下面將結合圖式對本發明實施例作進一步之詳細說明。 [0008] 請參閱圖4，為本發明第一實施例所提供的一種於隧道20 内安裝燈具21的狀態示意圖。該隧道21的截面呈弓形， 其包括一圍設於路面22上方且與該路面22相對的一弧形 的内壁面23。該路面22包括分別位於左右兩側的第一車 道221和第二車道222，所述第一車道221和第二車道222 分別供車輛單向行駛。該内壁面23的左右兩側上方沿隧 道21延伸的X方向分別等間隔地安裝有複數燈具21，左右 兩侧的燈具21分別主要用於對隧道20内靠近對應侧的第 一、第二車道221、222進行照明。優選地，該内壁面23 為一粗糙表面，因此部分出射在該内壁面23上的光線產 生擴散反射或者漫反射的現象，使得光線較為均勻，呈 現出較為舒適的光照明環境。其中，該粗糙的内壁面23 可以通過喷沙處理方式形成。 [0009] 該燈具21包括一平板狀的電路板（圖未示）及安裝於電 路板上的多個固態光源25。請參閱圖5，每一光源25包括 一發光二極體250及與該發光二極體250配合的光學元件 。所述光學元件包括一透鏡251及一反射鏡252。該透鏡 251包括一底面253、一與底面253相對的“V”字形頂面 254及連接所述底面253和頂面254的側面255。該底面 253的中央向頂面254所在方向凹陷設有一收容發光二極 體250的收容室256。該發光二極體250具有一中心軸線Η ，發光二極體250設置在該透鏡251的底部的幾何中心處 ，透鏡251通過該中心軸線Η呈中心對稱。該侧面255上設 有沿中心軸線Η方向排列的複數鑛齒狀的光學微結構257 099103546 表單編號Α0101 第6頁/共38頁 0992006659-0 201128109 Ο 。每一光學微結構257包括一第一斜面2571及與該第一斜 面2571相交的一第二斜面2572，所述第一斜面2571與第 二斜面2572之間於遠離中心軸線Η的一端相交形成一銳角 。該頂面254是一個二次曲面，該發光二極體250與透鏡 251光學耦合，即發光二極體250發出的光線直接進入透 鏡251内，並經由透鏡251的光學作用射出。其中，發光 二極體250發出的一部分光線射向頂面254，在頂面254 發生全反射並以與中心軸線Η大致呈9 0度角經由側面2 5 5 射出，而另一部分光線直接射向侧面2 5 5經由侧面2 5 5出 射。因此，經由透鏡251出射的光線會偏離中心轴線Η— 定角度，使得該光源25發出的光線在沿垂直於路面延伸 的Υ方向上偏折向該光源25的側向出射而形成翼型的配光 曲線，從而改變該光源25照射路面22的光線中的光強度 較大的光線所集中的範圍。 [0010] 通常，在路面22行駛的車輛駕駛員的眼睛與光源25之間 的相對位置確定的情況下，自眼睛所在垂直面偏轉45度 ο 至85度之間的範圍為容易產生直接眩光的角度範圍，在 此，將其定義為眩光區域。具體實施時，當光源25位於 路面22上方並相對路面22上行駛的車輛駕駛員的眼睛位 置確定的情況下，由於光源25中經由透鏡251出射的光線 可向遠離中心軸線Η的側向偏折一定角度，因此，通過調 整該透鏡251使得光線偏折的角度的大小可使得光源25發 出的大部分光線偏折後位於該眩光區域之外，從而使得 眩光區域内的光線的光強度減弱，以減少甚至防止眩光 的產生。其中，所述大部分光線也是光源25所發出的光 099103546 表單編號Α0101 第7頁/共38頁 0992006659-0 201128109 線中光強度較大的光線，假設某光線直射眼睛時候可以 產生直接眩光的光線的光強度為一定值，那麼，光強度 大於該一定值的光線均屬於光強度較大的光線。進一步 的，由於所述燈具25是安裝於随道2〇的内壁面23的兩側 進行照明，且該隧道20的内壁面23呈弓形而圍設於路面 22的上方，因此，在垂直於路面22延伸的Y方向上經由透 鏡251出射的光線相對該中心軸線Η偏折的角度應使得光 源25出射的一部分光線可以直接射在光源25的周圍的内 壁面23上，通過光線在内壁面23上發生漫反射或者擴散 反射後出射至路面22 ’因而形成均勻地光照環境。優選 地，在垂直於路面22延伸的Υ方向上光源25發出的大部分 光線相對中心轴線Η偏折後分別集中在眩光區域的兩侧， 且在中心轴線Η上的光線的光強度小於其最大光強度的三 分之一，如此可避免強光直接射向路面22上車輛駕駛員 而產生直接眩光。由於側面255形成有鋸齒狀光學微結構 257，當光源25的光線由光學微結構257的第一斜面2571 或第二斜面2572出射時:，在第一斜面2571或第二斜面 2572上產生折射，寸進一步使得從侧面255出射的光線集 中在預定的非眩光區域範圍内，同時更多的光線可以通 過射向内壁面2 3發生漫反射或者擴散反射後形成均勻的 光照環境。 [0011] 該反射鏡252位於該透鏡251的一側，其包括一面向發光 二極體250並用於反射光線的弧形的反射面2521。該反射 鏡252於發光二極體250所在平面的投影與該透鏡251的 頂面254於發光二極體250所在平面的投影部分重疊，優 099103546 表單編號Α0101 第8頁/共38頁 0992006659-0 201128109 ❸ Ο 選的是，該反射鏡252於發光二極體250所在平面的投影 與發光二極體250的出光面部分重疊。該反射鏡252用於 使發光二極體250發出的光線在路面22延伸的叉方向上偏 折向該燈具21的側向出射，從而使得燈具2丨照射路面22 的光線沿路面22延伸的X方向的配光曲線為一不對稱的配 光曲線。請再次參閱圖4，使用時，所述燈具21設置在路 面22上方’該燈具21的軸線211沿路面22延伸的X方向將 該路面22的車道221、222劃分為行車靠近侧265及行車 遠離側266，在路面22上行駛的車輛由行車靠近側265駛 向行車遠離侧266 »通過反射鏡252的反射作用使得光源 25照射路面2|的光線在路面22延伸的X方向的配光曲線中 光強度最大值向行車遠離侧266方向偏移中心軸線Η—定 角度，如45度角，如此可使得光源25照射路面的光線中 於行車靠近侧265的光線的光強度遠小於行車遠離侧266 的光線的光強度。由於車輛在沿路面22延伸的X方向行進 的過程中，容易產生直接眩洗的方'向通常會發生在車輛 駕駛員的前方，也就是發生在車ι輸駕駛員位於行車靠近 側265時’自¥眼晴所在垂直面偏轉45度至85度之間的範 圍内，因此，通過反射鏡252使得光源25照射路面22的光 線向行車遠離侧266偏折，使得行車靠近侧265的光強度 減弱，當駕駛員位於行車靠近側265時，其眼睛受到的光 線刺激沒有超出正常範圍，不會受到直接咳光的影響， 而當車輛由行車靠近側265駛向行車遠離側266時，駕駛 員背向光線照射方向，其也不會受到直接眩光的影響。 優選的，該反射鏡252使得光源25照射路面22的光線在沿 099103546 路面22延伸的方向上向行車遠離侧266偏折後，於行車靠 表單編號Α0101 第9頁/共38頁 0992006659-0 201128109 近側265的45度角處的光線的光強度小於行車遠離側266 的光線的最大光強度的六分之一。優選的，於行車靠近 侧265的45至85度角處的光線的光強度小於行車遠離側 266的光線的最大光強度的六分之一。 [0012]請參閱圖6，為光源25在垂直於路面延伸的γ方向上的配 光曲線圖，C點示出透鏡251使得發光二極體250發出的光 線在中心軸線Η方向上的光強度約為280坎德拉（cd)，D 點示出發光二極體25 0發出的光線的最大光強度約為890 坎德拉（cd) ’該發光二極體250發出的光線在中心轴線Η 上的光強度小於其最大光強度的三分之一。因此，當光 源25分別位於隧道20的内壁面23的兩側的一定高度處， 可使得出射至路面22的光強度較大的光線主要位於眩光 區域的兩側，而不會直接對行駛在車道221、222上的車 輛的駕駛員產生直接眩光的影響。請參閱圖7，為光源25 在路面22的延伸X方向上的配光曲線圖，Ε點示出反射鏡 252使得發光二極體250發出的光線在路面的延伸X方向上 的最大光強度相對中心轴線Η向行車遠離側266偏移大致 5〇度角，Ε點示出發光二極體250發出的光線在行車遠離 側266的最大光強度大致為750坎德拉（cd)，而F點示出 行車靠近侧265的45度角處的光強度大致為1〇〇坎德拉 (cd)。因此，當駕駛員位於行車靠近側265時，其眼睛受 到的光線刺激沒有超出正常範圍’不會受到直接眩光的 影響，而當車輛由行車靠近側265駛向行車遠離侧266時 ’駕駛員背向光線照射方向，其也不會受到直接眩光的 影響。

面353。該光源35具有一以發光二極體25〇所在位置為中 心的對稱轴I。該透鏡351位於發光二極體25()的上方，其 入光面350面向發光二極體250設置，而出光面352上設 有複數環形的條狀鑛齒形凸起352。每一凸起352包括一 第一鋸齒面3521及一連接該第一鋸齒面3521的第二鋸齒 面3522，其中’所述第一鋸齒面3521位於對應凸起352 遠離對稱轴I的一侧，且垂直於入光面35〇。而對於位於 對稱轴I同一側的每一凸起352而言，其第二鋸齒面3522 分別連接相鄰兩側凸起352的第一鋸齒面3521。如圖8中 箭頭所示，發光二極體250發出的光線經入光面350入射 至透鏡351，當光線由第一鋸齒面3521或第二鋸齒面 3522上出射時均偏離對稱軸丨一定角度，使得該光源35發 出的光線偏折向該光源3 5的側南出身而形成翼型的配光 曲線。因此光源35於垂直於路面22延伸的Υ方向上出射的 大部分光線遠離對稱軸I，所述光強度較大的光線位於眩 光區域的外側’而在眩光區域内的光線的光強度相對減 弱，可以避免強光射向車輛或者駕駛員而產生直接眩光 。通過調整該第二鋸齒面3522相對第一鋸齒面3521傾斜 的角度，便可獲得與第一實施例中的光源25相似的配光 曲線。 [0014] 圖9所示為本發明第三實施例所提供的一種燈具21的光源

