In this case, for example, a plurality of LED or organic EL elements can be assembled into a holder having an appropriate shape or the like, and used as a unit such as a rod, ring, or plane. It is also possible to form a bar, ring, plane or the like using one LED or organic EL element.
[0030]
As a light source, a case where only an LED is used, a case where only an organic EL is used, or a case where an appropriate number of LEDs and organic ELs are used in combination may be used.
[0031]
As the LED or the organic EL, a white one or another color can be used, and a plurality of colors of the LED and the organic EL can be mixed. Further, a cold cathode fluorescent lamp can be used as a light source of a power failure lamp in combination with an LED or an organic EL.
[0032]
Needless to say, as a means for lighting the LED or the organic EL, a drive control device generally used conventionally is used.
[0033]
In the above embodiment, the secondary battery is used as a power source for turning on the power failure lamp. However, a power storage device such as a capacitor may be used.
