In addition, it should be further noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

Referring to fig. 1-8, a lamp 100 according to a preferred embodiment of the utility model includes a housing 1, a first light emitting module 2 and a second light emitting module 3 disposed in the housing 1, wherein 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, wherein the side light emitting mode surrounds the surface light emitting mode, and simulates the irradiation effect of sunlight.

The housing 1 comprises a top wall 11 and a rim 12, the rim 12 being connected to the top wall 11 and extending away from the top wall 11. The top wall 11 is adapted for fixed connection to a mounting base (e.g., ceiling, etc.). The top wall 11 is provided with a power supply assembly, the power supply assembly is arranged on one side of the top wall 11 facing the installation foundation, 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 together.

Specifically, the first light emitting module 2 includes a first light emitting element 21 and a first light emitting surface 22, where 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 light emitted by the first light emitting element 21 is emitted in a direction facing 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 a space, so that the whole surface light can be uniformly emitted without a visual dark area by a direct light emitting mode.

The second light emitting module 3 includes a second light emitting element 31 and a second light emitting surface 32, the second light emitting surface 32 is disposed at the inner side of the frame 12, and the second light emitting surface 32 is disposed below the first light emitting surface 22 and extends in a direction away from the first light emitting surface 22, 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.

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, where the second projection range completely falls within the first projection range. By the arrangement, the luminous diameter of the first luminous module 2 is larger than or equal to the luminous diameter of the second luminous module 3, so that the surface light source of the first luminous module 2 and the side window shadow light source of the second luminous module 3 can be mutually fused when the lamp 100 emits light, natural transition of light is realized, and continuous and harmonious illumination effects are formed. The tight combination of face light and side window shadow, the light that the sky lamp sent and the light that the lateral wall window shadow sent can interweave each other, form seamless joint's illuminating effect, avoid appearing illumination blind area or dark spot, provide more comfortable visual experience for the user, also help building warm, harmonious illumination atmosphere. That is, no matter which direction the human eyes observe the sky light, the face light is always tightly fused with the side wall window shadow, coordinated and consistent, and no shadow exists.

Further, 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 light emitting units can be independently controlled, each light emitting unit includes at least four light emitting units of different colors, and the light emitting units of different colors are sequentially and circularly arranged on the light source substrate, so that different brightness and colors can be presented according to scene requirements. By the arrangement, 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 under different time can be simulated, and the dynamic effect of light is realized.

Specifically, the four-color light-emitting units comprise 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 comprises four-color light-emitting units, the four-color light-emitting units are sequentially and circularly arranged in the light source area, the control system performs grouping control on the light-emitting units, so that each group of light-emitting units can independently adjust color/brightness, and a proper illumination environment can be built according to different scenes and requirements. The power of the light emitting units in different areas is precisely controlled by the control system, the lamp 100 can realize the continuous change of light rays from morning to night, the periodic change of natural light rays is simulated, and a more comfortable and natural lighting atmosphere is created for users. In other embodiments of the present utility model, the four colors of the light emitting unit 2022 may be other colors, which is not limited herein.

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, so as to cover more space regions and avoid the occurrence of shadows. So set up for first light emitting module 2 can send more light through great light-emitting aperture, as main illumination source, and second light emitting module 3 sends auxiliary light through less light-emitting aperture, and both mutually support, have realized the illumination effect that the primary and secondary is clear. Meanwhile, as the second light emergent aperture 321 is smaller, the emitted light is more concentrated, and a high-brightness illumination effect can be formed in a specific area, so that the requirement of local illumination is met.

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 to 0 infinitely, and the lamp 100 can achieve an extremely narrow frame, thereby improving the aesthetic property. Because the frame thickness is very small, the first light emitting surface 22 and the second light emitting surface 32 can be closer to the installation surface, and light shielding and loss are reduced. This allows the light emitted from the luminaire 100 to be more directly and uniformly radiated into space, improving illumination efficiency and uniformity.

