Description

Technical Field

[0001] This application relates to the field of lighting technology, and in particular to a linear luminaire. Background Technology

[0002] In practical applications, the installation location of the power supply and the wiring structure typically determine the installation location of the lighting fixtures. When the installation location of the lighting fixture does not correspond to the target lighting area, the wiring structure usually needs to be modified to change the installation location of the fixture to suit the target lighting area. However, this makes the installation process very complicated and hinders the ease of installation. Utility Model Content

[0003] The inventors of this application recognized that the light emission direction of traditional lamps is fixed. In practical applications, the installation location of the power supply and the wiring structure typically determine the installation location of the lamp. When the lamp's installation location does not correspond to the target lighting area, since the light emission direction is fixed, the wiring structure must be modified to change the lamp's installation location to match the target lighting area. However, this makes the installation process very complex, hindering ease of installation. The purpose of this invention is to provide a linear lamp that addresses the technical problem of poor installation convenience in existing linear lamps.

[0004] The basic concept proposed by the inventors of this application is that the light-emitting module and the housing are rotatably connected via a pivot. By rotating the light-emitting module, the light emission direction of the linear lamp can be adjusted. Thus, even when the installation position of the linear lamp does not correspond to the target lighting area, the light emission direction of the linear lamp can be adjusted by rotating the light-emitting module, allowing the light emitted by the light-emitting module to be projected onto the target lighting area. This achieves the adjustment of the installation position of the linear lamp without modifying the wiring structure, effectively simplifying the installation operation of the linear lamp and thus significantly improving its ease of installation.

[0005] This application provides a linear luminaire extending along its length. The linear luminaire includes a housing extending along its length, a rotating shaft arranged parallel to the length direction, and a light-emitting module extending along its length. The housing is used to house the light-emitting module, and the light-emitting module is rotatably connected to the housing via the rotating shaft to adjust the light emission direction of the linear luminaire.

[0006] The linear lighting device provided in this application embodiment has at least the following beneficial effects: The light-emitting module and the housing in the linear luminaire provided in this application embodiment are rotatably connected via a rotating shaft. By rotating the light-emitting module, the light emission direction of the linear luminaire can be adjusted. Thus, when the installation position of the linear luminaire does not correspond to the target lighting area, the light emission direction of the linear luminaire can be adjusted by rotating the light-emitting module, so that the light emitted by the light-emitting module can be projected into the target lighting area without modifying the wiring structure of the electrical circuit to adjust the installation position of the linear luminaire, effectively simplifying the installation operation of the linear luminaire and thus effectively improving the installation convenience of the linear luminaire.

[0007] In some embodiments of this application, the linear luminaire includes multiple rotating shafts and multiple light-emitting modules. The multiple light-emitting modules are rotatably connected to the housing via corresponding rotating shafts to adjust the light emission direction of the multiple light-emitting modules. The multiple light-emitting modules include a first light-emitting module and a second light-emitting module, which are arranged opposite to each other along the width direction of the housing.

[0008] By adopting the above technical solutions, not only can the illumination range of linear luminaires be increased, but the adjustment range of the light output direction of linear luminaires can also be increased, making linear luminaires suitable for more different installation scenarios and further improving the ease of installation of linear luminaires.

[0009] In some embodiments of this application, the plurality of light-emitting modules further includes a third light-emitting module, and the first light-emitting module and the second light-emitting module are both disposed opposite to the third light-emitting module along the height direction of the outer shell.

[0010] By adopting the above technical solution, not only can the linear luminaire emit light from both sides along the height direction, thus enriching the lighting effect of the linear luminaire, but the light emission direction of both sides along the height direction of the linear luminaire can also be adjusted separately, making the linear luminaire suitable for more different installation scenarios and further improving the ease of installation of the linear luminaire.

[0011] In some embodiments of this application, the plurality of light-emitting modules further includes a fourth light-emitting module. The first light-emitting module and the second light-emitting module are both disposed opposite to the fourth light-emitting module along the height direction of the housing, and the third light-emitting module and the fourth light-emitting module are disposed opposite to each other along the width direction of the housing.

