Description

Technical Field

[0001] The present invention belongs to the technical field of lamps, and in particular relates to a lampshade and a lamp. Background Art

[0002] In related art, a lamp consists of a housing, a light panel, and a lens. The light panel is located within the housing, and the lens is positioned on the side of the light panel that houses the lamp beads. The lens surface is typically provided with microstructures that effectively reduce glare as the light passes through it. However, the glare reduction effect of the lens is limited. Therefore, if the light emitted by the lamp still has a strong glare effect, it can easily cause discomfort to the user. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a lampshade and a lamp that can effectively reduce the glare effect of the illumination light emitted from the lamp.

[0004] In order to achieve the above-mentioned purpose, the present invention discloses a lampshade, which is made of a transparent material, and includes an inner cover part and an outer cover part. The inner cover part is provided with a first light port and a second light port. From the first light port to the second light port, the cross-section of the inner cover part is gradually expanded. The outer cover part is located on the outside of the inner cover part, one end of the outer cover part is connected to the second light port, and the other end of the outer cover part is spaced apart from the inner cover part; wherein, along the circumferential direction of the inner cover part, the inner side of the inner cover part is sequentially provided with ridges, and each of the ridges extends from the first light port to the second light port.

[0005] As an optional embodiment, the ridges are configured to make the incident angle of light entering the inner cover portion greater than or equal to the critical angle of the inner cover portion.

[0006] As an optional embodiment, the outer surface of the inner cover portion is smooth.

[0007] As an optional implementation manner, the cross section of the ridge is gradually enlarged from the first optical port to the second optical port.

[0008] As an optional embodiment, the cross section of the ridge is triangular, or the cross section of the ridge is arc-shaped and convex.

[0009] As an optional embodiment, the side edges of adjacent ridges are connected to form reflective grooves between the adjacent ridges.

[0010] The present invention also discloses a lamp, comprising:

[0011] The housing is provided with a first light outlet, and the inner wall of the housing is provided with a locking boss;

[0012] a first light panel, disposed on the inner side of the housing;

[0013] The above-mentioned lampshade has a first elastic arm on both sides of the bottom of the lampshade, and a raised first locking portion is provided at the end of the first elastic arm. The first locking portion is used to snap onto the side of the locking boss away from the first light outlet, and the two sides of the bottom of the lampshade respectively abut against the locking boss.

[0014] As an optional embodiment, the lamp also includes a lens, and a second elastic arm is provided on both sides of the lens. The end of the second elastic arm is provided with a raised second locking portion, and the second locking portion is used to snap onto the side of the locking boss away from the first light outlet.

[0015] As an optional embodiment, a positioning column is provided at the bottom of the lampshade, and a mounting plate for mounting the first light board is provided on the inner side of the shell, and the positioning column is sequentially passed through the lens, the first light board and the mounting plate.

[0016] As an optional embodiment, the inner wall of the shell is provided with a mounting boss located on the side of the locking boss away from the first light outlet, the mounting plate is connected to the side of the mounting boss away from the first light outlet, the lens is provided with a raised portion located in the space between the two mounting bosses, the side of the lens close to the first light outlet is provided with a first groove sunken into the raised portion, the bottom of the first groove is provided with a raised light-transmitting portion, and the side of the raised portion close to the first light board is provided with a second groove sunken into the light-transmitting portion.

[0017] Compared to the prior art, the lamp of the present invention has the following beneficial effects: the light source is typically located at the first light port, and light emitted by the light source enters the lampshade through the first light port and is emitted through the second light port. As the illumination light passes through the lampshade, the ridges on the inner side of the inner cover refract and scatter the light multiple times, dispersing the concentrated strong light from the light source into a more uniform beam. This reduces the glare effect when the illumination light is emitted from the lampshade. This effectively reduces the stinging sensation caused by direct light, making the illuminated area softer and improving visual comfort (e.g., in household lamps, car taillights, etc.).

