Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a lamp with an adjustable light output pattern. Background Technology

[0002] Wall lamps are commonly seen on walls along streets, in gardens, and in courtyards, used for lighting and creating ambiance. A wall lamp generally consists of a mounting bracket and a lamp body. The mounting bracket is typically installed perpendicular to the wall, and the lamp body is mounted on the bracket, allowing the light to shine either upwards or downwards. For better lighting effects, the lamp head can be designed as a double-headed lamp, with one head shining upwards and the other downwards. To achieve a more ambiance, the lamp body can be designed with multiple color temperatures and wattage levels, allowing for different levels of color temperature and brightness.

[0003] To further enhance the ambiance, the wall lamp can also adjust its light pattern. Current technology typically achieves this by replacing the light-emitting shield on the light source side; however, replacing the shield is currently quite complex, and the shield itself is large, resulting in high costs. Utility Model Content

[0004] The main purpose of this utility model is to propose a lamp with a changeable light output pattern, which aims to solve the problems of complicated operation and high replacement cost of light shields when replacing them.

[0005] To achieve the above objectives, this utility model proposes a lamp with a changeable light emission pattern, comprising a housing, a light source module, a cover plate, and a light shield. The housing has an accommodating space with a light emission port; the light source module is disposed within the accommodating space, and the light emitted from it is emitted through the light emission port; the cover plate covers the light emission port and is rotatably connected to the housing, and the cover plate can be opened or closed relative to the light emission port; the light shield covers the light emission port and is located on the side of the cover plate closer to the light source module, and the light shield has different shapes and / or different numbers of light-transmitting holes.

[0006] In the lamps of this application embodiment, the light emitted by the light source module can pass through the light-transmitting holes on the light shield to illuminate different shapes of light patterns, thereby enhancing the ambient effect of the lamps. When it is necessary to adjust the light pattern, it is only necessary to open the cover plate provided at the light outlet and replace the light shield with a light-transmitting hole of a different shape and number. The replacement operation is simple and convenient. At the same time, since the thickness and volume of the light shield are small, the manufacturing and drilling costs of the light shield are low, thereby effectively reducing the replacement cost of the light shield.

[0023] Please see Figures 1-4 This application proposes a lamp 100 with a changeable light emission pattern. The lamp 100 includes a housing 10, a light source module 20, a cover plate 30, and a light shield 40. The housing 10 has an accommodating space 11 with a light emission port 12. The light source module 20 is disposed in the accommodating space 11 and the light emitted by it is emitted from the light emission port 12. The cover plate 30 is disposed on the light emission port 12 and is rotatably connected to the housing 10. The cover plate 30 can be opened or closed relative to the light emission port 12. The light shield 40 is disposed on the light emission port 12 and is located on the side of the cover plate 30 closer to the light source module 20. The light shield 40 has different shapes and / or different numbers of light-transmitting holes 41.

[0024] In the lamp 100 of this application embodiment, the light emitted by the light source module 20 can pass through the light-transmitting holes 41 on the light shield 40 to illuminate different light patterns, thereby enhancing the ambient effect of the lamp 100. When it is necessary to adjust the light pattern, it is only necessary to open the cover plate 30 provided at the light outlet 12 and replace the light shield 40 with different shapes and numbers of light-transmitting holes 41. The replacement operation is simple and convenient. At the same time, since the thickness and volume of the light shield 40 are small, the cost of the light shield 40 is low, thereby effectively reducing the replacement cost of the light shield 40.

[0025] Specifically, such as Figure 1As shown, the housing 10 can be a rectangular cube structure with a hollow internal space 11, where the light source module 20 and multiple control modules can be installed. The housing 10 can be made of rigid materials such as metal or plastic, thus providing good protection for the internal modules. Of course, the housing 10 can also have other shapes, such as a polygonal prism structure or a polyhedral structure. This application does not impose specific limitations on the shape and material of the housing 10.

[0026] The housing 10 is also provided with light emission ports 12. The number of light emission ports 12 can be one or more, depending on the actual needs. In this embodiment, two light emission ports 12 are used as an example. The two light emission ports 12 are respectively opened at the top and bottom of the housing 10. Correspondingly, the light source module 20 is installed in the accommodating space 11 at the position corresponding to the light emission port 12. The light emitted by the light source module 20 can be emitted upward from the light emission port 12 at the top of the housing 10 and downward from the light emission port 12 at the bottom of the housing 10.

