[0002] Linear lights are lighting devices designed specifically to outline the edges of objects, buildings, or other structures. They not only highlight the shape of the illuminated object, but also enhance the sense of space and visual effects. They are suitable for local or contour lighting in various buildings, indoors and outdoors.

[0003] For linear lights with demanding lighting requirements, such as multi-color luminous flux control and light-effect lighting, multiple corresponding LED chips are required on the power board. This results in a larger power board to accommodate multiple electronic components. However, because the power board of existing linear lights is parallel to the light-emitting surface, the only way to accommodate this large power board is to increase the width of the lamp body. This makes it impossible to fit into the small mounting slots on the building surface.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention provides a side-emitting linear light. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only intended to illustrate the present invention and are not intended to limit the present invention.

[0024] See also Figures 1 to 6 As shown, the utility model provides a side-emitting linear lamp, including a lamp body 1, a lampshade 2, a light source board 3 and a reflector 4. An opening 11 is provided on one side of the short side of the lamp body 1, and the lampshade 2 is provided on the opening 11. The light source board 3 is provided on one side of the long side of the lamp body 1. The reflector 4 is provided in the lamp body 1. The reflector 4 is provided with a first arc surface 41 that is concave inward. The first arc surface 41 faces the light source board 3 and reflects the light emitted by the light source board 3 onto the lampshade 2.

[0025] The cross-section of the lamp body 1 is rectangular, with the opening 11 located on one side of the short side of the rectangle, and the light source board 3 located on one side of the long side of the rectangle. The light emitted from the light source board 3 is emitted onto the lampshade 2 through the reflector 4 and emitted from the light-emitting surface of the lampshade 2. By installing the light source board 3 on one side of the long side of the lamp body 1, it is possible to install a larger light source board 3 so that the light source board 3 can accommodate multiple functional electronic components. The light is emitted from one side of the short side of the lamp body 1, which can effectively reduce the width of the lamp body 1 to meet the installation requirements of a small-sized mounting groove on the building installation surface. In addition, the light emitted by the light source board 3 is more uniform after being reflected by the reflector 4, and the first curved surface 41 of the reflector 4 faces the light source board 3, which can collect and converge the light emitted in all directions by the light source board 3, thereby improving the lighting effect of the entire lamp.

[0026] In the above description, the lamp body 1 is made of aluminum, which has a certain rigidity and structural strength to ensure the structural stability of the linear light. The light source board 3 is installed close to the long side of the lamp body 1, which can increase the contact area between the light source board 3 and the lamp body 1, thereby improving the heat dissipation speed.

[0027] In the above, the material of the reflective sheet 4 can be: reflective aluminum foil, reflective aluminum plate, reflective paper, reflective PET sheet, reflective PC sheet, etc. The curvature of the reflective sheet 4 should be designed according to actual application to achieve the goal of reflecting most of the light emitted by the light source panel 3 to the light-emitting surface of the lampshade 2.

[0028] In a preferred embodiment, see Figure 2 、 5The light source board 3 includes a substrate 31, LED patch lamp beads 32 arranged along the length of the substrate 31, and a lens 33 covering the LED patch lamp beads 32. The LED patch lamp beads 32 are non-monochromatic LED lamp beads. The substrate 31 extends along the length of the lamp body 1. All LED patch lamp beads 32 are welded to the substrate 31. All lenses 33 are fixed to the substrate 31 by adhesive, and one lens 33 is provided for each LED patch lamp bead 32. By providing the lens 33, the light-emitting angle of the LED patch lamp beads 32 can be adjusted so that more light is emitted to the reflector 4. The reflector 4 performs a secondary reflection on the light of the LED patch lamp beads 32, so that the light of multiple color temperatures and wavelengths such as RGBW light source, RGB light source, and dual color temperature light source is mixed more fully and evenly, achieving better light mixing and color mixing effects of the linear light.

[0029] In a preferred embodiment, see Figure 2 、 5 Two first mounting grooves 12 are provided on one side of the long side of the lamp body 1, and the two sides of the substrate 31 are correspondingly provided on the two first mounting grooves 12. Through the above arrangement, the light source board 3 is stably installed on one side of the long side of the lamp body 1.

[0030] In a preferred embodiment, see Figure 1 、 2 3. The lampshade 2 is a solid structure. A groove 21 is provided on one side of the lampshade 2 for accommodating the light source board 3. A second curved surface 22 is provided on the side of the lampshade 2 away from the groove 21. The reflector 4 is provided on the second curved surface 22. The light source board 3 is located in the groove 21. Light emitted by the light source board 3 passes through the lampshade 2 to the reflector 4. The reflector 4 reflects most of the light to the light-emitting surface of the lampshade 2, thereby realizing side-emitting light of the linear light.

[0031] In a preferred embodiment, see Figure 4 、 5 6. The lampshade 2 is a thin-walled structure. A curved plate 13 is provided on the side of the lamp body 1 away from the light source board 3. The reflector 4 is provided on the curved plate 13. Specifically, the lamp body 1 and the curved plate 13 are an integrally extruded structure. The light source board 3 emits light, and the reflector 4 reflects most of the light to the light-emitting surface of the lampshade 2, thereby realizing the side-emitting light of the linear light.

[0032] In the above description, the long side of the lamp body 1 is used to install the light source board 3, and the short side of the lamp body 1 is used to emit light. In actual applications, according to lighting requirements, multiple functional electronic components can be placed on the light source board 3. By increasing the width of the long side of the lamp body 1, the light source board 3 of the corresponding size can be installed. At the same time, there is no need to increase the width of the short side of the lamp body 1, so that the entire lamp can be made into a small or extremely small size. The maximum width of the entire lamp can be made less than or equal to 12mm, which can meet the installation requirements of small-sized mounting grooves on the building installation surface. In addition, during the light-emitting process, after two reflections from the lens 33 and the reflector 4, the light is mixed more fully and evenly, making the light mixing and color mixing effects of the linear lamp better.

[0033] In a preferred embodiment, see Figure 2 、 5 The lampshade 2 has second mounting grooves 23 on both sides, which are respectively plugged into the two sides of the opening 11. This arrangement ensures stable installation of the lampshade 2. The two sides of the lampshade 2 are flush with the two sides of the lamp body 1, that is, the light-emitting surface of the lampshade 2 is consistent with the width of the lamp body 1. After the lamp body 1 is installed in the mounting groove on the building surface, the light-emitting surface of the lampshade 2 fills the entire surface of the mounting groove on the building surface, achieving a better lighting effect.

[0034] In a preferred embodiment, see Figure 1 、 4 A wire groove 14 is provided on the side of the lamp body 1 away from the opening 11. Since the power driver electrically connected to the power board is provided on the outer wall of the lamp body 1, through the above arrangement, the power driver and related wires can be hidden in the wire groove 14 to facilitate the wiring of the linear light.

[0035] In the above, the power driver and wires are not drawn in the drawings.

[0036] It should be noted that both ends of the lamp body 1 are provided with end covers, which are not shown in the accompanying drawings. The end covers are used to seal the lamp body 1 to prevent dust and water.

[0037] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the claims attached to the present invention.