[0018] Secondly, the inner and outer cover parts are arranged in a coordinated manner and are both made of translucent materials. Therefore, in specific applications, part of the illumination light passes through the inner cover part and is emitted through the side walls of the outer cover part. It should be noted that the inner and outer cover parts are not simply superimposed. The two parts achieve multiple functional optimizations through the combination of structure and optical properties. For example, in terms of optical effect, the illumination light directly shines on the inner cover part, which is responsible for the initial diffusion of light and reduces the glare caused by direct light from the light source. The outer cover part refracts and diffusely reflects the light a second time, making the final emitted light more uniform and softer, avoiding glare. Alternatively, in terms of light control direction, the inner and outer cover parts can control the light projection range through structural designs at different angles.

[0034] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0035] See also Figures 1 to 2 , an embodiment of the present application provides a lamp, the lampshade 400 is made of a transparent material, the lampshade 400 includes an inner cover part 410 and an outer cover part 420, the inner cover part 410 is provided with a first light port 411 and a second light port 412, and the cross-section of the inner cover part 410 is gradually expanded from the first light port 411 to the second light port 412, the outer cover part 420 is located on the outside of the inner cover part 410, one end of the outer cover part 420 is connected to the second light port 412, and the other end of the outer cover part 420 is spaced apart from the inner cover part 410; wherein, along the circumferential direction of the inner cover part 410, the inner side of the inner cover part 410 is sequentially provided with ridges 430, and each of the ridges 430 extends from the first light port 411 to the second light port 412.

[0036] In a specific application, the light source is typically located at the first light port 411. Light emitted by the light source enters the lampshade 400 through the first light port 411 and is emitted through the second light port 412. As the illumination light passes through the lampshade 400, the ridges 430 on the inner side of the inner cover portion 410 refract and scatter the light multiple times, dispersing the concentrated strong light emitted by the light source into a more uniform beam. This reduces the glare effect when the illumination light is emitted from the lampshade 400. This effectively reduces the stinging sensation caused by direct light, making the illuminated area softer and improving visual comfort (e.g., in household lamps, car taillights, etc.).

[0037] Secondly, the inner cover 410 and outer cover 420 are arranged in a coordinated manner and are both made of light-transmitting materials. Therefore, in actual use, some of the illumination light passes through the inner cover 410 and is emitted through the sidewalls of the outer cover 420. It should be noted that the inner cover 410 and outer cover 420 are not simply superimposed. Through the coordination of their structures and optical properties, they achieve multiple functional optimizations. For example, in terms of optical effect, the illumination light directly shines on the inner cover 410, which is responsible for initially diffusing the light and reducing glare caused by direct light from the light source. The outer cover 420 performs secondary refraction and diffuse reflection on the light, making the final emitted light more uniform and softer, avoiding glare. Alternatively, in terms of light control direction, the inner cover 410 and outer cover 420 can control the light projection range through structural designs at different angles.

[0038] In some implementations, see Figure 1 The ridges 430 are configured to ensure that the incident angle of light entering the inner cover portion 410 is greater than or equal to the critical angle of the inner cover portion 410. The inner cover portion 410 is made of different materials, and the inner cover portion 410 corresponds to different critical angles. For example, if the inner cover portion 410 is made of a PMMA light-transmitting plate, the critical angle corresponding to the inner cover portion 410 is approximately 42°; if the inner cover portion 410 is made of a glass light-transmitting plate, the critical angle corresponding to the inner cover portion 410 is approximately 41° to 43°; if the inner cover portion 410 is made of a PC light-transmitting plate, the critical angle corresponding to the inner cover portion 410 is approximately 38° to 39°.

[0039] It will be appreciated that the angle of incidence of light entering the inner cover portion 410 is greater than or equal to the critical angle of the inner cover portion 410. With this arrangement, the inner side of the inner cover portion 410 can serve as a light path, with the majority of the illumination light being refracted back and forth within the inner cover portion 410 rather than being directly transmitted, until it is emitted through the circumferential end surfaces surrounding the second light port 412, thereby further reducing the glare effect of the illumination light. Simultaneously, only a small portion of the illumination light passes through the inner cover portion 410, thereby illuminating the inner side of the outer cover portion 420, thereby providing a brighter display effect on the outer cover portion 420, but without producing a brighter effect, thereby enabling the lampshade to present an optimal appearance.