[0027] The light source module 20 may include a lamp board and LEDs mounted on the lamp board. The LEDs are electrically connected to the lamp board and can emit light of different intensities and color temperatures under the control of the lamp board, so that the lamp 100 can provide lighting with different atmosphere effects.

[0028] To further enhance the ambiance of the luminaire 100, a cover plate 30 and a light-shielding plate 40 can be provided at the light outlet 12 of the luminaire 100. The light-shielding plate 40 can be made of an opaque material and has a sheet-like structure, such as... Figure 4 As shown, the light-shielding plate 40 can be provided with light-transmitting holes 41 of different shapes and numbers. The light-shielding plate 40 is placed over the light-emitting port 12, and the light emitted by the light source module 20 can pass through the light-transmitting holes 41 and be emitted. Under the protection of the light-shielding plate 40, the light source module 20 can emit different shapes of light patterns according to the different shapes of the light-transmitting holes 41, so as to enhance the atmosphere.

[0029] The cover plate 30 can be made of a light-transmitting material and has a plate-like structure. The cover plate 30 is placed over the light outlet 12. The light emitted by the light source module 20 passes through the light-transmitting hole 41 and can be emitted through the cover plate 30. The transparent cover plate 30 will not affect the light emission pattern. Preferably, the cover plate 30 can be located on the side opposite to the light-shielding plate 40, so that the cover plate 30 covers the light outlet 12 and also covers the light-shielding plate 40. The cover plate 30 not only plays a role in light transmission, but also plays a certain protective role, preventing damage to the light-shielding plate 40 and preventing dust and debris from entering the receiving space 11 through the light outlet 12.

[0030] The light-shielding sheet 40 can be made of opaque paper, plastic sheet, or iron sheet, and its thickness can range from 0.5mm to 5mm, for example, 0.5mm, 1mm, 3mm, or 5mm. Because the light-shielding sheet 40 is relatively thin, it is easier to create the light-transmitting hole 41, resulting in lower manufacturing costs. Consequently, the cost of replacing the light-shielding sheet 40 is also lower when the light emission pattern needs to be changed. Compared to the prior art where each light-shielding component requires mold making and hole punching processes, the replaceable light-shielding sheet 40 on the lamp 100 in this embodiment effectively reduces costs.

[0031] In addition, to facilitate the replacement of the light-shielding sheet 40 inside the cover plate 30, one side edge of the cover plate 30 is rotatably connected to the housing 10. That is to say, the cover plate 30 can be opened or closed relative to the light outlet 12. Thus, when it is necessary to replace the light-shielding sheet 40 to adjust the light output pattern, the cover plate 30 can be opened relative to the light outlet 12 to replace the light-shielding sheet 40. The replacement process is simple and convenient.

[0032] Please see Figure 2 and Figure 5 In some embodiments, the luminaire 100 further includes a protective cover 50, which is positioned over the light outlet 12. The protective cover 50 is located on the side of the cover plate 30 closest to the light source module 20, and the light-shielding sheet 40 is located between the cover plate 30 and the protective cover 50. In this way, the protective cover 50 can further protect the multiple modules within the housing space 11, preventing damage to the modules within the housing space 11 and preventing dust, rainwater, and other debris from entering the housing space 11.

[0033] Specifically, the protective cover 50 can be made of a light-transmitting material, allowing light emitted from the light source module 20 to pass through it. The protective cover 50 completely covers the light outlet 12, thus preventing debris and rainwater from entering the receiving space 11. The light-shielding plate 40 and the light-blocking plate are both located on the outside of the protective cover 50 relative to the light source module 20, ensuring that the protective cover 50 does not interfere with the replacement of the light-shielding plate 40.

[0034] Please see Figure 5 and Figure 6 In some embodiments, a water-retaining wall 13 is provided around the light-emitting port 12, and a mounting groove 51 is provided around the protective cover 50. The opening of the mounting groove 51 faces the water-retaining wall 13. The protective cover 50 is installed by cooperating with the water-retaining wall 13 through the mounting groove 51, and a sealing strip 52 is provided between the mounting groove 51 and the water-retaining wall 13. In this way, the protective cover 50 can completely seal the light-emitting port 12 through the water-retaining wall 13 and the sealing strip 52. When the lamp 100 is installed in the external environment, no debris or rainwater will enter the housing space 11, thereby better protecting the multiple modules in the housing space 11.

