另外，LED既可將LED晶片直接安裝於基板21，而且，也可安裝炮彈型的LED，安裝方式或形式並無特別限定。 Further, the LED can mount the LED chip directly on the substrate 21, and a bullet-type LED can also be mounted. The mounting method or form is not particularly limited.
以此方式構成的光源部2如圖4及圖6代表性地所示，基板21位於本體1的前表面側且開口11周圍，換言之，位於後述的安裝部5的周圍，發光元件22的安裝面朝向前表面側，即朝向下方的照射方向而配設。而且，以基板21的背面側緊貼於本體1的內面側的方式，通過例如螺絲等的固定機構而安裝。因此，基板21是與本體1熱結合，來自基板21的熱從背面側傳導至本體1並得以散發。 As shown in FIGS. 4 and 6 , the light source unit 2 configured in this manner is located on the front surface side of the main body 1 and around the opening 11 , in other words, around the mounting portion 5 to be described later, and the mounting of the light-emitting element 22 . The surface is disposed toward the front surface side, that is, toward the downward irradiation direction. Moreover, the back surface side of the substrate 21 is attached to the inner surface side of the main body 1 by a fixing mechanism such as a screw. Therefore, the substrate 21 is thermally coupled to the body 1, and heat from the substrate 21 is conducted from the back side to the body 1 and is radiated.
另外，基板21既可為直接安裝於本體1而配設的情況，也可經由其他構件而間接地安裝而配設的情況，其配設形態並無特別限定。 Further, the substrate 21 may be disposed directly to the main body 1 or may be indirectly attached via another member, and the arrangement form thereof is not particularly limited.
如圖2及圖6所示，在光源部2的前表面側配設著光源部罩25。光源部罩25例如包含聚碳酸酯(polycarbonate)或丙烯酸樹脂(acryl resin)等的具有絕緣性的透明合成樹脂，且沿著所述發光元件22的配置而呈大致圓環狀地一體形成，並以將發光元件22包括在內而覆蓋基板21的整個 面的方式而配設。 As shown in FIGS. 2 and 6, a light source unit cover 25 is disposed on the front surface side of the light source unit 2.

因此，從發光元件22出射的光將透過光源部罩25。而且，由於覆蓋基板21的整個面，因此充電部被光源部罩25覆蓋而絕緣性得以確保。進而，光源部罩25是與本體1接觸並通過螺固而安裝，因此來自本體1的熱得以傳導並散發。 Therefore, the light emitted from the light-emitting element 22 is transmitted through the light source unit cover 25. Moreover, since the entire surface of the substrate 21 is covered, the charging portion is covered by the light source unit cover 25, and insulation is ensured. Further, the light source unit cover 25 is in contact with the body 1 and is attached by screwing, so that heat from the body 1 is conducted and emitted.

The circuit board 31 is formed in a substantially rectangular shape by a glass epoxy resin (FR-4) or the like, and a notch portion 31a is formed in the center portion. The notch portion 31a has a circular shape and is formed by continuously cutting a part thereof so as to protrude outward. The notch portion 31a is a portion into which the mounting portion 5 to be described later is inserted.
因此，電路基板31以包圍中央部的周圍的方式而形成為板狀，在其表面側安裝著電路零件32。具體而言，在電路基板31上，在切口部31a的周圍安裝著對發光元件22進行點燈控制所需的電路零件32，例如安裝著控制用積體電路(Integrated Circuit，IC)、電阻元件、變壓器(transformer)、開關電晶體(switching transistor)、恒電壓二極體、全波整流器、電容器(condenser)等。 Therefore, the circuit board 31 is formed in a plate shape so as to surround the periphery of the center portion, and the circuit component 32 is attached to the front surface side. Specifically, on the circuit board 31, a circuit component 32 necessary for lighting control of the light-emitting element 22 is mounted around the notch portion 31a, and for example, a control integrated circuit (IC) and a resistance element are mounted. , transformers, switching transistors, constant voltage diodes, full-wave rectifiers, capacitors, etc.
而且，在切口部31a的附近，主要安裝著電路零件32中的控制用IC、電阻元件或變壓器等的發熱量相對較大的發熱零件32H，在外周側安裝著發熱量相對較小的電路零件。 In the vicinity of the notch portion 31a, a heat generating component 32H having a relatively large amount of heat generation such as a control IC, a resistor element, or a transformer in the circuit component 32 is mounted, and a circuit component having a relatively small heat generation amount is attached to the outer peripheral side. .
