Further, the frame 15 is mounted on the upper surface of the fixture body 11, the illuminance sensor 63 is electrically connected to the lighting circuit 18, and the sensor housing 65 for holding the illuminance sensor 63 is mounted on the appliance. The upper surface of the body 11 and the frame 15.

在使器具本體11的基板配置部22以朝向上方的方式上下反轉的狀態下,在基板配置部22上載置各基板12,使基板12的各嵌合孔34凹凸嵌合於基板配置部22的各凸部30。由此,基板12沿器具本體11的基板配置部22的面的方向(水平方向)上的位置得以定位保持。進而,進行兩基板12間或基板12與點燈電路18之間的配線。 In a state in which the substrate arrangement portion 22 of the luminaire main body 11 is vertically reversed, the respective substrates 12 are placed on the substrate arranging portion 22, and the fitting holes 34 of the substrate 12 are concave-convex and fitted to the substrate arranging portion 22 Each convex portion 30. Thereby, the position of the substrate 12 in the direction (horizontal direction) of the surface of the substrate arrangement portion 22 of the luminaire main body 11 is positioned and held. Further, wiring between the two substrates 12 or between the substrate 12 and the lighting circuit 18 is performed.

一面以覆蓋基板12的方式罩上透光外罩13,一面使透光外罩13的各爪部44插通於器具本體11的各爪插通孔27中,並使透光外罩13向安裝旋動方向進行旋動,由此使各爪部44的前端乘坐上器具本體11的背面側並將透光外罩13朝向器具本體11牽引。此時,透光外罩13抵接於基板12,而將基板12按壓在器具本體11上。而且,當各爪部44卡在器具本體11的背面側時,以將基板12夾持在器具本體11與透光外罩13之間的狀態來固定器具本體11與透光外罩13。 The light-transmitting cover 13 is covered with the cover substrate 12, and the claw portions 44 of the light-transmitting cover 13 are inserted into the respective claw insertion holes 27 of the device body 11, and the light-transmitting cover 13 is rotated toward the mounting. The direction is rotated, whereby the front end of each of the claw portions 44 rides on the back side of the upper body 11 and the light-transmitting cover 13 is pulled toward the instrument body 11. At this time, the light-transmitting cover 13 abuts against the substrate 12, and the substrate 12 is pressed against the device body 11. Further, when each of the claw portions 44 is caught on the back side of the luminaire main body 11, the luminaire main body 11 and the light transmissive outer cover 13 are fixed in a state in which the substrate 12 is sandwiched between the luminaire main body 11 and the light transmissive outer cover 13.

將螺釘穿過透光外罩13的螺釘插通孔46並旋入到器具本體11的安裝孔28中而固定,從而限制透光外罩13向相對於安裝旋動方向相反的拆卸旋動方向旋動。 The screw is inserted through the screw insertion hole 46 of the light-transmitting cover 13 and screwed into the mounting hole 28 of the fixture body 11 to be fixed, thereby restricting the light-transmitting cover 13 from being rotated in the disassembly and rotation direction opposite to the mounting rotation direction. .

以覆蓋基板12及透光外罩13等的方式將燈罩14罩在器具本體11上,並使燈罩14向規定的安裝旋動方向旋動,由此將燈罩14安裝在燈罩安裝配件31上。 The lamp cover 14 is placed on the luminaire main body 11 so as to cover the substrate 12, the light-transmitting cover 13, and the like, and the lamp cover 14 is rotated in a predetermined mounting rotation direction, whereby the lamp cover 14 is attached to the lamp cover mounting metal fitting 31.

此外,照明器具10的組裝順序並不限定於所述順序。 Further, the order of assembly of the lighting fixture 10 is not limited to the order described.

然後,在設置照明器具10時,將預先卸除了燈罩14的 照明器具10的接合器導件17安裝在接合器上,該接合器安裝在天花板面的天花板插座上。將從接合器導出的配線與點燈電路18側連接,從而將天花板插座與點燈電路18電性連接。將燈罩14安裝在器具本體11上。 Then, when the lighting fixture 10 is set, the lampshade 14 will be removed in advance. The adapter guide 17 of the lighting fixture 10 is mounted on an adapter that is mounted on a ceiling socket on the ceiling. The wiring led out from the adapter is connected to the lighting circuit 18 side to electrically connect the ceiling socket to the lighting circuit 18. The lamp cover 14 is mounted on the fixture body 11.

然後,通過將商用交流電源供給至點燈電路18,而從點燈電路18對多個LED元件35供給點燈電力,從而將多個LED元件35點亮。 Then, by supplying the commercial alternating current power to the lighting circuit 18, the lighting power is supplied to the plurality of LED elements 35 from the lighting circuit 18, thereby lighting the plurality of LED elements 35.

