The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 12, an embodiment of the present application discloses a lamp, which includes a housing 100, a first light emitting assembly 200, a second light emitting assembly 300, and a light intercepting member 400.

In order to enable the light to be emitted from the inside of the housing 100, the housing 100 may have a light outlet 111, so that the light can be emitted through the light outlet 111 to the outside, at least for providing illumination for a user.

The first light emitting assembly 200 is for emitting blue light, wherein the spectral range of the blue light may be 400nm to 500nm. Besides, when the lamp needs to present other colors, the first light emitting assembly 200 can also be used to emit light rays with other colors to satisfy the visual enjoyment of the user.

In some embodiments, the first light emitting assembly 200 may include a blue light emitter 210 and a light guide 220, wherein the light guide 220 is disposed at the light outlet 111, and the blue light emitter 210 is disposed adjacent to the light guide 220 to emit blue light to the light guide 220. In the embodiment of the present application, the light outlet 111 is mainly used to enable light (e.g., sunlight) to be emitted from the inside of the housing 100 through the light outlet 111, so as to prevent the housing 100 from affecting normal light emission.

Optionally, the light guide 220 may have a plate-shaped structure, and may have an incident surface and an exit surface, the incident surface is disposed opposite to the blue light emitter 210, and the exit surface is perpendicular to the blue light emitter 210. Based on this, the blue light emitted by the blue light emitter 210 can be injected into the light guide member 220 through the light incident surface and spread in the light guide member 220, and the blue light is influenced by the internal structure (such as the diffusion particles) of the light guide member 220 in the process of spreading in the light guide member 220, so that the spreading direction of the blue light can be changed, thereby destroying the total reflection condition, further making the blue light be emitted outwards through the light emitting surface, making the light guide member 220 wholly present blue, further making the user experience of viewing the blue sky, and improving the visual enjoyment of the user.

In order to make the blue light emitted by the blue light emitting body 210 enter the light guide member 220, in the embodiment of the present application, the blue light emitting body 210 is disposed at the edge of the light guide member 220, specifically, the blue light emitting body 210 can be disposed at the edge of one end of the light guide member 220, or disposed at the edges of the multiple ends of the light guide member 220, so as to inject the blue light from one end or multiple ends of the light guide member 220. In addition, the edge of the blue light emitting body 210 and the light guide member 220 can be attached or have a certain gap, so that the blue light emitted by the blue light emitting body 210 can enter the light guide member 220, and the blue light can be effectively prevented from escaping from the light guide member 220 to influence the blue sky effect.

Optionally, the spectral range of sunlight is 380nm to 780nm.

The second light emitting assembly 300 may include a plurality of daylight emitters 310 and a plurality of optical elements 320, and the plurality of daylight emitters 310 and the plurality of optical elements 320 are disposed in a one-to-one correspondence manner, so that light emitted by the plurality of daylight emitters 310 may be transmitted through the respective corresponding optical elements 320 to form a daylight spot of a first preset shape. Based on this, after sunlight enters the optical element 320, the sunlight can be limited by the optical element 320 to form a sunlight beam. Alternatively, the optical element 320 may be an optical lens or the like to facilitate the transmission and confinement of sunlight, enabling the sunlight to be emitted in a predetermined direction to form a solar beam.

Further, each optical element 320 may be disposed adjacent to and opposite a corresponding daylight illuminant 310. Optionally, the daylight illuminant 310 may be attached to the light incident surface of the optical element 320 or a gap may be formed between the daylight illuminant 310 and the light incident surface of the optical element 320, so as to ensure that the daylight emitted by the daylight illuminant 310 can enter the optical element 320, and effectively prevent the daylight from escaping from the optical element 320 to affect the daylight effect. Alternatively, the daylight illuminant 310 may be a daylight LED or the like.

In order to obtain the sunlight spot with the second preset shape, the embodiment of the present application further includes a light intercepting member 400 disposed in the housing 100, where the light intercepting member 400 is disposed opposite to the plurality of optical elements 320, and is used for intercepting the sunlight spot with the first preset shape formed by the plurality of sunlight emitters 310 passing through the plurality of optical elements 320, so as to intercept the sunlight spot with the second preset shape, thereby meeting the actual requirement.

In addition, when the sunlight beam passes through the light-intercepting member 400, a light shadow can be formed around the formed sunlight spot with the second preset shape, the brightness of the middle area of the light shadow is stronger, and the brightness of the peripheral area of the light shadow is weaker, so that the purpose similar to a window shadow effect can be achieved.

