Wide-angle linear lamp

Abstract

The utility model discloses a wide-angle linear lamp which is mainly composed of a lamp shell, a lampshade and a light source plate. The lamp shell is internally provided with a light-emitting area. The two sides of the light-emitting area are designed with reflective inclined planes A and B with different heights and angles. Through asymmetric reflection, the light is diffused to a super large angle, realizing wide-angle lighting. The glass fiber plate of the light source plate is clamped in the lamp shell. After the emitted light is reflected, it is mixed again by the light mixing inclined plane of the lampshade, forming a high-quality light band with uniform and soft light and no glare. All the components are connected by clamping, and are provided with mounting brackets, realizing quick assembly, flexible customization and stable installation, and being convenient for maintenance. The whole achieves the comfortable visual effect of "seeing light but not seeing lamp".

Description

Technical Field

[0001] This utility model relates to the field of lamp body technology, specifically a wide-angle linear lamp. Background Technology

[0002] Linear lights are widely used in basic lighting, accent lighting, and ambient lighting in homes, commercial spaces, and offices due to their simple design, soft light, and flexible layout. Traditional linear lights typically include a lamp housing, a light source board inside the lamp housing, and a lampshade covering the opening of the lamp housing.

[0003] In existing technologies, to achieve a wider light emission angle and avoid the visual abruptness caused by a narrow light spot, common practices include setting up a simple reflective surface or using a lampshade with a diffusion effect, such as a frosted or matte finish. However, these solutions all have certain limitations:

[0004] First, the simple single-reflective surface structure has limited control over light, making it difficult to distribute light evenly over a wide angle range. This can easily lead to uneven light spots, with bright areas near the center of the lamp and dark areas on both sides, known as "broken bands" or "grainy appearance," which affects the quality of light output. Second, if only a highly diffused lampshade is used to achieve light spot fusion, although the grainy appearance can be blurred to some extent, it will cause a significant loss of light, resulting in a reduction in the overall luminous efficacy of the lamp, and it is still difficult to completely eliminate the dark areas on both sides. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a wide-angle linear lamp with wide-angle illumination and high lighting comfort.

[0006] The technical solution adopted by this utility model to achieve the above objectives is: a wide-angle linear lamp, including a lamp housing, a lamp shade, and a light source board. The lamp housing has a light-emitting area inside, and the top of the lamp housing adopts an open structure. A reflective inclined surface A is provided on one side of the light-emitting area inside the lamp housing, and a reflective inclined surface B is provided on the other side of the light-emitting area inside the lamp housing. The light source board is snapped into the bottom of the reflective inclined surfaces A and B in the light-emitting area. The lamp shade is snapped into the top of the lamp housing, and a light-mixing inclined surface is provided on the lamp shade.

[0007] The above technical solution has the following characteristics:

[0008] The height of the reflective inclined plane A is greater than the height of the reflective inclined plane B, the reflective inclined plane A faces the light mixing inclined plane, and the tilt angle of the reflective inclined plane A is greater than the tilt angle of the reflective inclined plane B.

[0009] In the above technical solution, in order to realize the installation of the light source board, a snap-fit ​​groove A is provided in the light-emitting area, and the light source board is snapped into the snap-fit ​​groove A;

[0010] In addition, a heat dissipation area is provided at the bottom of the card slot A to dissipate heat from the light source board;

[0011] Furthermore, the light source board includes a fiberglass board and an LED light strip fixedly connected to the fiberglass board, with the fiberglass board snapped into the snap-fit ​​groove A.

[0012] In the above technical solution, the structure of the lampshade is as follows:

[0013] The lampshade includes a beveled part and a snap-fit ​​part A fixedly connected to both sides of the beveled part. The light mixing bevel is provided on the beveled part, and the top of the lamp housing is provided with a snap-fit ​​groove B. The snap-fit ​​part A snaps into the snap-fit ​​groove B.

[0014] In the above technical solution, in order to facilitate the installation of the lamp housing, a mounting bracket is snapped into the bottom of the lamp housing;

[0015] Furthermore, the mounting bracket includes a mounting part, a snap-fit ​​part B, a support part, and an elastic part. The snap-fit ​​part B and the support part are fixedly connected to the inner side of the mounting part, and the elastic part is provided on the top of the mounting part.

[0016] The lamp housing is provided with a snap-fit ​​groove C, the snap-fit ​​part B snaps into the snap-fit ​​groove C, the support part abuts against the bottom surface of the lamp housing, and the elastic part abuts against the side wall of the lamp housing.

[0017] In the above technical solution, the lamp housing is fixedly connected to end caps at both ends by bolts.

[0018] The beneficial effects of this utility model are:

[0019] 1. The light emitted from the light source board is focused by reflective inclined surfaces A and B, and then mixed on the light mixing inclined surface of the lampshade. After being reflected by reflective surfaces A and B, the light is refracted and diffused again when it hits the light mixing inclined surface. This process can further eliminate dark areas, light spots and graininess, and merge the point light sources emitted by multiple LED beads into a very continuous, uniform and soft light band. This makes the lampshade form a high-efficiency light-emitting surface with uniform light emission, which greatly improves the light quality. At the same time, it avoids glare caused by direct light shining into people's eyes. All light is reflected and refracted, and the light source is perfectly hidden, achieving a high-end "see the light but not the lamp" visual comfort effect.