在電路基板32上，電性連接著適配器A側，並經由 適配器A而連接于商用交流電源。因此，點燈裝置3接收該交流電源而生成直流輸出，並經由導線而將該直流輸出供給至發光元件22，以對發光元件22進行點燈控制。 On the circuit board 32, electrically connected to the adapter A side, and via Adapter A is connected to a commercial AC power source. Therefore, the lighting device 3 receives the AC power supply to generate a DC output, and supplies the DC output to the light-emitting element 22 via a wire to perform lighting control of the light-emitting element 22.
此種點燈裝置3安裝於點燈裝置罩35而受到覆蓋，從而配置於本體1的背面側。此時，電路基板31將電路零件32朝向前表面側(圖示上、下方側)而安裝。 Such a lighting device 3 is attached to the lighting device cover 35 and covered, and is disposed on the back side of the main body 1. At this time, the circuit board 31 mounts the circuit component 32 toward the front surface side (upper and lower sides in the drawing).
點燈裝置罩35是由冷軋鋼板等的金屬材料而形成大致四邊形的短筒狀，側壁35a以朝向前表面側擴開的方式而呈傾斜狀，在背面壁35b的中央部形成有開口35c。 The lighting device cover 35 is formed in a short rectangular shape having a substantially rectangular shape by a metal material such as a cold-rolled steel plate, and the side wall 35a is inclined so as to expand toward the front surface side, and an opening 35c is formed in a central portion of the rear surface 35b. .
該點燈裝置罩35如圖3、圖5及圖6所示，前表面側的凸緣(flange)被載置於本體1即底架的突出部12，並且被螺固，從而熱結合地予以安裝。 As shown in FIG. 3, FIG. 5, and FIG. 6, the lighting device cover 35 is placed on the front surface side flanges of the main body 1, that is, the projections 12 of the chassis, and is screwed to be thermally coupled. Install it.
中心構件4如圖2、圖4及圖6所示，是由聚對苯二甲酸丁二醇酯(polybutylene terephthalate，PBT)樹脂等的合成樹脂材料所製作並形成為大致短圓筒狀，且在中央部具有與吸頂燈座主體Cb相向的開口41。而且，在開口41的周圍，形成有環狀的空間部42，在該空間部42內配設後述的光感測器6。進而，在中心構件4的前表面壁上，形成有與光感測器6的受光部相向的受光窗43。 As shown in FIGS. 2, 4, and 6, the center member 4 is made of a synthetic resin material such as polybutylene terephthalate (PBT) resin and is formed into a substantially short cylindrical shape. The central portion has an opening 41 facing the ceiling holder main body Cb. Further, an annular space portion 42 is formed around the opening 41, and a photosensor 6 to be described later is disposed in the space portion 42. Further, a light receiving window 43 facing the light receiving portion of the photo sensor 6 is formed on the front surface wall of the center member 4.
以此方式構成的中心構件4主要如圖6所示，背面側的凸緣經由光源部罩25螺固於底架而安裝。另外，中心構件4可直接或間接地安裝於底架，其具體的安裝結構並無限定。 The center member 4 configured in this manner is mainly attached as shown in FIG. 6, and the flange on the back side is screwed to the chassis via the light source unit cover 25. In addition, the center member 4 may be directly or indirectly mounted to the chassis, and the specific mounting structure thereof is not limited.
安裝部5為適配器引導部(adapter guide)，是適配 器A所插通並卡合的構件，是用於將照明器具安裝於天花板面C的構件。適配器引導部如圖3及圖6所示，形成為大致圓筒狀，在中央部設有適配器A所插通並卡合的卡合口51。該適配器引導部是對應於本體1的中央部所形成的開口11而配設。 The mounting portion 5 is an adapter guide that is adapted The member that is inserted and engaged by the device A is a member for attaching the lighting fixture to the ceiling surface C. As shown in FIGS. 3 and 6, the adapter guide portion is formed in a substantially cylindrical shape, and an engagement opening 51 through which the adapter A is inserted and engaged is provided at the center portion. The adapter guide portion is disposed corresponding to the opening 11 formed in the central portion of the body 1.
