[0002] Linear lights are a type of lighting used to display architectural outlines. They are compact and easy to install, and are applied in various confined spaces. Existing linear lights include a housing, a light source board, and a reflector, such as CN202420510614.3, a new type of linear light. Although they can meet general usage needs, they still have certain technical shortcomings. For example, the use of a reflector can cause the brightness of the light in the center to be much greater than that at the edges, resulting in glare. Moreover, their overall structure is relatively large, which is not conducive to concealed or recessed installation, nor is it conducive to adjusting the angle of the light source board, thus affecting their applicability to some extent. Utility Model Content

[0003] The purpose of this invention is to provide a linear light with an adjustable illumination angle that has a reasonable structural design and is easy to adjust.

[0004] The technical solution to achieve the purpose of this utility model is an adjustable illumination angle linear light, including a linear light holder with a U-shaped cross section. The linear light holder is provided with a light source plate and a light-transmitting silicone plate.

[0006] The end face of the shaft is provided with a groove in the shape of a Chinese character. The shaft rotates on the supporting protrusion and causes the light source plate to tilt at an angle.

[0007] The upper part of the symmetrical inner wall of the linear lamp holder is provided with a strip-shaped groove in the same direction as the extension of the linear lamp holder.

[0008] The symmetrical edges of the light-transmitting silicone plate are positioned within the strip-shaped slot, and the light-receiving surface of the light-transmitting silicone plate is a semi-circular concave surface.

[0009] The light from the light source plate enters the light-transmitting silicone plate through the semi-circular concave surface and shines outward from the light-emitting surface of the light-transmitting silicone plate.

[0010] A further preferred embodiment is that the inner wall of the opening of the linear lamp holder is a trumpet-shaped opening with the top tilted away from the center line.

[0011] A further preferred embodiment is that a rubber ring is provided at the connection between the shaft and the supporting protrusion, and the shaft rotates within the supporting protrusion and is limited by the friction of the rubber ring.

[0021] 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.

[0022] Example

[0023] See Figures 1 to 3 As shown, an adjustable illumination angle linear light includes a linear light holder 1 with a U-shaped cross-section. The linear light holder is provided with a light source plate 2 and a light-transmitting silicone plate 3. The light from the light source plate is irradiated outward through the light-transmitting silicone plate. In this embodiment, the light source plate is a conventional structure of the prior art, and it is simply applied.

[0024] Furthermore, in this embodiment, the recessed area of ​​the linear lamp holder is provided with supporting protrusions 4 at both ends. These supporting protrusions can be fixed with screws or integrally molded. A shaft 5 is provided within the recessed area of ​​the linear lamp holder, with both ends rotatably connected to the supporting protrusions. The shaft is made of insulating plastic or silicone. To improve the connection stability of the shaft, a rubber ring 13 is provided at the connection between the shaft and the supporting protrusions. The shaft rotates within the supporting protrusions and is limited by the friction of the rubber ring. During installation, the shaft can be rotated to change the illumination angle of the light source board according to the required illumination angle. After rotation, the rubber ring provides a limiting force, ensuring a stable and reliable position after angle adjustment.

[0025] In this embodiment, a plurality of radial support plates 6 are provided on the shaft, and the light source plate is attached to the radial support plates and fixed by screws; the above structure can ensure the stability and reliability of the installation of the light source plate.

[0026] Furthermore, the end face of the shaft is provided with a straight groove 7. The shaft rotates on the supporting protrusion, causing the light source plate to tilt. The straight groove is mainly to facilitate the rotation of the shaft using tools. Additionally, the upper part of the symmetrical inner wall of the linear lamp holder is provided with a strip-shaped slot 8 in the same direction as the extension of the linear lamp holder. During assembly, the symmetrical edges of the light-transmitting silicone plate are positioned within the strip-shaped slot, and the light-inlet surface of the light-transmitting silicone plate is a semi-circular concave surface 9. The light from the light source plate enters the light-transmitting silicone plate through the semi-circular concave surface and shines outward from the light-outlet surface of the light-transmitting silicone plate. The semi-circular concave surface ensures that even after adjusting the angle of the light source plate, the light can still shine outward from the semi-circular concave surface, guaranteeing the effectiveness and reliability of the illumination.

[0027] Furthermore, in this embodiment, the inner wall of the opening of the linear lamp holder is a trumpet-shaped opening 10 with its top tip inclined away from the center line. This trumpet-shaped opening increases the illumination range at the opening, thereby ensuring the range and effectiveness of the emitted light when the angle is adjusted.

[0028] In this embodiment, end caps 11 are fixed to both ends of the linear lamp holder with screws, and one end cap is provided with a power connection terminal 12 connected to the light source board. This ensures the effectiveness and reliability of the power supply. The width of the light source board is 1 / 3 of the width of the recessed area of ​​the linear lamp holder, thereby ensuring the range of angle adjustment.

[0029] This utility model has positive effects: Its structure is rationally designed, with a shaft positioned between the supporting protrusions of the linear lamp holder. The light source plate is fixed on the radial support plate of the shaft for positioning. During installation, the shaft can be rotated as needed to adjust the tilt angle of the light source plate, achieving illumination requirements in different directions. Furthermore, the light is prevented from shining directly through the translucent silicone plate, avoiding excessively bright central light and improving the lighting effect. Simultaneously, the light-receiving surface of the translucent silicone plate is a semi-circular concave surface, allowing for illumination in different directions after adjusting the angle of the light source plate, thus expanding its applicability and meeting installation needs in various situations.

[0030] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
