Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a top-and-bottom luminaire. Background Technology

[0002] Most mainstream lighting fixtures on the market, such as pendant lights, table lamps, ceiling lights, wall lamps, and floor lamps, are designed with a single-direction light emission structure (i.e., mostly downward-facing). This structure can only achieve basic localized accent lighting and cannot emit soft ambient light upwards to create a warm and comfortable spatial atmosphere. For example, traditional pendant lights can only output downward accent lighting for dining tables and desks. If users need to create a relaxing atmosphere in the same space, they need to purchase additional ambient lights, which not only increases usage costs but also occupies more installation or placement space. Therefore, the core defect of existing technology is that a single lamp type cannot simultaneously achieve upward ambient lighting and downward accent lighting. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a lamp that emits light from both the top and bottom, so that the same lamp type can simultaneously output upward ambient light and downward accent lighting, thereby meeting diverse lighting needs.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A top-and-bottom light fixture includes an upper light-emitting module with the light emission direction facing upward and a lower light-emitting module with the light emission direction facing downward. The upper light-emitting module includes a first light source component, a colored diffuser, and a transparent outer cover. The outer cover is fitted over the outside of the diffuser, and the first light source component is located inside the diffuser. The lower light-emitting module includes a second light source component and a light control component. The second light source component is mounted on the diffuser and located between the diffuser and the light control component.

[0005] Furthermore, the diffuser is amber in color.

[0006] Furthermore, the diffusion surface of the diffusion cover is recessed towards the first light source assembly.

[0007] Furthermore, the first light source assembly includes a plurality of light-emitting plates arranged at equal angles around the central axis of the diffuser.

[0008] Furthermore, the light-emitting plate includes a first lens and LED beads, with the first lens disposed at the light-emitting end of the LED beads.

[0009] Furthermore, the number of light-emitting panels is eight.

[0010] Furthermore, the light control component is a second lens, the second light source component is located between the diffuser and the second lens, and the light-emitting end of the second light source component faces the second lens.

[0011] Furthermore, the second lens is a TIR lens, and the light output angle of the TIR lens is 0°-90°.

[0012] Furthermore, the light control component is a light guide plate, and the second light source component is located between the diffuser and the light guide plate, with the light-emitting end of the second light source component facing the light guide plate.

[0013] Furthermore, the upper light-emitting module also includes a support member, which is disposed inside the diffuser cover, and the first light source assembly is disposed on the support member.

[0014] The beneficial effects of this utility model are as follows: This solution breaks through the structural limitations of traditional lamps that emit light in only one direction by setting an upward-facing upper light-emitting module and a downward-facing lower light-emitting module. This allows a single lamp type to simultaneously achieve two lighting functions: the upper light-emitting module, through a double-layer structure consisting of a colored diffuser and a transparent outer cover, along with its internal first light source component, outputs soft ambient light upwards to meet the needs of creating spatial atmosphere. The lower light-emitting module, by setting a second light source component and a light control component outside the double-layer structure, outputs focused lighting downwards, suitable for localized lighting scenarios such as reading and working. The lamp designed in this solution does not require the purchase of two separate lamps, reducing user costs and saving installation or placement space. Attached Figure Description

[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figure 1 and Figure 2 A light fixture with upward and downward light emission, comprising an upper light-emitting module 1 with the light emission direction facing upward and a lower light-emitting module 2 with the light emission direction facing downward; The upper light-emitting module 1 includes a first light source assembly 12, a colored diffuser 11, and a transparent outer cover 14. The outer cover 14 is fitted outside the diffuser 11, and the first light source assembly 12 is located inside the diffuser 11. The lower light-emitting module 2 includes a second light source component 21 and a light control component 22. The second light source component 21 is installed outside the diffuser 11 and located between the diffuser 11 and the light control component 22.

[0018] As can be seen from the above description, the beneficial effects of this utility model are as follows: This solution breaks through the structural limitations of traditional lamps that emit light in only one direction by setting up an upper light-emitting module 1 that emits light upwards and a lower light-emitting module 2 that emits light downwards. This allows a single lamp type to simultaneously achieve two lighting functions: the upper light-emitting module 1, through a double-layer structure consisting of a colored diffuser 11 and a transparent outer cover 14, and its internal first light source component 12, outputs soft ambient light upwards to meet the needs of creating spatial atmosphere. The lower light-emitting module 2, through setting a second light source component 21 and a light control component 22 outside the double-layer structure, outputs focused lighting downwards, suitable for local lighting scenarios such as reading and working. The lamp designed in this solution does not require the purchase of two additional lamps, which reduces user costs and saves installation or placement space.

