 1A to 1D, the upper cover U4a or the lower cover 114b has a plurality of heat dissipation holes 114e, and the second accommodation space 114c is used by thermal convection. The accumulated heat is taken away. Please refer to FIG. 2, which is a perspective view showing an LED light source module having a rotary joint according to another embodiment of the present invention. The LED light source module 100' is similar to the LED light source module 100.
