Description

照明器具及使用此照明器具之照明器具單元 Lighting fixture and lighting fixture unit using the same

本發明係關於一種照明器具及使用此照明器具之照明器具單元，其控制來自LED光源的照射。 The present invention relates to a lighting fixture and a lighting fixture unit using the lighting fixture that controls illumination from an LED light source.

近年來，從節能化及減少保養化等觀點而言，於屋外照明，或於高塔及橋樑等建築物之景觀照明及裝飾照明上使用發光二極體(以下稱LED)作為光源。但是，因為LED光源係點光源而發光面小，所以有人提案出一種藉由設置反射體來擴大發光面的照明裝置(例如日本特開第2010-153400號公報)。 In recent years, from the viewpoints of energy saving and maintenance reduction, a light-emitting diode (hereinafter referred to as LED) is used as a light source for outdoor lighting or for landscape lighting and decorative lighting of buildings such as towers and bridges. However, since the LED light source is a point light source and the light-emitting surface is small, an illumination device in which a light-emitting surface is enlarged by providing a reflector has been proposed (for example, Japanese Laid-Open Patent Publication No. 2010-153400).

習知的照明裝置具有將平板折彎成U字形狀的反射體，在反射體的峰上設置有多數之LED發光元件來作為光源。藉由此種構成，上述習知的照明裝置可擴大發光面，將光線照射至廣範圍。 A conventional illumination device has a reflector that bends a flat plate into a U shape, and a plurality of LED light-emitting elements are provided on a peak of the reflector as a light source. With such a configuration, the above-described conventional illumination device can enlarge the light-emitting surface and illuminate the light to a wide range.

以橋樑及高塔等的裝飾照明為目的來使用照明裝置時，係使用非常高功率的LED光源，使得放射的光線從遠方亦能視認。 When lighting devices are used for decorative lighting such as bridges and towers, a very high-power LED light source is used, so that the emitted light can be viewed from a distance.

但是，即使在使用高功率LED光源之情形下，也因為發光面小，所以難確保從長距離的視認性。又，因為從光源開始的發光方向即受到限制， 所以可視角狹窄。 However, even in the case of using a high-power LED light source, since the light-emitting surface is small, it is difficult to ensure visibility from a long distance. Also, since the direction of illumination from the light source is limited, Therefore, the viewing angle is narrow.

另一方面，此種高功率的光源，有些情況下，尤其是在通過橋樑附近上空的航空器或者通過橋樑下的船舶之駕駛員直視時，會暫時性地降低該駕駛員的視力。因此，將具有高功率光源的照明裝置安裝於橋樑時，有些情況下要求朝向特定方向進行照射。亦即，從照明裝置放射的光線之垂直方向的發射角受到限制，以免降低例如通過橋樑附近的航空器或船舶之駕駛員的視力。 On the other hand, such a high-power light source, in some cases, temporarily reduces the driver's vision, especially when looking through the aircraft in the vicinity of the bridge or through the driver of the ship under the bridge. Therefore, when an illuminating device having a high-power light source is mounted on a bridge, it is sometimes required to illuminate in a specific direction. That is, the emission angle in the vertical direction of the light emitted from the illumination device is limited so as not to reduce the vision of the driver, for example, through an aircraft or a ship near the bridge.

為了擴大發光面，可使用上述習知的照明裝置之構成，或藉由透鏡來擴大發光面並擴大可視角。其中，藉由透鏡來擴大發光面時，透鏡巨大化且製造費提高。又，使用上述習知的照明裝置之構成時，難以限制放射的光線之垂直方向的擴大，又，因為光線從靠近光源的位置擴散，所以有欠缺從長距離的視認性之問題。 In order to enlarge the light-emitting surface, the configuration of the above-described conventional illumination device may be used, or the light-emitting surface may be enlarged by a lens and the viewing angle may be enlarged. Among them, when the light-emitting surface is enlarged by a lens, the lens is enlarged and the manufacturing cost is increased. Moreover, when the configuration of the above-described conventional illumination device is used, it is difficult to restrict the enlargement of the vertical direction of the emitted light, and since the light is diffused from the position close to the light source, there is a problem that the visibility from the long distance is lacking.

本發明之目的在於提供一種照明器具及照明器具單元，可將LED光源的光線朝特定方向照射渡過長距離。 It is an object of the present invention to provide a lighting fixture and a lighting fixture unit that can illuminate a light source of an LED light source in a specific direction over a long distance.

(實施發明之較佳形態) (Preferred form of implementing the invention) (實施形態1) (Embodiment 1)

以下使用圖式說明實施形態1的照明器具與使用此照明器具之照明器具單元。 Hereinafter, the lighting fixture of the first embodiment and the lighting fixture unit using the lighting fixture will be described with reference to the drawings.

