以下係提出實施例進行詳細說明，實施例僅用以作為範例說明，並非用以限縮本發明欲保護之範圍。以下是以相同/類似的符號表示相同/類似的元件做說明。 The following examples are provided for detailed description. The examples are only used as examples for description, and are not intended to limit the scope of the present invention. In the following description, the same/similar symbols represent the same/similar elements.

請參照第1A及1B圖之照明裝置100，其包括一燈具110以及一遮光罩120。燈具110具有一前燈罩112以及一發光 元件114，前燈罩112具有一出光表面113。遮光罩120至少部分覆蓋出光表面113，用以降低燈具110出射的光能或過濾部分光波段，使遮光罩120的透光度小於一預設值。一般而言，發光元件114設置於燈具110內並由前燈罩112所保護，發光元件114通常會遠離前燈罩112。發光元件114例如是發光二極體陣列元件或其他發光源。 Please refer to the lighting device 100 in FIGS. 1A and 1B, which includes a lamp 110 and a light shield 120. The lamp 110 has a front lampshade 112 and a light emitting The element 114 and the front lamp cover 112 have a light emitting surface 113. The light-shielding cover 120 at least partially covers the light-emitting surface 113 to reduce the light energy emitted by the lamp 110 or filter a part of the light waveband so that the light transmittance of the light-shielding cover 120 is less than a preset value. Generally speaking, the light-emitting element 114 is disposed in the lamp 110 and protected by the front light cover 112, and the light-emitting element 114 is usually away from the front light cover 112. The light-emitting element 114 is, for example, a light-emitting diode array element or other light-emitting source.

在一實施例中，遮光罩120的周圍121與燈具110的周圍111相對應接合，可以鎖固或卡固的方式將遮光罩120固定在燈具110上。又或在部份的實施例中，遮光罩120的內表面S1可與前燈罩112的出光表面113接合，例如可以黏膠方式使內表面S1固著於出光表面113上、以抽真空貼合的方式使內表面S1附著在出光表面113上。較佳地，遮光罩120與前燈罩112係完全密閉，更佳係遮光罩120與前燈罩112完全貼合，以避免水氣進入並殘留其中。 In an embodiment, the periphery 121 of the light shield 120 and the periphery 111 of the lamp 110 are correspondingly engaged, and the light shield 120 can be fixed on the lamp 110 in a locking or clamping manner. Or in some embodiments, the inner surface S1 of the light shield 120 can be joined with the light-emitting surface 113 of the headlight cover 112, for example, the inner surface S1 can be fixed on the light-emitting surface 113 by means of glue, and then attached by vacuum. The way makes the inner surface S1 adhere to the light exit surface 113. Preferably, the light shield 120 and the front light cover 112 are completely sealed, and more preferably, the light shield 120 and the front light cover 112 are completely attached to prevent moisture from entering and remaining therein.

遮光罩120例如是呈拱形的弧形結構，可配合前燈罩112的外型(例如弧形)，以使遮光罩120的形狀與被覆蓋的前燈罩112的出光表面113的形狀互相配合。此外，在另一未繪示的實施例中，遮光罩120例如為一平板結構，以配合前燈罩112的外型(例如平面型)。 The shading cover 120 is, for example, an arched arc structure, which can match the shape (for example, an arc) of the front lamp cover 112 so that the shape of the shading cover 120 and the shape of the light exit surface 113 of the covered front lamp cover 112 match each other. In addition, in another unillustrated embodiment, the light shield 120 is, for example, a flat plate structure to match the shape of the front lamp cover 112 (for example, a plane type).

