Description

(4) The present invention relates to a fluorescent lamp with an emergency light mounting connector that can secure necessary light for disaster prevention even if an unexpected power failure occurs due to a lightning strike or an earthquake.

At night, if you are hit by an unexpected power failure due to lightning or an earthquake, the lights in the room will be turned off all at once and you will not be able to see anything. Therefore, many families prepare flashlights in case of unexpected power outages. However, flashlights are not commonly used, and most homes have flashlights stored in shelves or in drawers. For this reason, it is often difficult to find a flashlight in the dark, and it is often difficult.

Also, for example, as shown in Patent Literature 1, a fluorescent lamp-type guide lamp used by being plugged into a household outlet has been proposed. In the example shown in Patent Document 1, a guide light is usually inserted into a household outlet, and when a power failure occurs, the guide light is turned on. For this reason, even if a power failure occurs, minimum light can be secured, and it is not necessary to search for a flashlight in the dark. In addition, it can be used as a flashlight because it keeps lighting even when it is removed from the outlet.

The light can be secured for the most part.

(4) That is, as shown in FIG. 4A, if a power failure occurs while the fluorescent tube 2 is on, the fluorescent tube 2 is turned off, and the light cannot be secured. When a power failure occurs, the light bulb 21 of the emergency light unit 20 is turned on, as shown in FIG. As described above, when a power failure occurs, the emergency light unit 20 is turned on. Therefore, the illumination of the emergency light unit 20 can secure a certain amount of light at night even when a power failure occurs.

FIG. 5 shows an example of a circuit configuration of the fluorescent lamp 10 and the emergency light unit 20. As shown in FIG. 5, the fluorescent lamp 10 includes a fluorescent tube 2, a ballast 31, a glow lamp 13, capacitors 32 at both ends of the glow lamp 13, and a switch 15.

(4) The plug 6 is connected to the rosette 7, and commercial power is supplied to the fluorescent lamp 10 via the power cables 5a and 5b. In addition, cables 33a and 33b are branched from the power cables 5a and 5b, and the terminals 16a and 16b of the emergency light mounting connector 16 are connected to the cables 33a and 33b.

The emergency light unit 20 includes a voltage detection circuit 41, a comparator 42, a switch control circuit 43, a switch circuit 44, the light bulb 21, and a battery 45. The plug 23 is inserted into the emergency light mounting connector 16, and the terminals 16 a and 16 b of the emergency light mounting connector 16 are connected to the terminals 23 a and 23 b of the plug 23.

When the fluorescent tube 2 of the fluorescent lamp 10 is turned on, the switch 15 is turned on. When the switch 15 is turned on, current flows from the commercial power supply 30 to the filaments 34 a and 34 b of the fluorescent tube 2 through the rosette 7, the plug 6, the power cables 5 a and 5 b, the glow lamp 13, the ballast 31, and the switch 15. Thereby, the periphery of the filaments 34a and 34b of the fluorescent tube 2 is heated, and electrons are emitted from the filaments 34a and 34b. When the current continues to flow through the glow lamp 13, the temperature inside the glow lamp 13 increases, and the glow lamp 13 is turned off. When the glow lamp 13 is turned off, a high voltage is generated at both ends of the ballast 31, and this high voltage is applied to the electrodes of the fluorescent tube 2, discharge of the fluorescent tube 2 is started, and the fluorescent tube 2 is turned on.

The emergency light unit 20 is configured to detect the occurrence of a power failure by monitoring the voltage at the terminals 16a and 16b of the emergency light mounting connector 16, and to turn on the light bulb 21 when the power failure occurs.

That is, the commercial power supply 30 is supplied from the rosette 7 to the terminals 16a and 16b of the emergency light mounting connector 16 via the plug 6, the power cables 5a and 5b, and the cables 33a and 33b. This commercial power supply is detected by the voltage detection circuit 41 via the terminals 23a and 23b of the plug 23 and the cables 46a and 46b. The detection voltage of the voltage detection circuit 41 is supplied to a comparator 42, which compares the detection voltage with a predetermined voltage from a reference voltage source 46. The output of the comparator 42 is supplied to the switch control circuit 43. The switch control circuit 43 generates a switch control signal according to the output of the comparator 42.

(4) When no power failure occurs, the input voltage of the voltage detection circuit 41 becomes higher than a predetermined voltage. At this time, the switch control circuit 43 outputs a switch-off control signal. The switch-off control signal is supplied from the switch control circuit 43 to the switch circuit 44, whereby the switch circuit 44 is turned off. When the switch circuit 44 is off, the current from the battery 45 is cut off by the switch circuit 44, and the light bulb 21 is turned off.

(4) When a power failure occurs, the input voltage of the voltage detection circuit 41 becomes lower than a predetermined voltage. At this time, a switch-on control signal is output from the switch control circuit 43, and the switch circuit 44 is turned on. When the switch circuit 44 is turned on, the current from the battery 45 is supplied to the bulb 21 through the switch circuit 44, and the bulb 21 is turned on.

