The optical fiber is an optical fiber in which a high refractive index glass is used in the central portion and a low refractive index glass is used in the outer portion, so that light passing through the center glass is totally reflected.

Total reflection refers to a phenomenon in which light incident on a small medium at an incident angle larger than a specific critical angle when the light propagates from an optically dense medium to a small medium is not refracted but is 100% reflected. To reduce the loss rate.

Such an optical fiber is made of synthetic resin, but it is made mainly of glass with good transparency. The structure usually has a double cylindrical shape in which a portion called a core is surrounded by a portion called a cladding.

In order to protect the outside from impact, the synthetic resin coating is applied once or twice. The total size of the core portion excluding the protective coating is from 100 to 100 탆 in diameter (1 탆 is 1/1000 mm), and the refractive index of the core portion is higher than the refractive index of the cladding, so that light can be focused on the core portion, .

Optical fibers having such a structure are widely used in electric, electronic, communication, medical, and optical fields due to their many advantages. In recent years, optical fibers capable of conducting light from one end to the other end in the longitudinal direction The use range of various decoration and illumination has been expanded.

Generally, fiber optic lighting devices are widely used for landscape lighting, decorative lighting, swimming pool lighting, and exhibition lighting. The optical fiber illumination device transmits light generated from one light source device generating light to an inlet and transmits light to the different optical fibers. The transmitted light is suitable for the purpose of use of the optical fiber, irradiation characteristics, length, etc. It is used as illumination. Such a fiber optic lighting device can be easily used for underwater lighting because it does not only transmit light except heat from a light source device but also has no danger of electric shock, and is widely used in places where normal lighting equipment can not be applied because of its high humidity. Used in difficult places.

In recent years, the use of such optical fibers has been widely used as landscape lighting. And so on are not only functions of illumination that illuminates the darkness, but also functions as a landscape lighting combined with landscaping and architecture to produce beauty, and additionally can maximize functions of lighting such as ease of maintenance and efficiency of light source Widely used.

At this time, a plurality of optical fibers are connected to each other in a bundle shape at one end and are arranged in the inner space of the rotary drum. The optical fibers are drawn out to the outer space of the rotary drum, The arrangement shape is arranged to form a specific decoration pattern on the landscape lighting panel.

According to this structure, since the optical fiber is drawn out from the inner space of the rotary drum to the outside and extended to each of the landscape lighting panels, the length of the optical fiber required becomes long and the optical fiber used for one of the landscape lights, Considering thousands of points, the length of the extended optical fiber increases sharply, resulting in unnecessary waste of the optical fiber and a significant increase in material cost. Further, since the optical fiber is bent several times in the process of drawing the optical fiber from the inside of the rotary drum to the landscape lighting panel outside the rotary drum, in this case, there is a problem that the efficiency of the illumination light is lowered as a whole due to the optical loss caused by the illumination light transmitted through the optical fiber there was. In addition, there is a problem that the operation of drawing out the optical fiber from the inner space of the rotary drum to the outside is complicated, so that the installation work takes a long time and maintenance work such as replacement or maintenance of the optical fiber is also inconvenient.

3 and 4, the supporting guide module 600 includes a moving block 611 having a coupling hole 611 formed at its center so that one end 410 of the optical fiber 400 coupled in a bundle shape can be inserted and coupled, A guide protrusion 620 formed on one side of the movable block 610 so as to protrude outwardly and a guide block 620 slidably moved in a direction in which the movable block 610 moves toward or away from the rotary drum 200, And a support member 630 formed in a hollow pipe shape. A guide groove 631 for guiding the movement path of the guide protrusion 620 which moves integrally with the moving block 610 is formed on one side of the support member 630. On the inner side surface of the guide groove 631, The concavity and convexity groove 632 can be formed so that the concave groove 620 can be engaged and moved step by step.

That is, one end 410 of the optical fiber 400 is coupled in a bundle shape to be inserted into the coupling hole 611 of the moving block 610, and the moving block 610 is movably coupled to the supporting member 630 do. At this time, the guide protrusion 620 coupled to the moving block 610 is guided by the guide groove 631 of the support member 630, and is moved step by step by the protrusion groove 632.

