<p>A lighting apparatus having a sound sensing function is provided to control the color, expression, and operation of a lighting instrument according to the pitch and tempo of a sound signal outputted from a sound instrument. A lighting apparatus having a sound sensing function includes a microphone(110), a frequency analyzer(120), a memory(130), a controlling unit(140), and an illumination adjusting unit(150). The microphone(110) obtains an external sound source. The frequency analyzer(120) analyzes a frequency of an analog signal obtained in the microphone(110), and separates and processes one of the pitch or tempo of the sound source into a digital signal. The memory(130) stores reference data for controlling a lighting instrument according to the external sound source. The controlling unit(140) generates a control signal which controls more than one among the intensity of illumination, saturation, and rotation speed of the lighting instrument corresponding to the data processed in the frequency analyzer(120) based on the data stored in the memory(130). The illumination adjusting unit(150) adjust the intensity of illumination according to the control signal of the controlling unit(140).</p> |