一收容發光二極體250的收容空間456。該出光面454的 中央形成為一漏斗狀的凹面458。如圖9中箭頭所示，發 光二極體250發出的光線經入光面453入射至透鏡451， 當光線由出光面454出射時在出光面454中央的凹面458 處發生全反射，改變原來的照射方向而.經由側面4 5 5出射 。通過調整該凹面458的曲率和面積，便可獲得與第一實 施例的光源2 5的相似的配光曲線。 [0015] 圖10所示為本發明第四實施例所提供的一種燈具21的光 源55，其與上述第一實施例的區別在於：該光源55中的 反射鏡552的結構不同。該反射鏡552包括一面向發光二 極體250以用於反射光線的直線形的反射面5521。 [0016] 圖11和圖12所示為本發明第五實施例所提供的一種燈具 21的光源，該光源包括複數第一光源651和複數第二光源 652。其中，第一光源651包括一發光二極體250及一第 一透鏡6510，該第一透鏡6510結構與上述第一實施例中 的光源25中透鏡251的結構完全相同。第二光源652包括 一發光二極體250及一第二透鏡6521。該第二透鏡6521 包括一與發光二極體250相鄰的入光面6521、一與入光面 6521相對的出光面6522以及一連接於所述入光面6521與 出光面6522之間的豎直的侧壁6523。該入光面6521呈矩 099103546 表單編號A0101 第12頁/共38頁 0992006659-0 201128109 形，該第二透鏡652具有一穿過入光面6520幾何中心的中 心軸N。該出光面6522為一與該入光面6520成一預定失 角的内凹曲面。其中，該出光面6522朝向入光面6520所 在方向凹陷，且出光面6522相對入光面6520的斜率由一 側向另一側逐漸增加。使用時，安裝燈具21時使得第二 透鏡652的出光面652 2相對入光面6520的斜率較小的一 侧置於行車靠近侧265，而另一侧置於行車遠離側266。 如圖12中箭頭所示，發光二極體250發出的光線經入光面 6520入射至第二透鏡652内部，進而由第二透鏡652的出 光面6522出射。當光線由出光面6522出射時，在該出光 面6522發生折射，使得光線向行車遠離側266偏折。因此 ，位於行車遠離側266的光強度較大，而位於行車靠近側 265的光強度相對較弱，通過調整第二透鏡652的出光面 6522的曲率，便可使得光源照射路面22的光線於路面22 延伸的X方向上向行車遠離側266偏折一預定的角度。第 一光源651中透鏡6210的作用與光源25中透鏡251的作用 相同，而如圖11中箭頭所示，發光二極體250發出的光線 經由第一透鏡6510出射後，均偏離中心軸線Η—預定範圍 ，如此可使得在垂直路面22延伸的Υ方向上光強度較大的 光線位於眩光區域的兩侧，而在眩光區域内的光線的光 強度相對減弱，從而避免強光射向車輛或者駕駛員而產 生直接眩光。 [0017] 圖13所示為本發明第六實施例所提供的一種燈具21的光 源，其與上述第五實施例的區別在於：第二光源752中透 鏡7521的結構不同。該透鏡7521包_括一矩形的主體部 099103546 表單編號Α0101 第13頁/共38頁 0992006659-0 201128109 7520及形成於該主體部7520的頂面7523的中央的光學部 7522。該光學部7522的外表面7524為一朝遠離主體部 7520的方向凸起的球面，該光學部7522的厚度從第二光 源7 5 2的一側向另一側逐漸增加，即光學部7 5 2 2的外表面 7524與主體部7520的頂面7523之間的距離從一側向另_ 側逐漸增加。主體部7520的底面於靠近光學部7522的厚 度較小的一側的地方向頂面所在方向凹陷形成一收容發 光二極體250的空間7525。如圖13中箭頭所示，以發光 二極體25 0所在位置為中心异有一轴線Μ ’發光二極體25〇 發出的光線入射至透政7 5 爾，當先線由光學部7 5 2 2的 外表面7524出射時，在該外表面7524發生折射，使得光 線向光學部7522的厚度較大的一側偏1折。使，用時，將透 鏡7521的光學部7522厚度較大的一侧置於行車遠離側 266 ’經由該透鏡7521出射的光線向行車遠離侧266偏折 ，因此，位於行車遠離侧266的光強度較大，而位於行車 靠近侧265的光強度較弱，通過調整該光學部7522的外表 面7524的曲率，便可使得光源照射路面22的光線於路面 22延伸的X方向上向行車遠離側2 6 6偏折一預定的角度。 [0018]圖14所示為本發明第七實施例所提供的一種燈具21的光 源’其與上述第五實施例的區別在於：第二光源852中透 鏡8521的結構不同。該透鏡8521具有一個板狀輪廓，其 包括一入光面8520及一與入光面852〇相對的出光面8522 。該透鏡8521位於發光二極體25〇的上方，其入光面 8520為平面且與發光二極體25〇相鄰設置，而出光面 8522上没有複數條狀的鋸齒形突起8523。每一突起8523 099103546 表單編號A0101 第14頁/共38頁 0992006659-0 201128109 Ο 包括一豎直面8525及一連接該豎直面8525的傾斜面8524 。其中，所述豎直面8525相互平行，分別垂直於入光面 8520，而傾斜面8524傾斜延伸並連接其相鄰兩侧的豎直 面8525。如圖14中箭頭所示，發光二極體250發出的光 線經入光面8520入射至透鏡8521，當光線經由出光面 8522上的豎直面8525或傾斜面8522出射時發生折射，並 朝向對應突起8523的豎直面8525所在一側偏折射出。使 用時，安裝燈具21使得透鏡8521中突起8523的豎直面 8525置於行車遠離侧266的一側’因此，經由該透鏡 8521出射的光線向行車遠離側266偏折。通過調整該突起 8523中傾斜面8524的斜率，.:便可使得光源颯射路面22的 光線於路面22延伸的X方向上向行車遠離側266偏折一預 .u ο. 定的角度。 u [0019] 終上所述’第一、第二、第三實施例中的光源25、35、 Ο 45中的透鏡251、351、451分別，可用於改變發光二極體 250發出的光線中的光強度較大的光線所集中的範圍’使

[Prior Art] When a vehicle enters or exits a tunnel, a sudden change in brightness may cause a black hole effect or a "white hole effect" in the driver's vision, thereby causing a hidden danger to the driver. To solve this safety problem, the road tunnel is solved. It is necessary to configure the lighting fixture. As shown in Fig. 1, the section of the tunnel 100 is generally arched, and the lamp 101 is disposed at the center of the inner wall surface of the tunnel 10, and the light emitted by the lamp 丨〇1 is centered on the road surface 10 2 In the prior art, although the radiation range of the lamp 101 in the X direction of the vehicle lane is larger than the radiation range of the gamma direction perpendicular to the X direction, the light utilization efficiency of the lamp 101 can be effectively improved. The range of light radiation formed by 〇1 in the X direction is still symmetrically distributed around the luminaire 1〇1 itself, that is, the illuminator 101 is illuminating on both sides in the X direction, and the angles 0 1 and 0 2 are equal, usually 6>1=02 = 7〇. Here, the radiation angle can also be called the half-peak side angle, which means that half of the maximum light intensity is measured from the vertical road surface to the left and right sides. Angle It is the angle between the light emitted by the light source and the vertical line of the maximum luminous intensity of 5〇%. See Figure 2 for the light distribution of the lamp 1 〇1 in Figure 1 in the X direction parallel to the vehicle. Curve, the light intensity of the light corresponding to point A in the figure is 〇% of the maximum light intensity of the lamp 101 in the range of 0 to 90 degrees, and the light intensity of the point B corresponding to the light is the maximum of the brightness of the lamp 101 to 90 degrees. Light intensity, the radiation angle of the lamp 101 is approximately equal to 70 degrees. Please refer to Figure 3, when the light 099103546 Form No. A0101 Page 4 / Total 38 Page 0992006659-0 201128109 The source 101 is located above the human eye 104, from the human eye 1〇 4 In the range where the vertical plane 1〇5 is deflected between 45 degrees and 85 degrees, the light source 101 easily causes direct glare to the human eye 1〇4. It can be seen that the conventional light guide 101 in the lane 1 will drive. The eye of the person causes direct glare. [0004] A road lighting device capable of effectively reducing glare will be described below by way of example. [0005] A road lighting device comprising at least one for illuminating a road surface Light 0 source, the at least - light source package - light a diode and at least one optical