Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, specifically to a wooden shelf lamp. Background Technology

[0002] Wooden shelf lights, widely used in home cabinets, display shelves, bookshelves, and commercial shelving, primarily provide functional lighting and ambient lighting effects through built-in LED light sources, enhancing the sense of space and user experience. Existing typical structures usually embed LED light strips into an aluminum profile base, covered with a PC (polycarbonate) or PMMA (acrylic) light-transmitting cover to achieve light emission from both the top and bottom, meeting the needs of illuminating items inside the cabinet and supplementing ambient light. However, this type of product exhibits significant limitations in practical use: because the LED light source is mostly fixed in the central cavity of the aluminum profile, the emitted light undergoes multiple reflections and transmissions within the limited space, making it easily absorbed by surrounding materials and resulting in low reflection path efficiency, leading to insufficient brightness and poor uniformity. To improve illuminance, a common approach is to increase LED power or density, but this causes a significant increase in the internal temperature of the lamp. The limited heat dissipation capacity of the aluminum profile leads to accelerated LED chip decay, shortened lifespan, and even affects the safety and stability of the surrounding wooden structure.

[0003] In conclusion, existing technologies cannot simultaneously guarantee light output brightness while also ensuring heat dissipation performance and lamp lifespan. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing wooden shelf lamp solutions cannot simultaneously ensure light output brightness while also taking into account heat dissipation performance and lamp life, and to provide a new type of wooden shelf lamp.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0006] A wooden panel lamp includes a long, narrow lamp holder, a light strip mounted on the lamp holder, and a lampshade connected to the lamp holder. The lamp holder has first mounting portions on both sides along its height. The lampshade includes a reflective portion and light-transmitting portions connected to both sides of the reflective portion along its height, with the light-transmitting portions extending outward from the reflective portion. A second mounting portion connected to the first mounting portions is located at the end of the light-transmitting portion away from the reflective portion. The light strip is mounted on the lamp holder, with its luminous surface facing the reflective portion. A light-guiding protrusion is located on the side of the reflective portion opposite the light strip, and two inclined reflective surfaces are formed on the light-guiding protrusion. The two inclined reflective surfaces extend obliquely from the middle of the side closest to the light strip towards the light-transmitting portion on one side.

[0007] This invention features a light-guiding protrusion on the side of the lampshade's reflective section closest to the light strip. Utilizing two upwardly and downwardly extending reflective surfaces, the light emitted from the light strip is efficiently collected and directionally reflected, guiding it upwards and downwards respectively, and finally emitted evenly through the upper and lower light-transmitting sections. Compared to existing technologies, this invention effectively improves light extraction efficiency and brightness, enhances light uniformity, and thus reduces power consumption, heat generation, and lamp lifespan while achieving the same lighting effect. It also boasts a compact structure and reliable safety.

[0008] Furthermore, the angle α between the tilted reflective surface and the light-transmitting part is between 45° and 75°, and the ratio b of the protrusion thickness d of the light-guiding protrusion to the width of the light-transmitting part is 1:3 to 1:5. This design, with an angle α of 45-75 degrees between the tilted reflective surface and the light-transmitting part, ensures that the light emitted by the LED can be incident on the reflective surface at an optimal angle and efficiently guided to the desired vertical light emission direction. Simultaneously, the ratio of the protrusion thickness d of the light-guiding protrusion to the width b of the light-transmitting part (1:3 to 1:5) precisely controls the relationship between the light "reflection mixing zone" and the "light guiding diffusion zone." This ratio ensures that the light can be fully dispersed and redistributed within a compact space, thereby forming a uniform glow across the entire light-emitting surface and effectively avoiding the optical defects of excessive brightness near the lamp and excessive darkness at the far end.

[0009] Furthermore, the ratio b of the side length of the inclined reflective surface to the width of the light-transmitting part is between 6:5 and 3:2. In this design, the side length of the inclined reflective surface is greater than the width of the light-transmitting part, making the longitudinal height of the reflective surface greater than the lateral width of the light-transmitting area, ensuring complete coverage of the light path. The longer reflection path ensures that the light emitted from the LED, even if the angle is deflected, can still reach the far edge of the light-transmitting part after reflection by the inclined reflective surface, thus effectively avoiding dark areas on the light-transmitting surface.

