Abstract

A light guide strip structure with neon effect comprises a transparent body, wherein the body comprises a surface capable of scattering light and a color band arranged in the body; the reflectivity or index of the color band is larger than that of the body, so that most of light rays are forced to be reflected back to the body, and partial light rays enter the color band to generate a neon effect. In essence, the light entering the body travels along the direction of the body axis, producing reflection and refraction between the body and the ribbon, and scattering the light out of the body surface; the invented method can improve the brightness of light guide, improve the blurring of luminous effect in the old method, and reduce the bright and dark bands or diffraction phenomena generated by the known structure and the interference of luminous effect.

Description

Light guide structure with neon effect

Technical field:

The present invention relates to a light guide structure; in particular, it refers to a composite color ribbon of a light guide body, which enables light to produce neon effects and more ideal reflection and refraction effects between the body and the ribbon.

Background technique:

Use thermoplastics, such as polymers such as polycarbonate, polyurethane, ethyl, methacrylate or similar materials to make a transparent core or core, and coat the surface of the core or core It is a known technology that a protective layer or a thin coat made of polyethylene material is used to guide the light guide structure together. For example, US Patent No. 4,422,719 "OPTICAL DISTRIBUTION SYSTEM INCLUDING LIGHT GUIDE" discloses a typical embodiment. It discloses a technology that combines a transparent core body with a translucent sleeve; the design of the sleeve is to make its refraction greater than that of the core body to increase the reflection of light and extend the light The travel distance within the core body, and make the scattered or diffused light uniform and soft. However, the coat makes the diffused light hazy, blurred, loses its brightness, and makes the diffused light less beautiful; this has been proved by its products.

Another factor that makes scattered light hazy and blurred may also include that the inner surface of the mantle and the surface of the core are two very close surfaces; light reflected from one surface is likely to be reflected from the other surface interference of light rays cancels out. For example, assuming that the light source is white light, when the thickness of the coat is thinner, it is easy to make the blue light in the white light cancel due to interference, so the light reflected into the eyes will become a less bright yellow light (that is, the complementary color of blue light); If the thickness of the coat is increased, the green light in the white light is easily offset, and its corresponding complementary color appears. In other words, the light guide structure of the jacket covering the core will reduce the brightness of the light due to this interference phenomenon.

In order to improve this kind of problem, the No. 4,422,719 patent provides other embodiments; for example, setting scores arranged in different lengths on the jacket and the core body, or adding photosensitive emulsion and reflective powder materials that can increase brightness in the jacket or metal oxides. However, these embodiments also make the light guide structure more complicated to manufacture.

In patent cases such as U.S. Patent No. 6,169,836 B1 "OPTICAL TRANSMISSION TUBE AND METHOD FOR MAKING THE SAME" and U.S. Patent No. 7,433,565 B2 "SIDE-SCATTERING LIGHT GUDES", the application of a protective layer or a jacket to cover the core body is also disclosed. Technical means; said patent is to make the refractive index (refractive index) of the core body greater than the refractive index of the jacket. However, the protective layer or coat will also make the scattered light hazy, blurred, reduce the brightness of the light, and make the scattered light less beautiful; and this situation is also obtained from their products. prove.

Therefore, in order to improve the brightness of their light-guiding structure, they set a lot of crystals made of organic polymers (such as silicone resin molecules, polystyrene resin, metal oxides, carbonates or similar materials, etc.) inside the core body. Scattering particles (light-scattering particles) or diffuser particles (diffuser particles) to increase the reflection and refraction of light. As known to those skilled in the art, such light guiding structures with scattering or diffusing particles are relatively complex to manufacture. Because, after they add the already manufactured scattering particles into the core body in a dissolved state and through polymerization, they must go through a vibration and rotation operation to make the scattering particles scatter inside the core body. The manufacture of this type of structure is reflected in the price, making the price of each 20cm light guide structure as high as NT$70-80.

