Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an anti-glare lampshade. Background Technology

[0002] Currently, lighting sources typically employ optical modules to improve light emission efficiency and prevent glare. These optical modules consist of an optical anti-glare shield and a lens.

[0003] Currently, the anti-glare shields used on the market are opaque, and most products can only be black. However, since black surfaces absorb light relatively well, most of the light that travels to the inner wall of the anti-glare shield is not reflected back, resulting in a relatively low light emission efficiency. If the anti-glare shield is made transparent, although the light emission efficiency will be improved, it will not achieve the anti-glare effect. Therefore, it is impossible to balance the anti-glare effect and the light emission efficiency.

[0004] Therefore, there is an urgent need for an anti-glare lampshade to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an anti-glare lampshade with good anti-glare effect and high light output efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution: On the one hand, an anti-glare lamp cover is provided, the anti-glare lamp cover includes an anti-glare cover body, the anti-glare cover body is a transparent cover body or a non-transparent cover body including a light inlet, a light outlet and a light path channel; When the anti-glare cover is a transparent cover, the outer surface of the anti-glare cover away from the optical path channel is provided with an anti-glare texture. The anti-glare texture is one or more of the following: a Thésen polygon, a quadrilateral, a corrugated shape, a honeycomb shape, or other regular or irregular polygons, which are used to form a number of refractive surfaces at different angles on the outer surface of the anti-glare cover away from the optical path channel. When the anti-glare cover is a non-transparent cover, the anti-glare cover has color and a reflective coating is provided on the inner wall surface of the light path channel.

[0007] Optionally, when the anti-glare cover is a transparent cover, the surface of the anti-glare cover is away from the surface of the optical path channel, and / or, the inner wall surface of the optical path channel is provided with a colored coating. When the anti-glare cover is a non-transparent cover, the base of the anti-glare cover has a base color to form a non-transparent colored cover; Alternatively, the anti-glare cover may be coated with the color coating to form a non-transparent colored cover.

[0008] Optionally, the anti-glare cover is further provided with a snap-fit ​​component, which includes a connecting plate and a snap-fit ​​structure. One end of the connecting plate is connected to the light inlet of the anti-glare cover, and the other end of the connecting plate is connected to the snap-fit ​​structure.

[0009] Optionally, a limiting notch is provided on the connecting plate, and the light inlet of the anti-glare cover is provided with a limiting protrusion extending in a direction away from the light outlet, and the limiting protrusion is inserted into the limiting notch.

[0010] Optionally, the anti-glare lamp cover further includes an outer perimeter dam, which is continuously arranged around the circumferential edge of the light outlet and extends along the direction of the light inlet, and the anti-glare cover is enclosed within the outer perimeter dam.

[0011] Optionally, the outer perimeter dam and the anti-glare shield are connected via a curved structure.

[0012] Optionally, the anti-glare shield or the outer perimeter dam has a top flat surface on the side facing away from the light outlet.

[0013] Optionally, when the top abutting plane is provided on the anti-glare cover, the anti-glare cover has an abutting barrier extending along the direction away from the light outlet on the side of the light inlet, and the top abutting plane is located on the side of the abutting barrier away from the light outlet.

[0014] Optionally, the cross-section of the anti-glare shield is circular, rectangular, or other polygonal.

[0015] Optionally, when the cross-section of the anti-glare cover is circular, the diameter of the anti-glare cover gradually increases from the light inlet to the light outlet. Alternatively, when the cross-section of the anti-glare shield is rectangular, the cross-sectional area of ​​the anti-glare shield gradually increases from the light inlet to the light outlet.

