蓋框部81係在Y軸方向長條狀之矩形板狀的框體，並與第1透光蓋70之複數片卡止片卡合。The cover frame 81 is a rectangular plate-shaped frame elongated in the Y-axis direction, and is engaged with a plurality of locking pieces of the first light-transmitting cover 70.
如圖2及圖4所示，傾斜部83係形成於蓋框部81的內緣側，並沿著蓋框部81之Y軸方向是長條。傾斜部83係在觀察在以X軸方向及Z軸方向所規定之平面剖開之截面的情況，以沿著第1遮光構件5及第2遮光構件6之各個的第1遮光蓋51的方式彎曲成圓弧形。 [位置關係]As shown in FIGS. 2 and 4, the inclined portion 83 is formed on the inner edge side of the cover frame portion 81 and is elongated along the Y-axis direction of the cover frame portion 81. The inclined portion 83 is to follow the first light-shielding cover 51 of each of the first light-shielding member 5 and the second light-shielding member 6 when observing a cross section cut in a plane defined by the X-axis direction and the Z-axis direction Bent into an arc shape. [Positional relationship]
其次，使用圖8，說明貫穿孔35c與第2光源122之位置關係。Next, using FIG. 8, the positional relationship between the through hole 35c and the second light source 122 will be described.
圖8係表示實施形態1之第1導光板3及第2光源122的平面圖。FIG. 8 is a plan view showing the first light guide plate 3 and the second light source 122 of the first embodiment.
如圖8所示，在平板部35所形成之貫穿孔35c係遮住在第1導光板3及第2導光板4內所行進的光。即，在彎曲部31導光而來的光向平板部35行進。在此時，所導光之光的一部分係藉貫穿孔35c遮住。因此，在第1導光板3及第2導光板4內，易形成陰影。若發生這種陰影，在第1光源121發光時，在從第1導光板3及第2導光板4之射出面35b所射出之光發生亮度斑，而美觀變差。As shown in FIG. 8, the through hole 35 c formed in the flat plate portion 35 shields the light traveling in the first light guide plate 3 and the second light guide plate 4. That is, the light guided by the curved portion 31 travels to the flat plate portion 35. At this time, a part of the guided light is blocked by the through hole 35c. Therefore, shadows are easily formed in the first light guide plate 3 and the second light guide plate 4. If such a shadow occurs, when the first light source 121 emits light, the light emitted from the emission surfaces 35b of the first light guide plate 3 and the second light guide plate 4 will have brightness irregularities, and the appearance will deteriorate.
從這種觀點，如圖8所示，在本實施形態，為了抑制陰影之發生，密集地配置在貫穿孔35c之周邊的複數之第2光源122。具體而言，在經由入射面31a與複數之貫穿孔35c的至少一個相對向的相對向區域H1，係比非相對向區域H2更密集地配置複數之第2光源122。即，密集地配置從貫穿孔35c在Y軸方向所配置並排列的複數之第2光源122的一部分。依此方式，藉由密集地配置複數之第2光源122的一部分，因為藉各個第2光源122所射出之光明亮地照射貫穿孔35c，而易消除因貫穿孔35c所產生之陰影。非相對向區域H2係相鄰之2個相對向區域H1之間的區域，未與貫穿孔35c相對向。From this point of view, as shown in FIG. 8, in this embodiment, in order to suppress the occurrence of shadows, the plurality of second light sources 122 are densely arranged around the through hole 35c. Specifically, in the facing region H1 facing at least one of the plurality of through holes 35c via the incident surface 31a, the plurality of second light sources 122 are arranged more densely than the non-opposing region H2. That is, a part of the plural second light sources 122 arranged and arranged in the Y-axis direction from the through hole 35c are densely arranged. In this way, by densely arranging a part of the plurality of second light sources 122, the light emitted by each of the second light sources 122 brightly irradiates the through holes 35c, and it is easy to eliminate the shadow generated by the through holes 35c. The non-opposing region H2 is a region between two adjacent opposing regions H1, and does not face the through hole 35c.