[0010] Furthermore, the first mounting part is a buckle protruding from the lamp holder towards the lamp cover, and the second mounting part is an elastic buckle protruding towards the lamp holder. The elastic buckle is adapted to the shape of the buckle and is elastically engaged with the buckle.

[0011] Furthermore, the buckle is arranged along the length of the lamp holder, with an "L"-shaped cross-section, forming a groove that opens towards the center between it and the lamp holder body. The elastic buckle is located on the groove. This design ensures that after the lamp holder and lampshade are assembled, the connection between them is flush, and the buckle structure is not exposed.

[0012] Furthermore, the lamp holder has a mounting groove along its length in the middle, and the light strip is disposed in the mounting groove. The lamp holder also has a shielding part protruding towards the lampshade side along its length, and the shielding part is located on the outer side of opposite sides of the mounting groove. The shielding part is flush with the first mounting part in the width direction. In this design, the light emitted by the light strip will illuminate the light-transmitting part and the reflective part, and due to the design of the shielding part, it will not directly illuminate the first mounting part.

[0013] Furthermore, the two tilted reflective surfaces are low-curvature arc surfaces. This design helps to further optimize the uniformity of light output and soften the light. The low-curvature arc surfaces can disperse the concentrated beam of light, forming a softer and more uniform "surface light source" effect, avoiding the user seeing the glaring image of the LED beads.

[0014] Furthermore, the reflective part is made of an opaque, high-reflectivity material, the light-transmitting part is made of a light-transmitting material, and the reflective part and the light-transmitting part are integrally formed.

[0015] Furthermore, the reflective part and the light-transmitting part are manufactured using a two-color injection molding process.

[0016] Furthermore, it also includes a cover, wherein the lamp holder and the lamp cover are joined together to form a hollow structure with openings at both ends, and the cover is provided at the opening and closes the opening.

[0017] Furthermore, the upper end of the lamp holder is provided with a connecting part that protrudes away from the lamp cover, and the connecting part and the lamp holder body form an installation recess.

[0018] Furthermore, the surface of the reflective part on the side away from the light strip is a concave arc surface. Attached Figure Description

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings:

[0027] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "front", "rear", "inner", and "outer" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this utility model and simplifying the description, and does 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. Therefore, it should not be construed as a limitation of this utility model.

[0028] See Figure 1-5 As shown, this utility model discloses a wooden plywood lamp, including a long strip lamp holder 1, a light strip 2 disposed on the lamp holder 1, and a lampshade 3 connected to the lamp holder 1. The lamp holder 1 has first mounting portions 4 on both sides in the height direction. The lampshade 3 includes a reflective portion 5 and light-transmitting portions 6 connected to both sides of the reflective portion 5 in the height direction. The light-transmitting portions 6 extend outward from the reflective portion 5. The end of the light-transmitting portion 6 away from the reflective portion 5 has a second mounting portion 7 connected to the first mounting portion 4. The light strip 2 is disposed on the lamp holder 1, and its light-emitting surface faces the reflective portion 5. The end of the reflective portion 5 facing the light strip 2 has a light-guiding protrusion 8. Two inclined reflective surfaces 9 are formed on the light-guiding protrusion 8. The two inclined reflective surfaces 9 extend obliquely from the middle of the side near the light strip 2 towards the light-transmitting portion 6 on one side.

[0029] Furthermore, the angle α between the inclined reflective surface 9 and the light-transmitting part 6 is between 45° and 75°, and the ratio of the depth of the light-guiding protrusion 8 to the width of the light-transmitting part 6 is 1:3 to 1:5. This design, with the angle α between the inclined reflective surface 9 and the light-transmitting part 6 at 45-75 degrees, ensures that the light emitted by the LED can be incident on the reflective surface at a better angle and efficiently guided to the expected vertical light emission direction. Simultaneously, the ratio of the depth of the light-guiding protrusion 8 to the width of the light-transmitting part 6 (1:3 to 1:5) precisely controls the relationship between the light "reflection mixing zone" and the "light guiding diffusion zone." This ratio ensures that the light can be fully dispersed and redistributed within a compact space, thereby forming a uniform glow across the entire light-emitting surface and effectively avoiding the optical defects of excessive brightness near the lamp and excessive darkness at the far end.