component associated with the _photodiode, the optical component deflecting light emitted by the at least one light source laterally toward the at least one light source to form a wing in a direction extending perpendicular to the road surface The first curve is shaped such that the light having a larger light intensity is respectively located on both outer sides of the glare region, and the light emitted by the at least one light source is deflected to a predetermined angle from the side away from the vehicle in a direction extending parallel to the road surface. Compared with the prior art, when the road surface illumination device is irradiated to the road surface, the light is deflected toward the lateral direction of the at least one light source in a direction perpendicular to the road surface to form a wing-shaped light distribution curve, so that the light The stronger light rays are respectively located on the two outer sides of the glare region, so that the light intensity in the glare region near the axis of the light source is weakened without causing direct glare to the driver of the vehicle, and the light is extended in a direction parallel to the road surface. Driving away from the reverse deflection, when the vehicle is driving on the road, the light intensity near the side of the vehicle will not exceed the range of the human eye, and will not drive the vehicle. Impact of direct glare, so as to effectively protect the traffic safety of the driver. [Embodiment] 0992006659-0 099103546 Table 煸 A0101 Page 5 of 38 201128109 [0007] The embodiments of the present invention will be further described in detail below with reference to the drawings. Please refer to FIG. 4 , which is a schematic diagram of a state in which a light fixture 21 is installed in a tunnel 20 according to a first embodiment of the present invention. The tunnel 21 has an arcuate cross section and includes an arcuate inner wall surface 23 that is disposed above the road surface 22 and opposite the road surface 22. The road surface 22 includes a first lane 221 and a second lane 222 which are respectively located on the left and right sides, and the first lane 221 and the second lane 222 are respectively for one-way driving of the vehicle. A plurality of lamps 21 are mounted at equal intervals in the X direction extending along the tunnel 21 in the upper and lower sides of the inner wall surface 23, and the lamps 21 on the left and right sides are mainly used for the first and second lanes in the tunnel 20 adjacent to the corresponding sides. 221, 222 for illumination. Preferably, the inner wall surface 23 is a rough surface, so that the light which is partially emitted on the inner wall surface 23 causes diffuse reflection or diffuse reflection, so that the light is relatively uniform, and a relatively comfortable light illumination environment is exhibited. Among them, the rough inner wall surface 23 can be formed by sandblasting. The lamp 21 includes a flat circuit board (not shown) and a plurality of solid state light sources 25 mounted on the circuit board. Referring to FIG. 5, each light source 25 includes a light emitting diode 250 and an optical component mated with the light emitting diode 250. The optical component includes a lens 251 and a mirror 252. The lens 251 includes a bottom surface 253, a "V" shaped top surface 254 opposite the bottom surface 253, and a side surface 255 connecting the bottom surface 253 and the top surface 254. The center of the bottom surface 253 is recessed in the direction of the top surface 254 to define a receiving chamber 256 for receiving the LED body 250. The light-emitting diode 250 has a central axis Η, and the light-emitting diode 250 is disposed at a geometric center of the bottom of the lens 251, and the lens 251 is centrally symmetric by the central axis Η. The side surface 255 is provided with a plurality of mineral-shaped optical microstructures arranged in the direction of the central axis 257 099103546 Form No. 1010101 Page 6 of 38 0992006659-0 201128109 Ο . Each of the optical microstructures 257 includes a first inclined surface 2571 and a second inclined surface 2572 intersecting the first inclined surface 2571. The first inclined surface 2571 and the second inclined surface 2572 intersect at an end away from the central axis 形成 to form a Sharp angle. The top surface 254 is a quadric surface. The light emitting diode 250 is optically coupled to the lens 251. That is, the light emitted by the light emitting diode 250 directly enters the lens 251 and is emitted through the optical action of the lens 251. Wherein, a part of the light emitted by the light-emitting diode 250 is incident on the top surface 254, is totally reflected on the