Description

Technical Field

[0001] This application relates to the field of lighting fixtures, specifically to an optical component for a linear light and a linear light itself. Background Technology

[0002] Linear lights are a type of lighting fixture whose light sources are arranged in a straight line. They are characterized by low power consumption, long lifespan, and high brightness, and are widely used in outdoor landscape lighting, municipal engineering, lighting projects, and indoor lighting.

[0003] Currently, most linear lights consist of an LED assembly, a reflector, and an anti-glare shield. The LED assembly serves as the main light source, the reflector enhances the intensity of the light source provided by the LED assembly, and the anti-glare shield achieves an anti-glare effect to improve the user experience.

[0004] To ensure that the anti-glare shield is effective while avoiding blocking the light from the LED components, most anti-glare shields in this technology have a grid-like structure. However, grid-like anti-glare shields are prone to accumulating dust and are difficult to clean, which, over time, significantly affects the overall aesthetics of the linear lights.

[0005] Therefore, there is an urgent need to provide a new type of optical component for linear lights and a linear light in order to solve the above problems. Utility Model Content

[0006] The purpose of this application is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this application is to provide an optical component for a linear light and a linear light itself.

[0007] To achieve the above objectives, this application adopts the following technical solution: Firstly, this application provides an optical component for a linear light, including a reflector and an anti-glare shield mounted on the reflector. Both the reflector and the anti-glare shield are elongated structures. The reflector has multiple reflective cavities spaced apart along its length. The anti-glare shield includes:

[0008] The light-transmitting part is made of a light-transmitting material. The projection of the light-transmitting part on the reflector cup covers all the reflector cavities. The surface of the light-transmitting part facing away from the reflector cup is a smooth surface, such as a plane, a curved surface or a concave surface, as long as the surface is smooth and does not easily accumulate dust.

[0009] The anti-glare portion is arranged around the light-transmitting portion and extends in a direction away from the reflector.

[0010] As an alternative to the optical component for the linear light, the anti-glare portion has at least one V-shaped structure in its longitudinal section.

[0011] As an alternative to the optical component for the linear light, at least one inner surface of the V-shaped structure has a textured surface.

[0012] As an optional optical component for the linear light, the surface of the light-transmitting portion facing the reflector has a light-mixing surface. Multiple light-mixing surfaces are spaced apart along the length of the light-transmitting portion, and each light-mixing surface corresponds one-to-one with a reflector cavity. The light-mixing surface can be a microstructured convex surface or a flat surface.

[0013] As an optional optical component for the linear light, the surface of the light-transmitting part facing the reflector has a supporting boss, the supporting boss is arranged around the periphery of the light-mixing surface, and the supporting boss abuts against the reflector.

[0014] As an optional optical component for the linear light, one of the anti-glare shield and the reflector has a first latching protrusion, and the other has a first latching groove that engages with the first latching protrusion.

[0015] As an optional optical component for the linear light, the reflector cup also has a first limiting protrusion and a second limiting protrusion disposed parallel to and spaced apart from the first limiting protrusion. The first limiting protrusion and the second limiting protrusion are respectively located on both sides of the reflective cavity, and at least a portion of the anti-glare shield is located between the first limiting protrusion and the second limiting protrusion.

[0016] As an optional solution for the optical component of the linear light, the optical component of the linear light also includes a reflector cup bracket, which is connected to the side of the reflector away from the anti-glare shield.

[0017] As an optional optical component for the linear light, one of the reflector and the reflector bracket has a second latching protrusion, and the other has a second latching groove that engages with the second latching protrusion.

[0018] Secondly, this application provides a linear light, including a housing, an LED assembly mounted on the housing, and an optical component for the linear light as described above. The LED assembly has a long strip structure and has a plurality of LEDs spaced apart along its length. The LEDs are arranged in a one-to-one correspondence with the reflective cavity.

[0019] As an alternative to the linear light, the housing has a mounting cavity, and the anti-glare portion of the anti-glare cover is embedded in the mounting cavity, or the anti-glare portion of the anti-glare cover is externally placed in the mounting cavity.