圖1係使用有實施形態1之照明器具單元的橋樑2。橋樑2係固定於既定位置的結構物。如圖1所示藉由2個主塔3、1組主纜線4、從主纜線4垂直垂下的多數之吊索5來支持椼架6。1組主纜線4架設於主塔3，分別位於椼架6的短邊方向兩端。圖2係顯示圖1的橋樑2之部分A的部分放大圖。如圖2所示，照明器具單元1設於吊索5的前端附近。橋樑2的多數之吊索5各設有照明器具單元1。照明器具單元1設為朝向橋樑2的外側往水平方向照射光線。亦即，照明器具單元1係設於橋樑2，以各照明器具10的開口面171(參照圖4)側作為正面，並使得照明器具單元1的正面朝向橋樑2的外側。 Fig. 1 shows a bridge 2 using the lighting fixture unit of the first embodiment. The bridge 2 is a structure fixed to a predetermined position. As shown in Fig. 1, the truss 6 is supported by two main towers 3, a group of main cables 4, and a plurality of slings 5 vertically hanging from the main cable 4. One set of main cables 4 is erected on the main tower 3. , respectively located at the ends of the short side of the truss 6. 2 is a partial enlarged view showing a portion A of the bridge 2 of FIG. 1. As shown in FIG. 2, the lighting fixture unit 1 is provided near the front end of the sling 5. The slings 5 of the bridge 2 are each provided with a lighting fixture unit 1. The luminaire unit 1 is configured to illuminate the light in the horizontal direction toward the outside of the bridge 2. That is, the lighting fixture unit 1 is attached to the bridge 2, and the side of the opening surface 171 (see FIG. 4) of each lighting fixture 10 is the front surface, and the front surface of the lighting fixture unit 1 is directed to the outer side of the bridge 2.

圖3A、3B顯示實施形態1之照明器具單元1，圖3A係照明器具單元1的側面圖，圖3B係照明器具單元1的正面圖。實施形態1之照明器具單元1具有3個照明器具10。照明器具10分別藉由安裝基台(未圖示)來固定於照明器具單元1的本體。另，設於照明器具單元1的照明器具10之數量不限於3個，亦可係1個或多數個。照明器具單元1安裝構件7固定於吊索5，俾往水平方向照射光線。 3A and 3B show a lighting fixture unit 1 according to the first embodiment, Fig. 3A is a side view of the lighting fixture unit 1, and Fig. 3B is a front view of the lighting fixture unit 1. The lighting fixture unit 1 of the first embodiment has three lighting fixtures 10. The lighting fixture 10 is fixed to the main body of the lighting fixture unit 1 by a mounting base (not shown). Further, the number of the lighting fixtures 10 provided in the lighting fixture unit 1 is not limited to three, and may be one or a plurality. The luminaire unit 1 mounting member 7 is fixed to the sling 5, and illuminates the light in the horizontal direction.

如此於橋樑2安裝多數照明器具單元1，用於裝飾照明等目的。將照明器具單元1使用作為裝飾照明之目的時，於照明器具單元1使用高功率的光源，使得從照明器具單元1放射的光線即使從遠方也能視認。 In this way, a plurality of lighting fixture units 1 are mounted on the bridge 2 for decorative lighting purposes and the like. When the lighting fixture unit 1 is used for decorative lighting purposes, a high-power light source is used in the lighting fixture unit 1, so that the light emitted from the lighting fixture unit 1 can be visually recognized even from a distance.

但是，將LED用於光源時，因為發光面窄小所以直視下從長距離難確保視認性。又因為從光源開始的發光方向即受到限制，所以可視角狹窄。 However, when an LED is used for a light source, since the light-emitting surface is narrow, it is difficult to ensure visibility from a long distance under direct view. Moreover, since the direction of light emission from the light source is limited, the viewing angle can be narrow.

又，此種高功率的光源，有些情況下，在通過橋樑2附近上空的航空 器獲通過橋樑2下的船舶之駕駛員直視時，會暫時性地降低該駕駛員的視力。因此，在將具有高功率的光源之照明器具單元1安裝於橋樑2時，限制從照明器具單元1放射的光線之垂直方向的發射角，以免降低通過橋樑2附近的航空器或船舶之駕駛員的視力。亦即，從照明器具單元1往垂直方向放射的光線受到限制。所以照明器具單元1在橋樑2設置成往大致前方放射光線。在此「前方」係在橋樑2設置照明器具單元1時，照明器具單元1照射光線的方向，在實施形態1中係指大致水平方向。 Also, such a high-power light source, in some cases, is in the air above the bridge 2 When the driver is directly looking through the driver of the ship under the bridge 2, the driver's vision is temporarily lowered. Therefore, when the lighting fixture unit 1 having a high-power light source is attached to the bridge 2, the emission angle in the vertical direction of the light emitted from the lighting fixture unit 1 is restricted so as not to reduce the driver of the aircraft or the ship passing near the bridge 2. vision. That is, the light emitted from the lighting fixture unit 1 in the vertical direction is restricted. Therefore, the lighting fixture unit 1 is disposed on the bridge 2 to radiate light substantially forward. Here, in the "front", when the luminaire unit 1 is installed in the bridge 2, the direction in which the luminaire unit 1 is irradiated with light is referred to as a substantially horizontal direction in the first embodiment.