[0012] By adopting the above technical solution, not only can the illumination range of the linear luminaire on both sides along the height direction be increased, but the adjustment range of the light output direction on both sides along the height direction can also be increased, making the linear luminaire suitable for more different installation scenarios and further improving the ease of installation of the linear luminaire.

[0013] In some embodiments of this application, the linear luminaire includes multiple rotating shafts and multiple light-emitting modules. The multiple light-emitting modules are rotatably connected to the housing via corresponding rotating shafts to adjust the light emission direction of the multiple light-emitting modules. The multiple light-emitting modules include a first light-emitting module and a third light-emitting module, which are arranged opposite to each other along the height direction of the housing.

[0014] By adopting the above technical solution, not only can the linear luminaire emit light from both sides along the height direction, thus enriching the lighting effect of the linear luminaire, but the light emission direction of both sides along the height direction of the linear luminaire can also be adjusted separately, making the linear luminaire suitable for more different installation scenarios and further improving the ease of installation of the linear luminaire.

[0015] In some embodiments of this application, the outer shell includes a housing, which has a first cavity, a second cavity, a first light-emitting port, and a second light-emitting port. The first cavity and the second cavity are separated from each other along the height direction of the housing. The first light-emitting port and the second light-emitting port are located on opposite sides of the housing along the height direction. The first light-emitting port communicates with the first cavity, and the second light-emitting port communicates with the second cavity. A first light-emitting module is housed in the first cavity, and a third light-emitting module is housed in the second cavity.

[0016] By adopting the above technical solution, the first light-emitting module and the third light-emitting module can be respectively set in two separate cavities, which effectively avoids light leakage between the first light-emitting module and the third light-emitting module and improves the lighting effect of the linear lamp.

[0017] In some embodiments of this application, the housing further includes a first light-transmitting plate and a second light-transmitting plate. The first light-transmitting plate covers the first light outlet to close the first cavity, and the second light-transmitting plate covers the second light outlet to close the second cavity.

[0018] By adopting the above technical solution, the first light-transmitting plate and the second light-transmitting plate can respectively seal the first cavity and the second cavity, effectively protecting the light-emitting module in the first cavity and the light-emitting module in the second cavity.

[0019] In some embodiments of this application, the rotating shaft includes a shaft portion and an operating portion. The shaft portion is connected to the light-emitting module and rotatably connected to the housing. The operating portion is connected to the shaft portion and disposed outside the housing.

[0020] By adopting the above technical solution, the operating part can be rotated outside the housing to drive the light-emitting module to rotate, thereby adjusting the light output direction of the linear lamp. The operation is simple and convenient.

[0021] In some embodiments of this application, the end face of the operating part near the light-emitting module and / or the end face of the light-emitting module near the operating part abuts against the wall surface of the housing.

[0022] By adopting the above technical solution, a certain damping can be generated between the light-emitting module and the housing, so that the light-emitting module can be relatively fixed with the housing after being rotated to the target angle, so that the light output direction of the adjusted light-emitting module remains unchanged, thereby improving the reliability of the linear lamp.

[0023] In some embodiments of this application, the light-emitting module has a connecting side and a light-emitting side on opposite sides, and the connecting side is rotatably connected to the housing via a rotating shaft.

[0024] By adopting the above technical solutions, the adjustment range of the light output direction of linear luminaires can be increased, making linear luminaires suitable for more different installation scenarios and further improving the ease of installation of linear luminaires.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] Please refer to the following: Figures 1 to 4 This application provides a linear luminaire 100 that extends along the length direction. The linear luminaire 100 includes a housing 10 extending along the length direction, a rotating shaft 20 arranged parallel to the length direction, and a light-emitting module 30 extending along the length direction. The housing 10 is used to accommodate the light-emitting module 30. The light-emitting module 30 is rotatably connected to the housing 10 via the rotating shaft 20 to adjust the light emission direction of the linear luminaire 100.