[0016] The beneficial effects of this utility model are: This utility model provides an anti-glare lampshade, which includes an anti-glare cover body composed of a light inlet, a light outlet, and a light path channel. When the anti-glare cover body is transparent, one or more anti-glare textures, such as Thiessen polygons, quadrilaterals, corrugated shapes, honeycomb shapes, or other regular or irregular polygons, are formed on the outer surface of the anti-glare cover body facing away from the light path channel. This creates numerous refractive surfaces at different angles on the outer surface of the anti-glare cover body. When light hits the anti-glare lampshade through the light inlet, it passes through numerous refractive surfaces at different angles to adjust the light path of large-angle light. On the one hand, this reduces the light penetrating from the inside of the anti-glare cover body to the outside, preventing the anti-glare cover from appearing excessively bright in some areas and causing eye damage, thus enhancing the anti-glare effect. On the other hand, it allows the light to be refocused and flow out through the light outlet of the light path channel, reducing brightness loss and improving light output efficiency. Thus, while ensuring light output efficiency, the anti-glare effect is also taken into account. In addition, because the light path is formed by the refraction surfaces at many different angles, the anti-glare lamp cover has a dimly lit area, a bright area and a darker area when viewed from different angles, thus forming a starry lighting effect, making the overall appearance of the anti-glare lamp cover dazzling and greatly improving its aesthetics. When the anti-glare cover is non-transparent, a reflective coating is applied to the inner wall surface of the optical path channel to reduce the light absorption rate and improve the light output efficiency, thereby ensuring both the anti-glare effect and the light output efficiency.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0023] Currently, lighting sources typically employ optical modules to improve light emission efficiency and prevent glare. These optical modules consist of an optical anti-glare shield and a lens.

[0024] Because the anti-glare shields currently used on the market are opaque, most products can only be black. However, since black surfaces absorb more light, most of the light that travels to the inner wall of the anti-glare shield is not reflected back, resulting in a relatively low light emission efficiency. If the anti-glare shield is made transparent, although the light emission efficiency will be improved, it will not be able to achieve the anti-glare effect, and without light control treatment, the improvement in light emission efficiency will be limited.

[0025] Therefore, in order to improve the anti-glare effect and increase the light output efficiency, this embodiment provides an anti-glare lampshade.

[0026] like Figures 1 to 4 As shown, the anti-glare lamp cover includes an anti-glare cover body 1, which is a transparent or non-transparent cover body including a light inlet 11, a light outlet 12, and a light path channel 13. When the anti-glare cover 1 is a transparent cover, an anti-glare texture 14 is provided on the outer surface of the anti-glare cover 1 away from the light path channel 13. The anti-glare texture 14 is one or more of the following: a Thésen polygon, a quadrilateral, a corrugated shape, a honeycomb shape, or other regular or irregular polygons, in order to form a number of refractive surfaces at different angles on the outer surface of the anti-glare cover 1 away from the light path channel 13. When the anti-glare cover 1 is a non-transparent cover, the anti-glare cover 1 has color and a reflective coating is provided on the inner wall surface of the light path channel 13.

[0027] The anti-glare lampshade includes an anti-glare cover 1 consisting of a light inlet 11, a light outlet 12, and a light path channel 13. When the anti-glare cover 1 is a transparent cover, one or more anti-glare textures 14, such as Thésen polygons, quadrilaterals, corrugated shapes, honeycomb shapes, or other regular or irregular polygons, are formed on the outer surface of the anti-glare cover 1 away from the light path channel 13. This creates numerous refractive surfaces at different angles on the outer surface of the anti-glare cover 1 away from the light path channel 13. When light hits the anti-glare lampshade through the light inlet 11, it passes through numerous refractive surfaces at different angles to adjust the light path of large-angle light. On the one hand, this reduces the amount of light penetrating from the inside of the anti-glare cover 1 to the outside, preventing the anti-glare cover from appearing excessively bright in some areas and causing eye damage, thus enhancing the anti-glare effect. On the other hand, it allows the light to be refocused and flow out through the light outlet 12 of the light path channel 13, reducing brightness loss and improving light output efficiency. Thus, while ensuring light output efficiency, the anti-glare effect is also taken into account. In addition, because the light path is formed by the refraction surfaces at many different angles, the anti-glare lamp cover has a dimly lit area, a bright area and a darker area when viewed from different angles, thus forming a starry lighting effect, making the overall appearance of the anti-glare lamp cover dazzling and greatly improving its aesthetics. When the anti-glare cover 1 is a non-transparent cover, a reflective coating is provided on the inner wall surface of the light path channel 13 to reduce the light absorption rate when using a non-transparent cover and improve the light output efficiency, thereby ensuring the anti-glare effect while taking into account the light output efficiency.

[0028] In this embodiment, the anti-glare texture 14 applied to the outer surface of the anti-glare cover 1, which is a transparent cover, is an irregular prismatic structure, which forms numerous prismatic protrusions of different sizes on the outer surface of the anti-glare cover 1. The surfaces of each prismatic protrusion form numerous refractive surfaces at different angles on the outer surface of the anti-glare cover 1.