top surface 254, and is emitted through the side surface 25 5 at an angle of substantially 90 degrees from the central axis ,, and another portion of the light is directly directed toward Side 2 5 5 exits through side 2 5 5 . Therefore, the light emitted through the lens 251 is offset from the central axis by an angle such that the light emitted by the light source 25 deflects laterally toward the light source 25 in a direction perpendicular to the road surface to form an airfoil. The light distribution curve changes the range in which the light having a large intensity of light in the light that the light source 25 illuminates the road surface 22 is concentrated. [0010] Generally, in the case where the relative position between the eyes of the driver of the vehicle traveling on the road surface 22 and the light source 25 is determined, the range from 45 degrees ο to 85 degrees from the vertical plane of the eye is easy to generate direct glare. The angular range, here defined as the glare area. In a specific implementation, when the light source 25 is located above the road surface 22 and is determined relative to the eye position of the driver of the vehicle traveling on the road surface 22, the light emitted from the light source 25 via the lens 251 may be laterally deflected away from the central axis. At a certain angle, therefore, by adjusting the lens 251, the angle of the light deflected may be such that most of the light emitted by the light source 25 is deflected and located outside the glare area, so that the light intensity of the light in the glare area is weakened, so that Reduce or even prevent the generation of glare. Wherein, most of the light is also the light emitted by the light source 0. 099103546 Form No. 1010101 Page 7 / Total 38 Page 0992006659-0 201128109 Light with a relatively high intensity of light in the line, assuming direct light can be generated when a certain light directly hits the eye. The light intensity is a certain value, then the light whose light intensity is greater than the certain value belongs to the light with higher light intensity. Further, since the lamp 25 is illuminated on both sides of the inner wall surface 23 of the channel 2, and the inner wall surface 23 of the tunnel 20 is arcuate and is disposed above the road surface 22, it is perpendicular to the road surface. The angle of the light emitted through the lens 251 in the extended Y direction is offset with respect to the central axis 应 such that a part of the light emitted from the light source 25 can be directly incident on the inner wall surface 23 around the light source 25, and the light passes through the inner wall surface 23. After diffuse reflection or diffuse reflection, it exits to the road surface 22' and thus forms a uniform illumination environment. Preferably, most of the light emitted by the light source 25 in the Υ direction extending perpendicular to the road surface 22 is deflected relative to the central axis 后 and then concentrated on both sides of the glare region, and the light intensity of the light on the central axis 小于 is less than One-third of its maximum light intensity prevents direct glare from being directed at the driver of the vehicle on the road surface 22 directly. Since the side surface 255 is formed with the zigzag optical microstructure 257, when the light of the light source 25 is emitted by the first slope 2571 or the second slope 2572 of the optical microstructure 257: refraction occurs on the first slope 2571 or the second slope 2572. Further, the light emitted from the side surface 255 is concentrated in a predetermined non-glare area, and more light can be diffusely reflected or diffused and reflected by the inner wall surface 23 to form a uniform illumination environment. [0011] The mirror 252 is located at one side of the lens 251 and includes an arc-shaped reflecting surface 2521 facing the light-emitting diode 250 and for reflecting light. The projection of the mirror 252 on the plane of the LED body 250 overlaps with the projection of the top surface 254 of the lens 251 on the plane of the LED body 250, preferably 099103546 Form No. 1010101 Page 8 / Total 38 Page 0992006659-0 201128109 ❸ 投影 The projection of the mirror 252 on the plane of the LED 220 partially overlaps the light-emitting surface of the LED 230. The mirror 252 is configured to deflect the light emitted by the LED 230 from the lateral direction of the road surface 22 toward the lateral direction of the lamp 21, so that the light of the lamp 2 illuminating the road surface 22 extends along the road surface 22 The light distribution curve of the direction is an asymmetric light distribution curve. Referring again to FIG. 4, in use, the luminaire 21 