1 is a block diagram of a stage lighting apparatus using an LED according to a preferred embodiment of the present invention, Figure 2 is a schematic diagram of the blocks shown in FIG.

1 and 2 respectively, the stage lighting apparatus using the LED according to the preferred embodiment of the present invention, the LED is controlled by the control unit 10 includes an LED for selectively emitting red, green, blue light respectively; The light source unit 20, the photosynthesis unit 30 for synthesizing the light of the light source unit 20 to emit light of a specific color, and the light of the photosynthesis unit 30 to condense the light into a straightness within a certain diameter A light output unit 50 including a light converging unit 40 to be switched, a diffractive lens provided with a light transmission pattern to diffuse light of the light converging unit 40, and emit light of various shapes, and the light output unit ( It comprises a rotary drive unit 60 for rotating the 50 to switch the pattern of the emitted light.

Hereinafter, the configuration and operation of the stage lighting apparatus using the LED according to a preferred embodiment of the present invention as described above in more detail.

First, the controller 10 executes a program set by a user, and supplies power to the LEDs R, G, and B constituting the light source unit 20 according to the brightness, color, and the like of the illumination.

That is, the controller 10 controls LEDs R, G, and B that emit red, green, and blue light, respectively, through voltage adjustment and frequency adjustment according to the programmed brightness and color.

The controller 10 may be configured to control the operation of the LEDs R, G, and B according to the number of bits of the sound signal transmitted to the surrounding sound or the signal line or the period of the base.

In this way, the light emitted from the LEDs R, G, and B controlled by the controller 10 is synthesized by the photosynthesis unit 30. The photosynthesis unit 30 emits light of a new color by synthesizing the monochromatic light emitted from the LEDs R, G, and B using a filter or a photosynthetic prism.

The light synthesized by the photosynthetic unit 30 may exhibit various colors, and the emitted light of the photosynthetic unit 30 is emitted at an angle of about 16 to 20 degrees. However, if the radiation angle is large in this way, it is not suitable for the stage lighting device that emits light of a specific pattern to produce an indoor atmosphere.

Therefore, the light emitted from the photosynthesis unit 30 is condensed through the light collecting unit 40 using the fresnel lens 41 and the light pipe 42. The Fresnel lens 41 collects light emitted from the photosynthesis unit 30 with a radiation angle of 16 to 20 degrees using a plurality of concentric circle patterns, and the light pipe 42 has a cross section of the Fresnel lens ( 41) the radiation portion 50 side is a smaller area than the side, and in the side portion is a structure in which light can be incident and emitted from each of the cross-sections on both sides without radiation. The light passing through the light pipe 42 is condensed into light having a radiation angle in the range of 1 to 4 degrees and is emitted.

At this time, the diameter of the collected light is to be about 8 to 10mm.

This is an emission angle similar to that when using a laser as a light source, which is advantageous for forming a specific light pattern.

Light emitted by adjusting the radiation angle through the Fresnel lens 41 and the light pipe 42 is radiated to the light of various patterns through the output unit 50 to be reflected on the stage of the concert hall and the walls of the room.

The output unit 50 includes a diffraction lens 51 provided with various figure patterns that can be arbitrarily implemented by a user, such as a star shape, a circle shape, and a polygonal shape, and the light incident on the diffraction lens 51 is diffracted and prevented. A square is radiated at an angle of 70 to 90 degrees, and a pattern of various colors is illuminated according to the pattern.

One or more diffractive lenses 51 may be provided, and different diffractive lenses 51 are provided in each of the plurality of diffractive lenses 51, and diffractive lenses positioned in the path of the light condensed and emitted from the condenser 40 are provided. The pattern of 51 is radiated.

Figure 3 is an embodiment configuration diagram of the output unit and the rotary drive unit in the stage lighting apparatus using the LED of the present invention.

Referring to FIG. 3, the output unit 50 is embedded in a body 52 of a disc shape and a body 52 of the same distance from the rotation shaft 53 protruding in one direction from the center of the body 52. The diffraction lens 51 is comprised.

The rotation driving unit 60 is configured to include a gear 62 for transmitting the driving force of the motor 61 to the rotation shaft 53 of the body 52.

