Entrance illumination controller
专利汇可以提供Entrance illumination controller专利检索，专利查询，专利分析的服务。并且PURPOSE: To control ON-OFF conditions of the lighting at an entrance in a natural manner by putting the lighting off with the reception of an entrance lock and a comparator when an entrance lock is made from the outside, while by putting on under specified conditions when it is unlocked.
CONSTITUTION: This controller is adapted to control ON-OFF conditions of an entrance lighting unit 11 and composed of an entrance lock 20, illuminance detector 30, controller 60 and the like. The lock 20 is provided with a switch unit 21 capable of outputting a signal of locking or unlocking from the outside while the detector 30 composed of a CdS sensor 31. The controller 60 is composed of microcomputer 61 and relay 62, and puts OFF the lighting unit 11 with the reception of the outputs from the lock 20 and a comparation unit 40 when the lock 20 is made form the outside while puts ON under the conditions that the illuminance is lower than a specified level when the lock 20 is unlocked. It is thus possible to control the ON-OFF conditions of entrance lighting in a natural manner.
