[0042] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0043] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0044] See also Figures 1 to 18As shown, the present invention discloses a lamp 100, which can be a lighting product such as a ceiling lamp, a wall lamp or a decorative lamp.

[0045] In a preferred embodiment of the present invention, the lamp 100 includes a chassis 10, a light source module 20, a decorative plate 30 and a frameless lampshade 40. The light source module 20 is arranged on the chassis 10, and includes a first light source assembly 21 and a second light source assembly 22. The decorative plate 30 is fixedly connected to the chassis 10 and is covered on the outside of the first light source assembly 21. The frameless lampshade 40 is fixedly connected to the chassis 10 and is surrounded on the outside of the decorative plate 30 and is covered on the outside of the second light source assembly 22. That is, the first light source assembly 21 is arranged in the decorative plate 30 to form the main lighting, and the second light source assembly 22 is arranged in the frameless lampshade 40 to form the auxiliary lighting, so as to form the effect that the auxiliary lighting surrounds the main lighting, and realize a variety of light emitting effects.

[0046] In another embodiment of the present invention, the lamp 100 also includes a light emitting plate 50 arranged inside the decorative panel 30. Part of the light emitted by the first light source assembly 21 passes through the decorative panel 30 and then is emitted through the light emitting plate 50 to form a multi-layer surrounding light-emitting effect, thereby improving the light efficiency of the lamp 100.

[0047] In order to clearly explain the structure of the lamp 100, the following description assumes that the light emitting plate 50 is arranged in the center, the decorative plate 30 surrounds the light emitting plate 50, and the frameless lampshade 40 surrounds the decorative plate 30. However, it is known to those skilled in the art that the lamp 100 may not include the light emitting plate 50, or the light emitting plate 50 may be arranged in a non-central area of ​​the decorative plate 30, and the present invention is not limited to this. In addition, the decorative plate 30 and the light emitting plate 50 may be structures such as a diffuser plate or a light guide plate, or other structures, and may be specifically arranged as needed, and no limitation is made here.

[0048] See also Figures 1 to 18 As shown, the lamp 100 includes a light emitting plate 50, a decorative plate 30, a frameless lampshade 40 and a light source module 20. The light emitting plate 50, the decorative plate 30 and the frameless lampshade 40 are sequentially arranged from the center of the lamp 100 to the outside. That is, the light emitting plate 50 is located on the inner side of the decorative plate 30, and the frameless lampshade 40 is arranged on the outer side of the decorative plate 30 and surrounds the decorative plate 30. Preferably, the light emitting plate 50 is circular in shape and is located in the center of the decorative plate 30. Of course, the light emitting plate 50 can also be other shapes, or be arranged in a non-central area of ​​the decorative plate 30, which is not limited here.

[0049] The light source module 20 includes a first light source assembly 21 and a second light source assembly 22, wherein the first light source assembly 21 includes a first light emitting element 211 and a second light emitting element 212, wherein the first light emitting element 211 is disposed in the receiving portion 35 of the decorative plate 30 and emits light through the light emitting area 321, and the second light emitting element 212 is disposed in the receiving portion 343 of the decorative plate 30 and emits light through the first extension portion 341 on the decorative plate 30. The second light source assembly 22 is disposed at the periphery of the first light source assembly 21 and below the frameless lampshade 40 to provide auxiliary lighting.

[0050] See also Figures 5 and 6 Combined with Figures 1 to 4 As shown, the chassis 10 is provided with a convex rib 121, a mounting rib 122 and an outer frame 123 from the inside to the outside, so as to respectively form a first mounting position 111 for mounting the light output panel 50, a second mounting position 112 for mounting the decorative panel 30 and a third mounting position 113 for mounting the frameless lampshade 40.