[0029] In this embodiment, the reflective coating applied to the inner wall surface of the light path channel 13 in the anti-glare cover 1, which is a non-transparent cover, is formed by an aluminum plating process. In other embodiments, other materials with reflective properties can also be used for the coating.

[0030] Optionally, when the anti-glare cover 1 is a transparent cover, the surface of the anti-glare cover 1 facing away from the light path channel 13, and / or, the inner wall surface of the light path channel 13 is provided with a colored coating. By providing a colored coating on the surface of the anti-glare cover 1 facing away from the light path channel 13, and / or on the inner wall surface of the light path channel 13, the appearance of the anti-glare lamp cover 1 is made more aesthetically pleasing, and through the light paths of different lines, the visual effect of the anti-glare lamp cover 1 is made more dazzling when in use.

[0031] The location of the color coating can be freely selected according to requirements. In this embodiment, the color coating is set on the surface of the anti-glare cover 1 on the side with the anti-glare texture 14. Furthermore, the specific color of the color coating can be freely selected according to actual needs, such as silver, black, white, gold, green, etc.

[0032] Optionally, when the anti-glare cover 1 is a non-transparent cover, the base of the anti-glare cover 1 has a base color to form a non-transparent colored cover; Alternatively, the anti-glare cover 1 may be coated with a colored layer to form an opaque colored cover. By selecting an anti-glare cover 1 with a base color or by spraying a colored layer onto the anti-glare cover 1, an opaque colored cover is formed. This not only makes the anti-glare cover 1 more aesthetically pleasing, but also allows for better anti-glare performance in different environments by selecting different colors.

[0033] The color of the anti-glare shield 1 can be freely selected according to actual needs, such as silver, black, white, gold, green, etc.

[0034] Optionally, such as Figure 1 , Figure 2 As shown, the anti-glare cover 1 also includes a snap-fit ​​component 15, which comprises a connecting plate 151 and a snap-fit ​​structure 152. One end of the connecting plate 151 is connected to the light inlet 11 of the anti-glare cover 1, and the other end of the connecting plate 151 is connected to the snap-fit ​​structure 152. By providing the snap-fit ​​component 15 on the anti-glare cover 1, it is convenient to assemble the anti-glare cover 1 with the components inside the lamp. The snap-fit ​​component 15 enables a detachable connection, which facilitates disassembly and assembly when replacing or repairing the anti-glare lamp cover. Even if the anti-glare lamp cover is damaged, only the anti-glare lamp cover needs to be replaced, without replacing the entire lamp, thus reducing maintenance costs.

[0035] The form of the snap-fit ​​structure 152 can be freely set according to requirements. When the snap-fit ​​structure 152 is a snap-fit ​​protrusion, the component of the lamp that connects to the anti-glare cover 1 is provided with a snap-fit ​​groove. When the snap-fit ​​structure 152 is a snap-fit ​​groove, the component of the lamp that connects to the anti-glare cover 1 is provided with a snap-fit ​​protrusion. In this embodiment, the snap-fit ​​structure 152 is a snap-fit ​​protrusion. In addition, the number of snap-fit ​​pieces 15 provided on the anti-glare cover 1 can be freely set according to requirements. In this embodiment, when the cross-section of the anti-glare cover 1 is circular, two symmetrically distributed snap-fit ​​pieces 15 are provided on the anti-glare cover 1. When the cross-section of the anti-glare cover 1 is rectangular, four symmetrically distributed snap-fit ​​pieces 15 are provided on the anti-glare cover 1.

[0036] Optionally, such as Figure 3 As shown, a limiting notch is provided on the connecting plate 151, and a limiting protrusion 16 extending in a direction away from the light outlet 12 is provided on the light inlet 11 of the anti-glare cover 1. The limiting protrusion 16 is inserted into the limiting notch. By providing a limiting notch on the connecting plate 151 and setting a limiting protrusion 16 at the light inlet 11 of the anti-glare cover 1, the connection area between the anti-glare cover 1 and the snap-fit ​​member 15 is increased by using the insertion of the limiting protrusion 16 and the limiting notch, thus ensuring the connection strength after the two are connected.