[0034] The housing 10 provides the internal environment of the linear luminaire 100 and defines the outer contour structure of the linear luminaire 100. The housing 10 has an elongated structure and has a length direction, a width direction, and a height direction, wherein the length direction of the housing 10 can be parallel to the width direction. Figures 1 to 3 The width direction of the outer casing 10 can be parallel to the X-axis shown. Figure 1 , Figure 2 and Figure 4 The direction parallel to the Y-axis shown can be the height direction of the outer casing 10. Figures 1 to 4 The directions parallel to the Z-axis shown are referred to as follows: the length direction of the outer shell 10 is called the length direction X, the width direction of the outer shell 10 is called the width direction Y, and the height direction of the outer shell 10 is called the height direction Z.

[0035] In some embodiments, the outer casing 10 includes a housing 11, which is the main body of the outer casing 10 and has an elongated structure. The housing 11 has a cavity for accommodating the light-emitting module 30. The housing 11 can be a one-piece molded component, for example, the housing 11 can be integrally molded using a casting process or an injection molding process. The housing 11 can also be formed by connecting multiple separately molded parts to form a whole. The material of the housing 11 can be, but is not limited to, aluminum, aluminum alloy, copper, stainless steel, plastic, etc.

[0036] The light-emitting module 30 is the core component of the linear luminaire 100, and it is used to output light. The light-emitting module 30 has a long strip structure and extends along the length direction X. There can be one or more light-emitting modules 30.

[0037] In some embodiments, please refer to the following: Figure 6 and Figure 7 The light-emitting module 30 includes a mounting base 33, a light source 34, a light guide 35, and a reflector 37. The mounting base 33 provides mounting space for the light source 34, the light guide 35, and the reflector 37. The mounting base 33 has an elongated structure and extends along its length direction X. As an example, the mounting base 33 has a slot 331 and a connecting slot 332 that connects to the slot 331. The light source 34 is fitted into the slot 331, and the light guide 35 and the reflector 37 are attached to each other and both inserted into the connecting slot 332. The light-emitting element of the light source 34 is positioned opposite the light guide 35.

[0038] As an example, the light-emitting module 30 also includes two second end caps 36, which are respectively covered at both ends of the mounting base 33. The second end caps 36 have limiting portions 361, which are used to abut against the side of the light guide 35 facing away from the light source 34, so as to restrict the light guide 35 within the insertion groove 332.

[0039] As an example, the light source 34 includes a circuit board and a plurality of light-emitting elements. The circuit board has an elongated structure and extends along the length direction X. The plurality of light-emitting elements are arranged on the circuit board with spacing between them along the length direction X. The light-emitting elements may be LED elements. The plurality of light-emitting elements may include a first group of light-emitting elements having at least a first color temperature and a second group of light-emitting elements having at least a second color temperature, so as to achieve adjustable color temperature of the linear luminaire 100.

[0040] As an example, the light guide 35 has an elongated structure and extends along its length direction X. The light guide 35 includes a first total internal reflection surface 351, a second total internal reflection surface 352, a first side surface 353, and a second side surface 354. The first side surface 353 and the second side surface 354 are arranged opposite to each other and extend between the first total internal reflection surface 351 and the second total internal reflection surface 352, respectively. The first side surface 353 is the light incident surface of the light guide 35, and the second side surface 354 is the light emitting surface of the light guide 35. The light-emitting element is positioned opposite the first side surface 353 and configured to emit light toward the first side surface 353, while the light is emitted outward from the second side surface 354.

[0041] As an example, the reflector 37 has an elongated structure and extends along its length direction X. The reflector 37 is attached to the first total internal reflection surface 351 of the light guide 35, and at least a portion of the reflector 37 extends from the second side surface 354 in a direction away from the light guide 35. The reflector 37 includes a reflective surface disposed facing the first total internal reflection surface 351. In this way, light emitted from the light guide 35 is reflected by the reflector 37 to illuminate the target illumination area facing the second total internal reflection surface 352. Simultaneously, if light emitted from the light source 34 is incident on the first total internal reflection surface 351 at an angle smaller than the critical angle of the light guide 35, the light is reflected back to the light guide 35 by the reflector 37. The light output from the linear luminaire 100 is a combination of the light guided by the light guide 35 through the first and second total internal reflection surfaces 351 and the light reflected by the reflector 37.

