Description

Technical Field

[0001] This utility model relates to the field of lighting product technology, and in particular discloses a double-slot double-light-emitting lamp housing. Background Technology

[0002] In recent years, with the growing popularity of low-carbon economy and energy-saving and environmental protection concepts, and with the strong promotion of the national and local governments, the LED lighting industry has flourished. As a new generation of green light source, LEDs (light-emitting diodes) have advantages such as low energy consumption, long lifespan, small size, and fast response, and have been widely used in home lighting, commercial lighting, decorative lighting, display backlighting, and urban nightscape projects.

[0003] Most existing lighting fixtures use a single-slot structure, allowing only a single light strip to be installed, resulting in a limited lighting direction and failing to meet the needs of multi-angle lighting. While some double-slot fixtures can accommodate two light strips, the two slots are often located on the same wall or in adjacent areas, easily leading to uneven light mixing, severe glare, and inconvenient installation. Furthermore, the optical components of existing fixtures are relatively simple, typically only equipped with a diffuser plate, which cannot effectively control the direction and uniformity of light diffusion, resulting in low light energy utilization. In addition, existing fixtures are mostly installed using screw fixing or gluing methods, making construction complex and maintenance inconvenient.

[0004] Therefore, there is an urgent need for a dual-lamp slot, dual-light-emission lamp housing with a reasonable structure, convenient installation, and stronger controllability of light efficiency to solve the shortcomings of existing technologies. Utility Model Content

[0005] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a double-slot double-emitting lamp housing with reasonable structure, convenient installation and stronger controllability of light effect.

[0006] To achieve the above objectives, this utility model provides a dual-slot, dual-emission lamp housing, comprising a housing and receiving slots disposed on the housing. The receiving slots are used to accommodate external light strips. Multiple sets of receiving slots are provided, and these sets are not interconnected. Each set includes a first receiving slot and a second receiving slot, located on adjacent first and second walls of the housing, respectively. Both the first and second walls are planar walls, and the included angle between them is 0-180°. The opening area of ​​at least one receiving slot is less than half the area of ​​the wall it occupies. This utility model, through its dual-slot design, enables the installation of two light strips within a single housing. The illumination range and light emission uniformity can be adjusted according to the slot opening area ratio, resulting in richer lighting effects. Unlike traditional single-slot lamp housings that only emit light in one direction, this design can simultaneously accommodate two light strips, achieving bidirectional light emission and improving lighting utilization and decorative appeal.

[0007] Specifically, the opening area of ​​the first receiving groove is greater than half the area of ​​the first wall of the shell, and the opening area of ​​the second receiving groove is less than half the area of ​​the second wall of the shell.

[0008] Specifically, the housing is provided with a first stop portion, and a first receiving groove and a second receiving groove are respectively located on both sides of the first stop portion. The first receiving groove is used to receive an external first light strip, and the second receiving groove is used to receive an external second light strip.

[0009] Specifically, the first stop portion includes a first plate, a second plate bent from the first plate, and an arc segment. The arc segment cooperates with the second wall of the housing to clamp the external first light guide. The first light guide and the first stop portion block the second light strip. The light emitted by the second light strip is diffused to the outside of the housing through the first light guide.

[0010] Specifically, the first light guide includes a first diffuser plate, both ends of which are provided with stepped flanges. The arc-shaped section and the second wall of the housing are provided with first slots that are adapted to the stepped flanges. The stepped flanges extend into the first slots so that the outer end face of the first diffuser plate is smoothly connected to the outer end face of the second wall of the housing.

[0011] Specifically, the opening area of ​​the second receiving groove is smaller than that of the first receiving groove.

[0012] Specifically, the housing is provided with a second stop portion, which cooperates with the first wall of the housing to clamp the external second light guide. A second slot is formed between the second stop portion and the first wall or the third wall of the housing, and the second slot is used to limit the displacement of the second light strip.

[0013] Specifically, the first stop and / or the second stop are provided with mounting holes, the mounting holes are provided with threads, and the external plug is connected to the housing via screws and mounting holes.

[0014] Specifically, the second light guide includes a second diffuser plate, a light guide plate, and reflective paper arranged in sequence. The light guide plate blocks the external first light strip. The light emitted by the first light strip is diffused to the outside of the housing through the light guide plate and the second diffuser plate. The reflective paper is used to reflect the light and allow it to pass through the light guide plate and the second diffuser plate before being emitted.

[0015] Specifically, the housing is an integrally formed aluminum profile; a magnetic unit is provided in the accommodating groove, and the housing is adsorbed onto an external magnetically conductive component via the magnetic unit.

[0016] The beneficial effects of this utility model are as follows: Through the design of the double accommodating slot, this utility model can realize the installation of two light strips in an integrated housing, and adjust the illumination range and light output uniformity according to the area ratio of the slot, so as to make the lighting effect richer. Unlike the traditional single-slot lamp housing, which can only emit light in one direction, this design can accommodate two light strips at the same time, realize bidirectional light output, and improve the lighting utilization rate and decoration.