[0037] Optionally, such as Figure 3 , Figure 4 As shown, the anti-glare lamp cover also includes an outer perimeter dam 2, which is continuously arranged around the circumferential edge of the light outlet 12 and extends towards the light inlet 11. The anti-glare lamp cover 1 is enclosed within the outer perimeter dam 2. By setting the outer perimeter dam 2 around the outside of the anti-glare lamp cover 1, the light leaking from the light inlet 11 of the anti-glare lamp cover 1 is reduced, thereby reducing glare.

[0038] Furthermore, such as Figure 3 , Figure 4 As shown, the outer perimeter dam 2 and the anti-glare shield 1 are connected by a curved structure 3. By setting the curved structure 3 between the outer perimeter dam 2 and the anti-glare shield 1, the light path of the light incident on the outer perimeter dam 2 is controlled, so that the light leaking from the light inlet 11 of the anti-glare shield 1 is refracted towards the ceiling through the curved structure 3, avoiding entering the eyes, thereby further reducing glare. The curved structure 3 can be a rounded corner or a curved surface.

[0039] Optionally, such as Figure 1 , Figure 3As shown, the anti-glare cover 1 or the outer perimeter dam 2 has a top abutment plane 4 on the side opposite to the light outlet 12. By providing the top abutment plane 4 on the side opposite to the light outlet 12 of the anti-glare cover 1 or the outer perimeter dam 2, it is possible to achieve top positioning when assembling with other parts of the lamp, which facilitates assembly. On the other hand, since the anti-glare lamp cover in this embodiment is manufactured by integral molding with a mold, the top abutment plane 4 facilitates the demolding of the mold ejector pins, avoiding contact between the mold ejector pins and the area with the anti-glare texture 14 during demolding, which could damage the anti-glare texture 14.

[0040] In this embodiment, since the anti-glare lamp cover is manufactured by integral molding with a mold, the texture structure used to prepare the anti-glare texture 14 on the mold can be set on the rear mold or the front mold, and its specific setting position can be freely selected according to the requirements.

[0041] Optionally, such as Figure 1 As shown, when the top abutment plane 4 is provided on the anti-glare cover 1, the anti-glare cover 1 has an abutment barrier 17 extending from the side of the light inlet 11 away from the light outlet 12, and the top abutment plane 4 is located on the side of the abutment barrier 17 away from the light outlet 12. Since the anti-glare cover 1 can be provided with an outer perimeter barrier 2 or not, when the outer perimeter barrier 2 is not provided, the anti-glare texture 14 is protected by the abutment barrier 17 on the anti-glare cover 1, so that the ejector pin can act on the abutment barrier 17 to achieve demolding.

[0042] In other embodiments, such as Figure 3 As shown, if an outer perimeter dam 2 is provided, since the outer perimeter dam 2 is continuously arranged around the circumferential edge of the light outlet 12 and extends towards the light inlet 11, the ejector pin can directly rest against the outer perimeter dam 2, thereby avoiding damage to the anti-glare texture 14 by the ejector pin.

[0043] Optionally, such as Figure 1 , Figure 3 As shown, the cross-section of the anti-glare shield 1 is circular, rectangular, or other polygonal. By making the cross-section of the anti-glare shield 1 circular, rectangular, or other polygonal, it can be adapted to different shapes and types of lamps.

[0044] Optionally, such as Figure 1 As shown, when the cross-section of the anti-glare shield 1 is circular, the diameter of the anti-glare shield 1 gradually increases from the light inlet 11 to the light outlet 12. By gradually increasing the cross-sectional area of ​​the light path channel 13, the amount of light penetrating the outer wall from the inner wall of the anti-glare shield 1 can be reduced, the amount of light emitted from the light outlet 12 of the anti-glare shield 1 can be increased, and the lighting effect can be enhanced.

[0045] Optionally, such as Figure 3As shown, when the cross-section of the anti-glare shield 1 is rectangular, the cross-sectional area of ​​the anti-glare shield 1 gradually increases from the light inlet 11 to the light outlet 12. By gradually increasing the cross-sectional area of ​​the light path channel 13, the amount of light penetrating the outer wall from the inner wall of the anti-glare shield 1 can be reduced, the amount of light emitted from the light outlet 12 of the anti-glare shield 1 can be increased, and the lighting effect can be enhanced.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
