Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, specifically relating to a soft-light anti-glare linear lamp. Background Technology

[0002] Linear lighting fixtures, also known as wall washer lights, are mostly used in outdoor decorative lighting and are generally installed on the exterior of building curtain walls. However, the beam of linear lighting fixtures is diffused, meaning it can project onto the wall surface that needs lighting as well as the surrounding environment that does not need lighting, causing serious light pollution. Furthermore, when the light from linear lighting fixtures shines downwards or horizontally into the eyes, it can easily produce dazzling glare.

[0003] In addition, when a linear beam of light is projected onto the wall surface, if the wall surface is smooth and without particles, the light cannot form a diffuse reflection and uniform lighting effect on the wall surface. Strong light spots will also be formed in the direction of the light intensity in the center of the light, resulting in inconsistent brightness and poor overall uniformity on the wall surface. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a soft light anti-glare linear lamp.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A soft-light anti-glare linear lamp includes a lamp body with a linear profile structure. An internal circuit board is provided on the lamp body, and multiple LED light sources are evenly arranged along the length of the lamp body on the circuit board. A lens is provided on the outer side of each LED light source. A light-transmitting plate and a grid cover are sequentially installed on the light-emitting side of the lamp body from the inside out. Multiple light-shielding grid plates are evenly arranged along the length of the lamp body inside the grid cover. Each light-shielding grid plate corresponds to one of the LED light sources and is located directly above the LED light source. Each light-shielding grid plate has a horizontal portion and an inclined portion. The horizontal portion is connected to the side of the inclined portion away from the LED light source, and the plane of the horizontal portion is perpendicular to the optical axis center of the LED light source. The inclined portion is inclined and forms an angle of 135 degrees to 155 degrees with the horizontal portion.

[0007] As a preferred embodiment of this utility model, the material of the light-shielding grille is stainless steel, the inner side of the light-shielding grille is a smooth, silver-white reflective surface, and the outer side of the light-shielding grille is a dark gray reflective surface.

[0008] As a preferred embodiment of this utility model, the light-shielding grille covers the lens on the circuit board through its forward projection.

[0009] As a preferred embodiment of the present invention, the lamp body includes a middle partition and first side plates connected to both sides of the middle partition in the width direction. The middle partition divides the space between the two first side plates into a first groove for accommodating the circuit board, the LED light source, the lens and the light-transmitting plate, and a second groove for connecting the mounting bracket. The grille cover is disposed on the outside of the first groove.

[0010] As a preferred embodiment of this utility model, the two side walls of the first groove are respectively provided with slots at the bottom of the groove for matching the two sides of the circuit board.

[0011] As a preferred embodiment of this utility model, the two side walls of the first groove are respectively provided with recesses at the groove opening for the light-transmitting plate to be embedded.

[0012] As a preferred embodiment of the present invention, the grille cover includes a second side plate connected to both sides of the light-shielding grille in the width direction, and the second side plates on both sides are respectively engaged with the first side plates on both sides.

[0016] As a preferred embodiment of this utility model, the lamp body is provided with cover plates at both ends.

[0017] Compared with the prior art, the soft-light anti-glare linear lamp of this utility model has the following advantages:

[0018] This utility model's soft-light anti-glare linear luminaire places each inclined light-shielding grille directly above each LED light source. This ensures that the light emitted by each LED light source undergoes at least two reflections between adjacent light-shielding grilles before exiting the luminaire, allowing the light to evenly illuminate the entire environment, reducing glare and improving visual comfort. Simultaneously, the lens ensures that each LED light source effectively illuminates its corresponding light-shielding grille, effectively reducing diffused light directly exiting the luminaire and enhancing the anti-glare effect. Furthermore, the soft-light anti-glare linear luminaire incorporates a horizontal section on the light-shielding grille to prevent some light from being directly emitted from the luminaire after a single reflection from the inclined surface, maintaining the anti-glare effect. Finally, when the linear beam is projected onto the illuminated wall, the uniform and soft light is not affected by the smooth, particle-free wall surface, and strong light spots are not formed in the center of the light intensity direction, resulting in consistent brightness and good overall uniformity of the curtain wall.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 3 The lamp shown is a soft-light anti-glare linear lamp, which includes a lamp body 1. The lamp body 1 has a linear profile structure. The lamp body 1 has a circuit board 2 inside. The circuit board 2 has a plurality of LED light sources 3 evenly arranged along the length of the lamp body 1. Each LED light source 3 has a lens 4 on its outer side. The light-emitting side of the lamp body 1 is covered with a light-transmitting plate 5 and a grid cover 6 from the inside to the outside. The grid cover 6 has a plurality of light-shielding grid plates 61 evenly arranged along the length of the lamp body 1. The light-shielding grid plates 61 correspond one-to-one with the LED light sources 3. The light-shielding grid plates 61 are located directly above the LED light sources 3. The light-shielding grid plates 61 have a horizontal part 611 and an inclined part 612. The horizontal part 611 is connected to the side of the inclined part 612 away from the LED light source 3, and the plane of the horizontal part 611 is perpendicular to the optical axis center of the LED light source 3. The inclined part 612 is inclined and the angle formed with the horizontal part 611 is 135 degrees to 155 degrees.

