Description

Technical Field

[0001] The utility model relates to the field of lighting, in particular to a lamp. Background Art

[0002] In the prior art, sky lights are widely used in various commercial and home lighting occasions as a kind of lamps that simulate the natural sky lighting effect. However, there is a common technical problem in the design and use of sky lights, that is, the luminous diameter of the surface light is often smaller than the luminous diameter of the side wall window shadow, resulting in the appearance of visual dark areas.

[0003] Specifically, traditional sky light designs often focus on simulating the visual effects of the sky and white clouds, but in the process of implementation, it is difficult to achieve a perfect fusion of surface light and side window shadow light. The problem of uneven surface light causes uneven distribution of light intensity in the sky part when the lamp is emitting light, resulting in different brightness and darkness, which reduces the overall visual experience.

[0004] In order to solve these problems, the existing technology usually adopts the method of blocking the connection between the surface light and the side wall light. Although this method can improve the connection effect between the surface light and the side wall window shadow light to a certain extent, it cannot fundamentally solve the problem of uneven surface light and light and dark difference.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0033] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0034] See also Figure 1-Figure 8 As shown, a lamp 100 of a preferred embodiment of the utility model includes a shell 1, a first light-emitting module 2 and a second light-emitting module 3 arranged in the shell 1, the first light-emitting module 2 is configured to form a sky-like surface light-emitting effect, and the second light-emitting module 3 is configured to form a side light-emitting effect of a window shadow, and the side light-emitting mode surrounds the surface light-emitting mode to simulate the illumination effect of sunlight.

[0035] The housing 1 includes a top wall 11 and a frame 12, wherein the frame 12 is connected to the top wall 11 and extends in a direction away from the top wall 11. The top wall 11 is used to be fixedly connected to an installation base (e.g., a ceiling, etc.). A power supply assembly is provided on the top wall 11, and the power supply assembly is arranged on a side of the top wall 11 facing the installation base, and the power supply assembly is electrically connected to the first light-emitting module 2 and the second light-emitting module 3 respectively, and supplies power to the first light-emitting module 2 and the second light-emitting module 3.

[0036] Specifically, the first light-emitting module 2 includes a first light-emitting component 21 and a first light-emitting surface 22. The first light-emitting surface 22 is the side of the surface light-emitting component 23 away from the top wall 11. The light emitted by the first light-emitting component 21 passes through the first light-emitting surface 22 and is emitted in a direction away from the top wall 11. The light can be evenly projected downward to provide main lighting for the space. Through the direct-down light-emitting method, the overall uniform light emission of the surface can be achieved without visual dark areas.

[0037] The second light-emitting module 3 includes a second light-emitting component 31 and a second light-emitting surface 32. The second light-emitting surface 32 is arranged on the inner side of the frame 12, and the second light-emitting surface 32 is arranged below the first light-emitting surface 22 and extends in a direction away from the first light-emitting surface 22. The light emitted by the second light-emitting component 31 passes through the second light-emitting surface 32 and is emitted in a direction away from the frame 12.

[0038] Among them, the first light emitting surface 22 has a first projection range on the top wall 11, and the second light emitting surface 32 has a second projection range on the top wall 11, and the second projection range completely falls within the first projection range. Such a configuration makes the light-emitting diameter of the first light-emitting module 2 greater than or equal to the light-emitting diameter of the second light-emitting module 3, ensuring that when the lamp 100 emits light, the surface light source of the first light-emitting module 2 and the side window shadow light source of the second light-emitting module 3 can be integrated with each other, realizing the natural transition of light and forming a continuous and harmonious lighting effect. The close combination of surface light and side window shadow, the light emitted by the sky lamp and the light emitted by the side wall window shadow can be intertwined with each other, forming a seamless lighting effect, avoiding the occurrence of lighting blind spots or dark spots, providing users with a more comfortable visual experience, and also helping to create a warm and harmonious lighting atmosphere. In other words, no matter from which direction the human eye observes the sky lamp, the surface light is always closely integrated with the side wall window shadow, coordinated, and there is no shadow.

