Generally, a fiber refers to a fiber produced so that the refractive index of light is high in the inside and low in the outside so that total optical phenomenon occurs inside the fiber.

Because this optical phenomenon is used, it is also called optical fiber. In order to reduce light loss when transmitting light, highly transparent material is required, and high-purity quartz or a polymer material having excellent optical properties is used.

Recently, it has been widely used as an advertising means by allowing various colors to be displayed on an optical fiber. When an optical fiber is densely packed and fixed in the form of a letter or figure, and a light of a specific color is projected on the opposite end, the light is transmitted as if it is a neon effect.

Because of the nature of optical fiber, the transmission of light is quick and bright, and various color animation can be produced. Various types of advertisement expressions can be expressed very precisely according to the thickness.

Due to the characteristics of utilizing light, it exhibits its function at night or in the dark. For this reason, optical fiber yarn is manufactured and weaving of clothes and clothes is greatly improved. Therefore, it is possible to utilize fiber-optic yarn to weave clothes and other fabrics for rescue workers, military or leisure activities. Light emission using an optical fiber is transmitted to an optical fiber when light is emitted from the light source, and light emission is performed on the cut surface.

On the other hand, LEDs of red, green, and blue (hereinafter, referred to as "RGB"), which are three primary colors of light, are used as light sources in order to display various colors through an optical fiber. However, in the prior art, since the afterglow of the previous color is left at the moment when the color is changed, there is a problem that unspecific colors are displayed by mixing with the next color. In addition, in the case of a conventional lighting apparatus using an optical fiber, the configuration is more than a certain level, which results in a problem of a reduction in manufacturing efficiency and an increase in manufacturing cost as the configuration increases.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to let you know. Wherein like reference numerals refer to like elements throughout.

As a color variable type integrated optical fiber illuminator (hereinafter, referred to as 'illuminator') according to one preferred embodiment of the present invention, by forming a part of the components integrally, it is possible to increase manufacturing efficiency by reducing the number of parts, You can. Such an illumination device includes an RGB light source unit including red, green, and blue LEDs, and a control unit, and will be described in detail below with reference to various embodiments.

1 is a cross-sectional view showing a lighting apparatus according to a first embodiment of the present invention.

1, the lighting apparatus according to the first embodiment of the present invention includes a coupling member 110 to which the RGB light source unit 100 is coupled at one side, a coupling member 110 at the inside of the coupling member 110, And a plurality of optical fibers 131 coupled to the other side of the coupling member 110 so as to be in contact with the other side of the afterglow absorbing member 120. The residual light absorbing member 120 is formed integrally with the RGB light source unit 100, (Not shown).

The RGB light source unit 100 is a substrate in which three color LEDs 101 constituting the three primary colors of red (R), green (G) and blue (B) Accordingly, the three-color LEDs 101 are turned on singly or in parallel to emit single or mixed colors.

The coupling member 110 may be formed in a cylindrical shape having openings at both ends and having a hollow shape, but may also be formed to have various shapes such as a triangular shape, a square shape, and a pentagon shape. The RGB light source unit 100 is coupled to one end opening of the coupling member 110. When the RGB light source unit and the socket are screwed to the coupling member as in the second embodiment described later, the hollow of the coupling member may have a circular shape such as a circular shape or a quadrangular shape. .

In the present embodiment, the RGB light source unit 100 and the socket 130 are hooked to the coupling member 110, respectively. A first hooking hook 111 is formed on one side of the coupling member 110 and a second hooking hook 102 is formed on the RGB light source unit 100 to hook the hooking hook 111 with the first hooking hook 111 . The third engaging hook 112 is formed on the other side of the engaging member 110 and the fourth engaging hook 132 is formed on the socket 130 to engage with the third engaging hook 112 in the same manner. Here, since the RGB light source unit 100 and the socket 130 are made of a plastic material whose appearance is more flexible than a certain level, hook coupling as described above becomes possible.

The afterglow absorbing member 120 is formed of transparent glass or synthetic resin, and the surface is etched to improve the light dispersing ability. When the afterglow absorbing member 120 is specifically divided, it becomes a binder ball, a glass ball, a plastic ball, and a crystal ball. Since the afterglow absorbing member 120 is formed integrally with the engaging member 110 on the inner side of the engaging member 110, the material of the engaging member 110 is also the same as that of the afterglow absorbing member 120 . In addition, as described above, since the coupling member 110 is made of a transparent material, the light emitted from the RGB light source unit 100 may pass through the coupling member 110 and be diverted to the outside. In order to prevent this, it is preferable that a coating or a vinyl film 150 is additionally provided on the outer surface of the coupling member 110 to limit external emission of light transmitted through the coupling member 110.

In this embodiment, the afterglow absorbing member 120 has a convex shape on both sides, and is convexly formed hemispherically from the inner surface of the engaging member 110. In other words, the afterglow absorbing member 120 can be said to have a substantially hemispherical structure at both ends of the cylindrical shape.

First, the RGB light source unit 100 is hooked to one side of the coupling member 110, and a controller (not shown) and a power supply unit (not shown) are connected to the RGB light source unit 100. At this time, the RGB light source unit 100 is brought into close contact with one side of the afterglow absorbing member 120 as much as possible.

The control unit controls the lighting order and time of the LED 101 of the RGB light source unit 100.

Then, the socket 130 for bundling the bundles of optical fibers 131 is hooked to the other side of the coupling member 110 and is closely adhered to the afterglow absorbing member 120 as much as possible.

Then, the LED of the RGB light source unit 100 is turned on according to a signal of the control unit. For example, after the red LED is turned on and then blinks, the afterglow is absorbed by the afterglow absorbing member 120 and then disappears.

Since the afterglow absorbing process is performed in a very short time, it can be extinguished before it is transmitted to the optical fiber 131, and no color disturbance due to afterglow is found outside. Accordingly, color conversion of the optical fiber 131 can be performed immediately, and a clear and accurate color representation is possible.

That is, threads are formed on both inner circumferential surfaces of the coupling member 210 and on the outer periphery of the RGB light source 200 and the socket 230, respectively. As compared with the hook-and-hook structure of the first embodiment, the coupling structure of the RGB light source unit 200 and the socket 230 with respect to the coupling member 210 can be minimized to improve the coupling stability. In addition, compared to the first embodiment, the RGB light source unit 200 and the optical fiber 231 can be firmly held on both sides of the afterglow absorbing member 210, thereby enhancing the light emission efficiency.