Another issue related to the application of this type of light-guiding structure with scattering particles or diffusing particles is that when the light entering the core encounters these scattering particles or diffusing particles, it usually also passes through the scattering particles or diffusing particles. The back of the shadow creates a shadow, so that the edge of the shadow produces diffraction fringes; sometimes the diffraction fringes are mixed together, making the edge of the shadow blurred. Although the degree of diffraction depends on the relationship between the size of scattering particles or diffuse particles and the wavelength of light (for example, the longer the wavelength, the more obvious the diffraction), but it also shows that the choice or use of the light source is limited , which is not what we expect.

Also disclose another embodiment in this No. 7,433,565 B2 patent case, it is provided with an air layer or the dielectric layer that other similar materials are formed between core body and outer jacket; The refractive index of air layer or dielectric layer is smaller than that of core body refractive index. Because there is a layer of air between the core body and the jacket, the light will be reflected from the top and bottom of the air layer, and this reflected light will interfere with each other, resulting in bright and dark bands (that is, light and dark stripes). This is because the light reflected into the eye comes from two different paths, the light reflected from the inner surface of the coat and the light reflected from the outer surface of the core; the light reflected from the outer surface of the core has to travel a longer distance to reach the viewer's eye. Eye. If this distance difference is exactly half a wavelength (out of phase), destructive interference will occur and a dark band will appear; if the distance difference next to it does not interfere, a bright band will appear. That is to say, the light reflected from the two very close planes of the inner surface of the coat and the outer surface of the core will produce interference fringes and reduce the brightness of the light.

Representatively speaking, these reference data show the technologies related to the application of light sources and light guiding structures; they also reflect some problems in the design of these light guiding structures in some application situations. If the organization structure of the light guide is redesigned to make its structure different from the known ones, its use pattern will be changed, which is different from the old method; in essence, its application range will also be increased. But how to overcome or improve the shortcomings we discussed above? For example, make its structural design meet a simple condition, and at the same time have the effect of reducing the bright and dark bands and diffraction phenomena of known structures, and interfere with the luminous effect; or further improve the brightness of the light guide, and improve the luminous effect in the old method. ambiguity; we found that its construction had to take into account the following design issues:

1. It should be different from the above-mentioned patent cases (US 4,422,719, US6,169,836 B1, US7,433,565 B2) to set the structure organization and design direction of the coating protective layer or coat on the surface of the core body; in order to reduce the blurred or unclear luminous effect situation.

2. The US4,422,719, US6,169,836 B1, US7,433,565 B2 and other patent cases should be abandoned, and the structure of scattering particles or scattering particles should be dispersed inside the core body to reduce shadows or diffraction fringes, and further allow the light source The selection or use of types is not limited; and the manufacturing cost and complexity of the light guide structure are reduced.

3. In order to maintain or increase the reflection and refraction of light, the internal structure of the light guide strip should be rearranged and designed.

4. As the above two planes that are very close to each other (for example, the inner surface of the jacket and the surface of the core body), the area where they are close to each other should be reduced as much as possible to reduce the destructive interference of the reflected light from the two planes or the situation of producing bright and dark bands .

None of these issues are taught or specifically disclosed in the above references.

Invention content:

The technical problem to be solved by the present invention is: aiming at the deficiencies of the above-mentioned prior art, provide a neon-effect neon-effect lamp with simple manufacture and structure, which can reduce bright and dark bands or diffraction phenomena and disturbing luminous effects produced by known structures. Light guide structure.

In order to solve the above technical problems, the technical solution adopted in the present invention is: a light guide strip structure with neon effect, which can guide the light to travel, including a transparent body and a color ribbon arranged in the body. The body defines a central axis and a surface that can scatter light; its characteristic is: the ribbon is arranged on the central axis of the body, and the cross-sectional area ratio of the body to the ribbon is about 20:1-90:1, and the ribbon The reflective index is greater than that of the body, so that most of the light is reflected back to the body, and a relatively small part of the light enters the ribbon, resulting in a neon effect.

