As shown in the figures, the lighting apparatus of the present invention includes a main body 10 in the form of a pillar, which can stand on the floor such that special devices for providing special effects can be installed therein.

As shown in Fig. 3, the main body 10 includes a pair of adjusting rods 12 of which height can be adjusted. Adjustment levers 13 are installed to the adjusting rods 12, respectively, to adjust the height of the adjusting rods 12. In addition, a pair of coupling levers 14 are installed to the adjusting rods 12 such that light supports 34 to be described later can be coupled thereto. Each of the coupling levers 14 is installed such that it can be fastened to and moved vertically along the adjusting rod 12, and the coupling level 14 is formed with a coupling protrusion 15 at one side thereof such that the light support 34 can be fitted thereto. Furthermore, a pair of installation levers 16 are provided to the adjusting rods 12 such that it can be fastened to a laser emitting device 62, which will be described later, for vertical movement of the laser emitting device.

Further, a controller 20 for recognizing an external sound signal and transmitting a corresponding input signal to control the operation of the lighting apparatus according to the present invention is installed in the main body 10. Preferably, the controller 20 includes a microphone 22 for recognizing an external sound signal.

A lighting unit 30 for providing illumination is installed to the coupling protrusion 15 formed on the coupling lever 14 of the adjusting rod 12. The lighting unit 30 can be pivoted on the coupling protrusion 15. At this time, a driving means 15' for receiving a signal from the controller 20 to control the pivot motion of the lighting unit is provided in the coupling protrusion 15, and a rotatable driving shaft 32 is connected to the driving means 15' (see Fig. 3). Thus, the lighting unit 30 can be coupled to and pivoted about the driving shaft 32.

The lighting unit 30 includes a light support 34 with predetermined length and section which can be pivotally installed to the coupling protrusion, and a plurality of lights 36 which are installed on the light support 34 and blink in accordance with a signal input from the controller 20. The lighting unit 30 is a part for generating light.

A reflection plate unit 40 is installed to the rear of the lighting unit 30 to reflect light generated from the lights 36. The reflection plate unit 40 is shaped as a panel and includes a reflection plate support 41 which is fixed to a rear side of the light support at a front lower end thereof and is formed with a light reflector at a front surface thereof. At an upper side of the reflection plate support 41 is provided a guide 43 that is bent from the reflection plate support 41 at a predetermined angle and formed with a guide hole 42 through which a support rod 52 to be described later can be moved. At an upper end of the guide 43 is formed a first fixing plate 44 that is bent from the guide. The first fixing plate 44 has a length corresponding to the height of a reflection plate 50 to be described later. Further, a coupling plate 45 bent at a predetermined angle is formed at a distal end of the first fixing plate. Furthermore, the coupling plate 45 is formed with a coupling hole 46 into which a front protrusion of the reflection plate 50 is inserted.

As shown in Fig. 5, a second fixing plate 47 is installed to a lower end of the guide 43. That is, the first and second fixing plates 44 and 47 are installed to the upper and lower ends, respectively, with respect to the guide hole 42. The second fixing plate 47 is manufactured with a relatively shorter length to support a rear end of the reflection plate 50. First and second support protrusions 48 and 49 are formed at a lower side of the rear end of the first fixing plate 44 and an upper side of the second fixing plate 47, respectively. The first and second support protrusions 48 and 49 are installed to opposite sides with respect to the guide hole 42 such that the reflection plate 50 can be vertically moved in an asymmetric way.

The reflection plate 50 for reflecting the light emitted from the lighting unit is installed above the reflection plate support 41. The reflection plate 50 has a front surface made of a reflective material capable of reflecting light and includes a front protrusion 51 which is formed at its front end and inserted in the coupling hole 46 and a support rod 52 which is formed at its rear end and inserted in the guide hole 42. The front protrusion 51 and support rod 52 of the reflection plate 50 are respectively inserted in the coupling hole 46 and the guide hole 42. Preferably, the front end of the reflection plate 50 is connected to the first fixing plate 44 by means of springs 53 at both sides thereof with respect to the front protrusion 51. The spring 53 is a part for allowing the reflection plate 50 to be supported at a horizontal state when the plate is not moved.