另外，安裝部5未必是被稱作適配器引導部等的構件。例如，也可以使形成在本體1等上的開口，主要是指與作為配線器具的吸頂燈座主體Cb相向且使適配器A卡合的構件或部分。 Further, the mounting portion 5 is not necessarily a member called an adapter guiding portion or the like. For example, the opening formed in the main body 1 or the like may mainly be a member or a portion that faces the ceiling holder main body Cb as a wiring device and engages the adapter A.
光感測器6如圖6所示為照度感測器，包含光電二極體(photo diode)等的感測器元件，以對周圍的亮度進行偵測並輸出檢測信號的方式進行動作。借此，當周圍明亮時，以對光源部2即發光元件22進行調光(減光)而點燈的方式來進行控制。 As shown in FIG. 6, the photo sensor 6 includes an illuminance sensor, and includes a sensor element such as a photo diode, and operates to detect the surrounding brightness and output a detection signal. Thereby, when the surroundings are bright, the light source unit 2, that is, the light-emitting element 22, is dimmed (dimmed) and turned on.
光感測器6被安裝在基板上，以其受光部與受光窗43相向的方式而配設並安裝在中心構件4的空間部42內。 The photo sensor 6 is mounted on a substrate, and is disposed so as to face the light receiving portion 43 so as to face the light receiving window 43 and be attached to the space portion 42 of the center member 4.
燈罩7是由丙烯酸樹脂等的具有透光性且呈乳白色並具備擴散性的材料而形成為大致圓形狀，且在中央部形成有圓形狀的開口71。而且，在燈罩7的外周部安裝著燈罩裝飾框7a，該燈罩裝飾框7a由包含丙烯酸樹脂等的透明材料所形成。 The shade 7 is formed into a substantially circular shape by a light-transmissive material having a light-transmissive property such as an acrylic resin and having diffusibility, and a circular opening 71 is formed in the center portion. Further, a shade decorative frame 7a is formed on the outer peripheral portion of the globe 7, and the shade decorative frame 7a is formed of a transparent material containing acrylic resin or the like.
並且，燈罩7以覆蓋包括光源部2在內的本體1的前表面側的方式，可裝卸地安裝於本體1的外周緣部。具體而言，通過轉動燈罩7，將燈罩7上所設的燈罩安裝卡扣 74卡合於燈罩受卡扣75而安裝，所述燈罩受卡扣75設在由本體1的突出部14所形成的凹部內。 Further, the shade 7 is detachably attached to the outer peripheral edge portion of the main body 1 so as to cover the front surface side of the main body 1 including the light source unit 2. Specifically, by rotating the lamp cover 7, the lamp cover provided on the lamp cover 7 is buckled. The snap-in 74 is attached to the cover by a snap 75 which is provided in the recess formed by the projection 14 of the body 1.
而且，在拆卸燈罩7時，朝向與安裝時相反的方向轉動燈罩7，以解除燈罩安裝卡扣74與燈罩受卡扣75的卡合，從而可拆卸所述燈罩7。 Further, when the lamp cover 7 is removed, the lamp cover 7 is rotated in a direction opposite to the mounting time to release the engagement between the lamp cover mounting buckle 74 and the lamp cover receiving buckle 75, so that the lamp cover 7 can be detached.
另外，燈罩7優選採用可裝卸地安裝於本體1的外周緣部的結構，但也可採用通過螺絲等的固定機構而固定於本體1的結構。這是因為，對於使用發光元件22來作為光源以可期待長壽命化的照明器具而言，為了維護(maintenance)而更換光源，或者清掃內部的必要性少。 Further, the shade 7 is preferably detachably attached to the outer peripheral edge portion of the main body 1. However, the cover 7 may be fixed to the main body 1 by a fixing mechanism such as a screw. This is because, in the lighting fixture that uses the light-emitting element 22 as a light source and can be expected to have a long life, it is necessary to replace the light source for maintenance or to clean the inside.
而且，所述光源部罩25與燈罩7之間的距離被設定為20 mm~60 mm，優選被設定為30 mm~50 mm。借此，照射光的均勻度變得良好，從本體1傳導至光源部罩25的熱經由燈罩7而有效地散發。 Further, the distance between the light source unit cover 25 and the lamp cover 7 is set to 20 mm to 60 mm, preferably set to 30 mm to 50 mm. Thereby, the uniformity of the irradiation light becomes good, and the heat conducted from the main body 1 to the light source unit cover 25 is efficiently dissipated via the globe 7.