[0042] As an example, both the first total internal reflection surface 351 and the second total internal reflection surface 352 are smooth surfaces or mirror surfaces, and neither the first total internal reflection surface 351 nor the second total internal reflection surface 352 has any light extraction structure. In this way, the light emitted by the light source 34 and output from the second side 354 can illuminate the expected distance, improving the illumination range of the linear luminaire 100 and making the illumination effect of the linear luminaire 100 more uniform.

[0043] The pivot 20 is a component used to connect the light-emitting module 30 and the housing 10, so that the light-emitting module 30 can rotate around the pivot 20. Understandably, the central axis of the pivot 20 is set parallel to the length direction X.

[0044] In some embodiments, please refer to the following: Figure 2 and Figure 5 The rotating shaft 20 includes a first shaft 21 and a second shaft 22. The first shaft 21 and the second shaft 22 are coaxially arranged. The first shaft 21 is used to connect one end of the housing 10 along the length direction X to one end of the light-emitting module 30 along the length direction X, and the second shaft 22 is used to connect the other end of the housing 10 along the length direction X to the other end of the light-emitting module 30 along the length direction X, so that the light-emitting module 30 can rotate around the rotating shaft 20.

[0045] As an example, the housing 10 also includes two first end caps 14, which are respectively covered at both ends of the housing 11 along the length direction X. A first shaft 21 is used to connect one first end cap 14 to one end of the light-emitting module 30 along the length direction X, and a second shaft 22 is used to connect the other first end cap 14 to the other end of the light-emitting module 30 along the length direction X, so that the light-emitting module 30 can rotate around the rotating shaft 20.

[0046] In some embodiments, the linear luminaire 100 may further include a suspension member 40, which suspends the linear luminaire 100 on the target installation area.

[0047] Understandably, the linear luminaire 100 described above can be applied to any application scenario. The working principle of the linear luminaire 100 will be explained below with reference to one application scenario.

[0048] Please see Figure 8 The linear luminaire 100 is installed on the ceiling 400, and the table 200 is attached to the wall 300. The target lighting area of ​​the linear luminaire 100 is the tabletop of the table 200, but the installation position of the linear luminaire 100 is off from the position of the table 200. At this time, the light emission direction of the linear luminaire 100 can be changed by rotating the light-emitting module 30, so that the light emitted by the light-emitting module 30 can illuminate the tabletop of the table 200.

[0049] The light-emitting module 30 of the linear luminaire 100 provided in this application embodiment is rotatably connected to the housing 10 via a pivot 20. By rotating the light-emitting module 30, the light emission direction of the linear luminaire 100 can be adjusted. Thus, when the installation position of the linear luminaire 100 does not correspond to the target lighting area, the light emission direction of the linear luminaire 100 can be adjusted by rotating the light-emitting module 30, so that the light emitted by the light-emitting module 30 can be projected into the target lighting area without modifying the wiring structure of the electrical circuit. This effectively simplifies the installation operation of the linear luminaire 100 and improves the ease of installation.

[0050] In some embodiments of this application, please refer to Figure 4 The linear luminaire 100 includes multiple rotating shafts 20 and multiple light-emitting modules 30. The multiple light-emitting modules 30 are rotatably connected to the housing 10 through corresponding rotating shafts 20 to adjust the light emission direction of the multiple light-emitting modules 30. The multiple light-emitting modules 30 include a first light-emitting module 30a and a second light-emitting module 30b. The first light-emitting module 30a and the second light-emitting module 30b are arranged opposite to each other along the width direction Y of the housing 10.

[0051] In some embodiments, along the width direction Y of the housing 10, the second total internal reflection surface 352 of the first light-emitting module 30a and the second total internal reflection surface 352 of the second light-emitting module 30b are disposed opposite to each other, and the first total internal reflection surface 351 of the first light-emitting module 30a and the first total internal reflection surface 351 of the second light-emitting module 30b are disposed opposite to each other.

