Lamp

[0003] In the conventional technology, the sky lamp is widely used in various commercial and home lighting occasions as a lamp that simulates the natural sky lighting effect. However, there is a common technical problem in the design and use of the sky lamp, that is, the emitting diameter of the surface light is often smaller than that of the side wall window shadow, resulting in the appearance of a visual dark area.

[0004] Specifically, the conventional sky lamp design often focuses on simulating the visual effect of the sky and white clouds, but it is difficult to achieve perfect fusion of the surface light and the side wall window shadow in the implementation process. The problem of uneven surface light leads to uneven distribution of light intensity in the sky part of the lamp during light emission, resulting in a phenomenon of different brightness, which reduces the overall visual experience.

DETAILED DESCRIPTION

[0029] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in detail below with reference to the drawings and specific embodiments.

[0030] Here, it should be noted that, in order to avoid the present application being obscured by unnecessary details, only structures and / or processing steps closely related to the scheme of the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0031] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, method, article or device.

[0032] Referring to FIGS. 1-8, the lamp 100 of the present application comprises a housing 1, a first light-emitting module 2 and a second light-emitting module 3 arranged in the housing 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 window-like side light-emitting effect, the side light-emitting mode surrounds the surface light-emitting mode, simulating the illumination effect of sunlight.

[0033] The housing 1 comprises a top wall 11 and a frame 12 connected with the top wall 11 and extending away from the top wall 11. The top wall 11 is used to be fixedly connected with a mounting base (e.g. a ceiling, etc.). A power supply assembly is arranged on the top wall 11, and the power supply assembly is arranged on the side of the top wall 11 facing the mounting base, and the power supply assembly is electrically connected with 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.

[0034] Specifically, the first light-emitting module 2 comprises a first light-emitting piece 21 and a first light-emitting surface 22, the first light-emitting surface 22 is the side surface of the surface light-emitting piece 23 facing away from the top wall 11, and the light emitted by the first light-emitting piece 21 is emitted in the direction away from the top wall 11 after passing through the first light-emitting surface 22, and the light can be uniformly projected downward to provide main illumination for the space; through the direct light-emitting mode, the surface light can be uniformly emitted as a whole, and there is no visual dark area.

[0035] The second light-emitting module 3 comprises a second light-emitting piece 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 away from the first light-emitting surface 22, and the light emitted by the second light-emitting piece 31 is emitted in the direction away from the frame 12 after passing through the second light-emitting surface 32.

[0036] The first light-emitting surface 22 has a first projection range on the top wall 11, the second light-emitting surface 32 has a second projection range on the top wall 11, and the second projection range falls completely within the first projection range. In this way, 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, which ensures that the surface light source of the first light-emitting module 2 and the side window light source of the second light-emitting module 3 can be fused with each other when the lamp 100 emits light, realizes the natural transition of light, and forms a continuous and harmonious illumination effect. The close combination of the surface light and the side window light enables the light emitted by the sky lamp to interweave with the light emitted by the side window, forming a seamless illumination effect, avoiding the existence of illumination blind area or dark spots, providing a more comfortable visual experience for the user, and also helping to create a warm and harmonious lighting atmosphere. That is, no matter from which direction the person's eye observes the sky lamp, the surface light is always closely combined with the side window light, consistent and without dark shadows.

[0037] Further, the first light emitting part 21 and the second light emitting part 31 each include a light source substrate and a plurality of light emitting units arranged on the light source substrate, the plurality of light emitting units can be independently controlled, the light emitting units include at least four different color light emitting units, and the different color light emitting units are arranged in sequence on the light source substrate, so that different brightness and color can be presented according to the scene requirement. In this way, the light color emitted by the first light emitting part 21 and the second light emitting part 31 is more uniform, the color of sunlight at different times can be simulated, and the dynamic effect of light is realized.

[0038] Specifically, the four colors of light emitting units include red light emitting units, blue light emitting units, white light emitting units and green light emitting units, each light source region includes four colors of light emitting units, and the four colors of light emitting units are arranged in sequence in the light source region. The control system controls the light emitting units in groups, so that each group of light emitting units can be independently adjusted in color / brightness; and a suitable lighting environment can be created according to different scenes and requirements. By precisely controlling the power of the light emitting units in each different region through the control system, the lamp 100 can realize the continuity of the light from morning to night, simulate the periodic change of natural light, and create a more comfortable and natural lighting atmosphere for the user. In other embodiments of the present application, the four colors of the light emitting units 2022 can also be other colors, which are not limited herein.

[0039] When the included 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, which can cover more space regions and avoid the occurrence of dark shadows. In this way, the first light emitting module 2 can emit more light as the main light source through the larger light emitting aperture, while the second light emitting module 3 emits auxiliary light through the smaller light emitting aperture, and the two cooperate with each other to realize the lighting effect of primary and secondary.