In the embodiment of the present application, the blue light emitter 210 can emit blue light, and the blue light enters the light guide member 220 and is uniformly emitted from the light guide member 220 after being transmitted, so that the light guide member 220 presents sky blue to present a blue sky light effect, thereby simulating the color of the sky; moreover, the daylight illuminant 310 can emit daylight, and the daylight enters the optical element 320 and is transmitted through the optical element 320 and then is emitted out to form a daylight spot, considering that the second light-emitting assembly 300 includes a plurality of daylight illuminants 310 and a plurality of optical elements 320, so that a plurality of daylight spots can be formed, and the plurality of daylight spots are overlapped to form a daylight spot of a first preset shape; by arranging the light-intercepting member 400, the sunlight spot with the first preset shape can be intercepted to obtain the sunlight spot with the second preset shape, and meanwhile, when the sunlight passes through the light-intercepting member 400, a light shadow is formed around the sunlight spot, and the light shadow is similar to a window shadow generated by sunlight irradiating a window.

Based on the setting, people can observe the light and shadow effect of blue sky light efficiency and sunlight through the lamps and lanterns in this application embodiment simultaneously to can contrast blue sky effect through the light and shadow effect, so that further increase the sense of reality of blue sky effect, and then promote people's vision enjoyment.

Referring to fig. 5-8, in some embodiments, the light emitted by the single helioemitter 310 is transmitted through the optical element 320 to form an elliptical shaped daylight spot, as shown in fig. 7 and 8, and the plurality of elliptical shaped daylight spots are arranged and superimposed to form a quasi-rectangular shaped daylight spot, as shown in fig. 7 and 9. It should be noted here that after the light emitted by the single daylight illuminant 310 is transmitted by the optical element 320, an elliptical daylight spot is formed, and the second light emitting assembly 300 includes the plurality of daylight illuminants 310 and the plurality of optical elements 320, in this case, when the plurality of elliptical daylight spots are arranged in rows and/or overlapped, a similar rectangular daylight spot can be spliced by the plurality of elliptical daylight spots, and the similar rectangular daylight spot has a larger area and higher brightness than the elliptical daylight spot, so that a better daylight effect can be exhibited to a user.

In addition, the above-mentioned rectangular-like sunbeams are understood to be not strictly rectangular in shape, but shaped like a rectangle, e.g., rounded rectangular sunbeams, circular-arc-sided rectangular sunbeams, etc.

In other embodiments, after the light emitted by the single solar light emitter 310 is transmitted through the optical element 320, other shapes of solar spots can be formed, and the shape of the optical element 320 can be specifically designed according to actual requirements, so that the shape of the emitted solar spot meets the requirements. It should be noted that the principle of how to form the oval-shaped solar spot, the light propagation path, the specific structure of the optical element 320, and the like can be referred to herein, and will not be described in detail herein.

Furthermore, the oval sunlight spots are sequentially arranged along the short axis direction, and at least part of two adjacent oval sunlight spots are overlapped. Specifically, the second elliptical day light spot is overlapped and overlapped with at least part of the first elliptical day light spot, the third elliptical day light spot is overlapped and overlapped with at least part of the second day light spot, and so on, and finally, a plurality of elliptical day light spots sequentially arranged along the short axis direction are spliced together to form a large rectangular-like day light spot so that the rectangular light spot is intercepted on the rectangular-like day light spot by a subsequent light intercepting piece.

Based on the setting, this application embodiment need not to carry out the intercepting respectively to every oval day facula, but carry out whole intercepting to the class rectangle day facula that a plurality of oval day facula splice become, compare in single day luminous element and send circular day facula, and carry out the mode of intercepting respectively to every circular day facula, the efficiency of intercepting facula in this application embodiment is higher, and can guarantee that the rectangle facula of intercepting taking out is comparatively clear, thereby can effectively alleviate the problem that the intercepting inefficiency that leads to is carried out the intercepting respectively to single circular day facula, and can effectively alleviate and intercept the easy ghost that appears and lead to the unclear problem in edge to a plurality of circular facula simultaneously.

Further, the area of the first of the two adjacent elliptical solar spots coinciding with the second is S ₀ The area of the first and second offset (i.e., non-overlapping area) is S ₁ Wherein S is ₀ And S ₁ The ratio of 1: (0.5-1.1). The method specifically comprises the following steps: 1. Based on this, two adjacent elliptical solar spots can be madeThe overlapping area is relatively large, so that the effective area of the quasi-rectangle can be large enough, and the rectangular light spot with a larger area can be intercepted subsequently.