Particularly, even if the length of the optical fiber 400 is not precisely cut due to the tolerance or the length of the required optical fiber 400 is changed due to the installation problem, the end 410 of the optical fiber 400 It is possible to more conveniently perform the installation work.

FIG. 5 is a perspective view schematically showing the configuration of an optical fiber illumination light generating device according to another embodiment of the present invention, FIG. 6 schematically shows the configuration of a light guide member used in the optical fiber illumination light generating device shown in FIG. And FIG. 7 is a cross-sectional view schematically showing the internal structure of the light guide member shown in FIG.

As shown in FIG. 5, the optical fiber illumination light generator according to another embodiment of the present invention may be configured such that a plurality of optical fibers 400 are arranged outside the rotary drum 200 in units of bundles.

That is, as described above, the optical fiber 400 having the bundle unit bundle 410 may be disposed at a plurality of positions along the circumference of the rotary drum 200, And may be formed corresponding to the illumination panel 10. For example, as shown in FIG. 5, when four of the landscape lighting panels 10 are present in the shape of a quadrangular prism, four optical fibers 400 are disposed at positions corresponding to the respective landscape lighting panels 10 .

When the optical fibers 400 are arranged at positions corresponding to the respective landscape lighting panels 10 in bundle units, the bundles of the optical fibers 400 are bundled from the end 410 of the optical fiber 400 to the landscape lighting panel 10, The waste of the optical fiber 400 can be minimized and the material cost can be further reduced.

In this case, a plurality of illumination lamps 100 may be mounted to irradiate the optical fiber bundles disposed at the respective positions, respectively. Alternatively, a plurality of illumination lamps 100 may be mounted on the optical fiber bundle, And a light guide member 700 for branching the optical fiber bundle and transmitting the branched optical fiber bundle to each optical fiber bundle.

The illumination light of the illumination lamp 100 is directed toward the outer circumferential surface of the rotary drum 200 so as to pass through the color filter 210 in the inner space of the rotary drum 200. In other words, The light guiding member 700 can be mounted so that it can be intensively guided and transmitted.

Such a light guide member 700 is applicable even when the optical fiber bundle is not disposed at a plurality of positions. For example, in the case where one illumination lamp 100 and one optical fiber bundle are present as shown in FIGS. 1 and 2, the light guide member 700 is not shown, but the illumination light of the illumination lamp 100 And can be formed so as to be able to concentrate to one optical fiber bundle side.

However, the efficiency of the light guide member 700 increases when a plurality of optical fiber bundles exist, rather than when one optical fiber bundle exists. 5, when the optical fiber bundle is provided, the light guide member 700 may be configured to branch the illumination light generated from one illumination lamp 100 and transmit the branched illumination light to the optical fiber bundle side, It is not necessary to provide a plurality of illumination lamps 100, which simplifies the structure.

6 and 7, the light guide member 700 includes a main light guide 710 for receiving and transmitting the illumination light of the illumination lamp 100, and an illumination light for transmitting the illumination light through the main light guide 710 And a sub light guide 720 branched from the main light guide 710 to be branched so as to be able to transmit the bundle of optical fibers 400 arranged at a plurality of positions, respectively. The main light guide 710 and the sub light guide 720 may be formed in a hollow pipe shape and a total reflection layer 730 may be formed on the inner side of the main light guide 710 and the sub light guide 720 so that the illumination light can be totally reflected and transmitted.

When a bundle of a plurality of optical fibers 400 is provided corresponding to each of the landscape lighting panels 10 and the illumination light is transmitted to the bundle of the optical fibers 400 through the optical guide member 700, The colors of the color filters 210 of the rotary drum 200 corresponding to the plurality of sub light guides 720 branched from the sub light guides 720 may be different from each other so that the illumination light of different colors may be transmitted to the respective optical fibers 400, In each of the landscape lighting panels 10, a pattern M of different colors can be formed, so that the lighting color expression of the landscape lighting can be realized in a more various ways.

Although not shown, a separate open / close flip (not shown) may be mounted on the sub-light guide 720 to block or unblock the illumination light from being externally emitted, The illumination light is not transmitted to the optical fiber 400 corresponding to the display unit 720, thereby blocking illumination light transmission to the specific landscape lighting panel 10 according to the user's need, have.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
