Referring to Fig. 5 to Fig. 8, in some embodiments, the light emitted by a single daylight illuminant 310 is transmitted through the optical element 320 to form an elliptical solar spot, as shown in Fig. 7 and Fig. 8, and a plurality of elliptical solar spots After being arranged and superimposed, a quasi-rectangular solar spot is formed, as shown in Figure 7 and Figure 9. It should be noted here that the light emitted by a single daylight illuminant 310 is transmitted through the optical element 320 to form an elliptical solar spot, while the second light emitting assembly 300 includes a plurality of daylight illuminants 310 and a plurality of optical elements 320. In this case, when multiple elliptical solar spots are arranged in a row and/or superimposed, multiple elliptical solar spots can be spliced into a quasi-rectangular solar spot. Compared with an elliptical solar spot, this type of rectangular solar spot It is said that the area is larger and the brightness is higher, so that it can show users a better daylight effect.

In addition, the above-mentioned quasi-rectangular solar spot can be understood as a shape that is not a rectangle in the strict sense, but a shape similar to a rectangle, for example, it can be a rectangular solar spot with rounded corners, a rectangular solar spot with arc edges, and the like.

In other embodiments, after the light emitted by a single daylight illuminant 310 passes through the optical element 320, it can also form solar spots of other shapes. Specifically, the shape of the optical element 320 can be designed according to actual needs, so that the shape of the emitted solar spot Meet the needs. What needs to be explained here is that for the principle of how to form an elliptical solar spot, the light propagation path, and the specific structure of the optical element 320 , reference can be made to relevant content, and no detailed description will be given here.

Further, a plurality of elliptical solar spots are sequentially arranged along the minor axis direction, and two adjacent elliptical solar spots at least partially overlap. Specifically, the second elliptical solar spot overlaps and overlaps at least part of the first elliptical solar spot, the third elliptical solar spot overlaps and overlaps at least part of the second solar spot, and so on Finally, a plurality of elliptical solar spots sequentially arranged along the short axis direction are spliced together to form a large rectangular solar spot, so that the subsequently passing light-cutting member can intercept a rectangular solar spot on the similar rectangular solar spot.

Based on the above settings, the embodiment of the present application does not need to intercept each elliptical solar spot separately, but conducts overall interception of a rectangular solar spot formed by splicing multiple elliptical solar spots. Compared with a single solar illuminant emitting circular In the embodiment of the present application, the efficiency of intercepting the spot is higher, and it can ensure that the intercepted rectangular spot is relatively clear, so that it can effectively alleviate the problem of targeting a single circular sun spot. The problem of low interception efficiency caused by separate interception can effectively alleviate the problem that simultaneous interception of multiple circular spots is prone to ghosting and unclear edges.

Further, the overlapping area of the first and the second of the two adjacent elliptical sun spots is S ₀ , and the misaligned area of the first and the second (that is, the non-overlapping area) is S ₁ , wherein the ratio of S ₀ to S ₁ is 1: (0.5-1.1). Specifically include: 1:0.5, 1:0.75, 1:0.9, 1:1.0, 1:1.1, etc. The specific ratio can be selected according to the actual working conditions. In addition, it can also be other ratios. This is not specifically limited. Based on this, the overlapping area of two adjacent elliptical solar spots can be made relatively large, so that the effective area of the quasi-rectangular shape can be made large enough, so that a rectangular spot with a larger area can be intercepted later.

In some embodiments, the horizontal angle of the elliptical solar spot is 5°-30°, and the vertical angle is 30°-60°. Based on this, two adjacent elliptical sun spots have a sufficiently large overlapping area.

In order to obtain the solar spot of the second preset shape, in some embodiments, the light-cutting member 400 can be designed as a physical light-cutting piece, which can at least partially block the solar beam emitted by the optical element 320, while the unblocked solar spot After the light beam passes through the light-cutting member 400, a solar spot of a second preset shape is formed.

Further, the physical light-cutting sheet can be provided with a rectangular through-hole 410, and the light-emitting surfaces of the plurality of optical elements 320 are set opposite to the rectangular through-hole 410, and the physical light-cutting sheet intercepts the quasi-rectangular solar spot through the rectangular through-hole 410 to A rectangular solar spot is formed, as shown in Figure 7, Figure 10 to Figure 12. In this way, a part of the sunlight beams emitted by the plurality of optical elements 320 passes through the rectangular through hole 410 to form a solar spot, and the other part is blocked by the physical light-cut sheet and cannot pass through. Therefore, the physical light-cut sheet can pass through the first A solar spot of a second preset shape is intercepted from a solar spot of a preset shape (that is, a rectangular solar spot), wherein the second preset shape of a solar spot is a rectangular solar spot, and the rectangular solar spot is the desired shape The sun spot, and then meet the actual needs.

It should be noted here that, since part of the solar beam is blocked by the physical light-cutting sheet, the area of the solar spot of the second preset shape is smaller than the area of the solar spot of the first preset shape; and, the solar beam When passing through the rectangular through hole 410 , light and shadow will be formed, so as to provide the user with a window shadow effect.

Referring to FIG. 2 , in some embodiments, the angle θ between the light-emitting surface of the optical element 320 and the surface of the light-cutting member 400 ranges from 5° to 50°. It specifically includes 5°, 10°, 20°, 30°, 40°, 45°, and 50°, etc. Of course, other angle values that meet 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-cutting member 400 ranges from 10° to 45°.

Based on the above settings, when the lamp is in normal use, the light-emitting surface of the optical element 320 has a certain inclination relative to the vertical direction, and since the light-emitting surface is perpendicular to the optical axis, the optical axis of the optical element 320 has an inclination relative to the horizontal direction. A certain inclination, so that the optical axis of the optical element 320 is inclined toward one side of the light guide 220 .
