Document Type and Number:
WIPO Patent Application WO/2010/150701
Kind Code:
A1
Abstract:
Provided is an automatic flashing control device for automatically flashing an illumination lamp installed within a building in accordance with only the variation of brightness of the installed location.
The automatic flashing control device is comprised of a photoelectric conversion element (1) wherein a detection visual field of natural light and a radiation field of the illumination lamp are at least partially overlapped; a first comparison circuit (2) which generates a lighting signal when the level of an output from the photoelectric conversion element (1) is lower than a predetermined lighting start level; a memory circuit (5) which stores data of the output level output from the photoelectric conversion element (1) after the lighting of the illumination lamp; a second comparison circuit (8) which compares the level after the lighting, stored in the memory circuit (5) with the level of the output from the photoelectric conversion element (1) and which generates a light-off signal when the level of the output from the photoelectric conversion element (1) is higher than the stored level after lighting.
