Abstract

PURPOSE:To easily confirm the position of a luminaire by the eyes by lighting an incandescent lamp or fluorescent lamp through a lighting control means according to a signal emitted when the access of a man is detected, and lighting it for a determined time with a low illuminance capable of identifying the circumference. CONSTITUTION:When the movable contact of a flashing change-over switch 2 is rotated, a contact D is opened, and a terminal A closes a contact E. A power source circuit 10 for supplying a power to a man detecting sensor circuit 8 is operated to operate the circuit 8. In this state, all of an incandescent lamp 3 and fluorescent lamps 4, 5 are extinguished. When the access of a man is detected by the circuit 8, a man detection signal is transmitted from the circuit 8 to a timer circuit 7, and on the receipt of the man detection signal, the circuit 7 operates a timer, and a driving circuit 6 closes a contact 11 for a determined time to light the incandescent lamp 3. Since a resistor 12 is connected in series to the incandescent lamp 3, however, the input current is limited, and the lamp 3 is lighted with a luminance less than about 10% of ordinary lighting, and even when it is suddenly lighted in the darkness, no glare is felt.

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for a lighting fixture which detects the approach of a person when the light is turned off and turns on with a low luminous flux.

2. Description of the Related Art Conventionally, a person detection circuit and a timer circuit have been provided in order to automatically turn on the illumination when approaching a room in which the illumination is turned off. A lighting device having a function of being turned on for a certain time and then turned off has been developed. Since the above lighting device does not need to operate the switch for lighting, it is not necessary to feel for the position of the switch in the darkness, and it is an effective lighting device when holding an object in both hands.

However, in the above-mentioned prior art, since the lighting fixture is lit in a full-light state for a certain period of time after detecting the approach of a person, it should be taken into consideration that the minimum necessary illuminance is obtained. However, it is not appropriate to act without disturbing the sleep of other people, for example, when another person enters the room while sleeping, or when a plurality of people start up alone while sleeping. Also, because all the lights turn on rapidly in the dark,
There was a problem of feeling glare instantly. It is an object of the present invention to obtain a lighting device that detects the approach of a person and lights with a low illuminance that allows the surroundings to be identified.

SUMMARY OF THE INVENTION The above-described object is to provide a lighting circuit for an incandescent lamp or a fluorescent lamp or a lighting device having both of them, and a drive circuit for the incandescent lamp or the fluorescent lamp.
A timer circuit and a person detection sensor circuit are provided with lighting control means, and when the incandescent lamp or the fluorescent lamp or both of them are in an off state, the incandescent lamp or the fluorescent lamp is detected by a signal emitted by detecting the approach of a person. This is achieved by illuminating through the lighting control means and illuminating for a predetermined time with a low illuminance that can identify the surroundings.

A lighting circuit according to the present invention comprises a lighting circuit for driving an incandescent lamp or a fluorescent lamp, a timer circuit, and a person detecting sensor circuit, and a person detecting signal when the person detecting sensor circuit detects an approach of a person. To the timer circuit, the timer circuit starts the timer operation upon receiving the detection signal, and while the signal continues, the drive circuit lights up by closing the contact of the incandescent lamp or the fluorescent lamp circuit. On this occasion,
Since the lighting circuit for the incandescent lamp or the fluorescent lamp is connected to a lighting control means such as a resistor for controlling an input current, a switching element for performing ignition control, and a lighting control circuit, the incandescent lamp or the fluorescent lamp is connected. Does not turn on 100% of all light, and the brightness is such that the surroundings can be identified, for example, 10
It is possible to control so that only about %% of the luminous flux is emitted.

Rotates in the clockwise direction to open and close between the terminal A and each contact. Terminal A and contact B of the flashing changeover switch 2
When F and F are closed, the fluorescent lamps 4 and 5 are turned on.
When the movable contact of the flashing changeover switch 2 is rotated, the terminal A and the contacts B and F are opened, the terminal A is closed between the contact C, and only the fluorescent lamp 4 is turned on. When the movable contact of the flashing changeover switch 2 is further rotated,
Since the contact A is opened between the contacts C and the contact A is closed to the contacts D, only the incandescent lamp 3 is turned on. Next, when the movable contact of the flashing changeover switch 2 is rotated, the contact D is opened and the terminal A is closed between the contact E and the terminal E. At this time, the power supply circuit 10 that supplies power to the human detection sensor circuit 8 operates, and the human detection sensor circuit 8 operates. In this state, the incandescent lamp 3 and the fluorescent lamps 4 and 5 are all off. Therefore, when the person detection sensor circuit 8 detects the approach of a person, the person detection sensor circuit 8 sends a person detection signal to the timer circuit 7. When the timer circuit 7 receives the human detection signal, the timer operates, and the drive circuit 6 closes the contact 11 and turns on the incandescent lamp 3 for a predetermined time. However, since the resistor 12 is connected in series to the incandescent lamp 3, the input current is limited, and the incandescent lamp 3 is lit with a brightness of about 10% or less of the normal lighting. Second Embodiment A second embodiment shown in FIG. 2 is an example in which a human detection circuit unit is provided in a fluorescent lamp lighting circuit with a remote control function.

The fluorescent lamp 4 is turned on by a control signal from 0. In the present embodiment, the remote control light receiver 18 is programmed in the microcomputer 19 so that an arbitrary lighting state can be set by receiving a signal from an external remote control transmitter. If a person approaches when both the incandescent lamp 3 and the fluorescent lamp 4 are off, the person detection sensor circuit detects the person's approach and outputs a person detection signal. When the microcomputer 19 receives the human detection signal, it outputs a signal for a predetermined time to the drive circuit 6. The drive circuit 6 operates the switching element 21 to turn on the incandescent lamp 3. The incandescent lamp 3 can be dimmed and turned on by controlling the ignition of the switching element 21. Third Embodiment A third embodiment shown in FIG. 3 is provided with the light detecting element 22 in the second embodiment, and the fluorescent lamp 4 is turned on when the approach of a person is detected only when the ambient illuminance is low. This is an example. When the person detection signal generated by the approach of the person 9 in the off state is input to the microcomputer 19 by the person detection sensor circuit 8, the microcomputer 19 outputs a lighting signal to the lighting control circuit 20 for a predetermined time. Output. At this time, when the ambient illuminance satisfies a predetermined value, the output signal of the microcomputer 19 is canceled and the fluorescent lamp 4 is not turned on. When the ambient brightness is insufficient with respect to a predetermined value, the lighting control circuit 20 receives a lighting signal, and the fluorescent lamp lighting circuit 1
