[0002] According to market demand, lamps have become more and more diversified. A hanging transparent lamp can produce both lighting and aesthetic effects.

[0003] However, when multiple transparent lamps need to be connected to each other, they are limited by the frame design of the lamps themselves, and cannot be connected to form a continuous shape, resulting in a discontinuous light-emitting surface after connection, thus lacking consistency in appearance and being prone to dark areas.

[0004] In particular, hanging lamps at different levels cannot be connected to each other, and cannot produce a continuous light-emitting surface with ups and downs. SUMMARY

[0005] Therefore, the purpose of the present disclosure is to provide a lamp with curved lighting function, which can be connected to each other or connected to other flat lamps to form a lamp system with different appearances, and the lamp system can also form a height difference in at least one direction, so it can be applied to environment lighting with different height changes in that direction.

The first lamp and the second lamp are connected to each other through an electrical connection assembly. The first light emitting direction of the first lamp is different from the second light emitting direction of the second lamp.

[0016] According to an embodiment of the present disclosure, the light guide plate of the first lamp and another light guide plate of the second lamp are continuously jointed to form a continuous light emitting surface.

[0017] According to an embodiment of the present disclosure, the first lamp further includes a carrier arranged on the two side covers, wherein the carrier has a distance from the light guide plate, and the electrical connection assembly is arranged on the carrier.

[0034] Figure 8 This is a schematic diagram illustrating a lighting system according to another embodiment of the present disclosure. Detailed Implementation

[0035] Please refer to the following at the same time Figure 1 This is a schematic diagram illustrating a lighting system according to one embodiment of the present disclosure. The lighting system disclosed herein is mainly formed by connecting at least two sets of lamps in series. (The following is a simplified description of the schematic diagram.) Figure 1 Let's take lighting system 100 as an example to illustrate. Figure 1 As shown, the lighting system 100 of this embodiment is composed of lamps 200, 300, 400, and 500 connected in series. Lamps 200 and 500 are essentially identical flat-plate lamps, while lamps 300 and 400, in addition to their illumination function, also serve as connecting lamps. Lamps 300 and 400 are curved surfaces. In one embodiment, lamp 300 is a concave lamp, and lamp 400 is an apical lamp. Therefore, by providing connecting lamps between multiple flat-plate lamps, or by connecting multiple connecting lamps in series, a lighting system with different curvature appearances and a continuous illumination surface can be formed.

[0036] Please refer to the following as well. Figure 2A and Figure 2B , Figure 2A This is an exploded view illustrating a lamp according to the first embodiment of the present disclosure. Figure 2B This is a side view illustrating a carrier according to a first embodiment of the present disclosure. The luminaire 300 includes two opposing side covers 310, a carrier 320, a light guide plate 330, at least one light source 340, an electrical connection assembly 350, and a top cover 360. The light guide plate 330 is primarily supported on the side covers 310. The light source 340 is disposed inside the side covers 310 and adjacent to the light guide plate 330 to provide light into the light guide plate 330. The carrier 320 is disposed on the side covers 310, and the electrical connection assembly 350 is disposed on the carrier 320, forming a power circuit with the light source 340. The top cover 360 covers the carrier 320, protecting the electrical connection assembly 350 disposed in the carrier 320, and a suspension wire can be disposed on the top cover 360.

[0037] Please refer to the following at the same time Figure 2A and Figure 3 ,in Figure 3 It is drawn along Figure 1A-A cross-sectional view of the light fixture 300. In an embodiment, the side cover 310 is provided with a partition 311, and the partition 311 separates the side cover 310 into an upper space A1 and a lower space A2. The carrier 320 is disposed in the upper space A1. In addition, the light guide plate 330 has a light-in surface 331 and a light-out surface 332 connected to the light-in surface 331. The light source 340 is disposed in the lower space A2, and the portion of the light guide plate 330 close to the light-in surface 331 is disposed in the lower space A2 and faces the light source 340. That is, the carrier 320 and the light guide plate 330 are separated by the partition 311, so that a distance is formed between the carrier 320 and the light guide plate 330. Therefore, the carrier 320 disposed in the upper space A1 is used to accommodate the electrical connection assembly 350 or other components required by the light fixture 300, so as to avoid affecting the light-out effect of the light guide plate 330 disposed in the lower space A2, and thus making the light guide plate 330 look more transparent in visual effect.