[0017] The combination of the blocking part and the light guide controls the light effect and reduces glare. The stepped flange and slot structure makes the diffuser plate installation reliable and beautiful. The multi-layer light guide combination improves the uniformity and brightness of the light effect. The one-piece aluminum profile structure has good heat dissipation and long service life. The magnetic fixing method makes installation simple and disassembly convenient, making it particularly suitable for metal substrate lighting scenarios. Attached Figure Description

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] Please see Figures 1 to 6 As shown, this utility model discloses a double-slot, double-emitting lamp housing, comprising a housing 1 and a receiving slot disposed on the housing 1, the receiving slot being used to accommodate external lamp strips; the receiving slot is provided in multiple sets, the multiple sets of receiving slots are not interconnected, the multiple sets of receiving slots include a first receiving slot 2 and a second receiving slot 3, the first receiving slot 2 and the second receiving slot 3 are respectively located on a first wall 4 and a second wall 5 adjacent to the housing 1, the first wall 4 and the second wall 5 are both planar walls, the included angle between the first wall 4 and the second wall 5 is 0-180°, and the slot opening area of ​​at least one receiving slot is less than half the area of ​​the wall on which it is located.

[0028] The opening area of ​​the first accommodating slot 2 is greater than half the area of ​​the first wall 4 of the housing 1, and the opening area of ​​the second accommodating slot 3 is less than half the area of ​​the second wall 5 of the housing 1. This invention, through its double-accommodating slot design, enables the installation of two light strips within the integrated housing 1. Furthermore, it allows for adjustment of the illumination range and light uniformity based on the slot area ratio, resulting in richer lighting effects. Unlike traditional single-slot lamp housings that only emit light in one direction, this design can simultaneously accommodate two light strips, achieving bidirectional light emission and improving lighting utilization and decorative appeal.

[0029] Specifically, the first light strip 7 is a regular LED light strip, and the second light strip 8 is a color-changing LED bead with built-in ICs. Each built-in IC can be controlled by a voice control program. Each color-changing LED bead can independently change to different colors to display different lighting effects. When all the LED beads change colors together, the light color of the light panel is rich, colorful, and infinitely varied. The light from the first light outlet provides illumination, while the light from the second light outlet is rich, colorful, softer, and provides more light and shadow effects.

[0030] The housing 1 is provided with a first stop portion 6, and a first receiving groove 2 and a second receiving groove 3 are respectively located on both sides of the first stop portion 6. The first receiving groove 2 is used to receive the external first light strip 7, and the second receiving groove 3 is used to receive the external second light strip 8. The first stop portion 6 separates the two sets of light strips, so that the light does not mix directly, thereby maintaining the independence of the light effect. Compared with the simple slotting of the existing lamp housing, this solution effectively isolates the light source through the stop portion, avoids glare, and improves the light effect control capability.

[0031] The first blocking part 6 includes a first plate 9, a second plate 10 bent from the first plate 9, and an arc-shaped segment 11. The arc-shaped segment 11 cooperates with the second wall 5 of the housing 1 to clamp the external first light guide 12. The first light guide 12 and the first blocking part 6 block the second light strip 8. The light emitted by the second light strip 8 is diffused to the outside of the housing 1 through the first light guide 12. This achieves independent light guiding and diffusion for different light strips, making the overall lighting effect softer and the zoning more distinct. Unlike conventional direct-emission light strips, this structure achieves zoned light guidance through the cooperation of the blocking part and the light guide, improving the precision of optical control.

[0032] The first light guide 12 includes a first diffuser plate 13, with stepped flanges 14 at both ends. The arc-shaped segment 11 and the second wall 5 of the housing 1 are each provided with a first slot 15 that matches the stepped flanges 14. The stepped flanges 14 extend into the first slots 15, ensuring a smooth connection between the outer end face of the first diffuser plate 13 and the outer end face of the second wall 5 of the housing 1. This slot-type installation ensures a stable and flat diffuser plate installation, avoiding unevenness on the lamp housing surface and improving dustproof performance. Compared to traditional screw or glue fixing methods, this solution uses stepped flanges 14 in conjunction with slots, making installation simpler, disassembly easier, and providing better structural reliability.

[0033] The opening area of ​​the second receiving slot 3 is smaller than that of the first receiving slot 2. By designing different opening areas, the first receiving slot 2 emits a large amount of light, while the second receiving slot 3 emits a relatively soft light, thus creating a primary and secondary light source effect. Unlike the traditional equal-area slot design, this solution controls the light intensity through differentiated slots, enhancing the sense of layering and practicality of the lamp.

[0034] The housing 1 is provided with a second stop 16, which cooperates with the first wall 4 of the housing 1 to clamp the external second light guide 17. A second slot is formed between the second stop 16 and the first wall 4 or the third wall 18 of the housing 1. The second slot is used to limit the displacement of the second light strip 8. By limiting the position of the slot, the stability of the second light strip 8 is ensured, and displacement caused by vibration or external force is avoided, which would affect the lighting effect. Traditional light strips are prone to displacement due to lack of positioning. This structure improves the installation stability and reliability through the cooperation of the stop and the slot.

