Description

Technical Field

[0001] The utility model relates to the technical field of lighting, and particularly relates to a lighting fixture. Background Art

[0002] In the field of lighting design, square lighting fixtures are favored for their simple lines and wide application scenarios. However, when achieving lateral light output, most light sources are vertically arranged, and the light directly shines towards the side, which may cause glare or dark areas.

[0003] Secondly, at the corner of the lighting fixture, a light guide body spliced at 90° is often required to achieve continuous light propagation. The splicing of the light guide body at the corner often results in a significant difference in the distance between the material and the light source on both sides of the corner. This distance difference causes the light to be scattered and absorbed to different degrees when passing through the corner, and thus an obvious non-uniform light effect appears on the light output surface at the corner. This non-uniformity not only affects the overall aesthetics of the lighting fixture, but may also cause uneven light distribution in the lighting area, affecting the lighting effect and the visual experience of users. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a lighting fixture with uniform light output.

[0005] To achieve the above purpose, the utility model provides a lighting fixture for installation on an installation base, comprising:

[0039] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Here, it should be noted that in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, while other details less relevant to the present utility model are omitted.

[0041] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0042] Please refer to Figures 1 to 6 As shown, the lamp 100 of the embodiment of the present utility model is presented. The lamp 100 is a square lamp, and the lamp head 130 is connected to the ceiling box 120 through a suspension wire 110, thereby installing the entire lamp 100 on an installation base (such as a ceiling). The lamp 100 includes a side light source assembly 300 and a main light source assembly 700. The side light source assembly 300 provides a soft lighting effect for the surrounding environment by lateral light emission, and the main light source assembly 700 provides bright direct lighting. Through the combined use of the side light source assembly 300 and the main light source assembly 700, a multi-dimensional lighting effect of the lamp 100 is achieved, providing users with an efficient and uniform lighting experience.

[0043] The lamp 100 includes an outer frame 200. The outer frame 200 serves as the main frame of the lamp 100 and includes an outer side wall 210 extending in a direction away from the installation base. Please refer to Figures 2 to 4 As shown, a receiving groove 220 is provided on the outer side wall 210. The receiving groove 220 includes a notch 2201 on the outer side wall 210 and a groove wall 2202 connected to the notch 2201.

[0044] Please refer to Figure 3 As shown, the side light source assembly 300 is disposed in the receiving groove 220 and includes a light source substrate 310 disposed on the groove wall 2202 and a first light emitting member 320 disposed on the light source substrate 310. The receiving groove 220 not only provides an installation space for the side light source assembly 300 but also effectively protects the side light source assembly 300 through the groove wall 2202, preventing external factors such as dust and moisture from eroding and damaging the side light source assembly 300. The combination of the side light source assembly 300 and the receiving groove 220 makes the overall structure of the lamp 100 more compact, effectively utilizing the space inside the lamp 100, not only reducing the volume of the lamp 100 but also making the appearance of the lamp 100 more concise and beautiful.

[0045] The light source substrate 310 includes a mounting surface 3101, and the plane where the mounting surface 3101 is located is perpendicular to the plane where the outer side wall 210 is located. The first light-emitting element 320 is disposed on the side of the light source substrate 310 away from the mounting surface 3101 and emits light in a direction away from the mounting surface 3101. In this embodiment, the first light-emitting element 320 emits light in the direction towards the mounting base. In other embodiments, the first light-emitting element 320 may also emit light in the direction away from the mounting base, and the present utility model does not limit this.

[0046] The lamp 100 further includes a light distribution member 400 disposed in the receiving groove 220. The receiving groove 220 is provided with a first snap portion 2203, and the light distribution member 400 is correspondingly provided with a second snap portion 410. The light distribution member 400 is fixed to the receiving groove 220 through the first snap portion 2203 and the second snap portion 410.

[0047] In this embodiment, the first snap portion 2203 is a groove, and the second snap portion 410 is a protrusion. The light distribution member 400 is made of a flexible material (such as silicone or PVC, etc.). When installing the light distribution member 400, the light distribution member 400 is pushed into the receiving groove 220 from the slot opening 2201, so that the protrusion is snapped into the groove, thereby fixing the light distribution member 400 in the receiving groove 220. In other embodiments, the first snap portion 2203 may also be set as a protrusion, and the second snap portion 410 may be set as a groove. Further, the connection between the first snap portion 2203 and the second snap portion 410 may also be in other forms, including but not limited to the connection between a hook and a slot, and the present utility model does not limit this.

