The invention discloses an electronic alarm clock device and a realization method thereof. The electronic alarm clock device comprises a microprocessor as well as a clock chip and a memory which are in two-way communication connection with the microprocessor; the output ends of the microprocessor are connected with the input end of a display screen and the input end of a color light emission device respectively; and the input ends of the microprocessor are connected to the output end of a battery and the output end of a key respectively. According to the electronic alarm clock device and the realization method thereof of the invention, the conventional LCD display is adopted to display time, and the ringing time of the alarm clock is also indicated by colors; and a user can edit the ring time of the alarm clock and the light emission colors of the color light emission device in six time periods before the ringing time, so that the color light emission device can emit colorful light according to the set colors, and therefore, the user can judge a time duration from current time to the ringing time according to the light emission colors, quickness and convenience can be realized, and discomfort brought about seeing the time at night can be eliminated. The electronic alarm clock device has the advantages of adjustability in light emission intensity, wide adaptability, low cost and novel structure, and can satisfy the needs of users.