[0027] Therefore, in the soft-light anti-glare linear lamp according to the embodiment of this utility model, each inclined light-shielding grille 61 is correspondingly positioned directly above each LED light source 3, so that the light emitted by each LED light source 3 is reflected at least twice between two adjacent light-shielding grilles 61 before being emitted from the lamp body 1. This allows the light to evenly illuminate the entire environment, reducing glare and improving visual comfort. At the same time, under the action of the lens 4, each LED light source 3 can effectively illuminate the corresponding light-shielding grille 61. The above effectively reduces the amount of diffused light emitted directly from the lamp body 1, improving the anti-glare effect. Furthermore, the soft-light anti-glare linear lamp also incorporates a horizontal section 611 on the light-shielding grille 61 to prevent some light from being reflected directly from the lamp body 1 after a single reflection from the inclined section 612, thus ensuring the anti-glare effect. Finally, when the linear beam is projected onto the illuminated wall, the uniform and soft light will not be affected by the smooth, particle-free wall surface, nor will it form a strong light spot in the direction of the light intensity at the center of the light. The brightness of the curtain wall is consistent, and the overall uniformity is good.

[0028] For example, the light-shielding grille 61 is made of stainless steel. The inner surface of the light-shielding grille 61 is a smooth, silver-white reflective surface, and the outer surface is a dark gray reflective surface. The smooth, silver-white reflective surface is the original color of the stainless steel. Silver-white typically has a high reflectivity, reflecting more light, while the smooth surface provides more uniform light reflection, reducing light scattering and allowing the light to be reflected more concentratedly and brightly onto the outer surface of the light-shielding grille 61. The dark gray reflective surface is a special effect achieved through surface treatment of the stainless steel. Dark gray typically has a low reflectivity, absorbing more light and reducing light reflection to some extent, thus reducing glare. Additionally, the outer surface of the light-shielding grille 61 can be frosted to form a dark gray frosted reflective surface, further reducing direct light reflection and thus reducing glare, making the light softer.

[0029] For example, the light-shielding grille 61 is projected onto the circuit board 2 in a forward direction and covers the lens 4 to ensure the light-shielding area of ​​the light-shielding grille 61.

[0030] For example, in order to enable the lamp body 1 to simultaneously meet the assembly requirements of the built-in light source device and the external grille cover 6 and mounting bracket 7, the lamp body 1 includes a middle partition 11 and first side plates 12 connected to both sides of the middle partition 11 in the width direction. The middle partition 11 divides the space between the two first side plates 12 into a first groove 13 for accommodating the circuit board 2, the LED light source 3, the lens 4 and the light-transmitting plate 5, and a second groove 14 for connecting the mounting bracket 7; wherein, the grille cover 6 is disposed on the outside of the first groove 13.

[0031] For example, to facilitate the installation and fixing of the circuit board 2 in the first groove 13, the two side walls of the first groove 13 are respectively provided with slots 131 at the bottom of the groove for matching the two sides of the circuit board 2. During installation, the circuit board 2 is inserted into the slot 131 from one end of the lamp body 1.

[0032] For example, to facilitate the installation and fixing of the light-transmitting plate 5 on the first groove 13, the two side walls of the first groove 13 are respectively provided with recesses 132 at their groove openings for the light-transmitting plate 5 to be embedded. In a specific implementation, the light-transmitting plate 5 is glued to the recesses 132 with sealant.

[0033] For example, the grille cover 6 includes second side plates 62 connected to both sides of the light-shielding grille 61 in the width direction, and the two second side plates 62 are respectively engaged with the two first side plates 12. In a specific implementation, the end of the second side plate 62 away from the light-shielding grille 61 is provided with a first engaging edge 621 bent inward towards the grille cover 6, and the outer side of the first side plate 12 is provided with a first engaging groove 121 that engages with the first engaging edge 621.

[0034] For example, the second groove 14 is snapped into the mounting bracket 7. In a specific implementation, the two side walls of the second groove 14 are respectively provided with second snap-fit ​​edges 141 bent inward at their groove openings. The mounting bracket 7 includes a base plate 71 and third side plates 72 connected to both sides of the base plate 71 in the width direction. The outer side of the third side plates 72 is respectively provided with second snap-fit ​​grooves 721 that snap into the second snap-fit ​​edges 141. The base plate 71 is provided with mounting holes.

[0035] For example, the lamp body 1 is provided with cover plates 8 at both ends to prevent dust, moisture and other impurities from entering the lamp, thereby protecting the LED strip or other electronic components of the lamp from damage. In a specific implementation, the cover plates are fixed to the lamp body 1 with screws.

[0036] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