[0020] The beneficial effects of this application are as follows:

[0021] The optical components for linear lights provided in this application include a reflector and an anti-glare cover mounted on the reflector. Both the reflector and the anti-glare cover are elongated structures. The reflector has multiple reflective cavities spaced apart along its length. The anti-glare cover includes a light-transmitting part and an anti-glare part surrounding the light-transmitting part and extending away from the reflector. The light-transmitting part is made of a light-transmitting material, and the projection of the light-transmitting part on the reflector covers all the reflective cavities, so that the light reflected from the reflective cavities must pass through the light-transmitting part before being emitted. That is, the light-transmitting part can be equivalent to the lens structure in a regular linear light. In addition, the surface of the light-transmitting part away from the reflector is a smooth surface, such as a flat surface, a curved surface, or a concave surface, as long as the surface is smooth and does not easily accumulate dust. This makes it easy to clean the surface of the light-transmitting part away from the reflector (i.e., the outer surface of the light-transmitting part) which does not easily accumulate dust.

[0022] The linear light provided in this application has the following advantages: 1) The surface of the anti-glare cover is not easy to accumulate dust, making it easy to clean; 2) The anti-glare cover integrates anti-glare function and lens function, eliminating the need for an additional lens, reducing assembly steps and improving assembly efficiency; 3) The anti-glare cover is compatible with both recessed and external installation, allowing for selective internal or external installation. When the anti-glare part of the anti-glare cover is installed externally, it can serve as a decorative component of the entire light, enhancing its aesthetics; 4) The anti-glare cover and reflector are easy to position and assemble without the need for positioning fixtures, reducing assembly difficulty.

[0037] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0038] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0039] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0040] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0041] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0042] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0043] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0044] refer to Figures 1 to 7As shown, the linear light provided in this application includes a housing 5 and an LED assembly 4 and an optical assembly both mounted on the housing 5. The housing 5 has a mounting cavity, in which at least a portion of the LED assembly 4 and the optical assembly are mounted. The housing 5 is used not only to mount the optical assembly but also to mount the entire linear light onto the work surface to be installed. The LED assembly 4 serves as the main light source, and the optical assembly is used to enhance or diffuse the light generated by the LED assembly 4. This not only provides sufficient light but also makes the light more uniform, achieving effects such as flexible lighting, beautifying the space, and guiding the path. It also has an anti-glare effect, which can improve the user experience.

[0045] Figure 1 This is an exploded view of the optical components for linear lights provided in the embodiments of this application. Figure 2 This is a cross-sectional schematic diagram of the optical component for a linear light provided in an embodiment of this application. For example... Figures 1 to 2 As shown, the optical components for linear lights provided in this application include an anti-glare cover 1, a reflector 2, and a reflector bracket 3. The reflector bracket 3 is used to mount the reflector 2, and the reflector 2 is used to enhance the intensity of the light source provided by the LED assembly 4. The anti-glare cover 1 is mounted on the reflector 2 and is used to achieve an anti-glare effect to improve the user experience.

[0046] In this example, the anti-glare shield 1, reflector 2, and reflector bracket 3 are all elongated structures. The LED assembly 4 and reflector bracket 3 are all mounted on the housing 5. The LED assembly 4 has multiple LEDs 41 spaced apart along its length, and the reflector 2 has multiple reflective cavities 21 spaced apart along its length. The reflective cavities 21 correspond one-to-one with the LEDs 41 and are used to enhance the intensity of the light emitted by the LEDs 41. It is understood that the LEDs 41 can be any light source product such as LEDs, and there are no restrictions here.

[0047] In one example, the reflector cup 2 can be made of PC material, and a layer of reflective material can be coated on the inner surface of the reflective cavity 21. This configuration can reduce the material cost of the reflector cup 2 and facilitate a lightweight design. Of course, in other examples, the reflector cup 2 can also be made of a material with good reflective properties, in which case there is no need to coat the inner wall of the reflective cavity 21 with additional reflective material.

[0048] To ensure that the anti-glare cover 1 effectively prevents glare while avoiding blocking the light from the LED assembly 4, most anti-glare covers 1 in related technologies have a grid-like structure. However, grid-like anti-glare covers 1 are prone to accumulating dust and are difficult to clean, which, over time, significantly affects the overall aesthetics of the linear light.

