Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lamp. Background Technology

[0002] LED lighting is increasingly widely used, including in conventional lighting, smart home appliance indicator lights, and ambient lighting. These lights typically employ light guides to direct the light towards the desired illumination direction. As technology advances and people increasingly value the immersive lighting experience, their demands for the lighting effects of different fixtures are also rising.

[0003] LED lighting fixtures typically consist of a light panel and light guides mounted on it. In existing LED lighting solutions, most light sources (LED chips) are arranged in a linear array on the light panel, with a conventional light guide at the top. Due to the relatively large spacing between the light sources on the light panel, the conventional light guide design fails to effectively optimize the light transmission path, resulting in poor color mixing, especially noticeable color separation at the bottom of the light guide, thus affecting the overall light output of the lighting fixture.

[0004] Traditional lighting technology often improves the overall light mixing effect of a luminaire by increasing the number of light sources on the lamp panel. However, in some luminaires with light sources arranged in a straight line, adding light sources only in the direction of the light source arrangement or perpendicular to the light source arrangement can easily lead to uneven light intensity distribution on the surface of the light guide column, especially forming elliptical dark areas perpendicular to the light source arrangement direction. Furthermore, increasing the number of light sources also brings problems such as increased energy consumption and reduced space utilization of the lamp panel. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems and provide a lamp.

[0006] The present invention adopts the following technical solution:

[0007] A lighting fixture includes a light guide column and a lamp panel. The light guide column and the lamp panel are arranged opposite to each other. The light guide column has a frustum portion near the lamp panel. The lamp panel is provided with a light source component. The side of the frustum portion facing the lamp panel is provided with a first diffuser groove opposite to the light source component. The outer surface of the frustum portion is curved. Part of the light emitted by the light source component is refracted twice by the inner surface of the first diffuser groove and the outer surface of the frustum portion, and then evenly scattered around the frustum portion. The inner surface of the first diffuser groove and the outer surface of the frustum portion are arranged symmetrically about the central axis of the light guide column.

[0008] In one embodiment, the curvature of the outer surface of the frustum matches the angle of the light emitted from the inner surface of the first diffuser groove, thereby uniformly guiding the light around the outer surface of the frustum through refraction.

[0009] In one embodiment, the first astigmatism groove is a semi-ellipsoidal structure or a hemispherical structure.

[0010] In one embodiment, the lamp panel is provided with multiple light source components, and the light guide column is also provided with multiple second diffuser slots, with the multiple light source components corresponding one-to-one with the first diffuser slot and the multiple second diffuser slots.

[0011] In one embodiment, the light guide post includes at least one pair of second diffuser grooves, each pair of second diffuser grooves being disposed on both sides of the first diffuser groove and being symmetrical about the first diffuser groove, the second diffuser groove being a hemispherical structure, a semi-ellipsoidal structure, or a multi-groove lateral connection structure.

[0012] In one embodiment, the plurality of light source components include a first light source component and at least one pair of second light source components. The first light source component is directly opposite to the first diffuser slot, and each second light source component is directly opposite to a corresponding second diffuser slot. Both the first light source component and the second light source component are used to emit light of any color.

[0013] In one embodiment, the lamp panel is provided with a plurality of light source components, and the opening of the first diffuser groove covers the plurality of light source components.

[0014] In one embodiment, the plurality of light source components include a first light source component and a plurality of second light source components. Both the first light source component and the second light source components are used to emit light of any color. The plurality of second light source components form a ring structure, and the first light source component is disposed within the ring structure.

[0015] In one embodiment, the plurality of light source components each constitute an LED bead, or the plurality of light source components are integrated into the same LED bead.

[0016] In one embodiment, the light guide column further includes an end portion, which is disposed at both ends of the frustum portion and the lamp plate, and is connected to the frustum portion. The end portion has a conical structure, a frustum structure, or a cylindrical structure, and is integrally formed with the frustum portion.