在非相對向區域H2所配置之複數之第2光源122係排列成隨著遠離相對向區域H1而間隔變大。此外，在非相對向區域H2，因為是被2個相對向區域H1所夾之區域，所以複數之第2光源122之間隔係正中央的間隔最寬，而兩端的間隔最窄。因此，在非相對向區域H2，因為複數之第2光源122排列成隨著遠離相對向區域H1而間隔變大，所以隨著遠離相對向區域H1而亮度逐漸地變弱。藉此，藉由在相對向區域H1與非相對向區域H2之邊界部分抑制亮度急速地變化，而抑制亮度不均的顯著。 [動作]The plurality of second light sources 122 arranged in the non-opposing area H2 are arranged so that the distance becomes larger as they move away from the opposing area H1. In addition, in the non-opposing region H2, because it is a region sandwiched by two opposing regions H1, the interval between the plurality of second light sources 122 is the widest in the center, and the interval between the two ends is the narrowest. Therefore, in the non-opposing region H2, since the plurality of second light sources 122 are arranged so as to be spaced larger as they move away from the opposing region H1, the brightness gradually decreases as they move away from the opposing region H1. Thereby, by suppressing a rapid change in brightness at the boundary portion between the facing region H1 and the non-opposing region H2, the brightness unevenness is suppressed from being noticeable. [action]
在這種照明裝置1，從複數之第1光源121所射出之光係藉透鏡蓋23的透鏡進行配光控制，在透光蓋7透光後，在照明裝置1之Z軸方向行進。又，從Y軸正方向側及Y軸負方向側之複數之第2光源122所射出的光係射入第1導光板3及第2導光板4之各個的入射面31a，並在彎曲部31及平板部35進行導光。在彎曲部31，係被內徑面31c及外徑面31b反射，或即使從外徑面31b射出亦被第1遮光構件5及第2遮光構件6反射的光射入。在平板部35進行導光之一部分的光係被稜鏡面35a反射而往射出面35b，再從射出面35b射出。又，在平板部35進行導光之其他部分的光係從稜鏡面35a射出，而對天花板照明。依此方式，在本照明裝置1，藉由從透光蓋7、第1導光板3以及第2導光板4之各個射出光，可對周圍照明。 [照明形態]In this kind of illuminating device 1, the light emitted from the plurality of first light sources 121 is controlled by the lens of the lens cover 23, and the light is transmitted through the transparent cover 7, and then travels in the Z-axis direction of the illuminating device 1. In addition, the light emitted from the plural second light sources 122 on the positive side of the Y-axis and the negative side of the Y-axis enters the incident surface 31a of each of the first light guide plate 3 and the second light guide plate 4, and is on the curved portion 31 and the flat plate part 35 conduct light. In the curved portion 31, the light reflected by the inner diameter surface 31c and the outer diameter surface 31b, or the light reflected by the first light shielding member 5 and the second light shielding member 6 even if emitted from the outer diameter surface 31b enters. The light system of a part of the light guided in the flat plate portion 35 is reflected by the scallop surface 35a and directed toward the exit surface 35b, and then exits from the exit surface 35b. In addition, the light system of the other part where the light is guided in the flat plate portion 35 is emitted from the ridge surface 35a to illuminate the ceiling. In this way, in the present lighting device 1, light is emitted from each of the light-transmitting cover 7, the first light guide plate 3, and the second light guide plate 4 to illuminate the surroundings.

