[0002] At present, most of the side light emitting lamps on the market have the problems of uneven edge light emitting effect, particle feeling of lamp beads and dark circle, which will be more obvious on the frameless side light emitting lamp and will bring bad experience to users. Therefore, the scheme for solving the edge light emitting defects of the side light emitting lamp also emerges as the times require.

[0003] For example: Chinese patent publication No. CN219640121U, publication date September 5, 2023, the name of the utility model is a side light emitting panel lamp; the application discloses a lamp structure including a lamp shell, a light-transmitting lampshade and a light-emitting lamp strip, an installation cavity is formed in the inner side of the lamp shell, the light-emitting lamp strip is arranged on the inner wall of the installation cavity, the light-transmitting lampshade is arranged outside the lamp shell, and a diffusion ring plate is arranged between the light-transmitting lampshade and the light-emitting lamp strip. The scheme can make the light source emitted by the panel lamp more uniform, but in actual use, the light effect is still not good, and the brightness and comfort of the lamp body cannot achieve better experience. UTILITY MODEL CONTENTS

[0004] The utility model overcomes the uneven edge light emitting effect and dark circle of the existing frameless side light emitting lamp, and provides a frameless side light emitting lamp, which can solve the edge light emitting defect problem of the frameless side light emitting lamp and eliminate the problems of edge dark circle and uneven light emission.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme: a frameless side light emitting lamp, comprising a lamp body, the port of the lamp body is provided with a diffusion cover, a light guide plate is arranged in the lamp body, a diffusion ring is arranged between the light guide plate and the diffusion cover, and a lamp strip is arranged at the outer edge of the light guide plate and the inner edge of the lamp body. In this scheme, the lamp strip as a light source is arranged at the inner edge of the lamp body, and the light guide plate is arranged at the middle position of the lamp body. The light source generated by the lamp strip can be guided to the middle position of the lamp body through the light guide plate, and then emitted through the diffusion cover. In addition, the diffusion ring is arranged between the light guide plate and the diffusion cover, and the diffusion ring is arranged at the position close to the inner edge of the lamp body, which can greatly improve the light emitting effect of the edge of the lamp body and improve the uniformity and comfort of the light of the lamp body.

[0006] As a preferred, the light guide plate is provided with a reflective paper away from the diffusion cover, and the reflective paper is pressed between the light guide plate and the lamp body. The reflective paper is arranged at the position away from the diffusion cover of the light guide plate, which can improve the light guiding effect of the light guide plate, guide more light to the diffusion cover, and effectively improve the light brightness of the lamp.

[0007] Preferably, the light guide plate is evenly provided with annular micro-hole structures. The light guide plate is arranged with equidistant annular micro-holes in the middle, which can ensure the uniformity of the light-emitting surface of the light guide plate and improve the lighting effect.

[0008] Preferably, an annular groove is provided on the outer edge of the diffuser cover, and a first stopper is provided on the inner edge of the lamp body port, wherein the annular groove is adapted to engage with the first stopper. The annular groove on the diffuser cover can engage with the first stopper on the lamp body port, thereby facilitating assembly and disassembly of the diffuser cover.

[0009] Preferably, a retaining buckle is provided on the outer edge of the diffuser ring, and a second retaining portion is provided on the inner edge of the lamp body port, with the retaining buckle abutting against the second retaining portion. The retaining buckle on the diffuser ring can abut against the second retaining portion at the lamp body port, securing the diffuser ring while also providing a certain degree of positional retention for the light guide plate. Furthermore, the connection between the first retaining portion and the annular groove, and the second retaining portion and the retaining buckle, improves the sealing of the lamp body port, providing excellent waterproof and moisture-proof properties.

[0010] Preferably, the lamp body is further provided with an annular assembly groove, in which the light strip is embedded. Placing the light strip in the annular assembly groove at the edge of the lamp body can reduce the generation of light spots at the edge of the lamp.

[0011] Preferably, the light strip is an LED light strip. The light strip uses LED lights as the main body, which is convenient to select materials, has a longer service life, and has the advantages of energy saving and environmental protection.

[0012] Preferably, the light guide plate and the reflective paper are provided with fixing holes, and the light guide plate and the reflective paper are fixed to the lamp body via fixings. To ensure the position of the light guide plate and prevent it from tilting and causing uneven lighting effects, fixings are further used to secure the light guide plate. Increasing the fixing methods of the fixings can also effectively prevent internal heat generation from causing thermal expansion of the structure and causing partial detachment of the structure.

[0013] Preferably, the fixing member is a flat head screw. The fixing member adopts a flat head screw structure, which can reduce the uneven effect of the light.

