Referring to the operation of the present invention configured as described above is as follows.

The present invention is to adjust the brightness and color of the lighting stand in accordance with the music of the audio system, the lighting stand is provided with a color conversion means and brightness control means. As the color conversion means, a color filter 180 and a clip bar 182 for selecting and transferring (rotating) the color filter 180 for each color are provided, and the clip bar 182 is a step motor 181. By step by step) to adjust the color filter 180 of the desired color is located on the front of the lighting lamp (170).

On the other hand, the database 140 for the brightness control and the color control of the lighting is pre-configured for each music parameter by many experiments and various applications so as to induce human emotion according to audio, that is, music.

In this way, the emotional database 140 is built in advance for the emotional lighting, and the controller 120 controls the emotional database 140 based on the mode selection of the keyboard 130 and the music parameter of the music parameter detector 110. The brightness control and color control data are read and configured to control the brightness control unit 150 and the filter control unit 160.

The music parameter detector 110 detects a component of music input through the FFT analyzer 112, the pitch detector 113, and the bandpass filter 114, and then determines the music parameter table 115. The parameter is found and the music parameter is input to the controller 120. Accordingly, the control unit 120 finds the corresponding control data in the database 140 based on the music parameter.

Therefore, in the present invention, the CD player 10 is installed directly on the audio stand as shown in FIG. 6, the emotional lighting control device 100 is installed inside the speaker 190, and the mode selection switch 130.

According to the present invention, after the user turns on the power, the CD player 10 is operated or an external audio signal is input and the emotional lighting mode is selected. Mode selection distinguishes manual mode from automatic mode. In the manual mode, various types of modes are set as shown in each mode selection key of FIG. 5, and the lighting control program, which is experimentally obtained according to the type of music for each mode, is operated to detect the parameters of the music actually input. Controlled by a predetermined lighting program.

In addition, the automatic mode detects a parameter by the music actually input and finds lighting control data in the database 140 based on the parameter to control brightness and color.

In the automatic mode, as illustrated in FIG. 3, the input audio signal is analyzed to detect music parameters, and the corresponding brightness and color control data are found in the database 140 based on the parameters to control lighting.

The brightness control may adjust the voltage of the lighting lamp 170, or control the current to the required brightness, the color control controls the step motor 181 through the filter control unit 160 to control the color filter 180 In order to select, the position information of the filter which knows which position the filter of the color to be adjusted is obtained, and the step motor 181 is operated to stop when the corresponding filter is positioned in front of the illumination lamp 170. Accordingly, the filter of the desired color is positioned in front of the lighting lamp 170 to adjust the color to be illuminated.

These movements are controlled to induce the human emotion most naturally and to increase the effect according to the music or the mode-specific program selected by the manual mode, which is naturally controlled by using the database by the music parameter.

On the other hand, in the embodiment of the present invention to adjust the stand using a general lighting lamp to the music, the color filter and the click bar, step motor, etc. are installed in the gearlan for controlling the color filter, but is limited to this Instead, the lighting color can be changed freely by using various color lighting lamps or color display LEDs. In such a case, a general lighting lamp and a color LED can be provided together and can be selected and used for a necessary use. That is, the general stand can be freely implemented a variety of colors using a general lighting, a small color lamp or color LED in the city for emotional lighting when listening to music. In addition, the present invention may have various shapes and configurations, without being limited to a stand type.

As described in detail above, the present invention is a light that can naturally induce human emotions by selecting a mode of lighting, such as when learning, using the emotional lighting system, taking a break, inducing sleep, etc. There is an effect that can be utilized. In addition, since existing audio systems and lighting systems can independently induce desired emotions as well as interrelated functions, there is an effect that can be applied to emotional engineering.