[0052] In other embodiments, along the width direction Y of the housing 10, the first total internal reflection surface 351 of the first light-emitting module 30a and the first total internal reflection surface 351 of the second light-emitting module 30b are disposed opposite to each other, and the second total internal reflection surface 352 of the first light-emitting module 30a and the second total internal reflection surface 352 of the second light-emitting module 30b are disposed opposite to each other.

[0053] By adopting the above technical solution, not only can the illumination range of the linear luminaire 100 be increased, but the adjustment range of the light output direction of the linear luminaire 100 can also be increased, making the linear luminaire 100 applicable to more different installation scenarios and further improving the ease of installation of the linear luminaire 100.

[0054] In some embodiments of this application, please refer to Figure 4 The plurality of light-emitting modules 30 also includes a third light-emitting module 30c. The first light-emitting module 30a and the second light-emitting module 30b are both arranged opposite to the third light-emitting module 30c along the height direction Z of the outer shell 10.

[0055] By adopting the above technical solution, not only can the linear luminaire 100 emit light from both sides along the height direction Z, thus enriching the lighting effect of the linear luminaire 100, but the light emission direction of the linear luminaire 100 on both sides along the height direction Z can also be adjusted separately, making the linear luminaire 100 suitable for more different installation scenarios and further improving the ease of installation of the linear luminaire 100.

[0056] In some embodiments of this application, please refer to Figure 4 The plurality of light-emitting modules 30 also includes a fourth light-emitting module 30d. The first light-emitting module 30a and the second light-emitting module 30b are both arranged opposite to the fourth light-emitting module 30d along the height direction Z of the outer shell 10. The third light-emitting module 30c is arranged opposite to the fourth light-emitting module 30d along the width direction Y of the outer shell 10.

[0057] In some embodiments, along the width direction Y of the housing 10, the second total internal reflection surface 352 of the third light-emitting module 30c is disposed opposite to the second total internal reflection surface 352 of the fourth light-emitting module 30d, and the first total internal reflection surface 351 of the third light-emitting module 30c is disposed opposite to the first total internal reflection surface 351 of the fourth light-emitting module 30d.

[0058] In other embodiments, along the width direction Y of the housing 10, the first total internal reflection surface 351 of the third light-emitting module 30c is disposed opposite to the first total internal reflection surface 351 of the fourth light-emitting module 30d, and the second total internal reflection surface 352 of the third light-emitting module 30c is disposed opposite to the second total internal reflection surface 352 of the fourth light-emitting module 30d.

[0059] Please see Figure 8 A linear light fixture 100 is installed on the ceiling 400. The light emitted by the first light-emitting module 30a and the light emitted by the second light-emitting module 30b combine to form a first light-emitting area 101. The light from the first light-emitting area 101 illuminates the tabletop of the table 200. The light emitted by the third light-emitting module 30c and the light emitted by the fourth light-emitting module 30d combine to form a second light-emitting area 102. The light from the second light-emitting area 102 illuminates the ceiling 400.

[0060] By adopting the above technical solution, not only can the illumination range of the linear luminaire 100 on both sides along the height direction Z be increased, but the adjustment range of the light output direction on both sides along the height direction Z of the linear luminaire 100 can also be increased, making the linear luminaire 100 applicable to more different installation scenarios and further improving the ease of installation of the linear luminaire 100.

[0061] In some embodiments of this application, please refer to Figure 4 The linear luminaire 100 includes multiple rotating shafts 20 and multiple light-emitting modules 30. The multiple light-emitting modules 30 are rotatably connected to the housing 10 through corresponding rotating shafts 20 to adjust the light emission direction of the multiple light-emitting modules 30. The multiple light-emitting modules 30 include a first light-emitting module 30a and a third light-emitting module 30c. The first light-emitting module 30a and the third light-emitting module 30c are arranged opposite to each other along the height direction Z of the housing 10.