本發明的照明器具10解決了上述問題。圖4係實施形態1中的照明器具10之立體圖。照明器具10具有：LED光源11；框體12，收容LED光源11；以及控制點亮部(控制部)9(參照圖3A)，與LED光源11電性連接並控制點亮LED光源11。框體12具有在框體12的長邊方向(第1方向)上彼此對向的第1側面(第1面)13及第2側面(第2面)14，並具有底面(第3面)15、頂面(第5面)16及背面(第4面)19。底面15將第1側面13與第2側面14加以連結。背面19連接於底面15，並將第1側面13與第2側面14加以連結。頂面16連接於背面19，並將第1側面13與第2側面14加以連結。其中，在實施形態1中，頂面16與背面19平順地連接設為一體。又，頂面16連接於背面19，並與底面15對向。框體12具有開口部17，開口部17受到第1側面13、第2側面14、底面15及頂面16所圍繞。開口部17與背面19對向。框體12形成為以第1側面13與第2側面14所對向的方向為長邊方向(第1方向)。底面15形成為平面，LED光源11係設於底面15。底面15形成為在框體12的長邊方向上細長的矩形形狀，將第1側面13與第2側面14在長邊方向加以連結。於框體12的內側面(位於框體12內側的面)，亦即於各第1側面13、第2側面14、底面15、頂面16、背面19設有反射部18。反射部18，例如進行鏡面加工，藉以使入射的光線鏡面反射。 The lighting fixture 10 of the present invention solves the above problems. Fig. 4 is a perspective view of the lighting fixture 10 in the first embodiment. The lighting fixture 10 includes an LED light source 11 , a housing 12 that houses the LED light source 11 , and a lighting unit (control unit) 9 (see FIG. 3A ) that is electrically connected to the LED light source 11 and controls the LED light source 11 to be lit. The frame body 12 has a first side surface (first surface) 13 and a second side surface (second surface) 14 that face each other in the longitudinal direction (first direction) of the casing 12, and has a bottom surface (third surface). 15. Top surface (5th surface) 16 and back surface (4th surface) 19. The bottom surface 15 connects the first side surface 13 and the second side surface 14 . The back surface 19 is connected to the bottom surface 15, and the first side surface 13 and the second side surface 14 are coupled to each other. The top surface 16 is connected to the back surface 19, and the first side surface 13 and the second side surface 14 are coupled to each other. In the first embodiment, the top surface 16 and the back surface 19 are smoothly connected to each other. Further, the top surface 16 is connected to the back surface 19 and faces the bottom surface 15. The casing 12 has an opening 17 which is surrounded by the first side face 13, the second side face 14, the bottom face 15, and the top face 16. The opening 17 faces the back surface 19. The frame body 12 is formed such that the direction in which the first side surface 13 and the second side surface 14 face each other is the longitudinal direction (first direction). The bottom surface 15 is formed as a flat surface, and the LED light source 11 is attached to the bottom surface 15. The bottom surface 15 is formed in a rectangular shape elongated in the longitudinal direction of the casing 12, and the first side surface 13 and the second side surface 14 are coupled in the longitudinal direction. The reflection portion 18 is provided on the inner side surface of the frame body 12 (the surface on the inner side of the frame body 12), that is, on each of the first side surface 13, the second side surface 14, the bottom surface 15, the top surface 16, and the back surface 19. The reflecting portion 18 is, for example, mirror-finished, whereby the incident light is specularly reflected.

藉由此種構成，因為可以擴大照明器具10的發光面，且往特定方向放射光線，所以能確保從長距離的視認性。又，因為藉由使用反射部18代替透鏡來擴大發光面，所以能夠比使用透鏡時更便宜地製造。 According to this configuration, since the light-emitting surface of the lighting fixture 10 can be enlarged and the light is radiated in a specific direction, visibility from a long distance can be ensured. Moreover, since the light-emitting surface is enlarged by using the reflection portion 18 instead of the lens, it can be manufactured more cheaply than when the lens is used.

在圖3A、3B所示的照明器具單元1中，3個照明器具10排列於與各者之長邊方向(第1方向)正交的方向(第2方向)。將與第1方向及第2方向均正交的方向定為第3方向。又，3個照明器具10各者之開口部17配置成往相同方向開口。藉由如此配置3個照明器具10，能達成照明器具單元1全體大小的小型化。另，3個照明器具10的開口部17所開口的方向係沿著第3方向的方向。尤其，3個照明器具10的開口部17所開口的方向宜係第3方向。 In the lighting fixture unit 1 shown in FIGS. 3A and 3B, the three lighting fixtures 10 are arranged in a direction (second direction) orthogonal to the longitudinal direction (first direction) of each. The direction orthogonal to both the first direction and the second direction is defined as the third direction. Further, the openings 17 of the three lighting fixtures 10 are arranged to open in the same direction. By arranging the three lighting fixtures 10 as described above, it is possible to achieve downsizing of the entire size of the lighting fixture unit 1. Further, the direction in which the opening 17 of the three lighting fixtures 10 is opened is in the direction along the third direction. In particular, the direction in which the opening 17 of the three lighting fixtures 10 is opened is preferably the third direction.

排列有3個照明器具10的照明器具單元1係沿著放射光線的特定方向在水平面從橋樑2朝向外側的方向設置於橋樑2。又，照明器具單元1於橋樑2設置成各照明器具10的底面15比頂面16更下側。 The luminaire unit 1 in which the three luminaires 10 are arranged is provided on the bridge 2 in a direction from the bridge 2 toward the outside in a specific direction of the ray. Further, the lighting fixture unit 1 is disposed on the bridge 2 such that the bottom surface 15 of each lighting fixture 10 is lower than the top surface 16.