[0035] The first stop portion 6 and / or the second stop portion 16 are provided with mounting holes 19, and the mounting holes 19 are threaded. The external plug is connected to the housing 1 via screws and mounting holes 19. The mounting holes 19 provide a standardized fixing method, which facilitates the installation of external accessories or end caps and improves the expandability and maintainability of the lamp housing.

[0036] The second light guide 17 includes a second diffuser plate 20, a light guide plate 21, and a reflective paper 22 arranged sequentially. The light guide plate 21 blocks the external light strip, and the light emitted by the light strip is diffused to the outside of the housing 1 through the light guide plate 21 and the second diffuser plate 20. The reflective paper 22 is used to reflect the light and allow it to pass through the light guide plate 21 and the second diffuser plate 20 before being emitted. The combination of multiple optical elements can improve the uniformity and brightness of the emitted light, while avoiding glare caused by direct light source. Unlike the traditional single-layer diffuser plate, this solution adopts a composite structure of reflective paper 22 + light guide plate 21 + diffuser plate, which improves light energy utilization and reduces energy consumption.

[0037] The housing 1 is a one-piece molded aluminum profile. The one-piece molded aluminum material has high strength and good heat dissipation performance, ensuring the long-term stable operation of the light strip. At the same time, the manufacturing process is simple. Unlike plastic shells or spliced ​​metal parts, this solution uses an aluminum profile for integral extrusion molding, which makes the structure more robust and significantly improves heat dissipation and service life.

[0038] The receiving groove is equipped with a magnetic unit 23, and the housing 1 is attracted to the external magnetic conductive component via the magnetic unit 23. Magnetic installation simplifies the construction process, eliminating the need for additional screws or clips, saving labor and installation time. Compared with traditional mechanical fixing, this solution utilizes magnetic attraction to improve installation flexibility and maintenance convenience, and is especially suitable for lighting scenarios with metal substrates.

[0039] Specifically, the magnet unit 23 includes a magnet and a shielding cover surrounding the magnet. The shielding cover is an integral structure and has a blind slot for accommodating the magnet. The opening of the blind slot exposes the end face of the permanent magnet unit 23. The magnet and the shielding cover cooperate to form a unilateral magnetic field. This unilateral magnetic field design avoids magnetic interference from the lamp housing to the back components while enhancing the attraction force on the mounting surface. Compared with ordinary bare magnet installation, this solution achieves magnetic field orientation control through the shielding cover and blind slot structure, improving the stability and safety of the magnetic installation of the lamp.

[0040] Specifically, the shielding cover is made of a magnetically conductive material. This material guides the distribution of magnetic field lines, preventing electromagnetic interference from the magnetic field on the LED strip circuit or control components, while also enhancing the attraction between the magnet unit 23 and external ferrous materials.

[0041] Specifically, the magnet is a neodymium iron boron magnet. By utilizing neodymium iron boron rare-earth permanent magnet material, a small-volume, high-force magnet design is achieved. Without increasing the size of the housing, the lamp housing can be stably attached to external ferrous materials, improving installation convenience.

[0042] Specifically, the magnet is a Helbeck array. The Helbeck array uses a special arrangement to enhance magnetic field lines on one side while almost canceling them out on the other, thus creating a strong unilateral magnetic field. This not only ensures the lamp housing's firm adhesion to external ferrous materials but also reduces the magnetic field strength inside the housing 1, preventing interference with the normal operation of the lamp strip circuit and control module.

[0043] In the first embodiment, when installing the lamp housing, the specifications and power of the required light strips are confirmed, a first light strip 7 and a second light strip 8 are prepared, and corresponding light guides are prepared. The first light strip 7 is embedded into the first receiving groove 2, and its position is stabilized by the groove and the first stop 6. The second light strip 8 is embedded into the second receiving groove 3 and snapped into the second slot formed by the second stop 16 and the wall to prevent displacement. The stepped flange 14 of the first diffuser plate 13 is inserted into the first slot 15 to make it smoothly connect with the outer surface of the housing 1. The reflective paper 22, the light guide plate 21, and the first light strip 8 are placed in the second receiving groove 3 in sequence. Two diffuser plates 20 form a second light guide 17, and the second stop part 16 cooperates with the first wall body 4 to clamp one end of the external second light guide 17. The first stop part 6 is provided with a third slot. The two ends of the second light guide 17 extend into the second slot and the third slot respectively for fixation. After power is turned on, the first light strip 7 in the first receiving slot 2 serves as the main light source to form a wide-area illumination. The second light strip 8 in the second receiving slot 3 softens the light through the light guide plate 21 and the second diffuser plate 20 to achieve auxiliary lighting or ambient lighting effects. The controller can realize independent control of the two light strips, adjust the brightness or combine them for lighting.

[0044] In the second embodiment, compared with the second embodiment, the arc segment 11 is provided with a first slot 15 that is adapted to the stepped flange 14, a first gap is provided between the first light strip 7 and the second wall 5 of the housing 1, one end of the first diffuser plate 13 extends into the first slot 15, the other end of the first diffuser plate 13 extends into the first gap, and a stop block 24 is provided at one end of the first diffuser plate 13 near the first light strip 7, and the stop block 24 cooperates with the housing 1 to clamp the first light strip 7.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
