Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a luminaire, and more particularly to a luminaire that increases the angle of exit. [Prior Art] Although the light-emitting diode (LED) has the advantages of low power consumption and high efficiency, it is limited to the range of its light-emitting angle, and it is used as a light source (for example, when the light source is used as a light source, the light-emitting angle of the light-emitting device is relatively easy. Therefore, the invention is directed to providing a luminaire capable of improving the light-emitting angle. The lamp of the present invention comprises a lamp socket module and a plurality of first light-emitting modules, and the lamp socket module The lamp holder includes a lamp holder and a light-transmitting lamp cover, and the lamp holder has a top surface and a plurality of convex portions protruding toward the top surface, wherein the material protrusions each have a sloped surface, and the light-transmitting lamp cover is coupled to the lamp holder And covering the top surface and the inclined surfaces of the first light-emitting modules disposed on the inclined surfaces of the convex portions. The invention has the effect of designing the inclined surface of the convex portions of the socket and setting the first light-emitting elements On the other hand, the light-emitting angle of the entire luminaire can be increased, and the convex portion also contributes to heat dissipation of the first illuminating element.

Before the present invention is described in detail, it is noted that in the following description of 201209322, the similar elements are identical. Referring to FIG. 1 to FIG. 3, a first preferred embodiment of the lamp 1A of the present invention comprises a lamp socket module l〇〇a, a plurality of first lighting modules 2, and a second lighting module lamp. The PCT module 100a includes a lamp holder
括一座體11、複數凸部13。座體U具有一頂面m、一外 周面112 ’且一中心軸103直立通過座體11頂面m，外周 面112由頂面U1周圍往下延伸並且形成有複數散熱鰭片 15。凸部13相對於頂面111往上凸出，本實施例中，凸部 3的數目為二個（其數量亦可以是二個、四個或五個且均 等分配而環繞於中心軸1〇3)，每兩凸部13之間夾一約工汕 度的彳二向角度B (當凸部13數量為二個、四個或五個時， 其徑向角度可分別為180度、9〇度或72度），每一凸部Η 具有-斜® 以及—相反於斜面13〇的背面⑶斜面 130係面向通過頂面lu的中心軸1〇3並且呈往上漸往遠離 中心軸103的方向傾斜（例如斜面13〇往朝向中心轴1〇3的 方向與頂®⑴时角為12()度，斜面m往遠離中心轴 的方向與燈座i頂面⑴的延伸線之間的夫角八為6〇 度），即如圖3所示，斜面130的延伸線C會在頂面⑴以 下與中心# 103交又且其夾角為3〇度。斜自⑽通常可為 平板狀而背面131可為弧形設計。 在本實施例中，凸部1 31 a 質可為金屬，其可由座體 向上延伸形成並位於頂面lu r J同瓊上而％繞令心軸103 (如圖1所示）。在其他實施例 r凸部丨3亦可為與燈座1 201209322 的政熱鰭片15 一體成型的往上延伸形成並位於頂面111的 周邊上而環繞中心轴103 (如圖4所示）。 在本實施例中，每一凸部13的斜面130可設置一第— 發光模組2，每一第一發光模組2包括一設置在凸部丨3的 斜面130的第一電路板21以及一設置在第一電路板21的 第一發光元件22。在其他實施例中，第一發光模組2亦可 由一個以上的第一發光元件所構成。第二發光模組3包括 一设置在燈座1的頂面1U的第二電路板31以及複數設置 在第二電路板31的第二發光元件32，在本實施例中，第— 發光元件22與第二發光元件32均為發光二極體（LED )。 在本實施例中，當第二發光元件32的設置數量為三個 時，該等第二發光元件32彼此夾約120度角的排列設置在 第二電路板31上，且每一第二發光元件32設置的位置是 位在相鄰兩凸部13之間的徑向角度b内，即每一個凸部j 3 位於兩相鄰的第二發光元件32之間。換言之，位於凸部13 斜面130的第一發光元件22與位於燈座1頂面ill的第二 發光元件32是呈交錯排列放置’因而使得兩相鄰的第二發 光元件32的光軸與位在該兩相鄰的第二發光元件32之間 的該一第一發光元件22的光軸相錯開而不相交，且在本實 施例中，凸部13與第二發光元件32均呈圍繞中心軸103 的方式排列設置’且凸部13圍繞於第二發光元件32外圍 而較第二發光元件32遠離中心軸1〇3。因此，藉由此種設 計’便能增加側向出光量，加大燈具的出光角度。 其中’位在燈座1頂面111的第二發光元件32與位在 201209322 凸部13斜面130上的第一發光元件22的總光通量的比例 為1.1，即凸部13上的所有第一發光元件22發出的總流明 數可等於燈座i頂面⑴上的第二發光元件32發出的總流 明數，可產生最佳的配光曲線。 透光燈罩4結合在燈座丨並且覆蓋座體u的頂面ιη 與斜面130,在本實施例中，透光燈罩4概呈底部截除的圓 球狀，換言之，透光燈罩4是呈下方開口的不完整球狀， 透光燈罩4具有-底緣41，且底緣41往上凹陷形成有複數 缺口 42,缺口 42的數量與燈座u的凸部13數量對應且 缺口 42凹陷的輪廓也與凸部13的外形輪廓相互補，且透 光燈罩4可内含有擴散粒子以使光線發散擴散，以改善熱 點（Hotspot)的現象，且又不會大幅降低效率。 當透光燈罩4結合在燈座1時，該等凸部13恰可分別 嵌合於該等缺口 42的位置，因而使得座體u的頂面lu與 凸部13的斜面130均被覆蓋在透光燈罩4内，而凸部13 的背面131則外露。 