如圖5所示，在照明裝置1之平面圖的情況，照明裝置1係具有光從第1導光板3射出之第1射出區域R1、光從第2導光板4射出之第2射出區域R2以及光從第3導光板203射出之第3射出區域R3。在本照明裝置1，從第1射出區域R1、第2射出區域R2以及第3射出區域R3所射出之光量係大致相等。即，在照明裝置1，進行大致均勻的發光。更具體而言，在第1射出區域R1、第2射出區域R2以及第3射出區域R3之各個，係進行抑制亮度斑之大致均勻的面發光，進而從第1射出區域R1、第2射出區域R2以及第3射出區域R3射出亮度大致相等的光。為了使從第1射出區域R1、第2射出區域R2以及第3射出區域R3所射出之各個的光量變成相等，圖3之控制部13控制電源部15，而複數之第1光源121及複數之第2光源122所射出之光量變成大致相等。As shown in FIG. 5, in the case of a plan view of the illuminating device 1, the illuminating device 1 has a first emission area R1 where light is emitted from the first light guide plate 3, a second emission area R2 where light is emitted from the second light guide plate 4, and The third emission area R3 where light is emitted from the third light guide plate 203. In the present lighting device 1, the amount of light emitted from the first emission area R1, the second emission area R2, and the third emission area R3 is substantially equal. That is, in the lighting device 1, substantially uniform light emission is performed. More specifically, in each of the first emission area R1, the second emission area R2, and the third emission area R3, substantially uniform surface light emission is performed with suppressed brightness spots, and furthermore, from the first emission area R1, the second emission area R2 and the third emission area R3 emit light having substantially equal brightness. In order to equalize the amount of light emitted from the first emission area R1, the second emission area R2, and the third emission area R3, the control unit 13 in FIG. 3 controls the power supply unit 15, and the plurality of first light sources 121 and the plurality of The amount of light emitted by the second light source 122 becomes substantially equal.
又，第1射出區域R1、第2射出區域R2以及第3射出區域R3之各個的面積係大致相等。各個之Y軸方向的長度及各個之X軸方向的長度各自大致相同。In addition, the area of each of the first emission region R1, the second emission region R2, and the third emission region R3 is substantially the same. The length of each Y-axis direction and the length of each X-axis direction are substantially the same.
又，在本照明裝置1，可在第1射出區域R1、第2射出區域R2以及第3射出區域R3之各個點燈，但是亦可進行將這些區域任意地組合的點燈。又，將第3射出區域R3分割成Y軸正方向側及Y軸負方向側，可進行分割照明。In addition, in the present lighting device 1, each of the first emission area R1, the second emission area R2, and the third emission area R3 can be lighted, but it is also possible to perform light-up combining these areas arbitrarily. In addition, the third emission region R3 is divided into the positive direction side of the Y-axis and the negative direction side of the Y-axis, so that divided illumination can be performed.
圖6(a)係表示使實施形態1之照明裝置1全部點燈之情況的模式圖。如圖3及圖6(a)所示，在本照明裝置1，控制部13使複數之第1光源121及複數之第2光源122點燈時，從第1導光板3、第2導光板4以及透光蓋7射出光。即，在本照明裝置1，藉由光從與第1導光板3及第2導光板4之各個的射出面35b對應之第1射出區域R1及第2射出區域R2、和從與透光蓋7之射出面對應的第3射出區域R3射出，對照明裝置1之X軸正方向側照明。Fig. 6(a) is a schematic diagram showing a state where the lighting device 1 of the first embodiment is all lit.

因此，若使在一方所排列之複數之第2光源122點燈，可藉從第1導光板3所射出之光對周圍照明。若使在另一方所排列之複數之第2光源122點燈，可藉從第2導光板4所射出之光對周圍照明。進而，若僅複數之第1光源121點燈，可藉從透光蓋7所射出之光對周圍照明。又，在本照明裝置1，將這些組合，亦可選擇性地點燈。即，從第1導光板3、第2導光板4以及透光蓋7之各個，藉個別或將選擇組合的照明形態，可射出對周圍照明的光。結果，在本照明裝置1，可在第1導光板3、第2導光板4以及透光蓋7之各個進行分割照明。Therefore, if the plural second light sources 122 arranged on one side are turned on, the light emitted from the first light guide plate 3 can illuminate the surroundings. If the plural second light sources 122 arranged on the other side are lit, the light emitted from the second light guide plate 4 can illuminate the surroundings. Furthermore, if only the plurality of first light sources 121 are lit, the light emitted from the transparent cover 7 can illuminate the surroundings. In addition, in the present lighting device 1, it is possible to selectively illuminate lights by combining these. That is, each of the first light guide plate 3, the second light guide plate 4, and the light-transmitting cover 7 can emit light to illuminate the surroundings individually or in combination. As a result, in the lighting device 1, the first light guide plate 3, the second light guide plate 4, and the light transmissive cover 7 can be separately illuminated.