[0039] Furthermore, the first light-emitting element 21 and the second light-emitting element 31 each include a light source substrate and a plurality of light-emitting units disposed on the light source substrate, the plurality of light-emitting units can be independently controlled, the light-emitting units include at least four light-emitting units of different colors, and the light-emitting units of different colors are sequentially arranged in a circular pattern on the light source substrate, and can present different brightness and colors according to scene requirements. Such an arrangement makes the light color emitted by the first light-emitting element 21 and the second light-emitting element 31 more uniform, can simulate the color of sunlight at different times, and achieves a dynamic effect of light.

[0040] Specifically, the four-color light-emitting units include a red light-emitting unit, a blue light-emitting unit, a white light-emitting unit, and a green light-emitting unit. Each light source area includes light-emitting units of four colors. The light-emitting units of the four colors are arranged in a circular manner in the light source area. The control system controls the light-emitting units in groups so that each group of light-emitting units can independently adjust the color / brightness; a suitable lighting environment can be created according to different scenes and needs. By accurately controlling the power of the light-emitting units in different areas through the control system, the lamp 100 can achieve continuous changes in light from morning to night, simulating the periodic changes of natural light, and creating a more comfortable and natural lighting atmosphere for users. In other embodiments of the utility model, the four colors of the light-emitting unit 2022 can also be other colors, which are not limited here.

[0041] When the angle between the first light emitting surface 22 and the second light emitting surface 32 is a right angle, the first light emitting surface 22 has a first light emitting aperture 221, the second light emitting surface 32 has a second light emitting aperture 321, the first light emitting aperture 221 is larger than the second light emitting aperture 321, and the illumination range of the first light emitting module 2 is wider than that of the second light emitting module 3, and can cover more spatial areas, avoiding the appearance of shadows. With such a configuration, the first light emitting module 2 can emit more light through a larger light emitting aperture as the main illumination source, while the second light emitting module 3 emits auxiliary light through a smaller light emitting aperture, and the two cooperate with each other to achieve a distinct primary and secondary lighting effect. At the same time, since the second light emitting aperture 321 is smaller, the light it emits is more concentrated, which can form a high-brightness lighting effect in a specific area to meet the needs of local lighting.

[0042] Preferably, when the angle between the first light emitting surface 22 and the second light emitting surface 32 is a right angle, the thickness of the frame 12 is infinitely close to 0, and the lamp 100 can achieve an extremely narrow frame, thereby improving the aesthetics. Since the thickness of the frame is extremely small, the first light emitting surface 22 and the second light emitting surface 32 can be closer to the installation surface, thereby reducing the blocking and loss of light. This allows the light emitted by the lamp 100 to be more directly and evenly irradiated into the space, thereby improving the lighting efficiency and uniformity.

[0043] When the angle between the first light emitting surface 22 and the second light emitting surface 32 is an obtuse angle, that is, the second light emitting surface 32 is inclined, and the first light emitting surface 22 has a first light emitting aperture 221, the second light emitting surface 32 includes a second light emitting aperture 321 away from the first light emitting surface 22 and a third light emitting aperture 322 close to the first light emitting surface 22, and the first light emitting aperture 221 is larger than the second light emitting aperture 321. Moreover, the second light emitting aperture 321 is larger than the third light emitting aperture 322. With such a configuration, the second light emitting module 3 can reduce the light spot and the reflected area formed on the first light emitting surface 22 of the first light emitting module 2 when emitting white light, so that when the light emitting area of ​​the first light emitting module 2 remains unchanged, the sky area observed by people is larger, the visual effect proportion of the sky is increased and the visual effect proportion of the window shadow is reduced, so that a more realistic visual effect can be simulated in a small and medium-sized azure lamp. In addition, since the second light-emitting module 3 is tilted outward, the light emitted by the second light-emitting surface 32 will irradiate downward, and the fill-in light effect is better, which is closer to the light-in effect of the skylight. The light-emitting aperture of the second light-emitting surface 32 gradually increases, and the light will gradually diffuse during the projection process, forming a wider lighting range. At the same time, the gradually increasing light-emitting aperture can also reduce the concentration and glare of light, providing a softer and more comfortable lighting environment.