多個LED元件35所產生的光由透光外罩13的配光控制體41控制配光而入射至燈罩14,並透過燈罩14而照射至照明空間。 The light generated by the plurality of LED elements 35 is controlled by the light distribution control body 41 of the light-transmitting cover 13 to be incident on the cover 14 and transmitted through the cover 14 to the illumination space.

另外,利用照度感測器63檢測設置有照明器具10的照明空間的亮度,且點燈電路18自動地調整LED元件35的輸出。 Further, the luminance of the illumination space in which the lighting fixture 10 is provided is detected by the illuminance sensor 63, and the lighting circuit 18 automatically adjusts the output of the LED element 35.

另外,LED元件35所產生的熱從基板12被導熱至器具本體11,並從器具本體11高效地散熱。另一方面,點燈電路18所產生的熱傳遞給盒體16,而從盒體16高效地散熱。因此,LED元件35所產生的熱與點燈電路18所產生的熱較少相互干涉,而可使各自產生的熱高效地散熱。 Further, the heat generated by the LED element 35 is thermally conducted from the substrate 12 to the fixture body 11 and efficiently dissipated heat from the fixture body 11. On the other hand, the heat generated by the lighting circuit 18 is transmitted to the casing 16 to efficiently dissipate heat from the casing 16. Therefore, the heat generated by the LED elements 35 and the heat generated by the lighting circuit 18 are less likely to interfere with each other, and the heat generated by each of them can be efficiently dissipated.

在以這種方式構成的照明器具10中,如圖1(a)所示,與器具本體11的中央相對向的燈罩14的中央部分14a配置在比交點P的位置更背離器具本體11側的位置上,該交點P是從圓周上的各LED元件35起與突出部21的周邊部相接而延伸的切線,即假想線48,在器具本體11的中央側交叉的交點。 In the lighting fixture 10 configured as described above, as shown in Fig. 1(a), the central portion 14a of the globe 14 facing the center of the fixture body 11 is disposed further away from the fixture body 11 side than the position of the intersection P. In the position, the intersection P is a tangent extending from the LED elements 35 on the circumference to the peripheral portion of the protruding portion 21, that is, the imaginary line 48 intersecting at the center side of the fixture body 11.

假設在燈罩14的中央部分14a位於比交點P的位置更靠近器具本體11的位置上的情況下,來自LED元件35的光被突出部21遮擋而產生的影子會映射在燈罩14的中央部分14a,而使燈罩14的中央部分14a變暗。 Assuming that the central portion 14a of the globe 14 is located closer to the fixture body 11 than the position of the intersection P, the shadow generated by the light from the LED element 35 being blocked by the projection 21 is mapped to the central portion 14a of the globe 14. The central portion 14a of the globe 14 is darkened.

通過將燈罩14的中央部分14a配置在比交點P的位置更背離器具本體11側的位置上,而可防止影子映射在燈罩14上,從而可使燈罩14整體的亮度均勻。 By arranging the central portion 14a of the globe 14 at a position away from the apparatus body 11 side from the position of the intersection point P, it is possible to prevent the shadow from being mapped on the globe 14, so that the brightness of the entire globe 14 can be made uniform.

另外,在圖1(a)中表示了天花板面與LED元件35之間的距離較寬,且突出部21從器具本體11的下表面的突出量較小的照明器具10,而在圖1(b)中表示了天花板面與LED元件35之間的距離較窄,且突出部21從器具本體11的下表面的突出量較大的照明器具10。在圖1(b)所示的照明器具10的情況下,通過將燈罩14的中央部分14a配置在比交點P的位置更背離器具本體11側的位置上,也能夠防止影子映射在燈罩14上,從而可使燈罩14整體的亮度均勻。 Further, in Fig. 1(a), the lighting fixture 10 having a wide distance between the ceiling surface and the LED element 35 and having a small projection amount from the lower surface of the fixture body 11 is shown in Fig. 1 (Fig. 1 (a). The lighting fixture 10 in which the distance between the ceiling surface and the LED element 35 is narrow and the protruding portion 21 protrudes from the lower surface of the fixture body 11 is shown in b). In the case of the lighting fixture 10 shown in FIG. 1(b), by arranging the central portion 14a of the globe 14 at a position away from the apparatus body 11 side from the position of the intersection P, it is possible to prevent the shadow from being mapped on the globe 14. Therefore, the brightness of the entire cover 14 can be made uniform.

另外,在LED元件35在同心圓上排列有多行的情況下,通過將從最內周行的LED元件35起與突出部21的周邊部相接的假想線48的交點P設為基準,而可防止影子映射在燈罩14上,從而可使燈罩14整體的亮度均勻 In addition, when the LED elements 35 are arranged in a plurality of rows on the concentric circles, the intersection point P of the imaginary line 48 that is brought into contact with the peripheral portion of the protruding portion 21 from the innermost circumferential LED element 35 is used as a reference. The shadow can be prevented from being mapped on the lamp cover 14, so that the brightness of the lamp cover 14 can be uniform.

