Technical Field

[0001] The utility model belongs to the technical field of lighting lamps, and particularly relates to a lamp body component and a lamp. Background Art

[0002] As a surface light source, panel lights have the characteristics of soft, uniform and bright light, so they are widely used in spaces such as homes, offices or shopping malls.

[0003] Current panel lights primarily consist of a lamp panel, light source, driver, translucent panel, and cover. The translucent panel is often secured to the light outlet of the lamp panel via a cover. The edge of the cover often obscures the edge of the translucent panel, reducing the light output area of ​​the lamp. When multiple lamps are spliced ​​together, light from the cover edges can be blocked, creating dark edges between adjacent lamps. This prevents seamless light output from the spliced ​​lamps, impacting the overall aesthetics and lighting performance, and thus failing to fully meet consumer needs.

[0004] Therefore, it is of great significance to provide a lamp structure with a large light-emitting surface and capable of seamlessly splicing the light-emitting surfaces. Utility Model Content

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0048] Example 1:

[0049] Please see the attached Figure 1-8 This embodiment provides a lamp body assembly 100, which achieves an increase in the area of ​​the light emitting surface 111 and a borderless effect of the light emitting surface 111 by optimizing the structure.

[0050] Specifically, the lamp body assembly 100 includes a lamp panel 2 and a light emitting surface cover 1 detachably connected to the lamp panel 2. Figure 2 As shown, the lamp panel 2 includes a bottom plate 21 and side plates 22. The side plates 22 are connected to the edge of the bottom plate 21 and enclose the bottom plate 21 to form an accommodating space 23. The accommodating space 23 has a light outlet 24. The light outlet 24 is opposite to the bottom plate 21 and is away from the bottom plate 21. At the end where the light outlet 24 is located, the outer side of the side plate 22 extends toward the bottom plate 21 to form a first connecting portion 221.

[0051] like Figure 3 As shown, the light-emitting surface cover 1 includes a light-emitting portion 11 and a second connecting portion 12 integrally connected to the light-emitting portion 11. The light-emitting portion 11 is a light-transmitting structure, and one side of the light-emitting portion 11 is a light-emitting surface 111. Light passing through the accommodating space 23 can pass through the light-emitting portion 11 and be emitted from the light-emitting surface 111. The second connecting portion 12 is formed by the end of the light-emitting portion 11 extending in a direction away from the light-emitting surface 111, that is, the second connecting portion 12 is located below the light-emitting portion 11. A snap-fit ​​structure for connection is provided between the first connecting portion 221 and the second connecting portion 12, and the lamp panel 2 and the light-emitting surface cover 1 are assembled and fixed by the first connecting portion 221 and the second connecting portion 12.

[0052] When the light-emitting surface cover 1 is mounted on the lamp panel 2, the light-emitting portion 11 of the light-emitting surface cover 1 covers the light-emitting opening 24, and the second connecting portion 12 is located outside the first connecting portion 221 and engages with the first connecting portion 221. The first connecting portion 221 and the second connecting portion 12 are located entirely outside the side panel 22 and relatively below the light-emitting portion 11, thereby preventing the light-emitting opening 24 of the lamp panel 2 from being blocked by the connection between the lamp panel 2 and the light-emitting surface cover 1. This effectively increases the area of ​​the light-emitting surface 111 and gives the light-emitting surface 111 of the lamp body assembly 100 a borderless technical effect, facilitating a seamless connection during splicing.

[0053] Preferably, focus on Figure 2 、 Figure 5 and Figure 6 The side panel 22 tilts inward from the outside of the base plate 21 at the end where the light outlet 24 is located and ultimately connects to the base plate 21. The light outlet 24 extends entirely along a horizontal plane, and the plane where the light outlet is located has a normal line L. The first connecting portion 221 and the second connecting portion 12 are parallel to the normal line L. Therefore, when multiple lamp body assemblies 100 are spliced ​​together, the second connecting portions 12 of adjacent lamp body assemblies 100 can be closely attached to each other, ensuring the appearance of the spliced ​​lamp body assemblies 100 and further enhancing the seamless connection effect.

