Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically blinking a lighting fixture suspended from a ceiling in a room,
In particular, the present invention relates to an automatic blinker that detects the presence or absence of a person and automatically blinks a lighting device.

[0002]

2. Description of the Related Art Conventionally, an automatic blinker for automatically turning on and off a lighting fixture or the like using a sensor for detecting a person has been widely used. As a blinker for automatically blinking an indoor lighting device, a blinker for hanging ceiling is known. In this case, a power supply control element consisting of a sensor and a switch element is housed inside the case, a hook blade is provided on the top of the case, and a hook-type outlet is provided on the bottom of the case. Then, a lighting fixture is connected to a hook-type outlet on the lower surface, and a switch element is operated according to a detection operation of a sensor to supply power to the lighting fixture. Some sensors are mounted on arms that protrude from the case.

[0003]

The above-mentioned conventional automatic flasher has the following problems. (1) A sensor cannot be installed toward an optimal door or the like for detecting entry and exit of a person. The hanging ceiling can be turned 180 degrees to change the mounting angle because of the point symmetric structure, but the angle cannot be freely selected according to the direction of the door. In order to freely select an angle, it is necessary to temporarily remove and reattach the hooking ceiling closet that has already been constructed. In the case of the one with the arm, the detection area can be selected only by changing the angle of the sensor, but in many cases, the lighting fixture suspended below can be a hindrance and the optimum orientation cannot be selected. (2) This type of automatic flasher has a structure in which an existing hanging ceiling type lighting fixture is once removed and attached between the hanging ceiling closet and the lighting fixture. As a switch operated when stopping the automatic blinking, a switch provided on a wall surface or a switch provided on a lighting fixture body is used. For this reason, when stopping automatic blinking, such as when going to bed, it is necessary to get up and operate the existing switch, leaving a surface that requires complicated operation in spite of being automatic.

The present invention has been made in consideration of the above points, and has as its object to provide an automatic blinker for a ceiling light which can set a sensor for detecting a person to an arbitrary position and an arbitrary direction. I do.