[0038] In the embodiment, the light-out surface 332 of the light guide plate 330 is curved, and the side cover 310 is an arc-shaped side cover corresponding to the curved arc of the light guide plate 330. In an example, the light source 340 can be a light-emitting diode light bar, and the substrate shape of the light source 340 can correspond to the arc of the side cover 310 so as to be put into the side cover 310. In an embodiment, the carrier 320 can also be designed as an arc-shaped carrier corresponding to the curved arc of the light guide plate 330. For example Figure 2A and Figure 2B As shown, the carrier 320 looks like a concave U-shaped from the side, and includes an additional circuit board 321 and two connecting walls 322. The additional circuit board 321 has two arc edges 321a oppositely arranged and two side edges 321b oppositely arranged, wherein the arc of the arc edges 321a is the same as the arc of the light-out surface 332 of the light guide plate 330, and the two connecting walls 322 are respectively arranged on the two side edges 321b without arc. In an embodiment, the connecting wall 322 is a plane, which is beneficial to engage with the connecting wall of the next light fixture, and has an included angle B1 between the two connecting walls 322 oppositely arranged, that is, the two connecting walls 322 are respectively inclined at an angle relative to the additional circuit board 321 and are not parallel to each other.

[0039] Please also refer to Figure 2A and Figure 4 , Figure 4 is a schematic view Figure 1Fig. 3 is a partial device schematic diagram showing the connection state of the lamp shown in Fig. 1. In this embodiment, the electrical connection assembly 350 comprises a first connector 351 and a second connector 352 disposed on opposite sides of the carrier 320, respectively, and the first connector 351 and the second connector 352 can be electrically connected to each other by, for example, an electric wire (not shown in the figure). At least one of the first engagement direction D1 of the first connector 351 and the second engagement direction D2 of the second connector 352 is designed to be not perpendicular to the Z-axis direction but to form an angle with the Z-axis direction. In this disclosure, the Z-axis direction is defined as the direction perpendicular to the ceiling (or the hanging surface of the lamp), that is, when the flat panel lamp (for example, the lamp 200 and the lamp 500 shown in Figs. 2 and 5) is normally arranged horizontally, the axis direction perpendicular to the light emitting surface of the flat panel lamp is the Z-axis direction. In an example, the first connector 351 and the second connector 352 of the lamp 300 are disposed on the opposite connection walls 322 of the carrier 320, respectively, and the first engagement direction D1 of the first connector 351 and the second engagement direction D2 of the second connector 352 are different, so the extension direction (or the light emitting direction) of the lamp 400 that is connected to the first connector 351 of the lamp 300 is naturally different from the extension direction (or the light emitting direction) of the lamp 200 that is connected to the second connector 352. Figure 1 Fig. 4 is a partial device schematic diagram showing the connection state of the lamp shown in Fig. 1. In this embodiment, the electrical connection assembly 350 comprises a first connector 351 and a second connector 352 disposed on opposite sides of the carrier 320, respectively, and the first connector 351 and the second connector 352 can be electrically connected to each other by, for example, an electric wire (not shown in the figure). At least one of the first engagement direction D1 of the first connector 351 and the second engagement direction D2 of the second connector 352 is designed to be not perpendicular to the Z-axis direction but to form an angle with the Z-axis direction. In this disclosure, the Z-axis direction is defined as the direction perpendicular to the ceiling (or the hanging surface of the lamp), that is, when the flat panel lamp (for example, the lamp 200 and the lamp 500 shown in Figs. 2 and 5) is normally arranged horizontally, the axis direction perpendicular to the light emitting surface of the flat panel lamp is the Z-axis direction. In an example, the first connector 351 and the second connector 352 of the lamp 300 are disposed on the opposite connection walls 322 of the carrier 320, respectively, and the first engagement direction D1 of the first connector 351 and the second engagement direction D2 of the second connector 352 are different, so the extension direction (or the light emitting direction) of the lamp 400 that is connected to the first connector 351 of the lamp 300 is naturally different from the extension direction (or the light emitting direction) of the lamp 200 that is connected to the second connector 352.

[0040] Please refer to Figure 1 , Figure 5A and Figure 5B , wherein Figure 5A is an exploded schematic diagram showing a lamp according to the second embodiment of the present disclosure, Figure 5B is a side view showing a carrier according to the second embodiment of the present disclosure. The lamp 400 comprises two oppositely disposed side covers 410, a carrier 420, a light guide plate 430, at least one light source 440, an electrical connection assembly 450, and an upper cover 460. The light guide plate 430 is carried on the side cover 410. The light source 440 is disposed inside the side cover 410 and adjacent to the light guide plate 430 to provide light into the light guide plate 430. The carrier 420 is disposed on the side cover 410, the electrical connection assembly 450 is disposed on the carrier 420, and forms an electrical circuit with the light source 440. The upper cover 460 covers the carrier 420, can protect the electrical connection assembly 450 disposed in the carrier 420, and can provide a hanging wire thereon.

