[0001] This utility model relates to an LED projection reflection multi-point imaging module, belonging to the field of lighting technology. Background Technology
[0002] Current stage performances require stage art to achieve innovation and reform. Stage lighting occupies an important position in stage art performances. Stage lighting is an important component of the performance space. It is an artistic creation that involves the comprehensive visual environment lighting design for characters and specific scenes required according to the development of the plot, and aims to reproduce the design intention to the audience in a visual image. It should comprehensively and systematically consider the spatial modeling of characters and plots, strictly follow the modeling rules, and make good use of techniques.
[0003] In existing technologies, multi-point projection is mainly achieved through the following methods:
[0004] Multi-light source array: This method projects light spots using multiple LED beads, which requires a complex circuit control module, resulting in high cost and energy consumption.
[0005] Fixed optical lenses: use static prisms or gratings to achieve beam splitting, but the position of the light spot is fixed and cannot produce dynamic changes, resulting in limited expressive power;
[0006] Manual adjustment structure: Some devices change the position of the light spot by manually rotating the prism, which is cumbersome and cannot achieve real-time dynamic effects, resulting in a response delay. Utility Model Content

Through single-source input, dynamic prism beam splitting, and reflection enhancement design, it achieves low-cost, high-dynamic multi-point imaging effects, thereby improving the performance of lighting.
[0008] The technical solution adopted by this utility model to solve its technical problem is:
[0009] An LED projection reflection multi-point imaging module includes a mounting frame, a light inlet pipe at the bottom of the mounting frame, a cylinder at the top of the mounting frame, a prism inside the cylinder for splitting the light entering from the light inlet pipe, and a drive unit on the mounting frame for driving the prism to rotate.
[0010] Preferably, the mounting frame includes an upper plate and a lower plate, which are fixedly connected by a number of connecting columns and bolts, and the lower surface of the lower plate is provided with a number of mounting columns.

[0017] Using the principle of prism beam splitting, a single LED light source can achieve 3-8 light point outputs, which reduces costs by 60% and energy consumption by 70% compared to traditional multi-light source solutions. The reflector in the light-inlet tube improves light utilization and reduces light loss.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-3 This utility model provides a technical solution:
[0027] like Figure 1 and Figure 2 As shown, an LED projection reflection multi-point imaging module includes a mounting frame. A light inlet pipe 5 is located at the bottom of the mounting frame. The light inlet pipe 5 is made of aluminum alloy, with a cross-section of 50mm × 50mm and a length of 120mm. A cylindrical body 6 is located at the top of the mounting frame. Inside the cylindrical body 6 is a prism 8 that splits the light entering from the light inlet pipe 5. The prism 8 has a polyhedral structure and can be configured with 3, 6, or 8 faces in actual use. It uses K9 optical glass with an anti-reflection coating. The prism 8 is located directly above the outlet of the light inlet pipe 5, receiving and splitting the light. A single incident light beam can be decomposed into 3-8 outgoing beams at different angles. A drive unit is provided on the mounting frame to drive the rotation of the prism 8.
[0028] Furthermore, a lens 7 is provided on the top of the cylinder 6.
[0029] Furthermore, the cylinder 6 and the light inlet pipe 5 are coaxially arranged with a coaxiality error of ≤0.5mm to ensure optical path alignment.
[0030] Furthermore, the mounting frame includes an upper plate 1 and a lower plate 2. The upper plate 1 and the lower plate 2 are made of aluminum alloy with a thickness of 5mm. The upper plate 1 and the lower plate 2 are fixedly connected by several connecting columns 3 and bolts to form a rigid frame. The connecting columns 3 are made of stainless steel with a diameter of 10mm and a height of 150mm. Several mounting columns 4 are provided on the lower surface of the lower plate 2 for overall module fixing and are compatible with standard lamp holder interfaces. A square through hole is opened in the center of the lower plate 2, and a light inlet pipe 5 is welded thereon.
[0031] like Figure 3As shown, the driving component includes a motor 9, which is a DC servo motor with a power of 20W and a speed of 0-300r / min. The output shaft of the motor 9 is equipped with a gear 10. A gear 11 is meshed on one side of the gear 10. The gear 10 has a module of 0.5 and 20 teeth, while the gear 11 has a module of 0.5 and 40 teeth, thus achieving a speed reduction transmission with a reduction ratio of 2:1. A drive ring 12 is connected to the top of the gear 11. The drive ring 12 is connected to the prism 8 through a rod, driving the prism 8 to rotate around the central axis.
[0032] like Figure 2 As shown, the inner cavity of the light inlet pipe 5 has a square structure, and reflective sheets are provided on the inner cavity wall of the light inlet pipe 5. The reflective sheets are made of highly reflective aluminum foil with a reflectivity of ≥95%, which enhances the utilization rate of light through multiple reflections.
[0033] Furthermore, a heat insulation sheet is installed at the bottom of the light inlet pipe 5. The heat insulation sheet is made of high-temperature resistant ceramic material with a thickness of 2mm to prevent external high temperature from affecting the internal components.
[0034] It should be noted that the motor 9 can be adjusted in speed and controlled to move in both directions via an external controller such as a PLC or a stage lighting control console. Combined with the multifaceted structure of the prism 8, it can create dynamic effects such as the flow, diffusion, and convergence of the projected light spots.
[0035] The workflow of this embodiment is as follows:
[0036] During installation:
[0037] The connecting column 3 is fixed between the upper plate 1 and the lower plate 2 with bolts to ensure the frame is horizontal. The mounting column 4 is welded to the preset position of the lower plate 2 for module fixing. The light inlet pipe 5 is welded to the through hole of the lower plate 2. The reflector is pasted into the inner cavity, and the seam overlaps by 5mm to ensure no light leakage. The heat insulation sheet is fixed at the bottom with bolts. The cylinder 6 is welded to the center of the upper plate 1 and aligned coaxially with the light inlet pipe 5. It is calibrated by a laser collimator. The lens 7 is installed in the top slot. The motor 9 is fixed to the lower surface of the upper plate 1 by a bracket. Gear 10 is keyed to the motor output shaft. Gear 21 is installed on the upper plate 1 through a bearing seat to ensure meshing with gear 10. The drive ring 12 is welded to the top of gear 21. One end of the rod is bolted to the drive ring 12, and the other end is fixed to the center screw hole at the bottom of the prism 8 to ensure that the prism 8 can rotate freely.
[0038] When using:
[0039] An external LED light source with a wavelength of 450-650nm and a power of 10-50W enters from the bottom of the light inlet pipe 5. After multiple reflections by the inner cavity reflector, the light intensity is increased to 1.8-2.2 times the original value. The enhanced light enters the cylinder 6 and illuminates the surface of the prism 8. After being refracted by the multi-faceted prism, it is decomposed into 3-8 sub-beams with different angles. The sub-beams are focused by the lens 7 and projected onto the target surface to form multiple light spots. The motor 9 drives the drive ring 12 to rotate through gear 10 and gear 11. The prism 8 rotates synchronously at a speed of 0-30r / min, so that the position of the projected light spot changes in real time, producing dynamic effects such as flow and rotation. The movement speed of the light spot can be changed by adjusting the motor speed to adapt to different scene requirements.
