PURPOSE: An emotional lighting device with a chaos rhythm output function is provided to improve psychological stability and concentration of a user by outputting a natural sound signal corresponding to a color temperature of an LED lamp. CONSTITUTION: A natural sound file(321) stores natural sound information of a chaos rhythm as a file. A memory(303) outputs a natural sound corresponding to a color temperature of light and mounts alpha wave algorithm of a frequency band. A control module(301) selects and outputs a natural sound signal corresponding to a color temperature range. A sound modulation module(313) modulates the natural sound information and an alpha wave signal and outputs the modulated signal. A signal amplification module(315) amplifies an analog signal with a preset level and supplies the amplified signal to a speaker(217). A noise detection module(309) detects a peripheral noise signal. A light quantity detection module(311) measures the light quantity. |