[0041] Please continue to refer to Figure 5AIn this embodiment, the side cover 410 is provided with a partition 411, and the partition 411 separates the side cover 410 into an upper space A3 and a lower space A4. The carrier 420 is arranged in the upper space A3. In addition, the light guide plate 430 has a light inlet face 431 and a light outlet face 432 connected to the light inlet face 431. The light source 440 is arranged in the lower space A4, and the part of the light guide plate 430 close to the light inlet face 431 is also arranged in the lower space A2 and faces the light source 440. That is, the carrier 420 and the light guide plate 430 are separated by the partition 411, so that a distance is formed between the carrier 420 and the light guide plate 430. Therefore, the carrier 420 arranged in the upper space A3 is used to accommodate the electrical connection assembly 450 or other required elements of the lamp 400, so as to avoid affecting the light outlet effect of the light guide plate 430 arranged in the lower space A4, and make the light guide plate 430 look more transparent in visual effect.

[0042] In this embodiment, the light outlet face 432 of the light guide plate 430 is a curved face, and the side cover 410 is an arc-shaped side cover corresponding to the curvature of the light guide plate 430. The carrier 420 can also be designed as an arc-shaped carrier corresponding to the curvature of the light guide plate 430. Therefore, when the lamp 400 with the arc-shaped design is connected with the lamp 300, the side cover 410 of the lamp 400 and the side cover 310 of the lamp 300 can form a continuous frame structure, and the light guide plate 430 of the lamp 400 and the light guide plate 330 of the lamp 300 can be connected with each other and form a continuous light outlet face. Figure 5A Figure 5B As shown in the figures, the carrier 420 is a U-shaped carrier with a concave upper face, which includes an additional circuit board 421 and two connecting walls 422. The additional circuit board 421 has two arc edges 421a arranged oppositely and two side edges 421b arranged oppositely. The curvature of the arc edges 421a is the same as that of the light outlet face 432 of the light guide plate 430. The two connecting walls 422 are respectively arranged on the two side edges 421b. In an embodiment, the connecting walls 422 are flat, which is beneficial to the connection with the connecting walls of the next lamp. In addition, the connecting walls 422 arranged oppositely have an included angle B2, that is, the two connecting walls 422 are respectively inclined at an angle with respect to the additional circuit board 421 and are not parallel to each other.

[0043] Please also refer to Figure 4 Figure 5A ​​In the present embodiment, the electrical connection assembly 450 comprises a first connector 451 and a second connector 452 disposed on opposite sides of the carrier 420, respectively. At least one of the first engagement direction D3 of the first connector 451 and the second engagement direction D4 of the second connector 452 is designed to be not perpendicular to the Z-axis, but to form an angle with the Z-axis. In the present embodiment, the first connector 451 and the second connector 452 of the luminaire 400 are disposed on opposite connection walls 422 of the carrier 420, respectively, i.e. the first connector 451 and the second connector 452 are disposed to engage other electrical connectors of other luminaires, and the first engagement direction D3 of the first connector 451 and the second engagement direction D4 of the second connector 452 are different. Thus, as shown in Figure 4 Fig. 3, by directly combining the luminaire 300 with the luminaire 400, a luminaire appearance with a curvature can be formed. Furthermore, by combining the flat luminaires, such as the luminaire 200 and the luminaire 500, with the luminaire 300 and the luminaire 400, respectively, a Z-shaped luminaire system 100 as shown in Figure 1 Fig. 4 can be formed. Moreover, by combining the luminaires 300 and 400 with a height difference in the Z-axis between the luminaire 200 and the luminaire 500, the luminaire 200 and the luminaire 500 can be located at different horizontal heights, thereby providing environmental lighting adapted to different Z-axis height variations. In another example, when the flat luminaires 200 and 500 are combined with the luminaires 300 and 400, respectively, because the light emitting surfaces of the luminaires 300 and 400 are inclined with respect to the Z-axis and form angles with the Z-axis that are not equal to 90°, respectively, a height difference between the flat luminaires 200 and 500 can be generated.

