[0022] In the technical solution of this utility model, Figure 1 , Figure 2 and Figure 3 This is a structural schematic diagram provided according to the specific structure of a modular curtain-type fiber optic light-emitting device of this utility model, as shown below. Figure 1 , Figure 2 and Figure 3 As shown, this utility model includes:

[0023] The light guide substrate 1, light-emitting panel 2, light-shielding patch 3, optical fiber 4, and light-emitting strip 5 are provided. One end of the light guide substrate 1 is provided with a panel mounting groove 11, and the other end is provided with a focusing groove 12. The light-emitting strip 5 is installed in the focusing groove 12, and the light-emitting panel 2 is installed in the panel mounting groove 11. The light-shielding patch 3 is located on the side of the light-emitting panel 2 facing away from the focusing groove 12. Optical fiber mounting holes 21 are evenly spaced along the length of both the light-emitting panel 2 and the light-shielding patch 3. The optical fiber mounting holes 21 are adapted to the optical fiber 4, and the optical fiber 4 is inserted into the optical fiber mounting holes 21. In this invention, each optical fiber can be replaced individually, reducing maintenance costs.

[0024] like Figure 2 As shown, a light-transmitting surface 13 is provided between the panel mounting groove 11 and the focusing groove 12, and the end face of the optical fiber 4 is attached to the light-transmitting surface 13. This ensures that the end face of the optical fiber 4 is flush with the light-transmitting surface 13. The flush end face and the focusing groove in this invention improve coupling efficiency.

[0025] The light strip 5 is an LED light strip, specifically a 2835 LED light strip.

[0026] The light-shielding patch 3 is made of 0.15 mm black PET with laser-cut array of through holes, each 0.8 mm in diameter and 10 mm in center-to-center distance. This light-shielding patch eliminates light crosstalk and achieves a uniform "light curtain" effect.

[0027] The light guide substrate 1 is made of acrylic material. Specifically, it can be formed by casting transparent acrylic to create a light guide substrate with a thickness of 3mm. Figure 1 In the direction shown, the upper surface of the light guide substrate 1 is machined into a light-concentrating groove by CNC machining, and the bottom surface of the light-concentrating groove is a light-transmitting surface.

[0028] In one embodiment, such as Figure 2 and Figure 3 As shown, the focusing groove 12 is V-shaped. Specifically, the width of the focusing groove 12 near the light-transmitting surface 13 is smaller than the width away from the light-transmitting surface. Fixing plates (not shown) are provided at both ends of the light guide substrate 1 along its length. The two ends of the light-emitting strip 5 are fixed to these fixing plates and can be connected by adhesive or other methods to secure the light-emitting strip.

[0029] In one embodiment, such as Figure 4As shown, the width of the focusing groove 12 near the light-transmitting surface 13 is greater than the width away from the light-transmitting surface, and the light-emitting strip 5 is installed at the bottom of the focusing groove 12. A heat dissipation shell 51 is provided on the side of the light guide substrate 1 facing away from the light-emitting strip 5. Specifically, a mounting plane is provided at the bottom of the focusing groove of the light guide substrate 1, and the light-emitting strip 5 is installed on the mounting plane, facing the light-emitting panel 2. A heat dissipation shell 51 is provided on the back of the mounting plane to dissipate the heat of the light-emitting strip 5 to the outside of the light guide substrate 1.

[0030] The light-emitting panel 2 has a 5% light transmittance scattered dot pattern silkscreened on the side near the light-transmitting surface 13. The light-emitting panel 2 is made of semi-transparent frosted polyurethane material. Specifically, it is a 2 mm semi-transparent frosted PC light-emitting panel.

[0031] The end face roughness of the optical fiber 4 is ≤5μm. The optical fiber 4 has an outer diameter of 1.0 mm and is a side-emitting PMMA. After grinding and flame polishing, the roughness Ra of the end face is ≤5μm.

[0032] The light-emitting panel 2 and the panel mounting groove 11, as well as the light-emitting panel 2 and the light-shielding patch 3, are fixed together by vacuum pressing with optically curable adhesive. The optically curable adhesive is a 0.1 mm UV-curable optical adhesive with a refractive index of 1.48 and a light transmittance of ≥92%.

[0033] The outer wall of the light guide substrate 1 is provided with a connection structure for fixing, wherein the connection structure can be a dovetail groove structure or a magnetic structure. Specifically, it can be an anodized aluminum dovetail groove or an NdFeB magnetic base, realizing tool-free splicing. The dovetail groove or magnetic base can realize the rapid connection of the light guide substrate. The dovetail groove or magnetic structure can realize rapid installation on a 1 m² wall in 10 minutes.

[0034] The manufacturing process of this utility model is as follows: material preparation and microstructure processing; synchronous drilling to ensure coaxiality ≤ 0.05mm; vacuum lamination at 50 ℃ / 0.6 MPa / 10 min, UV curing; fiber threading, end face treatment, welding of quick-connect terminals; aging at 55 ℃ / 85% RH for 24 h and testing.

[0035] During on-site installation, several light guide substrates are slid into the dovetail groove or magnetically fixed to the metal track to complete the large-area fiber optic curtain layout. If a single fiber is damaged, simply pull out the old fiber, insert the new fiber, and cut it to the required length; there is no need to disassemble the entire board.

[0036] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
