[0031] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0032] like Figures 1 to 5 As shown, a pinhole imaging structure 10 of one embodiment is used for installation on a building structure. It includes a lamp body 100 and a light-emitting element 200. The lamp body 100 is installed in a mounting hole in the building structure. The lamp body 100 has a communicating mounting cavity 110 and a light-emitting aperture 120. The light-emitting element 200 is disposed within the mounting cavity 110, with its light-emitting end facing the light-emitting aperture 120. The fixed end of the light-emitting element 200 is fixedly connected to the lamp body 100. A printing area 210 is formed on the surface of the light-emitting end of the light-emitting element 200. The projection pattern layer is formed in zone 210 so that the light emitted from the light-emitting end of the light-emitting element 200 can be emitted from the light-emitting hole 120 and illuminate the wall or floor. This allows the pinhole imaging structure 10 to project the pattern on the light-emitting end of the light-emitting element 200 onto the wall or floor through the pinhole imaging principle, which greatly enhances the artistic atmosphere and visual effect of the building and interior space. Compared with traditional projection lamps, the overall structure of the pinhole imaging structure 10 disclosed herein is simpler and more compact, which greatly reduces the assembly difficulty of the projection downlight.

[0033] In this embodiment, when the pinhole imaging structure 10 is working, the light emitted from the light-emitting end of the light-emitting element 200 will be emitted from the light-emitting hole 120 and illuminate the wall or floor. This allows the pinhole imaging structure 10 to project the pattern formed by the projection pattern layer of the light-emitting element 200 onto the wall or floor through the pinhole imaging principle, which greatly enhances the artistic atmosphere and visual effect of the building and interior space.

[0034] The aforementioned pinhole imaging structure 10, with the lamp body 100 used for mounting holes in the building structure, has a connected mounting cavity 110 and a light-emitting aperture 120. The light-emitting element 200 is located in the mounting cavity 110, with its light-emitting end facing the light-emitting aperture 120. The fixed end of the light-emitting element 200 is fixedly connected to the lamp body 100. A printing area 210 is formed on the surface of the light-emitting end of the light-emitting element 200, and a projection pattern layer is formed in the printing area 210. This allows the light emitted from the light-emitting end of the light-emitting element 200 to be emitted from the light-emitting aperture 120 and illuminate the wall or floor. The pinhole imaging structure 10 can project the pattern on the light-emitting end of the light-emitting element 200 onto the wall or floor through the pinhole imaging principle, greatly enhancing the artistic atmosphere and visual effect of the building and interior space. Compared with traditional projection lamps, the overall structure of the disclosed pinhole imaging structure 10 is simpler and more compact, greatly reducing the assembly difficulty of the projection downlight.

[0035] like Figures 1 to 3As shown, in one embodiment, the lamp body 100 includes a light-blocking plate 130, a lamp tube 140, and a heat sink 150. A light-emitting aperture 120 is formed at the center of the light-blocking plate 130. The light-blocking plate 130 is disposed at the first end of the lamp tube 140, and the heat sink 150 is disposed at the second end of the lamp tube 140 and fixedly connected to the lamp tube 140 to form a mounting cavity 110. The fixed end of the light-emitting element 200 is mounted and fixed on the heat sink 150 so that the heat sink 150 can maintain the working temperature of the light-emitting element 200 within the normal working temperature range, thereby ensuring that the light-emitting element 200 can maintain stable normal operation and thus improving the stability of the pinhole imaging structure 10.

[0036] like Figures 1 to 3 As shown, in one embodiment, the connection position between the light-blocking plate 130 and the lamp tube 140 is adjustable, so that the user can adjust the distance between the light-emitting aperture 120 and the light-emitting end of the light-emitting element 200. This allows the user to adjust the clarity and size of the projected pattern by controlling the distance between the light-blocking plate 130 and the light-emitting element 200, thereby improving the applicability of the pinhole imaging structure 10.

[0037] It is understood that in other embodiments, the connection is not limited to a threaded connection, but can also be a sliding connection. For example, the light-blocking plate 130 is coaxial with the lamp tube 140 and is slidably connected.

[0038] like Figures 1 to 3 As shown, in one embodiment, the light-blocking plate 130 is threaded to the lamp tube 140 to further reduce the difficulty of adjusting the light-blocking plate 130.