在一實施例中，遮光罩120係根據所欲改善的照明區域來覆蓋對應部分的出光表面113，例如覆蓋出光表面113的前部、後部或前部及後部，用以降低由出光表面113的前部及/或後 部出射的光能或過濾部分光波段。如第1B圖所示，遮光罩120覆蓋位於出光表面113前部的一第一出光區F。如第2圖所示，遮光罩120覆蓋位於出光表面113後部的一第二出光區R。如第3圖所示，遮光罩120的中央具有一開口O，與燈具110的中央出光區M相對，遮光罩120覆蓋位於出光表面113前部及後部的第一出光區F以及第二出光區R，其中第一出光區F與第二出光區R位於燈具110之中央出光區M的相對兩側。除此之外，遮光罩120亦可完全覆蓋出光表面113(如第4圖所示)。因此，遮光罩120可依照明條件而調整覆蓋出光表面113的面積。 In one embodiment, the light-shielding cover 120 covers the corresponding part of the light-emitting surface 113 according to the lighting area to be improved, for example, covering the front, rear, or front and rear of the light-emitting surface 113 to reduce the light-emitting surface 113 Front and/or rear Part of the emitted light energy or filter part of the light band. As shown in FIG. 1B, the light-shielding cover 120 covers a first light-emitting area F located in front of the light-emitting surface 113. As shown in FIG. 2, the light-shielding cover 120 covers a second light-emitting area R located behind the light-emitting surface 113. As shown in Figure 3, the light shield 120 has an opening O in the center, which is opposite to the central light exit area M of the lamp 110. The light shield 120 covers the first light exit area F and the second light exit area located at the front and rear of the light exit surface 113 R, where the first light-emitting area F and the second light-emitting area R are located on opposite sides of the central light-emitting area M of the lamp 110. In addition, the light shield 120 can also completely cover the light exit surface 113 (as shown in FIG. 4). Therefore, the light shield 120 can adjust the area covering the light exit surface 113 according to the bright conditions.

如第1B、2或3圖所示，燈具110使用遮光罩120之後，可使燈具110前方及/或後方的出光量小於燈具110中央的出光量，因此燈具110中央的亮度最高，以提高路面的照度，此外，燈具110前方及/或後方的亮度較低，可減少光害或避免雜散光直接入射人眼而造成直接眩光。另外，遮光罩120為透光的材質，而非金屬遮光罩或反射性高的材質，因此可避免反射光線，並可避免部分光能反射至燈具110內轉換成熱能後累積在燈具110內而造成高溫，影響燈具110的性能。 As shown in Figures 1B, 2 or 3, after the lamp 110 uses the hood 120, the light output from the front and/or back of the lamp 110 can be less than the light output from the center of the lamp 110, so the center of the lamp 110 has the highest brightness to improve the road surface In addition, the front and/or rear brightness of the lamp 110 is relatively low, which can reduce light damage or prevent stray light from directly entering human eyes and causing direct glare. In addition, the light-shielding cover 120 is made of a light-transmitting material instead of a metal light-shielding cover or a highly reflective material, so it can avoid reflecting light, and can prevent part of the light energy from being reflected into the lamp 110 and converted into heat energy and then accumulated in the lamp 110. It causes high temperature and affects the performance of the lamp 110.

在一實施例中，遮光罩120覆蓋出光表面113的面積的比值例如為5%~100%之間，較佳為30%~80%之間，更佳為40%~60%之間，依情況而調整比值。此外，遮光罩120覆蓋出光表面113的第一出光區F的面積與第二出光區R的面積大小可相同或不相同，例如遮光罩120覆蓋出光表面113的第一出光區F的 面積可大於或小於遮光罩120覆蓋出光表面113的第二出光區R的面積，藉以調整照明裝置100的出光光型。 In an embodiment, the ratio of the area of the light-shielding mask 120 covering the light-emitting surface 113 is, for example, between 5% and 100%, preferably between 30% and 80%, more preferably between 40% and 60%, depending on Adjust the ratio according to the situation. In addition, the light-shielding cover 120 covers the area of the first light-emitting area F of the light-emitting surface 113 and the area of the second light-emitting area R may be the same or different. For example, the light-shielding cover 120 covers the first light-emitting area F of the light-emitting surface 113. The area may be larger or smaller than the area of the second light exit region R of the light exit surface 113 covered by the light shield 120, so as to adjust the light exit type of the lighting device 100.

