[0038] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in detail below in combination with the drawings and specific embodiments.

[0039] Here, it needs to be explained that, in order to avoid being obscured by unnecessary details, only the structures and / or processing steps closely related to the scheme of the utility model are shown in the drawings, and other details not closely related to the utility model are omitted.

[0040] In addition, it also needs to be explained that the term "comprises", "includes" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent to such process, method, article or equipment.

[0041] Please refer to Figures 1 to 13 As shown in the figure, the lamp 200 can be a sky lamp, a ceiling lamp and other lighting products, which is not limited here. The lamp 200 includes a shell 140 and a surface light emitting illumination device 110 and a side light emitting illumination device 100 arranged in the shell 140. The shell 140 includes a top wall 1401 and a side frame 1 extending away from the top wall 1401, and a light outlet is formed between the top wall 1401 and the side frame 1.

[0042] Please refer to Figures 1 to 3 As shown in the figure, the lamp 200 has a mounting side 120 facing the mounting base and an illumination side 130 arranged opposite to the mounting side 120. The surface light emitting illumination device 110 is arranged close to the mounting side 120 and is fixedly connected with the top wall 1401. The side light emitting illumination device 100 is arranged close to the illumination side 130, and the surface light emitting illumination device 110 is located above the side light emitting illumination device 100. The surface light emitting illumination device 110 is used for main lighting. The side light emitting illumination device 100 is arranged around the surface light emitting illumination device 110 to provide ambient light for auxiliary lighting.

[0043] The surface light emitting illumination device 110 comprises a main light source assembly 1101, a main light emitting surface 1102 and a light emitting plate 1103 arranged on the main light emitting surface 1102. The main light source assembly 1101 is fixed on the top wall 1401, and the main light source assembly 1101 is provided with a light source part which emits light towards the illumination side 130. The main light emitting surface 1102 is located on the light emitting route of the main light source assembly 1101, and the light emitted by the light source part is emitted from the main light emitting surface 1102.

[0044] As shown in Figures 3 to 4 , the side light emitting illumination device 100 comprises a side frame 1, a light source 2, a light guide part 3 and a reflecting part 4. The side frame 1 surrounds the surface light emitting illumination device 110. In the embodiment, the light source 2 is a linear light source. The light source 2 is fixed on the side frame 1 and emits light towards the illumination side 130. The light guide part 3 is fixed on the side frame 1 and is located on the side of the light source 2 away from the mounting side 120. That is, the light guide part 3 is located on the light emitting direction of the light source 2. The reflecting part 4 is arranged between the light guide part 3 and the side frame 1 and is used for reflecting light.

[0045] In the embodiment, the side frame 1 is a ring type, as shown in Figure 1 and Figure 5 In other embodiments, the side frame 1 can also be a square type, as shown in Figure 11 .

[0046] As shown in Figures 4 to 7 , the side frame 1 comprises a light source fixing wall 11, a side wall 12, a bottom wall 13 and an extension wall 14. The side wall 12 is fixed below the top wall 1401 and extends towards the illumination side 130 from the top. The bottom wall 13 is arranged at the end of the side wall 12 away from the mounting side 120. The bottom wall 13 is provided with a resisting wall 131 which extends beyond the side wall 12 towards the light guide part 3. The extension wall 14 is fixed on the side of the light guide part 3 away from the side wall 12, and the extension wall 14 extends in the same direction as the side wall 12, i.e. in the direction from the mounting side 120 to the illumination side 130. The extension wall 14 extends towards the side wall 12 to form the light source fixing wall 11. A receiving structure is formed between the resisting wall 131 and the extension wall 14 for bearing and fixing the light guide part 3.

[0047] The light source 2 is fixed on the side of the light source fixing wall 11 towards the bottom wall 13, and the light source 2 and the light guide part 3 are both ring structures, and the side frame 1 surrounds the light source 2.

[0048] As shown in Figure 4 , the light guide part 3 is arranged on the light emitting route of the light source 2 and extends in the same direction as the side wall 12. The light guide part 3 abuts against the resisting wall 131.

[0049] As shown in Figures 1 to 8As shown, the light guide 3 includes a light inlet surface 31, a light control surface 32, a first light outlet surface 33, a first notch 34, and a second notch 37.