以下說明實施形態1之照明器具10的細節。圖5係圖4所示的照明器具10之線段A-A的剖面圖。如圖5所示，框體12的內側中，頂面16與背面19係平順地連接且具有共通的曲面，該共通的曲面所與垂直於開口部17之開口面171及底面15的面之交線係拋物線。亦即，頂面16及背面19具有共通的曲面，該共通的曲面所與法線在長邊方向(第1方向)上的面之交線係拋物線。頂面16及背面19形成有各自的曲面，使得該拋物線的焦點在框體12內。又如上所述地在頂面16與背面19設有反射部18。LED光源11希望位於頂面16及背面19的拋物線之焦點。因為LED光源11係放射狀發出光線，所以藉由將LED光源11設置於頂面16及背面19的拋物線之焦點，照明器具10可將LED光源11的發光往固定方向放射。亦即，從LED光源11放射的光線40在頂面16及背面19的曲面反射並往前方前進。換言之，照明器具10從框體12的長邊方向(第1方向)觀察而言，在反射部18將來自LED光源11的光線往特定方向反射。並且，照明器具10將在反射部18反射的光線從開口部17放射至外部。藉由如此將從LED光源11放射的光線往特定方向反射，即使從長距離也能視認照明器具10的光線。亦即，想觀賞照明器具10之光線所致裝飾照明的人，即使從長距離也能視認照明器具10的光線。又，航空器或船舶的駕駛員不會直視照明器具10的光線，而能視認照明器具10的光線。 The details of the lighting fixture 10 of the first embodiment will be described below. Fig. 5 is a cross-sectional view showing a line segment A-A of the lighting fixture 10 shown in Fig. 4. As shown in FIG. 5, in the inner side of the frame body 12, the top surface 16 and the back surface 19 are smoothly connected and have a common curved surface, and the common curved surface and the surface perpendicular to the opening surface 171 and the bottom surface 15 of the opening portion 17 are The intersection line is parabolic. That is, the top surface 16 and the back surface 19 have a common curved surface, and the intersection of the common curved surface and the surface of the normal in the longitudinal direction (first direction) is a parabola. The top surface 16 and the back surface 19 are formed with respective curved surfaces such that the focus of the parabola is within the frame 12. Further, as described above, the reflecting portion 18 is provided on the top surface 16 and the back surface 19. The LED light source 11 is intended to be at the focus of the parabola of the top surface 16 and the back surface 19. Since the LED light source 11 emits light radially, the illumination device 10 can emit the light of the LED light source 11 in a fixed direction by providing the LED light source 11 at the focus of the parabola of the top surface 16 and the back surface 19. That is, the light ray 40 radiated from the LED light source 11 is reflected by the curved surfaces of the top surface 16 and the back surface 19, and proceeds forward. In other words, the illuminating device 10 reflects the light from the LED light source 11 in a specific direction in the reflecting portion 18 as viewed in the longitudinal direction (first direction) of the casing 12. Further, the lighting fixture 10 radiates the light reflected by the reflecting portion 18 from the opening portion 17 to the outside. By thus reflecting the light emitted from the LED light source 11 in a specific direction, the light of the lighting fixture 10 can be visually recognized even from a long distance. That is, a person who wants to view the decorative illumination caused by the light of the lighting fixture 10 can visually recognize the light of the lighting fixture 10 even from a long distance. Moreover, the driver of the aircraft or the ship does not look directly at the light of the lighting fixture 10, but can visually recognize the light of the lighting fixture 10.

在實施形態1中，反射部18希望設在框體12的內側面(內面)整面。藉此可將從LED光源11放射的光線有效率地往前方(圖5的箭頭B之方向)反射。 In the first embodiment, the reflection portion 18 is desirably provided on the entire inner surface (inner surface) of the casing 12. Thereby, the light emitted from the LED light source 11 can be efficiently reflected forward (in the direction of the arrow B in FIG. 5).

反射部18亦可設於框體12之內側面(內面)的一部分。亦即，反射部18亦可設於各第1側面13、第2側面14、底面15、頂面16及背面19的至少一部分。例如，可藉由調整在框體12之內側面(內面)設置反射部18的範圍，來調整照明器具10的輝度。 The reflection portion 18 may be provided on a part of the inner side surface (inner surface) of the casing 12. That is, the reflection portion 18 may be provided on at least a part of each of the first side face 13, the second side face 14, the bottom face 15, the top face 16, and the back face 19. For example, the brightness of the lighting fixture 10 can be adjusted by adjusting the range in which the reflecting portion 18 is provided on the inner side surface (inner surface) of the casing 12.

實施形態1中，LED光源11使用高功率且白色的LED元件。如圖3A所示，在框體12的開口部17設有發光色變更面板21以覆蓋開口部17。設於照明器具單元1的3個照明器具10，各設有不同顏色的發光色變更面板21。如圖2所示，於照明器具單元1附近設置有用來使通過橋樑2附近的航空器注意橋樑2之位置的、發光為紅色的航空警示燈8。因此，例如，在照明器具單元1的3個照明器具10設置發光色變更面板21使其分別發光為綠色、藍色、白色。可藉由此種發光色變更面板21來變更照明器具10的發光色，藉而得以簡單地進行顏色變更。又，因為可在全部的LED光源11共通使用白色的LED元件，所以可在將多數之照明器具單元1設置於橋樑2全體時等，更低價地來製造或採購。 In the first embodiment, the LED light source 11 uses a high power and white LED element. As shown in FIG. 3A, a light-emitting color changing panel 21 is provided in the opening 17 of the casing 12 to cover the opening 17. The three lighting fixtures 10 provided in the lighting fixture unit 1 are each provided with an illuminating color changing panel 21 of a different color. As shown in FIG. 2, an aviation warning light 8 that emits red light is provided in the vicinity of the lighting fixture unit 1 so that the aircraft passing through the vicinity of the bridge 2 pays attention to the position of the bridge 2. Therefore, for example, the illuminating color changing panel 21 is provided in the three lighting fixtures 10 of the luminaire unit 1 to emit green, blue, and white, respectively. The illuminating color of the lighting fixture 10 can be changed by the illuminating color changing panel 21, whereby the color can be easily changed. In addition, since the white LED elements can be used in common in all of the LED light sources 11, it is possible to manufacture or purchase them at a lower cost when the plurality of lighting fixture units 1 are installed in the entire bridge 2.