[0054] Furthermore, in a cross-section perpendicular to the bottom plate 21 and passing through the midline of the bottom plate 21, an angle θ is formed between the outer surface of the side plate 22 and the outer surface of the first connecting portion 221, and the angle θ is 35°≤θ≤50°. This allows the lamp panel 2 to have a suitable light control angle, thereby expanding the light output surface 111 while achieving a reasonable light intensity. In this embodiment, the angle θ is preferably 47.1°.

[0055] Figure 7 A partial optical path diagram of the lamp assembly 100 is given, and reference is made to Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 and Figure 8 The interior of the housing space 23 of the lamp panel 2 can be used to mount a light-emitting component. Light emitted by the light-emitting component passes through the lamp panel 2 and exits from the light-emitting portion 11 located above the light outlet 24. Preferably, the surface of the side panel 22 located within the housing space 23 is a reflective surface, which is used to control the path of light emitted by the light-emitting component, achieve anti-glare, and optimize the light output effect. The reflective surface can be formed by coating a reflective layer or adhering a reflective film.

[0056] In particular, the size of the light emitting portion 11 is preferably larger than the size of the light outlet 24. Figure 2 and Figure 8, the side panel 22 is in contact with the light emitting portion 11 in a linear form. Part of the light emitted by the light emitting component is emitted from the light outlet 24 after being reflected by the reflective surface. Among them, there is a part of the light that approaches the light outlet when reaching the reflective surface, and this part of the light is emitted toward the edge of the light outlet 24 after being reflected by the reflective surface. At this time, the part of the light outlet 11 covering the outside of the light outlet 24 can transmit this part of the light, optimize the light-emitting effect of the light-emitting edge of the lamp body assembly 100, and make the light of the lamp body assembly 100 uniform when it is emitted, further realizing a seamless lighting effect. In this embodiment, the edge of the light outlet 11 is transitionally connected to the second connecting portion 12 in an arc structure, and the second connecting portion 12 is located as a whole below the plane where the light outlet 24 is located, that is, the second connecting portion 12 extends from the side away from the light-emitting surface 111 toward the bottom plate 21 to ensure that the edge of the light outlet 11 has a good light-emitting effect.

[0057] In some embodiments, first connecting portions 221 are provided on any two or more edges of the lamp panel 2, and multiple first connecting portions 221 spaced apart on the same edge of the lamp panel 2 can be provided. In this embodiment, a first connecting portion 221 is provided on each edge of the lamp panel 2. Furthermore, to facilitate splicing of multiple lamp body assemblies 100 and increase structural strength, first notches 222 are provided between adjacent first connecting portions 221, and second notches 13 are provided between adjacent second connecting portions 12. When the light-emitting surface cover 1 is assembled with the lamp panel 2, the first notches 222 and the second notches 13 are connected.

[0058] Further, combined with reference Figure 2 and Figure 6 The snap-fit ​​structure includes a snap-fit ​​hole 31 and a snap-fit ​​block 32. In this embodiment, the snap-fit ​​hole 31 is provided on the first connecting portion 221, and the snap-fit ​​block 32 is provided on the second connecting portion 12 and is formed by the second connecting portion 12 protruding toward the first connecting portion 221. During installation, the light-emitting surface cover 1 is moved toward the lamp panel 2 until the snap-fit ​​block 32 of the second connecting portion 12 is inserted into the snap-fit ​​block 32, completing the fixation of the light-emitting surface cover 1 to the lamp panel 2. At this time, the light-emitting portion 11 covers the light outlet 24 and is in close contact with the upper edge of the side panel 22. This snap-fit ​​structure enables quick installation and fixation between the light-emitting surface cover 1 and the lamp panel 2, and provides stability.

[0059] Furthermore, the engaging hole 31 is an elongated hole extending parallel to the edge of the lamp panel 2, and the clamping block 32 is adapted to the engaging hole 31. The elongated engaging hole 31 and the clamping block 32 help increase the contact area between the light-emitting surface cover 1 and the lamp panel 2, improving stability after installation.

[0060] Example 2:

[0061] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the lamp body assembly 100 of embodiment 1. For the similarities, please refer to embodiment 1. The differences are described in detail below.