進而，也可在燈罩7的內面側貼附具有導熱性的聚烯烴片材(polyolefine sheet)等。此時，能夠提高從燈罩7散熱性。 Further, a polyolefin sheet or the like having thermal conductivity may be attached to the inner surface side of the globe 7. At this time, heat dissipation from the globe 7 can be improved.
罩構件8如圖2及圖6所示，由透明的丙烯酸樹脂等的材料而形成為圓形狀。該罩構件8對應於燈罩7的開口71而安裝於中心構件4的前表面壁，且以覆蓋並堵塞中心構件4的開口41的方式而配設。而且，在罩構件8上，形成有與光感測器6的受光窗43相向的圓形狀的透過部81。 As shown in FIGS. 2 and 6, the cover member 8 is formed into a circular shape from a material such as a transparent acrylic resin. The cover member 8 is attached to the front surface wall of the center member 4 corresponding to the opening 71 of the globe 7, and is disposed to cover and close the opening 41 of the center member 4. Further, a circular transmissive portion 81 that faces the light receiving window 43 of the photosensor 6 is formed on the cover member 8.
另外，較為理想的是，在罩構件8的前表面側，至少保留透過部81而貼附不透光性的薄膜材等。 Further, it is preferable that at least the transmissive portion 81 is left on the front surface side of the cover member 8 to attach a opaque film material or the like.
間接光光源部9配設在本體1的背面側，主要具有照亮天花板面的功能。如圖3、圖5及圖6所示，間接光光源部9位於安裝部5的周圍而配設有多個，且具備基板91以及安裝於該基板91上的多個發光元件92。 The indirect light source unit 9 is disposed on the back side of the main body 1 and mainly has a function of illuminating the ceiling surface. As shown in FIGS. 3, 5, and 6, the indirect light source unit 9 is disposed around the mounting portion 5 and is provided with a plurality of substrates 91 and a plurality of light-emitting elements 92 mounted on the substrate 91.
基板91形成為大致長方形狀的平板，發光元件92是沿著該基板91的長邊方向而排列並安裝成直線狀。 The substrate 91 is formed into a substantially rectangular flat plate, and the light-emitting elements 92 are arranged in a line shape along the longitudinal direction of the substrate 91.
安裝有該發光元件92的基板91被安裝在所述點燈裝置罩35的側壁35a上的四處部位。此時，點燈裝置罩35形成為大致四邊形，基板91被安裝在該側壁35a上的直線狀的平坦面上，因此可穩定地進行安裝。 The substrate 91 on which the light-emitting element 92 is mounted is attached to four places on the side wall 35a of the lighting device cover 35. At this time, the lighting device cover 35 is formed in a substantially quadrangular shape, and the substrate 91 is attached to the linear flat surface on the side wall 35a, so that the mounting can be stably performed.
而且，構成基板91的安裝部的側壁35a是形成為朝向前表面側而擴開的傾斜狀，因此基板91朝向斜上方即天花板面方向，從發光元件92出射的光朝向天花板面方向而有效地進行照射。 Further, since the side wall 35a of the mounting portion constituting the substrate 91 is formed in an inclined shape that is expanded toward the front surface side, the substrate 91 is directed obliquely upward, that is, in the ceiling surface direction, and the light emitted from the light-emitting element 92 is directed toward the ceiling surface direction. Irradiation is performed.
進而，各間接光光源部9由箱狀的透光性的罩93所覆蓋。 Further, each of the indirect light source units 9 is covered by a box-shaped translucent cover 93.
發光元件92是與所述光源部2同樣地為LED，為表面安裝型的LED封裝。並且，發光元件92連接於點燈裝置3而受到點燈控制。 The light-emitting element 92 is an LED package similar to the light source unit 2 and is a surface mount type LED package. Further, the light-emitting element 92 is connected to the lighting device 3 and is controlled by lighting.
