The present invention relates to a device for controlling lighting devices for visual effects using lighting devices.

In recent years, a lighting device has been developed with a function of simply illuminating a dark place, and technology for developing various visual effects has been developed. For example, in the case of a stage lighting or a landscape lighting implemented by a conventional LED lighting device, the lighting effect is periodically flickered at predetermined time intervals according to a predetermined color and a driving method in accordance with a preset program to produce a visual effect. In addition, such an operation is provided together with music reproduction to further satisfy people's emotions.

However, in the case of the above-described prior art lighting apparatus, the lighting apparatuses flicker independently of the music by periodically repeating operation by a predetermined method. Therefore, although the above-described illumination devices can provide a visual effect, they have a disadvantage in that it is difficult to visually produce a characteristic characteristic of music.

Accordingly, one object of the present invention is to provide an apparatus for controlling lighting devices that can produce various visual effects.

It is also an object of the present invention to provide an apparatus for controlling lighting devices that enable a user to visually produce unique characteristics of music.

According to an aspect of the present invention, there is provided an apparatus for controlling lighting devices, comprising: an input unit for receiving a user's operation; A music reproducing unit for reproducing a sound source of the music; An external device connection unit for transmitting and receiving signals; A plurality of lighting groups are grouped into a plurality of lighting groups, a corresponding frequency band is designated for each of the lighting groups, and upon reproduction of the music according to a user's operation through the input unit, A control signal for controlling a corresponding lighting group for each frequency band according to an output level of each frequency band divided in a frequency spectrum of the sound source through the external device connection unit, To a device that is connected to the network.

As described above, by using an apparatus for controlling lighting devices, various visual effects can be produced. In addition, the unique characteristic of music can be visually produced to satisfy people's emotions.