因此，可在照明裝置1之發光區域局部地進行分割照明。Therefore, it is possible to perform segmented lighting locally in the light-emitting area of the lighting device 1.
尤其，例如僅使複數之第2光源122點燈，亦從第1導光板3及第2導光板4難發生第2光源122所造成之漏光。因此，在使第1光源121或第2光源122點燈的情況，抑制從第1導光板3及第2導光板4射出漏光所造成之不自然的光。依此方式，因為第1遮光構件5及第2遮光構件6抑制對第1導光板3及第2導光板4之漏光，所以從第1導光板3及第2導光板4可射出抑制了亮度斑的光。在這種照明裝置1，難使使用者覺得不協調感，美觀難變差。In particular, for example, if only a plurality of second light sources 122 are turned on, light leakage caused by the second light source 122 is unlikely to occur from the first light guide plate 3 and the second light guide plate 4. Therefore, when the first light source 121 or the second light source 122 is turned on, unnatural light caused by light leakage from the first light guide plate 3 and the second light guide plate 4 is suppressed. In this way, because the first light-shielding member 5 and the second light-shielding member 6 suppress light leakage to the first light guide plate 3 and the second light guide plate 4, light can be emitted from the first light guide plate 3 and the second light guide plate 4 and the brightness is suppressed. Spotted light. In this kind of lighting device 1, it is difficult to make the user feel uncomfortable, and the appearance is difficult to deteriorate.
又，在本實施形態之照明裝置1，更具備控制複數之第1光源121與複數之第2光源122的控制部13。而且，控制部13係使複數之第1光源121、一部分之第2光源122以及其他部分的第2光源122選擇性地點燈。In addition, the lighting device 1 of the present embodiment further includes a control unit 13 that controls a plurality of first light sources 121 and a plurality of second light sources 122. In addition, the control unit 13 selectively lights the plurality of first light sources 121, a part of the second light sources 122, and other parts of the second light sources 122.
若依據本實施形態，因為使複數之第1光源121、一部分之第2光源122以及其他部分的第2光源122選擇性地點燈，所以在本照明裝置1，可在第1導光板3、第2導光板4以及透光蓋7之各個進行分割照明。According to this embodiment, since the plural first light sources 121, some of the second light sources 122, and the other parts of the second light sources 122 are selectively lit, the lighting device 1 can be set on the first light guide plate 3, the second light source 122 2 Each of the light guide plate 4 and the light-transmitting cover 7 is separately illuminated.
又，在本實施形態之照明裝置1，在該照明裝置1之平面圖的情況，包括光從第1導光板3射出之第1射出區域R1、光從第2導光板4射出之第2射出區域R2以及光從第1光源121射出之第3射出區域R3。而且，從第1射出區域R1、第2射出區域R2以及第3射出區域R3所射出之光量係大致相等。In addition, in the illuminating device 1 of this embodiment, in the case of a plan view of the illuminating device 1, a first emission area R1 from which light is emitted from the first light guide plate 3 and a second emission area from which light is emitted from the second light guide plate 4 is included. R2 and the third emission area R3 where light is emitted from the first light source 121. In addition, the amounts of light emitted from the first emission area R1, the second emission area R2, and the third emission area R3 are substantially equal.
若依據本實施形態，從第1射出區域R1、第2射出區域R2以及第3射出區域R3所射出之光量係大致相等。因此，照明裝置1之美觀變佳。According to this embodiment, the amount of light emitted from the first emission area R1, the second emission area R2, and the third emission area R3 is substantially equal. Therefore, the appearance of the lighting device 1 is improved.