[0040] Preferably, when the included 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 approaches zero, and the lamp 100 can realize an extremely narrow frame to improve the aesthetics. Since the frame thickness is extremely small, the first light emitting surface 22 and the second light emitting surface 32 can be closer to the installation surface, reducing the blocking and loss of light. This makes the light emitted by the lamp 100 more directly and uniformly irradiate into the space, improving the illumination efficiency and uniformity.

[0041] When the included angle between the first light exit surface 22 and the second light exit surface 32 is obtuse, that is, the second light exit surface 32 is arranged obliquely, and the first light exit surface 22 has a first light exit aperture 221, the second light exit surface 32 includes a second light exit aperture 321 away from the first light exit surface 22 and a third light exit aperture 322 close to the first light exit surface 22, and the first light exit aperture 221 is larger than the second light exit aperture 321. Moreover, the second light exit aperture 321 is larger than the third light exit aperture 322. In this way, the second light emitting module 3 can reduce the area of the light spot and the reverse white formed on the first light exit surface 22 of the first light emitting module 2 when emitting white light, so that the area of the sky observed by a person is larger under the condition that the light emitting area of the first light emitting module 2 is unchanged, the proportion of the visual effect of the sky is improved, and the proportion of the visual effect of the window shadow is reduced, so that a more realistic visual effect can be simulated in a small and medium-sized cerulean lamp. In addition, since the second light emitting module 3 is inclined outward, the light emitted by the second light exit surface 32 will be downwardly irradiated, the light supplementing effect is better, and the light supplementing effect is closer to the light inlet effect of the skylight. The light exit apertures of the second light exit surface 32 gradually increase, the light rays will gradually diffuse in the projection process, and a wider illumination range is formed. At the same time, the gradually increasing light exit apertures can also reduce the concentration and glare of the light rays, and provide a more soft and comfortable lighting environment.

[0042] As shown in FIG. 7, further explanation is made from the lamp cutaway view. 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 included angle between the first light exit surface 22 and the second light exit surface 32 is a right angle), L' is the length of the actual light emitting surface of the side wall window shadow. The length of the first light exit aperture 221 is R1, the length of the third light exit aperture 322 is represented by R2, and the length of the second light exit aperture 321 is represented by R2'. Therefore, R2' = R2 + (L - h tan θ). That is, when θ = 0, the second light exit surface 32 is perpendicular to the first light exit surface 22. When θ tends to 90°, a tends to 0, which means that the frame of the lamp tends to 0 at this time, and theoretically, an extremely narrow frame can be achieved.

[0043] The lamp 100 further comprises an inner frame 121 arranged inside the frame 12 and a surface light emitting element 23, the first light emitting surface 22 is a side surface of the surface light emitting element 23 facing away from the top wall 11, and the surface light emitting element 23 encloses the inner frame 121. Moreover, the surface light emitting element 23, the top wall 11 and the inner frame 121 of the surface light emitting element 23 together enclose a first lamp cavity 13 in which the first light emitting element 21 is arranged. The first light emitting element 21 is arranged on a side of the top wall 11 or the inner frame 121 facing the first lamp cavity 13, and the light emitted by the first light emitting element 21 is emitted through the surface light emitting element 23. The surface light emitting element 23 diffuses the light to convert the linear light source or the point light source into a uniform surface light source. In the embodiment, the surface light emitting element 23 is a diffusion plate 231, which significantly improves the brightness of the surface light source of the lamp 100, is more energy-saving and environmentally friendly, and makes the light emission more uniform. When the first light emitting module 2 is a conventional white light source, nano particles are added to the diffusion plate 231 to form Rayleigh scattering, so that the first light emitting surface 22 presents a blue color like the sky. In other embodiments, the surface light emitting element 23 can also be a structural element with a microstructure, which is not limited in the present application.

[0044] In the embodiment, the lamp 100 further comprises a transparent plate 232 arranged on a side of the surface light emitting element 23 facing 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 element 23, a side of the transparent plate 232 facing away from the first light emitting surface 22 is a mirror surface, and the light emitted by the second light emitting element 31 is at least partially 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, thereby simulating the window shadow effect formed on the window when one side of the window is illuminated by sunlight, so that the human eye has a deep and transparent feeling. At the same time, the transparent plate 232 can also prevent external substances such as dust and water from entering the inside of the lamp 100 to protect the first light emitting module 2 and other electrical elements.

[0045] Further, the inner frame 121 extends in the direction of the frame 12 to form an outer edge portion 1211, the frame 12 extends in the direction of the inner frame 121 to form an extension portion 122, and the lamp 100 further comprises a side light emitting element 33, the side light emitting element 33, the outer edge portion 1211 and the frame 12 together enclose a second lamp cavity 14 in which the second light emitting element 31 is arranged. The second light emitting element 31 is arranged on a side of the outer edge portion 1211 or the frame 12 facing the second lamp cavity 14, and the light emitted by the second light emitting element 31 is emitted in a direction away from the frame 12 after passing through the second light emitting surface 32.