亦即，多數之照明器具10以1對1的方式對應多數顏色，各照明器具10具有：發光色變更面板21，使得從LED光源11放射的光線變更成對應的顏色。 That is, most of the lighting fixtures 10 correspond to a plurality of colors in a one-to-one manner, and each lighting fixture 10 has an illuminating color changing panel 21 that changes the light emitted from the LED light source 11 to a corresponding color.

另，設置於照明器具單元1之3個照明器具10的LED光源11，亦可分別係發出不同顏色的LED元件。例如，可使LED光源11的發色藉由控制點亮部9(圖3A參照)進行調光來實現不同的發色。此時無須發光色變更面板21。 Further, the LED light sources 11 provided in the three lighting fixtures 10 of the lighting fixture unit 1 may also emit LED elements of different colors. For example, the color development of the LED light source 11 can be dimmed by controlling the lighting unit 9 (refer to FIG. 3A) to achieve different color development. In this case, the illuminating color changing panel 21 is not required.

依據上述構成，照明器具單元1可具有不同的發色，使用作為裝飾照明時可提供各種的點亮形式。 According to the above configuration, the lighting fixture unit 1 can have different hair colores, and various lighting forms can be provided when used as decorative lighting.

照明器具單元1設為橋樑之裝飾照明用時，為了防止近距離通過的船舶或航空器之駕駛員直視從照明器具10放射的光線，往垂直方向的發射角受到限制。但是，為了確保從長距離的視認性，尋求擴大發光面。因此照明器具10為了縮窄上下方向(第2方向)的發射角並且擴大發光面，所以藉由加長框體12的左右方向(第1方向)之長度，進而具有對於確保從長距離的視認性而言充足的發光面。 When the lighting fixture unit 1 is used for decorative lighting of a bridge, in order to prevent a driver of a ship or an aircraft passing at a close distance from directly looking at the light emitted from the lighting fixture 10, the emission angle in the vertical direction is restricted. However, in order to ensure visibility from a long distance, it is sought to expand the luminous surface. Therefore, in order to narrow the emission angle in the vertical direction (second direction) and enlarge the light-emitting surface, the illuminating device 10 has the length in the horizontal direction (first direction) of the frame 12, thereby ensuring visibility from a long distance. Ample glowing surface.

圖6A、6B係表示在圖4所示的照明器具10中未設有第1側面13與第2側面14之情況下使照明器具10的左右方向之長度改變時各者之左右方向中的照明器具10之發射角。圖6A係表示左右方向之長度為100cm時的發射角，圖6B係表示左右方向之長度為300cm時的發射角。由圖6A、6B可知，照明器具10的左右方向之長度加長即會擴大往左右方向的發射角。亦即，在將照明器具10的正面方向定為0°時，從±30°到±60°的範圍中，圖6B所示的放射光之範圍會比圖6A所示的放射光之範圍更廣。 6A and 6B show illumination in the left-right direction of each of the lighting fixtures 10 when the first side surface 13 and the second side surface 14 are not provided in the left-right direction when the length of the lighting fixture 10 is changed. The angle of emission of the appliance 10. Fig. 6A shows an emission angle when the length in the left-right direction is 100 cm, and Fig. 6B shows an emission angle when the length in the left-right direction is 300 cm. 6A and 6B, when the length of the luminaire 10 in the left-right direction is lengthened, the emission angle in the left-right direction is enlarged. That is, when the front direction of the lighting fixture 10 is set to 0°, the range of the emitted light shown in FIG. 6B is larger than the range of the emitted light shown in FIG. 6A from the range of ±30° to ±60°. wide.

另一方面，在橋樑2上，照明器具單元1會承受強風，所以其體積宜為盡可能地小(圖1)。因此，希望在確保往期望的左右方向之發射角的同時，也使各構成照明器具單元1的3個照明器具10小型化。 On the other hand, on the bridge 2, the lighting fixture unit 1 is subjected to strong wind, so its volume is preferably as small as possible (Fig. 1). Therefore, it is desirable to reduce the size of the three lighting fixtures 10 constituting the lighting fixture unit 1 while ensuring the emission angle in the desired left-right direction.

實施形態1的照明器具10在框體12的長邊方向設有第1側面13與第2側面14，且在位於框體12內側的面分別設有反射部18。藉由此種構成，框體12的左右方向係相同長度，且可獲得比無第1側面13與第2側面14之情形在左右方向更廣的發射角。圖7係表示實施形態1之照明器具10的左右方向之長度為150cm時往左右方向的發射角。由圖7可知，藉由在框體12設置第1側面13與第2側面14，可在左右方向實現與圖6B所示之框體12的左右方向之長度為300cm且未設有第1側面13與第2側面14之情形相同程度的發射角。亦即，在±30°到±60°的範圍中，圖7所示的放射光之範圍比圖6A所示的放射光之範圍更廣。 In the lighting fixture 10 of the first embodiment, the first side surface 13 and the second side surface 14 are provided in the longitudinal direction of the casing 12, and the reflecting portion 18 is provided on the surface located inside the casing 12. According to this configuration, the frame 12 has the same length in the left-right direction, and an emission angle wider in the left-right direction than in the case where the first side surface 13 and the second side surface 14 are not provided can be obtained. Fig. 7 is a view showing an emission angle in the left-right direction when the length of the lighting fixture 10 of the first embodiment is 150 cm in the left-right direction. As can be seen from Fig. 7, by providing the first side face 13 and the second side face 14 in the casing 12, the length in the left-right direction of the casing 12 shown in Fig. 6B can be 300 cm in the left-right direction and the first side surface is not provided. 13 is the same degree of emission angle as in the case of the second side 14. That is, in the range of ±30° to ±60°, the range of the emitted light shown in Fig. 7 is wider than the range of the emitted light shown in Fig. 6A.