[0044] like Figure 7 As shown, further explanation is given from the schematic diagram of the lamp cross-section. In the figure, a is the actual frame thickness of the lamp, h is the height of the side wall window shadow, L is the theoretical thickness of the frame 12 (when the angle between the first light emitting surface 22 and the second light emitting surface 32 is a right angle), and L' is the length of the actual light-emitting surface of the side wall window shadow. The length of the first light emitting aperture 221 is R1, the length of the third light emitting aperture 322 is represented by R2, and the length of the second light emitting aperture 321 is represented by R2'. Therefore, R2'=R2+(L-htanθ). That is to say, when θ=0, the second light emitting surface 32 is perpendicular to the first light emitting surface 22. When θ approaches 90°, a approaches 0, which means that the lamp frame approaches 0 at this time, and theoretically an extremely narrow frame can be achieved.

[0045] The lamp 100 also includes an inner frame 121 and a surface light emitting member 23 arranged on the inner side of the frame 12. The first light emitting surface 22 is the side of the surface light emitting member 23 away from the top wall 11, and the surface light emitting member 23 closes the inner frame 121. In addition, the surface light emitting member 23, the top wall 11 and the surface light emitting member inner frame 121 together enclose a first lamp cavity 13 where the first light emitting member 21 is located. The first light emitting member 21 is arranged on the side of the top wall 11 or the inner frame 121 facing the first lamp cavity 13. The light emitted by the first light emitting member 21 is emitted through the surface light emitting member 23. The surface light emitting member 23 diffuses the light and converts the line light source or point light source into a uniform surface light source. In this embodiment, the surface light emitting member 23 is a diffuser 231. The diffuser 231 significantly improves the brightness of the surface light source of the lamp 100, is more energy-saving and environmentally friendly, and makes the light output more uniform. When the first light emitting module 2 is a conventional white light source, nanoparticles are added to the diffuser 231 to form Rayleigh scattering, so that the first light emitting surface 22 appears blue like the sky. In other embodiments, the surface light emitting element 23 may also be a structural element with a microstructure, which is not limited by the present invention.

[0046] In this embodiment, the lamp 100 further includes a transparent plate 232, which is stacked on the side of the surface light emitting member 23 away from the first light emitting module 2. The light emitted by the first light emitting module 2 is projected onto the transparent plate 232 after passing through the surface light emitting member 23. The side of the transparent plate 232 away from the first light emitting surface 22 is a mirror surface. At least part of the light emitted by the second light emitting member 31 is projected onto the transparent plate 232 after passing through the second light emitting surface 32, and is reflected by the transparent plate 232 to form a virtual image 310, so as to simulate the window shadow effect formed on the window when one side of the window is illuminated by sunlight, so that the human eye sees a sense of depth and transparency. At the same time, the transparent plate 232 can also prevent external substances such as dust and moisture from entering the interior of the lamp 100 to protect the first light emitting module 2 and other electrical components.

[0047] Furthermore, the inner frame 121 extends in the direction of the frame 12 to form an outer edge portion 1211, and the frame 12 extends in the direction of the inner frame 121 to form an extension portion 122. The lamp 100 also includes a side light emitting member 33. The side light emitting member 33, the outer edge portion 1211 and the frame 12 are together arranged to form a second lamp cavity 14 where the second light emitting member 31 is located. The second light emitting member 31 is arranged on the side of the outer edge portion 1211 or the frame facing the second lamp cavity 14, and the light emitted by the second light emitting member 31 passes through the second light emitting surface 32 and is emitted in a direction away from the frame 12.

[0048] The side light emitting member 33 includes a step 332 and a light emitting section 333 connected to the step 332, which is recessed inward and extends away from the step 332. The side light emitting member 33 also includes a connecting section 331 abutting against the outer edge portion 1211. The connecting section 331 and the light emitting section 333 are respectively arranged on both sides of the step 332, and the two extend in opposite directions. The connecting section 331 is arranged close to the frame 12 relative to the light emitting section 333. The step 332 connects the connecting section 331 and the light emitting section 333, and is configured to carry the surface light emitting member 23; that is, the surface light emitting member 23 abuts against the step 332. The light emitting section 333 abuts against the step 332 and the extension portion 122, respectively, and is located at the second light emitting surface 32. The second light emitting surface 32 is the side of the light emitting section 333 facing away from the frame 12. The light emitted by the second light emitting member 31 is emitted after passing through the light emitting section 333.