[0046] The side light exit member 33 comprises a step 332 and a light exit section 333 connected with the step 332 and recessed inwardly and extending away from the step 332. The side light exit member 33 further comprises a connecting section 331 abutting against the outer edge portion 1211, the connecting section 331 and the light exit section 333 are respectively arranged on two sides of the step 332 and extend in opposite directions, and the connecting section 331 is arranged closer to the frame 12 than the light exit section 333. The step 332 connects the connecting section 331 and the light exit section 333 and is configured to bear the surface light exit member 23; that is, the surface light exit member 23 abuts against the step 332. The light exit section 333 abuts against the step 332 and the extension portion 122 respectively, and is located at the second light exit surface 32, which is the side surface of the light exit section 333 facing away from the frame 12, and the light emitted by the second light emitting member 31 is emitted after passing through the light exit section 333.

[0047] The first light emitting member 21 is arranged on the top wall 11 or the inner frame 121 to ensure uniform light emission from above and form a surface light emitting effect of the sky; the second light emitting member 31 is arranged on the outer edge portion 1211 to achieve a side light emitting effect and make the light have a sense of hierarchy. The lamp 100 further comprises a light distribution member 34, which comprises any one or a combination of a light guide member, a lens, a reflector, and a reflective cup, and can be configured according to lighting needs. The light emitted by the second light emitting member 31 is emitted after passing through the light distribution member 34 and the light exit section 333 in sequence, and the light distribution and intensity of the light can be further adjusted and optimized through the light guiding effect of the light distribution member 34, to achieve a more accurate and natural lighting effect.

[0048] 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 exit section 333, and the light guide member is located between the light exit section 333 and the frame 12. In the extension direction of the light guide member, the two ends of the light guide member respectively abut against the light source substrate of the second light emitting member 31 and the extension portion 122 of the frame 12. The side of the frame 12 facing the light guide member is provided with a reflecting member 35, and the light emitted by the second light emitting member 31 enters the second lamp cavity 14 after being reflected by the reflecting member 35. Most of the light is reflected by the reflecting member 35, ensuring that more light is effectively utilized and improving the light emitting effect. In the present embodiment, the reflecting member 35 is white matte high reflectivity powder coated on the side of the frame 12 facing the light guide member.

[0049] Further, the light exit section 333 and the frame 12 have a gap 4 therebetween. The gap 4 is an air layer, which actually forms a tiny air lens. When the light is emitted from the light guide member, it will be refracted and reflected after passing through this air lens, thereby changing the propagation path of the light, so that more light can smoothly pass through the gap 4, improving the light emitting efficiency.

[0050] Preferably, the gap 4 is provided with a light shielding piece 36, the light shielding piece 36 and the light guide piece are jointly arranged to surround the light emitting section 333, part of the light emitted by the second light emitting piece 31 forms the light emitting area 37 on the light emitting section 333 after passing through the light guide piece, and part of the light forms the non-light emitting area 38 on the light emitting section 333 after passing through the light shielding piece 36, so as to simulate that when the sunlight is incident from one side, one side of the window is illuminated, and a dark area is formed on the other side of the window. Moreover, the intersection between the light emitting area 37 and the non-light emitting area 38 has a light / shade transition area 39, and the 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 can be an obvious boundary line.

[0051] In the embodiment, the side where the light guide piece and the light shielding piece 36 meet has a first inclined surface, the light shielding piece 36 is provided with a second inclined surface corresponding to the position of the first inclined surface, and the first inclined surface and the second inclined surface are jointed to form an obvious light / shade 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, and the window shadow effect is more realistic.

[0052] Further, 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 light shielding piece 36 is connected to the light guide piece in a ring shape, and the light shielding piece 36 cannot transmit light, the second light emitting module 3 does not need to be arranged above the light shielding piece 36, and only needs to be arranged above the light guide piece. Therefore, the number of light emitting units in the second light emitting module 3 is reduced, and the cost of the lamp 100 is reduced.

[0053] In summary, the lamp 100 of the present application forms a sky-like surface light emitting effect through the first light emitting module 2, forms a side light emitting effect of a window shadow through the second light emitting module 3, and surrounds the surface light emitting mode with the side light emitting mode to simulate the illumination effect of sunlight. Through the structural design, the second projection range of the light emitting surface of the second light emitting module 3 on the top wall completely falls within the first projection range of the light emitting surface of the first light emitting module 2 on the top wall; 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, so that 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 fused with each other when the lamp 100 emits light, so as to avoid the occurrence of an illumination blind area or a dark shadow, realize the natural transition of light, and form a continuous and harmonious illumination effect.

[0054] The above embodiments are only used to illustrate the technical solutions of the present application rather than limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
