This prototype shows a lamp with 3 phases. We know that different light has different effects on people. This lamp provide people suitable light according to different activity. Phase one is working light -- a blueish light that helps with concentration. Phase two is a yellowish light that suit for relaxing daily life. Phase three is party time, when the light will change according to the music.