The rotation driving unit 60 transmits the driving force of the motor 61 to the rotation shaft 53 of the body 52, and the diffraction lens 51 to which different patterns are applied to the path of the light emitted from the condenser 40. You can rotate to place different glyphs.

Therefore, the present invention can produce a variety of colors as well as the shape of the pattern as needed, it is possible to produce a variety of indoor and outdoor atmosphere.

Referring to FIG. 4, in the stage lighting apparatus using the LED according to another embodiment of the present invention, the color, brightness and color switching period of the emission light of the light source unit 20 according to the audio signal AUDIO in the basic configuration of FIG. 1. Control the rotational drive unit 60 according to the audio signal AUDIO to control the rotational speed of the diffractive lens 51 of the light output unit 50 to determine the replacement cycle of the shape of the light emission pattern. Can be configured.

In detail, the filter unit 100 receiving the audio signal AUDIO is classified according to the frequency band of the audio signal AUDIO. The filter unit 100 includes a band pass filter 101, a low pass filter 102, and a high pass filter 103, and filters and radiates an audio signal AUDIO corresponding to a band, respectively.

The reason for filtering the audio signal is that the frequency and the bit used are different depending on the type of music such as ballad, rock, dance and hip hop. To provide this automatically.

The signal that detects the audio signal AUDIO for each frequency band is an analog signal, and the signal detected for each frequency band by the analog / digital converter 110 is converted into a digital signal, which is sequentially stored in the memory 120. Stored as.

The average value of the digital signal stored in the memory 120 is determined by the average calculating unit 130 in a predetermined unit, and the average value is transmitted to the controller 10.

The reason for obtaining the average value is to ensure ease of control and to prevent excessively frequent color change and light emission pattern change.

The controller 10 receiving the average value emits a control signal corresponding to the input of the average value. Specifically, the controller 10 controls the light source unit 20 through pulse width modulation to determine and radiate the emission color of the light source unit 20. .

The controller 10 determines and outputs a rotation amount and a period of the motor 61 of the rotation driving unit 60 together with the control of the light source unit 20. This drives the motor 61 in synchronization with the frequency detected by the audio signal AUDIO to control the rotation amount and rotation speed of the diffractive lens 51 provided in the light output unit 50.

In addition, the average value is calculated by the average calculating unit 130 by detecting the magnitude of the signal, that is, the amplitude, at a time interval of about 10 times longer than the time interval of detecting the frequency from the signal stored in the memory 130. This amplitude represents the loudness of the sound, and the control unit 10 outputs a control signal for adjusting the brightness of the light source unit 20 as the sound of the corresponding frequency band is large and small.

That is, when the sound is loud, it may be controlled to emit light of the same color brighter.

This is to adjust the period of change of color and light emission pattern of stage lighting according to the frequency of music, and to adjust the brightness according to the volume. It relatively delays the change in color. On the contrary, the music with high volume and high frequency, such as dance music, produces brighter and more brilliant colors, and enables faster control of light emission patterns and color changes.

Referring to FIG. 5, in the stage lighting apparatus using the LED according to another embodiment of the present invention, the LEDs R, G, and B of the light source unit 20 are disposed to face each other at three angles at an angle of 90 degrees. The light of the LEDs R, G, and B is filtered through the reflection filter unit 31 and is configured to radiate to the fly's eye lens 32 as mixed light, which is light of a specific color.

The fly's eye lens 32 equalizes the brightness of the mixed light, and emits the light uniformed through the fly's eye lens 32, which is focused and emitted through the light collecting part 40.

The light collecting part 40 is composed of a lens member 41 and a driving member 42, so that the lens member 41 is rotated in accordance with the rotation of the driving member 42 to move within the range of the interval (d). The radiation angle of the mixed light emitted according to the position can be adjusted.

The light output unit 50 and the rotation driving unit 60 described above may be located at the exit side of the light collecting unit 40 to provide illumination having various patterns, and the light output unit 50 and the rotation driving unit ( Instead of using 60, the light of the light collecting part 40 may be used as the light as it is.