According to the light guide strip structure with neon effect of the present invention, the body is a tubular or columnar structure defining a central axis; the ribbon is arranged on the central axis of the body. Therefore, the destructive interference or bright and dark bands produced by the reflected light of the body and the ribbon are minimized as much as possible.

According to the light guide strip structure with neon effect of the present invention, the color ribbon is arranged inside the main body in the form of several sections or strips. In a modified embodiment, the ribbons are arranged at intervals along the axis.

According to the light guide strip structure with neon effect of the present invention, the body can be composed of two halves; each half has a plane, and at least a color band is arranged on the plane of the half. Specifically, the ribbon can be arranged or printed on the plane of one of the half bodies, and the two halves can be combined into an integral state.

In this way, it can significantly reduce the blurred or unclear luminous effect of the light guide strip as in the old method; it can significantly reduce the phenomenon of shadows or diffraction fringes, and further prevent the selection or use of light source types from being restricted; and, reduce The manufacturing cost and complexity of the light guide structure significantly improve the situation where the known two-plane reflected light destructively interferes or produces bright and dark bands. And in order to maintain or increase the reflection and refraction of light, a colored ribbon is arranged inside the body; it can display a special visual effect of the light guide strip structure during the day; and it can be used when the light source enters the light guide strip After the structure, it diffuses beautiful, clear light and neon effects in day and night respectively.

The novelty, characteristics, and other purposes and effects of the present invention will be explained in detail below in conjunction with the attached drawings, and tend to be understood; as shown in the figure:

Detailed ways:

Please refer to FIG. 1 and FIG. 2 , the light guide strip structure with neon effect of the present invention includes a combination of a body and at least one color band, which are denoted by reference numerals 10 and 20 respectively. Body 10 has selected transparent plastics, methacrylic resin (PMMA), polyurethane, glass, resin, thermoplastics or similar materials to make (in the known technology, many kinds of materials for making the body have been disclosed, so will not be described in detail); in a preferred embodiment, the main body 10 tends to form a transparent flexible body with good refractive power and transmission power (or transmission power). In the embodiment taken, the body 10 has chosen a circular profile, defining a central axis 11 and a surface 12 capable of scattering light. It can be understood that the body 10 can also adopt other geometric shapes.

In the adopted embodiment, the ribbon 20 is inserted into the main body 10 in the form of a colored ribbon or ribbon; specifically, the ribbon 20 is arranged on the axis 11 of the main body 10 . Ribbon 20 may also be plated with silver or the like to increase its reflectivity. In the example taken, the color of red is chosen for the ribbon 20 . The reflectivity or index of the ribbon 20 is greater than that of the main body 10, so that most of the light is reflected back to the main body 10, but a small part of the light is allowed to enter the ribbon 20 to produce a neon effect. The ribbon 20 tends to be made of materials with low light absorption and high transmittance, such as cross-linked polymers; allowing light to travel along the body 10 and the ribbon 20 with high transmission ability or efficacy.

In a feasible embodiment, the ratio of the sectional area of the body 10 to the ribbon 20 ranges from about 20:1 to 90:1; FIG. 2 shows that the ratio of the sectional area of the body 10 to the ribbon 20 is about 60. : 1 situation. Therefore, the destructive interference or bright and dark bands produced by the reflected light of the main body 10 and the ribbon 20 are minimized as much as possible.

Please refer to Fig. 3, when the light source S enters from one end 13 of the light guide strip, the light can pass along the light guide strip in a straight line in the direction parallel to the axis 11 of the body 10; part of the light hits the body surface 12 and the ribbon 20, reflection and refraction will occur inside the main body 10. When the incident angle (the angle between the incident ray and the normal N) of any beam of light hitting the body surface 12 (or the ribbon 20) is less than the critical angle (the minimum incident angle at which the light is totally reflected in the light guide strip) , part of the light will be refracted out of the body 10 , and produce beautiful scattered or diffuse light on the surface 12 of the body.