When the included 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 far 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. The second aperture 321 is larger than the third aperture 322. So set up, the second light emitting module 3 can reduce the facula and the area of reflecting white that form on the first light-emitting surface 22 of first light emitting module 2 when giving out white light for under the unchangeable circumstances of the light-emitting area of first light emitting module 2, the sky area that the people observed is bigger, has improved the visual effect duty cycle of sky and has reduced the visual effect duty cycle of window shadow, thereby makes also can simulate more true visual effect in the blue lamp of medium and small-size. In addition, since the second light emitting module 3 is inclined outwards, the light emitted by the second light emitting surface 32 irradiates downwards, so that the light supplementing effect is better and is closer to the light inlet effect of the skylight. The light emergent aperture of the second light emergent surface 32 gradually increases, and light is gradually diffused in the projection process, so that a wider illumination range is formed. Meanwhile, the gradually-increased emergent aperture can also reduce the concentration and dazzling feel of light, and a softer and more comfortable illumination environment is provided.

As shown in fig. 7, a further explanation is made from a schematic view of a lamp cut-away. 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 right angle), and L' is the length of the actual light-emitting surface of the side wall window shadow. The length of the first aperture 221 is R1, the length of the third aperture 322 is R2, and the length of the second aperture 321 is R2'. So R2' =r2+ (L-htan θ). That is, θ=0, the second light-emitting surface 32 is perpendicular to the first light-emitting surface 22. When θ approaches 90 °, a approaches 0, meaning that the lamp frame approaches 0 at this time, it is theoretically possible to realize an extremely narrow frame.

The lamp 100 further includes an inner frame 121 disposed inside the frame 12 and a surface light-emitting member 23, where the first light-emitting surface 22 is a side surface of the surface light-emitting member 23 facing away from the top wall 11, and the surface light-emitting member 23 encloses the inner frame 121. The surface light-emitting member 23, the top wall 11, and the inner frame 121 together define a first lamp cavity 13 in which the first light-emitting member 21 is disposed. The first light-emitting member 21 is disposed on a side of the top wall 11 or the inner frame 121 facing the first light chamber 13, and the light emitted by the first light-emitting member 21 is emitted through the surface light-emitting member 23, and the surface light-emitting member 23 diffuses the light to convert the linear light source or the point light source into a uniform surface light source. In this embodiment, the surface light emitting member 23 is a diffusion plate 231, and the diffusion plate 231 significantly improves the brightness of the surface light source of the lamp 100, which is more energy-saving and environment-friendly, and simultaneously makes the light emission more uniform. When the first light emitting module 2 is a conventional white light source, the nano particles are added into the diffusion plate 231 to form rayleigh scattering, so that the first light emitting surface 22 presents blue as sky. In other embodiments, the surface light-emitting member 23 may be a structural member having a microstructure, which is not limited in the present utility model.

In this embodiment, the lamp 100 further includes a transparent plate 232, and the transparent plate 232 is stacked on a side of the surface light emitting member 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 part 23, one side of the transparent plate 232 away from the first light emitting surface 22 is a mirror surface, and at least part of the light emitted by the second light emitting part 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 a window shadow effect formed on a window when one side of the window is illuminated by sunlight, so that human eyes look deep and feel and permeability. Meanwhile, the transparent plate 232 may also prevent external substances such as dust, moisture, etc. from entering the inside of the lamp 100 to protect the first light emitting module 2 and other electrical components.

Further, the inner frame 121 extends in the direction of the frame 12 to form an outer edge 1211, the frame 12 extends in the direction of the inner frame 121 to form an extension 122, the lamp 100 further includes a side light emitting member 33, and the side light emitting member 33, the outer edge 1211 and the frame 12 together enclose a second lamp cavity 14 in which the second light emitting member 31 is located. The second light emitting element 31 is disposed at the outer edge 1211 or the side of the frame facing the second lamp cavity 14, and the light emitted by the second light emitting element 31 passes through the second light emitting surface 32 and then is emitted in a direction away from the frame 12.

