[Embodiment]
[Structure of lighting device]
First, the structure of the illumination device 10 will be described. FIG. 1 is a perspective view of a lighting device 10 according to the embodiment. The lighting device 10 is an emergency lighting device. An emergency lighting device (emergency lamp) is a lighting device that is turned on when power supply from an external power supply is stopped.

  The lighting device 10 is an embedded lighting device embedded in a wall or a ceiling. The lighting device 10 of this embodiment is used by being embedded in a hole formed in a ceiling board. The lighting device 10 has mounting springs 171 and 172, and is fixed to the ceiling by the pressing force of these springs. The illustrated illumination device 10 is merely an example. The lighting device 10 is not necessarily an embedded lighting device. For example, the lighting device 10 may be a hanging type lighting device.

  FIG. 2 is a bottom view of the lighting device 10. In the following description, an orthogonal coordinate system including the X axis, the Y axis, and the Z axis is used. In the figure, the direction indicated by the arrow is the plus direction. In the case of this embodiment, the X axis and the Y axis have an axial direction in the horizontal direction, and the Z axis has an axial direction in the direction of the vertical line. The axial direction of the X axis is parallel to the AA line shown in FIG. Note that the X-axis direction, the Y-axis direction, and the Z-axis direction shown in the following description are based on the premise that the light emitting direction of the illumination device 10 is a downward direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are appropriately read according to the installation form of the illumination device 10. For example, if the light emission direction is horizontal, the Z-axis direction is also horizontal.

  As illustrated in FIG. 2, the illumination device 10 includes a connection unit 11 and a light source 13. FIG. 3 is a view in which the lid 16 is removed from the illumination device 10 shown in FIG. The lighting device 10 includes a housing 12, a battery 14, and a lighting unit 15 in addition to the above configuration. The lighting device 10 can be retrofitted with a module 20. The module 20 can also be regarded as a part of the lighting device 10. Of course, the portion of the lighting device 10 excluding the module 20 may be regarded as the lighting device 10.

  The connection unit 11 is a terminal block in which terminals for connecting various cables for operating the lighting device 10 are arranged. The connection portion 11 is in a state of protruding from the housing 12 in a direction perpendicular to the Z-axis direction (in the present embodiment, the horizontal direction).

  The housing 12 is a bottomed cylindrical body with one bottom surface opened. In the illustrated example, the shape of the housing 12 is cylindrical, but the shape of the housing 12 is not limited to the cylindrical shape. For example, the shape of the housing 12 may be a rectangular tube shape or a hemispherical shape. The housing 12 is made of a hard material. For example, the housing 12 is formed of a metal such as iron or aluminum, or a hard resin such as hard vinyl chloride. The housing 12 is a portion that is embedded in the ceiling when the lighting device 10 is installed and is not visible to the user. A flange is provided on the periphery of the opening of the housing 12. When the lighting device 10 is installed, this flange prevents the lighting device 10 from being completely buried in the back of the ceiling by being caught on the ceiling plate (the outer peripheral portion of the hole formed in the ceiling plate). The housing 12 opens toward the direction in which the light source 13 emits light (hereinafter referred to as the light emitting direction). Since the illumination device 10 of the present embodiment emits light downward from the ceiling, the light emission direction is downward (Z-axis minus direction). The opening of the housing 12 is covered with a lid 16.

  FIG. 4 is a bottom view of the lid 16. The lid 16 is a plate-shaped decorative frame. The lid 16 is a portion exposed from the ceiling when the lighting device 10 is installed. The lid 16 is slightly larger than the bottom of the housing 12 so as to cover the housing 12. In the example of FIG. 4, the shape of the lid 16 is a disc shape, but the shape of the lid 16 is not limited to the disc shape. For example, the shape of the lid 16 may be an ellipse or a polygon (for example, a triangle, a quadrangle, or a hexagon). The lid 16 is made of a hard material. For example, the lid 16 is formed of a metal such as iron or aluminum, or a hard resin such as hard vinyl chloride.

  The cover 16 is formed with three through holes 161 to 163. The through hole 161 is a window for the light source 13. The through hole 161 is provided in the center of the lid 16. The through hole 162 is a window for inserting the module 20. The through-hole 162 is provided at a position facing a connection terminal 156 described later when the lid 16 is installed in the housing 12. The through hole 163 is a window used by the user for operating the lighting device 10. The through-hole 163 is provided at a position facing a later-described operation unit 154 and a later-described output unit 155 (lamps 155a and 155b) when the lid 16 is installed in the housing 12. The through hole 162 will be described in detail later.

