Title:
ALARM CLOCK INTEGRATED WITH LAMP AND METHOD FOR CONTROLLING OPERATION OF LAMP THEREBY
Document Type and Number:
WIPO Patent Application WO/2014/051302
Kind Code:
A1
Abstract:
The present invention relates to an alarm clock integrated with a lamp and a method for controlling the operation of a lamp thereby, wherein the alarm clock integrated with a lamp further comprises an illumination sensor (181) and a sensor connection unit (182), and a microcomputer (120) which outputs a sensor operation control signal to the sensor connection unit (182) at a lamp operation time set by a lamp operation time setting unit (111), compares a current illumination value inputted from the illumination sensor (110) with an initial operation illumination value of a lamp (140) stored therein after the illumination sensor (181) is operated, and outputs a pulse control signal to a lamp current control unit (150) so as to change an output of the lamp (140) for changing the illumination value of the lamp (140) to a predetermined illumination value when the initial operation illumination value is less than the current illumination value, thereby changing the lamp illumination value according to the surrounding brightness when the brightness of the lamp is less than the surrounding brightness at the initial lighting time of the lamp.