[0039] like Figures 3 to 4 As shown, in one embodiment, the outer peripheral wall of the light-blocking plate 130 is formed with a first threaded abutment surface 131, and the inner peripheral wall of the first end of the lamp tube 140 is formed with a second threaded connection portion 141 adapted to the first threaded connection portion 131. The first threaded connection portion 131 is threadedly connected to the second threaded connection portion 141, so that when the user rotates the light-blocking plate 130 relative to the lamp tube 140, the light-blocking plate 130 can move closer to or further away from the light-emitting end of the light-emitting element 200 relative to the lamp tube 140, thereby adjusting the distance between the light-emitting aperture 120 and the light-emitting end of the light-emitting element 200. This allows the user to adjust the clarity and size of the projected pattern by controlling the distance between the light-blocking plate 130 and the light-emitting element 200, thereby improving the applicability of the pinhole imaging structure 10. At the same time, it can also reduce the assembly difficulty of the light-blocking plate 130 and the lamp tube 140, thereby improving production efficiency and reducing production costs.

[0040] like Figure 1 and Figure 3As shown, in one embodiment, the aperture of the light-emitting pinhole 120 is 10mm-18mm to avoid the light passing through being too small and the image being too dark. At the same time, it can also avoid the image clarity being poor due to the aperture of the light-emitting pinhole 120 being too large, which greatly improves the applicability of the pinhole imaging structure 10.

[0041] like Figure 3 As shown, in one embodiment, the pinhole imaging structure 10 further includes a fastener (not shown). The fixed end of the light-emitting element 200 has a positioning hole 220, and the heat sink 150 has a threaded hole 152 corresponding to the positioning hole 220. The fastener is set in the threaded hole 152 through the positioning hole 220 and screwed to the heat sink 150, so as to facilitate the installation and removal of the light-emitting element 200, reduce the difficulty of replacing the light-emitting element 200, and thus improve the maintenance cost of the pinhole imaging structure 10. At the same time, users can also change the projection pattern of the pinhole imaging structure 10 by replacing the light-emitting element 200 with different patterns, which greatly improves the applicability of the pinhole imaging structure 10.

[0042] like Figures 1 to 3 As shown, in one embodiment, the pinhole imaging structure 10 further includes a spring clip 300. The second end of the lamp tube 140 is formed with a connecting flange 142. The elastic connecting end of the spring clip 300 is fixedly connected to the connecting flange 142. The snap-fit ​​end of the spring clip 300 is used to snap-fit ​​and fix the pinhole imaging structure 10 to the mounting hole, so that the pinhole imaging structure 10 can be snap-fit ​​and fixed in the mounting hole by the spring clip 300.

[0043] like Figure 3 As shown, in one embodiment, the surface of the light-emitting end of the light-emitting element 200 is positioned directly opposite the light-emitting aperture 120 to ensure that the projected pattern has good integrity and clarity, thereby improving the user experience.

[0044] like Figure 3 As shown, in one embodiment, the cross-sectional area of ​​the light-emitting end of the light-emitting element 200 is smaller than the cross-sectional area of ​​the light-emitting aperture 120, so as to further improve the integrity and clarity of the projected pattern.

[0045] like Figures 1 to 3 As shown, in one embodiment, the heat sink 150 is formed with a wire outlet hole 151 communicating with the mounting cavity 110, so that the wiring harness of the light-emitting element 200 can be connected to an external power source through the wire outlet hole 151, thereby ensuring that the light-emitting element 200 can maintain long-term operation and improving the practicality of the pinhole imaging structure 10.

[0046] like Figures 1 to 3As shown, in one embodiment, a limiting flange 143 is formed on the outer peripheral wall of the first end of the lamp tube 140 so that the lamp tube 140 can be limited by the limiting flange 143 at a preset position of the mounting hole, so that the limiting flange 143 and the spring buckle 300 can cooperate with each other to limit and fix the pinhole imaging structure 10 at the preset position of the mounting hole.

[0047] This disclosure also provides a projection downlight, including the pinhole imaging structure 10 described in any of the above embodiments.

[0048] Compared with the prior art, this disclosure has at least the following advantages:

[0049] The aforementioned projection downlight, with the lamp body 100 used for mounting holes in the building structure, has a connected mounting cavity 110 and a light-emitting aperture 120. The light-emitting element 200 is located in the mounting cavity 110, with its light-emitting end facing the light-emitting aperture 120. The fixed end of the light-emitting element 200 is fixedly connected to the lamp body 100. A printing area 210 is formed on the surface of the light-emitting end of the light-emitting element 200, and a projection pattern layer is formed in the printing area 210. This allows the light emitted from the light-emitting end of the light-emitting element 200 to be emitted from the light-emitting aperture 120 and illuminate the wall or floor. This enables the pinhole imaging structure 10 to project the pattern on the light-emitting end of the light-emitting element 200 onto the wall or floor through the pinhole imaging principle, greatly enhancing the artistic atmosphere and visual effect of the building and interior space. Compared to traditional projection lamps, the overall structure of the pinhole imaging structure 10 disclosed herein is simpler and more compact, significantly reducing the assembly difficulty of the projection downlight.

[0050] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure.