Referring to FIG. 3 and FIG. 4 , five rays or rays 30 , 40 , 50 , 60 , 70 are used for illustration. For example, when the angle at which the light 30 enters the body 10 and reaches the body surface 12 is smaller than the critical angle, part of the light will be refracted out of the body 10 , and a beautiful scattered or diffuse light 31 will be produced on the body surface 12 . A portion of the light 32 is reflected onto the ribbon 20 producing scattered or diffuse light 33 on the ribbon 20 . The ribbon 20 reflects part of the light 34 to the surface 12 of the main body; however, a small part of the light 35 is refracted into the ribbon 20 . The path of the light 35 is deflected toward the normal N; a part of the light 36 refracts the color ribbon 20 toward the direction away from the normal N, and shoots to the surface 12 of the body; The direction of the normal N refracts the color band 20 towards the body surface 12 . The light 37 also has part of the light 38 forming a reflection state in the ribbon 20 .

Please refer to FIG. 5 , when the angle at which the light 40 enters the body 10 and reaches the surface 12 of the body is equal to the critical angle, the light 41 will pass through the surface 12 of the body. If the angle at which the light 40 enters the body 10 and reaches the surface 12 of the body is greater than the critical angle, the light 42 will be totally reflected on the ribbon 20 and then totally reflected away from the ribbon 20 . In another situation, the light 42 may also generate diffuse light 43 on the ribbon 20; The path of the light 44 is deflected toward the normal N; a part of the light 45 refracts the color band 20 toward the direction away from the normal N, shoots to the body surface 12, and then produces scattered or diffuse light 46 on the body surface 12; After the light 47 is reflected in the color ribbon 20 , it also refracts the color ribbon 20 in a direction away from the normal N, and shoots toward the surface 12 of the main body. The light 47 also has part of the light 48 forming a reflection state in the ribbon 20 .

It can be understood that the traveling conditions of the light rays 60 and 70 are the same as those of the above-mentioned light rays 30 and 40 respectively; therefore, no further description is given.

Referring to Fig. 6, the cross-sectional view of the ribbon 20 is enlarged, and the two sides of the ribbon 20 are defined, respectively indicated by reference numerals 21 and 22; the situation where the light 50 enters the ribbon 20 is illustrated by rays 51, 52, and 53 respectively . Basically, light 53 travels in a straight line within ribbon 20 .

Assuming that the angle at which the light 51 enters the ribbon 20 is smaller than the critical angle, part of the light 51a will deviate from the normal N to refract the ribbon 20 and enter the body 10 , and also produce scattered or diffuse light 51b on the ribbon 20 . Part of the light 51c will be reflected on the other side 22 of the ribbon 20, so that part of the light 51d will deviate from the refraction of the normal N to the ribbon 20 and enter the main body 10; the light 51c will also be scattered or diffused on the side 22 of the ribbon 20 Ray 51e. A part of the light 51f is reflected in the ribbon 20 and goes to the other side 21 of the ribbon 20 .

Referring to FIG. 6 again, assuming that the light 52 enters the ribbon 20 at an angle equal to the critical angle, the ray 52a will graze the surface or edge 21 of the ribbon 20 . If the angle at which the light 52 enters the ribbon 20 is greater than the critical angle, the light 52 b will be totally reflected to the other side 22 of the ribbon 20 .

Above, after the light source S enters the light guide strip, the refraction and reflection of the light rays 30 , 40 , 50 , 60 , and 70 in cooperation with the body 10 and the ribbon 20 are described. But because the sectional area ratio of the body 10 and the ribbon 20 ranges from about 20:1 to 90:1; in fact, some light will pass through the ribbon 20 without refraction or reflection on the ribbon 20 . In Figure 7 below, the transmission of these light rays across the ribbon 20 will be illustrated. The rays are indicated with reference numerals 80, 90, respectively.

Please refer to FIG. 7 , which defines the body surface 12 and has two sides in the figure, denoted by reference numerals 14 and 15 respectively.

