[0002] The existing technologies for realizing the dynamic visual effects of building curtain walls mainly include projection, LED display, static decoration materials, etc. However, traditional projection methods all have certain limitations: 1. If using projection mapping technology: By projecting dynamic images onto the surface of the building curtain wall through a high-brightness projector to form variable visual effects. However, during the day, it is interfered by natural light and the projection effect is almost invisible; it can only play images and cannot combine with the building material itself to form an artistic effect of "complementary movement and stillness".

[0003] 2. If using LED display technology: Embedding an LED dot matrix screen on the curtain wall surface to directly display dynamic content. However, the cost of a large-area LED curtain wall far exceeds the budget of traditional curtain walls, and the aluminum plate curtain wall needs to be greatly modified to adapt to the LED module, affecting the original design.

[0004] 3. If using static decoration materials: It cannot achieve the switching between day and night modes or the breathing light effect, and is only suitable for fixed patterns, lacking interactivity.

[0005] Therefore, how to effectively solve the problems that the dynamic visual effect of the building curtain wall can only be presented at night and cannot combine with the building material itself to form an artistic effect of "complementary movement and stillness", or the screen display form is too expensive and exceeds the budget range and conflicts with the existing aluminum plate curtain wall design, or the building curtain wall is only suitable for fixed patterns and lacks interactivity is a technical problem to be solved urgently.

[0028] A device for presenting curtain wall flood mapping, as Figure 1 shown, includes a light box unit 1 and a projection unit 2 disposed in front of the light box unit. The light box unit 1 includes a perforated plate 11 detachably connected to the front of a light source cavity 12 and a back plate 10 at the rear. The perforated plate 11 includes a hole gradient light-transmitting area for presenting the outline of a pattern main body and a non-hole area for projecting pattern details. A number of point light source light strips 13 are detachably connected in the light source cavity 12.

[0029] Specifically, the perforated plate 11 is made of perforated aluminum plate. Holes are drilled in the perforated plate 11 according to the outline of a pattern, such as the outline of a building or a bridge. The outline of the building or the bridge is outlined by a number of holes, and then light is emitted from the holes through the point light source light strips 13 in the light source cavity 12 to prominently display the main outline. Secondly, pattern details, such as human figures and tree textures, are directly projected onto the non-hole area of the perforated plate 11. The non-hole area is an area without holes and is a flat and smooth plane. The projection unit 2 can project a dynamic video onto the non-hole area of the perforated plate 11. During the day, it mainly relies on the effect of the hole gradient light-transmitting area on the perforated plate 11, and the main outline can be clearly displayed. The visual effect during the day requires the best visual distance of 50 - 160 m on the main road and the main square, with a clear outline. At night, the light-emitting effect of the hole gradient light-transmitting area is combined with the static or dynamic projection on the non-hole area, and a breathing dynamic flood effect can be presented, achieving a better flood mapping effect.

Since the width of the back plate 10 is relatively large, a number of auxiliary keels 34 can be added to the back plate 10. As Figure 10 shown, the distance between the auxiliary keels 34 is 625mm.

[0034] Specifically, the diameter of the steel wire rope is 10mm. The vertical keel 16 is made of 2mm thick galvanized square steel keel, with a length of 584mm, a width of 20mm, and a flange width of 18mm.

[0035] On the basis of the above embodiments, as a preferred embodiment, the point light source light strip 13 is arranged in an S shape in the light source cavity 12. The point light source light strip 13 uses 20×20 lamp beads of 0.6 watts @ 90mm, is arranged in a longitudinal S shape at the hole positions, and the adjacent light box light strips are connected in series and connected to the central control system.

[0036] On the basis of the above embodiments, as a preferred embodiment, the light box unit 1 is provided with a number of columns and a number of rows.