[0014] Preferably, the fixing member is disposed in the light guide plate via a countersunk hole. After the fixing member is fixed, the head of the flat head screw is recessed in the plane of the light guide plate, so that when the diffuser cover is installed, the screw shadow will not be visible on the surface, and a uniform lighting effect can be achieved when the diffuser cover is lit.

[0023] The technical solution of the present invention will be further described below with reference to specific embodiments and in conjunction with the accompanying drawings.

[0024] Example 1: Figures 1 to 4 The illustrated side-emitting luminaire comprises a lamp body 1, which includes a lamp holder 1.1 and an annular cover 1.2. The annular cover 1.2 houses a light guide plate 3, a diffuser ring 4, a diffuser cover 2, and reflective paper 6. Specifically, the diffuser cover 2 is positioned at the end of the annular cover 1.2, and the diffuser ring 4, light guide plate 3, and reflective paper 6 are arranged in sequence toward the interior of the lamp body 1.

[0025] The outer end surface of the diffuser cover 2 is flush with the end of the annular cover 1.2 of the lamp body 1, forming a snap-fit ​​connection between the diffuser cover 2 and the annular cover 1.2. A diffuser ring 4 and a light guide plate 3 are arranged immediately inside the diffuser cover 2. One side of the light guide plate 3 is in contact with the lamp holder 1.1, while the other side of the light guide plate 3 abuts the diffuser ring 4. By snapping the diffuser ring 4 onto the annular cover 1.2, the internal structure of the lamp can be arranged relatively stably. The light guide plate 3 is a circular plate-shaped structure. An LED light strip 5 is arranged at the outer edge of the light guide plate 3. The LED light strip 5 is located at the side edge of the interior of the lamp body 1. When the light strip 5 emits light, it guides the light from the side edge of the lamp body 1 to the light guide plate 3. The light is then guided to the middle part of the lamp body 1 by the light guide plate 3. Under the diffusion effect of the diffuser ring 4, the light is emitted through the diffuser cover 2, thereby greatly improving the luminous effect at the edge of the lamp body 1 and enhancing the uniformity and comfort of the light from the lamp body 1.

[0026] In this embodiment, the lamp body 1 and the structure inside the lamp body 1 are circular or annular. The light guide plate 3 is a circular plate structure and is provided with a uniformly distributed annular micropore structure 7. The equidistant annular distribution of micropores 7 ensures the uniformity of the light-emitting surface of the light guide plate 3, thereby improving the lighting effect. Reflective paper 6 is also arranged between the light guide plate 3 and the lamp holder 1.1. The reflective paper 6 is clamped by the light guide plate 3 and the lamp holder 1.1 to prevent the reflective paper 6 from loosening or shifting in position, resulting in poor reflective effect. The reflective paper 6 is located on the side of the light guide plate 3 away from the diffuser ring 4 and diffuser cover 2. Therefore, when the light strip 5 is illuminated, the light is directed onto the light guide plate 3. The reflective paper 6 reflects the light on the light guide plate 3 toward the side where the diffuser ring 4 and diffuser cover 2 are located, concentrating more light on the diffuser cover 2 and improving the lighting effect of the lamp.

[0027] The diffuser cover 2 is an annular structure as a whole, and can cooperate with the annular cover 1.2 port of the lamp body 1. Specifically, an annular groove 8 structure is provided at the outer edge of the diffuser cover 2 and on the side of the diffuser cover 2 facing the inside of the lamp body 1, and a first limiting portion 9 is provided on the inner edge of the annular cover 1.2 of the lamp body 1. The first limiting portion 9 is an annular block structure. The annular groove 8 on the diffuser cover 2 and the first limiting portion 9 on the lamp body 1 are snap-connected together and are detachable. Guide slopes are provided on the side of the limiting groove 8 facing the inside of the lamp body 1 and on the side of the first limiting portion 9 facing the outside of the lamp body 1. In this way, when the diffuser cover 2 is installed on the lamp body 1, it will be simpler and more convenient. The diffuser cover 2 and the annular cover 1.2 on the lamp body 1 both have a certain elastic effect, so that when the diffuser cover 2 is installed, the rigidity of the diffuser cover 2 or the annular cover 1.2 will not be damaged.