[0035] Specifically, the water-blocking wall 13 can protrude from the outer periphery of the light outlet 12 in the light-emitting direction. Correspondingly, the outer periphery of the protective cover 50 has a mounting groove 51 facing the water-blocking wall 13, with the opening of the mounting groove 51 facing the water-blocking wall 13. When the protective cover 50 is installed at the light outlet 12, the water-blocking wall 13 can extend into the mounting groove 51. This design of the installation method between the protective cover 50 and the housing 10 can better achieve the waterproof function.

[0036] like Figure 6 As shown, in order to further seal the installation of the protective cover 50, a "U"-shaped sealing strip 52 can be fitted on the water-blocking wall 13, and then the protective cover 50 can be fastened on the outside of the sealing strip 52. In this way, with the further sealing of the sealing strip 52, the installation of the protective cover 50 is more tight and can better block the entry of rainwater.

[0037] In some embodiments, the light-shielding plate 40 can be fixed to the side of the cover plate 30 near the light source module 20 by magnetic attraction, adhesion, snap-fit, etc., and the light-shielding plate 40 can rotate together with the cover plate 30. Of course, the light-shielding plate 40 can also be fixed to the housing 10 on the edge of the light outlet 12 by its edge. The installation method of the light-shielding plate 40 is not limited in the embodiments of this application.

[0038] Please see Figure 3 and Figure 8 In some embodiments, the light-shielding sheet 40 can be installed on the cover plate 30 by insertion. A slot 31 is formed on the side of the cover plate 30 near the light source module 20. The slot 31 can be surrounded by a limiting strip 311, which can be L-shaped and extend along the edge of the cover plate 30. One end of the limiting strip is connected to the cover plate 30, and the other end is used to fix the light-shielding sheet 40. The limiting strip 311 can be located on three sides of the cover plate 30, with at least one side open, serving as an insertion port 312. The light-shielding sheet 40 can then be inserted into the slot 31 through the insertion port 312. Thus, when the light-shielding sheet 40 needs to be replaced, simply open the cover plate 30, remove the light-shielding sheet 40 from the slot 31, and then reinsert the replacement light-shielding sheet 40 into the slot 31. The replacement method is simple and convenient.

[0039] Specifically, the slot 31 can be located at the edge of the cover plate 30 near the light source module 20. The slot 31 extends along the edge of the cover plate 30, so that when the light-shielding sheet 40 is inserted into the slot 31, the slot 31 will not affect the light output of the light source module 20. Figure 7 and Figure 8As shown, the plane of the slot 31 is parallel to the surface of the cover plate 30, allowing the light emitted from the light source module 20 to pass through the light-transmitting hole 41 more effectively. The slot 31 has a socket 312 on at least one side, through which the light-shielding sheet 40 can be inserted for installation. The socket 312 can be located on the side of the cover plate 30 opposite to the pivot 32, or it can be located on both sides of the cover plate 30, as long as the light-shielding sheet 40 can be easily inserted into the slot 31.

[0040] Please see Figure 2 and Figure 3 In some embodiments, a rotating shaft 32 is provided at both ends of one side edge of the cover plate 30. The rotating shaft 32 protrudes to both ends along the extension direction of the side edge. A shaft hole 14 is provided at both ends of one side edge of the light outlet 12. The rotating shaft 32 and the shaft hole 14 are rotatably connected.

[0041] Thus, the cover plate 30 can be rotatably connected to the corresponding shaft hole 14 on the housing 10 through the rotating shaft 32 on both sides, so that the cover plate 30 can be opened or closed relative to the light outlet 12 with the rotating shaft 32 as the axis, so as to facilitate the replacement of the light shield 40.

[0042] Specifically, the rotating shaft 32 can be cylindrical, extending a certain length from one side edge of the cover plate 30 to both ends. The cylindrical rotating shaft 32 facilitates the rotation of the cover plate 30. Correspondingly, the shaft hole 14 can be opened at both ends of one side edge of the light outlet 12, and the rotating shafts 32 on both sides of the cover plate 30 can be inserted into the shaft hole 14.

[0043] Since one side of the cover plate 30 is rotatably connected to the housing 10 via the pivot 32, while the other side is free to rotate relative to the housing 10, the other side of the cover plate 30 needs to be fixed to ensure the stability of the cover plate 30 during normal use of the lamp 100, preventing the cover plate 30 from flipping over arbitrarily. In some embodiments, the side of the cover plate 30 away from the pivot 32 is provided with a through hole 33, and the housing 10 is provided with a screw hole 34. The through hole 33 and the screw hole 34 correspond to each other, and the screw 35 passes through the through hole 33 and the screw hole 34 in sequence. The cover plate 30 is fixed by the screw 35 threaded into the screw hole 34. In this way, the side of the cover plate 30 away from the pivot 32 can be closed and fixed relative to the light outlet 12 by the screw 35, so that the cover plate 30 can be stably fixed at the light outlet 12.