[0062] By adopting the above technical solution, not only can the linear luminaire 100 emit light from both sides along the height direction Z, thus enriching the lighting effect of the linear luminaire 100, but the light emission direction of the linear luminaire 100 on both sides along the height direction Z can also be adjusted separately, making the linear luminaire 100 suitable for more different installation scenarios and further improving the ease of installation of the linear luminaire 100.

[0063] Please refer to some embodiments of this application as well. Figure 2 and Figure 4The housing 11 has a first cavity 111, a second cavity 112, a first light-emitting port 113, and a second light-emitting port 114. The first cavity 111 and the second cavity 112 are separated from each other along the height direction Z of the housing 11. The first light-emitting port 113 and the second light-emitting port 114 are respectively located on opposite sides of the housing 11 along the height direction Z. The first light-emitting port 113 is connected to the first cavity 111, and the second light-emitting port 114 is connected to the second cavity 112. The first light-emitting module 30a is housed in the first cavity 111, and the third light-emitting module 30c is housed in the second cavity 112.

[0064] In some embodiments, the plurality of light-emitting modules 30 further include a first light-emitting module 30a, a second light-emitting module 30b, a third light-emitting module 30c, and a fourth light-emitting module 30d.

[0065] In some embodiments, please refer to Figure 4 The housing 11 has an X-shaped structure. As an example, the housing 11 includes a first plate 115, a second plate 116, a third plate 117, a fourth plate 118, and a partition 119. The first plate 115 and the second plate 116 are both connected to one side of the partition 119 along the width direction Y, and the third plate 117 and the fourth plate 118 are both connected to the other side of the partition 119 along the width direction Y. The first plate 115 and the third plate 117 both extend from one side of the partition 119 along the height direction Z in a direction away from the partition 119, and the first plate 115 and the third plate 117... The spacing between the plates gradually increases in the direction away from the partition 119 to form a first flare. The second plate 116 and the fourth plate 118 both extend from the partition 119 along the height direction Z in the direction away from the partition 119, and the spacing between the second plate 116 and the fourth plate 118 gradually increases in the direction away from the partition 119 to form a second flare. The first plate 115, the third plate 117 and the partition 119 define a first cavity 111. The second plate 116, the fourth plate 118 and the partition 119 define the first cavity 111.

[0066] By adopting the above technical solution, the first light-emitting module 30a and the third light-emitting module 30c can be respectively placed in two mutually separated cavities, effectively avoiding light leakage between the first light-emitting module 30a and the third light-emitting module 30c, and improving the lighting effect of the linear lamp 100.

[0067] Please refer to some embodiments of this application as well. Figure 2 and Figure 4 The outer casing 10 also includes a first light-transmitting plate 12 and a second light-transmitting plate 13. The first light-transmitting plate 12 covers the first light outlet 113 to close the first cavity 111, and the second light-transmitting plate 13 covers the second light outlet 114 to close the second cavity 112.

[0068] In some embodiments, the plurality of light-emitting modules 30 further include a first light-emitting module 30a, a second light-emitting module 30b, a third light-emitting module 30c, and a fourth light-emitting module 30d.

[0069] In some embodiments, please refer to Figure 4 The housing 11 has an X-shaped structure. As an example, the housing 11 includes a first plate 115, a second plate 116, a third plate 117, a fourth plate 118, and a partition 119. The first plate 115 and the second plate 116 are both connected to one side of the partition 119 along the width direction Y, and the third plate 117 and the fourth plate 118 are both connected to the other side of the partition 119 along the width direction Y. The first plate 115 and the third plate 117 both extend from one side of the partition 119 along the height direction Z in a direction away from the partition 119, and the first plate 115 and the third plate 117... The spacing between the plates gradually increases in the direction away from the partition 119 to form a first flare. The second plate 116 and the fourth plate 118 both extend from the partition 119 along the height direction Z in the direction away from the partition 119, and the spacing between the second plate 116 and the fourth plate 118 gradually increases in the direction away from the partition 119 to form a second flare.

The first light-transmitting plate 12 is disposed between the first plate 115 and the third plate 117, and the second light-transmitting plate 13 is disposed between the second plate 116 and the fourth plate 118.