is disposed above the road surface 22. The axis 211 of the luminaire 21 divides the lanes 221, 222 of the road surface 22 into the approaching side 265 and away from the road in the X direction extending along the road surface 22. Side 266, the vehicle traveling on the road surface 22 is driven by the approaching side 265 toward the driving away side 266. » The reflection of the mirror 252 causes the light source 25 to illuminate the road surface 2| in the X-direction light distribution curve of the road surface 22 The maximum intensity of the light is offset from the central axis by a direction away from the side 266, such as a 45 degree angle, such that the light intensity of the light illuminating the road surface near the side 265 of the light source 25 is much smaller than the distance 266 away from the driving side. The light intensity of the light. As the vehicle travels in the X direction extending along the road surface 22, the side that tends to produce direct glare usually occurs in front of the driver of the vehicle, that is, when the driver of the vehicle is on the approach side 265 of the vehicle. Since the vertical plane of the eye is deflected in a range between 45 degrees and 85 degrees, the light illuminating the road surface 22 by the light source 25 is deflected toward the traveling away side 266 by the mirror 252, so that the light intensity of the approaching side 265 is weakened. When the driver is on the approaching side 265, the eye is not stimulated by the light beyond the normal range and is not affected by direct coughing. When the vehicle is driven from the approaching side 265 toward the driving away side 266, the driver's back It is directed toward the light and it is not affected by direct glare. Preferably, the mirror 252 causes the light of the light source 25 to illuminate the road surface 22 to be deflected toward the driving away side 266 in the direction extending along the road surface 22 of 099103546, after the driving form number Α0101, page 9 / total 38 pages 0992006659-0 201128109 The light intensity at the 45 degree angle of the proximal side 265 is less than one sixth of the maximum light intensity of the light traveling away from the side 266. Preferably, the light intensity at a 45 to 85 degree angle of the approaching side 265 of the vehicle is less than one sixth of the maximum light intensity of the light traveling away from the side 266. [0012] Please refer to FIG. 6 , which is a light distribution curve of the light source 25 in the γ direction extending perpendicular to the road surface, and C point shows the light intensity of the light emitted by the light emitting diode 250 in the direction of the central axis C. Approximately 280 candelas (cd), the D point shows that the maximum light intensity of the light emitted by the light-emitting diode 25 0 is about 890 candelas (cd). The light intensity of the light emitted by the light-emitting diode 250 on the central axis Η Less than one third of its maximum light intensity. Therefore, when the light sources 25 are respectively located at a certain height on both sides of the inner wall surface 23 of the tunnel 20, it is possible to obtain that the light having a greater intensity of light incident on the road surface 22 is mainly located on both sides of the glare region, and does not directly travel in the lane. The driver of the vehicle on 221, 222 has the effect of direct glare. Please refer to FIG. 7 , which is a light distribution diagram of the light source 25 in the extension X direction of the road surface 22 , and the point 示出 shows that the mirror 252 causes the light emitted by the LED body 250 to have a maximum light intensity in the extension X direction of the road surface. The central axis turns away from the side 266 by a distance of approximately 5 degrees, and the point indicates that the maximum light intensity of the light emitted by the light-emitting diode 250 on the away side 266 is approximately 750 candelas (cd), while the point F shows the line. The light intensity at the 45 degree angle of the car near side 265 is approximately 1 〇〇 candela (cd). Therefore, when the driver is on the approaching side 265, the eye is not stimulated by the light beyond the normal range' without being affected by direct glare, and when the vehicle is approaching the side 265 from the driving side toward the driving away side 266, the driver's back It is directed toward the light and it is not affected by direct glare. 