Referring to fig. 5-7, in some embodiments, the light emitted by the single helioemitter 310 is transmitted through the optical element 320 to form an elliptical solar spot, as shown in fig. 7, and the plurality of elliptical solar spots are stacked to form a rectangular-like solar spot. 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 may also be formed, and specifically, the shape of the optical element 320 may be 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 daylight spot, the light propagation path, the specific structure of the optical element 320, etc. can be referred to the relevant contents, 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, can make two adjacent ellipse day facula's coincidence area relatively great to can make the effective area of class rectangle big enough, so that follow-up can intercept the rectangle facula of bigger area.

In some embodiments, the elliptical solar 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 daylight spot of the second predetermined shape, in some embodiments, the light-intercepting member 400 may be designed as a physical light-intercepting member, at least a portion of which may partially obstruct the daylight beam emitted by the optical element 320, and the unobstructed daylight beam forms the daylight spot of the second predetermined shape after passing through the light-intercepting member 400.

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. 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 that, since part of the solar beam is blocked by the physical light-intercepting sheet, the area of the solar spot with the second preset shape is smaller than that of the solar spot with 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.