[0070] By adopting the above technical solution, the first light-transmitting plate 12 and the second light-transmitting plate 13 can respectively seal the first cavity 111 and the second cavity 112, effectively protecting the light-emitting module 30 in the first cavity 111 and the light-emitting module 30 in the second cavity 112.

[0071] In some embodiments of this application, please refer to Figure 5 The rotating shaft 20 includes a shaft portion 23 and an operating portion 24. The shaft portion 23 is connected to the light-emitting module 30 and rotatably connected to the housing 10. The operating portion 24 is connected to the shaft portion 23 and is disposed outside the housing 10.

[0072] In some embodiments, please refer to the following: Figure 2 and Figure 5 The rotating shaft 20 includes a first shaft 21 and a second shaft 22, which are coaxially arranged. The first shaft 21 connects one end of the housing 10 along the length direction X to one end of the light-emitting module 30 along the length direction X, and the second shaft 22 connects the other end of the housing 10 along the length direction X to the other end of the light-emitting module 30 along the length direction X, so that the light-emitting module 30 can rotate around the rotating shaft 20. At least one of the first shaft 21 and the second shaft 22 includes a shaft portion 23 and an operating portion 24. As an example, both the first shaft 21 and the second shaft 22 include a shaft portion 23 and an operating portion 24.

[0073] In some embodiments, the outer peripheral surface of the operating part 24 is non-planar. For example, multiple protrusions or multiple recesses are evenly distributed on the outer peripheral surface of the operating part 24 to increase the friction coefficient of the outer peripheral surface of the operating part 24, thereby making it easier to rotate the operating part 24.

[0074] By adopting the above technical solution, the operating part 24 can be rotated outside the housing 10 to drive the light-emitting module 30 to rotate, thereby realizing the adjustment of the light emission direction of the linear lamp 100, which is simple and convenient to operate.

[0075] In some embodiments of this application, the end face of the operating part 24 near the light-emitting module 30 and / or the end face of the light-emitting module 30 near the operating part 24 abuts against the wall surface of the housing 10.

[0076] In some embodiments, the end face of the operating part 24 near the light-emitting module 30 and / or the end face of the light-emitting module 30 near the operating part 24 abuts against the first end cap 14.

[0077] As an example, the end face of the operating part 24 near the light-emitting module 30 is attached to the first end cover 14.

[0078] As an example, the end face of the light-emitting module 30 near the operation part 24 is attached to the first end cover 14.

[0079] The end face of the operating part 24 near the light-emitting module 30 and the end face of the light-emitting module 30 near the operating part 24 are both attached to the first end cover 14.

[0080] By adopting the above technical solution, a certain damping can be generated between the light-emitting module 30 and the housing 10, so that after the light-emitting module 30 is rotated to the target angle, the light-emitting module 30 can be fixed relative to the housing 10, so that the light-emitting direction of the adjusted light-emitting module 30 remains unchanged, thereby improving the reliability of the linear lamp 100.

[0081] Please refer to some embodiments of this application as well. Figure 4 and Figure 7 The light-emitting module 30 has a connecting side 31 and a light-emitting side 32 on opposite sides. The connecting side 31 is rotatably connected to the outer shell 10 via a rotating shaft 20.

[0082] In some embodiments, please refer to Figure 7 The light-emitting module 30 includes a mounting base 33, a light source 34, a light guide 35, and a reflector 37. The side of the mounting base 33 away from the second side 354 of the light guide 35 constitutes the aforementioned connecting side 31, and the side of the mounting base 33 close to the second side 354 of the light guide 35 constitutes the aforementioned light-emitting side 32.

[0083] As an example, the mounting base 33 has a slot on the connecting side 31, and the rotating shaft 20 is inserted into the slot and pressurized against the slot wall so that the rotating shaft 20 is fixed relative to the mounting base 33.

[0084] By adopting the above technical solution, the adjustment range of the light output direction of the linear luminaire 100 can be increased, making the linear luminaire 100 applicable to more different installation scenarios and further improving the ease of installation of the linear luminaire 100.

[0085] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