099103546 Form bat number A0101 Page 10 / Total 38 page 0992006659-0 201128109 [0013] FIG. 8 shows a light source 35 of a lamp 2丨 according to a second embodiment of the present invention, which is similar to the first embodiment described above. The difference is that the structure of the lens 351 in the light source 35 is different. The lens 351 has a circular plate-like profile including a planar light incident surface 350 and a light exit surface 353 opposite the light incident surface 35A. The light source 35 has an axis of symmetry I centered on the position of the light-emitting diode 25'. The lens 351 is disposed above the light-emitting diode 25(), and the light-incident surface 350 is disposed facing the light-emitting diode 250, and the light-emitting surface 352 is provided with a plurality of annular strip-shaped orthodontic protrusions 352. Each of the protrusions 352 includes a first serration surface 3521 and a second serration surface 3522 connecting the first serration surface 3521, wherein the first serration surface 3521 is located on a side of the corresponding protrusion 352 away from the axis of symmetry I. And perpendicular to the entrance surface 35 〇. For each of the protrusions 352 on the same side of the axis of symmetry I, the second indented surface 3522 connects the first indented surface 3521 of the adjacent side protrusions 352, respectively. As shown by the arrow in FIG. 8, the light emitted from the LED 230 is incident on the lens 351 through the light incident surface 350. When the light is emitted from the first sawtooth surface 3521 or the second sawtooth surface 3522, the light is offset from the axis of symmetry by a certain angle. The light emitted by the light source 35 is deflected toward the south side of the light source 35 to form an airfoil light distribution curve. Therefore, most of the light emitted by the light source 35 in the x-direction extending perpendicular to the road surface 22 is away from the axis of symmetry I, and the light having a higher light intensity is located outside the glare region, and the light intensity of the light in the glare region is relatively weakened. Direct glare can be avoided by glare from the vehicle or the driver. By adjusting the angle at which the second serration surface 3522 is inclined with respect to the first serration surface 3521, a light distribution curve similar to that of the light source 25 in the first embodiment can be obtained. 9 is a light source 099103546 of the luminaire 21 according to a third embodiment of the present invention. Form number Α0101 page/38 page 0992006659-0 201128109 45, which differs from the first embodiment described above in that: The structure of the lens 451 in the light source 45 is different. The lens 451 has a substantially hemispherical contour and includes a light incident surface 453, a light exit surface 454 opposite to the light incident surface 453, and a curved side surface 455 connecting the light incident surface 453 and the light exit surface 454. The center of the light incident surface 453 is recessed toward the light emitting surface 454 to form a receiving space 456 for receiving the light emitting diode 250. The center of the light exit surface 454 is formed as a funnel-shaped concave surface 458. As shown by the arrow in FIG. 9, the light emitted from the LED 230 is incident on the lens 451 through the light incident surface 453. When the light is emitted from the light exit surface 454, total reflection occurs at the concave surface 458 at the center of the light exit surface 454, and the original is changed. The direction of illumination is emitted through the side surface 45 5 . By adjusting the curvature and area of the concave surface 458, a light distribution curve similar to that of the light source 25 of the first embodiment can be obtained. 10 is a light source 55 of a luminaire 21 according to a fourth embodiment of the present invention, which differs from the first embodiment in that the structure of the mirror 552 in the light source 55 is different. The mirror 552 includes a linear reflecting surface 5521 that faces the light emitting diode 250 for reflecting light. 11 and FIG. 12 show a light source of a luminaire 21 according to a fifth embodiment of the present invention. The light source includes a plurality of first light sources 651 and a plurality of second light sources 652. The first light source 651 includes a light emitting diode 250 and a first lens 6510. The first lens 6510 has the same structure as the lens 251 of the light source 25 in the first embodiment. The second light source 652 includes a light emitting diode 250 and a second lens 6521. The second lens 6521 includes a light incident surface 6521 adjacent to the light emitting diode 250, a light emitting surface 6522 opposite to the light incident surface 6521, and a vertical connection between the light incident surface 6521 and the light emitting surface 6522. Straight