[0051] Specifically, the chassis 10 is formed with a convex rib 121 extending upward from its surface. In the present embodiment, the convex rib 121 is arranged in the central area of ​​the chassis 10 and is arranged in a circular shape, thereby forming a circular first mounting position 111 for mounting the light emitting plate 50. An outer frame 123 is formed extending upward from the edge of the chassis 10. The outer frame 123 matches the shape of the chassis 10 and is also arranged in an annular shape, surrounding the edge of the chassis 10, and the diameter of the outer frame 123 is the same as the diameter of the chassis 10. That is, the outer frame 123 is the outer frame of the chassis 10. The mounting rib 122 is arranged between the convex rib 121 and the outer frame 123, wherein a second mounting position 112 for mounting the decorative plate 30 is formed between the convex rib 121 and the mounting rib 122. A third mounting position 113 for mounting the frameless lampshade 40 is formed between the mounting rib 122 and the outer frame 123. Preferably, the mounting rib 122 is disposed close to the outer frame 123 , so as to increase the area of ​​the second mounting position 112 , thereby making the decorative panel 30 serving as the main lighting have a larger light-emitting area, thereby improving the lighting brightness of the lamp 100 .

[0052] See also Figures 1 to 10 As shown, the decorative plate 30 is disposed above the first light source assembly 21 to form a main lighting assembly. The decorative plate 30 includes a light-transmitting light-emitting portion 31 and a first connecting portion 33 and a second connecting portion 34 extending from the light-emitting portion 31 toward the chassis 10. The first connecting portion 33 and the second connecting portion 34 are both in contact with the chassis 10 and form a receiving portion 35 for receiving the first light source assembly 21. The first light source assembly 21 is disposed in the receiving portion 35 and is disposed toward the light-emitting portion 31.

[0053] Furthermore, in order to increase the light emitting effect of the decorative panel 30 so that it can emit light of a special pattern as needed, a film 32 printed with a special pattern is provided on the surface of the translucent light emitting portion 31 . Preferably, the film 32 is provided on the outer side of the light emitting portion 31 .

[0054] The film 32 includes a light emitting area 321 and a light shielding area 322, wherein the light emitting area 321 can transmit light, while the light shielding area 322 blocks light and cannot transmit light. By designing the shape of the light emitting area 321 on the film 32, setting a desired pattern on the film 32, and leaving a hollow at the position where light is required to be emitted, the light emitting area 321 is formed, so that the lamp 100 can achieve a variety of irregular pattern light emitting effects, and the cost is low.

[0055] like Figure 7 and Figure 8 Combined with Figures 1 to 6 As shown, the light shielding area 322 is provided with a coating on the film 32 by silk screen printing, and the coating is not light-transmissive, thereby forming the light shielding area 322. Optionally, the position where light is required to be emitted can be reserved for hollowing out on the film 32 as needed, so that it can be used as the light emitting area 321 for light emission. Preferably, the light emitting area 321 is recessed to a certain extent relative to the light shielding area 322, so that light emitting effects of different depths can be formed to form different patterns.

[0056] Furthermore, a light emitting groove 311 corresponding to the light emitting area 321 is provided on the light emitting portion 31, and the light emitting groove 311 is provided on the side of the light emitting portion 31 facing the film 32. This arrangement is to avoid the phenomenon of glue shadow on the film 32. As is known to all, the film 32 is attached to the light emitting portion 31. Due to the material limitation of the film 32, it is easy for tiny air or dust to exist between it and the surface of the light emitting portion 31, and the air or dust can change the direction of the light, so that the light emitted by the first light source assembly 21 is easy to form uneven light and shadow of different depths after being emitted through the light emitting area 321, that is, glue shadow phenomenon, which affects the light emitting effect of the decorative plate 30. By setting a light emitting groove 311 on the side of the light emitting portion 31 facing the film 32, the light emitting area 321 of the film 32 is not in contact with the light emitting portion 31, so that the light emitted by the first light emitting element 211 in the first light source assembly 21 first passes through the light emitting groove 311 and then is emitted through the light emitting area 321 to form uniform light, thereby avoiding the occurrence of glue shadow phenomenon and improving user experience.

[0057] Furthermore, the width of the light emitting groove 311 is greater than or equal to the width of the light emitting area 321 , thereby improving the light emitting effect of the decorative plate 30 .

[0058] Furthermore, the first light source assembly 21 is fixedly disposed on the chassis 10 and is electrically connected to the driving device on the chassis 10. Preferably, the first light source assembly 21 is disposed corresponding to the light emitting area 321 and the light emitting groove 311, so that the light emitted by the first light source assembly 21 can be directly emitted through the light emitting portion 31 and the light emitting area 321, thereby improving the light emitting effect of the lamp 100, for example, brightness, etc.

