The power supply unit 14 is electrically connected to an emergency power supply 18 and includes a power supply unit 19 that converts the power supplied from the emergency power supply 18 into predetermined lighting power and supplies the power to the light source 16 . Furthermore, when the power supply unit 14 is connected to a plurality of light sources 16 , power is supplied evenly to the connected light sources 16 .

The power supply unit 14 also includes an inspection unit 11 that inspects the emergency power supply 18 . The inspection unit 11 inspects whether the emergency power supply 18 is operating normally by detecting the voltage, current, discharge time, etc. of the power supplied from the emergency power supply 18 . Specifically, a predetermined voltage threshold is stored, and when the detected voltage of the emergency power supply 18 is out of the range of the threshold, it is determined that an abnormality has occurred in the emergency power supply 18 . Furthermore, the inspection unit 11 inspects whether each light source 16 is operating normally by detecting the voltage, current, energization time, etc. of the power supply supplied from the power supply unit 19 to the fireproof wire 15 . Specifically, when the voltage is checked, a predetermined voltage threshold value is stored, and if the voltage supplied to the light source 16 via the fire-resistant wire 15 is out of the range of the threshold value, the light source 16 is abnormal. determine that has occurred. In other words, the inspection unit 11 has a function of inspecting the appliance main body 13 having the emergency power supply 18 and the light source 16 . The inspection unit 11 also includes a display monitor (not shown) that displays inspection information. By displaying the inspection information on the display monitor, the inspection operator can easily obtain the inspection information. Specifically, the numerical value of the voltage supplied from the emergency power supply 18 and the numerical value of the voltage supplied from the power supply unit 19 to the fixture main body 13 are displayed. If the detection result is within the range of the threshold value, that is, if the voltage is normal, the character "normal" is displayed together with the voltage value. On the other hand, if the detection result is out of the threshold value, that is, if it is not normal, the character "abnormal" is displayed together with the voltage value.

The emergency power supply 18 is installed separately from the instrument main body 13 and the power supply section 14 . The emergency power supply 18 is electrically connected to the distribution board 20 and supplied with external power such as AC power from the distribution board 20 .

It has a terminal block 17 connected to the terminal block 17 .

The housing 6 is made of metal, for example, and has a cylindrical shape with one end open.

The light source 16 uses, for example, a semiconductor light emitting element such as a light emitting diode (LED) or a laser diode, or a light emitting module composed of an organic EL element (OLED) or the like, and is configured to emit white light. The light source 16 has a transparent glass or resin lens that controls the distribution of light emitted from the light emitting module. The light source 16 is installed on one end side of the housing 6 and emits light downward from the ceiling surface.

The decorative frame 7 is made of metal and has a circular shape, for example. The decorative frame 7 has a light source hole in the center through which the light source 16 is inserted, and is attached to one end side of the housing 6 .

The mounting fixing springs 7 are a pair of metal plate springs for holding the instrument main body 10 on the ceiling surface, and are provided in the housing 6 .

The terminal block 17 has insulating properties and is provided at the other end of the housing 6 of the instrument main body 13 . The terminal block 17 has a fire-resistant wire insertion hole (not shown) into which the fire-resistant wire 15 is inserted on one end side, and an in-appliance wiring insertion hole (not shown) into which the in-apparatus wiring connected to the light source 16 is inserted on the other end side. not shown).

The emergency lighting device 10 does not turn on because power is not supplied during normal times when external power is supplied from the distribution board 20 to the power supply unit 19 .

On the other hand, in an emergency or inspection, the supply of external power from the distribution board 20 to the power supply unit 19 is stopped, and power is supplied from the emergency power supply 18 to the power supply unit 19 . Here, when the emergency power supply 18 is a storage battery, DC power is supplied, and when it is a private power generator, AC power is supplied. The power supply unit 19 converts the power of the emergency power supply 18 into a predetermined emergency lighting power supply, and supplies this emergency lighting power supply to the light source 16 through the fireproof wire 15 , the terminal block 17 and the wire 43 in the fixture. The light sources 16 of the fixture bodies 13 to which the emergency lighting power supply is supplied light up, and emit light downward from the ceiling side. Furthermore, the inspection unit 11 detects the voltage of the power supply supplied from the emergency power supply 18 to the power supply unit 19 and the voltage of the power supply supplied from the power supply unit 19 to the light source 16 of the instrument main body 13, and displays inspection information on a display monitor. to display.

Next, the operation during inspection of the emergency lighting device 10 will be described.

FIG. 3 is a sequence diagram showing the flow of operations during inspection of the emergency lighting device 10. As shown in FIG.

Normally, an external power supply such as AC power is supplied from the distribution board 20 to the emergency power supply 18, and the emergency power supply 18 converts the supplied power into a charging power supply for charging (S1). When the power supplied from the distribution board 20 is cut off for inspection, the emergency power supply 18 detects that the power is cut off by the power cutoff detection unit (S2). The emergency power supply 18 that has detected that the power supply from the distribution board 20 has been cut off supplies the power charged by itself to the power supply unit 14 (S3). When power is supplied to the power supply unit 14 , the inspection unit 11 detects the voltage of the power supplied to the power supply unit 19 . Here, if the detection result is within the range of a predetermined threshold value, the inspection information is displayed on the display unit and the characters "Normal" are displayed. On the other hand, if the detection result is out of the range of the predetermined threshold value, the inspection information is displayed on the display unit and the characters "abnormal" are displayed (S4). Next, the power supply unit 19 converts the power supplied from the emergency power supply 18 into power for lighting the light source 16 , and supplies the power to the light source 16 via the refractory wire 15 . Specifically, the voltage is converted into a DC voltage for lighting the light source 16 (S5). Each fixture main body 13 to which power is supplied from the power supply unit 19 turns on the light source 16 (S6). Here, the inspection unit 11 detects the voltage of the power supplied from the power supply unit 19 to the light source 16 through the fireproof wire 15 and displays it on the display monitor. If the detection result is within the range of a predetermined threshold value, inspection information is displayed on the display unit and the characters "Normal" are displayed. On the other hand, if the detection result is out of the range of the predetermined threshold value, the inspection information is displayed on the display unit and the characters "abnormal" are displayed (S7).

In this manner, the inspection operator can obtain inspection information on the appliance main body 13 and the emergency power supply 18, which are separately installed, from the inspection unit 19, thereby facilitating the inspection work.