[0062] Please refer to Figures 9 to 11 The second connecting portion 12 is further provided with a stopper 5 for splicing and fixing. The stopper 5 and the clamping block 32 are arranged alternately along the extension direction of the edge of the lamp panel 2, so that the light-emitting surface cover 1 can smoothly approach the lamp panel 2 and be assembled with the lamp panel 2 without the stopper 5 blocking the clamping block 32.

[0063] Furthermore, on the second connecting portion 12, the clamping block 32 is located at the end close to the light emitting portion 11, and the limiting block 5 is located at the end away from the light emitting portion 11, so that the lamp body assembly 100 can be spliced ​​through the limiting block 5. In this embodiment, after the clamping block 32 is connected to the clamping hole 31, the first connecting portion 221 and the second connecting portion 12 are tightly attached. The second connecting portion 12 is elongated compared to the first connecting portion 221. At this time, the limiting block 5 is located below the clamping block 32 and at the portion of the second connecting portion 12 that is elongated relative to the first connecting portion 221, so that the second connecting portion 12 can be used to fix the lamp panel 2 while also being used to splice with other lamp body assemblies 100.

[0064] Furthermore, the stopper 5 can be a protruding block structure formed by the second connecting portion 12 protruding toward the direction of the lamp panel 2. In this embodiment, the stopper 5 is used to connect with the triangular keel 6 to realize the splicing of multiple lamp body assemblies 100 and to install the lamp body assembly 100 to the installation base.

[0065] Please refer to Figure 9 and Figure 10 When multiple lamp body assemblies 100 are spliced ​​together, the second connection portions 12 of adjacent lamp body assemblies 100 are closely attached to each other, the stoppers 5 protrude from the second connection portions 12 toward the lamp panel 2, and the stoppers 5 of adjacent lamp body assemblies 100 are collectively restrained within the triangular keel 6, thereby restraining the different lamp body assemblies 100 within the same triangular keel 6, thereby achieving splicing of the lamp body assemblies 100. Since the triangular keel 6 is also a commonly used material for suspended ceilings, the lamp body assemblies 100 can be installed on a suspended ceiling or other installation foundation while being spliced ​​together via the triangular keel 6.

[0066] It is understandable that this merely provides a splicing example and does not limit the splicing method of the lamp body assembly 100 .

[0067] Example 3:

[0068] This embodiment provides a lamp 200 based on the above embodiments.

[0069] like Figure 12As shown, the lamp 200 includes the lamp body assembly 100 of Example 2. The light-emitting assembly 4 and the driver assembly (not shown) are located within the housing 23 of the lamp body assembly 100. The light-emitting assembly 4 and the driver assembly are connected to the base plate 21 of the lamp panel 2. The light-emitting assembly 4 includes a plurality of substrates 41 and LED lamp beads 42 attached to the substrates 41. The substrates 41 are fixedly connected to the base plate 21. Light emitted by the light-emitting assembly 4 then passes through the housing 23 and is emitted from the light-emitting portion 11.

[0070] Since the light-emitting portion 11 and the second connecting portion 12 are integrally connected to form the light-emitting surface cover 1, and the light-emitting surface cover 1 and the lamp panel 2 are snap-fitted together, there is no need for an additional structure to connect the light-emitting portion 11 to the lamp panel 2. Therefore, when the light-emitting portion 11 covers the light-emitting opening 24, all light is emitted from the light-emitting portion 11 and is not blocked by the second connecting portion 12 of the light-emitting surface cover 1. At the same time, the first connecting portion 221 of the lamp panel 2 and the second connecting portion 12 of the light-emitting surface cover 1 are located outside the side panel 22 of the lamp panel 2, avoiding the accommodating space 23 and the light-emitting opening 24, and are located below the light-emitting portion 11. This effectively prevents the connection between the lamp panel 2 and the light-emitting surface cover 1 from blocking the light-emitting portion 11, making the light-emitting surface 111 of the lamp body assembly 100 have a borderless effect, thereby increasing the area of ​​the light-emitting surface 111 and facilitating seamless connection of the light-emitting surfaces 111 when multiple lamp body assemblies 100 are spliced, thereby optimizing the overall light-emitting effect.

[0071] The above content is merely an example and illustration of the structure of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these obvious alternative forms are all within the scope of protection of the present invention.