[0028] Similarly, a limiting buckle 10 is provided at the outer edge of the diffusion ring 4. The diffusion ring 4 is a circular ring structure with a certain taper, with the taper facing the outside of the lamp body 1 (diffuser cover 2), which is conducive to the diffusion of light and eliminates the problems of dark circles on the edges and uneven lighting. A second limiting portion 11 is also provided at the inner edge of the annular cover 1.2 of the lamp body 1. The limiting buckle 10 is an annular step-shaped structure, and the second limiting portion 11 is an annular block structure. The second limiting portion 11 is provided near the inner side of the first limiting portion 9 of the lamp body 1 to facilitate the installation of the diffusion ring 4 inside the diffusion cover 2. The stepped surface of the limiting buckle 10 abuts against the second limiting portion 11 facing the inner side of the lamp body 1, pressing the diffusion ring 4 against the inner side of the lamp body 1, while the other side of the diffusion ring 4 abuts against the light guide plate 3. In this way, while fixing the diffusion ring 4, it also has the effect of fixing and limiting the light guide plate 3. It should be noted that guiding slopes are also provided on the side of the limiting buckle 10 facing the inside of the lamp body 1 and on the side of the second limiting part 11 facing the outside of the lamp body 1. The diffusion ring 4 also has a certain elastic effect, which is conducive to the installation and disassembly of the diffusion ring 4 on the lamp body 1.

[0029] Combined with the cooperation between the first limiting part 9 and the annular groove 8 on the lamp body 1, and the cooperation between the second limiting part 11 and the limiting buckle 10, a two-layer relatively sealed structure is formed at the port position of the annular cover 1.2 of the lamp body 1, which improves the sealing performance at the port of the lamp body 1 and has a better waterproof and moisture-proof effect.

[0030] An annular assembly groove 12 is further provided on the inner side of the annular cover 1.2 of the lamp body 1. The annular assembly groove 12 is arranged at a position close to the inner side of the lamp body 1 on the second limiting portion 11. The light strip 5 structure is provided in the annular assembly groove 12. Figure 3 As shown, the annular assembly groove 12 is a groove formed by the second stopper 11 and the inner side of the annular cover 1.2, which is used for assembling and securing the light strip 5. Furthermore, the light strip 5 is located at the outer edge of the light guide plate 3, with the light source of the light strip 5 facing toward the light guide plate 3, thereby directly directing light generated by the light source into the light guide plate 3. The radial dimension of the reflective paper 6 is slightly larger than that of the light baffle 3 and extends all the way to the side of the light strip 5's light source away from the diffusion ring 4, ensuring that as much light as possible is directed into the light guide plate 3.

[0031] Example 2: Figures 1 to 6 The illustrated side-emitting luminaire comprises a lamp body 1, which includes a lamp holder 1.1 and an annular cover 1.2. The annular cover 1.2 houses a light guide plate 3, a diffuser ring 4, a diffuser cover 2, and reflective paper 6. Specifically, the diffuser cover 2 is positioned at the end of the annular cover 1.2, and the diffuser ring 4, light guide plate 3, and reflective paper 6 are arranged in sequence toward the interior of the lamp body 1.

[0032] The outer end surface of the diffuser cover 2 is flush with the end of the annular cover 1.2 of the lamp body 1, forming a snap-fit ​​connection between the diffuser cover 2 and the annular cover 1.2. A diffuser ring 4 and a light guide plate 3 are arranged immediately inside the diffuser cover 2. One side of the light guide plate 3 is in contact with the lamp holder 1.1, while the other side of the light guide plate 3 abuts the diffuser ring 4. By snapping the diffuser ring 4 onto the annular cover 1.2, the internal structure of the lamp can be arranged relatively stably. The light guide plate 3 is a circular plate-shaped structure. An LED light strip 5 is arranged at the outer edge of the light guide plate 3. The LED light strip 5 is located at the side edge of the interior of the lamp body 1. When the light strip 5 emits light, it guides the light from the side edge of the lamp body 1 to the light guide plate 3. The light is then guided to the middle part of the lamp body 1 by the light guide plate 3. Under the diffusion effect of the diffuser ring 4, the light is emitted through the diffuser cover 2, thereby greatly improving the luminous effect at the edge of the lamp body 1 and enhancing the uniformity and comfort of the light from the lamp body 1.

[0033] In this embodiment, the lamp body 1 and the structure inside the lamp body 1 are circular or annular. The light guide plate 3 is a circular plate structure and is provided with a uniformly distributed annular micropore structure 7. The equidistant annular distribution of micropores 7 ensures the uniformity of the light-emitting surface of the light guide plate 3, thereby improving the lighting effect. Reflective paper 6 is also arranged between the light guide plate 3 and the lamp holder 1.1. The reflective paper 6 is clamped by the light guide plate 3 and the lamp holder 1.1 to prevent the reflective paper 6 from loosening or shifting in position, resulting in poor reflective effect. The reflective paper 6 is located on the side of the light guide plate 3 away from the diffuser ring 4 and diffuser cover 2. Therefore, when the light strip 5 is illuminated, the light is directed onto the light guide plate 3. The reflective paper 6 reflects the light on the light guide plate 3 toward the side where the diffuser ring 4 and diffuser cover 2 are located, concentrating more light on the diffuser cover 2 and improving the lighting effect of the lamp.