[0040] In addition, by setting the ridge 430, the refraction path of the light can be changed by designing the ridge 430. Even if the incident angle is slightly smaller than the critical angle, the transmission can be limited by multiple refractions, thereby ensuring that the light is refracted within the inner cover portion 410 and emitted from the circumferential end faces around the second light port 412.

[0041] Furthermore, the outer surface of the inner cover portion 410 is smooth. It is understood that during the back-and-forth refraction process of the illumination light within the inner cover portion 410, the outer surface of the inner cover portion 410 is smooth. This configuration effectively ensures that the illumination light is continuously refracted within the inner cover portion 410 and emitted from the circumferential end surface around the second optical port 412.

[0042] In some embodiments, see Figure 1The cross-section of the rib 430 is gradually enlarged from the first light opening 411 to the second light opening 412. It is understandable that the cross-section of the inner cover portion 410 is gradually enlarged from the first light opening 411 to the second light opening 412, and the rib 430 is gradually enlarged in the circumferential dimension of the inner cover portion 410. In this manner, the rib 430 gradually enlarges along with the size of the lampshade 400. The rib 430 can fully cover the inner surface of the inner cover portion 410, thereby allowing the rib 430 to fully refract and scatter the illumination light, dispersing the intense light emitted by the concentrated light source into a more uniform beam, that is, reducing the glare effect when the illumination light is emitted from the lampshade 400.

[0043] In some embodiments, the sides of adjacent ridges 430 are connected to form reflective grooves 431 between adjacent ridges 430. The cross-section of the ridges 430 is triangular, or the cross-section of the ridges 430 is an arc-shaped convex, or the ridges 430 are arranged in a structural form.

[0044] It can be understood that the ridges 430 are arranged in the above-mentioned manner, and the ridges 430 fully cover the inner surface of the inner cover portion 410, thereby further enabling the ridges 430 to fully refract and scatter the illumination light, and disperse the strong light emitted by the concentrated light source into a more uniform light beam, that is, reducing the glare effect when the illumination light is emitted from the lampshade 400.

[0045] This application discloses a lamp, see Figure 1 、 Figure 3 and Figure 4 , including a shell 100, a first lamp board 200 and the above-mentioned lampshade 400, the shell 100 includes an outer shell part 110, the outer shell part 110 is provided with a first light output port 111, the inner wall of the outer shell part 110 is provided with a locking boss 113 and a mounting boss 120, and the locking boss 113 is located between the first light output port 111 and the locking boss 113; the first lamp board 200 is arranged on the mounting boss 120 on the inner side of the shell 100; first elastic arms 440 are respectively provided on both sides of the bottom of the lampshade 400, and a raised first locking portion 441 is provided on the end of the first elastic arm 440, and the first locking portion 441 is used to snap on the side of the locking boss 113 away from the first light output port 111, and the two sides of the bottom of the lampshade 400 respectively abut against the locking boss 113.

[0046] In which, a first guide slope 1131 is provided on the side of the locking boss 113 away from the shell part 110, and a second guide slope 442 is provided on the side of the first locking part 441 that slides relative to the first guide slope 1131, and the first locking part 441 is used to be snapped to the side of the locking boss 113 away from the first light outlet 111.

[0047] Specifically, when the lampshade 400 is being installed, the first guide bevel 1131 and the second guide bevel 442 slide relative to each other, the first elastic arm 440 elastically deforms toward the side away from the locking protrusion 113, and the first locking portion 441 passes over the locking protrusion 113. At this time, the two sides of the bottom of the lampshade 400 respectively contact the sides of the two locking protrusions 113 close to the first light outlet 111, the first elastic arm 440 returns to its normal shape, and the first locking portion 441 is locked with the side of the locking protrusion 113 away from the first light outlet 111, thereby conveniently installing the lampshade 400 on the first light outlet 111.

[0048] In some embodiments, see Figures 3 to 5 The lamp further includes a lens 300, which is disposed between the lamp panel and the lampshade 400. Specifically, second elastic arms 310 are vertically extended from both sides of the lens 300. The ends of the second elastic arms 310 are provided with raised second locking portions 320. The second locking portions 320 are used to snap onto the side of the locking boss 113 away from the first light outlet 111. The second locking portions 320 are provided with a third guide inclined surface 321 that slides relative to the first guide inclined surface 1131.