[0044] In some embodiments, the screw hole 34 may also be provided on the protective cover 50. However, the screw hole 34 provided on the protective cover 50 is not a through hole, thereby preventing rainwater from entering the receiving space 11 when the cover 30 is opened. The opening of the screw hole 34 faces the side of the cover 30 and corresponds to the through hole 33 on the cover 30. The screw 35 passes through the through hole 33 on the cover 30 and is threaded into the screw hole 34.

[0045] Of course, in some other embodiments, the free side of the cover plate 30 can also be connected to the housing 10 by means of snap-fit, fastening, magnetic attraction, etc. This application does not limit the connection method between the right side of the cover plate 30 and the housing 10.

[0046] Please see Figure 5 In some embodiments, a fixing plate 60 is provided inside the accommodating space 11. The fixing plate 60 includes a supporting part 61, a reflective part 62 and a connecting part 63. The light source module 20 is disposed on the supporting part 61. The reflective part 62 extends obliquely along the periphery of the supporting part 61 toward the light outlet 12. One end of the connecting part 63 is connected to the reflective part 62, and the other end is connected to the inner wall of the accommodating space 11.

[0047] Thus, the light source module 20 can be fixed in the accommodating space 11 by the fixing plate 60, the bearing part 61 can stably fix the light source module 20, the reflector part 62 can gather the light emitted by the light source module 20 toward the light outlet 12 to prevent the light from scattering, and the connecting part 63 plays a fixing role.

[0048] Specifically, the fixing plate 60 can be disposed inside the receiving space 11. The supporting part 61 can be disposed facing the light outlet 12, and the light source module 20 is fixedly mounted on the supporting part 61 and can irradiate light in the direction of the light outlet 12. The reflective part 62 extends obliquely from the edge of the supporting part 61 towards the light outlet 12, and the inner wall of the reflective part 62 can reflect at least part of the light. The connecting wall extends along the reflective part 62 towards the inner wall of the receiving space 11 and connects with the inner wall of the receiving space 11. The fixing plate 60 can be installed inside the receiving space 11 through the connecting part 63.

[0049] In some other embodiments, the fixing plate 60 can also be slidably disposed within the receiving space 11. For example, the fixing plate 60 can move up and down along the direction of approaching or moving away from the protective cover 50, thereby driving the light source module 20 to move, so that the light emitted by the light source module 20 has different light emission effects after passing through the light emission port 12, thereby improving the light emission mode of the lamp 100.

[0050] Please see Figure 2 and Figure 7 In some embodiments, the luminaire 100 further includes a back plate 70, the edge of which is provided with a connecting wall facing the housing 10; when the back plate 70 is fixed to a wall, the housing 10 is engaged with the connecting wall to fix the luminaire 100 to the back plate 70. In this way, the luminaire 100 can be installed and fixed through the back plate 70, and the installation method is simple and convenient.

[0051] Specifically, when the lamp 100 needs to be installed in a designated location, the back plate 70 can be fixed in that location first, and then the lamp 100 can be connected to the back plate 70. The connection method is simple and convenient. At the same time, when the lamp 100 is disassembled, the back plate 70 can be installed on the back of the lamp 100, resulting in a small storage volume and easy movement and transportation.

[0052] In some embodiments, the luminaire 100 further includes a control module disposed within the receiving space 11. The control module includes a switch module, a power adjustment module, a color temperature control module, and a sensing module. The light source module 20 is electrically connected to the control module. Thus, the light source module 20 can be controlled through the control module to adjust the light output effect of the light source module 20 and enhance the ambient effect of the luminaire 100.

[0053] Specifically, the switch module can be used to control the opening and closing of the light source module 20, the power adjustment module can be used to adjust the light output power of the light source module 20, the color temperature control module can be used to adjust the color temperature of the light emitted by the light source module 20, and the sensing module can be used to sense moving objects near the lamp 100.

[0054] The lamp 100 may include one or more of the aforementioned modules. Of course, the lamp 100 may also include other functional modules. This application does not limit the type of module for the control module, as long as it can control the light output effect of the light source module 20 to achieve lighting and ambiance effects.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
