BACKGROUND OF THE INVENTION
The present invention relates to a lighting fixture having a seismic switch.
[0002]
[Prior art]
A conventional example is shown in FIGS. In other words, the connector 102a of the adapter 102 is connected to the hooking sealing body 101 of the ceiling 100, and the hooking sealing cap 105 provided at the upper end of the cord 104 of the lighting fixture 103 is connected to the connected device 102b of the adapter 102.
[0003]
The adapter 102 is provided with a seismic switch 106, a bean ball 107, and a seismic block 108, and the seismic block 108 is operated by the vibration sensing operation of the seismic switch 106 and the bean ball 107 is lit.
Normally, power is supplied to the lighting fixture 103 through the hooking sealing body 101, the adapter 102, the hooking sealing cap 105, and the cord 104. However, if a certain level of vibration is detected, the adapter is turned off even if the lighting fixture 103 is turned off. The bean ball 107 of 102 is automatically turned on to ensure illuminance.

[Problems to be solved by the invention]
However, there has been a risk that a rough operation of the lighting fixture 103 or a vibration when an object hits the hanging type lighting fixture 103 is detected and the lamp is automatically turned on.
Hanging lighting fixtures were vulnerable to earthquakes and tended to be avoided.
Originally, the seismic switch 106 is used for the purpose of detecting a strong shock or falling in a household electric appliance such as a fan heater and shutting off the power supply. However, like the lighting fixture 103, vibration is applied by a normal switching operation or the like. In this case, it was difficult to detect and operate only the shaking caused by the earthquake.
[0006]
Accordingly, an object of the present invention is to provide a lighting apparatus that can be reliably operated by shaking of an earthquake, although it does not malfunction due to daily vibration or shaking generated when operating the instrument.

The seismic switch 3 is mounted in the vicinity of the body mounting portion 5 of the instrument body 1. In the embodiment, the seismic switch 3 is provided on a line connecting the pair of mounting holes 9 of the instrument body 1. Further, a seismic block 30 for lighting the device body 1 in the event of an earthquake is installed in the vicinity thereof, and when the operation signal of the seismic switch 3 is input, the seismic block 30 operates to operate a bean lamp (not shown) or an annular fluorescent lamp. 19 is lit.
[0014]
A lamp socket (not shown) is connected to an annular fluorescent lamp 19 which is attached to the instrument main body 1 and is lit by the operation of the seismic switch 3 and the operation of the inspection switch 21a and the pull switch 21b.
In this lighting apparatus, when there is an earthquake of a certain magnitude, the seismic switch 3 operates, and the bean lamp or the ring-shaped fluorescent lamp 19 is turned on, so that safety can be achieved. In this case, since the seismic switch 3 is provided in the vicinity of the main body mounting portion 5 and the pull switch 21b and the globe 20 are provided on the distal end side of the mounting tool 2, the switch is mounted as shown by an imaginary line in FIG. Even if the tool 2 shakes, since the seismic switch 3 is in the vicinity of the main body mounting portion 5, it is difficult to transmit the vibration generated by the operation of the pull switch 21 b to the seismic switch 3, so that the influence of the switch operation can be avoided. Malfunctions can be prevented.
[0015]
In addition, when the fixture 2 may be shaken when the glove 20 is attached or detached for lamp replacement or when the glove 20 is cleaned, the malfunction of the seismic switch 3 can be prevented, and the construction material, that is, the vibration of the ceiling, that is, the vibration caused by the earthquake. Expand accurately.
The instrument main body 1 has a hooking sealing cap insertion hole 8, the main body mounting portion 5 is composed of a pair of mounting holes 9 formed on both sides of the hooking sealing cap insertion hole 8, and the seismic switch 3 is a pair of the instrument main body 1. Since it provided on the line which connects the attachment hole 9, the shake of the instrument main body 1 at the time of switch operation can be decreased, and switch operation feeling can be improved.
[0016]
Furthermore, since both ends of the fixture 2 are fixed in the direction perpendicular to the direction in which the mounting holes 9 are arranged on both sides of the hooking cap insertion hole 9, the external force (switch pulling force, impact force on the shade) is reduced. In the XX ′ direction of 2, the seismic switch 3 is prevented from swinging by the fixing force of the mounting screw 11, and in the YY ′ direction, the mounting tool 2 is bent as shown in FIG. Reduce the vibration. Thus, since the seismic switch 3 is provided in the direction orthogonal to the shaking direction of the fixture 2, the malfunction of the seismic switch 3 can be prevented more reliably.

In the first embodiment, vibrations of buildings other than earthquakes, such as fine vibrations caused by human behavior on the floor, vibrations associated with the passage of vehicles and the like, are detected by the seismic switch 3 and may be automatically turned on. According to this embodiment, a relatively high frequency of 10 Hz or more that occurs in daily life is absorbed by the elastic bodies 40 and 42 and is not transmitted to the seismic switch 3. That is, since the seismic switch 3 generally detects on / off of the enclosed mercury and the contact point, it is more sensitive to horizontal vibrations than the gravitational direction. Can absorb micro vibrations. On the other hand, the elastic bodies 40 and 42 do not work effectively when the vibration is as low as about 0.2 to 5 Hz, such as an earthquake, and the same behavior as the ceiling 6 of the construction material to which the instrument body 1 is attached is exhibited. Acceleration necessary for operating the seismic switch 3 is applied. Accordingly, the seismic switch 3 does not malfunction due to vibrations applied to the instrument due to the switch operation of the instrument and the maintenance operation of the glove or the like or the daily life vibration, and can operate reliably with the shaking of the earthquake. Others are the same as in the first embodiment.
[0019]
In the embodiment, the seismic switch 3 is provided on a line connecting the pair of mounting holes 9 of the instrument body 1, but this includes the case where the seismic switch 3 is located in the vicinity of the line.