此外，較佳者，當透光燈罩4結合在燈座丨時，透光 燈罩4的最大直徑的高度位置可以是落在座體u的頂面 111至透光燈罩4最高點的1/2至1/3的範圍内，且當透光 燈罩4結合在燈座丨時，透光燈罩4的最大直徑的高度位 置恰可落在該等第一發光元件22出光角度正負30度的範 圍内’以使燈具1〇〇的出光角度連到最大。 經實際測試，透過在凸部13的斜面130設置第一發光 模組2，相較於以往只有在燈座頂面設置發光模組，其視角 201209322 約可由120度增加至155度，而發光元件的溫度則可由78 度下降至72.8度’因此，不論是增加出光角度或對led的 散熱，確實具有其具體功效。為增加光線反射，提升燈具 100效率，燈座1頂面lu也可以再增設反射板（圖未示） 〇 如上所述’除了設置在座體U頂面U1的第二發光元 件32是往上照射，本發明更在凸部13的斜面13〇上設置 第一發光模組2，藉由該等側向往斜上方照射的第一發光元 件22，增加整個燈具1〇〇的出光角度’且由於該等第一發 光元件22與第二發光元件32的設置位置都是相錯開的， 可避免光線互相干涉的問題，再者，藉由使凸部13的背面 131外露於透光燈罩4，也可有利於設置在斜面13〇上的第 一發光模組2之散熱。 參閱圖4、圖5，為本發明燈具101的第二較佳實施例 ，大部分元件與第一較佳實施例相似，因此不在贅述。其 與第一較佳實施例不同的地方在於，凸部丨3 ’是從燈座丨，的 散熱鰭片15向上直接延伸形成，每一凸部13，位於斜面13〇 與背面131之間更凹陷形成有一嵌槽132，而透光燈罩4，的 底緣41’則沒有形成如第一較佳實施例所述的缺口 42 (見圖 1)，透光燈罩4’是藉由其底緣41’多處分別嵌入該等凸部 13的嵌槽132内而結合在燈座丨’，因而使凸部13，的斜面 130以及座體11的頂面lu位於透光燈罩4’的覆蓋範圍内 ，凸部13’背面131則同樣外露於透光燈罩4,而有助於散熱 201209322 此外，在本實施例中，每一第一發光模組2，包括兩個 上下排列在凸部13,斜面13〇上的第一發光元件22，而在燈 座1頂面111則未設置任何發光模組而只有一第二電路板5 ，使得該等第一發光模組2’是透過第二電路板5電性連接（ 也可以無需設置任何電路板而僅有反射片）。 在此實施態樣中，每一凸部13，斜面13〇上的兩個第一 發光元件22至燈座丨，頂面ln的垂直高度距離可分別為6 毫米與13毫米，光學效率可達8〇%以上，換言之，在产座 1頂面111可不需要設置第二發光模組3。此外，燈座1，頂 面111也可再增設反射板（圖未示）。 經實際測試，每一發光模組2,包括兩個第一發光元件 22，相較於以往只有在燈座頂面設置發光模組的做法，其 視角約可由120度增加至180度，❿LED晶片溫度則可由 度下降至73纟，因此，確實具有其具體功效。在其他實 施例中’ ® 4與圖5所示的燈座1，態樣也可以配合圖！至 圖第一發光模組2與第二發光模組3的設置方式，亦 即’設置在凸部13,斜面13〇的第一發光模組2也可以只包 括-個第-發光元件22,而燈座i，頂面lu同樣設置包括 複數第m件32的第二發光模組3,而其產生的功效 與第一較佳實施例所述類似。 、參閱圖6,為本發明燈具1〇2的第三較佳實施例，其大 部为疋件與第二較佳實施例相似’故不再說明。在第三較 ^實例中，透光燈罩4，，與第二較佳實施例的透光燈罩 、八不同者在於透光燈罩4，’接合於燈座丨”時是將凸部 201209322 13整個包覆於内。換言之，凸部13的背面131也位於透光 燈罩4，，的覆蓋範圍内而並未外露於透光燈罩4，，之外並且 凸部13的背面131是間隔於透光燈罩4”的内壁面4〇，使 得透光燈罩4”内壁面40與凸部π背面131並未接觸而形 成一空隙104，同樣具有增加出光角度的效果。 較佳者，在第三較佳實施例中，透光燈罩4’’結合在燈 座1”的態樣可以是座體11頂面U1凹陷形成有一圍繞凸部 13的凹槽113 ’藉由透光燈罩4”的底緣41嵌入凹槽I〗]内 而結合在燈座1”，或者，透光燈罩4’’也可以是透過其他方 式結合固定在燈座1” ’關於本段所述透光燈罩4，，與燈座厂 的結合方式也可以應用在第一較佳實施例的透光燈罩4與 燈座1之間。 如上述各實施例，透過將第一發光模組2、2,設置於凸 部13、13’的斜面130,可有效擴大散熱面積，分散熱源， 降低溫度，且利用此方式讓光線行進時接觸到較少介面， 而使菲涅爾損失（fresnel loss)較低’使光學效率達到 %以上。 補充說明的是，當凸部13、13,的斜面13〇傾斜角度不 同時，也可獲得不同的出光角度大小，因此，透過變化各 個凸部13、13’的斜面傾斜角度、第一、第二發光模組2、 2’、3的擺放位置以及與透光燈罩4、4,、4”之間的搭配’ 得到各種不同的出光角度，而使得照明應用範圍更為多元 〇 综上所述，本發明燈具1〇1 ' 102、1〇3藉由該等凸部 10 201209322 13、13’的斜面130設計以及將第一發光模組2、2’設置於其 •上’而確實能增加整個燈具1〇1、1〇2、1〇3的出光角度， 故確實能達成本發明之目的，此外，在部分實施例中，样 由使凸部13、13 ’的背面131外露，也有助於凸部13、13， 的散熱。 惟以上所述者’僅為本發明之較佳實施例而已，當不 能以此限定本發明實施之範圍，即大凡依本發明申請專利 範圍及發明說明内容所作之簡單的等效變化與修飾，皆仍 屬本發明專利涵蓋之範圍内。 【圖式簡單說明】 圖1疋本發明燈具的第一較佳實施例的立體分解圖； 圖2是該第一較佳實施例的該燈座的俯視圖； 圖3是該第一較佳實施例的一透光燈罩結合在該燈座 的剖視圖； 圖4是本發明燈具的第二較佳實施例的立體分解圖； % 圖5是該第二較佳實施例的燈座的剖視圖；以及 圖6是本發明燈具的第三較佳實施例該透光燈罩結合 在該燈座的剖視圖。 201209322 【主要元件符號說明】 100 .. ••…燈具 21 ·· .......第一電路板 100a· ••…燈座模組 22·· ........第一發光元件 101、 102燈具 3 ··· .......第二發光模組 103 ·. .....中心軸 31.. .......第二電路板 104 ·· ••…空隙 32·· ........第二發光元件 1、1’ 、1”燈座 4 ... ........透光燈罩 11 ···. ••…座體 4,、 4”···透光燈罩 Ill .· .....頂面 40·· ........内壁面 112.. ••…外周面 41 · .......底緣 113 ·· ••…凹槽 41’ 、41”底緣 13..·· ••…凸部 42" ........缺口 13’ ·· ••…凸部 5… ........第二電路板 130 ·· .....斜面 A..· ........斜面與頂面炎角 131 ·· ••…背面 B ·· ........徑向角度 15·.·. ••…散熱鰭片 C ·· .......