JPH0730499U - Lighting device with human body detector - Google Patents

Abstract

(57) [Summary] (Correction) [Purpose] In a device that detects the movement of the human body and turns on the light, detects the disconnection of the light bulb of the illumination lamp and displays it on the device side. [Structure] A human body detector 1, an illuminance detection unit 4 for detecting whether it is day or night, a control unit 2 for controlling to turn on an illumination, and a disconnection detection unit 5 for detecting disconnection of a wiring to an illumination lamp.
And a disconnection display means 6 for displaying the disconnection.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lighting device with a human body detector that can turn on an illumination lamp for a preset time when a human body is detected.

[0002]

[Prior art]

 An illumination device with a human body detector that has been put to practical use uses a passive infrared system (passive infrared detection system) as a human body detector, and when the human body is detected, the illumination lamp is turned on for a preset time. It lights up. An illuminance discrimination function is added to such a device, and the above-mentioned operation can be performed only in the night without operating in the daytime. Since the lighting device with a human body detector operates only when a human approaches, it is often used as an energy-saving lighting or a crime prevention light.

[0003]

[Problems to be solved by the device]

 Conventional lighting devices with human body detectors are often installed in high places that are out of the reach of people so as not to be mischievous when used as crime prevention lights. In addition, since the illuminance discrimination function works after installation, it does not operate during the daytime. Therefore, it is not possible to detect the bulb out of the lighting bulb until night. Also, since it is installed at a high place, it is difficult to replace the bulb at night, and it is inconvenient from a maintenance point of view that the bulb burnout can be detected only at night. It

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above, and is characterized by detecting that a light bulb of an illuminating lamp is broken and displaying the same day or night.

[0005]

According to the present invention, when the light bulb of the illuminating lamp is broken, it is notified by a display. Therefore, even during the daytime when the illuminating device with the human body detector is not turned on, whether the illuminating lamp is normal or not can be seen by looking at the main body. It will be possible to confirm, and the above-mentioned problems can be resolved.

[0006]

【Example】

 FIG. 1 is a block diagram of an embodiment of the present invention. The signal from the human body detector 1 and the signal from the illuminance detection unit 4 are transmitted to the control means 2 and the illumination lamp 3 is turned on as a result of the determination process. When the output of the illuminance detection section 4 is a signal indicating daytime, no signal is output from the control means 2 even if there is a signal from the human body detector 1, and the illumination lamp 3 is not turned on. Only when the output of the illuminance detection unit 4 is a signal indicating night, the control means 2 lights the illumination lamp 3 in response to the signal from the human body detector 1. The illuminating lamp 3 is monitored by the disconnection detection means 5, and when not disconnected or when disconnected, transmits a signal corresponding to each to the disconnection display means 6, and the disconnection display means 6 performs a corresponding display. The disconnection display means can be selected from various ones such as LED lighting or blinking, and sound display. The present invention can also be applied to a human body detector that utilizes the Doppler effect of ultrasonic waves or microwaves, or a device that uses a reflected light type.

[0007]

[Effect of device]

 As described above in detail, according to the present invention, in the lighting device with a human body detector, the broken state of the light bulb of the lighting can be confirmed by looking at the main body, especially during the daytime, which is very convenient for maintenance. Become.