[0049] The anti-glare shield 1 provided in this application, through improvements to its structure, is not only less prone to dust accumulation and easier to clean, but also easier to process and assemble, resulting in lower costs.

[0050] Continue as Figures 1 to 2 As shown, the anti-glare cover 1 includes a light-transmitting part 11 and an anti-glare part 12 surrounding the light-transmitting part 11 and extending in a direction away from the reflector cup 2. The light-transmitting part 11 is made of a light-transmitting material, and the projection of the light-transmitting part 11 on the reflector cup 2 covers all the reflector cavities 21, so that the light reflected by the reflector cavities 21 must pass through the light-transmitting part 11 to be emitted. That is, the light-transmitting part 11 can be equivalent to the lens structure in a regular linear light. In addition, the surface of the light-transmitting part 11 away from the reflector cup 2 is flat, so that the surface of the light-transmitting part 11 away from the reflector cup 2 (i.e. the outer surface of the light-transmitting part 11) is not easy to accumulate dust and is easy to clean.

[0051] In short, the anti-glare cover 1 provided in this application integrates lens function and anti-glare function by setting a light-transmitting part 11 and an anti-glare part 12 surrounding the light-transmitting part 11. This allows linear lights using the anti-glare cover 1 to not only eliminate the need for additional lens structures, but also reduce assembly steps and improve assembly efficiency. Furthermore, designing the surface of the light-transmitting part 11 away from the reflector cup 2 (i.e., the outer surface of the light-transmitting part 11) as a flat surface can achieve the effect of not easily accumulating dust and being easy to clean. Compared with the anti-glare cover 1 in related technologies, this represents a significant improvement.

[0052] In one example, the outer surface of the light-transmitting part 11 is a smooth plane, which is not easy to get dusty and facilitates the maintenance and cleaning of the lamp's outer parts.

[0053] In one example, the light-transmitting part 11 and the anti-glare part 12 are made of the same material, both being made of a light-transmitting material, such as optical PC material. In another example, the light-transmitting part 11 and the anti-glare part 12 are made of different materials; the light-transmitting part 11 is made of a light-transmitting material, while the anti-glare part 12 can be made of a common material. Based on the core inventive points of the anti-glare shield 1 provided in this application, those skilled in the art can design and adjust the structure and material of the anti-glare shield 1 according to specific needs, provided that the light reflected by the reflective cavity 21 can be emitted through the light-transmitting part 11. No limitations are imposed here.

[0054] See also Figure 2 As shown, the longitudinal section of the anti-glare part 12 has a V-shaped structure, which reduces the amount of light emitted from the anti-glare part 12, thereby achieving the anti-glare effect. In other examples, the longitudinal section of the anti-glare part 12 may also have two or more arbitrary numbers of V-shaped structures, such as two, three, four, five, etc., which will not be listed here.

[0055] At least one inner surface of the V-shaped structure has a textured surface 12a, which diffuses and softens light to improve the anti-glare effect. This textured surface 12a can also conceal internal components of the linear light, enhancing the overall aesthetics of the lamp. Figure 3 This is a structural schematic diagram of the anti-glare shield 1 provided in this application. Figure 3 Combination Figure 2 As shown, there is one V-shaped structure, and only the inner surface of the V-shaped structure near the light-transmitting part 11 has a textured surface 12a, while the other inner surfaces are smooth planes. This configuration simplifies the molding process of the anti-glare part 12 and reduces molding costs.

[0056] In addition, the V-shaped structure of the anti-glare part 12 has a wavy concave-convex surface 12b on its end face. This wavy concave-convex surface 12b can weaken the ejector pin marks generated by the ejector pins on the end face of the anti-glare part 12 when the anti-glare cover 1 is demolded, thereby improving the overall aesthetics of the anti-glare cover 1.

[0057] It should be noted that, Figure 3 The outer contour of the overall structure of the anti-glare shield 1 shown is roughly a cuboid, and the overall shape of the anti-glare part 12 is roughly a ring-shaped rectangle. It is understood that those skilled in the art can adjust the structural shape of the anti-glare shield 1 at will according to specific needs. As long as it has the structural feature of "the anti-glare part 12 surrounding the light-transmitting part 11", it falls within the protection scope of this application. Here, the structural shape of the anti-glare shield 1 will not be described one by one.

