It is installed in places where many people come and go.

An example of such a lighting fixture conventionally used is the fourth.
Description will be made using the guide light fixture shown in the figure.

Reference numeral 1 denotes an appliance frame, which is formed in a substantially rectangular parallelepiped box shape having an opening 2 on the front surface, and a guide display panel 3 is detachably mounted on the opening 2 on the front surface.
A pair of lamp sockets (not shown) is attached to the left and right side surfaces of the instrument frame 1 at substantially the center in the vertical direction, and a straight tube fluorescent lamp 5 having filaments provided at both ends 4 is mounted on the lamp socket. The guide display panel 3 is horizontally and detachably mounted substantially at the center of the display panel 3.

An AC lighting device 6 that is electrically connected to a commercial AC power supply and supplies power to the straight tube-type fluorescent lamp 5 at normal times is provided on the upper right side of the fixture frame 1. Further, a storage battery 7 serving as an emergency power source is disposed on the lower side of the instrument frame 1, and the storage battery 7 is normally charged on the left side and converted to AC in an emergency to convert it into a straight tube fluorescent lamp. A DC lighting device 8 for supplying the DC lighting device 5 is provided. In addition, a lamp light extraction hole 9 for illuminating the floor surface is provided on the lower side surface of the instrument frame 1.

Then, in normal times, that is, when a fire or the like has not occurred, a fire signal voltage from a fire alarm (not shown) becomes energized, and a relay (not shown) is also excited to switch the relay contact to one side. As a result, the straight tube type fluorescent lamp 5 is always turned on by the commercial AC power supply, and the guide display panel 3 mounted on the fixture frame 1 is transmitted and illuminated to perform the guide display and the storage battery 7 serving as an emergency power supply.
Is charged by a commercial power supply via a charging circuit.

On the other hand, in an emergency such as a fire, for example, the relay contact is switched to the other by the fire signal voltage regardless of whether or not the commercial AC power is supplied. As a result, a DC power source using the storage battery 7 as a power source is converted into an AC power source by the DC lighting device 8 and supplied to the straight tube fluorescent lamp 5. In this way, the straight tube type fluorescent lamp 5 is turned on even in an emergency, and guidance display is performed.

And the like, and furthermore, it is necessary to provide a certain space between the guide display panel 3 to improve the heat radiation of these devices. There is a problem that can not be.

In addition, since the brightness of the straight tube type fluorescent lamp 5 at both ends 4 where the lamp filament is provided is lower than other portions, when the thickness of the guide lamp device is reduced, dark portions at both ends of the guide display panel 3 are formed. There was also a problem that it would exist.

Further, in the conventional guide light fixture, the guide display panel 3 facing the straight tube type fluorescent lamp 5 is subjected to light control processing so that the upper and lower portions of the guide display panel 3 have the same brightness. There is a problem in that the illuminance on the floor surface is low because there is a certain distance between the lamp light extraction hole 9 provided on the lower side surface portion 1 and the lamp light extraction hole 9.

Therefore, the present invention is intended to solve such a problem, and it is possible to reduce the thickness of a lighting fixture and to eliminate the presence of a part of a guide display panel having a spot-like high brightness. It is intended to provide a device.