[0048] Please refer to Figure 3 As shown, the light distribution member 400 includes a first portion 420 and a second portion 430. The first portion 420 is disposed close to the slot opening 2201 and the first light-emitting element 320.

[0049] The light distribution member 400 is located in the light-emitting path of the first light-emitting element 320, and it includes a first light-incident surface 440, a first reflection surface 450, and a first light-emitting surface 460. Among them, both the first light-incident surface 440 and the first light-emitting surface 460 are disposed on the first portion 420, and the first reflection surface 450 is the interface between the first portion 420 and the second portion 430.

[0050] The first light incident surface 440 is arranged facing the first light emitting element 320, ensuring that the light emitted by the first light emitting element 320 can efficiently enter the interior of the light distribution element 400. Specifically, an avoidance groove 4201 is provided at the position of the first part 420 corresponding to the first light emitting element 320 to ensure that there is no position conflict between the first light emitting element 320 and the light distribution element 400. Moreover, on the plane where the light source substrate 310 is located, the projection range of the first light incident surface 440 covers the projection range of the first light emitting element 320, which means that all the light emitted by the first light emitting element 320 can be effectively received by the first light incident surface 440, enabling more light to reach the target illumination area and helping to improve the illumination effect of the lamp 100.

[0051] The first reflecting surface 450 is arranged in the receiving groove 220 and can effectively reflect light in a predetermined direction, thereby achieving precise control of the light. The first reflecting surface 450 can reduce the scattering and loss of light inside the light distribution element 400 and improve the light efficiency. Moreover, on the plane where the light source substrate 310 is located, the projection range of the first reflecting surface 450 covers the projection range of the first light emitting element 320, and the projection range of the first reflecting surface 450 on the first light emitting surface 460 of the side light source assembly 300 covers the light emitting area of the side light source assembly 300. That is to say, all the light incident from the first light emitting element 320 into the light distribution element 400 can be fully received by the first reflecting surface 450 and effectively reflected, reducing the loss of light during the transmission process.

[0052] In this embodiment, the first reflecting surface 450 is an arc-shaped curved surface, and the arc-shaped curved surface protrudes in a direction away from the first light emitting element 320. This shape design enables the light reflected from the first reflecting surface 450 to be directionally reflected at a predetermined angle and direction. At the same time, the arc-shaped curved surface can produce a more uniform and soft illumination effect, reducing glare and shadow areas.

[0053] In other embodiments, the first reflecting surface 450 can also be a plane, which can be specifically selected according to user requirements.

[0054] The first light emitting surface 460 is arranged at the notch 2201. The light emitted by the first light emitting element 320 enters the light distribution element 400 through the first light incident surface 440, and at least part of it passes through the first light emitting surface 460 after passing through the first reflecting surface 450, forming uniformly distributed light in the illumination area and reducing light spots and dark areas.

[0055] In this embodiment, the first part 420 and the second part 430 are integrally formed, significantly enhancing the structural stability of the light distribution element 400 and reducing the risk of light leakage or structural damage caused by insecure connection between components. This design enables the light distribution element 400 to withstand greater external force impacts and extends the service life of the lamp 100.

[0056] In other embodiments, the first part 420 and the second part 430 can also be separately provided, and different materials, colors, shapes and sizes can be selected for combination according to actual needs. The present utility model does not limit this.

[0057] In this embodiment, the first part 420 and the second part 430 have different colors. The first part 420 is made of a light-transmitting material or a semi-light-transmitting material, allowing light to pass through and producing a soft scattering effect, providing a uniform and comfortable light distribution in the lighting area. The second part 430 is made of an opaque and highly reflective material, which can effectively reflect light and direct the light to a predetermined direction, thereby enhancing the lighting effect.

[0058] The outer side wall 210 includes a contact surface 2101 that contacts the light distribution member 400, an outer side surface 2102 that faces away from the receiving groove 220, and an inclined light guiding surface 2103 that connects the contact surface 2101 and the outer side surface 2102. The inclined light guiding surface 2103 can guide the light from the light distribution member 400 to the outer side wall 210 and diffuse along the inclined light guiding surface 2103. The angle between the inclined light guiding surface 2103 and the contact surface 2101 is an obtuse angle, which expands the light output angle. The light will gradually disperse during propagation, helping to achieve a more uniform light distribution, and the light can cover a wider area, expanding the lighting range of the lamp 100 and meeting the lighting needs in different scenarios.

