Description

Technical Field

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

[0002] Most light guide designs on the market currently employ an internally hollowed-out cavity structure, utilizing the reflection of light within the cavity for light transmission. The disadvantage of this structure is that light undergoes not only reflection but also refraction within the cavity. The refracted light is scattered, resulting in scattered light rays emitted from the light-emitting surface of the light guide. Furthermore, since the light guide is an empty cavity, the light from the source is not absorbed by the material's properties, leading to a glaring and chaotic appearance to the observer. Utility Model Content

[0003] The main purpose of this invention is to provide a lighting component that aims to improve the softness of light.

[0004] To achieve the above objectives, the lighting component proposed in this utility model includes:

[0005] Light-emitting components; and

[0006] A light guide column, comprising a first light guide segment, a second light guide segment, and a third light guide segment connected in sequence. The first light guide segment is disposed opposite to the light-emitting element. The side of the first light guide segment facing the light-emitting element is the light-incident surface. The side of the third light guide segment away from the first light guide segment is the light-emitting surface. The first light guide segment, the second light guide segment, and the third light guide segment are all solid structures. The distance between the light-emitting element and the light-incident surface is s, where 0.2mm≤s≤0.8mm.

[0007] In one embodiment, the length of the first light guide segment is L1, the length of the second light guide segment is L2, and the length of the third light guide segment is L3, where L1 > L2 > L3.

[0008] In one embodiment, the light-emitting element is located on the axis of the light guide post.

[0009] In one embodiment, the roughness of the incident surface is a, where a < 3.2 μm.

[0010] In one embodiment, the light-emitting surface is a frosted surface.

[0011] In one embodiment, the light guide post is made of acrylic material.

[0012] In one embodiment, the first light guide segment, the second light guide segment, and the third light guide segment are all rectangular in shape.

[0013] In one embodiment, the corners of the second light guide segment and the third light guide segment are chamfered.

[0014] In one embodiment, the height of the first light guide segment is h1, the height of the second light guide segment is h2, and the height of the third light guide segment is h3, where 4.6mm≤h1≤5.5mm, 2mm≤h2≤2.9mm, and 2.8mm≤h3≤3.5mm.

[0015] In one embodiment, a mounting ear is connected to the first light guide segment, and the mounting ear is provided with a mounting hole. The light guide post is locked to an external device through the mounting hole and the engagement of a screw.

[0016] In this invention, the distance between the light-emitting element and the light-incident surface is set between 0.2mm and 0.8mm, thereby making the light emitted by the light-emitting element more evenly distributed within the light guide column, reducing the appearance of light spots and dark areas, and thus improving the lighting quality of the light source. Furthermore, the first, second, and third light guide sections are all made into solid structures, thereby reducing the refraction of light within the light guide column, and further reducing scattered light within the light guide column, so that the light emitted through the light guide column is not messy or dazzling. At the same time, the solid light guide column also absorbs some light, thus preventing the light emitted through the light guide column from being too strong and dazzling, thereby improving the softness of the light and improving the user experience.

[0027] Reference Figures 1 to 3 This utility model proposes a lighting component, comprising:

[0028] Light-emitting element 10; and

[0029] The light guide column includes a first light guide segment 21, a second light guide segment 22, and a third light guide segment 23 connected in sequence. The first light guide segment 21 is disposed opposite to the light-emitting element 10. The side of the first light guide segment 21 facing the light-emitting element 10 is the light-incident surface 211, and the side of the third light guide segment 23 facing away from the first light guide segment 21 is the light-emitting surface 231. The first light guide segment 21, the second light guide segment 22, and the third light guide segment 23 are all solid structures. The distance between the light-emitting element 10 and the light-incident surface 211 is s, where 0.2mm≤s≤0.8mm.

[0030] In this invention, the distance between the light-emitting element 10 and the light-incident surface 211 is set between 0.2mm and 0.8mm, thereby making the light emitted by the light-emitting element 10 more evenly distributed within the light guide column, reducing the appearance of light spots and dark areas, and thus improving the lighting quality of the lamp. Furthermore, the first light guide segment 21, the second light guide segment 22, and the third light guide segment 23 are all made of solid structures, thereby reducing the refraction of light within the light guide column, and further reducing scattered light within the light guide column, so that the light emitted through the light guide column is not chaotic or dazzling. At the same time, the solid light guide column also absorbs some light, thus preventing the light emitted through the light guide column from being too strong and dazzling, thereby improving the softness of the light and enhancing the user experience. The light-emitting element 10 can be a lamp bead, or an LED lamp, OLED, etc.

[0031] Specifically, the length of the first light guide segment 21 is L1, the length of the second light guide segment 22 is L2, and the length of the third light guide segment 23 is L3, where L1 > L2 > L3. When light is emitted from the light-emitting element 10, due to the divergence angle of the light source itself, the light may enter the first light guide segment 21 of the light guide post at different angles. The larger diameter of the first light guide segment 21 can more effectively capture these rays, reducing light loss at the incident end. At the same time, as the diameter of the light guide segment gradually decreases, the transmission path of the light inside the light guide post becomes more compact, which helps to reduce scattering and loss of light during transmission and improve the efficiency of light transmission.

