【Detailed ways】

For the detailed structure and working principle of the present invention, first please refer to shown in Fig. 2 and Fig. 3:

The present invention provides a light transmission optical system for decoration, which can supplementarily increase the transmission distance at the periphery, and can make the emitted light of the system appearance more saturated and uniform.

This system uses an optical tube 2, which is a flexible tube body 21 with refractive power as the main body. A hollow tube 20 is formed on the cross section of the tube body 21. The hollow tube 20 is inside the light incident surface 200 of the inner circle. Formed by cross-sectional specifications, an optical layer 22 is tightly coated on the outside of the tube body 21, and an optical interface 23 is formed between the optical layer 22 and the tube body 21. The hollow pipeline 20 provides a long linear light guide element 3 pivots.

The light guide element 3 is basically a light guide body, which can be formed into a single light guide element 3 after a plurality of optical fiber filaments are bundled into a bundle. The light guide element 3 is a material for light decoration, so it has a diameter Lost light to escape.

After the radial escaped light beam _B0 generated by the light guide element 3 passes through the optical action of the optical tube 2, part of the light quantity will be distributed on the outer surface of the optical tube 2 to form a decorative light beam Bn.

Above-mentioned optical layer 22 is to be formed with macromolecular material, and it has inward reflection and outward refraction ability, and forms and coats on the exterior of tube body 21 by its macromolecular optical material, so it is because of being hydrophilic and will not Hydrolyzed, so it can be used for long-term wiring in hydrophilic places, such as the bottom of a swimming pool. The light Bn emitted by it can be used as an obvious decorative effect and warning purpose.

Please refer to Fig. 4 again, the optical tube 2 formed by the present invention includes a tube body 21 with refraction and flexibility in the system, and there is an inner circle light incident surface 200 inside to form a hollow pipeline 20 according to the specification. The pipeline 20 provides a pivoting position of the light guiding element 3 .

The light-guiding element 3 itself is formed with a light-incident end, which can accept an external light source (not shown in the figure) to lead in and reflect and advance. When the external traveling light beam B enters, it advances in the core of the light-guiding element 3, and its advancing method is The advancing light beam B utilizes the internal reflection surface 30 of the light guide element 3 to achieve the reflection law, forms a reflected beam Br, uses the component of the reflected beam Br to advance in angle position, and obtains light transmission forward action, and the light guide element 3 is a light decoration For the optical fiber, it must have part of the radial escape light, and it will form part of the outgoing escape beam B ₀ at the position of the internal reflection surface 30, the escape beam B ₀ and the side of the general decorative optical fiber filament To the lighting source.

In the present invention, an optical layer 22 is combined on the outer surface of the tube body 21 in order to form the auxiliary and decorative light Bn for light transmission and advancement, and an optical interface 23 is formed between the optical layer 22 and the tube body 21. The optical interface 23 It has reflection and refraction capabilities, and its reflectivity can be greater than the refractive index. The relative refractive index of the tube body 21 is greater than the optical interface 23. Therefore, the first refracted light Bt ₁ entered by the escaped light beam B ₀ through the inner light incident surface 200 , it forms a first reflected light beam Br ₁ and a part of the second refracted light Bt ₂ that will emerge from the outer surface 220 on the surface of the optical interface 23, and then forms a second reflection by the internal reflection of the inner light incident surface 200 The light beam Br ₂ , the first reflected light beam Br ₁ , the advancing light beam B, and the second reflected light beam Br ₂ have a forward direction, so the light beam generated by the advancing light beam B can be increased and can be transmitted to a farther distance, so that a longer distance light transmission can be achieved Auxiliary, and utilizing the internal refraction power of the tube body 21, the first refracted light Bt ₁ that enters will be filled in the meat part of the tube body 21, so the internal beams are restricted by the meat part (in the thickness) and filled in every three-dimensional Saturation at corners, the effect of saturation can improve the decorative light Bn of the optical tube 2 surface, highly uniform due to the effect of multi-angles is the first basis for uniform light emission in this case.

The optical interface 23 has a refractive index, which will form part of the second refracted light Bt ₂ , and after the second refracted light Bt ₂ is refracted from the optical layer 22, it will form outgoing light Bn on the surface, so regardless of the light guide element 3 How about the uniformity of the lumen? After it passes through the reflection and refraction of the tube body 21, the outgoing light Bn distributed by the optical layer 22 will get a more uniform state, and under the condition of the high reflectivity of the optical interface 23, from the inside The escaped light beam B ₀ entering the circular light incident surface 200 will _be refracted and reflected according to Snell's law, and the extension length of its advancing distance is the angle and Determined by the intensity of the light source.

