DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A lighting device according to the present invention is shown in FIGS.
A description will be given based on FIG.

FIG. 1 is a block diagram of a lighting device according to the present invention. FIG. 2 is a side view of the inspection switch of the present invention. FIG. 3 is a perspective view showing an external appearance of the guide light of the present invention, and FIG. 4 is a perspective view showing a state of operating the guide light of the present invention.

Referring to FIG. 1, an emergency lighting device as a lighting device includes a lamp 11, a lighting circuit unit 12, a storage battery 14, and a check switch 15. Lamp 11
Is an incandescent lamp. The lighting circuit 12 turns off the lamp 11 during normal times, and turns on the lamp 11 by power supply from the storage battery 14 in an emergency such as an earthquake or fire.

The storage battery 14 is, for example, a Ni-Cd storage battery, which is charged by power supply from the commercial power supply 13 in a normal state, and supplies power to the lighting circuit section 12 in an emergency.

The inspection switch 15 is a so-called internally illuminated push-button switch of a momentary operation type with a normally open contact, and as shown in FIG. 1, has a switch structure portion 15a and a light source 15b inside. . The push button 15c is formed of a transparent or translucent member, and the inspection switch 15 is attached to the housing 16 such that the push button 15c is exposed outside the housing 16 of the lighting device. Therefore, the light source 15b can be viewed from outside through the push button portion 15c.

The light source 15b is equivalent to a state display light source. The light source 15b keeps the first lighting state when the storage battery 14 has a good charge state, and the second light state when the charge state is bad. It is what becomes. More specifically, since the first state is a lighting state and the second state is a light-off state, the inspector can visually check that the light source inside the inspection switch 15 is off, and Charging failure.

When the inspection switch 15 is pressed, the lighting circuit unit 12 cuts off the power supply from the commercial power supply 13 and receives the power supply from the storage battery 14 to turn on the lamp 11. This operation makes it possible to check the emergency lighting of the lighting device.

In the lighting device configured as described above, the storage battery 1 is provided inside the check switch 15 for confirming the emergency lighting.
Since the light source 15b for displaying the charge state of No. 4 is built in, the number of components when assembling the lighting device can be reduced, and the reliability of the lighting device can be improved.
In addition, the appearance can be improved.

The light source according to the present embodiment displays the state of charge of the storage battery in two states, a first lighting state and a second lighting state, but is not limited to this. Instead, it may be one that can display further information.

That is, the light source 15b keeps the first lighting state if the charge state of the storage battery 14 is good, and enters the second light state if the charge state is bad, and the lamp 11 is in the state of lamp life. When it becomes, it becomes the third lighting state,
Further, the charge state of the storage battery 14 is poor and the lamp 11
When the lamp reaches the end of its lamp life, the lamp may enter the fourth lighting state. For example, if the light source 15b is a green monochromatic light emitting diode, the light source 15b is turned on in the first lighting state, is turned off in the second lighting state, and is 1H in the third lighting state.
It may be made to blink at the frequency of z and to blink at the frequency of 2 Hz in the fourth lighting state. In this case, the light source 15b
Means that when the lamp 11 reaches the end of its life, the light source 15b
It flashes at a frequency of 1 Hz, and when the storage battery 14 becomes poorly charged, the light source 15b is turned off. Further, assuming that the lamp 11 has reached the lamp life in addition to the charging failure, the light source 15b is
Flashes at the frequency of z. If both the lamp 11 and the storage battery 14 are normal, the light source 15b is turned on.

Also, for example, using a two-color light emitting diode of green as the first color and red as the second color for the light source 15b, the light source 15b emits green light in the first lighting state, and emits light in the second lighting state. To turn off, and to turn on green and red alternately in the third lighting state,
Red light may be used in the fourth lighting state. In this case, when the lamp 11 reaches the end of its life, the light source 15b alternately lights up in green and red, and when the storage battery 14 becomes poorly charged, the light source 15b is turned off. Further, if the lamp 11 has reached the end of its life in addition to the charging failure, the light source 15b is lit in red. If both the lamp 11 and the storage battery 14 are normal, the light source 15b is lit green.

By setting the lighting state of the light source 15b to three or more, it is possible to increase the information that can be displayed without increasing the number of components exposed from the housing 16 of the lighting device. .

In the above embodiment, the lighting device is described as an emergency lighting device.
However, the present invention is not limited to this, and the guide light 17 as shown in FIGS. 3 and 4 may be used. In the case of the guide light 17,
The lamp 11 is a cold-cathode discharge lamp, which is normally lit by power supply from the commercial power supply 13, and is lit by power supply from the storage battery 14 in an emergency when power supply from the commercial power supply is cut off. . Even in the case of the guide light 17, the number of components can be reduced and reliability can be improved by integrating the inspection switch and the light source 15b.