[0017] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0018] This utility model provides a lighting fixture. First, a first diffuser groove is set in the frustum-shaped portion near the lamp panel. A light source component is set on the lamp panel opposite to the first diffuser groove. Part of the light emitted by the light source component passes through the first diffuser groove, which effectively deflects and diffuses the light before it enters the frustum-shaped portion of the light guide column. This results in a uniform light distribution within the frustum-shaped portion. The light then undergoes further transmission and reflection on the outer surface of the frustum-shaped portion, making the light output from the frustum-shaped portion more uniform. This reduces the bright spots caused by direct light emission from the light source component entering the frustum-shaped portion, thus providing an anti-glare function and improving the user experience. The first diffuser groove effectively deflects and diffuses the light, and also optimizes the light intensity distribution on the surface of the frustum-shaped portion, eliminating dark areas.

[0019] Secondly, the setting of the first diffuser slot can eliminate the dark areas of the light emitted by the lamp. Therefore, the setting of the light source components on the lamp board can shorten the distance between the white light beads and the RGB light beads, so as to reduce the loss of light during the mixing process due to the large distance, avoid poor light mixing effect and color separation phenomenon, significantly improve the uniformity of light distribution, make the light emission effect of the lamp better, and meet the user's demand for a high-end experience.

[0020] Furthermore, by setting the first diffuser slot, uniform color mixing and uniform light distribution can be achieved with a small number of LEDs, thus reducing the number of LEDs, design complexity and cost, and energy consumption.

[0021] Furthermore, the inner surface of the first diffuser groove and the outer surface of the frustum are both rotationally symmetrical about the same axis. The light source component is positioned opposite the first diffuser groove, meaning the LEDs of the light source component are symmetrically distributed and can be arranged close together, effectively reducing light loss in the mixing path and suppressing color separation at the bottom of the frustum. Moreover, the outer surface of the frustum is curved, and its curvature matches the angle of light emitted from the inner surface of the first diffuser groove, allowing for different light mixing effects to be achieved according to various needs.

[0036] like Figures 1 to 10 As shown, the present invention provides a lamp 1, which includes a light guide column 10 and a lamp plate 12, wherein the light guide column 10 and the lamp plate 12 are arranged opposite to each other.

[0037] The light guide post 10 has a frustum-shaped portion 101 near the lamp plate 10, and its outer surface is curved. A light source component 120 is provided on the lamp plate 12. A first diffuser groove 1021, opposite to the light source component 120, is provided on the side of the frustum-shaped portion 101 facing the lamp plate 12. Part of the light emitted from the light source component 120 is refracted twice by the inner surface of the first diffuser groove 1021 and the outer surface of the frustum-shaped portion 101, and then evenly scattered around the frustum-shaped portion 101. The inner surface of the first diffuser groove 1021 and the outer surface of the frustum-shaped portion 101 are rotationally symmetrical about the central axis of the light guide post 10. The light guide post 10 is made of a transparent light-guiding material and has a light-guiding function. The curvature of the outer surface of the frustum-shaped portion 101 matches the angle of the light emitted from the inner surface of the first diffuser groove 1021, and the light is evenly guided around the outer surface of the frustum-shaped portion 101 through refraction.

[0038] Specifically, in combination Figure 1 and Figure 2 As shown, the frustum-shaped portion 101 of the light guide post 10 includes an annular abutment portion 1011 near the lamp panel 10 and a light guide surface 1012 facing the lamp panel 12. The light guide surface 1012 is surrounded by the abutment portion 1011, and the light guide surface 1012 is lower than the top surface of the abutment portion 1011, so that the side of the frustum-shaped portion 101 facing the lamp panel 10 forms a receiving space. This receiving space is used to accommodate the light source component 120 and other components on the lamp panel 12. After the light guide post 10 and the lamp panel 12 are installed, the light guide surface 1012 of the frustum-shaped portion 101 is at a certain distance from the light source component 120. The first diffuser groove 1021 is recessed inward on the surface of the light guide surface 1012, forming an inward concave structure with an opening on the surface of the light guide surface 1012. This inward concave structure can be a semi-ellipsoidal structure, a hemispherical structure, or other curved surface structure that is rotationally symmetrical about a central axis.

[0039] In one embodiment, the light guide post 10 is provided with a single first diffuser groove 1021, for reference. Figure 4 A light source component 120 is disposed in the middle of the lamp panel 12, and a first diffuser groove 1021 is formed opposite to the light source component 120 on the frustum portion 101. The inner surface of the first diffuser groove 1021 and the outer surface of the frustum portion 101 are rotationally symmetrical about the central axis of the light guide post 10. In this embodiment, the area of ​​the opening of the first diffuser groove 1021 is smaller than the area of ​​the light guide surface 1012, and it covers the light source component 120. The number of light source components 120 can be one, which is a white LED. The inner surface of the first diffuser groove 1021 can be frosted.