side wall 6523. The light incident surface 6521 is in the form of a moment 099103546, Form No. A0101, Page 12/38, 0992006659-0 201128109. The second lens 652 has a central axis N passing through the geometric center of the light incident surface 6520. The light exiting surface 6522 is a concave curved surface that is at a predetermined angle of deviation from the light incident surface 6520. The light exiting surface 6522 is recessed toward the light incident surface 6520, and the slope of the light exiting surface 6522 relative to the light incident surface 6520 gradually increases from one side to the other side. In use, the luminaire 21 is mounted such that the side of the light exiting surface 6522 of the second lens 652 with respect to the light incident surface 6520 is placed on the approaching side 265 while the other side is placed on the away side 266. As shown by the arrow in Fig. 12, the light emitted from the light-emitting diode 250 is incident on the inside of the second lens 652 through the light incident surface 6520, and is further emitted from the light exit surface 6522 of the second lens 652. When the light exits from the light exit surface 6522, the light exit surface 6522 is refracted such that the light is deflected away from the side 266. Therefore, the light intensity at the driving away from side 266 is relatively large, and the light intensity at the approaching side 265 of the driving is relatively weak. By adjusting the curvature of the light emitting surface 6522 of the second lens 652, the light source illuminates the light of the road surface 22 on the road surface. 22 extends in the X direction to the vehicle away from the side 266 by a predetermined angle. The action of the lens 6210 in the first light source 651 is the same as that of the lens 251 in the light source 25, and as shown by the arrow in FIG. 11, the light emitted by the light-emitting diode 250 is emitted from the first lens 6510, and is offset from the central axis. The predetermined range is such that light having a greater light intensity in the direction of the ridge extending in the vertical road surface 22 is located on both sides of the glare region, and the light intensity of the light in the glare region is relatively weakened, thereby preventing glare from being directed toward the vehicle or driving Direct glare from the staff. FIG. 13 is a view showing a light source of a lamp 21 according to a sixth embodiment of the present invention, which is different from the fifth embodiment in that the structure of the lens 7521 in the second light source 752 is different. The lens 7521 includes a rectangular body portion 099103546 Form No. Α0101 Page 13 of 38 0992006659-0 201128109 7520 and an optical portion 7522 formed at the center of the top surface 7523 of the main body portion 7520. The outer surface 7524 of the optical portion 7522 is a spherical surface that is convex away from the main body portion 7520. The thickness of the optical portion 7522 is gradually increased from one side of the second light source 725 to the other side, that is, the optical portion 75. The distance between the outer surface 7524 of the 2 2 and the top surface 7523 of the body portion 7520 gradually increases from one side to the other side. The bottom surface of the main body portion 7520 is recessed in a direction away from the top surface of the side of the optical portion 7522 which is smaller in thickness to form a space 7525 for accommodating the light-emitting diode 250. As shown by the arrow in Fig. 13, the light emitted from the position of the light-emitting diode 25 is different from the center of the light-emitting diode 25, and the light emitted from the light-emitting diode 25 is incident on the permeable beam, and the line is made by the optical portion 7 5 2 When the outer surface 7524 of the second surface 2 is emitted, the outer surface 7524 is refracted so that the light is deflected by one side toward the side of the optical portion 7522 having a larger thickness. When used, the side of the optical portion 7522 of the lens 7521 having a larger thickness is placed on the traveling away side 266. The light emitted through the lens 7521 is deflected toward the traveling away side 266, and therefore, the light intensity at the traveling away side 266. The light intensity is relatively small, and the light intensity on the approaching side 265 is weak. By adjusting the curvature of the outer surface 7524 of the optical portion 7522, the light illuminating the road surface 22 by the light source can be driven away from the side 2 in the X direction in which the road surface 22 extends. 6 6 deflected by a predetermined angle. 