[0020] 2. The height of reflective slope A is greater than that of reflective slope B. Reflective slope A faces the light mixing slope. The tilt angle of reflective slope A is greater than that of reflective slope B. The reflective slope A is higher and has a steeper angle. Its main function is to receive and strongly reflect the light emitted by the light source panel that is directed away from the central area, and to "push" these lights to a wider angle. Reflective slope B is shorter and has a gentler angle. It is responsible for processing the light that is directed near the center and providing soft supplementary lighting. The two together "disperseed" the light and guide it to a very large light output angle to form wide-angle lighting.

[0021] 3. The lamp housing, lampshade, light source board, and mounting bracket are connected by snap-fit ​​joints. This structure greatly simplifies the assembly process, improves production efficiency, and reduces labor costs. It also facilitates quick disassembly and replacement during future maintenance.

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-3A wide-angle linear lamp includes a lamp housing 100, a lamp shade 300, and a light source board 200. The lamp housing 100 has a light-emitting area 101 inside, and the top of the lamp housing 100 has an open structure. A reflective slope A102 is provided on one side of the light-emitting area 101 inside the lamp housing 100, and a reflective slope B103 is provided on the other side of the light-emitting area 101 inside the lamp housing 100. The height of reflective slope A is greater than the height of reflective slope B, and the tilt angle of reflective slope A is greater than the tilt angle of reflective slope B. In this embodiment, the height of reflective slope A102 is twice the height of reflective slope B103, the tilt angle of reflective slope A102 is 76°, and the tilt angle of reflective slope B103 is 66°.

[0028] Furthermore, a light source board 200 is snapped into the bottom of the reflective slopes A102 and B103 within the light-emitting area 101. Specifically, a snap-in groove A104 is provided within the light-emitting area 101, and the light source board 200 is snapped into the snap-in groove A104. In addition, a heat dissipation area 107 is provided at the bottom of the snap-in groove A104 to dissipate heat from the light source board 200. Further, the light source board 200 includes a fiberglass board 201 and an LED light strip 202 fixedly connected to the fiberglass board 201. The fiberglass board 201 is snapped into the snap-in groove A104.

[0029] Furthermore, a lampshade 300 is snapped onto the top of the lamp housing 100. Specifically, the lampshade 300 includes a beveled portion 301 and snap-fit ​​portions A302 fixedly connected to both sides of the beveled portion 301. A light-mixing bevel is provided on the beveled portion 301, and the aforementioned reflective bevel A faces the light-mixing bevel. A snap-fit ​​groove B105 is provided on the top of the lamp housing 100, and the snap-fit ​​portion A302 snaps into the snap-fit ​​groove B105.

[0030] Furthermore, to facilitate the installation of the lamp housing 100, a mounting bracket 400 is snapped onto the lamp housing 100. Specifically, the mounting bracket 400 includes a mounting part 401, a snap-fit ​​part B402, a support part 403, and an elastic part 404. That is, the snap-fit ​​part B402 and the support part 403 are fixedly connected to the inner side of the mounting part 401, the elastic part 404 is provided at the top of the mounting part 401, the lamp housing 100 is provided with a snap-fit ​​groove C106, the snap-fit ​​part B402 is snapped into the snap-fit ​​groove C106, the support part 403 abuts against the bottom surface of the lamp housing 100, and the elastic part 404 is attached to the bottom surface of the lamp housing 100. The side wall of the lamp housing 100 abuts against the lamp housing 100. This structure provides the main mechanical locking through the snap-fit ​​part B402 and the snap-fit ​​groove C106, and supports the weight of the lamp. The support part 403 provides upward support for the lamp, preventing the lamp housing 100 from sinking or deforming due to gravity or vibration, and ensuring the flatness of the installation. The elastic part 404 abuts against the side wall of the lamp housing 100, so that the elastic part 404 can use its elastic deformation to eliminate the assembly gap between the mounting bracket 400 and the lamp housing 100, prevent the lamp from loosening or shaking, avoid noise, and at the same time, it can adapt to small dimensional tolerances, making the installation smoother.

[0031] Furthermore, the lamp housing 100 is fixedly connected to end caps 500 at both ends by bolts. This allows the lamp housing 100 to be cut to the required length and the end caps 500 to seal both ends, achieving flexible length customization. At the same time, the end caps 500 also facilitate the connection and concealment of internal wiring.

[0032] In summary, in this embodiment, the reflective ramp A102 is higher and has a steeper angle. Its main function is to receive and strongly reflect the light emitted by the light source plate 200 that is directed away from the central area, "pushing" these lights to a wider angle. The reflective ramp B103 is shorter and has a gentler angle, so it is responsible for processing the light directed near the center and providing soft supplementary lighting. The two together "scatter" the light and guide it to a very large light output angle to form wide-angle lighting.

[0033] In addition, after being reflected and focused by reflective inclined surfaces A102 and B103, the light is then mixed on the light mixing inclined surface of the lampshade 300. This process causes refraction and diffuse reflection again, which further eliminates dark areas, light spots and graininess, and merges the point light sources emitted by multiple LED beads into a very continuous, uniform and soft light band. This makes the lampshade 300 a high-efficiency light-emitting surface with uniform light emission, which greatly improves the light quality. At the same time, it avoids glare caused by direct light shining into the eyes. All light is reflected and refracted, and the light source is perfectly hidden, achieving a high-level "see the light but not the lamp" visual comfort effect.

[0034] Furthermore, the lamp housing 100, lamp shade 300, light source board 200, and mounting bracket 400 are connected by a snap-fit ​​mechanism. This structure greatly simplifies the assembly process, improves production efficiency, and reduces labor costs. It also facilitates quick disassembly and replacement during future maintenance.