In some embodiments, the elliptical diurnal spot has a horizontal angle of 5 ° to 30 ° and a vertical angle of 30 ° to 60 °. Based on this, two adjacent elliptical solar light spots have a large enough overlapping area.

In order to obtain the second predetermined shape of the sunlight spot, in some embodiments, the light-blocking member 400 can be designed as a physical light-blocking sheet, which at least partially blocks the sunlight beam emitted from the optical element 320, and the unblocked sunlight beam passes through the light-blocking member 400 to form the second predetermined shape of the sunlight spot.

Further, the physical light-intercepting sheet may be provided with a rectangular through hole 410, the light exit surfaces of the optical elements 320 are all arranged opposite to the rectangular through hole 410, and the physical light-intercepting sheet intercepts the quasi-rectangular sunlight spot through the rectangular through hole 410 to form a rectangular sunlight spot, as shown in fig. 7 and 10 to 12. Thus, a part of sunlight beams emitted by the optical elements 320 passes through the rectangular through hole 410 to form sunlight spots, and the other part of the sunlight beams cannot pass through due to the blocking effect of the physical light-intercepting sheet, so that sunlight spots in a second preset shape can be intercepted from sunlight spots in a first preset shape (namely, similar to rectangular sunlight spots) through the physical light-intercepting sheet, wherein the sunlight spots in the second preset shape are rectangular sunlight spots, and the rectangular sunlight spots are sunlight spots in a required shape, and further the actual requirements are met.

It should be noted here that, since part of the solar beam is blocked by the physical light-intercepting sheet, the area of the solar spot of the second preset shape is smaller than that of the solar spot of the first preset shape; and, the solar beam forms a shadow when passing through the rectangular through-hole 410, so that a window shadow effect can be provided to a user.

Referring to fig. 2, in some embodiments, an included angle θ between the light emitting surface of the optical element 320 and the surface of the light intercepting member 400 ranges from 5 ° to 50 °. The angle specifically includes 5 °, 10 °, 20 °, 30 °, 40 °, 45 °, 50 °, and the like, and of course, other angle values meeting the requirements may also be included. Further, the included angle between the light emitting surface of the optical element 320 and the surface of the light intercepting member 400 ranges from 10 ° to 45 °.

Based on the above arrangement, when the lamp is in a normal use state, the light-emitting surface of the optical element 320 has a certain inclination with respect to the vertical direction, and the light-emitting surface is perpendicular to the optical axis, so that the optical axis of the optical element 320 has a certain inclination with respect to the horizontal direction, and the optical axis of the optical element 320 is inclined toward one side of the light guide 220. Based on this, on one hand, it can be ensured that the solar beam emitted by the optical element 320 can enter the space between the light guide 220 and the inner wall of the housing 100 (i.e., the inner cavity of the first cavity 110 described below) and be superimposed with the blue light emitted by the light guide 220, so that the blue light emitted by the light guide 220 can be clearer, and the reality of the blue-sky effect can be further increased; on the other hand, the solar beam emitted from the optical element 320 can be irradiated to the light guide 220 and overlapped with the blue light inside the light guide 220, so as to increase the reality of the blue-sky effect; on the other hand, the sunlight emitted from the optical element 320 can pass through the light guide 220 and irradiate on the wall surface to form a sunlight spot on the wall surface, so that the reality of the blue-sky effect can be further increased.

In some embodiments, the surface of the light intercepting member 400 and the surface of the light guide member 220 are perpendicular to each other, and thus, the optical element 320 may be inclined toward the side of the light guide member 220 so as to irradiate the sunlight toward the light guide member 220.

In other embodiments, the second light emitting assembly 300 may be further disposed outside the housing 100, or directly disposed on the ceiling, at this time, the sunlight emitted by the second light emitting assembly 300 is intercepted by the light intercepting member 400, and then directly strikes on the wall surface, and a daylight spot of a second preset shape is formed on the wall surface, in this process, the sunlight emitted by the second light emitting assembly 300 and the blue light emitted by the light guiding member 220 intersect with each other, so that a whitish blue light may be formed, thereby facilitating a more realistic color of the simulated sky, and greatly improving visual enjoyment of the user.