[0049] The first light-emitting component 21 is arranged on the top wall 11 or the inner frame 121 to ensure that the light is evenly diverged from above to form a surface light with a sky effect; the second light-emitting component 31 is arranged on the outer edge 1211 to achieve a side light effect, so that the light has a sense of hierarchy. The lamp 100 also includes a light distribution component 34, which includes any one or a combination of a light guide, a lens, a reflector, and a reflective cup, and can be configured according to lighting requirements. The light emitted by the second light-emitting component 31 is emitted after passing through the light distribution component 34 and the light emitting section 333 in sequence. Through the light guiding effect of the light distribution component 34, the distribution and intensity of the light can be further adjusted and optimized to achieve a more precise and natural lighting effect.

[0050] Specifically, the light distribution member 34 is a light guide member, the extension direction of the light guide member is the same as the extension direction of the light emitting section 333, and is located between the light emitting section 333 and the frame 12. In the extension direction of the light guide member, the two ends of the light guide member are respectively in contact with the light source substrate of the second light emitting member 31 and the extension portion 122 of the frame 12. A reflector 35 is provided on the side of the frame 12 facing the light guide member. The light emitted by the second light emitting member 31 is reflected by the reflector 35 and enters the second lamp cavity 14. Most of the light will be reflected by the reflector 35, ensuring that more light is effectively utilized, thereby improving the light emitting effect. In this embodiment, the reflector 35 is a white matte high-reflectivity powder coated on the side of the frame 12 facing the light guide member.

[0051] Furthermore, there is a gap 4 between the light emitting section 333 and the frame 12. The gap 4 is an air layer, which actually forms a tiny air lens. When light is emitted from the light guide, it passes through the air lens and is refracted and reflected, thereby changing the propagation path of the light, so that more light can be smoothly transmitted from the gap 4, thereby improving the light emission efficiency.

[0052] Preferably, a shading member 36 is provided in the gap 4, and the shading member 36 and the light guide are arranged together around the light emitting section 333, and part of the light emitted by the second light emitting member 31 forms a light emitting area 37 on the light emitting section 333 after passing through the light guide, and part of the light forms a non-light emitting area 38 on the light emitting section 333 after passing through the shading member 36, so as to simulate that when sunlight enters from one side, one side of the window is illuminated, and a dark side is formed on the other side of the window. In addition, the junction between the light emitting area 37 and the non-light emitting area 38 has a light / shadow transition area 39, and a light-dark boundary area formed between the light emitting area 37 and the non-light emitting area 38 can be a continuously changing area from light to dark, or a clear dividing line.

[0053] In the present embodiment, one side where the light guide member and the light shading member 36 are connected has a first inclined surface, and the light shading member 36 is provided with a second inclined surface matching the first inclined surface at a position corresponding to the first inclined surface, and the first inclined surface and the second inclined surface are spliced ​​to form an obvious light and shadow transition line between the light emitting area and the non-light emitting area 38, so that the side light emitting window shadow has a clear cutoff line, making the window shadow effect more realistic.

[0054] Furthermore, the second projection range of the second light emitting surface 32 on the top wall 11 completely falls within the first projection range of the first light emitting surface 22 on the top wall 11, which means that the second light emitting module 3 does not need to completely cover the second lamp cavity 14. Since the shading member 36 and the light guide are circumferentially connected, and the shading member 36 cannot transmit light, the second light emitting module 3 does not need to be arranged above the shading member 36, and only needs to be arranged above the light guide. Thereby reducing the number of light emitting units in the second light emitting module 3, and reducing the cost of the lamp 100.

[0055] In summary, the lamp 100 of the utility model forms a sky-like surface light effect through the first light-emitting module 2, forms a window shadow side light effect through the second light-emitting module 3, and adopts a side light emission method to surround the surface light emission method to simulate the irradiation effect of sunlight. Through structural design, the second projection range of the light-emitting surface of the second light-emitting module 3 on the top wall is controlled to completely fall into the first projection range of the light-emitting surface of the first light-emitting module 2 on the top wall; so that the light-emitting diameter of the first light-emitting module 2 is greater than or equal to the light-emitting diameter of the second light-emitting module 3, ensuring that when the lamp 100 is emitting light, the surface light source of the first light-emitting module 2 and the side window shadow light source of the second light-emitting module 3 can be integrated with each other, avoiding the occurrence of lighting blind spots or shadows, achieving a natural transition of light, and forming a continuous and harmonious lighting effect.

[0056] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