彈性構件10對應於所述多個各間接光光源部9的安裝位置而安裝於其附近。彈性構件10是在照明器具被安裝于作為器具安裝面的天花板面C上的狀態下，以介隔(stand between)在與天花板面C之間的方式而配設的構件(參照圖8)。 The elastic member 10 is attached to the vicinity of the installation position of the plurality of indirect light source units 9. The elastic member 10 is a member that is disposed between the ceiling surface C and the ceiling surface C in a state where the lighting fixture is attached to the ceiling surface C as the appliance mounting surface (see FIG. 8 ).
具體而言，彈性構件10是包含不銹鋼等材料的金屬制的彈簧構件，且對應於各間接光光源部9的安裝位置而安裝於點燈裝置罩35的背面側。彈性構件10是將橫長的長方形狀的板簧彎曲而形成，在中央部具有固定部10a，從該固定部10a的兩側以朝向斜上方(背面側)擴開的方式而形成有延伸部10b，在其前端側，形成有呈四邊形狀的抵接部10c。 Specifically, the elastic member 10 is a metal spring member including a material such as stainless steel, and is attached to the back side of the lighting device cover 35 in accordance with the attachment position of each indirect light source unit 9 . The elastic member 10 is formed by bending a horizontally long rectangular leaf spring, and has a fixing portion 10a at a central portion thereof, and an extending portion is formed to extend obliquely upward (back side) from both sides of the fixing portion 10a. 10b, on the front end side thereof, a contact portion 10c having a quadrangular shape is formed.
而且，在固定部10a上，形成有螺絲貫通孔，通過貫通該螺絲貫通孔並螺入點燈裝置罩35的背面側的安裝螺絲，彈性構件10被固定於點燈裝置罩35的背面側。 Further, a screw through hole is formed in the fixing portion 10a, and the elastic member 10 is fixed to the back side of the lighting device cover 35 by a mounting screw that penetrates the screw through hole and is screwed into the back side of the lighting device cover 35.
多個即4個此種彈性構件10均使用相同形態且具有相同的彈性力者。 A plurality of, that is, four such elastic members 10 all use the same form and have the same elastic force.
在彈性構件10的固定狀態下，如圖6代表性地所示，配設在點燈裝置罩35背面側的彈性構件10能以固定部10a為支點，伴隨彈簧作用而朝前表面側方向(圖示箭頭方向)彈性變形。 In the fixed state of the elastic member 10, as schematically shown in Fig. 6, the elastic member 10 disposed on the back side of the lighting device cover 35 can be supported by the fixing portion 10a toward the front surface side side with the action of the spring ( The direction of the arrow is shown to be elastically deformed.
適配器A如圖8所示，是通過設在上表面側的掛鈎而電性且機械地連接於設置在天花板面C上的吊頂燈座主體Cb的部分，呈大致圓筒狀，且在周壁的兩側，以通過內置的彈簧(spring)而始終向外周側突出的方式而設有一對卡止部A1。該卡止部A1通過對設在下表面側的操作杆(lever)進行操作而沒入。而且，從該適配器A導出有連接至所述點燈裝置3的未圖示的電源線(cord)，並經由連接器而與點燈裝置3連接。 As shown in Fig. 8, the adapter A is electrically and mechanically connected to a portion of the ceiling holder main body Cb provided on the ceiling surface C by a hook provided on the upper surface side, and has a substantially cylindrical shape and a peripheral wall. A pair of locking portions A1 are provided on both sides so as to always protrude toward the outer peripheral side by a built-in spring. The locking portion A1 is immersed by operating the lever provided on the lower surface side. Further, a cord (not shown) connected to the lighting device 3 is led out from the adapter A, and is connected to the lighting device 3 via a connector.
在以此方式構成的照明器具中，參照圖4、圖6及圖7來說明光源部2與點燈裝置3的配置關係。另外，圖7是平面性地表示光源部2與點燈裝置3的位置關係的說明圖。 In the lighting fixture configured in this manner, the arrangement relationship between the light source unit 2 and the lighting device 3 will be described with reference to FIGS. 4, 6, and 7. In addition, FIG. 7 is an explanatory view showing the positional relationship between the light source unit 2 and the lighting device 3 in a planar manner.
