[0017] As shown in Figures 1 to 5, a lamp 100 provided in the present application includes a lamp housing 10 and a lamp board 20 arranged in the lamp housing 10, a replaceable lighting effect component is provided on the lamp board 20, and the replaceable lighting effect component includes a cover plate 30, the cover plate 30 is arranged on the lamp board 20, and a light-transmitting area 301 and an opaque area 302 are provided on the cover plate 30.

[0018] The lamp 100 of the present application is described below through various embodiments.

[0019] In one embodiment, a diffusing agent is added to the light-transmitting material of the cover plate 30 so that the cover plate 30 can emit light uniformly under the illumination of the light source. A light-proof ink layer is provided on the upper surface of the cover plate 30 to form the light-proof area 302. The portion of the upper surface of the cover plate 30 where the ink layer is not provided is the light-transmitting area 301. In this embodiment, the light-transmitting area 301 is a linear light-transmitting area. As shown in FIG3 , the light-transmitting area 301 forms a linear pattern on the upper surface of the cover plate 30. The bottom surface of the cover plate is covered with the LED light source provided on the light board 20. The light of the LED light source passes through the body of the cover plate 30 and is emitted from the linear light-transmitting area 301. From a visual point of view, the portion of the linear light-transmitting area 301 can be seen to emit light, realizing the preset linear light-emitting lighting effect.

[0020] In another embodiment, the light-transmitting area 301 is a block-shaped light-transmitting area. As shown in Figure 2, the light-transmitting area 301 forms a block-shaped pattern on the upper surface of the cover plate 30. The bottom surface of the cover plate 30 covers the LED light source installed on the light board 20. The light from the LED light source passes through the main body of the cover plate 30 and is emitted from the block-shaped light-transmitting area 301. From a visual perspective, the block-shaped light-transmitting area 301 can be seen to emit light, achieving the preset block-shaped light effect.

[0021] In other embodiments, the light-transmitting area 301 can also be designed into more types of patterns according to specific needs to meet the needs of different lighting effects, so that the same lamp can achieve multiple lighting effects by replacing different cover plates 30.

[0022] In other embodiments, the lamp 100 further includes a light guide plate 40. Referring to FIG1 , the light guide plate 40 includes a light guide riser 42 and a light diffuser 43 disposed on top of the light guide riser 42 to create a suspended light effect. The cover plate 30 can have a variety of different shapes. In one embodiment, the cover plate 30 is a longitudinal sheet-like structure.

[0023] The cover plate 30 and the light guide plate 40 are assembled together. The two can be connected by any appropriate matching structure. For example, a first positioning structure 31 can be provided on the cover plate 30, and a second positioning structure 41 can be provided on the light guide plate 40. The cover plate 30 and the light guide plate 40 are fixed to each other by means of the cooperation of the first positioning structure 31 and the second positioning structure 41. Through the mutual snap-fitting effect of the first positioning structure and the second positioning structure, the light guide plate 40 can be fastened to the cover plate 30 conveniently and quickly to improve the assembly efficiency and speed of the two. Moreover, the snap-fitting is a detachable snap-fitting, so disassembly and replacement are also convenient. Specifically, the first positioning structure 31 includes a first positioning groove 32 provided on the cover plate 30. In this embodiment, the first positioning groove 32 is provided in the middle of the cover plate 30 and extends from one end to the other end in the longitudinal direction of the cover plate 30.

[0024] The length of the light guide plate 40 matches that of the cover plate 30. The second positioning structure 41 disposed therein includes a light guide riser 42 and ribs 44 formed at the bottom of the light guide riser 42 and extending from the bottom to both sides of the light guide riser 42. The light guide riser 42 can also be an elongated sheet-like structure with a width matching that of the first positioning slot 32. The light guide riser 42 can be inserted into the first positioning slot 32 on the cover plate 30.

[0025] The width of the rib 44 at the bottom of the light guide riser 42 is greater than the width of the light guide riser 42, and the height of the light guide riser 42 is greater than the thickness of the cover plate 30, so that the light guide riser 42 can pass through the first positioning groove 32 from the bottom of the cover plate 30, and then the light guide riser 42 can protrude from the top of the cover plate 30 until the rib 44 at the bottom of the light guide riser 42 abuts against the bottom of the cover plate 30. After the cover plate 30 and the light guide plate 40 are fixed to each other by means of the cooperation of the first positioning structure 31 and the second positioning structure 41, the rib 44 presses against the bottom of the cover plate 30, so that the light guide plate 40 cannot be separated from the cover plate 30.

[0026] With this mating structure, the cover plate and light guide plate can be assembled together quickly and conveniently by simply inserting the light guide plate through the first positioning slot and then placing the retaining edge against the bottom of the cover plate. In this embodiment, the retaining edge 44 and the light guide plate 40 are integrally formed, and together they form the light guide plate 40. The retaining edge 44 also serves to guide light.