另外,配光控制體41以基準軸43為中心而形成為在器具本體11的中央側方向與相反的外側方向上軸對稱的剖面形狀,並且基準軸43位於比LED元件35的發光部的中心35a更靠器具 本體11的外側方向。將利用該配光控制體41的配光圖示於圖4。在圖4中,0°為正下方向,正(plus)角度側為器具本體11的中央側方向,負(minus)角度側為器具本體11的外側方向。 Further, the light distribution control body 41 is formed in a cross-sectional shape that is axially symmetrical with respect to the outer side direction of the luminaire main body 11 in the center direction of the luminaire main body 11 and the reference shaft 43 is located at the center of the light-emitting portion of the LED element 35. 35a depends on the appliance The outer direction of the body 11. The light distribution diagram using the light distribution control body 41 is shown in Fig. 4 . In FIG. 4, 0° is the direct downward direction, the plus angle side is the center side direction of the luminaire main body 11, and the minus angle side is the outer side direction of the luminaire main body 11.

由圖4可知,器具本體11的中央側方向的光度與外側方向的光度相比變大。其原因在於,因為LED元件35的發光部靠近配光控制體41的內周側,所以從配光控制體41的內周側出射的光變得多於從外周側出射的光。因為在器具本體11的中央設置著向天花板插座安裝的安裝構造或存在收容點燈電路18的突出部21,所以從配置在該突出部21的周圍的LED元件35起到燈罩14的中央部分14a之間的距離拉開,但通過具有這種配光特性,而使燈罩14的中央部分14a變亮,從而可使燈罩14整體的亮度均勻。 As can be seen from FIG. 4, the illuminance in the center side direction of the luminaire main body 11 becomes larger than the illuminance in the outer direction. This is because the light-emitting portion of the LED element 35 is close to the inner peripheral side of the light distribution control body 41, so that the light emitted from the inner peripheral side of the light distribution control body 41 becomes more light emitted from the outer peripheral side. Since the mounting structure for mounting to the ceiling socket or the protruding portion 21 for accommodating the lighting circuit 18 is provided in the center of the fixture body 11, the central portion 14a of the globe 14 is provided from the LED element 35 disposed around the protruding portion 21. The distance between them is opened, but by having such a light distribution characteristic, the central portion 14a of the globe 14 is brightened, so that the brightness of the entire cover 14 can be made uniform.

此外,使配光控制體41向器具本體11的中央側方向的配光的峰值(peak)與所述交點P一致。因此,可使燈罩14的中央部分14a變亮,從而可使燈罩14整體的亮度均勻。 Further, the peak of the light distribution of the light distribution control body 41 toward the center side of the luminaire main body 11 coincides with the intersection point P. Therefore, the central portion 14a of the globe 14 can be made bright, so that the brightness of the entire cover 14 can be made uniform.

另外,因為在配光控制體41的比基準軸43更靠外周側的入射面41a及出射面41b中的至少一者中形成有光擴散面,所以可減少燈罩14周邊部的亮度不均,從而可使燈罩14整體的亮度均勻。 In addition, since the light diffusing surface is formed in at least one of the incident surface 41a and the emitting surface 41b on the outer peripheral side of the light distribution control body 41, the unevenness of brightness in the peripheral portion of the globe 14 can be reduced. Thereby, the brightness of the entire cover 14 can be made uniform.

進而,該光擴散面的擴散特性是以擴散度隨著從器具本體11的中央側方向朝向外側方向而逐漸增大的方式形成。另外,同心圓上的多行配光控制體41中,外周側的配光控制體41與內 周側的配光控制體41相比以光擴散面的擴散度變大的方式形成。由此,使擴散特性的有無邊界不明顯,從而可使燈罩14整體的亮度均勻。 Further, the diffusion characteristic of the light diffusion surface is formed such that the degree of diffusion gradually increases from the center side direction of the luminaire main body 11 toward the outer direction. Further, in the multi-row light distribution control body 41 on the concentric circle, the light distribution control body 41 on the outer circumference side and the inside The light distribution control body 41 on the circumferential side is formed to have a larger degree of diffusion of the light diffusion surface. Thereby, the presence or absence of the boundary of the diffusion characteristics is not conspicuous, and the brightness of the entire globe 14 can be made uniform.

此外,照明器具並不限定於圓形的吸頂燈,也可以應用於四邊形或多邊形的照明器具。 Further, the lighting fixture is not limited to a circular ceiling lamp, and may be applied to a quadrilateral or polygonal lighting fixture.