14 is a light source of a luminaire 21 according to a seventh embodiment of the present invention. The difference from the fifth embodiment is that the structure of the lens 8521 in the second light source 852 is different. The lens 8521 has a plate-like profile, and includes a light-incident surface 8520 and a light-emitting surface 8522 opposite to the light-incident surface 852. The lens 8521 is located above the light-emitting diode 25A, and the light-incident surface 8520 is planar and disposed adjacent to the light-emitting diode 25A. The light-emitting surface 8522 does not have a plurality of zigzag-shaped protrusions 8523. Each protrusion 8523 099103546 Form No. A0101 Page 14 of 38 0992006659-0 201128109 包括 A vertical surface 8525 and an inclined surface 8524 connecting the vertical surface 8525 are included. Wherein, the vertical faces 8525 are parallel to each other, respectively perpendicular to the light incident surface 8520, and the inclined faces 8524 are obliquely extended and connected to the vertical faces 8525 of the adjacent sides thereof. As shown by the arrow in FIG. 14, the light emitted from the LED 230 is incident on the lens 8521 through the light incident surface 8520, and is refracted when the light is emitted through the vertical surface 8525 or the inclined surface 8522 on the light exit surface 8522, and is directed toward the corresponding protrusion. The side of the vertical face 8525 of the 8523 is partially deflected. In use, the luminaire 21 is mounted such that the vertical face 8525 of the projection 8523 in the lens 8521 is placed on the side of the vehicle away from the side 266. Thus, the light exiting through the lens 8521 is deflected toward the away side 266. By adjusting the slope of the inclined surface 8524 in the protrusion 8523, the light of the light source impinging on the road surface 22 can be deflected to a predetermined distance from the side 266 away from the side 266 in the X direction in which the road surface 22 extends. [0019] Finally, the lenses 251, 351, 451 in the light sources 25, 35, Ο 45 in the first, second, and third embodiments can be used to change the light emitted by the LEDs 250, respectively. The range in which the light having a large light intensity is concentrated is such that the light emitted from the light-emitting diode 250 is deflected toward the side to form a light distribution curve of the airfoil, and therefore, the light that the lamp 21 illuminates the road surface 22 extends on the vertical road surface 22. In the Y direction, by determining the relative position of the luminaire 21 and the eye of the driver of the vehicle traveling on the road surface 22, the light having a relatively large light intensity that is laterally offset is located outside the glare region, and the light intensity in the glare region. Attenuate, thereby avoiding direct glare caused by strong light directly illuminating the vehicle or the driver. When the luminaire 21 is used as a luminaire in the tunnel 20, a part of the ray in the Y direction extending perpendicular to the road surface 22 is incident on the inner wall surface 23 of the tunnel 20 after diffuse reflection or diffusion emission, and then uniformly 099103546 form nickname A0101 15 pages/total 38 pages 0992006659-0 201128109 [0020] [0023] 099103546 exits to the road surface 22' to form a uniform illumination environment. The second light source, 652, 752 and the off-going lenses 6521, 7521, 8521 in the fifth, sixth and seventh embodiments, respectively, can be used to change the outgoing direction of the light emitted by the light-emitting diode 25, thereby enabling the light fixture The light illuminating the road surface 22 is deflected toward the driving away side 266 along the X direction in which the road surface 22 extends. When the driver is traveling on the road surface 22 on the approaching side 265, the light stimulation of the eye does not exceed the normal range, and thus It will be affected by direct glare'. When the car is approaching the side 2 6 5 and driving away from the side 266, the driver is facing away from the direction of light, and it is not affected by direct glare. In a specific implementation, the luminaire 21 may include a combination of other different light sources to achieve the above-mentioned purpose of avoiding direct glare. For example, the luminaire 21 may include the light sources μ, 35, 45 in the first, second, and third embodiments described above. Any combination of the middle light emitting diode 25A and the lenses 251, 351, 451 is used in combination with any of the second light sources 652, 752, 852 in the fifth, sixth, and seventh embodiments to avoid driving The person is affected by direct glare while driving on the road surface 22.