[0044] In particular, the luminaire system of the present disclosure is to dispose at least one luminaire with a curved surface between two flat luminaires, and the two engagement directions between the luminaire with a curved surface and the two flat luminaires are misaligned with each other, such as misaligned in the Z-axis in the present embodiment. As shown in Figure 4 Fig. 3, the second engagement direction D2 of the second connector 352 of the luminaire 300 can be designed to not coincide with the first engagement direction D3 of the first connector 451 of the luminaire 400, so that environmental lighting with different Z-axis height variations between the two flat luminaires can be provided. Figure 4 The embodiment shown in Fig. 4 is to combine the two luminaires 300 and 400 with single curved surfaces with each other to form a multi-curved light emitting effect. In other embodiments, the luminaires 300 and 400 can be directly replaced by a luminaire with a multi-curved surface, and the aforementioned purpose of adapting to different Z-axis height variations of environmental lighting can also be achieved.

[0045] Therefore, when it is necessary to change the installation position or lighting direction of the lamps, the desired lamp shape can be achieved by arranging and combining lamps 300 and 400 with general flat-panel lamps, so that they can be applied in various environments. For example... Figure 6 and Figure 7 As shown, Figure 6 and Figure 7 These are schematic diagrams illustrating a lighting system applicable to a stepped environment according to one embodiment of this disclosure. The lighting system 600 of this embodiment is mainly composed of luminaires 610, 300, 620, 400, 630, and 640 connected in series. Luminaires 610, 620, 630, and 640 are essentially the same flat-panel luminaire. Figure 6 and Figure 7 As shown, the concave lamp 300 and the convex lamp 400 can be used to change the extension direction between the flat lamps. For example, after the horizontally placed lamp 610 is installed, the first connector 351 of the lamp 300 can be connected to the lamp 610 in series, and the lamp 620 can be connected to the second connector 352 of the lamp 300 in series. Because the first connector 351 and the second connector 352 of the lamp 300 have different engagement directions, and combined with the concave arc design of the lamp 300, the lamp 620 can be tilted downward relative to the lamp 610. Similarly, if lamp 400 is then connected to lamp 620 and lamp 630 is then connected to lamp 400, because the first connector 451 and the second connector 452 of lamp 400 have different engagement directions, and combined with the concave arc design of lamp 400, lamp 630 can no longer be set at an angle like lamp 620, but can be set horizontally like lamp 610. This makes the overall lighting system 600 look like a stepped undulating appearance.

[0046] In one application example, the lighting system 600 can be used for lighting in environments with slopes or staircases ST. The number and arrangement of flat-panel luminaires (e.g., luminaires 610, 620, and 630) and curved-surface luminaires (e.g., luminaires 300 and 400) connected in series within the lighting system 600 can be determined according to the length of the staircase ST or the slope of the slope. In one embodiment, the apexes of several steps of the staircase ST can collectively form a connecting line L, and the direction of the series connection of the luminaires corresponds to the extension direction or slope of the connecting line L of the several step apexes, for example... Figure 7 The flat-panel luminaire 620 can be positioned parallel to the line L connecting the apexes of several steps, thereby enabling the luminaire system 600 to adapt to the height variations of slopes or stepped environments and to achieve better lighting effects.

[0047] Please also refer to Figure 8Fig. 7 is a schematic diagram showing a lamp system according to another embodiment of the present disclosure. In this embodiment, the lamp system 700 comprises a lamp 710, a lamp 720, and three lamps 300. The lamps 710 and 720 are flat lamps, and the lamps 300 are concave lamps. By connecting the lamps 300 in series between the lamps 710 and 720, the lamp system 700 forms a L-shaped appearance, which can be used in different occasions, such as exhibition halls. In other embodiments of the present disclosure, the curved surface of the lamp can be designed as a part of a circular arc, and the lamps can be connected to form a ring-shaped lamp.

[0048] As shown in the above embodiments of the present disclosure, the lamps of the present disclosure are integrated with the electrical connection assembly, the light source, and the light guide plate having a curved surface by the side cover, so that the lamps have simple structure and can be quickly assembled. The combination of the lamps and the flat lamps can form different lamp system appearances having different curvatures and different elevations.

[0049] Although the present disclosure has been disclosed by the above embodiments, the present disclosure is not intended to limit the embodiments of the present disclosure, and any person skilled in the art can make some changes and modifications without departing from the spirit and scope of the embodiments of the present disclosure. Therefore, the protection scope of the embodiments of the present disclosure should be subject to the protection scope of the appended claims.