光源部2是在大致圓環狀的基板21的周上安裝多個發光元件22而構成。並且，該基板21是將背面側熱結合於本體1而安裝。因此，所述多個發光元件22配設在安裝部5的周圍，具體而言，主要如圖4及圖7所示，俯視時以圍繞安裝部5周圍的方式而配設。 The light source unit 2 is configured by mounting a plurality of light-emitting elements 22 on the circumference of a substantially annular substrate 21 . Further, the substrate 21 is attached by thermally bonding the back side to the body 1. Therefore, the plurality of light-emitting elements 22 are disposed around the mounting portion 5, and specifically, as shown in FIGS. 4 and 7, are disposed so as to surround the periphery of the mounting portion 5 in plan view.
另一方面，點燈裝置3如圖6所示，配設在本體1的背面側，且朝背面方向與光源部2空開隔離距離d而安裝於點燈裝置罩35。進而，電路零件32以圍繞安裝部5周圍的方式而配設，並且如圖7所示，位於排列在周上的多個發光元件22的內側，所述安裝部5插通電路基板31的切口部31a。 On the other hand, as shown in FIG. 6, the lighting device 3 is disposed on the back side of the main body 1, and is attached to the lighting device cover 35 at an isolation distance d from the light source unit 2 in the back surface direction. Further, the circuit component 32 is disposed so as to surround the periphery of the mounting portion 5, and as shown in FIG. 7, is located inside the plurality of light-emitting elements 22 arranged on the circumference, and the mounting portion 5 is inserted through the slit of the circuit substrate 31. Part 31a.
而且，在安裝部5的附近，配置電路零件32中的發熱量相對較大的發熱零件32H。 Further, in the vicinity of the mounting portion 5, the heat generating component 32H having a relatively large amount of heat generation in the circuit component 32 is disposed.
因此，光源部2中的發光元件22與點燈裝置3中的電路零件32朝背面方向空開隔離距離d而配置，而且，電路零件32位於發光元件22的內側。即，發光元件22與電路零件32在垂直方向(前背方向)及水準方向(半徑方向)這兩個方向上，均錯開而配置。而且，電路零件32中的發熱零件32H遠離發光元件22而配置。 Therefore, the light-emitting element 22 in the light source unit 2 and the circuit component 32 in the lighting device 3 are disposed at an isolation distance d in the back surface direction, and the circuit component 32 is located inside the light-emitting element 22. In other words, the light-emitting element 22 and the circuit component 32 are arranged in a staggered manner in both the vertical direction (front-back direction) and the horizontal direction (radial direction). Further, the heat generating component 32H in the circuit component 32 is disposed away from the light emitting element 22.
因此，發光元件22與電路零件32採用熱分離的配 置，從而能夠抑制從發光元件22與電路零件32產生的熱的相互的熱干涉。 Therefore, the light-emitting element 22 and the circuit component 32 are thermally separated. This makes it possible to suppress mutual thermal interference of heat generated from the light-emitting element 22 and the circuit component 32.
而且，發光元件22及電路零件32配設在以安裝部5為中心的周圍，因此能夠緊湊(compact)地構成。進而，點燈裝置3配設在本體1的背面側，因此不會縮窄從光源部2出射的光的範圍，而能夠確保規定的配光範圍。 Further, since the light-emitting element 22 and the circuit component 32 are disposed around the mounting portion 5, they can be configured in a compact manner. Further, since the lighting device 3 is disposed on the back side of the main body 1, the range of light emitted from the light source unit 2 is not narrowed, and a predetermined light distribution range can be secured.
接下來，參照圖8來說明照明器具安裝於天花板面C的安裝狀態。首先，將適配器A電性且機械地連接於預先設置在天花板面C上的吸頂燈座主體Cb。在拆卸照明器具的罩構件8的狀態下，一方面使適配器引導部的卡合口51對準適配器A，一方面克服彈性構件10的彈性力而從下方用手上推器具本體1，直至適配器A的卡止部A1確實地卡合於適配器引導部的卡合口51為止，從而進行安裝操作。 Next, an installation state in which the lighting fixture is attached to the ceiling surface C will be described with reference to Fig. 8 . First, the adapter A is electrically and mechanically connected to the ceiling holder main body Cb previously provided on the ceiling surface C. In the state in which the cover member 8 of the lighting fixture is disassembled, on the one hand, the engaging opening 51 of the adapter guiding portion is aligned with the adapter A, and on the other hand, against the elastic force of the elastic member 10, the appliance body 1 is pushed up by hand from below until the adapter A The locking portion A1 is surely engaged with the engagement opening 51 of the adapter guide portion to perform the mounting operation.