[0040] The internal cross-section of the first astigmatism groove 1021 can be set as a free curve, as shown in the reference. Figure 1 The arrows illustrate the refraction and reflection paths of the light emitted from the light source component 120. Similarly, the light emitted from the light source component 120 first enters the first diffuser groove 1021 inside the frustum portion 101. Since the cross-section of the first diffuser groove 1021 is a free curve with a curvature less than 0, and it is at a certain height from the white LED, and the interior of the first diffuser groove 1021 has a frosted surface treatment, most of the light is deflected and directly transmitted out of the frustum portion 101 after passing through it. A small portion of the light is incident on the surface of the frustum portion 101 with a special curvature and then reflected. Therefore, by adjusting the curvature of the inner surface of the first diffuser groove 1021 and the outer surface of the frustum portion 101, the light distribution on the surface of the frustum portion 101 can be made uniform.

[0041] The number of light source components 120 can also be three, including a first light source component 1201 and a pair of second light source components 1202, that is, composed of three high-brightness LED beads. The first light source component 1201, which is an RGB LED bead, is located at the axial center of the frustum portion 101, and the second light source components 1202 are respectively arranged on both sides of the first light source component 1201. The first light source component 1201 is an RGB LED bead, and the second light source components 1202 are white LED beads. The RGB LED bead and the two white LED beads are arranged in a symmetrical distribution. The three LED beads face the first diffuser groove 1021, and the opening of the first diffuser groove 1021 covers the three LED beads. The light emitted by the three LED beads simultaneously enters the frustum portion 101 from the inner surface of the first diffuser groove 1021.

[0042] Because there is a certain distance between the light source component 120 and the light guide surface 1012 of the frustum portion 101, after the light source component 120 emits light, it first passes through the receiving space of the frustum portion 101, and then enters the light guide surface 1012 and the first diffuser groove 1021 provided on the light guide surface 1012. The light source component 120 faces the first diffuser groove 1021, so that most of the light emitted by it enters the frustum portion 101 through the interior of the first diffuser groove 1021. Since the interior of the first diffuser groove 1021 is a free-form surface, the first diffuser groove 1021 can effectively deflect and diffuse the light, thereby achieving a uniform distribution of light on the outer surface of the frustum portion 101 and eliminating the dark areas emitted by the lamp 1. Because the first diffuser slot 1021 can eliminate the dark area of ​​the light emitted by the lamp 1, the light source component 120 on the lamp board 12 can be set so that the white light bead can be closer to the RGB light bead to reduce the loss of light in the mixing process, avoid poor light mixing effect and color separation phenomenon caused by excessive spacing between the light beads, and make the light output effect of the lamp 1 better, so as to meet the user's high experience needs.

[0043] In the embodiment where only a single first diffuser slot 1021 is provided in the frustum portion 101, the lamp board 12 may also be provided with multiple light source components 120, including a first light source component 1201 and multiple second light source components 1202. The first light source component 1201 can be an RGB LED, used to emit light of any color; the multiple second light source components 1202 can be white LEDs, used to emit white light, or can emit light of any color. (Reference) Figure 10 The first light source component 1201 is disposed in the middle of the lamp plate 12, and the plurality of second light source components 1202 are evenly distributed around the first light source component 1201 on the lamp plate 12 to form a ring structure. In this embodiment, the first light source component 1201 faces the diffuser groove 102, and the plurality of ring-arranged second light source components 1202 face the light guide surface 1012 of the frustum portion 101.

[0044] Using a ring-shaped light source array, the light-emitting points of lamp 1 are arranged in a ring. The white light emitted by the second light source component 1202 directly enters the frustum portion 101, integrating the white light into the ring area and optimizing the uniformity of the light source distribution. Additionally, the light from the RGB LEDs enters the frustum portion 101 from the area of ​​the diffuser slot 102, fundamentally reducing color separation. In this embodiment, a frustum portion 101 with a single diffuser slot 102 is used. The cross-section of the frustum portion 101 satisfies a quadratic surface with a curvature greater than 0. The opening area of ​​the diffuser slot 102 is larger than the light-emitting area of ​​the RGB LEDs but smaller than the ring-shaped light-emitting area, causing some light to be deflected at a large angle, thus ensuring uniform light distribution on the surface of the frustum portion 101.