例如，LED光源11僅受到底面15、背面19、及頂面16所圍繞時，從LED光源11放射的光線將有可能往框體12的長邊方向，亦即往圖4所示的箭頭C1、C2的方向洩漏。換言之，從LED光源11放射的光線將會往圖6A所示的大致±90°方向洩漏，將會減少從LED光源11放射的光線之中對於正面方向(大致從-60°起至+60°的範圍)的貢獻。 For example, when the LED light source 11 is only surrounded by the bottom surface 15, the back surface 19, and the top surface 16, the light emitted from the LED light source 11 may be directed to the long side of the frame 12, that is, to the arrow C1 shown in FIG. The direction of C2 leaks. In other words, the light emitted from the LED light source 11 will leak toward the substantially ±90° direction shown in FIG. 6A, which will reduce the front light direction among the light emitted from the LED light source 11 (approximately from -60° to +60°). The scope of the contribution).

其中，在底面15、背面19及頂面16之外，還設置第1側面13與第2側面14時，藉由往例如圖6A所示的大致±90°方向放射的光線進行反射，可增加從LED光源11放射的光線之中對於正面方向(大致從-60°起至+60°的範圍)的貢獻。 In addition, when the first side surface 13 and the second side surface 14 are provided in addition to the bottom surface 15, the back surface 19, and the top surface 16, the light is radiated in a direction of substantially ±90° as shown in FIG. 6A, and can be increased. A contribution from the light emitted from the LED light source 11 to the front direction (a range from approximately -60° to +60°).

如上所述，藉由在照明器具10的框體12之長邊方向設置第1側面13與第2側面14，且在位於框體12內側的面分別設置反射部18，進而得以達成小型化並且確保往左右方向的發射角。 As described above, the first side surface 13 and the second side surface 14 are provided in the longitudinal direction of the casing 12 of the lighting fixture 10, and the reflecting portion 18 is provided on each of the surfaces located inside the casing 12, thereby achieving miniaturization. Make sure that the launch angle is in the left and right direction.

另，在實施形態1中，第1側面13與第2側面14係平面，但不限於平面。例如第1側面13與第2側面14亦可係曲面。 Further, in the first embodiment, the first side surface 13 and the second side surface 14 are flat, but are not limited to a flat surface. For example, the first side surface 13 and the second side surface 14 may be curved surfaces.

(實施形態2) (Embodiment 2)

以下使用圖式說明實施形態2的照明器具。 Hereinafter, the lighting fixture of the second embodiment will be described using the drawings.

圖8係實施形態2的照明器具20之立體圖。照明器具20具有：LED光源11；框體22，收容LED光源11；以及控制點亮部9(圖3A參照)，與LED光源11電性連接並控制點亮LED光源11。框體22具有彼此對向的第1側面(第1面)23及第2側面(第2面)24，並具有底面(第3面)25、頂面(第5面)26、背面(第4面)29。 Fig. 8 is a perspective view of the lighting fixture 20 of the second embodiment. The lighting fixture 20 includes an LED light source 11 , a housing 22 that houses the LED light source 11 , and a lighting unit 9 (see FIG. 3A ) that is electrically connected to the LED light source 11 and controls the LED light source 11 to be lighted. The housing 22 has a first side surface (first surface) 23 and a second side surface (second surface) 24 that face each other, and has a bottom surface (third surface) 25, a top surface (5th surface) 26, and a back surface (the second surface). 4 faces) 29.

底面25將第1側面23與第2側面24加以連結。背面29連接於底面25，並將第1側面23與第2側面24加以連結。頂面26連接於背面29，並將第1側面23與第2側面24加以連結。底面25與頂面26分別將第1側 面23與第2側面24加以連結。框體22具有開口部27，開口部27受到第1側面23、第2側面24、底面25及頂面26所圍。框體22形成為以第1側面23與第2側面24所對向的方向為長邊方向(第1方向)。底面25形成平面，LED光源11係設於底面25。底面25形成為在框體22之長邊方向上細長的矩形形狀，將第1側面23與第2側面24在長邊方向加以連結。 The bottom surface 25 connects the first side surface 23 and the second side surface 24 . The back surface 29 is connected to the bottom surface 25, and the first side surface 23 and the second side surface 24 are coupled to each other. The top surface 26 is connected to the back surface 29, and the first side surface 23 and the second side surface 24 are coupled to each other. The bottom surface 25 and the top surface 26 respectively have the first side The surface 23 is joined to the second side surface 24. The casing 22 has an opening 27, and the opening 27 is surrounded by the first side face 23, the second side face 24, the bottom face 25, and the top face 26. The frame 22 is formed such that the direction in which the first side surface 23 and the second side surface 24 face each other is the longitudinal direction (first direction). The bottom surface 25 is formed in a plane, and the LED light source 11 is provided on the bottom surface 25. The bottom surface 25 is formed in a rectangular shape elongated in the longitudinal direction of the casing 22, and the first side surface 23 and the second side surface 24 are coupled in the longitudinal direction.