斜面延伸線 2、2, —第一發光模組The body 11 and the plurality of convex portions 13 are included. The seat body U has a top surface m and an outer peripheral surface 112' and a central shaft 103 stands up through the top surface m of the base body 11. The outer peripheral surface 112 extends downward from the periphery of the top surface U1 and is formed with a plurality of heat radiating fins 15. The convex portion 13 is convex upward with respect to the top surface 111. In this embodiment, the number of the convex portions 3 is two (the number may also be two, four or five and equally distributed around the central axis 1〇) 3), every two convex portions 13 sandwich an approximate two-direction angle B (when the number of convex portions 13 is two, four or five, the radial angles may be 180 degrees, 9 respectively 〇 degree or 72 degrees), each convex portion Η has - oblique 以及 and - opposite to the inclined surface 13 〇 the back surface (3) inclined surface 130 faces the central axis 1 〇 3 passing through the top surface lu and is upwardly away from the central axis 103 The direction of the slope is inclined (for example, the slope 13 is oriented toward the central axis 1〇3 and the top® (1) angle is 12 () degrees, and the slope m is between the direction away from the central axis and the extension line of the top surface (1) of the socket i The angle of eight is 6 degrees, that is, as shown in FIG. 3, the extension line C of the slope 130 will intersect the center #103 below the top surface (1) and its angle is 3 degrees. The oblique (10) can generally be flat and the back 131 can be curved. In this embodiment, the convex portion 1 31 a may be a metal, which may be formed by the upward extension of the seat body and located on the top surface lu r J and the main shaft 103 (as shown in FIG. 1 ). In other embodiments, the convex portion 3 may also be formed upwardly integrally formed with the political fin 15 of the lamp holder 1 201209322 and located on the periphery of the top surface 111 to surround the central axis 103 (as shown in FIG. 4). . In this embodiment, a first light-emitting module 2 is disposed on each of the inclined surfaces 130 of the convex portion 13 , and each of the first light-emitting modules 2 includes a first circuit board 21 disposed on the inclined surface 130 of the convex portion 3 and A first light emitting element 22 disposed on the first circuit board 21. In other embodiments, the first light emitting module 2 may also be composed of one or more first light emitting elements. The second light emitting module 3 includes a second circuit board 31 disposed on the top surface 1U of the socket 1 and a second light emitting element 32 disposed on the second circuit board 31. In the embodiment, the first light emitting element 22 Both the second light emitting element 32 and the second light emitting element 32 are light emitting diodes (LEDs). In this embodiment, when the number of the second light-emitting elements 32 is three, the second light-emitting elements 32 are disposed on the second circuit board 31 at an angle of about 120 degrees to each other, and each second light-emitting The position of the element 32 is set within a radial angle b between adjacent two projections 13, i.e., each projection j3 is located between two adjacent second illuminating elements 32. In other words, the first light-emitting element 22 located at the slope 130 of the convex portion 13 and the second light-emitting element 32 located at the top surface ill of the socket 1 are placed in a staggered arrangement, thus making the optical axis and position of the two adjacent second light-emitting elements 32 The optical axes of the first light-emitting elements 22 between the two adjacent second light-emitting elements 32 are staggered without intersecting, and in the present embodiment, the convex portions 13 and the second light-emitting elements 32 are both centered. The shaft 103 is arranged in a manner of 'and the convex