[0045] In one embodiment, the first diffuser groove 1021 can also be configured to be recessed inward along the entire light guide surface 1012 of the frustum portion 101, forming a large, fully recessed first diffuser groove 1021, that is, the opening of the first diffuser groove 1021 coincides with the light guide surface 1012 of the frustum portion 101, such as... Figure 5 As shown, the first diffuser groove 1021 can be a semi-ellipsoidal structure or a hemispherical structure. In this embodiment, the first diffuser groove 1021 faces all light source components 120. The first diffuser groove 1021 can effectively deflect and diffuse light, thereby achieving uniform light distribution on the outer surface of the frustum portion 101 and eliminating dark areas in the light emitted by the lamp 1.

[0046] Furthermore, since the outer surface of the frustum 101 is a curved structure, and the inner surface of the first diffuser groove 1021 is symmetrical about the outer surface of the frustum 101 around the central axis of the light guide column, the light emitted by the light source component 120 is first deflected by the diffuser groove 102 of the frustum 101, so that the light is evenly distributed inside the frustum 101. This can reduce the light effect of the light source component 120 directly emitting light and having its own bright spots, so that the light output effect of the lamp 1 has an anti-glare function. The light is further transmitted and reflected by the outer surface of the frustum 101, making the light output of the lamp 1 more uniform and improving the user experience.

[0047] In another embodiment, the lamp panel 12 is provided with a plurality of light source components 120, and the light guide column 10 is provided with a plurality of second diffuser slots 1022. The plurality of light source components 120 are arranged in a one-to-one correspondence with the first diffuser slot 1021 and the plurality of second diffuser slots 1022. (See reference) Figure 1 The plurality of light source components 120 includes a first light source component 1201 and at least one pair of second light source components 1202. The first light source component 1201 is positioned at the center of the lamp panel 12, and the second light source components 1202 are symmetrically distributed on both sides of the first light source component 1201. Correspondingly, the light guide post 10 forms a plurality of diffuser grooves at positions opposite to the plurality of light source components 120. The light guide post 10 includes at least one pair of second diffuser grooves 1022, which are respectively disposed on both sides of the first diffuser groove 1021 and symmetrically arranged with the first diffuser groove 1021 as the center. The first diffuser groove 1021 is a hemispherical or semi-ellipsoidal structure, and the second diffuser groove 1022 is a hemispherical, semi-ellipsoidal, or multi-groove laterally connected structure (similar to a Fresnel lens structure).

[0048] The first light source component 1201 faces the first diffuser groove 1021, and the light emitted by it enters the light guide column 10 from the inner surface of the first diffuser groove 1021. Each second light source component 1202 faces the corresponding second diffuser groove 1022, and the light emitted by it enters the light guide column 10 from the inner surface of the second diffuser groove 1022. The first light source component 1201 can be configured as an LED light source emitting light of any color, and the second light source component 1202 can be configured as an LED light source emitting white light or emitting light of any color.

[0049] When the second diffuser 1022 is configured as a hemispherical or semi-ellipsoidal structure, the light from the light source component 120 can be effectively deflected and diffused accordingly, thereby achieving a more uniform light distribution on the surface of the frustum 101 and eliminating dark areas. Furthermore, combined with the special curved structure of the outer surface design of the frustum 101, the light undergoes further transmission and reflection through the outer surface, reducing or even eliminating bright spots in the lamp and providing anti-glare functionality.