[0050] The first notch 34 and the second notch 37 are arranged on opposite sides of the light guide 3. The extension wall 14 abuts the first notch 34 and can shield the light source 2 from being directly seen by the human eye. This arrangement can avoid direct exposure of the light source 2 to the line of sight, reduce visual interference and discomfort, and make the light emitted by the lamp 200 softer and more uniform, thereby improving the visual comfort of the user. The abutting wall 131 abuts the second notch 37 and fixes the light guide 3 in the receiving structure. The abutting wall 131 and the extension wall 14 limit the light guide 3, which helps to prevent the light guide 3 from shifting or shaking during use and improves the structural stability of the entire side light emitting illumination device 100. The abutting wall 131 abuts the second notch 37, which makes the light guide 3 easier to align with the bottom wall 13 and fix during installation, simplifies the installation process, and improves the installation efficiency.

[0051] The light inlet surface 31 is arranged on the side of the light guide 3 close to the light source fixing wall 11 and faces the light source 2. The light inlet surface 31 is arranged opposite the light source 2, so that the light emitted by the light source 2 enters the light guide 3 through the light inlet surface 31. The light control surface 32 is arranged opposite the light inlet surface 31. Specifically, the light control surface 32 is arranged on the side of the light guide 3 close to the side wall 12 and opposite the side wall 12. The first light outlet surface 33 is arranged on the side of the light guide 3 away from the side wall 12. The first light outlet surface 33 is connected to the main light outlet surface 1102 and extends beyond the main light outlet surface 1102 in the direction of the illumination side 130.

[0052] Please refer to Figure 4 and Figure 8 As shown, the first notch 34 is provided with a light outlet plate 1103, which is located between the extension wall 14 and the first notch 34. Some of the light emitted by the main light source assembly 1101 mixes with the light emitted by the light source 2, forming a mixed light effect.

[0053] Please refer to Figure 9 As the first light outlet surface 33 of the light guide 3 is perpendicular to the light inlet surface 31, the angle of incidence and the angle of refraction of the light rays entering the light inlet surface 31 and propagating to the first light outlet surface 33 are mutually complementary. Therefore, these light rays cannot be emitted by the first light outlet surface 33 but are totally reflected by the first light outlet surface 33 to the light control surface 32. The light control surface 32 is parallel to the first light outlet surface 33, so the light rays cannot be emitted by the first light outlet surface 33 but are reflected back and forth between the first light outlet surface 33 and the light control surface 32 until reaching the end surface of the light guide 3 away from the light inlet surface 31.

[0054] Please refer to Figure 10To avoid the above situation, at least one first light control microstructure 321 is arranged on the light control surface 32. Among the light entering the light guide 3, at least part of the light is reflected by the first light control microstructure 321, and at least part of the light is refracted by the first light control microstructure 321. The light reflected by the first light control microstructure 321 is emitted from the first light exit surface 33. That is, the first light control microstructure 321 can break the total reflection on the light control surface 32, so that the light entering from the light entrance surface 31 is diffusely reflected after reaching the light control surface 32, so that part of the light is emitted from the light control surface 32 to the side wall 12. At the same time, the light that is totally reflected by the first light exit surface 33 can be partially or totally emitted from the first light exit surface 33, avoiding the total reflection between the light control surface 32 and the first light exit surface 33.

[0055] In some embodiments, one first light control microstructure 321 is arranged on the light control surface 32. In other embodiments, a plurality of first light control microstructures 321 are arranged on the light control surface 32, which can make more light refract through the first light control microstructure 321 to improve the light control effect.

[0056] Please refer to Figure 10 In some embodiments, the first light control microstructure 321 is a knurling structure arranged on the light control surface 32, that is, a micro concave-convex structure is formed on the surface of the light control surface 32, so that the light is no longer a simple plane reflection process when it hits the light control surface 32. The concave-convex structure causes the light to be reflected and refracted multiple times on the light control surface 32, changing the propagation direction of the light, thereby reducing the reflection angle of the light on the light control surface 32. When the reflection angle of part of the light is reduced to below the critical angle, the light is emitted from the first light exit surface 33; instead of being totally reflected at the first light exit surface 33 and reflected back onto the light control surface 32. In this way, the first light control microstructure 321 effectively controls the propagation path of the light, so that part of the light can be emitted from the first light exit surface 33 in a predetermined direction.