  5 is a cross-sectional view taken along line AA in FIG. The lighting device 10 shown in FIG. 5 is in a state where the module 20 is removed. In FIG. 5, the attachment spring 172 is not shown. A battery 14 and a lighting unit 15 are stored in the housing 12. The battery 14 and the lighting unit 15 are components (ASSY) constituting the lighting device 10. A light source 13 is disposed on the surface of the lighting unit 15 on the light emission direction side (Z-axis minus direction side). In the example of FIG. 5, the light source 13 is located at the center of the reflection plate 131 disposed at the approximate center of the opening of the housing 12. The light source 13 is, for example, an LED (Light Emitting Diode).

  A circular through hole 161 is formed in the lid 16 according to the position of the light source 13. In the present embodiment, the light source 13 emits light downward from the through hole 161. The irradiation angle R1 of the light source 13 is, for example, 60 degrees. The irradiation angle R1 may be a beam angle (for example, a 1/2 beam angle) or a light distribution angle (for example, a 1/2 light distribution angle). Of course, the irradiation angle R1 of the light source 13 is not limited to 60 degrees. The irradiation angle R1 of the light source 13 may be an angle in the range of 10 to 180 degrees, for example.

  The battery 14 is a secondary battery such as a lithium ion battery. The battery 14 of the present embodiment is a battery module that can be attached to and detached from the inside of the housing 12. As shown in FIG. 3, the battery 14 is arranged in one region obtained by dividing the interior of the housing 12 into approximately two parts in a direction perpendicular to the light emitting direction (in the present embodiment, the horizontal direction). In addition, dividing the space into two in the horizontal direction means that two spaces are arranged in the horizontal direction. The user can insert and remove the battery 14 from the opening of the housing 12 without removing the lighting unit 15 from the housing 12.

  The lighting unit 15 is a power supply device that performs a lighting operation of the light source 13 and a charging / discharging operation of the battery 14. The lighting unit 15 is connected to an external power source and the battery 14, and performs a lighting operation of the light source 13 and a charge / discharge operation for the battery 14. The battery 14 is charged by the lighting unit 15. As shown in FIG. 3, the lighting unit 15 includes one area (an area in which the battery 14 is disposed) that is substantially divided into two in the direction perpendicular to the light emission direction (the horizontal direction in the present embodiment). The other area of the As shown in FIG. 3, an operation unit 154, an output unit 155, and a connection terminal 156 are arranged on the surface of the lighting unit 15 on the light emission direction side (in the present embodiment, the Z-axis minus direction side). ing.

  The operation unit 154 is a switch for the user to operate the lighting device 10. The operation unit 154 may be a button switch, a rocker switch, or a toggle switch. The type of switch is arbitrary. As described above, the through hole 161 is formed at a position of the lid 16 facing the operation portion 154. Therefore, the user can access the operation unit 154 without removing the lid 16 from the lighting device 10.

  The output unit 155 is an output device for the user to monitor the state of the lighting device 10. The output unit 155 includes a lamp 155a and a lamp 155b. The lamps 155a and 155b are, for example, LED lamps. As described above, the through hole 163 is formed at a position of the lid 16 facing the lamps 155a and 155b. The user can observe the light emission state of the lamps 155a and 155b through the through hole 163.

  The connection terminal 156 is a connector for connecting an external device for connecting the module 20 to the lighting device 10. The connection terminal 156 is disposed in the housing 12 so as to face the opening of the housing 12 on the end side of the lighting unit 15. Specifically, the connection terminal 156 is disposed on the surface (light emission direction side) facing the lid 16 of the lighting unit 15. The connection terminal 156 is, for example, a USB (Universal Serial Bus) terminal. The end surface on the light emission direction side of the connection terminal 156 is located on the inner side of the lid 16 (Z-axis plus direction side) or on the extension of the light emission direction side surface of the lid 16. Therefore, the connection terminal 156 does not protrude from the lid 16 and is hidden inside the lighting device 10 when the lighting device 10 is viewed from the X-axis and Y-axis directions (horizontal direction in the present embodiment). ing.

  As shown in FIG. 4, a through hole 162 is formed at a position facing the connection terminal 156 of the lid 16. Through the through-hole 162, the module 20 can be inserted into the connection terminal 156 from the outside of the lid 16. The shape of the through hole 162 is a circle, an ellipse, or a polygon (for example, a quadrangle). Of course, the shape of the through hole 162 may be other than these shapes. In the case of this embodiment, the through-hole 162 is a quadrangle.

