Hereinafter, with reference to the accompanying drawings will be described in detail the decorative lighting device according to a preferred embodiment of the present invention.

1 is a view showing a lighting device according to an embodiment of the present invention.

Referring to the drawings, the lighting fixture has a light emitting unit 10, an optical fiber 17, a decorative bead 20 and a hanger 30.

The light emitting unit 10 includes a light source 11, a reflector 12, and a color filter wheel 13.

The light source 11 may be variously known. For example, an appropriate one may be applied depending on the use environment and purpose, such as an incandescent lamp, a discharge lamp, and a neon lamp.

The reflecting mirror 12 is installed at the rear of the light source 11 and focuses the light toward the rear of the light emitted from the light source 11 and emits it forward. The reflector 12 may be an ellipsoid, a parabolic mirror, and the like. In this case, the light source 11 is located at the focal position of the reflector 12.

A collimating lens for focusing (not shown) may be applied between the reflector 12 and the color filter wheel 13 to be described later.

The color filter wheel 13 is capable of selectively transmitting light of a specific color among the light emitted from the light source 11. For example, the color filter wheel 13 may be implemented by attaching a color filter of a predetermined color, for example, red, green, and blue, to each sector divided at a predetermined angle on a transparent disk. The color filter wheel 13 is installed to rotate the wheel shaft 13a by a driving source (not shown) such as a motor.

Of course, the color filter wheel 13 may be omitted, and some sectors of the color filter wheel 13 may be partially cut or processed so that the white light emitted from the light source 11 may be transmitted as it is. Can be.

A plurality of optical fibers 17 are arrayed in a bundle form, and one end of the optical fibers 17 is coupled to receive the light emitted from the light source 11 through its cross section 17a. Reference numeral 15 denotes an adapter that binds the bundle of optical fibers 17 and is detachably formed in the housing of the light emitting unit 10.

Preferably, the optical fiber 17 transmits most of the incident light through internal reflection, and a part of the optical fiber 17 may exit through the surface. The optical fiber 17 having such a structure is usually called a side light type optical fiber, and the interface between the core layer and the clad layer formed of a material having a lower refractive index than the core layer has a partially uneven portion. It is structured to be scattered to the outside. Examples of the optical fiber having such a structure are variously known, such as Korean Patent Publication No. 2002-0066493, Korean Patent Publication No. 1999-0014028, and detailed description thereof will be omitted.

The decorative beads 20 are coupled to the other end of each optical fiber 17 extending to a predetermined length. Reference numeral 30 is a hanger for properly supporting and spaced the bundles of the optical fibers 17 and fixing them to the object to be installed, for example, the ceiling of the building, and reference numeral 30a is a fixing hole. If the optical fiber 17 can be installed to be supported using the installation target facilities, the hanger 30 may be omitted or replaced with other facilities, of course.

Decorative ball 20 may be applied to a variety of structures, such as a polygonal shape or a sphere processed to have a plurality of surfaces. In addition, the decoration beads 20 may be formed of various materials, such as quartz, glass, transparent synthetic resin material as a material that can transmit light.

The coupling structure between the decorative beads 20 and the optical fibers 17 will be described in more detail with reference to FIG. 2. Elements having the same function as in the above-described drawings are denoted by the same reference numerals.

Referring to FIG. 2, the decorative ball 20 includes a liquid 24 and a reflector 25 filled in the inner space 23.

The decorative beads 20 are formed with an internal space 23 having a predetermined size.

The end portion 17b of the optical fiber 17 is installed to be inserted into the vicinity of the center of the inner space portion 23 through the opening 20a of the decorative ball 20. Reference numeral 21 is a sealing member that closes the opening 20a and couples the decorative beads 20 and the optical fibers 17 to each other. Various materials may be used as the material of the sealing member 21, and as an example, a transparent epoxy or silicone material may be applied.

The liquid 24 filled in the inner space 23 may be glycerin, paraffin oil, or other suspension having high scattering and refractive index.

The reflector 25 is formed to a minute size in the form of flakes and inserted into the liquid 24.

It is preferable that the reflector 25 is formed of thin flakes as small as possible so that the fluidity in the liquid 24 is high, and a small material is applied if the difference in specific gravity with the liquid to be applied is possible.

Various materials may be used as the material of the reflector 25, and as an example, aluminum, gold, tungsten, titanium, and molybdenum materials may be applied.