[0032] Furthermore, the light-emitting element 10 is located on the axis of the light guide column. This centrally positions the light-emitting element 10, allowing light to propagate and distribute more effectively within the light guide column, resulting in a more uniform lighting effect. This avoids overly concentrated or unevenly dim light, providing users with a more comfortable and consistent lighting experience.

[0033] Specifically, the roughness of the light-incident surface 211 is 'a', where 'a' < 3.2 μm, meaning the light-incident surface 211 is a smooth surface. A smooth surface reduces scattering and reflection of light when it enters the first light guide segment 21, allowing more light to smoothly enter the light guide column, thereby improving light coupling efficiency. The smooth surface also helps maintain the directionality of the light, enabling it to propagate along a predetermined path after entering the light guide column, reducing light deviation and loss during transmission, and thus reducing scattered light within the light guide column. This further improves the coupling efficiency and directionality of the light.

[0034] Furthermore, the light-emitting surface 231 is a frosted surface. The frosted surface disrupts specular reflection of light, causing diffuse reflection at the light-emitting surface 231, thus achieving uniform light scattering and improving the uniformity and softness of the illumination. Simultaneously, by frosting the light-emitting surface 231, its brightness can be significantly reduced, minimizing glare and making the light more comfortable and less dazzling, thereby improving the user experience. Finally, because the frosted surface produces diffuse reflection, light can be scattered in more directions, increasing the light coverage and improving the lighting effect.

[0035] In one embodiment, the light guide column is made of acrylic. Acrylic has extremely high transparency, with a light transmittance of over 92%, even approaching 100%. This ensures efficient and stable light transmission within the light guide column, reducing light loss. Acrylic's specific gravity is only half that of glass, allowing the light guide column to maintain high performance while significantly reducing weight, facilitating transportation and installation. Acrylic has good bending resistance and impact resistance, and is not easily broken even under external impact, making it suitable for applications requiring frequent movement or subject to impact. Acrylic resists ultraviolet radiation and is not prone to yellowing or brittleness from prolonged exposure to sunlight. It also resists chemical corrosion, is not easily corroded or discolored, and is suitable for outdoor or harsh environments, thus extending the lifespan of the light guide column. Compared to other materials such as glass, acrylic is less expensive yet performs no worse, giving acrylic light guide columns a significant cost-performance advantage and reducing manufacturing costs. Of course, in other embodiments, the light guide post can also be made of polycarbonate (PC), acrylic resin, glass, epoxy resin, etc.

[0036] In one embodiment, the first light guide segment 21, the second light guide segment 22, and the third light guide segment 23 are all rectangular. The rectangular arrangement of the first light guide segment 21, the second light guide segment 22, and the third light guide segment 23 effectively transmits light and reduces light loss. Simultaneously, the rectangular arrangement allows light to be refracted and reflected inside the light guide column, thereby uniformly distributing the light to the desired area and improving the light transmission efficiency of the light guide column.

[0037] In one embodiment, the corners of the second light guide segment 22 and the third light guide segment 23 are chamfered. The chamfering guides and alters the direction of light emitted from the light source, making light transmission within the light guide column smoother; it also optimizes the light transmission path, reducing scattering and loss at the corners. The chamfering reduces reflection and refraction of light at the corners of the light guide column, thereby reducing light loss. Furthermore, when subjected to external forces or vibrations, the chamfering reduces stress concentration at the corners, thus lowering the risk of light guide column breakage and extending its lifespan. The chamfering also improves the aesthetics of the light guide column, making its corners more rounded and smooth, thus enhancing the overall visual effect.

[0038] Specifically, the height of the first light guide segment 21 is h1, the height of the second light guide segment 22 is h2, and the height of the third light guide segment 23 is h3, where 4.6mm ≤ h1 ≤ 5.5mm, 2mm ≤ h2 ≤ 2.9mm, and 2.8mm ≤ h3 ≤ 3.5mm. The heights of the first light guide segment 21, the second light guide segment 22, and the third light guide segment 23 are represented as their lengths along the axis of the light guide column. By rationally setting the heights of the first light guide segment 21, the second light guide segment 22, and the third light guide segment 23, the transmission path of light within the light guide column is optimized, light loss during transmission is reduced, and the overall light transmission efficiency is improved.

[0039] In one embodiment, a mounting ear 24 is connected to the first light guide segment 21, and the mounting ear 24 is provided with a mounting hole 241. The light guide post is locked to an external device through the mounting hole 241 and a screw. By providing the mounting ear 24 and the mounting hole 241, the installation and removal of the light guide post are facilitated. The locking method of the mounting hole 241 and the screw is simple, reliable, and low-cost, thereby reducing the manufacturing cost of the light guide post.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