[0059] In a preferred embodiment, the lamp 100 further includes a decorative member 36. The decorative member 36 may be made of a light-transmitting material, so that a lighting area in the shape of the decorative member 36 is added to the lighting pattern of the lamp 100 to improve the lighting effect. Of course, the decorative member 36 may also be made of an opaque material, so that light and shadow in the shape of the decorative member 36 are added to the lighting pattern of the lamp 100 to improve the lighting atmosphere. The present invention is not limited here.

[0060] See also Figures 6 to 8 As shown, the decorative element 36 is disposed on the light emitting portion 31 , and a mounting hole 315 for mounting the decorative element 36 is provided on the light emitting portion 31 , and the mounting hole 315 is at least partially located on the light emitting area 321 of the film 32 , so that the lamp 100 can project the shape of the decorative element 36 .

[0061] The mounting hole 315 is provided through the light-emitting portion 31, and the decorative member 36 is mounted in the mounting hole 315. The mounting hole 315 is provided with a first clamping structure 3151 for clamping with the decorative member 36, and the first clamping structure 3151 extends from the mounting hole 315 in a direction away from the light-emitting portion 31. The decorative member 36 is provided with a support leg 361 extending into the mounting hole 315, and the end of the support leg 361 is provided with a second clamping structure 3611 that is clamped with the first clamping structure 3151. In this embodiment, the second clamping structure 3611 is a hook, which is clamped to the first clamping structure 3151. In other embodiments, the first clamping structure 3151 and the second clamping structure 3611 may also be other clamping structures, and the present invention is not limited to this.

[0062] Furthermore, a plurality of first light-emitting elements 211 are disposed below the decorative member 36 to further enhance the lighting effect of the decorative member 36 .

[0063] The position of the film 32 corresponding to the decorative element 36 is hollowed out, that is, the decorative element 36 is arranged at the light emitting area 321 of the film 32, and the light emitted by the first light emitting element 211 in the first light source assembly 21 is emitted after passing through the light emitting portion 31 and the light emitting area 321 to form a light emitting area or a light and shadow area with the same shape as the decorative element 36. For example, in this embodiment, the decorative element 36 is in the shape of a transparent star, so that the image of the star can be projected. The decorative element 36 is convexly arranged on the light emitting portion 31 and extends from the light emitting portion 31 along the light emitting direction of the light.

[0064] In other embodiments, the decorative member 36 may also be in other shapes, or the decorative member 36 may be recessed on the light emitting portion 31 , so that the light emitted by the first light source assembly 21 generates a special light effect after passing through the decorative member 36 .

[0065] Furthermore, the decorative plate 30 is fixedly connected to the chassis 10, and a fixing portion 312 protruding toward the chassis 10 is provided on the side of the light emitting portion 31 facing the chassis 10, and the fixing portion 312 is arranged in the light shielding area 322, and a fastener passes through the fixing portion 312 and is fixedly connected to the chassis 10. By arranging the fixing portion 312 in the light shielding area 322, the fixing portion 312 is prevented from blocking light and affecting the light emitting effect, and the fixing portion 312 is hidden, thereby improving the aesthetics of the lamp 100.

[0066] The decorative panel 30 includes a first connection portion 33 and a second connection portion 34 extending from the light emitting portion 31 toward the chassis 10 , wherein the first connection portion 33 is disposed close to the mounting rib 122 of the chassis 10 , and the second connection portion 34 is disposed in the middle of the first connection portion 33 , surrounding the mounting area 313 on the light emitting portion 31 .

[0067] Furthermore, the first connecting portion 33 is arranged on the side of the mounting rib 122 facing the outer frame 123 to abut against the frameless lampshade 40, so that the frameless lampshade 40 is fixed to the chassis 10 using the decorative panel 30. Moreover, such a setting can also hide the connection structure between the frameless lampshade 40 and the chassis 10, making the appearance of the lamp 100 more beautiful.

[0068] The second connecting portion 34 includes a first extending portion 341 and a second extending portion 342 disposed adjacent to each other. The first extending portion 341 is disposed away from the first connecting portion 33 relative to the second extending portion 342. An accommodating portion 343 for accommodating a portion of the first light source assembly 21 is formed between the first extending portion 341 and the second extending portion 342.