[0049] Specifically, when the lens 300 is installed, the first guide bevel 1131 and the third guide bevel 321 slide relative to each other, the second elastic arm 310 elastically deforms toward the side away from the locking boss 113, and the second locking portion 320 passes over the locking boss 113. At this time, the side of the lens 300 closer to the first lamp board 200 is placed in contact with the side of the first lamp board 200 with the lamp beads, the second elastic arm 310 returns to its normal shape, and the second locking portion 320 snaps into the side of the locking boss 113 away from the first light outlet 111, thereby conveniently installing the lens 300 in the housing 100.

[0050] In some embodiments, see also Figure 2The bottom of the lampshade 400 is provided with a positioning post 450, and the lens 300, the first lamp board 200, and the mounting boss 120 are provided with aligned through-holes. When the lampshade 400 is installed in the first light outlet 111, the positioning post 450 is sequentially inserted into the through-hole of the lens 300, the through-hole of the first lamp board 200, and the through-hole of the mounting boss 120, thereby ensuring the positioning of the lampshade 400, the first lamp board 200, and the lens 300, and further ensuring that the lampshade 400, the first lamp board 200, and the lens 300 can be accurately installed. In addition, when the lampshade 400 is snap-connected to the shell 100, the lampshade 400 uses the positioning column 450 to position the lens 300 and the first lamp board 200 on the mounting boss 120. In this way, no additional screws are required to fix the lens 300 and the first lamp board 200 to the mounting plate 114, thereby facilitating the installation of the first lamp board 200 and the lens 300, thereby facilitating the assembly of the lamp.

[0051] Of course, if a mounting plate 114 for mounting the first lamp board 200 is provided on the mounting boss 120, the positioning column 450 is sequentially passed through the lens 300, the first lamp board 200 and the mounting plate 114, and the lampshade 400 uses the positioning column 450 to position the lens 300 and the first lamp board 200 on the mounting plate 114. In this way, no additional screws are required to fix the lens 300 and the first lamp board 200 to the mounting plate 114, thereby facilitating the installation of the first lamp board 200 and the lens 300, thereby facilitating the assembly of the lamp.

[0052] In some embodiments, see Figure 4 and Figure 5 , mounting bosses 120 are provided on both sides of the inner wall of the outer shell 110, and the two mounting bosses 120 are arranged at intervals in the same plane. The side of the two mounting bosses 120 away from the first light outlet 111 is assembled with a mounting plate 114, and the first lamp board 200 is arranged on the side of the mounting plate 114 close to the first light outlet 111.

[0053] It can be understood that the mounting plate 114 and the shell 100 are composed of two components. The mounting plate 114 is used to install the first lamp board 200, and the shell 100 is used to install the lampshade 400. This arrangement simplifies the structural difficulty of the shell 100, thereby facilitating mass production of the shell 100.

[0054] Further, see Figure 6 and Figure 7, a raised portion 330 is provided on the side of the lens 300 close to the first light board 200. The raised portion 330 is located in the space between the two mounting bosses 120 and is roughly truncated in shape. A first recessed groove 331 is provided on the side of the lens 300 close to the first light outlet 111, which is recessed to the raised portion 330. At the same time, a raised light-transmitting portion 340 is provided at the bottom of the first recessed groove 331, and a second recessed groove 341 is provided on the side of the raised portion 330 close to the first light board 200, which is recessed to the light-transmitting portion 340. With this arrangement, when the lens 300 is installed on the first light board 200 close to the first light outlet 111, the lamp beads on the upper side of the first light board 200 are arranged corresponding to the openings of the second recessed grooves 341 on the lens 300 to receive the light transmitted by each lamp bead.

[0055] Specifically, each lamp bead on the first light panel 200 emits light into the second recessed groove 341 of the raised portion 330. The light then passes through the second recessed groove 341, through the light-transmitting portion 340, and out into the external environment through the first recessed groove 331. With this arrangement, the first and second recessed grooves 331, 341, and the light-transmitting portion 340 optimize the light propagation path as the light passes through the lens 300, reducing visual discomfort caused by glare and scattering.