[0019] For further details, please refer to Figure 2 The diffuser shroud 11 is amber in color.

[0020] As can be seen from the above description, the amber-colored diffuser 11 can soften the light from the first light source component 12, preventing the light from shining directly into the eyes and making the ambient light more suitable for creating a warm and soothing spatial environment.

[0021] For further details, please refer to Figure 2 The diffusion surface of the diffuser shroud 11 is recessed towards the first light source assembly 12.

[0022] As can be seen from the above description, by limiting the diffusion surface of the diffuser 11 to be recessed into the first light source component 12, the diffuser 11 with the concave diffusion surface can increase the contact area with the light from the first light source component 12, so that the light is softened more fully, avoids the "spot" problem caused by local light concentration, and improves the uniformity of ambient light.

[0023] For further details, please refer to Figure 2 and Figure 3 The first light source assembly 12 includes a plurality of light-emitting plates 121 arranged at equal angles around the central axis of the diffuser 11.

[0024] As can be seen from the above description, the first light source component 12 adopts multiple light-emitting plates 121 arranged at equal angles around the central axis of the diffuser 11, which can ensure that the light of the first light source component 12 is evenly distributed in a ring within the diffuser 11, avoiding the local ambient light from being too bright or too dark due to the light source being concentrated in a certain area, ensuring that the ambient light is evenly covered in the space, and improving the user experience.

[0025] For further details, please refer to Figure 3 The light-emitting plate 121 includes a first lens 1211 and an LED bead 1212, wherein the first lens 1211 is disposed at the light-emitting end of the LED bead 1212.

[0026] As can be seen from the above description, the light-emitting plate 121 includes a first lens 1211 and a light source. The first lens 1211 can initially guide and regulate the light emitted by the light source, and converge the divergent light in a designated direction (towards the amber diffuser 11), reducing the loss caused by irregular scattering of light, so that the light can act on the amber diffuser 11 more efficiently, avoiding insufficient ambient light brightness due to light loss. At the same time, the first lens 1211 can protect the light source from dust contamination, extend the service life of the light source, and ensure long-term stable output of ambient light.

[0027] For further details, please refer to Figure 2 and Figure 3 The number of light-emitting panels 121 is eight.

[0028] As described above, setting the number of light-emitting panels 121 to eight and arranging them in a ring at equal angles, with the included angle between adjacent light-emitting panels 121 being 45°, can further optimize the distribution density of light within the double-layer cover. This makes it easier for the light to form a "bright and dark interlaced diamond-shaped light-emitting pattern" after passing through the amber-colored diffuser 11 and the outer cover 14, enhancing the visual layering and design of the ambient light. This distinguishes it from the single light effect of traditional ambient lights, improving the competitiveness of the lighting products. At the same time, the configuration of eight light-emitting panels 121 can achieve a balance between "brightness requirements" and "energy consumption control," satisfying the brightness requirements of the ambient light while avoiding the problem of excessive energy consumption caused by too many light sources.

[0029] For further details, please refer to Figure 2 The light control component 22 is a second lens, and the second light source component 21 is located between the diffuser 11 and the second lens, with the light-emitting end of the second light source component 21 facing the second lens.

[0030] As described above, the light control component 22 uses a second lens, and the second light source component 21 is located between the diffuser 11 and the second lens. The light-emitting end of the second light source component 21 faces the second lens. The second lens can converge or directionally guide the light from the second light source component 21, so that the focused lighting light can accurately act on the target area below (such as a specific reading area on a desk or the center area of ​​a dining table), avoiding energy waste caused by light dispersion. At the same time, directional lighting can reduce light interference to the surrounding environment (such as not disturbing others' rest when reading at night), adapting to scenarios that require precise lighting and improving the practicality of focused lighting.

[0031] Furthermore, the second lens is a TIR lens, and the light output angle of the TIR lens is 0°-90°.

[0032] As can be seen from the above description, the second lens is a TIR lens with a light emission angle of 0°-90°. TIR lenses have the characteristic of high light focusing efficiency and can be flexibly adapted to different lighting ranges according to actual scenarios. At the same time, the structural design of TIR lenses can reduce light loss and ensure the brightness and efficiency of key lighting light, which meets the functional requirements of "downward emission to form key lighting light".

[0033] For further details, please refer to Figure 2 The light control component 22 is a light guide plate, and the second light source component 21 is located between the diffuser 11 and the light guide plate, with the light-emitting end of the second light source component 21 facing the light guide plate.