A driving unit 54 is installed to the rear side of the reflection plate support 41 to move the support rod 52. The driving unit 54 includes a motor 56 for providing a rotating motion in response to a signal received from the controller 20, and a cam 58 which is coupled to a rotary shaft of the motor 56 and brought into contact with the support rod 52 to convert a rotating motion from the motor 56 into a vertical motion of the support rod 52. The driving unit 54 moves the reflection plate 50 by means of the support rod 52 such that reflective light may change its lighting direction in various angles.

As described above, the reflection plate support 41, the reflection plate 50 and the driving unit 54 are assembled into the reflection plate unit 40 that reflects light from the lights 36 in various directions.

Meanwhile, as shown in Fig. 3, a laser emitting device 62 for emitting laser is installed to the pair of installation levers 16 such that it can be pivoted on the rotary shaft 63. Further, a reflection plate assembly 64, which has the same configuration as the reflection plate unit 40 and reflects laser emitted from the laser emitting device 62, is installed to the rear of the laser emitting device 62. Preferably, a soap bubble injecting device 65 for injecting soap bubbles in response to an input signal from the controller 20 is installed within the main body 10.

A display unit 60 is provided at the front side of the main body 10 by causing a front surface of the main body 10 to be slightly depressed inward by a predetermined depth. The display unit includes a plurality of light emitting devices that blink in response to an input signal from the controller 20. Preferably, the light emitting device is a light emitting diode (LED).

A fog injecting device 68 for injecting fog in response to an input signal from the controller 20 is preferably installed to a lower end of the display unit 66. Furthermore, a cash receiving device 70 for detecting an amount of money inserted, determining a service time accordingly and displaying the determined service time may be installed in the main body 10.

Hereinafter, the operation of the lighting apparatus according to the present invention will be described in detail based on its operating sequence. First, a user who wishes to install the lighting apparatus of the present invention places the lighting apparatus at a desired position. Then, the user unfastens the adjustment lever 13 to adjust the height of the adjusting rod 12 and then fastens the adjustment lever 13 to fix the rod at a desired height. At this time, the adjusting rod 12 is preferably adjusted to be brought into contact with the ceiling such that the lighting apparatus of the present invention can be supported on the ceiling. Thereafter, the coupling lever 14 is unfastened to set the lighting unit 30 at a desired height and at a desired angle, and then is fastened to fix the lighting unit 30 at the desired height and angle. The light support 34 is pivoted to set the lights in a desired direction.

Next, the laser emitting device 62 is set to a desired height through the installation lever 16 and then pivoted about the rotary shaft 63. Finally, the installation process is completed.

After the installation has been completed, the lighting apparatus of the present invention will be operated.

If music is played in the room, its sound is transferred to the controller 20 through the microphone 22 installed in the controller 20. The controller 20 classifies the input sound and then transmits the classified signals to respective devices. Accordingly, the lights 36 emit light, and the reflection plate 50 moves its rear end vertically with respect to its front end. Furthermore, in a case where the light support 34 is pivoted by means of the driving means 15', it is pivoted in response to the input signal while the lighting apparatus is operating.

As shown in Fig. 8, the controller 20 first detects an external sound through the microphone 22 (S lO). At this time, it is preferred that an external sound over a predetermined volume be selectively input. That is, any sound which does not influence on the played music and surrounding noise are preferably removed. Then, the controller 20 detects the rhythm and kind of a sound source of the detected external sound (S20). Of course, although the preferred embodiment of the present invention has been illustrated based on only the rhythm and kind of a music source, other information on melody, genre or the like may be further checked in addition to the rhythm and kind of the sound source. At this time, the kind of sound source may be the kind of musical instrument in a case where the music is played by the musical instrument, or it may be a voice of a singer or a handclap sound.