[0030] Furthermore, the ratio of the side length of the inclined reflective surface 9 to the width of the light-transmitting portion 6 is 6:5 to 3:2. In this design, the side length of the inclined reflective surface 9 is greater than the width of the light-transmitting portion 6, making the longitudinal height of the reflective surface greater than the lateral width of the light-transmitting area, ensuring complete coverage of the light path. The longer reflection path ensures that even if the angle of the light emitted from the LED is skewed, its light path can still fully reach the far edge of the light-transmitting portion 6 after reflection by the inclined reflective surface 9, thereby effectively avoiding dark areas on the light-transmitting surface.

[0031] Furthermore, the first mounting part 4 is a buckle protruding from the lamp holder 1 toward the lamp cover 3, and the second mounting part 7 is an elastic buckle protruding toward the lamp holder 1. The elastic buckle is adapted to the shape of the buckle and is elastically engaged with the buckle.

[0032] Furthermore, the buckle is arranged along the length of the lamp holder 1, and its cross-section is "L"-shaped, forming a groove 10 that opens towards the center between the lamp holder 1 and the main body of the lamp holder 1. The elastic buckle is provided on the groove 10. This design ensures that after the lamp holder 1 and the lamp cover 3 are assembled, the connection between the two is flush, and the buckle structure is not exposed.

[0033] Furthermore, the lamp holder 1 has a mounting groove 11 along its length in the middle, and the light strip 2 is disposed in the mounting groove 11. The lamp holder 1 has a blocking part 12 protruding towards the lamp cover 3 along its length, and the blocking part 12 is located on the outer side of opposite sides of the mounting groove 11. The blocking part 12 is flush with the first mounting part 4 in the width direction. In this design, the light emitted by the light strip 2 will illuminate the light-transmitting part 6 and the reflective part 5, and due to the design of the blocking part, it will not directly illuminate the first mounting part 4.

[0034] Furthermore, the two tilted reflective surfaces 9 are low-curvature arc surfaces. This design helps to further optimize the uniformity of light output and soften the light. The low-curvature arc surface can disperse the concentrated light beam, forming a softer and more uniform "surface light source" effect, avoiding the user seeing the glaring image of the LED beads.

[0035] Furthermore, the reflective part 5 is made of an opaque, high-reflectivity material, and the light-transmitting part 6 is made of a light-transmitting material, and the reflective part 5 and the light-transmitting part 6 are integrally formed.

[0036] Furthermore, the reflective part 5 and the light-transmitting part 6 are manufactured using a two-color injection molding process.

[0037] Furthermore, it also includes a cover 13, wherein the lamp holder 1 and the lamp shade 3 are joined together to form a hollow structure with openings at both ends, and the cover 13 is provided at the opening and closes the opening.

[0038] Furthermore, the upper end of the lamp holder 1 is provided with a rearwardly protruding connecting part 14, and the connecting part 14 and the lamp holder 1 body form an installation recess 15.

[0039] Furthermore, the surface of the reflective part 5 on the side away from the light strip 2 is a concave arc surface.

[0040] This invention features a light-guiding protrusion 8 on the side of the lampshade 3's reflective part 5 near the lamp strip 2. Utilizing two upwardly and downwardly extending reflective surfaces, the light emitted from the lamp strip 2 is efficiently collected and directionally reflected, guiding it to the upper rear and lower rear respectively, and finally uniformly emitted through the upper and lower light-transmitting parts 6. Compared with existing technologies, this invention effectively improves light extraction efficiency and brightness, enhances light uniformity, and thus reduces power consumption, heat generation, and lamp life while achieving the same lighting effect. It also features a compact structure and high reliability.