The decorative beads 20 form the decorative beads 20 to have the inner space 23, and then insert the optical fiber 17 through the opening 20a, and then open the liquid 24 and the reflector 25. What is necessary is just to produce it by inject | pouring into the inner space part 23 through the 20a, and sealing the opening 20a with the sealing material 21. Alternatively, after the optical fiber 17 is inserted into the molding apparatus, the decorative beads 20 are formed to form an opening and an inner space portion outside the optical fiber 17, and then the liquid 24 and the reflector 25 are formed in the inner space portion. It may be prepared by a method of injecting in (23) and sealing the opening 20a.

The luminaire having such a structure has light emitted from the light source 11 branched through the optical fiber 17 and then emitted from each of the decorative beads 20, and the emitted light is the liquid 24 of each decorative ball 20. And randomly scattered by the reflector 25. Therefore, since the central portion of the decorative beads 20 functions as a light emitting source, aesthetic color light efficiency can be obtained by scattering and emitting light independently from each other. In addition, since the restriction on the separation distance between the light emitting unit 10 and the decorative bead 20 is relaxed, the light emitting unit 10 can be installed at an easy position for repair, so that the repair work and the light source 11 can be easily replaced. By operating the color filter wheel 13, it provides an advantage that can selectively emit light of various colors.

On the other hand, according to another aspect of the present invention can be filled with a phosphor (not shown) containing a phosphorescent pigment in the interior space portion 23 of the decorative beads 20. In this case, the phosphor may be filled instead of the liquid 24 or included in the liquid.

The phosphorescent body may be a mixture of an appropriate mixture agent with the phosphorescent pigment. For example, when the transparent phosphor is to be applied, a mixture of a transparent resin, a phosphorescent pigment, a white pigment, a solvent, and other additives is applied. Examples of the phosphorescent pigments include at least one of aluminum oxide, calcium oxide, coral europium, strontium oxide, and boron oxide. Since the photoluminescent color is changed to green, blue, etc. according to the mixing ratio between the photoluminescent pigments described above, it may be appropriately mixed according to the desired photoluminescent color. Preferably, the weight ratio of the photoluminescent pigment is applied to about 10 percent. For example, resin 26 to 27%, photoluminescent pigment 5 to 6%, white pigment 6 to 8%, curing agent 0.3%, solvent 14 to 20%, sieving pigment 36 to 47% by mixing in the interior of the decorative beads 20 When injected into the space 23, it solidifies after a few minutes to obtain a solid photoluminescent body. In this case, the sealing member may be omitted. Alternatively, the phosphor can be filled in the liquid phase as a matter of course.

In addition, the photoluminescent material may include a reflector to fill the inner space.

As such, the structure in which the phosphor is filled in the inner space of the decorative beads has an advantage that light which is softly emitted to the phosphorescent pigment can be used even when extinguished.

Meanwhile, another embodiment of the structure in which the decorative light bulb 20 directly employs a semiconductor light emitting device having a much longer life and a smaller size than a general light bulb is illustrated in FIG. 3. Elements having the same function as in the above-described drawings are denoted by the same reference numerals.

Referring to the drawings, the lighting fixture has a light source control unit 50, a decorative ball 70 and a light emitting diode (80). Reference numeral 60 is a power supply line for supplying power from the light source controller 50 to the light emitting diode 80.

The light source controller 50 controls the driving of the light emitting diode (LED) 80. For example, the light source control unit 50 is configured to simultaneously turn on / off power supply to the light emitting diodes 80 of the whole or part set by manipulation of a switch. In this case, the light source control unit 50 is a power supply device (not shown) to which an inverter for converting a commercial AC power into a driving voltage for the light emitting diode 80 and a power supply device to the light emitting diodes 80 of the whole or part set. A switch unit (not shown) for turning on / off the power supply line 60 is applied. The inverter is omitted if the power supply voltage can be used as the voltage for the light emitting diode.

Unlike this, the light source controller 50 may be implemented to display the pattern or text selected by the user through selective driving of the light emitting diode 80. In this case, the light source controller 50 may selectively drive the light emitting diode 80 according to the input device (not shown) for selecting and setting a desired character or pattern and the setting information input from the input device. It may be provided with a drive module (not shown) and a power supply device (not shown) for supplying power to the drive module. The driving module may be configured to independently drive each power supply line according to the setting information of the input device, and the circuit configuration of such a driving module is variously known in the field of a display device using a light emitting diode, and thus a detailed description thereof will be omitted.
