Abstract

[PROBLEMS] In order to continue lighting for a certain period of time after switching off with a conventional lighting fixture, a battery is required in the case of emergency lights, and a timer is required in the case of hotel lighting. Was unsuitable due to high equipment costs.
In the present invention, after a switch 2 is actuated or after a power failure, a power supply circuit 12 for supplying power to a lighting fixture 7 from a charged capacitor 6 of the power supply circuit 12 is built in the lighting fixture 7 so that an existing modification is made. Without turning on, it is possible to turn on the light at the time of extinction and timed lighting at the time of power failure. Further, after the operation of the switch 2, the timed lighting is made possible by supplying power from the power source 1 to the luminaire 7 for a certain period of time by the delay relay 8 of the power circuit 12.

Description

  The present invention is a technique related to a lighting fixture that keeps on for a certain period of time when the light is extinguished or when a power failure occurs.

  The conventional lighting fixtures turned off as soon as the switch was turned off. Exceptionally lit lighting fixtures such as buildings, halls, hotels, factories, underground malls, etc. stipulated by the Fire Service Act have been on for a certain period of time after being turned off.

Problems that the device tries to solve

  The conventional lighting fixture is composed of a switch (2) and a lighting fixture (7). In order to continue lighting for a certain period of time after the switch is turned off, a battery is necessary for an emergency light, and a timer is necessary for turning off a regular lighting fixture. For this reason, small-scale individual lighting is not suitable because of high equipment costs. Also, in the case of existing facilities, remodeling work was required.

Means for solving the problem

In order to solve the above problems, in the present invention, a power supply circuit (12) including a condenser (6) or a delay relay (8) is incorporated in the lighting fixture (7).
In the case of FIGS. 1 and 2, when the light is turned off by the switch (2) or at the time of a power failure, the power is supplied from the charged capacitor (6) in the power circuit (12) to the lighting device (7). The timed lighting at the time of power failure was made possible. Also, in the case of FIG. 3, when the light is turned off by the switch (2), the time is turned on by supplying power from the power supply (1) to the lighting fixture (7) for a certain time by the delay relay (8) in the power circuit (12). Made possible.

Embodiment of invention

Next, an embodiment of the present invention will be described.
FIG. 1 shows an embodiment in which lighting of the lighting fixture (7) is continued for a certain period of time at the time of extinguishment, power failure. The lighting fixture <7> attached to the power source <1> is turned on and off by turning on and off the switch <2>. The lighting fixture (7) is an incandescent bulb, a fluorescent lamp, or other fixture that emits light by electric power. 1 is the power supply circuit (12), and FIGS. 2 and 3 are also common. In FIG. 1, the power circuit (12) is composed of a lighting relay (3), a relay A (4), a relay B (5), and a condenser (6), and is built in the lighting fixture (7). , Outside the power supply circuit (12).
When the switch (2) is set to “ON”, power is supplied from the power source (1) to the lighting fixture (7) and the lighting fixture (7) is turned on. At this time, the lighting relay (3) is excited, the relay A (4) is turned on, the relay B (5) is turned off, and the capacitor (6) is charged with electric power.
When the switch (2) is set to “OFF”, the power supplied from the power source (1) to the lighting fixture (7) is stopped. At this time, the lighting relay (3) is demagnetized, the relay A (4) is turned off, the relay B (5) is turned on, and power is supplied to the lighting fixture (7) from the charged capacitor (6) for a certain period of time. Lighting fixture (7) continues to be lit. The lighting is performed until the power supply from the capacitor (6) is stopped, and when the power supply from the capacitor (6) is stopped, the light is naturally turned off. The lighting time after the switch is turned off is determined by the charge capacity of the capacitor (6). As described above, it is possible to perform timed lighting when the light is turned off. When the power supply ▲ 1 ▼ goes out of power while the switch ▲ 2 is in the “ON” state, the switch ▲ 2 ▼ becomes the same as “OFF”, and the timed lighting at the time of the power failure becomes possible.
FIG. 2 shows an embodiment in which the lighting fixture <7> is turned on for a certain period only when the power source <1> is turned off, while the switch <2> is turned off. When the switch (2) is set to “ON”, the low voltage relay (11) is energized, the relay A (4) is turned on, the relay B (5) is turned off, and the relay C (10) is turned off. Does not light up. However, if the power supply (1) goes out of power while the switch (2) is "ON", the low voltage relay (11) is demagnetized, the relay A (4) is OFF, the relay B (5) is ON, and the relay C (10) is turned ON, and the power is supplied to the lighting fixture (7) for a certain time from the charged capacitor (6), so the lighting fixture (7) is lit. When the power supply (1) is restored, the low voltage relay (11) is energized, the relay A (4) is turned on, the relay B (5) is turned off, the relay C (10) is turned off, and the lighting fixture (7) is turned off. The capacitor (6) is charged with electric power.
FIG. 3 shows an embodiment in which lighting of the lighting fixture (7) is continued for a certain period of time only when the light is turned off. A delay relay (8) excited by the switch (2) is installed in the power circuit (12). When the switch (2) is set to “OFF”, the automatic switch (9) is turned off by a delay relay (8) after a certain period of time, and the power supplied to the lighting device (7) from the power source (1) is stopped. . When switch (2) is set to “ON”, automatic switch (9) is immediately turned “ON” by delay relay (8).

Effect of device

  According to the present invention, it is possible to turn on the lighting fixture (7) in a timely manner without modifying the lighting fixture or the lighting circuit. Accordingly, since the lighting fixture {circle over (7)} is lit for a certain time when the light is turned off, when leaving the room where the lighting fixture {circle over (7)} is left, the lighting fixture can be left in the illuminated state. In addition, even when the power is stopped urgently due to an earthquake, fire, etc., the lighting fixture (7) continues to be lit in a timely manner, so it is possible to ensure the safety of leaving the room. It is possible to turn on the light only at the time of power failure, and it becomes an evacuation light.
