Document Type and Number:
WIPO Patent Application WO/2010/104296
Kind Code:
A2
Abstract:
The present invention relates to an alarm clock comprising: a power supply unit; a key input setting unit (110) having a lamp operating time setting portion (111) and an alarm operating time setting portion (112); a lamp (140); a microcomputer (120) in which a timer programmer is stored, and which outputs a lamp operation control signal and a pulse width signal at the lamp operating time, and outputs an alarm control signal at the operating time of an alarm module (160); a time display unit (170); said alarm module (160) which is turned on and off in accordance with the alarm control signal supplied by the microcomputer (120) to output a voice alarm signal; a lamp power supply control unit (130) which is turned on and off in accordance with the lamp operation control signal output by the microcomputer (120) to control the supply of power to the lamp (140); and a lamp current adjustment unit (160) which gradually increases the amount of current of the lamp (140) in accordance with the pulse width signal output by the microcomputer (120). The alarm clock of the present invention is advantageous in that it generates an alarm sound after a lamp is gradually faded in to become fully lit, to thereby protect users from being startled by a sudden alarm sound and from being dazzled by a sudden lighting of the lamp.
