Hereinafter, embodiments of a plastic optical fiber for lighting according to the present invention will be described with reference to the accompanying drawings. In this process, thicknesses of lines or sizes of components shown in the drawings may be exaggerated for clarity and convenience of description.

In addition, terms to be described later are terms defined in consideration of functions in the present invention and may vary according to the intention or custom of users or operators. Therefore, definitions of these terms should be made based on the contents throughout the present specification.

In addition, in describing the present invention, there are many prior art for materials such as core, clad, cover, reflective layer, metal wire, etc., and manufacturing methods using these materials are also well known. Since it can be manufactured in combination, a detailed description is omitted. Since the present invention is characterized by structural differences, only these structural features will be described.

1 is a block diagram showing a cross-section of a plastic optical fiber for lighting according to a first embodiment of the present invention.

Referring to FIG. 1, the plastic optical fiber for lighting according to the present invention includes a core 10 having a hollow 11 formed thereon, and a cladding 20 formed to surround the core 10 and containing a second light scattering agent. Include. Here, the clad 20 is preferably used as a material capable of transmitting 50% to 90% of light in a specific wavelength range and minimizing light loss.

When light generated using a laser, LED, etc. is incident on the core 10 and the hollow 11, the wavelength of light in the hollow 11 is transmitted toward the core 10, and the light of the core 10 is transmitted to the hollow 11 As it is transmitted, light is refracted at the interface of the hollow 11 to generate scattering. In this way, even if the clad 20 for transmitting a part of light is formed in the core 10 provided with the hollow 11, light is scattered due to the light transmission refractive index between the core 10 and the hollow 11, Light may be emitted to the side of the optical fiber through the clad 20 that transmits part of the light.

However, in order to more effectively improve the lateral emission of light, in the present invention, a second light scattering agent may be included in the clad 20. In addition, the core 10 may also contain a first light scattering agent. For convenience, the light scattering agent contained in the core 10 is referred to as a first light scattering agent, and the light scattering agent contained in the clad 20 is referred to as a second light scattering agent. The first light scattering agent and the second light scattering agent may be the same, but may be different light scattering agents.

As the light scattering agent, silicon that allows side light emission by diffusely reflecting light may be used. Zinc oxide may be used together with silicon as the light scattering agent. Zinc oxide can make light appear white, thus improving luminance. Therefore, by mixing silicon, which has an opaque property, which enables diffuse reflection of light, and zinc oxide, which improves brightness, through a light scattering agent, it is possible to achieve an improvement in brightness along with diffuse reflection of light.

Therefore, since it is scattered while passing through the hollow 11 and is scattered by the light scattering agent contained in the core 10 and the clad 20, the side divergence effect is improved.

In addition, the present invention may be configured to open the hollow 11 to maintain a general atmospheric state, or may be configured by being filled with an inert gas that scatters light and sealing both ends. When light is incident in the hollow 11 filled with an inert gas, a further improved light scattering effect may be obtained by light scattering of the inert gas.

2 is a block diagram showing a cross section of a plastic optical fiber for illumination according to a second embodiment of the present invention. As shown in Figure 2,

A transparent cover part 30 surrounding the outer surface of the clad 20 may be further formed, and the cover part 30 may be formed of a clad containing a third light scattering agent.

This, as the plastic optical fiber composed of the core 10 and the clad 20 can further form a transparent cover 30 as an outer shell, and can be utilized as a protective cover. In addition, the cover portion 30 may be formed of a second clad containing a third light scattering agent. By forming the cladding in two stages, the light emitted from the side can be evenly emitted by more effective light scattering. However, it is preferable to use a material that can effectively increase light transmittance and increase luminance.

In addition, the clad 20 or the cover 30 may be configured by further containing a fluorescent material together with a light scattering agent. Depending on the characteristics of the fluorescent material, the color of light can be changed, or it can be illuminated by a fluorescence reaction to external lighting.

3 is a block diagram showing a cross-section of a plastic optical fiber for lighting according to a third embodiment of the present invention. As shown in Figure 3, the plastic optical fiber for lighting according to another embodiment of the present invention,

Here, the reflective layer 50 may not be inserted as a separate layer and may be an interface between the surface of the metal wire and the core.

The light of the core 10 is reflected by the reflective layer 50, passes through the core 10, is transmitted to the clad 20, and is scattered by a change in refraction at each interface, so that side emission can be achieved. In particular, by inserting and installing the metal wire 50 inside, it is possible to maintain the foamed state of the optical fiber itself when it is formed into an arbitrary shape by the characteristics of the metal wire 40.

In general, plastic optical fibers can be bent in a round shape because the core 10 is made of a flexible material, but the bent state cannot be maintained without a peripheral support means. Therefore, in order to maintain the optical fiber-formed shape when installing by lighting using a conventional plastic optical fiber, a supporting means is absolutely necessary.

As shown in the third embodiment of FIG. 3, the plastic optical fiber including the metal wire 40 can maintain a formed shape without a support means due to the characteristics of the metal wire 40. Therefore, only light source devices such as laser LEDs can be fixedly installed, and plastic optical fibers can be maintained in a foamed state to implement decorative lighting.

It can be a configuration. The covering layer 70 integrated with the metal wire 40 may be the same material as the cover part 30 for the skin of FIG. 2 or 4, or may be a completely different material. However, the covering layer 70 should be a transparent or translucent material so that light scattered from the surface of the plastic optical fiber 60 can be smoothly transmitted to the outside. The main function of the metal wire 40 of FIG. 5 is to maintain the formed shape.

In addition, Figure 6 (A to (C) is to arrange the plastic optical fiber 60 and the metal wire 40 adjacent to each other, and surround them to configure the plastic coating layer 70 in various shapes such as a circle or oval or dumbbell shape. I can.

In addition, although not shown in the drawings, one or more optical fibers and one metal wire are arranged side by side, and wrapped with a transparent or translucent coating layer that transmits light by surrounding the plurality of optical fibers and the metal wire, and thus may be formed integrally.

In addition, a plurality of side-emitting optical fibers and a plurality of metal wires may be embedded in one coating layer to form an integrated plastic optical fiber cable.