[0050] A preferred embodiment, refer to Figure 6 and Figure 7 In a cross-section perpendicular to the arrangement direction of the plurality of light source components 120, the internal cross-section of the second diffuser groove 1022 can be set as a quadratic curve cross-section, for example, the second diffuser groove 1022 is a semi-ellipsoidal structure, and the opening area of ​​the second diffuser groove 1022 is set to be smaller than the light-emitting area of ​​the second light source component 1202. In this embodiment, some of the light from the second light source component 1202 does not pass through the second diffuser groove 1022 for deflection, but propagates along the original light path and illuminates the lower middle part of the frustum portion 101; the stronger light from the central part of the second light source component 1202 is deflected at a large angle by the second diffuser groove 1022 to the top region of the frustum portion 101. Therefore, by controlling the ratio of the opening area of ​​the second diffuser groove 1022 to the light-emitting area of ​​the second light source component 1202, the proportion of light deflection on the light-emitting surface of the second light source component 1202 is controlled to satisfy the uniform light distribution of the second diffuser groove 1022 in this cross-sectional direction. This design allows the present invention to eliminate the color separation problem of the frustum 101 by using a small number of LED beads, while optimizing the space utilization efficiency of the lamp panel 12 and improving the overall lighting performance of the lamp 1.

[0051] In general, the first diffuser groove 1021 is configured to form a semi-ellipsoidal structure, a hemispherical structure, or other curved surface structure that is rotationally symmetrical about a central axis, while the structure of the second diffuser groove 1022 can be determined according to specific lighting effect requirements. In one embodiment, refer to... Figure 8 and Figure 9 When the second diffuser groove 1022 is configured as a multi-groove lateral connection structure, the second light source component 1202 overlaps with the opening of the corresponding second diffuser groove 1022, and the edge of the second light source component 1202 in the length and / or width direction protrudes relative to the area where the opening is located.

[0052] The second diffuser groove 1022 is designed as a diffuser groove with a multi-groove laterally connected structure, so that the refractive surface of the frustum 101 is segmented, and each surface has a different curvature, with the curvature being greater closer to the center of the frustum 101. For example... Figure 8 The light path shown in the diagram distributes the light evenly across the entire outer surface of the frustum 101 after passing through each refracting surface.

[0053] The plurality of light source components 120 can each constitute an LED chip, or the plurality of light source components 120 can be integrated into the same LED chip. The plurality of light source components 120 are respectively configured in a one-to-one correspondence with the first diffuser slot 1021 and the second diffuser slot 1022.

[0054] In the embodiment that integrates RGB LEDs and two white LEDs into a single LED, the white LEDs are distributed on both sides of the RGB LED area, which effectively solves the color separation problem and achieves higher light mixing uniformity. This design reduces the number of LEDs, making the structure and manufacturing of the lamp 1 more convenient.

[0055] The light guide column 10 also includes an end portion 103 connected to the frustum portion 101. The end portion 103 and the lamp panel 12 are respectively disposed at both ends of the frustum portion 101. The frustum portion 101 and the end portion 103 cooperate with each other to uniformly conduct the light emitted by the light source component 120 to the frustum portion 101 and the end portion 103, so that the light guide column 10 has no dark areas or bright spots, thereby making the lamp 1 of this utility model emit light uniformly.

[0056] The end portion 103 can be configured as a conical structure, a frustum structure, or a cylindrical structure, depending on the specific light output effect of the lamp 1 and the structural requirements of the application scenario. The end portion 103 is integrally formed with the frustum portion 101, which is simple to manufacture and easy to install.

[0057] The lamp 1 also includes a housing (not shown), which is made of transparent PC or acrylic material and is used to cover the light guide post 10 and the lamp plate 12.

[0058] The number of diffuser slots, the size of the openings, the arrangement of the light source components 120, and the selection of the light source emission color provided in this application can be designed according to various light emission and mixing effect requirements. The above-listed embodiments are only some of the implementation methods. Without departing from the core idea of ​​this utility model, more variations and embodiments can be made, which will not be listed here.

[0059] In summary, the present invention provides a lighting fixture in which at least one first diffuser groove 1021 is provided on the frustum portion 101 of the light guide column 10 of the lighting fixture 1. The first diffuser groove 1021 is directly opposite to the light source component 120 on the lamp panel 12, so that some light is deflected and directly transmitted out of the frustum portion 101, and a small portion of light is incident on the surface of the frustum portion 101 with a special curvature and then reflected. Therefore, by adjusting the curvature of the inner surface of the first diffuser groove 1021 and the outer surface of the frustum portion 101, the light distribution on the surface of the frustum portion 101 can be made uniform. This solves the problems of uneven light distribution on the light guide column of the existing lighting fixture, which prevents rendering on a large surface area of ​​the light guide column, and the color separation problem that exists after the light passes through the frustum portion 101.