Assuming that the angle at which the light 80 enters the body 10 is smaller than the critical angle, part of the light 81 will deviate from the normal N and be refracted out of the body 10 , and also produce scattered or diffuse light 82 on the surface 12 of the body. Part of the light 83 will cross the ribbon 20 and reflect to the other side 15 of the main body 10, so that part of the light 84 deviates from the normal N and refracts out of the main body 10; the light 83 will also generate scattered or diffuse light on the side 15 of the main body 10 85. A part of the light 86 is reflected in the main body 10 and goes to the other side 14 of the main body 10 . If the light 90 enters the main body 10 at an angle greater than the critical angle, the light 91 will cross the ribbon 20 and be totally reflected to the other side 15 of the main body 10 .

Please refer to FIG. 8 , in a derivative embodiment, the ribbons 20 may be arranged at intervals in the direction of the axis 11 of the main body 10 . In another modified embodiment, the ribbons 20 are disposed inside the main body 10 in the form of several parallel strips or sections; for example, the situation depicted in FIG. 9 .

Please refer to FIG. 10 and FIG. 11 , in a feasible embodiment, the body 10 can be composed of two halves 10a, 10b; each half 10a, 10b has a plane 16 respectively. It is shown that the ribbon 20 is arranged on the plane 16 of at least half body 10b. Specifically, the ribbon 20 can be arranged or printed on the plane 16 of the half body 10b, and the two half bodies 10a, 10b can be combined into an integral state to form the body 10 (or light guide strip). In principle, the width and length of the ribbon 20 can be varied; but will not exceed the width and length of the half plane 16 . In other words, the width of the ribbon 20 is less than the length of the diameter of the body 10 (or the width of the plane 16); the length of the ribbon 20 is not greater than (less than or equal to) the length of the body 10 (or the length of the plane 16) . In the adopted embodiment, the two halves 10a, 10b can be bonded by adhesive or high-frequency bonding; or the flat surfaces 16 of the two halves 10a, 10b can be bonded by heating.

Please refer to FIG. 12 , which depicts a derivative embodiment; it is a top view of the light guide strip, showing that the ribbon 20 is transformed into a character or pattern 20A.

Typically, the light guide strip structure with neon effect includes the following design considerations under the condition of providing a simplified structure:

1. This light guide strip structure is different from the known technology (for example, US 4,422,719, US6,169,836 B1, US7,433,565 B2), there is no structural organization of the body surface 12 provided with a coating protective layer or an overcoat; therefore, it can significantly reduce As in the old method, the luminous effect of the light guide strip is blurred or unclear.

2. This light guide strip structure also abandons the patents such as US 4,422,719, US6,169,836 B1, US7,433,565 B2, and spreads the structure of diffusing particles or scattering particles inside the core body; therefore, it can significantly reduce the generation of shadows or The diffraction fringe phenomenon further makes the selection or use of the light source type unrestricted; moreover, it reduces the manufacturing cost and complexity of the light guide structure.

The price of a 20cm-long light guide strip structure according to the present invention is about NT$10 or less; compared with the known technology, the manufacturing cost is obviously reduced, and it is attractive to the market.

3. In order to maintain or increase the reflection and refraction of light, a colored ribbon 20 is arranged inside the body 10; it can display a special visual effect of the light guide strip structure during the day; and it can be illuminated by the light source S After the structure of the light guide strip, it diffuses beautiful and clear light and neon effects in day and night respectively. Not only the internal structure of the light guide strip is rearranged and designed, but also has advantages that the known technology does not have.

4. After the internal structure of the light guide strip has been rearranged and designed, it is different from the old method with two planes that are very close to each other (that is, the inner surface of the jacket and the surface of the core body); it has significantly improved the reflection of light from the known two planes A situation where destructive interference or bright and dark bands are produced.

5. The sectional area ratio of the main body 10 and the ribbon 20 ranges from about 20:1 to 90:1. Therefore, the areas close to each other are reduced as much as possible, so that the destructive interference or light and dark bands produced by the reflected light of the main body 10 and the ribbon 20 are relatively minimized.

Therefore, the present invention provides an effective light guide strip structure with neon effect; its spatial configuration is different from the known technology, and it has functions that are not available in the old method, obviously showing considerable progress.