在框體22的內側，背面29具有曲面，該曲面所與垂直於開口部27之開口面271及底面25的面之交線係拋物線。亦即，背面29具有共通的曲面，該共通的曲面所與法線在長邊方向(第1方向)上的面之交線係拋物線。頂面26係設為與底面25平行。 On the inner side of the casing 22, the back surface 29 has a curved surface which is parabolic to the intersection of the surface perpendicular to the opening surface 271 and the bottom surface 25 of the opening 27. That is, the back surface 29 has a common curved surface, and the intersection of the common curved surface and the surface of the normal in the longitudinal direction (first direction) is a parabola. The top surface 26 is set to be parallel to the bottom surface 25.

與實施形態1的照明器具10同樣地，照明器具20亦可用於實施形態1的照明器具單元1。又，與實施形態1的照明器具10同樣地，在將白色的發光元件用於照明器具20之LED光源11時，如圖3A所示，可藉由將發光色變更面板21設於開口部27，來變更照明器具20的發光色。又，將RGB之發光元件使用於照明器具20之LED光源11時，可藉由與各LED光源11電性連接的控制點亮部9進行調光，來變更發光色。 Similarly to the lighting fixture 10 of the first embodiment, the lighting fixture 20 can also be used in the lighting fixture unit 1 of the first embodiment. Further, similarly to the lighting fixture 10 of the first embodiment, when the white light-emitting element is used for the LED light source 11 of the lighting fixture 20, the luminescent color changing panel 21 can be provided in the opening 27 as shown in FIG. 3A. The illuminating color of the lighting fixture 20 is changed. Further, when the RGB light-emitting elements are used for the LED light source 11 of the luminaire 20, the illuminating color can be changed by dimming the control lighting unit 9 electrically connected to each of the LED light sources 11.

又，將實施形態1所述的構成應用於實施形態2的照明器具20亦獲得同樣的效果。在實施形態2的照明器具20中，希望將LED光源11設置於背面29與垂直於開口部27的開口面271及底面25的面之交線即拋物線的焦點。藉此，照明器具20可更有效率地往前方方向照射LED光源11之光線。 Further, the same effects can be obtained by applying the configuration described in the first embodiment to the lighting fixture 20 of the second embodiment. In the luminaire 20 of the second embodiment, it is desirable to provide the LED light source 11 at the focal point of the parabola which is the intersection of the back surface 29 and the surface perpendicular to the opening surface 271 and the bottom surface 25 of the opening 27. Thereby, the lighting fixture 20 can more efficiently illuminate the light of the LED light source 11 in the forward direction.

以下說明實施形態2的照明器具20之特徵。如圖2所示，尋求一種構成，在將照明器具單元1用於橋樑2時，照明器具20往水平方向放射光線，且通過附近的船舶或航空器之駕駛員不直視光源。為使實施形態2的照明器具20更難從外直視光源，具有與底面25平行的頂面26。藉由在照明器具20設置頂面26，可防止例如通過光源附近的人從上方直視LED光源11。 The features of the lighting fixture 20 of the second embodiment will be described below. As shown in Fig. 2, a configuration is sought in which, when the lighting fixture unit 1 is used for the bridge 2, the lighting fixture 20 emits light in a horizontal direction, and the driver of the nearby ship or aircraft does not look directly at the light source. In order to make it easier for the luminaire 20 of the second embodiment to look directly at the light source from the outside, the top surface 26 parallel to the bottom surface 25 is provided. By providing the top surface 26 in the lighting fixture 20, it is possible to prevent the LED light source 11 from being viewed directly from above, for example, by a person in the vicinity of the light source.

如圖8所示，第1側面23、第2側面24、底面25及背面29分別設有反射部28。在實施形態2中，反射部28希望設在各第1側面23、第2側面24、底面25及背面29的整面。藉此，能更有效率地將從LED光源11發光的光線往前方放射。 As shown in FIG. 8, the first side surface 23, the second side surface 24, the bottom surface 25, and the back surface 29 are provided with reflection portions 28, respectively. In the second embodiment, the reflection portion 28 is desirably provided on the entire surfaces of the first side face 23, the second side face 24, the bottom face 25, and the back face 29. Thereby, the light emitted from the LED light source 11 can be radiated more efficiently forward.

另一方面，頂面26設有反射光降低部30。因為頂面26係設為與底面25平行，所以假設於頂面26設有反射部，在頂面26反射的光線不僅往前方反射，還往比前方更下方反射。如上所述，在用於橋樑的照明器具中，因為往垂直方向的發射角受到限制，所以可期望降低往下方的反射。因此，在實施形態2的照明器具20中，可藉由在頂面26設置反射光降低部30，來防止光線從頂面26側往下方反射。 On the other hand, the top surface 26 is provided with a reflected light reducing portion 30. Since the top surface 26 is formed to be parallel to the bottom surface 25, it is assumed that the top surface 26 is provided with a reflection portion, and the light reflected on the top surface 26 is reflected not only forward but also downward from the front. As described above, in the lighting fixture for a bridge, since the emission angle to the vertical direction is restricted, it is desirable to reduce the reflection downward. Therefore, in the luminaire 20 of the second embodiment, the reflected light reducing portion 30 can be provided on the top surface 26 to prevent the light from being reflected downward from the top surface 26 side.