As described above, in the embodiment of the present invention, the emergency light unit 20 that lights up when a power failure occurs is detachably attached to the fluorescent light 10. This has the following advantages.

First, as shown in FIG. 1, the emergency light unit 20 is installed in the fluorescent lamp 10 in a normal state. Usually, the fluorescent lamp 10 is suspended from the ceiling in the middle of the room. This is the position that illuminates the entire room most efficiently. Therefore, when the emergency light unit 20 is installed in the fluorescent light 10, even when a power failure occurs, the entire room can be efficiently illuminated.

In addition, in this embodiment, the emergency light unit 20 is attached to the fluorescent light 10. As described above, since the emergency light unit 20 is attached to the fluorescent light 10, there is no trouble in the place where the emergency light unit 20 is stored when not in use. Also, since the emergency light unit 20 is housed in the fluorescent light 10, the appearance is not spoiled.

The emergency light unit 20 is detachable from the fluorescent light 10. Therefore, if the emergency light unit 20 is detached from the fluorescent light 10 at the time of a power failure, it can be used as a flashlight. Also, if the emergency light unit 20 is detached from the fluorescent light 10, the battery check and the replacement of the light bulb can be easily performed.

As shown in FIG. 6, when the lighting switch 18 is provided on the wall 50 of the room, it can be easily inspected whether the emergency light unit 20 is operating properly. That is, if the switch 18 for lighting the wall of the room is turned off, the supply of the commercial power 30 output from the rosette 7 can be stopped, and the same state as at the time of the power failure can be created. Therefore, whether or not the emergency light unit 20 is operating properly can be inspected by checking whether the light bulb 21 of the emergency light unit 20 is turned on when the switch 18 for lighting the wall of the room is turned off. During normal use, the switch 18 for illuminating the wall of the room may be turned on, and the switch 15 may be used to turn on or off the fluorescent tube 2.

Second embodiment.
FIG. 7 shows a second embodiment of the present invention. In the above-described first embodiment, the ballast 31 is used as the lighting method of the fluorescent tube. In the second embodiment, an inverter-type lighting circuit is used.

In addition, cables 33a and 33b are branched from the power cables 5a and 5b, and the terminals 16a and 16b of the emergency light mounting connector 16 are connected to the cables 33a and 33b. The inverter type lighting circuit 51 rectifies the commercial power supply 30 and switches at high frequency to discharge the fluorescent tube 2. When the inverter type lighting circuit 51 is used, the light amount of the fluorescent lamp can be controlled.

制 御 A control circuit 52 is provided for the inverter-type lighting circuit 51 to control the lighting and extinguishing of the fluorescent tube 2 and the light amount of the fluorescent lamp. When the user operates the remote controller 54, an infrared signal is output from the remote controller 54. This infrared signal is supplied to the control circuit 52 via the light receiving section 53. Thus, the user can remotely control the turning on / off of the fluorescent tube 2, the light amount of the fluorescent lamp, and the like using the remote controller 54.

The emergency light unit 20 includes a voltage detection circuit 41, a comparator 42, a switch control circuit 43, a switch circuit 44, a light bulb 21, and a battery 45, as in the first embodiment. . The plug 23 is mounted on the emergency light mounting connector 16, and the terminals 16 a and 16 b of the emergency light mounting connector 16 are connected to the terminals 23 a and 23 b of the plug 23.

Also in the second embodiment, the emergency light unit 20 is detachably mounted in the fluorescent lamp 10, and a power outage occurs and the voltage of the commercial power supply 30 is reduced to a predetermined value, as in the first embodiment. When the voltage becomes lower than the voltage, a switch-on control signal is output from the switch control circuit 43, and the switch circuit 44 is turned on. When the switch circuit 44 is turned on, the current from the battery 45 is supplied to the bulb 21 through the switch circuit 44, and the bulb 21 is turned on. Therefore, even when a power failure occurs and the fluorescent tube 2 is turned off, a certain amount of light can be secured by the light bulb 21 of the emergency light unit 20.

Also, as in the case of the first embodiment shown in FIG. 6, if there is a lighting switch on the wall of the room, if the switch for lighting the wall of the room is turned off, the output from the rosette 7 is obtained. Commercial power supply can be turned off, creating the same state as during a power outage. Therefore, whether or not the emergency light unit 20 is operating properly can be inspected by checking whether or not the light bulb 21 of the emergency light unit 20 is turned on when the lighting switch on the wall of the room is turned off. At the time of normal use, the switch for lighting the wall of the room is turned on, and the turning on and off of the fluorescent tube 2 and the amount of lighting are controlled by the remote controller 54.

The present invention is not limited to the above embodiments, and the above embodiments may be appropriately combined. The present invention is not limited to the above-described embodiment, and various modifications and applications can be made without departing from the gist of the present invention. For example, in the above-described embodiment, an annular tube is used as the fluorescent tube 2, but a linear fluorescent tube may be used.
