Document Type and Number:
Japanese Patent JP2014170719
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve a problem found in the prior art devices using earthquake sensing switches that many of the prior art devices are portable types such as a flash lamp and the like and many cases show that it is difficult to search for the prior art devices in emergencies such as earthquake and the like.SOLUTION: When earthquake occurs during sleeping at night, it is quite dangerous to grope a wall switch or search for a flash lamp in confusion in the dark. However, an earthquake sensing switch controller of this invention changes ceiling luminaire devices and wall luminaire devices into earthquake sensing luminaire devices merely by connecting the earthquake sensing switch controller of this invention to the existing ceiling luminaire devices and wall luminaire devices. With this arrangement, even if during sleeping, occurrence of earthquake enables them to automatically keep their usual brightness. In a usual situation, it is possible to turn on or off a luminaire device manually through a wall switch.