portion 13 surrounds the periphery of the second light-emitting element 32 and is away from the central axis 1〇3 from the second light-emitting element 32. Therefore, by this design, the amount of lateral light emission can be increased, and the light exit angle of the lamp can be increased. Wherein the ratio of the total luminous flux of the second light-emitting element 32 located on the top surface 111 of the socket 1 to the first light-emitting element 22 located on the slope 130 of the protrusion 09 is 2012, that is, all the first illuminations on the convex portion 13 The total lumens emitted by element 22 can be equal to the total lumens emitted by second illuminating element 32 on the top surface (1) of the socket i, resulting in an optimum light distribution curve. The light-transmitting lamp cover 4 is coupled to the lamp holder 丨 and covers the top surface η of the body u and the slope 130. In the embodiment, the light-transmitting lamp cover 4 has a spherical shape with a bottom cut-off, in other words, the light-transmitting lamp cover 4 is In the incomplete spherical shape of the lower opening, the transparent lamp cover 4 has a bottom edge 41, and the bottom edge 41 is recessed upward to form a plurality of notches 42. The number of the notches 42 corresponds to the number of the convex portions 13 of the socket u and the notch 42 is recessed. The contour is also complementary to the contour of the convex portion 13, and the light-transmitting lamp cover 4 may contain diffusing particles therein to diffuse and diffuse the light to improve the hotspot phenomenon without greatly reducing the efficiency. When the transparent cover 4 is coupled to the socket 1, the convex portions 13 are respectively fitted to the positions of the notches 42, so that the top surface lu of the base u and the inclined surface 130 of the convex portion 13 are covered. The inside of the light-transmitting cover 4 is exposed, and the back surface 131 of the convex portion 13 is exposed. In addition, preferably, when the light-transmitting lamp cover 4 is coupled to the lamp holder ,, the height position of the maximum diameter of the light-transmitting lamp cover 4 may be 1/2 to the highest point of the top surface 111 of the seat body u to the light-transmitting lamp cover 4 In the range of 1/3, and when the light-transmitting lamp cover 4 is coupled to the lamp holder, the height position of the maximum diameter of the light-transmitting lamp cover 4 may fall within the range of plus or minus 30 degrees of the light-emitting angle of the first light-emitting elements 22' In order to connect the light exit angle of the lamp 1 最大 to the maximum. After the actual test, the first light-emitting module 2 is disposed on the inclined surface 130 of the convex portion 13. Compared with the prior art, only the light-emitting module is disposed on the top surface of the lamp holder, and the viewing angle 201209322 can be increased from 120 degrees to 155 degrees, and the light-emitting element is The temperature can be reduced from 78 degrees to 72.8 degrees. Therefore, whether it is to increase the light angle or heat dissipation to the LED, it has its specific effect. In order to increase the light reflection and improve the efficiency of the lamp 100, the top surface of the lamp holder 1 may also be provided with a reflector (not shown). As described above, the second light-emitting element 32 disposed on the top surface U1 of the base