The side light emitting member 33 includes a step 332 and a light emitting section 333 connected to the step 332 and recessed inward and extending in a direction away from the step 332. The side light emitting member 33 further includes a connection section 331 abutting against the outer edge 1211, the connection section 331 and the light emitting section 333 are respectively disposed on two sides of the step 332, and the extending directions of the connection section 331 and the light emitting section 333 are opposite, and the connection section 331 is disposed near the frame 12. The step 332 connects the connection 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 is respectively abutted to the step 332 and the extension portion 122, and is located at the second light emitting surface 32, where the second light emitting surface 32 is a side surface of the light emitting section 333 facing away from the frame 12, and the light emitted by the second light emitting element 31 is emitted after passing through the light emitting section 333.

The first light emitting member 21 is disposed on the top wall 11 or the inner frame 121 to ensure uniform light emission from above to form surface light emission of sky effect, and the second light emitting member 31 is disposed on the outer edge portion 1211 to realize side light emitting effect such that light has a layered sense. The lamp 100 further includes a light distributing member 34, where the light distributing member 34 includes any one or combination of a light guide, a lens, a reflector, and a reflector cup, and may be configured according to lighting requirements. The light emitted by the second light emitting element 31 is emitted after passing through the light distributing element 34 and the light emitting section 333 in sequence, and the distribution and the intensity of the light can be further adjusted and optimized through the light guiding effect of the light distributing element 34, so that a more accurate and natural lighting effect is realized.

Specifically, the light distribution member 34 is a light guide member, the extending direction of the light guide member is the same as the extending direction of the light emitting section 333, and the light guide member is located between the light emitting section 333 and the frame 12, and two ends of the light guide member respectively abut against the light source substrate of the second light emitting member 31 and the extending portion 122 of the frame 12 in the extending direction of the light guide member. The side frame 12 is equipped with reflector 35 towards the one side of light guide, and the light that the second luminescent part 31 sent passes through reflector 35 and reflects the back, gets into in the second lamp chamber 14, and most light can be reflected by reflector 35, ensures that more light is effectively utilized, has improved the light-emitting effect. In this embodiment, the reflective member 35 is a white matte high-reflectivity powder coated on the side of the frame 12 facing the light guide member.

Further, a gap 4 is provided between the light emitting section 333 and the frame 12. The gap 4 is an air layer, actually forming a tiny air lens. When light is emitted from the light guide member, refraction and reflection can occur through the air lens, so that the propagation path of the light is changed, more light can be smoothly emitted from the gap 4, and the light emitting efficiency is improved.

Preferably, the light shielding member 36 is disposed in the gap 4, the light shielding member 36 and the light guiding member are disposed around the light emitting section 333, a portion of the light emitted by the second light emitting member 31 passes through the light guiding member to form the light emitting region 37 on the light emitting section 333, and a portion of the light passes through the light shielding member 36 to form the non-light emitting region 38 on the light emitting section 333 so as to simulate that when sunlight is incident from one side, one side of the window is illuminated, and a dark surface is formed on the other side of the window. The junction between the light-emitting region 37 and the non-light-emitting region 38 has a light/shadow transition region 39, and a light-dark junction region formed between the light-emitting region 37 and the non-light-emitting region 38 may be a continuously variable light-to-dark region or may be a distinct boundary.

In this embodiment, a first inclined plane is disposed on a side of the light guide member, where the light shielding member 36 is connected to the light guide member, and a second inclined plane matching the first inclined plane is disposed at a position of the light shielding member 36 corresponding to the first inclined plane, and the first inclined plane and the second inclined plane are spliced to form an obvious light-shadow transition line between the light-emitting region and the non-light-emitting region 38, so that a side light-emitting window shadow has a clear cut-off line, and the window shadow effect is more vivid.

Further, the second projection range of the second light emitting surface 32 on the top wall 11 falls completely 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 fill the second light cavity 14. Since the light shielding member 36 is connected to the light guiding member in a circumferential direction, and the light shielding member 36 cannot transmit light, the second light emitting module 3 is not required to be arranged above the light shielding member 36, and only the second light emitting module 3 is required to be arranged above the light guiding member. Thereby reducing the number of light emitting units arranged in the second light emitting module 3 and reducing the cost of the lamp 100.