[0027] In the present application, the light guide plate 42 is made of a transparent light guide material. After the light guide plate 40 and the cover plate 30 are fixed to each other, the light guide plate 42 at least partially protrudes from the upper surface of the cover plate 30. The light diffusion portion 43 provided on the top of the light guide plate 42 protrudes from the upper surface of the cover plate 30 as the light guide plate 42 protrudes from the upper surface of the cover plate 30. The interval between the light diffusion portion 43 and the upper surface of the cover plate 30 is the height of the portion of the light guide plate 42 protruding from the cover plate 30. The light diffusion portion 43 is made of light diffusion material. When the light emitted by the light source is transmitted through the transparent light guide plate 42 and coupled to the light diffusion portion 43, a floating luminous effect is formed in the light diffusion portion 43 on the upper surface of the cover plate 30 from a visual perspective, forming a special lighting effect. The combination of the light guide plate 42 and the cover plate 30 gives the lamp a more dreamy luminous effect, which can meet customers' demand for dreamy lighting effects.

[0028] In another embodiment, the first positioning groove 32 comprises two sections, one at each end of the cover plate 30 and extending to the middle of the cover plate 30, as shown in Figure 4. The two sections of the first positioning groove 32 each form a bent structure 320 in the middle of the cover plate 30. Corresponding to the structure of the first positioning groove 32, the light guide riser 42 and the retaining edge 44 are also formed in two sections. Corresponding to the bent structure 320 of the first positioning groove 32, the light guide riser 42 is provided with a light guide bent portion 420, and the retaining edge 44 is provided with a retaining edge bent portion. In this embodiment, the cover plate 30 and the light guide plate 40 can be more securely fixed to each other.

[0029] The lamp housing 10 is a rectangular strip-shaped structure with a groove 101 for accommodating the lamp board 20. The shape of the lamp board 20 matches the groove 101, and a plurality of LED light sources 201 are arranged on its upper surface. The LED light sources 201 are evenly arranged on the lamp board 20 to achieve the purpose of uniform light output from the lamp board 20.

[0030] The lamp 100 may also include a lamp board pressing piece 50, which abuts the lamp board 20 so as to fix the lamp board 20 in the lamp housing 10. As shown in Figure 1, the lamp board pressing piece 50 includes a plurality of pressing piece fixing holes 501, and a third positioning structure 502. The third positioning structure 502 includes a third positioning groove 52 opened on the lamp board pressing piece 50. The third positioning groove 52 matches the shape of the retaining edge 44 at the bottom of the light guide vertical plate 42. The lamp board pressing piece 50 is arranged between the lamp board 20 and the light guide plate 40, and the retaining edge 44 of the second positioning structure is arranged in the third positioning groove 52. By clamping the retaining edge 44 in the third positioning groove 52, the entire light guide plate 40 together with the cover plate 30 installed therewith is fixed on the lamp board pressing piece 50.

[0031] A row of LED light sources 202 is also provided on the light board 20 at a position corresponding to the third positioning groove 52 of the light board pressing piece 50 . When the light board pressing piece 50 is installed on the light board 20 , the row of LED light sources 202 is arranged at a position corresponding to the third positioning groove 52 .

[0032] The installation method of the lamp housing 10, lamp board 20, cover plate 30, light guide plate 40 and lamp board pressing piece 50 of the lamp 100 of the present application is as follows:

[0033] Place the lamp board 20 in the groove 101 of the lamp housing 10, and the LED light sources 201 of the lamp board 20 are all inside the lamp housing 10; place the lamp board pressing piece 50 on the lamp board 20, and align the third positioning groove 52 of the third positioning structure 502 with a row of LED light sources 202 on the lamp board 20, so that the light emitted by the row of LED light sources 202 is emitted from the third positioning groove 52.

[0034] The lamp board 20 is provided with a plurality of lamp board fixing holes 203 corresponding to the pressing member fixing holes 501 of the lamp board pressing member 50. Screws are passed through the pressing member fixing holes 501 and the lamp board fixing holes 203, and then fixed to the corresponding screw holes 12 provided at the bottom of the lamp housing 10, thereby fixing the lamp board 20 to the lamp housing 10 via the lamp board pressing member 50. By passing the screws through the lamp board pressing member 50 and locking it to the lamp housing 10, the tightening force of the screws can be evenly applied to the lamp board 20 across the entire surface of the lamp board pressing member 50, thereby preventing uneven pressure from causing local deformation of the lamp board 20.

[0035] After fixing the lamp board pressing piece 50 and the lamp board 20, the bottom of the light guide vertical plate 42 of the light guide plate 40 and the retaining edge 44 are placed into the third positioning groove 52 of the lamp board pressing piece 50, covering the row of LED light sources 202 under the third positioning groove 52 to guide the light of the row of LED light sources 202 to the light guide plate 40.

[0036] After the light guide plate 40 is secured, the first positioning groove 32 in the first positioning structure 31 of the cover plate 30 is aligned with the light guide riser 42 of the light guide plate 40. The light guide riser 42 passes through the first positioning groove 32 from the bottom of the cover plate 30 and protrudes from the top of the cover plate 30 until the retaining edge 44 at the bottom of the light guide riser 42 presses against the bottom of the cover plate 30. The first, second, and third positioning structures cooperate to secure the cover plate 30 to the light board press 50. The first and second positioning structures enable a quick and removable connection between the cover plate 30 and the light guide plate 40. The second positioning structure 41 then cooperates with the third positioning structure 502 to secure the light guide plate 40 to the light board press 50, thereby indirectly securing the cover plate 30 to the light board 20.