Further, the controller 20 drives the driving means 15' and the driving unit 54 in accordance with the checked rhythm and kind of the sound source (S30). The controller 20 allows the above steps S lO to S30 to be repeated at a predetermined time interval in order to control the operations of the driving means 15' and the driving unit 54 at the predetermined time interval.

As described above, the controller 20 drives the driving means 15' and the driving unit 54, and simultaneously, the laser emitting device 62 emits laser which in turn is reflected on the moving reflection plate 50 and then travels in unspecified directions. In addition, the LEDs installed to the display unit 66 blink to display an image, and fog or soap bubbles may also be injected.

The sequential operations change their operating patterns according to the external sound. For example, in a case where the lighting apparatus of the present invention is operated according to fast dance music, the lights 36 blink fast in accordance with the fast rhythm of music. In addition, the reflection plate 50 for reflecting light from the lights 36 is also moved in accordance with the fast rhythm of music, and the reflection plate assembly 64 is also moved in accordance with the fast rhythm of music. Therefore, the direction in which the laser and light from the lights 36 are reflected is changed in accordance with the rhythm of music, so that an atmosphere suitable for the dance music can be provided.

Furthermore, an image suitable for the fast dance music is displayed on the display unit 66. For example, a motion of a person dancing a fast night dance may be expressed on the display unit 66. At this time, the motion of the reflection plate 50 will be described in detail. As shown in Fig. 7, the motor 56 installed to the rear of the reflection plate support 41 is rotated in response to a signal input from the controller 20. If the motor 56 rotates, the cm 58 installed to the rotating shaft of the motor 56 is rotated accordingly. Then, the cam 58 having an elliptical profile causes the support rod 52 brought into contact with the cam 58 to move in a vertical direction. The support rod 52 moves vertically along the guide hole 42, and thus, the rear end of the reflection plate 50 is also moved in a vertical direction.

If the reflection plate 50 is moved upward, a portion on the upper surface of the reflection plate 50 is pressed by the first support protrusion 48. Thus, the reflection plate is moved upward while a side of the plate opposite to the first support protrusion 48 is lifted On the other hand, if the reflection plate moves downward, a portion on the lower surface of the reflection plate 50 is pressed by the second support protrusion 49. Thus, the reflection plate 50 is moved downward while a side of the plate opposite to the first support protrusion 48 is lifted. That is, while the rear end of the reflection plate 50 is moved in a vertical direction, a side of the reflection plate 50 near the second support protrusion 49 is moved up. Thus, the direction of light reflected by the plate is changed at various angles.

The scope of the present invention is not limited to the aforementioned embodiment but defined by the appended claims. Thus, it is apparent to those skilled in the art that various changes and modifications can be made thereto within the scope of the invention defined by the claims. [Mode for Invention]

The present invention may be modified in various ways in addition to the aforementioned embodiments. For example, although it has been described that the display unit 66 is preferably provided to the front side of the main body 10, its position may be variously changed according to an installation position or usage purpose of the lighting apparatus of the present invention. That is, the display unit 66 may be folded from the main body such that the lighting apparatus of the present invention can be spread in use as a large screen. In addition, although it has been illustrated in the preferred embodiment of the present invention that the controller 20 detects an external sound and immediately transmits a control signal, the controller 20 can store a specified table and then compare the kind of an external sound with the table to control lights according to the method specified in the table. Furthermore, the controller 20 can also control a part of the lights in response to some elements of the external sound and controls the other lights according to the other elements.

Moreover, each component of the present invention can be implemented in a separate manner. For example, only the lighting unit may be provided without installing the reflection plate unit. In addition, the lighting unit may not be fixed to the main body but to the wall or other equipment. [Industrial Applicability]

According to the present invention so configured, since the lighting effects are changed according to the rhythm of music, a user can enjoy an entertainment joyfully.