[0058] Continue as Figures 2 to 3 As shown, the surface of the light-transmitting portion 11 facing the reflector cup 2 has a light-mixing surface 111. Multiple light-mixing surfaces 111 are spaced apart along the length of the light-transmitting portion 11, and each light-mixing surface 111 corresponds to a reflector cavity 21. This light-mixing surface 111 has a pearlescent effect; when light shines on the light-mixing surface 111, multiple reflections and refractions occur, producing light interference and enhancing the aesthetic appeal of the lighting. The light-mixing surface can be a microstructured convex surface or a flat surface, as long as it can function as a light-mixing surface. It is understood that the microstructured convex surface can be a pearlescent convex surface or other textured convex surfaces, which will not be listed here.

[0059] Figure 4 This is a schematic diagram of the reflector cup 2 provided in an embodiment of this application. For example... Figure 4 Combination Figures 2 to 3 As shown, the reflector cup 2 has a support platform 22, and reflective cavities 21 are spaced apart on the support platform 22. The support platform 22 has a first limiting protrusion 221 and a second limiting protrusion 222 spaced parallel to the first limiting protrusion 221. The first limiting protrusion 221 and the second limiting protrusion 222 are located on opposite sides of the reflective cavity 21, and at least a portion of the anti-glare shield 1 is located between the first limiting protrusion 221 and the second limiting protrusion 222. This arrangement facilitates the positioning and installation of the reflector cup 2 and the anti-glare shield 1.

[0060] Furthermore, the surface of the light-transmitting part 11 facing the reflector cup 2 has a supporting boss 112, which surrounds the periphery of the light-mixing surface 111 and abuts against the support platform 22 of the reflector cup 2. This arrangement, by having the supporting boss 112 abut against the support platform 22 of the reflector cup 2, allows the light-mixing surface 111 to be enclosed within a closed cavity. This not only improves the assembly stability between the anti-glare shield 1 and the reflector cup 2 but also ensures that more light source is emitted through the light-transmitting part 11.

[0061] To facilitate assembly between the anti-glare shield 1 and the reflector 2, one of the anti-glare shield 1 and the reflector 2 has a first latching protrusion 13, and the other has a first latching groove 223 that engages with the first latching protrusion 13. In this example, the anti-glare shield 1 also has a first latching protrusion 13, which is connected to the surface of the light-transmitting portion 11 facing the reflector 2; the reflector 2 also has a first latching groove 223 that engages with the first latching protrusion 13. Specifically, the light-transmitting portion 11 of the anti-glare shield 1 has two first latching protrusions 13 on each side in its width direction. Similarly, the number and arrangement of the first latching grooves 223 are the same as those of the first latching protrusions 13. It is understood that in other examples, those skilled in the art can design the number and arrangement of the first latching protrusions 13 and the first latching grooves 223 according to specific circumstances. The number is not limited to two on each side; it can also be three, four, five, or more. These will not be illustrated here.

[0062] When assembling the linear lights, first assemble the anti-glare cover 1 and the reflector cup 2, and then fix the combination of the two directly on the reflector cup bracket 3. There is no need to add an assembly structure between the anti-glare cover 1 and the outer shell. This not only simplifies the structure of the outer shell, but also avoids the problem of the anti-glare cover 1 and the outer shell being unable to be assembled due to assembly tolerances and other reasons.

[0063] Figure 5 This is a partial structural schematic diagram of the reflector cup holder 3 provided in an embodiment of this application. For example... Figure 5 Combination Figure 4 and Figure 2 As shown, the reflector cup bracket 3 is connected to the side of the reflector cup 2 facing away from the anti-glare cover 1. Exemplarily, the reflector cup bracket 3 has a second latching protrusion 211, and the reflector cup 2 has a second latching groove 31 that engages with the second latching protrusion 211. The connection between the reflector cup 2 and the reflector cup bracket 3 is achieved through the engagement of the second latching protrusion 211 and the second latching groove 31, which can improve assembly efficiency and reduce assembly costs.