U is illuminated upward. In the present invention, the first light-emitting module 2 is further disposed on the inclined surface 13 of the convex portion 13 , and the light-emitting angles of the entire light-emitting device 1′ are increased by the first light-emitting elements 22 that are irradiated obliquely upward. The arrangement positions of the first light-emitting element 22 and the second light-emitting element 32 are all staggered to avoid the problem of light interference with each other. Further, by exposing the back surface 131 of the convex portion 13 to the light-transmitting cover 4, It is advantageous to dissipate heat from the first light-emitting module 2 disposed on the inclined surface 13〇. Referring to FIG. 4 and FIG. 5, a second preferred embodiment of the lamp 101 of the present invention is provided, and most of the components are similar to the first preferred embodiment, and thus are not described herein. The difference from the first preferred embodiment is that the convex portion ' 3 ′ is formed directly from the heat dissipation fin 15 of the lamp holder ,, and each convex portion 13 is located between the inclined surface 13 〇 and the back surface 131 . The recess is formed with a recess 132, and the bottom edge 41' of the transparent cover 4 does not form the notch 42 (see FIG. 1) as described in the first preferred embodiment, and the transparent cover 4' is formed by the bottom edge thereof. A plurality of 41' are respectively embedded in the recesses 132 of the convex portions 13 to be coupled to the socket 丨', so that the inclined surface 130 of the convex portion 13, and the top surface lu of the base 11 are located in the coverage of the transparent lampshade 4'. The back surface 131 of the convex portion 13 ′ is also exposed to the light-transmitting cover 4 to facilitate the heat dissipation 201209322. In addition, in the embodiment, each of the first light-emitting modules 2 includes two upper and lower protrusions 13 . The first light-emitting element 22 on the inclined surface 13 is not provided with any light-emitting module and only a second circuit board 5 on the top surface 111 of the socket 1, so that the first light-emitting module 2' is transmitted through the second circuit The board 5 is electrically connected (it is also possible to provide no circuit board and only a reflective sheet). In this embodiment, each of the convex portions 13, the two first light-emitting elements 22 on the inclined surface 13〇, the vertical height distance of the top surface ln can be 6 mm and 13 mm, respectively, and the optical efficiency can reach 8〇% or more, in other words, the second light-emitting module 3 is not required to be disposed on the top surface 111 of the housing 1. In addition, the lamp holder 1 and the top surface 111 may be further provided with a reflecting plate (not shown). Through actual testing, each of the light-emitting modules 2 includes two first light-emitting elements 22, and the viewing angle can be increased from 120 degrees to 180 degrees, compared to the conventional method of providing a light-emitting module on the top surface of the lamp holder. The temperature can be reduced to 73 纟, so it does have its specific effect. In other embodiments, the ® 4 and the lamp holder 1 shown in Figure 5 can also be used in conjunction with the figure! The first light-emitting module 2 and the second light-emitting module 3 are disposed, that is, the first light-emitting