[0057] In other embodiments, the first light control microstructure 321 is a laser dotting on the light control surface 32 to form a micro point texture, so that the light is reflected and refracted multiple times on the light control surface 32, changing the propagation direction of the light, so that when the reflection angle of part of the light is reduced to below the critical angle, the total reflection condition is broken, and the light is emitted from the first light exit surface 33. Because the point texture formed by laser dotting can break the total reflection condition, part of the light that would otherwise be lost due to total reflection can be emitted from the first light exit surface 33. This not only improves the utilization efficiency of the light, but also enhances the light output rate of the side-emitting illumination device 100, so that a brighter and more uniform illumination effect can be obtained under the same light source.

[0058] In some embodiments, the first light control microstructure 321 is a sandblasting structure on the light control surface 32, which destroys the smooth surface of the light control surface 32, so that the light rays are scattered or refracted when exiting, and are no longer concentrated in one direction or angle as in the traditional smooth surface, but are dispersed in multiple directions, thereby avoiding the concentration of light rays in one direction or area. In this way, the uniform distribution of light rays is improved, and the lighting effect and visual comfort are improved.

[0059] Please refer to Figure 4 and Figure 8 In some preferred embodiments, the first distance between the outer surface of the extension wall 14 and the side wall 12, and the second distance between the first light exit surface 33 and the side wall 12 are provided, and the second distance is greater than or equal to the first distance. In this way, the optical path of the light rays emitted from the first light exit surface 33 is effectively extended, which is beneficial to the uniform distribution of light rays.

[0060] The light guide 3 further comprises a second light exit surface 38 opposite to the light entrance surface 31, and the second light exit surface 38 is perpendicular to the extension direction of the light guide 3. In the direction perpendicular to the extension direction of the light guide 3, the ratio of the width of the second light exit surface 38 to the width of the second gap 37 is greater than 2, which can increase the light exit area, so that more light rays are emitted from the second light exit surface 38.

[0061] The light guide 3 is made of full transparent material, so that the LED lamp beads can be seen from the second light exit surface 38, and the light source 2 has a granular feeling. In order to eliminate the granular feeling and glare problem, a second light control microstructure (not shown) is provided on the second light exit surface 38, and the second light control microstructure is configured to realize the diffuse scattering of light rays when the light rays are emitted from the second light exit surface 38. That is, the light rays will change their original optical path after passing through the second light control microstructure, and diffuse scattering occurs, so that the light rays are more uniformly scattered or refracted, avoiding the direct entry of light rays into the human eye and causing a dazzling feeling. Further, the granular feeling and glare problem caused by direct illumination of light rays are reduced, and a softer and more uniform lighting effect is provided.

[0062] In some embodiments, the second light control microstructure and the first light control microstructure 321 have the same structure. In other embodiments, the second light control microstructure can also have a structure different from the first light control microstructure 321, that is, the second light control microstructure can be any structure that can realize diffuse scattering of light rays, which is not limited here.

[0063] The first gap 34 divides the light guide 3 into a first part 35 and a second part 36 arranged in an upper and lower manner, and the first part 35 and the second part 36 are coplanar on the side facing the side wall 12. The first part 35 is clamped between the extension wall 14 and the side wall 12, and the second part 36 is exposed to the extension wall 14. The cross-sectional area of the first part 35 is smaller than that of the second part 36, and the first light exit surface 33 is arranged on the side of the second part 36 away from the side wall 12.

[0064] The light rays emitted from the junction of the first gap 34 and the extending wall 14 are concentrated, which is easy to produce bright lines. Preferably, the width of the first gap 34 is greater than the width of the extending wall 14 in the direction perpendicular to the extending direction of the light guide 3. That is, the distance between the first gap 34 and the light control surface 32 is greater than the distance between the extending wall 14 and the light control surface 32. In this way, the optical path of the light rays emitted from the junction of the first gap 34 and the extending wall 14 is effectively extended, avoiding the bright line phenomenon caused by the concentration of light rays, thereby improving the softness and comfort of the overall lighting effect.

[0065] In some preferred embodiments, the first light control microstructure 321 has a highest position on the light control surface 32, the highest position has a first height from the light source fixing wall 11, and the first gap 34 has a second height from the light source fixing wall 11, the first height is less than the second height. That is, the first light control microstructure 321 is not only arranged on the second part 36, but also arranged on part of the first part 35, so that the light rays are more uniformly distributed in the first part 35, avoiding the concentration of light rays in the junction area of the first gap 34 and the extending wall 14, and reducing or eliminating the generation of bright lines.