[0034] The diffuser cover 2 is an annular structure as a whole, and can cooperate with the annular cover 1.2 port of the lamp body 1. Specifically, an annular groove 8 structure is provided at the outer edge of the diffuser cover 2 and on the side of the diffuser cover 2 facing the inside of the lamp body 1, and a first limiting portion 9 is provided on the inner edge of the annular cover 1.2 of the lamp body 1. The first limiting portion 9 is an annular block structure. The annular groove 8 on the diffuser cover 2 and the first limiting portion 9 on the lamp body 1 are snap-connected together and are detachable. Guide slopes are provided on the side of the limiting groove 8 facing the inside of the lamp body 1 and on the side of the first limiting portion 9 facing the outside of the lamp body 1. In this way, when the diffuser cover 2 is installed on the lamp body 1, it will be simpler and more convenient. The diffuser cover 2 and the annular cover 1.2 on the lamp body 1 both have a certain elastic effect, so that when the diffuser cover 2 is installed, the rigidity of the diffuser cover 2 or the annular cover 1.2 will not be damaged.

[0035] Similarly, a limiting buckle 10 is provided at the outer edge of the diffusion ring 4. The diffusion ring 4 is a circular ring structure with a certain taper, with the taper facing the outside of the lamp body 1 (diffuser cover 2), which is conducive to the diffusion of light and eliminates the problems of dark circles on the edges and uneven lighting. A second limiting portion 11 is also provided at the inner edge of the annular cover 1.2 of the lamp body 1. The limiting buckle 10 is an annular step-shaped structure, and the second limiting portion 11 is an annular block structure. The second limiting portion 11 is provided near the inner side of the first limiting portion 9 of the lamp body 1 to facilitate the installation of the diffusion ring 4 inside the diffusion cover 2. The stepped surface of the limiting buckle 10 abuts against the second limiting portion 11 facing the inner side of the lamp body 1, pressing the diffusion ring 4 against the inner side of the lamp body 1, while the other side of the diffusion ring 4 abuts against the light guide plate 3. In this way, while fixing the diffusion ring 4, it also has the effect of fixing and limiting the light guide plate 3. It should be noted that guiding slopes are also provided on the side of the limiting buckle 10 facing the inside of the lamp body 1 and on the side of the second limiting part 11 facing the outside of the lamp body 1. The diffusion ring 4 also has a certain elastic effect, which is conducive to the installation and disassembly of the diffusion ring 4 on the lamp body 1.

[0036] Combined with the cooperation between the first limiting part 9 and the annular groove 8 on the lamp body 1, and the cooperation between the second limiting part 11 and the limiting buckle 10, a two-layer relatively sealed structure is formed at the port position of the annular cover 1.2 of the lamp body 1, which improves the sealing performance at the port of the lamp body 1 and has a better waterproof and moisture-proof effect.

[0037] An annular assembly groove 12 is further provided on the inner side of the annular cover 1.2 of the lamp body 1. The annular assembly groove 12 is arranged at a position close to the inner side of the lamp body 1 on the second limiting portion 11. The light strip 5 structure is provided in the annular assembly groove 12. Figure 3 As shown, the annular assembly groove 12 is a groove formed by the second stopper 11 and the inner side of the annular cover 1.2, which is used for assembling and securing the light strip 5. Furthermore, the light strip 5 is located at the outer edge of the light guide plate 3, with the light source of the light strip 5 facing toward the light guide plate 3, thereby directly directing light generated by the light source into the light guide plate 3. The radial dimension of the reflective paper 6 is slightly larger than that of the light baffle 3 and extends all the way to the side of the light strip 5's light source away from the diffusion ring 4, ensuring that as much light as possible is directed into the light guide plate 3.

[0038] Corresponding fixing holes 13 are provided on the light guide plate 3, reflective paper 6, and lamp holder 1.1. Fasteners 14 secure the light guide plate 3 and reflective paper 6 to the lamp holder 1.1, further ensuring the proper installation and stability of the light guide plate 3. Specifically, fasteners 14 are flat-head screws, and the fixing holes 13 on the light guide plate 3 are countersunk holes 15. When the flat-head screws are tightened into the lamp holder 1.1, the screw heads are located inside the light guide plate 3, not protruding from the surface. This ensures that the diffuser cover 2 is installed without casting a shadow from the screws, ensuring a uniform lighting effect when lit. The addition of fasteners 14 also effectively prevents internal heat expansion and partial detachment, improving the safety of the lamp. Different sizes of lamps can be fixed by adjusting the position and number of screws. When the height of the lamp is reduced, and the height between the flat surface of the light guide plate 3 and the luminous surface is less than 7 mm, the depth of the countersunk holes 15 can be adjusted to optimize the effect.