[0034] As can be seen from the above description, the light control component 22 adopts a light guide plate, which can uniformly process the light from the second light source component 21, so that the key lighting light is evenly distributed in a planar shape, avoiding local light spots that are too bright or too dark, and is suitable for scenarios such as desktop work areas and bedroom floors that require large-area uniform key lighting.

[0035] For further details, please refer to Figure 2 The upper light-emitting module 1 also includes a support member 13, which is disposed inside the diffuser hood 11, and the first light source assembly 12 is disposed on the support member 13.

[0036] As can be seen from the above description, the upper light-emitting module 1 is equipped with a support member 13, which is located inside the diffuser 11. The first light source assembly 12 is located on the support member 13. The support member 13 provides a stable mounting carrier for the diffuser 11 and the first light source assembly 12, ensuring that the relative positions of each component are fixed and avoiding problems such as "light shift" and "uneven ambient light" caused by component displacement during the transportation or use of the lamp. At the same time, the support member 13 can also serve as a carrier for hiding wires and installing the drive assembly 6 (such as embedding the drive assembly 6 inside the support member 13), making the appearance of the lamp simpler and reducing the safety hazards and visual clutter caused by exposed external wires.

[0037] Please refer to Figures 1 to 9 As shown, Embodiment 1 of this utility model is as follows: Please refer to Figure 1 and Figure 2 A light fixture with upward and downward light emission, comprising an upper light-emitting module 1 with the light emission direction facing upward and a lower light-emitting module 2 with the light emission direction facing downward; The upper light-emitting module 1 includes a first light source assembly 12, a colored diffuser 11, and a transparent outer cover 14. The outer cover 14 is fitted outside the diffuser 11, and the first light source assembly 12 is located inside the diffuser 11. The lower light-emitting module 2 includes a second light source component 21 and a light control component 22. The second light source component 21 is installed outside the diffuser 11 and located between the diffuser 11 and the light control component 22.

[0038] The upper and lower lighting fixtures in this design can be chandeliers (i.e.,...) Figure 7 ), desktop lamp (i.e. Figure 8 ), floor lamp (i.e.) Figure 9 )wait.

[0039] In this embodiment, the second light source component 21 is a COB light source, which stands for Chip-on-Board. It is a high-power integrated surface light source technology that forms a dense array by directly mounting multiple LED chips on a metal or ceramic substrate, achieving high luminous efficiency, uniform light emission, and excellent heat dissipation performance. It is widely used in commercial lighting, stage lighting, and other fields.

[0040] Please refer to Figure 2 The diffuser shroud 11 is amber in color.

[0041] Please refer to Figure 2The diffusion surface of the diffuser shroud 11 is recessed towards the first light source assembly 12.

[0042] Please refer to Figure 2 and Figure 3 The first light source assembly 12 includes a plurality of light-emitting plates 121 arranged at equal angles around the central axis of the diffuser 11.

[0043] Please refer to Figure 3 The light-emitting plate 121 includes a first lens 1211 and an LED bead 1212 (in this embodiment, the light source is a monochromatic 2000K LED bead), and the first lens 1211 is disposed at the light-emitting end of the LED bead 1212.

The light output angle of the TIR lens is 0°-90°, and the common angle designs are 8°, 10°, 15°, 24°, 36°, 60° and 90°.

[0047] Please refer to Figure 2 The light control component 22 is a light guide plate, and the second light source component 21 is located between the diffuser 11 and the light guide plate, with the light-emitting end of the second light source component 21 facing the light guide plate.

[0048] In this embodiment, the light control component 22 may also consist of a diffuser and a transparent outer cover.

[0049] Please refer to Figure 2 The upper light-emitting module 1 also includes a support member 13, which is disposed inside the diffuser hood 11, and the first light source assembly 12 is disposed on the support member 13.

[0050] Please refer to Figure 2 A heat dissipation aluminum plate 3 is provided between the lower light-emitting module 2 and the diffuser cover 11, and the heat dissipation aluminum plate 3 is connected to the lower light-emitting module 2 and the diffuser cover 11 respectively.

[0051] Please refer to Figure 2 The lower light-emitting module 2 also includes a bracket 23, and the light control component 22 is mounted on the heat dissipation aluminum plate 3 through the bracket 23.

[0052] Please refer to Figure 3 It also includes a drive component 6, which is disposed inside the support member 13 and is electrically connected to the first light source component 12 and the second light source component 21 respectively.