又，在本實施形態之照明裝置1，第1射出區域R1、第2射出區域R2以及第3射出區域R3之各個的面積係大致相等。In addition, in the lighting device 1 of the present embodiment, the areas of the first emission region R1, the second emission region R2, and the third emission region R3 are substantially the same.
在各個的面積相異的情況，例如為了使從第1射出區域R1、第2射出區域R2以及第3射出區域R3所射出之光量變成大致相等，必須使某個區域的光量變多或變少。在此情況，觀察照明裝置1時，某個區域就不均勻地發光。可是，若依據本實施形態，第1射出區域R1、第2射出區域R2以及第3射出區域R3之各個的面積係大致相等。因此，照明裝置1的美觀變佳。When the areas of each are different, for example, in order to make the amount of light emitted from the first emission area R1, the second emission area R2, and the third emission area R3 substantially equal, the amount of light in a certain area must be increased or decreased. . In this case, when the lighting device 1 is observed, a certain area emits light unevenly. However, according to this embodiment, the area of each of the first emission region R1, the second emission region R2, and the third emission region R3 is substantially the same. Therefore, the appearance of the lighting device 1 is improved.
又，在本實施形態之照明裝置1，第1遮光構件5及第2遮光構件6係具有反射光的光反射功能。In addition, in the lighting device 1 of the present embodiment, the first light-shielding member 5 and the second light-shielding member 6 have a light reflection function of reflecting light.
若依據本實施形態，因為第1光源121所射出之光係在第1遮光構件5及第2遮光構件6被反射，即使在因配線構件120a而發生陰影的位置，亦可抑制這種陰影的發生。又，即使光從第1導光板3及第2導光板4之彎曲部31的外徑面31b射出，亦在第1遮光構件5及第2遮光構件6被反射，而可射入彎曲部31。According to the present embodiment, since the light emitted by the first light source 121 is reflected by the first light shielding member 5 and the second light shielding member 6, even at a position where shadows are generated by the wiring member 120a, such shadowing can be suppressed occur. In addition, even if light is emitted from the outer diameter surface 31b of the curved portion 31 of the first light guide plate 3 and the second light guide plate 4, it is reflected by the first light shielding member 5 and the second light shielding member 6, and can enter the curved portion 31 .
又，在本實施形態之照明裝置1，發光模組21係至少接受複數之第1光源121之控制的信號所通過之第2開口部120b被形成於發光模組21的端部側。而且，一部分之第1光源121係作為常夜燈點燈，並被配置於第2開口部120b的周邊。In addition, in the lighting device 1 of this embodiment, the light-emitting module 21 is formed on the end side of the light-emitting module 21 through the second opening 120b through which at least signals controlled by the plural first light sources 121 pass. In addition, a part of the first light source 121 is turned on as a night light, and is arranged around the second opening 120b.
例如，在第2開口部120b位於第1開口部20a之周邊的情況，無法配置第1光源121及第2光源122的非發光區域就偏向中央部分，而可能非發光區域變大。因此，為了抑制因非發光區域而產生的亮度斑，而從照明裝置1射出均勻的光，必須在第1開口部20a及第2開口部120b的周邊使第2光源122的密度變大，或必須使藉透鏡蓋23之配光控制變成過度，而藉透鏡蓋23之配光控制變成困難。For example, when the second opening 120b is located at the periphery of the first opening 20a, the non-light-emitting area where the first light source 121 and the second light source 122 cannot be arranged is shifted to the central portion, and the non-light-emitting area may become larger. Therefore, in order to suppress the brightness unevenness caused by the non-light-emitting area, and to emit uniform light from the lighting device 1, it is necessary to increase the density of the second light source 122 around the first opening 20a and the second opening 120b, or The light distribution control by the lens cover 23 must be excessive, and the light distribution control by the lens cover 23 has become difficult.
因此，藉由在發光模組21的端部側形成第2開口部120b，亦不會使第2光源122之配置的密度變大。又，必須使藉透鏡蓋23之配光控制變成過度之配光控制的困難性難變高。Therefore, by forming the second opening 120b on the end side of the light-emitting module 21, the arrangement density of the second light sources 122 will not increase. In addition, it is difficult to make the light distribution control by the lens cover 23 excessively difficult.