After the escape light beam B ₀ enters from the inner circle light incident surface 200, it will form the first reflected light beam Br ₁ after being reflected by the optical interface 23, and when the first reflected light beam Br ₁ acts on the surface of the inner circle light incident surface 200, it will The second reflected light beam Br ₂ will be generated according to the internal reflection of the dense medium on the inner light incident surface 200, so that the light beams entered by the escaped light beam B ₀ form a wave-like progress inside the tube body 21, so that a longer distance can be obtained. transmission.

Part of the first refracted light Bt ₁ traveling through the tube body 21 is split and reflected by the optical interface 23 into the first reflected light beam Br ₁ , and part of the first reflected light beam Br ₁ will pass through the inner light incident surface 200 in reverse to form a reflected light beam Br 1 . Outgoing beam Br ₀ , the reflected beam Br ₀ is a component that follows the final orientation of the advancing beam B, so no matter the driving of the first reflected beam Br ₁ or the second reflected beam Br ₂ , includes the reflected beam Br ₀ , The light beam starting from the light guide element 3 can be assisted to advance as long as it is within the critical angle range of any optical surface reflection.

Please refer to Fig. 5 again, the optical tube 2 system of the present invention includes a tube body 21 and an internal light guide element 3, the outer surface of the tube body 21 is combined with an optical layer 22, and the light guide element 3 obtains the traveling light beam B from one end, and travels The escaped beam B ₀ is formed after the radial escape of the beam B, and the escaped beam B ₀ enters the interior of the tube body 21 from the inner light incident surface 200 , and the first refracted light Bt ₁ that enters is formed by the refraction of the optical interface 23 The second refracted light Bt ₂ , the second refracted light Bt ₂ will cross the optical layer 22 and diverge outward, so that the light beam Bn of light decoration effect will be formed on the outer surface 220 of the optical layer 22, wherein the rough structure can be formed on the outer surface 220. On the other hand, with irregular refraction, the light Bn after the second refracted light Bt ₂ emerges can obtain more uniform divergent scattering, which is the basis for the second uniform light emission in this case.

In the present invention, optical particles 4 can be filled inside the optical layer 22. The optical particles 4 are made of metal material or air bubbles. The refracted light Bt ₁ passes through the refraction effect of the optical interface 23, and then hits the position of the optical particle 4, and the second refracted light Bt ₂ reaches the optical particle 4 to produce a diffuse effect by using the curved surface of the granular surface of the optical particle 4 as an infinite angle. , and form a majority of light splitting, the diffused light beam forms a very uniform light range Bn on the outer surface 220, which is the third basis for uniform light emission in this case.

The implementation concept of the above-mentioned optical particle 4 can also be applied inside the tube body 21, so as to achieve the diffusion operation in advance and the concentration of the diffused light beam.

The present invention provides an optical system of an optical tube 2, as shown in FIGS. The light guide element 3 is provided to be pivoted, and the pivot state is a living relationship, so that the light guide element 3 can move freely, and the tube body 21 has refractive power, and an optical layer 22 is tightly combined on the outside of the tube body 21 , so that an optical interface 23 is formed between the tube body 21 and the optical layer 22, and the optical interface 23 has refraction and reflection capabilities, so that the escape light beam _B0 emitted by the light guide element 3 can enter and form a second refraction The light Bt ₂ and the first reflected light beam Br ₁ can form the second reflected light beam Br ₂ through the internal reflection of the inner circle light incident surface 200, so that the auxiliary extended transmission distance can be obtained, and the appearance of the optical tube 2 can be improved. The light intensity Bn is more uniform.

Wherein the tube body 21 and the optical layer 22 can be integrally formed, and the production is completed in a synchronous pumping manner, and the optical layer 22 is made of a polymer material, which tends to have stretchable elastic strain capacity, and the tube body 21 is the same It can be flexible, so when the whole body forms a curved wiring in a light-decorating occasion, when the curvature of the surface of the tube body 21 changes, the optical layer 22 can be tightly combined and deformed simultaneously, so that the integrity of the optical interface 23 can be maintained, and the The light guide element 3 used also has the same flexibility and curvature performance. After the overall coordination, it can be used for water curvature wiring, increase the light transmission distance, and homogenize the decorative light emitted outside. Implementation, it can clearly achieve the implementation requirements, and all kinds of design concepts are equivalent to the design concept of this case.