反射光降低部30，例如，粗糙地形成在位於框體22內側的頂面26，可使入射的光線漫射藉以降低往單方向的反射。又，若在位於框體22內側的頂面26塗布黑色塗料等光吸收材料來作為反射光降低部30，可降低從頂面26側往下方的光線之反射。可藉由如此在框體22內側設置具有反射光降低部30的頂面26，防止從上方的直視並且降低往下方的反射。 The reflected light reducing portion 30 is, for example, roughly formed on the top surface 26 located inside the frame 22, and can diffuse incident light to reduce reflection in one direction. Further, when a light absorbing material such as a black paint is applied to the top surface 26 located inside the casing 22 as the reflected light reducing portion 30, reflection of light rays from the side of the top surface 26 downward can be reduced. By thus providing the top surface 26 having the reflected light reducing portion 30 inside the casing 22, the direct view from above can be prevented and the downward reflection can be reduced.

圖9A、9B係表示實施形態2之照明器具20的發射角，圖9A係表示照明器具20之左右方向中的發射角，圖9B係表示照明器具20之上下方向中的發射角。另，在實施形態2中，照明器具20之左右方向係框體22之長邊方向(第1方向)，照明器具單元1設置成照明器具20之左右方向係水平方向。又，照明器具20之上下方向係底面25之法線方向(第2方向)，照明器具單元1設置成照明器具20之上下方向係垂直方向。由圖9A、9B亦可知，相較於左右方向的發射角而言，上下方向的發射角大幅受到限制。 9A and 9B show the emission angle of the lighting fixture 20 of the second embodiment, Fig. 9A shows the emission angle in the left-right direction of the lighting fixture 20, and Fig. 9B shows the emission angle in the upper and lower directions of the lighting fixture 20. In the second embodiment, the left and right direction of the luminaire 20 is in the longitudinal direction (first direction) of the casing 22, and the luminaire unit 1 is disposed such that the left and right directions of the luminaire 20 are horizontal. Further, in the normal direction of the lighting fixture 20 in the normal direction of the bottom surface 25 (second direction), the luminaire unit 1 is disposed such that the illuminating device 20 is vertically oriented in the vertical direction. 9A and 9B, the emission angle in the vertical direction is greatly limited as compared with the emission angle in the left-right direction.

如上所述，實施形態2的照明器具20藉由設為與底面25平行，且具有形成反射光降低部30的頂面26，藉而得以縮小往上下方向的發射角並且防止從上方的直視。 As described above, the lighting fixture 20 of the second embodiment has a top surface 26 that forms the reflected light reducing portion 30 in parallel with the bottom surface 25, thereby reducing the emission angle in the vertical direction and preventing direct viewing from above.

另，上述各實施形態中，設於照明器具10、20的LED光源11分別為1個發光元件，但不限於此。亦可使用多數之發光元件來構成LED光源11。又，上述各實施形態中，LED光源11係設於底面15或底面25，但不限於此構成。例如亦可在底面15或底面25藉由用來設置LED光源11的設置台來設置LED光源11。在此種情況下，也宜使LED光源11位於拋物線之焦點，該拋物線係背面19及頂面16具有的曲面所與垂直於開口部17之開口面171及底面15的面之交線。LED光源11宜位於拋物線之焦點，該拋物線係背面29具有的曲面所與垂直於開口部27之開口面271及底面25的面之交線。 Further, in each of the above embodiments, the LED light sources 11 provided in the lighting fixtures 10 and 20 are each one of the light-emitting elements, but the invention is not limited thereto. The LED light source 11 can also be constructed using a plurality of light-emitting elements. Further, in the above embodiments, the LED light source 11 is provided on the bottom surface 15 or the bottom surface 25, but the configuration is not limited thereto. For example, the LED light source 11 can also be provided on the bottom surface 15 or the bottom surface 25 by means of a setting table for arranging the LED light source 11. In this case, it is also preferable that the LED light source 11 is located at the focal point of the parabola, and the curved surface of the back surface 19 and the top surface 16 has a line intersecting the surface perpendicular to the opening surface 171 and the bottom surface 15 of the opening 17. The LED light source 11 is preferably located at the focus of the parabola, and the parabola back surface 29 has a curved surface intersecting the surface perpendicular to the opening surface 271 and the bottom surface 25 of the opening 27.

又，上述各實施形態中，上下方向(第2方向)與左右方向(第1方向)係指照明器具單元1及照明器具10、20中的相對方向，水平方向與垂直方向係指絶對方向。 Further, in each of the above embodiments, the vertical direction (second direction) and the left-right direction (first direction) refer to the opposing directions in the luminaire unit 1 and the luminaires 10 and 20, and the horizontal direction and the vertical direction refer to the absolute direction.

另，各實施形態係說明配置成照明器具10、20以第1面為第1側面、第2面為第2側面，設置有LED光源11的第3面為底面、第4面為背面、第5面為頂面之情形，但照明器具10、20的配置不限於此。例如，照明器具10、20亦可配置成以設有LED光源11的第3面為頂面、第5面為底面。 In the respective embodiments, the lighting fixtures 10 and 20 are arranged such that the first surface is the first side surface and the second surface is the second side surface, and the third surface on which the LED light source 11 is provided is the bottom surface, and the fourth surface is the back surface. The fifth surface is the top surface, but the arrangement of the lighting fixtures 10, 20 is not limited thereto. For example, the lighting fixtures 10 and 20 may be arranged such that the third surface on which the LED light source 11 is provided is the top surface and the fifth surface is the bottom surface.
