FIG. 2 is a view showing a schematic configuration of the entire system of the lighting device according to the first embodiment. 3A is a transverse cross-sectional view showing a heat resistant wiring of the lighting device of the first embodiment. Fig. 3B is a plan view showing a heat-resistant wiring board of the lighting device of the first embodiment. 4 is a flow chart for explaining the operation of the illumination device of the first embodiment.

As shown in FIG. 2, the illuminating device of the present embodiment includes a ceiling-side structure 1 attached to a ceiling surface, and a lower structure 11 attached to a mounting surface different from a ceiling surface, for example, a lower portion of a side wall of a building.

The ceiling side structure 1 has, for example, a lamp 2 (hereinafter referred to as a high ceiling lamp) installed at a high ceiling of a gymnasium, a factory, a warehouse, a commercial facility, or the like. The high ceiling lamp 2 includes an arm (mounting portion) 4 that is attached to a ceiling surface of a high ceiling in a suspended state, and a light source 7 provided on the arm 4 and having a substrate on which a light-emitting element (not shown) is mounted and covered The light-transmitting cover member 7a of the substrate; and the lamp body 8 hold the light source 7. Here, as the light-emitting element (DC load), for example, a light emitting diode (LED) is used. At this time, the LED derives high illumination of illumination that can illuminate the illumination object from a height. The cover member 7a is formed of a heat resistant material such as glass. Further, the lamp body 8 is formed of a heat resistant material such as metal.

The lamp body 8 is a one side (the lower surface side in FIG. 1) of a rectangular flat plate (not shown), and a substrate on which a plurality of LED elements are mounted is disposed. On the other surface side of the board (the upper surface side in Fig. 1), a plurality of fins 9 are integrally provided. Further, the high ceiling lamp 2 of the present embodiment illuminates a wide range of spaces in the downward direction shown in FIGS. 1 and 2 by causing a plurality of LED elements mounted therein to emit light. Here, the light source 7 is provided with light distribution of a light intensity peak in the direction directly below the lamp 2. Further, the high ceiling light fixture 2 has a light distribution member that can illuminate the illumination object from a high place with illumination light from the high illumination LED. Further, the lamp body 8 has a wiring board 3. One end side of the heat-resistant wiring 5 is connected to the wiring board 3.

As shown in FIG. 3A, the heat-resistant wiring 5 is made of, for example, a fire-resistant cable which is formed by coating a heat-resistant heat-resistant sheath 5b around a core wire 5a such as a copper wire. The periphery of the heat-resistant sleeve 5b is covered with a vinyl resin 5c. The diameter of the heat-resistant sleeve 5b is larger than that of the core wire 5a of the conventional F cable. Therefore, as shown in FIG. 3B, the diameter of the wiring insertion hole 6 of the wiring board 3 is also larger than the diameter of the wiring insertion hole for the ordinary F cable. Further, it is preferable that the wiring board 3 is also a heat-resistant wiring board 3 having heat resistance. Thereby, the basic required function as a lighting fixture for emergency lighting is satisfied. In other words, it is a structure that can be maintained for 30 minutes in an environment with an ambient temperature of 140 °C.

The lower structure 11 includes an LED power source 12 as a power source for general lighting, a battery 14 such as a battery, and a unit 13 including a control unit. The other end side of the heat resistant wiring 5 is connected to the unit 13. The heat resistant wiring 5 is fixed to, for example, a wall surface of a building. The control unit of the unit 13 controls switching of the LED power source 12 and the battery 14. Further, in a normal state other than the power failure, the control unit of the unit 13 switches to a state in which the LED power source 12 is connected to the high ceiling lamp 2. At this time, the light source 7 of the high ceiling lamp 2 is used as a light source for usual lighting. Further, when the power supply from the external power source is stopped, the control unit of the unit 13 switches to the state in which the battery 14 is connected to the high ceiling lamp 2. At this time, the electric power used to use the light source 7 of the high ceiling lamp 2 as an emergency lighting for emergency lighting is supplied from the battery 14. Moreover, the light distribution of the light source 7 when the light source 7 of the high ceiling light fixture 2 is used as an emergency light is matched with the light distribution of the light source 7 at normal time.

As described above, in the present embodiment, as the power source of the LED of the high ceiling lamp 2, two systems of the LED power source 12 and the battery 14 are provided. The LED power source 12 and the battery 14 are switched and used by the control unit 13.