[0053] Please refer to Figures 4 to 6 The support member 13 includes a base plate 131. The side of the base plate 131 near the second light source assembly 21 protrudes in a direction away from the second light source assembly 21 to form an octagonal boss 132. The eight light-emitting plates 121 are respectively disposed on the eight side surfaces of the boss 132. The boss 132 is provided with a mounting cylinder 133. The driving assembly 6 is installed in the inner cavity of the mounting cylinder 133. One end of the mounting cylinder 133 extends into the inside of the boss 132, and the second light source assembly 21 and the bracket 23 are installed on one end of the mounting cylinder 133.

[0054] Please refer to Figure 2 It also includes an upper decorative cover 4 (designed when the lamp is a pendant lamp, not required for desktop lamps and floor lamps) and a lower decorative cover 5. The upper decorative cover 4 is installed on the top of the outer cover 14, the lower decorative cover 5 is installed on the bottom of the diffuser cover 11, and the lower light-emitting module 2 is located inside the lower decorative cover 5.

[0055] The upper decorative cover 4 is an injection-molded structural component, designed with screw positioning / fixing posts and hanging wire slots.

[0056] The outer cover 14 is designed with slots and positioning holes, which can be fully matched and assembled with the upper decorative cover 4 and the lower decorative cover 5.

[0057] The lower decorative cover 5 has lens buckles, slots and positioning punches, and is assembled with light control components 22, support members 13 and outer cover 14.

[0058] The light control component 22 (e.g., the second lens) is pressed and assembled with the lower decorative cover 5 by a snap-fit, and is also matched and assembled with the light source fixing component (used to press and fix the light source, lock it on the support component 13, and match the second lens for positioning) through the positioning piece.

[0059] The working principle of the above-mentioned top and bottom luminaires is as follows: Upper light-emitting module 1 (upward ambient light output): The driving component 6 supplies power to the light source of the first light source component 12. After the light source emits light, the light is refracted by the octagonal lens (i.e., composed of eight first lenses 1211) and shines outward onto the amber-colored diffuser 11. Because the diffuser 11 has an inwardly concave arc surface, the contact area between the light and the diffuser 11 is increased, and the light is fully softened by the amber-colored material. Then, it diffuses upward and into the surrounding space through the outer cover 14 with an outwardly convex arc surface, forming a warm-colored diffused ambient light to create a spatial atmosphere.

[0060] Lower light-emitting module 2 (downward focused illumination output): The driving component 6 simultaneously powers the COB light source of the second light source component 21. After the COB light source emits light, the light is directly incident on the light control component 22 (such as a TIR lens / light guide plate / "milky white diffuser combined with a transparent outer cover", etc.). If the light control component 22 is a TIR lens, the light is focused by the lens to form a highly directional spotlight that accurately illuminates the target area below (such as a dining table or desk). If the light control component 22 is a light guide plate, the light is uniformly processed inside the light guide plate and then emitted from the light-emitting surface to form a uniform focused illumination light covering a large area. If the light control component 22 is "a milky white diffuser combined with a transparent outer cover (i.e., the transparent outer cover is placed on the outside of the milky white diffuser, and the inside of the milky white diffuser is a circle of downward-emitting LED light sources and a single small lens, which is locked onto the support 13. The milky white diffuser forms soft light, and combined with the transparent outer cover, it forms a bright light output effect)," the light is softened by the diffuser and protected by the transparent outer cover, forming a soft, planar focused illumination light.

[0061] Collaborative working logic: Through the control function of the drive component 6, three modes can be switched: "ambient light only", "accent lighting only", and "ambient light and accent lighting". When relaxing, only the upper light-emitting module 1 is turned on to create an atmosphere. When reading, only the lower light-emitting module 2 is turned on to meet the accent lighting. When having a party, both are turned on at the same time to take into account both atmosphere and lighting. This allows the same lamp type to output upward ambient light and downward accent lighting at the same time, meeting diverse lighting needs.

[0062] In summary, the present invention provides a top-and-bottom luminaire that, by setting an upward-facing upper luminaire module and a downward-facing lower luminaire module, breaks through the structural limitation of traditional luminaires that emit light in only one direction. This allows a single luminaire to simultaneously achieve two lighting functions: the upper luminaire module, through a double-layer structure consisting of a colored diffuser and a transparent outer cover, and its internal first light source component, outputs soft ambient light upwards to meet the needs of creating spatial atmosphere; the lower luminaire module, by setting a second light source component and a light control component outside the double-layer structure, outputs focused lighting downwards, suitable for localized lighting scenarios such as reading and working. The luminaire designed in this solution eliminates the need to purchase two separate luminaires, reducing user costs and saving installation or placement space.

[0063] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