[0056] It is understood that the lens 300, through the provision of the raised portion 330, can be positioned between the two mounting bosses 120, thereby fitting against the side of the first light board 200 closest to the lens 300. Each lamp bead is positioned corresponding to the first recessed groove 331, thereby allowing the lens 300 and the first light board 200 to be mounted together. Furthermore, the provision of the raised portion 330 on the lens 300 allows for a first recessed groove 331 of sufficient depth on the side of the lens 300 facing the first light outlet 111, with a raised light-transmitting portion 340 provided at the bottom of the first recessed groove 331, thereby enabling better processing of the incoming light.

[0057] To facilitate mounting the first light board 200 on the mounting boss 120, in some embodiments, the mounting boss 120 is provided with a connecting groove 121 along its extension direction, on a side of the mounting boss 120 away from the first light outlet 111. The connecting groove 121 is generally U-shaped. A first fastening screw is provided on the mounting plate 114. The first fastening screw passes through the mounting plate 114 and connects with the connecting groove 121, thereby conveniently mounting the first light board 200 on the mounting boss 120.

[0058] It should be noted here that the mounting boss 120 needs to be provided with a connecting groove 121 of sufficient depth. Accordingly, the mounting boss 120 needs to be set at a sufficiently large height. Therefore, the lens 300 is provided with a raised portion 330, and the raised portion 330 can pass through the space between the two mounting bosses 120 to be connected to the first lamp board 200.

[0059] In some embodiments, see Figure 4 , a strip boss 115 is provided on the side of the mounting boss 120 close to the first light outlet 111, and a connecting groove 121 is recessed into the strip boss 115. Thus, the mounting boss 120 can be provided with a connecting groove 121 of sufficient depth at the position of the strip boss 115 for the first fastening screw to be inserted and connected. At the same time, the locking boss 113 is located on the outside of the strip boss 115, and the strip boss 115 and the locking boss 113 are spaced apart to form a clearance gap 1132 therebetween for the second elastic arm 310 to pass through. It can be understood that the mounting boss 120 and the locking boss 113 adopt the above-mentioned structural form, and both fully utilize the internal space of the housing 100, avoiding the lamp being too large in size.

[0060] In some embodiments, see Figure 4 and Figure 5 The lamp also includes a second lamp board 500. The outer shell 110 is provided with a second light outlet 112. The first light outlet 111 and the second light outlet 112 are arranged at relative positions of the outer shell 110, that is, the two are arranged in opposite directions. The second lamp board 500 is arranged on the side of the mounting plate 114 near the second light outlet 112. The second lamp board 500 is provided with a second fixing screw. The edge of the mounting plate 114 is provided with a clearance notch. The second fixing screw can extend into the connecting groove 121 through the clearance notch to connect with the connecting groove 121. As a result, the second lamp board 500 is fixedly installed on the side of the mounting plate 114 away from the first lamp board 200. It can be understood that the mounting plate 114 is detachably connected to the mounting boss 120 by the first fixing screw. With this arrangement, the second lamp board 500 can be preferentially installed on the mounting plate 114, and the mounting plate 114 is then installed on the mounting boss 120, thereby facilitating the installation of the lamp.

[0061] In some embodiments, see 3 and Figure 4, the lamp can be arranged in a straight segment, and accordingly, the housing 100, the first light board 200 and the lens 300 are all arranged to extend in a straight line, so that a straight lamp can be assembled. Of course, in other possible embodiments, the lamp can be arranged in an arc segment, and accordingly, the housing 100, the first light board 200 and the lens 300 are all arranged to extend in an arc, so that a curved lamp can be assembled; or, the lamp can be arranged in a circular shape, and accordingly, the housing 100, the first light board 200 and the lens 300 are all arranged in a circular shape, so that a circular lamp can be assembled; or, the lamp can be arranged in a polygonal shape, and accordingly, the housing 100, the first light board 200 and the lens 300 are all arranged in a polygonal shape, so that a polygonal lamp can be assembled.

[0062] The technical means disclosed in the solutions of the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