Specifically, the LED power source 12 is typically used, and is switched to the battery 14 during a power outage. The LED power supply 12 is connected to a system power supply that supplies commercial power, and converts an alternating current (AC) voltage into a direct current (DC) voltage. The battery 14 is a battery that is charged by the LED power source 12 via the unit 13.

The unit 13 performs lighting control of the LEDs of the high ceiling light fixture 2 based on a user instruction input from an operation panel or a wireless terminal (not shown) operated by a user (ordinary user or maintenance person). The unit 13 includes a wireless device for communicating with the wireless terminal, a control unit for performing control in response to a user's instruction input from the operation panel or the wireless terminal, and a display unit for displaying various kinds of information. The control unit includes, for example, an application specific integrated circuit (ASIC), a Field Programmable Gate Array (FPGA), or an integrated circuit such as a central processing unit (CPU). The operation of the control unit integrated circuit is performed in accordance with a program recorded in the recording device provided in the unit 13 or a program recorded in a recording area in the control unit integrated circuit. The display unit includes a small display device such as a liquid crystal display or an organic electroluminescence (EL) display. Further, the unit 13 also has a function of switching the battery 14 to the battery 14 at the time of power failure, as the operation power source of the unit. The switching of the operating power of the unit 13 itself may be switched by a software method by the control unit. However, it is preferable to forcibly switch by a hardware circuit.

Furthermore, it is preferable that the lower structure 11 is equipped with, for example, an inspection mechanism of the high ceiling lamp 2 or a monitor for displaying a battery abnormality of the battery 14 or the like.

Next, an example of the operational flow of the illumination device of the present embodiment will be described with reference to Fig. 4 . The flow of FIG. 4 is started by the operation of starting the power supply to the unit 13 from the LED power supply 12, and the program or the control recorded in the recording device provided in the control unit activation unit 13 of the unit 13 is controlled. The program recorded in the recording area in the partial circuit.

First, the control unit of the unit 13 monitors the power supply state from the system power supply to the LED power source 12, thereby determining whether or not power supply from the system power source to the LED power source 12 is blocked due to a local power failure or fire, etc., and a power failure occurs ( Act1). When it is determined that the power failure has not occurred, the control unit checks the amount of stored electricity (Act2) for charging the battery 14, and determines whether the battery is available or not based on whether or not the amount of stored electricity of the battery 14 is equal to or greater than a predetermined threshold amount of stored electricity (OK). ) (Act3). When it is determined that the battery is not available (NG), the control unit displays a warning of the battery 14 on the display unit in the unit 13 (Act4), and returns the operation to the Act1. According to the display of the battery warning, the user performs replacement of the battery 14 and the like.

Further, when it is determined in the Act 3 that the battery is available, the control unit determines whether or not there is an inspection instruction input from the operation panel or the wireless terminal (Act 5). Here, when it is determined that there is an inspection instruction input, the control unit performs an inspection operation corresponding to the inspection instruction input, and displays the result on the display unit (Act 6). Since the inspection operation and the result display are not directly related to the present embodiment, the description thereof will be omitted. Subsequently, the control unit returns to the action of Act1.

When it is determined that there is no inspection instruction input in the Act 5, the control unit determines whether or not the lighting switch (Switch, SW) of the high ceiling lamp 2 provided in the operation panel or the wireless terminal is in an ON state ( Act7). Here, if it is determined that the lighting SW of the high ceiling lamp 2 is not in an ON state, that is, it is determined to be in an OFF state, the high ceiling lamp 2 is turned off (Act 8). Subsequently, the control unit returns to the action of Act1. When it is determined that the lighting SW of the high ceiling lamp 2 is in an on state, the high ceiling lamp 2 is turned on (Act 9). At this time, the LED power source 12 is used as a driving power source for lighting to obtain high illumination. Subsequently, the control unit returns to the action of Act1.

On the other hand, when it is determined that the power failure has occurred in the Act 1, the control unit switches the driving power of the operating power source and the high ceiling lamp 2 from the LED power source 12 to the battery 14 (Act 10). Further, it is preferable that the operating power supply of the control unit itself is configured to be forcibly switched by a hardware circuit as described above. Further, the control unit lights the high ceiling lamp 2 as an emergency light (Act 11). At this time, the high ceiling lamp 2 is turned on using the battery 14 as a driving power source, so that the amount of light defined by the laws of various countries as the emergency light is obtained at the illumination target. Further, the lighting of the high ceiling lamp 2 as the emergency light does not depend on the state of the lighting SW, that is, even if the lighting SW is in the off state.

