Description

[Detailed description of the invention] Zero light #3A is a lighting device used in places where there is little foot traffic, such as hotel corridors, or conversely, where people frequently come in and out, such as hotel rooms. This invention relates to a self-contained lighting device that automatically turns on and off according to people passing by, coming in and going out, and turning on and off.

Generally speaking, at home, it is the same as in hotels, but there is a lot of wasteful energy consumption due to forgetting to turn off lighting equipment.
Particularly in hotels and the like, lighting fixtures in hallways are usually turned on all the time even when no one is passing through due to the complexity of management, which is undesirable in terms of energy conservation. In such cases, it is necessary to turn on the lights only when people use the entire corridor, and it is necessary to keep the lights on all the time.

Conventionally, various methods have been tried to automatically turn on and off lighting devices used under such conditions.

A typical example is one that uses an ultrasonic sensor, but this device can detect the entire human body when installed in any room with an automatic light on/off #iA device that incorporates an ultrasonic sensor. Although it worked, there was a drawback that the ultrasonic waves penetrated the entire wall of the seventh room and detected the human body in the next room, causing the lights to turn on and off unexpectedly.

In view of the above circumstances, an object of the present invention is to automatically turn on and off all lighting devices appropriately and to suppress energy waste as much as possible by detecting a human body.

The automatic on/off lighting device according to the present invention, which has been made to achieve all of the above objects, has an infrared sensor for detecting a human body;
0N-OFF depending on whether a human body is detected by this sensor
The point is that the output end of the controller integrally incorporating the operating switching element and the input end of the F3AA equipped with the switching element are electrically connected.

The effects of the present invention having such a characteristic configuration are as follows.

By using an infrared sensor that takes full advantage of the thermal effect of infrared rays emitted from the human body, Senbu can detect infrared rays from only the human body, preventing malfunctions such as detecting a human body in the next room. It can be held down. Moreover, by integrally incorporating the switching element and controller, which are composed of electronic equipment that electrically connects the sensor and the lighting, together with the sensor,
We are now able to provide a complete range of products that are smaller and lighter, have excellent EJL handling properties, and are useful for energy conservation.