[0064] The reflector cup bracket 3 also has a limiting structure 32. When assembling the reflector cup 2 and the reflector cup bracket 3, the two ends only need to be roughly aligned. Under the guidance of the second slot 31 on the reflector cup bracket 3 and the limiting structure, the reflector cup 2 and the reflector cup bracket 3 can be quickly installed in place, achieving a blind installation effect and thus quickly improving assembly efficiency.

[0065] In other examples, as long as one of the reflector cup 2 and the reflector cup bracket 3 has a second latching protrusion 211 and the other has a second latching groove 31 that engages with the second latching protrusion 211, the connection between the reflector cup 2 and the reflector cup bracket 3 can be achieved. Examples will not be given here.

[0066] In this example, such as Figure 4 Combination Figure 1 As shown, the reflector cup holder 3 has second latching protrusions 211 on both sides of its width direction, with four second latching protrusions 211 on each side. Similarly, the number and arrangement of the second latching slots 31 are the same as those of the second latching protrusions 211. It is understood that in other examples, those skilled in the art can design the number and arrangement of the second latching protrusions 211 and the second latching slots 31 according to specific circumstances. The number is not limited to two on each side, but can also be two, three, five or more, which will not be illustrated here.

[0067] Furthermore, in this application, the light-transmitting part 11 and the anti-glare part 12 are designed as a single unit. The entire anti-glare cover 1 can be embedded inside the housing 5 of the linear light, or it can be partially external (specifically, the anti-glare part 12) outside the housing 5. This can be matched with different installation scenarios, and the assemblers can choose according to the actual installation environment, thus expanding the application scenarios of the linear light.

[0068] Figure 6 This is a schematic diagram of the embedded installation structure of the linear light provided in an embodiment of this application. Figure 6 As shown, the end face of the anti-glare cover 1 away from the reflector cup 2 is roughly flush with the end face of the outer shell 5, that is, the entire anti-glare cover 1 is completely embedded in the outer shell 5. At this time, the user cannot see the anti-glare part 12 of the anti-glare cover 1 from the side of the outer shell 5. The appearance of the outer shell 5 is the overall appearance of the linear light, which can improve the aesthetics of the linear light.

[0069] Figure 7 This is a schematic diagram of the external mounting structure of the linear light component provided in an embodiment of this application. For example... Figure 7 As shown, the anti-glare part 12 of the anti-glare cover 1 abuts against the end face of the outer shell 5 on the side facing the reflector cup 2. That is, the anti-glare part 12 of the anti-glare cover 1 is placed outside the outer shell 5. At this time, the user can see the structure of the anti-glare part 12 from the side of the outer shell 5. In other words, the anti-glare part 12 of the anti-glare cover 1 and the outer shell 5 together constitute the appearance of the linear light. Due to the V-shaped structure of the anti-glare part 12 of the anti-glare cover 1, the internal components of the linear light can be covered, thereby improving the overall aesthetics of the linear light.

[0070] In summary of the above two examples, for the linear lights of the anti-glare cover 1 described above, according to the structure and size of the housing 5, they can be selectively installed in an internal manner or partially externally, and both can have high ornamental value and enhance user favorability. The linear lights provided by this application have the characteristics of beautifying the space, flexible lighting, intelligent convenience, safety and practicality. They can strengthen the sense of design, adapt to various styles, supplement the basic light, highlight key areas. They can not only achieve linkage control to meet the needs of modern life, but also guide the path, hide defects, and enhance user favorability.

[0071] In addition, the linear lights provided by this application have the following beneficial effects compared with the linear lights in the related art: 1) The appearance surface of the anti-glare cover 1 is not easy to hide dust and is easy to clean; 2) The anti-glare cover 1 integrates the anti-glare function and the lens function, and there is no need to additionally set a lens, which can reduce the assembly link and improve the assembly efficiency; 3) The anti-glare cover 1 can be compatible with embedded installation and external installation, and can be selectively installed internally or externally. When the anti-glare part 12 of the anti-glare cover 1 is externally installed, it can be used as a decorative part of the whole lamp, improving the aesthetic degree of the whole lamp; 4) It is convenient to position and assemble between the anti-glare cover 1 and the reflector cup 2, and no positioning fixture is required, reducing the assembly difficulty.

[0072] The above shows and describes the basic principles, main features and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of this application.