In addition, the threshold value of the battery available in the Act 3 is set to a value as follows, that is, the lighting of the high ceiling lamp 2 as the emergency light can satisfy at least the laws of various countries. The lighting time of the emergency light at the time of power failure, for example, 30 minutes.

When the high ceiling lamp 2 is turned on as an emergency light, the control unit determines whether or not the power failure due to a power failure in the area is restored (Act 12). Here, if it is determined that the power failure has not been restored, the control unit returns to the operation of Act11.

When the power failure has been restored, the control unit switches its own operating power source and the driving power of the high ceiling lamp 2 from the battery 14 to the LED power source 12 (Act 13). Subsequently, the control unit determines whether or not the lighting SW of the high ceiling lamp 2 provided in the operation panel or the wireless terminal or the like is in an on state (Act 14). Here, when the lighting SW of the high ceiling lamp 2 is off, the control unit turns off the high ceiling lamp 2 (Act 15), and then returns to the operation of Act1. Further, when the lighting SW of the high ceiling lamp 2 is in an ON state, the control unit lights the high ceiling lamp 2 (Act 16). At this time, lighting is performed to obtain illumination of higher illumination than when lighting as an emergency light. Subsequently, the control unit returns to the action of Act1.

Therefore, in the illuminating device of the present embodiment, the ceiling-side structure 1 is attached to the ceiling surface of the high ceiling, and the lower structure 11 is attached to a mounting surface different from the ceiling surface, for example, a lower portion of the side wall of the building. The lower structure 11 includes an LED power source 12 as a power source for general lighting, a battery 14 such as a battery, and a unit 13 including a control unit. Thereby, in a normal state other than the power failure, the control unit of the unit 13 switches to a state in which the LED power source 12 is connected to the high ceiling lamp 2. At this time, the light source 7 of the high ceiling lamp 2 is used as a light source for usual lighting.

Further, when the power supply from the external power source is stopped, the control unit of the unit 13 switches to the state in which the battery 14 is connected to the high ceiling lamp 2. At this time, the electric power used to use the light source 7 of the high ceiling lamp 2 as an emergency lighting for emergency lighting is supplied from the battery 14.

Therefore, in the present embodiment, the light source 7 of the high ceiling lamp 2 can be used as a common light source for lighting and an emergency light for emergency lighting. Therefore, it is not necessary to incorporate a battery such as a battery used as an emergency light in the high ceiling lamp 2. 14. Therefore, the weight reduction of the high ceiling luminaire 2 can be achieved, and the work of arranging the high ceiling luminaire 2 on the high ceiling can be simplified. Further, in the present embodiment, there is also an effect that it is not necessary to separately provide a dedicated emergency lamp other than the high ceiling lamp 2 on the high ceiling.

Moreover, since the battery 14 for emergency lighting can be provided in the lower structure 11 which is disposed below the ceiling surface of the high ceiling, it is not necessary to replace the battery 14 on the ceiling surface of the high ceiling. Further, in the lower structure 11 , for example, an inspection mechanism equipped with the high ceiling lamp 2 or a display monitor for displaying an abnormality of the battery of the battery 14 can perform the high ceiling lamp 2 around the lower structure 11 . Check the operation or replacement of the battery 14 and the like. Therefore, work at a high place around the ceiling side structure 1 provided in the high ceiling can be reduced, so that workability can be improved.

In the present embodiment, when a plurality of high ceiling lamps 2 are used as emergency lights, all of the plurality of high ceiling lamps 2 can be controlled by using only one unit 13 of the lower structure 11. Therefore, it is not necessary to perform the replacement work of the battery 14 on the ceiling surface of the high ceiling, so that the work can be simplified. Further, since all of the plurality of high ceiling lamps 2 can be collectively managed around the lower structure 11, the inspection work of the high ceiling lamp 2 or the replacement work of the battery 14 can be reduced to the periphery of the ceiling side structure 1. Work at home. Therefore, their workability can be improved.