[0069] The first light emitting element 211 is disposed between the first connecting portion 33 and the second extending portion 342, and emits light through the light emitting area 321. The second light emitting element 212 is disposed in the accommodating portion 343 between the first extending portion 341 and the second extending portion 342, and emits light after passing through the first extending portion 341. Preferably, the inner side of the accommodating portion 343 is a curved surface 3421, and the curved surface 3421 is a reflective surface. In this arrangement, the light emitted by the second light emitting element 212 is reflected by the curved surface 3421 and then emitted through the first extending portion 341, thereby improving the lighting effect of the lamp 100.

[0070] The light emitting portion 31 is provided with a mounting area 313 that penetrates the light emitting portion 31. In this embodiment, the mounting area 313 is used to mount the light emitting plate 50. In other embodiments, the light emitting plate 50 may not be provided, or the light emitting plate 50 may be provided with other structures, such as a ceiling lamp or a downlight.

[0071] The first extension portion 341 and the second extension portion 342 are both disposed around the installation area 313 , and the first extension portion 341 is disposed closer to the installation area 313 relative to the second extension portion 342 .

[0072] Preferably, the first extension portion 341 is made of a light-transmitting material, extends vertically downward from the light-emitting portion 31, and surrounds the outer side of the light-emitting plate 50. The second extension portion 342 extends vertically downward from the light-emitting portion 31, and its side facing the first extension portion 341 is a curved surface 3421, that is, one end of the second extension portion 342 is connected to the first extension portion 341, and the other end is in contact with the chassis 10. Preferably, the curved surface 3421 is a reflective surface. When the second light-emitting element 212 emits light toward the top, the light is reflected by the curved surface 3421 and then emitted toward the light-emitting plate 50 at the top through the first extension portion 341 on the side. Such an arrangement enables at least part of the light emitted by the second light-emitting element 212 arranged under the decorative plate 30 to first pass through the first extension portion 341 of the decorative plate 30 and then be emitted through the light emitting plate 50. That is, at least part of the light emitted by the second light-emitting element 212 first passes through the first extension portion 341 in the form of side light, and then is emitted from the light emitting plate 50 in the form of front light, so as to increase the sense of mystery of the light emitting plate 50 and improve the light emitting effect of the light emitting plate 50.

[0073] Furthermore, the light emitting plate 50 abuts against the side wall of the first extension portion 341 and is surrounded by the first extension portion 341, so that the light passing through the first extension portion 341 can enter from the side wall of the light emitting plate 50 and be emitted from the front, and finally the light emitting plate 50 is illuminated by the second light emitting element 212. That is, in the present invention, although the first light emitting element 211 and the second light emitting element 212 in the first light source assembly 21 are both arranged below the light emitting portion 31 of the decorative plate 30, they are finally projected out through the light emitting portion 31 of the decorative plate 30 and the light emitting plate 50, respectively, so as to achieve different lighting effects.

[0074] Furthermore, the light emitting plate 50 and the light emitting portion 31 have a height difference in the vertical direction, wherein the height of the light emitting plate 50 is lower than the height of the light emitting portion 31. With such a configuration, a portion of the light emitted by the second light emitting element 212 is directly emitted through the first extension portion 341 (i.e., side emission), and another portion is emitted through the first extension portion 341 and then through the light emitting plate 50 (i.e., front emission). That is, the second light emitting element 212 has both side emission and front emission, so as to increase the atmosphere of the lamp 100 and achieve different light emission effects.

[0075] Optionally, the surface of the light emitting plate 50 is an uneven surface, that is, it is concave-convex. Such a configuration can make the light emitted by the second light emitting element 212 more similar to the surface of the moon, making the light emitting effect of the lamp 100 more diverse.

[0076] Optionally, an edge portion 314 is provided on a side of the light emitting portion 31 close to the mounting area 313, and the edge portion 314 is arranged on a side of the first extension portion 341 away from the second extension portion 342, and extends to the top of the light emitting plate 50 to partially overlap with the light emitting plate 50, so that the light can form a halo at the edge of the light emitting area of ​​the light emitting plate 50, thereby improving the light emitting effect of the lamp 100.