又，亦具有藉遙控器之控制將複數之第2光源122調整成常夜燈的功能，並將接收遙控器所傳送之信號的接收部14配置於開口部之Z軸方向側。若將作為常夜燈點燈之複數之第2光源122配置於接收部14的附近，則難對操作性給與不協調感。In addition, it also has the function of adjusting the plurality of second light sources 122 into night lights under the control of the remote control, and the receiving unit 14 that receives the signal transmitted by the remote control is arranged on the Z-axis direction side of the opening. If the plurality of second light sources 122 for lighting of the night lights are arranged in the vicinity of the receiving unit 14, it is difficult to give a sense of discomfort to the operability.
又，在本實施形態之照明裝置1，第1導光板3及第2導光板4各自具有光射出的射出面35b、與射出面35b相反側的稜鏡面35a以及光射入的入射面31a。又，在第1導光板3及第2導光板4之入射面31a側的端部，沿著入射面31a排列從射出面35b貫穿至稜鏡面35a的複數之貫穿孔35c。而且，在經由入射面31a與複數之貫穿孔35c之至少一個相對向的相對向區域，比非相對向區域更密集地配置複數之第2光源122。In addition, in the illuminating device 1 of the present embodiment, the first light guide plate 3 and the second light guide plate 4 each have an emission surface 35b from which light is emitted, a beam surface 35a on the opposite side of the emission surface 35b, and an incident surface 31a through which light enters. In addition, at the ends of the first light guide plate 3 and the second light guide plate 4 on the entrance surface 31a side, a plurality of through holes 35c penetrating from the exit surface 35b to the ridge surface 35a are arranged along the entrance surface 31a. In addition, in the opposing area that opposes at least one of the plurality of through holes 35c via the incident surface 31a, the plurality of second light sources 122 are densely arranged than the non-opposing area.
依此方式，因為在經由入射面31a與複數之貫穿孔35c之至少一個相對向的相對向區域，比非相對向區域更密集地配置複數之第2光源122，所以藉複數之第1光源121照明貫穿孔35c。藉此，在以一個第2光源122照射之情況所形成的陰影係藉來自其他的第2光源122的光所消除。因此，可抑制由安裝用之貫穿孔35c所引起之第1導光板3及第2導光板4內之陰影的發生。因此，可提高在第1導光板3及第2導光板4之各個的射出面35b之光的均勻性。 又，在本實施形態之照明裝置1，第1射出區域R1與第2射出區域R2係被配置成對第3射出區域R3對稱。 又，本實施形態之照明裝置1係更具備長條狀之透鏡蓋23，該透鏡蓋23係對複數之第1光源121所射出之光進行配光控制。而且，第1遮光構件5及第2遮光構件6係具有沿著透鏡蓋23之端緣突出的突出卡合部51c。 (實施形態2)In this way, the plurality of second light sources 122 are arranged more densely than the non-opposing area in at least one of the opposed areas through the incident surface 31a and the plurality of through holes 35c, so the plurality of first light sources 121 are borrowed Illumination through hole 35c. Thereby, the shadow formed when illuminated by one second light source 122 is eliminated by the light from the other second light source 122. Therefore, the occurrence of shadows in the first light guide plate 3 and the second light guide plate 4 caused by the through hole 35c for mounting can be suppressed. Therefore, the uniformity of light on the emission surface 35b of each of the first light guide plate 3 and the second light guide plate 4 can be improved. In addition, in the lighting device 1 of the present embodiment, the first emission area R1 and the second emission area R2 are arranged symmetrically to the third emission area R3. In addition, the illuminating device 1 of this embodiment is further provided with an elongated lens cover 23 for controlling the light distribution of the light emitted by the plurality of first light sources 121. In addition, the first light shielding member 5 and the second light shielding member 6 have a protruding engagement portion 51 c protruding along the edge of the lens cover 23. (Embodiment 2)