在照本發明之一實施例中，遮光罩包括一殼體以及一染料。殼體由一透明材質製成，殼體具有相對的一內表面以及一外表面。染料位於殼體內，以使遮光罩的透光度小於一預設值。在一實施例中，殼體122例如是由高分子材料所製成，其包括聚碳酸酯(Polycarbonate,PC)、聚甲基丙烯酸甲酯(poly(methyl methacrylate)，PMMA)、矽膠(polymerized siloxanes，俗稱silicone)、聚苯乙烯(Polystyrene，PS)、聚丙烯(Polypropylene，PP)、聚乙烯(polyethylene，PE)及丙烯腈丁二烯苯乙烯(Acrylonitrile Butadine Styrene，ABS)中的至少一種高分子材料。殼體122可回收再利用。殼體122的硬度例如介於洛氏硬度85-95之間。 In an embodiment according to the present invention, the light shield includes a housing and a dye. The shell is made of a transparent material, and the shell has an inner surface and an outer surface opposite to each other. The dye is located in the shell, so that the transmittance of the light shield is less than a preset value. In an embodiment, the housing 122 is made of, for example, a polymer material, which includes polycarbonate (PC), poly(methyl methacrylate) (PMMA), and polymerized siloxanes. , Commonly known as silicone, polystyrene (Polystyrene, PS), polypropylene (Polypropylene, PP), polyethylene (polyethylene, PE) and acrylonitrile butadiene styrene (Acrylonitrile Butadine Styrene, ABS) at least one polymer material. The shell 122 can be recycled and reused. The hardness of the housing 122 is, for example, between 85-95 Rockwell hardness.

本實施例之遮光罩120於殼體122內添加染料123，使遮光罩120的透光度小於一預設值，例如介於50%至95%之間。也就是說，遮光罩120可藉由添加的染料123阻擋部分光或濾除部分光波段，以使遮光罩120的透光度小於一預定值。遮光罩120的透光度與添加的染料123的濃度呈負相關，當添加的染料123的濃度增加時，遮光罩120的透光度相對減少。在一實施例中，染料123於殼體122內的濃度百分比例如小於等於4%，大於等於0%，但染料123於殼體122內的濃度可依照明條件而調整，不限定小於等於4%。此外，染料123於殼體122內的具有濃度變 化。例如可染料123的濃度可由殼體122的周圍往其中央遞減，使殼體122的透光度由殼體122的周圍往中央依序遞增/遞減，或者可朝一方向(例如上下方向或左右方向)遞增/遞減，也就是說，可使遮光罩120某一區域的透光度較高，以維持高的照度，但使其他區域的透光度較低，以降低光害。 In the light shield 120 of this embodiment, a dye 123 is added to the housing 122 to make the light transmittance of the light shield 120 less than a preset value, for example, between 50% and 95%. In other words, the light shield 120 can block part of the light or filter out part of the light waveband by adding the dye 123, so that the light transmittance of the light shield 120 is less than a predetermined value. The light transmittance of the light shield 120 is negatively correlated with the concentration of the added dye 123. When the concentration of the added dye 123 increases, the light transmittance of the light shield 120 relatively decreases. In one embodiment, the concentration percentage of the dye 123 in the housing 122 is, for example, less than or equal to 4%, and greater than or equal to 0%, but the concentration of the dye 123 in the housing 122 can be adjusted according to specific conditions and is not limited to less than or equal to 4%. . In addition, the dye 123 in the housing 122 has a concentration change 化. For example, the concentration of the dye 123 may decrease from the periphery of the housing 122 to its center, so that the transmittance of the housing 122 increases/decreases sequentially from the periphery of the housing 122 to the center, or it may move in one direction (for example, up and down or left and right). ) Increasing/decreasing, that is, the transmittance of a certain area of the light shield 120 can be made higher to maintain high illuminance, but the transmittance of other areas can be made lower to reduce light damage.

在本發明中染料123可的顏色不限，染料123的成份可為有機化合物，例如是(2-[[5-(2,4-二氯苯基)呋喃-2-基]亞甲基]-5-(4-甲氧基苯基)-7-甲基-3-氧代-5H-[1,3]噻唑並[3，2-a]嘧啶-6-甲酸乙酯)，ethyl 2-[[5-(2,4-dichlorophenyl)furan-2-yl]methylidene]-5-(4-methoxyphenyl)-7-methyl-3-oxo-5H-[1,3]thiazolo[3,2-a]pyrimidine-6-carboxylate。 In the present invention, the color of dye 123 is not limited, and the component of dye 123 may be an organic compound, such as (2-[[5-(2,4-dichlorophenyl)furan-2-yl]methylene] -5-(4-methoxyphenyl)-7-methyl-3-oxo-5H-[1,3]thiazolo[3,2-a]pyrimidine-6-ethyl carboxylate), ethyl 2 -[[5-(2,4-dichlorophenyl)furan-2-yl]methylidene]-5-(4-methoxyphenyl)-7-methyl-3-oxo-5H-[1,3]thiazolo[3,2- a]pyrimidine-6-carboxylate.

