[Mode for Invention]
Hereinafter, preferred embodiments in accordance with the present invention will be described with reference to the accompanying drawings. The preferred embodiments are provided so that those skilled in the art can sufficiently understand the present invention, but can be modified in various forms and the scope of the present invention is not limited to the preferred embodiments.
Fig. 1 is cross-sectional view depicting a general connection structure for projecting light to a plurality of optical fibers.
According to the method of Fig. 1 the optical fiber bundle 10 is formed by tying a plurality of optical fibers 11 using a clamp 12 of a metal material, for example. Then, the optical fiber bundle 10 and the light emitting diode 30 are inserted into both ends of the connector 20 formed of a tube in a cylindrical shape. Here, the connector 20 is made of metal or synthetic resin such as plastic.
In the above structure, the light emitted from the light emitting diode 30 is projected directly through an end
surface of the optical fiber 11 or reflected from an inner wall of the connector 20 and then projected through the end surface of the optical fiber 11. However, in case of metal or synthetic resin, it cannot effectively reflect the light. The light reaching the inner wall of the connector 20 may be absorbed or diffused. The light absorbed or diffused in the connector 20 is not projected to the optical fiber 11 but disappears .
To solve the above problem, the light emitting diode 30 and the optical fiber bundle 10 may be arranged adjacent to each other and, as a result, it is possible to minimize the amount of the light disappearing in the inner wall of the connector 20.
However, the light amount projected to the optical ■ fiber has a significant difference according to the incidence angle. Light having an incidence angle of 75° to 105 ° against the end surface is effectively projected and transmitted in the optical fiber. Moreover, the light emitting diode 30 does not emit light at all angles. The angle of the light emitted from the light emitting diode 30 has an angle of 30° up and down based on an approximately center-line. Accordingly, if the optical fiber bundle 10 and the light emitting diode 30 are arranged adjacent to each other, the light is effectively transmitted to the optical fibers 11 arranged adjacent to the central portion
of the light emitting diode 30, however, the light is not well transmitted to the optical fibers 11 arranged adjacent to the outer circumference of the light emitting diode 30.
To solve the above problem, according to a preferred embodiment of the present invention, a light reflecting layer is formed on the inner wall of the connector 20 while keeping the intervals between the optical fiber bundle 10 and the light emitting diode 30. That is, the connector 20 in accordance with the present invention comprises a light reflecting layer established on the inner wall thereof.
The following various methods can be applied to form the light reflecting layer on the inner wall of the connector 20:
1. In a case where the connector 20 is made of a metal material, the inner wall of the connector 20 is polished using a diamond turning machine, for example;
2. In a case where the connector 20 is made of aluminum, a uniform oxide layer is formed on the inner wall of the connector 20 using an anodization process, for example;
3. In a case where the connector 20 is made of synthetic resin such as plastic, a metal layer having excellent reflectance such as aluminum and chrome, for example, is established on the inner wall of the connector 20. Here, in the formation of the metal layer, it is
possible to use a general plating process or a deposition process such as evaporation or sputtering; and
4. In a case where the connector 20 is made of synthetic resin such as plastic, a light reflecting paint having excellent reflectance such as aluminum paint and silver spray paint, for example, is coated on the inner wall of the connector 20.
Of course, the present is not limited to the above- described methods, but can adopt any method for forming the light reflecting layer on the inner wall of the connector 20
In the above-described embodiment of the present invention, the light reflecting layer is established on the inner wall of the connector 20 for optically connecting the optical fiber bundle 10 with the light emitting diode 30. Accordingly, the light emitted from the light emitting diode 30 is not absorbed or diffused in the inner wall of the connector 20 but reflected by the light reflecting layer to be introduced to the optical fiber 11, thus sharply increasing the light transmission efficiency from the light emitting diode 30 to the optical fiber 11.
Meanwhile, Figs. 2 and 3 depict a connection structure between the optical fiber bundle 10 and the light emitting diode 30 in accordance with another embodiment of the present invention. Fig. 2 shows a cross-sectional structure of a connection structure in accordance with the present
embodiment and Fig. 3 is a perspective view depicting an end section of the optical fiber bundle opposite to the light emitting diode.
As described in detail in Fig. 3, the end surface of the optical fiber bundle 10 opposite to the light emitting diode 30 is processed to be curved in a shape corresponding to a light emitting surface of the light emitting diode 30. In more detail, the end of the central portion of the optical fiber bundle 10 is positioned more adjacent to the inside than that of the outer circumference of the optical fiber bundle 10 and, in view of the end surfaces of the respective optical fibers 11 constituting the optical fiber bundle 10, the optical fibers positioned on the outer circumference have lengths in the long-axis greater than those positioned on the central portion, thus having end surfaces of an oval shape. Such a curving process can be readily realized by grinding the end surface of the optical fiber bundle 10 using a grinding apparatus or by a method in which a metal rod having the same shape as the light emitting surface of the light emitting diode 30 is heated at a predetermined temperature and then placed adjacent to the optical fiber bundle 10.
In the present embodiment, the respective optical fibers 11 constituting the optical fiber bundle 10 are arranged in such a manner that the end surface thereof are
parallel to the light emitting surface of the light emitting diode 30. Accordingly, even in the case where the light emitting diode 30 and the optical fiber bundle 10 are arranged adjacent to each other, the end surfaces of the respective optical fibers 11 constituting the optical fiber bundle 10 maintain an angle of approximately 90° against the light emitted from the light emitting diode 30, which facilitates the projection of the light to the optical fibers 11 and further makes it possible to arrange the light emitting diode 30 and the optical fiber bundle 10 adjacent to each other. Moreover, if the light emitting diode 30 and the optical fiber bundle 10 are arranged adjacent to each other, the amount of the light that comes in contact with the inner wall of the connector 20 is remarkably reduced, thus increasing the light transmission efficiency from the light emitting diode 30 to the optical fiber bundle 10.
As above, preferred embodiments in accordance with the present invention have been described and illustrated, however, the present invention is not limited thereto, rather, it should be understood that various modifications and variations of the present invention can be made thereto by those skilled in the art without departing from the spirit and the technical scope of the present invention as defined by the appended claims. For example, in the above-described first and second
embodiments, the description has been made about the structure in which the light reflecting layer is formed on the inner wall of the connector 20 and then the end surface of the optical fiber bundle 10 is processed to be curved. However, if the end surface of the optical fiber bundle 10 is processed to be curved while forming the light reflecting layer on the inner wall of the connector 20 by mixing these embodiments, it is possible to increase the light transmission efficiency from the light emitting diode 30 to the optical fiber bundle 10 more and more.
[industrial Applicability)
As is apparent from the above explanations, according to the present invention, it is possible to realize a connection structure between a light emitting diode and an optical fiber bundle that can effectively project the light emitted from the light source such as a light emitting diode to the respective optical fibers of the optical fiber bundle. Moreover, according to the present invention, it is possible to embody a connector that can provide an efficient connection between the light emitting diode and the optical fiber bundle .