[0066] Please refer to Figures 11 to 13 In some preferred embodiments, a plurality of micro-ridge structures 331 are arranged on the first light exit surface 33, the plurality of micro-ridge structures 331 are parallel and spaced apart, and each vertically extends along the first light exit surface 33. In this way, the design of the micro-ridge structure 331 can adjust the angle of the light rays emitted from the first light exit surface 33, weaken or concentrate the light rays that may have been emitted at a large angle to the center small angle area, thereby increasing the effective light intensity of the center area and reducing the glare phenomenon of the edge area, making the light distribution more uniform and comfortable. By finely adjusting the exit angle of the light rays, the micro-ridge structure 331 effectively avoids the bright and dark spots and shadows caused by uneven scattering of light, improving the uniformity and clarity of the overall lighting.

[0067] The parallel and spaced arrangement of the micro-ridge structure 331 makes the first light exit surface 33 present an orderly and beautiful texture effect. In addition, by optimizing the exit angle of the light rays, the micro-ridge structure 331 reduces the ineffective scattering and loss of light, and improves the utilization rate of light energy. Under the premise of maintaining the same lighting effect, the power consumption of the light source can be reduced, thereby saving energy and operating costs.

[0068] Please refer to Figures 4 to 10As shown, in some embodiments, the color of the side frame 1 is dark, or the structure of the side frame 1 is rough, and the light emitted by the light control surface 32 is incident on the dark or rough side wall 12, which absorbs the light. In order to make the most of the light incident on the side wall 12 from the light control surface 32, a reflecting member 4 is arranged between the light control surface 32 and the side wall 12, which can reflect more light incident on the side wall 12 into the light guide 3, thereby improving the light efficiency.

[0069] The light emitted by the light source 2 enters the light guide 3 from the light-incident surface 31, and at least part of the light is reflected by the first light control microstructure 321 and then emitted from the first light-emitting surface 33. Moreover, at least part of the light is refracted by the first light control microstructure 321 and then emitted onto the reflecting member 4, and then reflected by the reflecting member 4 and re-entered into the light guide 3 from the light control surface 32, and then emitted from the first light-emitting surface 33.

[0070] In some embodiments, the reflecting member 4 is a reflecting paper, and the reflecting paper is attached to the side of the light control surface 32 away from the first light-emitting surface 33. In this way, the installation process of the reflecting paper is simple, which can save production costs and also reduce the weight of the lamp 200. By the reflecting paper, most of the light emitted by the light control surface 32 is reflected back into the light guide 3, and in this process, the light reflected by the reflecting paper is diffused by the light control surface 32 and then emitted from the first light-emitting surface 33. In this way, not only the distribution of light is optimized, but also a similar light efficiency enhancement effect as setting a diffusion plate on the side of the first light-emitting surface 33 is achieved. That is, in this embodiment, no additional diffusion plate is needed, and the soft light effect is achieved by the reflecting member 4, which further simplifies the structure and saves costs.

[0071] In some preferred embodiments, the reflecting member 4 is arranged corresponding to the first light control microstructure 321. In the extension direction of the light guide 3, the height of the reflecting member 4 is greater than or equal to the height of the first light control microstructure 321, so that the reflecting member 4 can reflect most of the light emitted by the light control surface 32 back into the light guide 3, thereby minimizing light waste.

[0072] In summary, the utility model discloses at least one first light control microstructure 321 is provided on the light control surface 32, makes the parallel incident light that enters the light guide piece 3 reflection on the first light control microstructure 321, and the reflected light is shot in different directions irregularly, that is, the light occurs diffuse reflection on the light control surface 32, makes the light distribution more uniform. On the one hand, the reflection angle of light after passing through the first light control microstructure 321 is smaller than the reflection angle of light after passing through the smooth light control surface 32, so that more light is shot from the first light exit surface 33 after being reflected by the first light control microstructure 321. On the other hand, the lamp 200 of the utility model utilizes the first light control microstructure 321 to reflect and scatter the light emitted by the light source 2, so that the light is uniformly shot from the first light exit surface 33 at different angles, converts linear light into area light, expands the light emitting area, and enhances the uniformity and softness of the light, reduces the glare, and improves the visual comfort. Compared with the prior art, the lamp 200 of the utility model does not need to set the diffusion plate in the conventional side-in type LED flat lamp, and can obtain soft light effect, and the overall structure is simple. At the same time, the diffusion plate avoids the loss of light, and effectively improves the overall light efficiency.

[0073] The above embodiments are only used to illustrate the technical solutions of the utility model and not limit, although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the utility model.