此外，遮光罩120的外表面S2例如為一平滑表面，以避免污染物附著在遮光罩120的外表面S2。為增加抗污效果，更可形成一奈米塗層126於殼體122的外表面S2(參見第4圖)。奈米塗層126可有效隔離PM2.5等級之油性與非油性粒狀汙染物，達到抗污且外表面S2不易附著污染物的效果。在一實施例中，奈米塗層126可為奈米二氧化鈦-二氧化矽光觸媒薄膜，可有效分解有機物。 In addition, the outer surface S2 of the light shield 120 is, for example, a smooth surface, so as to prevent contaminants from adhering to the outer surface S2 of the light shield 120. In order to increase the anti-fouling effect, a nano-coating 126 can be formed on the outer surface S2 of the housing 122 (see FIG. 4). The nano-coating 126 can effectively isolate the oily and non-oily particulate pollutants of PM2.5 grade, and achieve the effect of anti-fouling and the outer surface S2 is not easy to adhere to the pollutants. In one embodiment, the nano-coating 126 may be a nano-titanium dioxide-silica photocatalyst film, which can effectively decompose organic matter.

遮光罩120除了藉由染料123改變透光度之外，遮光罩120的殼體122的內表面S1例如具有柔光微結構124，可改變出光角度。請參照第4圖，柔光微結構124例如為透鏡陣列，其一體成形於殼體122的內表面S1。此外，在部份實施例中，內表面 S1與前燈罩112的出光表面113相鄰且相隔一間距，可使空氣流通於該間隙中，以促進散熱。在本發明中，間距的寬度較佳係小於遮光罩厚度，以避免外物飛入間隙並殘留其中。 In addition to changing the light transmittance of the light shield 120 by the dye 123, the inner surface S1 of the housing 122 of the light shield 120 has, for example, a soft light microstructure 124, which can change the light output angle. Please refer to FIG. 4, the soft light microstructure 124 is, for example, a lens array, which is integrally formed on the inner surface S1 of the housing 122. In addition, in some embodiments, the inner surface S1 is adjacent to the light emitting surface 113 of the headlight cover 112 and is separated by a distance, so that air can circulate in the gap to promote heat dissipation. In the present invention, the width of the gap is preferably smaller than the thickness of the light shield to prevent foreign objects from flying into the gap and remaining therein.

請參照第5圖，光線L1通過柔光微結構124之後改變出光角度，以使光線L1朝不同的方向前進並成為發散光L2，因此在第4圖中發光元件114的光線L於X軸方向上的出光角度變大且均勻出光，以提高均一性。 Please refer to Fig. 5, after the light L1 passes through the soft light microstructure 124, the light exit angle is changed, so that the light L1 advances in different directions and becomes divergent light L2. Therefore, in Fig. 4, the light L of the light-emitting element 114 is in the X-axis direction The light emitting angle on the upper side becomes larger and the light is emitted uniformly to improve the uniformity.

請參照第5及6圖，在一實施例中，柔光微結構124例如包括多個柱狀透鏡125，其長度沿著內表面S1延伸，柱狀透鏡125於燈具110的短軸方向(即Y軸方向)上呈長條狀，並於燈具110的長軸方向(即X軸方向)上平行排列。請參照第7圖，在另一實施例中，柔光微結構124例如包括多個半圓形透鏡127，其排列於殼體122的內表面S1，以達到霧化或均勻化出光的效果。 Referring to FIGS. 5 and 6, in an embodiment, the soft light microstructure 124 includes a plurality of cylindrical lenses 125, the length of which extends along the inner surface S1, and the cylindrical lenses 125 are located in the short axis direction of the lamp 110 (ie It is elongated in the Y-axis direction and arranged in parallel in the long-axis direction of the lamp 110 (ie, the X-axis direction). Referring to FIG. 7, in another embodiment, the soft light microstructure 124 includes, for example, a plurality of semicircular lenses 127 arranged on the inner surface S1 of the housing 122 to achieve the effect of atomization or uniform light emission.

綜上所述，雖然本發明已以實施例揭露如上，然其並非用以限定本發明。本發明所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作各種之更動與潤飾。因此，本發明之保護範圍當視後附之申請專利範圍所界定者為準。 In summary, although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Those who have ordinary knowledge in the technical field to which the present invention belongs can make various changes and modifications without departing from the spirit and scope of the present invention.