接下來，安裝罩構件8，以覆蓋並堵塞與吸頂燈座主體Cb相向的中心構件4的中央部的開口41。 Next, the cover member 8 is attached to cover and close the opening 41 of the central portion of the center member 4 facing the ceiling holder main body Cb.
在此狀態下，彈性構件10發生彈性變形，抵接部10c彈性地抵接於天花板面C。並且，抵接部10c可在大致平面上平行地，或者以前端部稍許朝向鉛垂方向的方式抵接於天花板面C。 In this state, the elastic member 10 is elastically deformed, and the abutting portion 10c elastically abuts against the ceiling surface C. Further, the abutting portion 10c can be in contact with the ceiling surface C in a substantially parallel plane or in such a manner that the front end portion slightly faces in the vertical direction.
因此，彈性構件10伴隨壓縮方向的彈性變形而(stand between)在器具本體1的背面側即點燈裝置罩35的背面側與天花板面C之間，照明器具本體1成為在彈性構件10的彈簧作用下被確實地保持並安裝於天花板面C的狀態。 Therefore, the elastic member 10 is elastically deformed in the compression direction between the back side of the fixture body 1, that is, between the back side of the lighting device cover 35 and the ceiling surface C, and the luminaire main body 1 becomes a spring at the elastic member 10. It is in a state of being reliably held and mounted on the ceiling surface C.
更詳細而言，借助彈性構件10的作用，能夠將天花板面C與各間接光光源部9的間隔保持為固定，從而能夠使從各間接光光源部9照射的光的出射角為固定。其結果，能夠實現配光特性的穩定化，從而可有效地照射天花板面C以進行間接照明。並且，彈性構件10對應於各間接光光源部9並且配設在其附近，因此可期待天花板面C與各間接光光源部9的間隔的固定化變得更為確實的效果。 More specifically, the distance between the ceiling surface C and each of the indirect light source units 9 can be kept constant by the action of the elastic member 10, and the emission angle of the light irradiated from each of the indirect light source units 9 can be made constant. As a result, it is possible to stabilize the light distribution characteristics, and it is possible to efficiently illuminate the ceiling surface C for indirect illumination. Further, since the elastic member 10 is disposed in the vicinity of the indirect light source unit 9 and is disposed in the vicinity thereof, it is expected that the fixing of the interval between the ceiling surface C and each of the indirect light source units 9 is more sure.
而且，在拆卸照明器具時，拆卸罩構件8，通過中心構件4的開口41來操作適配器A中所設的操作杆，以解除適配器A的卡止部A1的卡合，從而可拆卸。 Further, when the lighting fixture is removed, the cover member 8 is removed, and the operating lever provided in the adapter A is operated by the opening 41 of the center member 4 to release the engagement of the locking portion A1 of the adapter A, thereby being detachable.
在照明器具安裝於天花板面C的安裝狀態下，對點燈裝置3供給電力時，經由光源部2中的基板21而對發光元件22通電，各發光元件22點燈。從發光元件22朝向前表面側出射的光透過光源部罩25，經燈罩7擴散並透過後照射向外方。因此，可在規定的配光範圍內對下方進行照明。 When electric power is supplied to the lighting device 3 in a mounted state in which the lighting fixture is attached to the ceiling surface C, the light-emitting element 22 is energized via the substrate 21 in the light source unit 2, and each of the light-emitting elements 22 is turned on. The light emitted from the light-emitting element 22 toward the front surface side passes through the light source unit cover 25, is diffused through the globe 7, and is transmitted to the outside. Therefore, the lower side can be illuminated within a prescribed light distribution range.
而且，與此同時，對間接光光源部9通電時，各發光元件92點燈，從發光元件92朝斜上方出射的光透過透光性的罩93，並以從適配器引導部5的周圍放射的方式而主要照射至天花板面。因此，天花板面變得明亮，能夠提高空間的亮度感。 At the same time, when the indirect light source unit 9 is energized, the light-emitting elements 92 are turned on, and the light emitted obliquely upward from the light-emitting element 92 passes through the translucent cover 93 and is radiated from the periphery of the adapter guiding unit 5. The way is mainly to the ceiling. Therefore, the ceiling surface becomes bright, and the brightness of the space can be improved.