[0059] The outer frame 200 has a polygonal structure. In this embodiment, the outer frame 200 is a quadrilateral. In other embodiments, the outer frame 200 can also be a triangle or other polygons.

[0060] The outer frame 200 is formed by connecting a plurality of frames. The light source substrate 310 located at the top corner position of the outer frame 200 is correspondingly provided with a first light emitting member 320 at the edge near the top corner position, so that the light output at the top corner position of the outer frame 200 is uniform.

[0061] In this embodiment, please refer to Figures 5 to 6 As shown, the outer frame 200 includes a first side 230 and a second side 240 that are adjacent to each other. The side light source assembly 300 includes a first side light source assembly 330 provided on the first side 230 and a second side light source assembly 340 provided on the second side 240.

[0062] Among them, the first light emitting member 320 in the first side light source assembly 330 extends to the end of the first side 230, and the short side of the second side light source assembly 340 is arranged close to the long side of the first side light source assembly 330. Such a design enables the first side light source assembly 330 and the second side light source assembly 340 to complement each other when emitting light, ensuring that the light can fully cover every corner of the first light output surface 460, effectively reducing the light spots and dark areas caused by the limitation of the light source position, and improving the overall lighting uniformity.

[0063] Please refer to Figure 2 As shown, the lamp 100 further includes an inner frame 500. The inner frame 500 includes a top wall 510 and an inner side wall 520. The extending direction of the inner side wall 520 is the same as that of the outer side wall 210. Moreover, the inner side wall 520 and the outer side wall 210 are respectively located on both sides of the top wall 510, jointly enclosing a light source installation space 600, making the internal and external structures of the lamp 100 more coordinated and unified, not only improving the aesthetics of the lamp 100, but also enhancing its overall sense.

[0064] The main light source assembly 700 is disposed in the light source installation space 600 and includes a second light emitting member 710 that emits light in a direction away from the top wall 510. The light source installation space 600 not only provides a stable installation environment for the main light source assembly 700, but also can, to a certain extent, protect the main light source assembly 700 from the direct influence of the external environment, such as dust, water vapor, etc.

[0065] The light guide member 800 is disposed in the light emitting path of the main light source assembly 700 and has the same extending direction as the outer side wall 210. The light guide member 800 includes a second light emitting surface 820 opposite to the light emitting direction of the first light emitting surface 460 and a bottom light emitting surface 830. The light guide member 800 emits the light irradiated on the light guide member 800 by the main light source assembly 700 through the second light emitting surface 820 and the bottom light emitting surface 830. The light guide member also includes a second light emitting surface 820 facing away from the outer side wall 210. At least part of the light emitted by the second light emitting member 710 passes through the second light emitting surface 820 and the bottom light emitting surface 830 after passing through the second reflecting surface 810. When the light emitted by the second light emitting member 710 passes through the second reflecting surface 810, it will be reflected and redirected, and then emitted through the second light emitting surface 820 and the bottom light emitting surface 830. This process not only helps to improve the utilization efficiency of the light, but also can control the distribution range and direction of the light, achieving a more uniform lighting effect.

[0066] In summary, for the lamp 100 according to the embodiment of the present utility model, the side light source assembly 300 and the light distribution member 400 are arranged in the receiving groove 220 of the outer frame 200, making the appearance of the lamp 100 more concise and beautiful. Among them, the light distribution member 400 includes a first light-emitting surface 460 and a first reflecting surface 450. The projection range of the first reflecting surface 450 on the first light-emitting surface 460 of the side light source assembly 300 covers the light-emitting area of the side light source assembly 300, so that the light emitted by the side light source assembly 300 can be fully captured and guided by the first reflecting surface 450, reducing the direct loss or ineffective reflection of light, thereby enhancing the light efficiency of the lamp 100. At the same time, it helps the light to be emitted more evenly through the first light-emitting surface 460. Moreover, the first light-emitting member 320 in the first side light source assembly 330 extends to the end of the first side 230, and the short side of the second side light source assembly 340 is arranged close to the long side of the first side light source assembly 330, making the light efficiency at the corner of the lamp 100 consistent with that at other positions and improving the overall uniformity of illumination.

[0067] The above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model.