[0037] From the perspective of the lighting effect of the lamp 100, the light emitted by the row of LED light sources 202 under the third positioning groove 52 is conducted through the transparent light guide plate 42 and coupled to the light diffusion part 43, forming a luminous effect suspended on the upper surface of the cover plate 30.

[0038] Furthermore, after the cover plate 30 and the light guide riser 42 are secured together, the protruding portion of the light guide riser 42 divides the majority of the upper surface of the cover plate 30 into two left and right sections. The light panel 20 includes two rows of LED light sources, each corresponding to the left and right sections of the cover plate 30. Light from the two rows of LED light sources 201 illuminates the cover plate 30 and is emitted from the light-transmitting area 301 of the cover plate 30, creating a predetermined lighting effect for the cover plate 30 through the pattern of the light-transmitting area 301.

[0039] A through-hole 34 is also provided on the cover plate 30; screws are passed through the through-hole 34 and screwed into the screw holes 12 of the lamp housing 10, thereby fixing the cover plate 30 on the lamp housing 10 to complete the installation of the lamp housing 10, the lamp board 20, the cover plate 30, the light guide plate 40 and the lamp board pressing piece 50. The use of screw fastening can provide a more reliable fastening effect and is easy to use. For example, the user can quickly achieve the purpose of fastening or disassembly with an electric screwdriver. After the cover plate 30 is installed, it covers the lamp board 20, the lamp board pressing piece 50 and part of the light guide plate 40. Since the cover plate 30 is arranged in the lamp housing 10, a closed space can be further formed by the buckling between the lamp housing 10 and an external cover body such as a lampshade, thereby protecting the cover plate 30.

[0040] In this application, the cover plate 30 is made of a light-conducting material. Different cover plates 30 can be configured to produce different lighting effects. As one of the interchangeable lighting effect components, the cover plate 30 can be removed and replaced with a different lighting effect by simply removing the screws on the cover plate 30. Traditional lamps require replacing the entire lamp to adapt to the different LED light source effects. The lamp provided by this application allows users to change the lighting effect by simply replacing the cover plate 30, while retaining the original lamp housing 10, lamp panel 20, lamp panel pressure piece 50, and light guide plate 40. This significantly reduces costs for the customer. Furthermore, the design of the lamp structure makes it very convenient to remove and install the cover plate 30, allowing ordinary users to do this themselves. In other words, the lamp provided by this application can include multiple cover plates, each of which can be selectively positioned on the lamp panel.

[0041] In addition, the light guide plate 40 can be made of a transparent light-guiding material or a colored light guide plate. When the user needs to change the lighting effect of the lamp, the cover plate 30 can be removed and the light guide plate 40 can be directly removed and replaced with a light guide plate 40 of a different color. Because the light panel pressing piece 50 is provided with a third positioning groove 52, the light guide plate 40 can be directly placed and removed according to the third positioning groove 52, which is very convenient and quick to operate.

[0042] In other embodiments, the lamp board 20 or the lamp board pressing piece 50 or the cover plate 30 may be fixed to the lamp housing 10 by other fixing methods, not limited to the fixing method of screws.

[0043] The lamp 100 includes a lampshade 60, as shown in FIG5 . The lampshade 60 is snapped onto the lamp housing 10 to enclose the above-mentioned replaceable lighting effect component in the lampshade 60 inside the lamp housing 10. The lampshade 60 can be transparent or made of a non-transparent light-transmitting material. The lampshade 60 is snapped onto and fixed to the lamp housing 10 by magnetic attraction. This magnetic fixing method avoids the need to open screw holes and use screws on the component, so the structure is simpler. Through the cooperation of the lampshade 60 and the lamp housing 10, an internal space for accommodating the replaceable lighting effect component is formed, thereby providing a certain degree of protection for it.

[0044] The present application provides a lamp 100 that, by providing a replaceable lighting effect component cover plate 30 on a lamp panel 20 and a light guide plate 40 provided on the cover plate 20, allows a user to change the lighting effect of the lamp 100 by simply replacing the cover plate 20. Furthermore, by providing a light-transmitting area 301 and an opaque area 302 on the cover plate 30, and by arranging the pattern of the light-transmitting area 301, different cover plates 30 can have different lighting effects. When a user wants to change the lighting effect of the lamp, they only need to replace the cover plate 30.

[0045] In addition, by providing a first positioning structure 31 on the cover plate 30 and a second positioning structure 41 on the light guide plate 40, the cover plate 30 and the light guide plate 40 are fixed to each other by means of the cooperation of the first and second positioning structures, and by the third positioning structure 502 of the lamp board pressing piece 50 cooperating with the first and second positioning structures, the operation of installing and fixing the cover plate 30 to the lamp board 20 or removing the cover plate 30 from the lamp 100 becomes simpler and more convenient, so that the user can easily achieve the purpose of replacing the lighting effect of the lamp 100.