[0077] See also Figures 1 to 18 As shown, the frameless lampshade 40 is arranged at the third installation position 113 of the chassis 10, and is arranged around the decorative plate 30. The second light source assembly 22 is fixedly arranged in the third installation area 103 of the chassis 10, that is, located below the frameless lampshade 40, and is electrically connected to the driving device, and emits light toward the frameless lampshade 40. Preferably, the second light source assembly 22 surrounds the chassis 10 and is distributed along the extension direction of the frameless lampshade 40, so that the frameless lampshade 40 emits light in a ring shape.

[0078] See also Figures 10 to 18 The frameless lampshade 40 shown includes an outer lampshade 41, which is curved and bulges outward along the light emitting direction. That is, the cross-sectional area of ​​the outer lampshade 41 is U-shaped. The outer lampshade 41 extends to the outside of the outer frame 123 of the chassis 10, and contains and wraps the outer frame 123, so that the outer frame of the lamp 100 is invisible, thereby improving the aesthetics of the lamp 100.

[0085] Furthermore, since the first connection portion 33 of the decorative panel 30 extends to the outside of the mounting rib 122 to surround the mounting rib 122, the first connection portion 33 will abut against the side of the step portion 4121 of the second edge 412 away from the chassis 10. In the horizontal direction, the position where the first connection portion 33 abuts against the step portion 4121 is arranged close to the outer frame 123 relative to the first clamping portion 4122, so that the outer lamp cover 41 can be fixed on the chassis 10 by the clamping fit between the first clamping portion 4122 and the second clamping portion 1221 and the abutment fit between the first connection portion 33 and the step portion 4121.

[0086] Furthermore, in order to improve the light output effect, an inner lampshade 42 is provided inside the outer lampshade 41. The inner lampshade 42 can be made of a transparent material such as a diffuser, and the outer lampshade 41 can be a transparent, misty white or milky white diffuser to improve the aesthetics of the lamp 100.

[0087] The inner lampshade 42 is disposed in the third mounting position 113 and is located inside the outer lampshade 41. The inner lampshade 42 includes a third edge 421 and a fourth edge 422. The third edge 421 is disposed close to the mounting rib 122 relative to the fourth edge 422. That is, the third edge 421 is disposed close to the second edge 412, and the fourth edge 422 is disposed close to the first edge 411.

[0088] Preferably, a first combining portion 4211 is provided at the third edge 421 , and a second combining portion 4124 is provided at a position of the second edge 412 corresponding to the first combining portion 4211 , and the first combining portion 4211 and the second combining portion 4124 are correspondingly engaged.

[0089] In this embodiment, the first joint portion 4211 is a buckle formed by extending the third edge 421 in a direction close to the second edge 412, and the second joint portion 4124 is a bayonet, and the buckle extends into the bayonet to form a buckle connection. In other embodiments, the first joint portion 4211 can also be a bayonet, and the second joint portion 4124 is a buckle, or the first joint portion 4211 and the second joint portion 4124 are other forms of buckle connection, and the present invention is not limited to this.

[0090] Furthermore, a reinforcing rib 13 is formed between the mounting rib 122 and the outer frame 123, and a limiting portion 131 is provided on the reinforcing rib 13. The limiting portion 131 is used to limit and fix the fourth edge 422 of the inner lampshade 42 to prevent the fourth edge 422 from deforming in the direction of the third edge 421. That is, a limiting groove is formed between the limiting portion 131 and the first edge 411 to limit and fix the fourth edge 422 of the inner lampshade 42 in the limiting groove.

[0091] Further, the fourth edge 422 extends to the abutment portion 4113 of the first edge 411 to provide a support for the fourth edge 422. Preferably, the connection between the fourth edge 422 and the abutment portion 4113 is an adapted arc surface to provide a guide for the fourth edge 422 to be installed on the abutment portion 4113. In addition, by extending the fourth edge 422 to the abutment portion 4113 of the first edge 411, the outer frame 123 can be clamped and fixed by the fourth edge 422 and the first edge 411.

[0092] Optionally, a protrusion 4114 cooperating with the outer frame 123 of the chassis 10 is provided on the abutting portion 4113 , so a clearance groove 4221 is provided at a position of the fourth edge 422 corresponding to the protrusion 4114 .