module 2 disposed on the convex portion 13 and the inclined surface 13 can also include only the first light-emitting elements 22, The lamp holder i, the top surface lu, is also provided with a second lighting module 3 comprising a plurality of mth members 32, and the effect thereof is similar to that described in the first preferred embodiment. Referring to Fig. 6, a third preferred embodiment of the lamp 1 2 of the present invention, which is substantially the same as the second preferred embodiment, will not be described. In the third example, the light-transmitting lamp cover 4 is different from the light-transmitting lamp cover of the second preferred embodiment in that the light-transmitting lamp cover 4, when joined to the lamp holder, is a convex portion 201209322 13 In other words, the back surface 131 of the convex portion 13 is also located in the coverage of the light-transmitting lamp cover 4 without being exposed to the light-transmitting lamp cover 4, and the back surface 131 of the convex portion 13 is spaced apart from the light-transmitting cover. The inner wall surface 4 of the lampshade 4" is such that the inner wall surface 40 of the light-transmitting lamp cover 4" does not contact the convex portion π the back surface 131 to form a gap 104, which also has the effect of increasing the light-emitting angle. Preferably, in the third preferred embodiment. In the embodiment, the light-transmitting lamp cover 4 ′′ is coupled to the lamp holder 1 ′. The top surface U1 of the seat body 11 is recessed to form a groove 113 ′ surrounding the convex portion 13 ′ by the bottom edge 41 of the light-transmitting lamp cover 4 ′′. The light-filled lamp cover 1 ′′ is incorporated into the lamp holder 1 ′′, or the light-transmitting lamp cover 4 ′′ may be fixed to the lamp holder 1′′ by other means. The combination of the manufacturer can also be applied between the light-transmitting lamp cover 4 of the first preferred embodiment and the lamp holder 1. In the above embodiments, by disposing the first light-emitting modules 2 and 2 on the inclined surface 130 of the convex portions 13 and 13', the heat dissipation area can be effectively enlarged, the heat source can be dispersed, the temperature can be lowered, and the light can be contacted when traveling. The interface is less, and the Fresnel loss is lower, so that the optical efficiency is more than %. It is added that when the inclined faces 13 of the convex portions 13, 13 are different in inclination angle, different The size of the light exiting angle, therefore, by changing the inclined angle of the inclined faces of the respective convex portions 13, 13', the positions of the first and second light emitting modules 2, 2', 3, and the light-transmitting lampshades 4, 4, 4" The collocation between the two gives a variety of different light-emitting angles, and the illumination application range is more diverse. In summary, the lamp of the present invention 1〇1 '102, 1〇3 by the convex portions 10 201209322 13, 13' The design of the inclined surface 130 and the arrangement of the first light-emitting modules 2, 2' on the top thereof can indeed increase the light-emitting angle of the entire lamps 1〇1, 1〇2, and 1〇3, so that the object of the present invention can be achieved. In addition, in some embodiments, the convex portions 13, 13 are made by The rear surface 131 of the 'exposed light also contributes to the heat dissipation of the convex portions 13, 13.