此時，能夠實現從間接光光源部9照射的光的配光特性的穩定化，從而能夠進行有效的間接照明。 At this time, stabilization of the light distribution characteristics of the light irradiated from the indirect light source unit 9 can be achieved, and effective indirect illumination can be performed.
當如此般使用發光元件22來作為光源部2中的光源 時，從發光元件22出射的光的指向性強，因此存在配光範圍變窄的傾向，但如本實施方式般，通過在本體1的背面側設置間接光光源部9，能夠提高空間的亮度感。因此，設置間接光光源部9成為在將光源部2的光源設為發光元件22時有效的手段。 When the light-emitting element 22 is used as a light source in the light source section 2 In the case where the light emitted from the light-emitting element 22 has high directivity, the light distribution range tends to be narrow. However, by providing the indirect light source unit 9 on the back side of the main body 1 as in the present embodiment, the brightness of the space can be improved. sense. Therefore, the provision of the indirect light source unit 9 is effective as a means for setting the light source of the light source unit 2 as the light-emitting element 22.
進而，這些光源部2及間接光光源部9是由偵測周圍的亮度並輸出檢測信號的光感測器6來控制其點燈狀態。 Further, the light source unit 2 and the indirect light source unit 9 control the lighting state by the photo sensor 6 that detects the surrounding brightness and outputs a detection signal.
由於基板21的背面側熱結合於本體1，因此從發光元件22產生的熱有效地傳導至本體1，並以大面積來散熱。而且，在本體1上形成有突出部12、13、14，因此能夠增大散熱面積，從而能夠進一步提高散熱效果。 Since the back side of the substrate 21 is thermally bonded to the body 1, heat generated from the light-emitting element 22 is efficiently conducted to the body 1 and dissipates heat over a large area. Moreover, since the protrusions 12, 13, and 14 are formed in the main body 1, the heat dissipation area can be increased, and the heat dissipation effect can be further improved.
除此以外，在本體1的突出部12上，載置安裝著點燈裝置罩35，因此熱從本體1傳導至點燈裝置罩35而促進散熱。 In addition to this, the lighting device cover 35 is placed on the protruding portion 12 of the main body 1. Therefore, heat is conducted from the main body 1 to the lighting device cover 35 to promote heat dissipation.
另一方面，從點燈裝置3產生的熱主要通過點燈裝置罩35內的空間的對流而散發。 On the other hand, the heat generated from the lighting device 3 is mainly radiated by the convection of the space in the lighting device cover 35.
此時，發光元件22與電路零件32朝背面方向空開隔離距離d而配置，而且，電路零件32位於發光元件22的內側，因此能以熱分離的方式而配置，從而能夠抑制相互的熱干涉。因此，能夠抑制發光元件22及電路零件32的過度的溫度上升。 At this time, since the light-emitting element 22 and the circuit component 32 are disposed apart from each other in the back surface direction by the isolation distance d, and the circuit component 32 is located inside the light-emitting element 22, it can be disposed in a thermally separated manner, thereby suppressing mutual thermal interference. . Therefore, excessive temperature rise of the light-emitting element 22 and the circuit component 32 can be suppressed.
進而，電路零件32中的發熱零件32H是遠離發光元件22而配置，因此能夠更有效地抑制相互的熱干涉。 Further, since the heat generating component 32H in the circuit component 32 is disposed away from the light emitting element 22, mutual thermal interference can be more effectively suppressed.
而且，從間接光光源部9的發光元件92產生的熱從 基板91的背面側傳導至點燈裝置罩35的側壁35a，進而還傳導至彈性構件10並得以散發。 Moreover, heat generated from the light-emitting element 92 of the indirect light source portion 9 is derived from The back side of the substrate 91 is conducted to the side wall 35a of the lighting device cover 35, and is further conducted to the elastic member 10 and is radiated.
如上所述，根據本實施方式，可提供一種照明器具，能夠抑制光源部中的發光元件與點燈裝置中的電路零件的相互的熱干涉。 As described above, according to the present embodiment, it is possible to provide a lighting fixture capable of suppressing mutual thermal interference between the light-emitting elements in the light source section and the circuit components in the lighting device.
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，任何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，當可作些許之更動與潤飾，故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。 Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