  The through-hole 162 has a size and a position where the connection terminal 156 is accommodated when the lighting device 10 is viewed from the light emission direction (Z-axis minus direction). When the illumination device 10 is viewed from the light emitting direction side, the vertical width w3 of the through hole 162 in the drawing is larger than the vertical width w1 of the connection terminal 156. In addition, the width w4 in the horizontal direction of the through hole 162 is larger than the width w2 in the horizontal direction of the connection terminal 156. Between the outer edge of the connection terminal 156 and the edge of the through-hole 162, gaps m1 to m4 having a preset size are formed when viewed from the light emission direction so that the user can insert and remove the module 20 without difficulty. . The gaps m1 and m2 are gaps formed at the top and bottom of the connection terminal 156 in the drawing, and the gaps m3 and m4 are gaps formed at the left and right of the connection terminal 156 in the drawing. The gaps m1 to m4 each have a width in the range of 1 mm to 10 mm. Of course, the gaps m1 to m4 may be larger or smaller than this width.

  The module 20 is a communication module that communicates with an external device in accordance with a wireless communication standard such as a wireless local area network (LAN) or Bluetooth (registered trademark). The module 20 may be a small module called a dongle. The module 20 is used by being connected to the connection terminal 156. FIG. 6 is a diagram illustrating a state in which the module 20 is connected to the connection terminal 156. The module 20 is inserted into the connection terminal 156 from the outer side (light emission direction side) of the lid 16 through the through hole 162. The shape of the module 20 is substantially rectangular. The length L in the insertion direction (Z-axis direction) of the module 20 is a length determined in advance by the manufacturer or standard of the lighting device 10. For example, the length L is 1 cm to 10 cm. When the module 20 is connected to the connection terminal 156, a part of the module 20 protrudes outside the lid 16 (Z-axis minus direction side). Since the portion protrudes, the user can easily grasp the module 20 when removing the module 20 from the connection terminal 156.

  The connection terminal 156 is disposed at a position separated from the light source 13 by a distance d. The distance d is determined so that the protruding portion of the module 20 is positioned outside the irradiation angle R1 of the light source 13 when the length L of the module 20 is the maximum length allowed by the manufacturer or the standard. It is done. As a result, the module 20 does not fall within the range of the irradiation angle R1, so that the light from the light source 13 is not largely blocked by the module 20. Even if the module 20 is mounted, the lighting device 10 can prevent a large shadow of the module 20 from being generated on the irradiation surface.

[Configuration of lighting device]
Next, the structure of the illuminating device 10 is demonstrated, referring a block diagram. FIG. 7 is a diagram illustrating a configuration example of the illumination device 10 according to the embodiment. The lighting device 10 operates by receiving power supply from the external power supply 2. The external power source 2 is, for example, a commercial system power source. The external power source 2 may be a generator or a transformer arranged in a building or site. As described above, the lighting device 10 includes the connection unit 11, the light source 13, the battery 14, the lighting unit 15, and the module 20.

  The connection part 11 is a terminal block on which terminals for connecting various cables are arranged. The connection unit 11 is provided with a power supply terminal for connecting a power cable. The connection unit 11 is connected to an internal circuit of the lighting device 10. The connection unit 11 receives power from the external power source 2 via the power cable and supplies the power to the lighting unit 15 of the lighting device 10.

  The light source 13 is an emergency or guidance light source. The light source 13 is, for example, an LED (Light Emitting Diode). The light source 13 may be a light source other than an LED, such as a heat generating bulb, a fluorescent lamp, or a halogen lamp.

  The battery 14 is a secondary battery such as a lead storage battery, a nickel cadmium storage battery, a nickel hydrogen battery, or a lithium ion battery. When power supply from the external power supply 2 is stopped (that is, in an emergency), the battery 14 supplies power to the lighting unit 15. Further, when there is power supply from the external power source 2 (that is, during normal times), the battery 14 is charged by the lighting unit 15.

  The lighting unit 15 is a power supply device that performs a lighting operation of the light source 13 and a charging / discharging operation of the battery 14. The lighting unit 15 includes a power supply circuit 151, a control unit 152, a storage unit 153, an operation unit 154, an output unit 155, and a connection terminal 156.

  The power supply circuit 151 includes a switching circuit, an AC-DC converter, and the like. The switching circuit switches the power source of the power supplied to the light source 13 to either the external power source 2 or the battery 14. The AC-DC converter converts AC power supplied from the external power supply 2 into DC power. If the external power supply 2 is a DC power supply, the power supply circuit 151 may have a DC-DC converter instead of the AC-DC converter. The power supply circuit 151 operates based on the control of the control unit 152. The power supply circuit 151 has a sensor 151a inside. The sensor 151 a is a sensor that detects the storage state of the battery 14. Alternatively, the sensor 151 a is a sensor that detects the amount of current flowing through the light source 13. The sensor 151a may be a voltmeter or an ammeter. The sensor 151 a detects the storage state of the battery 14 or the light emission state of the light source 13 and notifies the control unit 152 of it.

  The control unit 152 is a controller that controls each unit of the lighting device 10. The control unit 152 may be a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit), or an integrated circuit such as an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit). Also good. The control unit 152 implements various processes by operating according to a program stored in the storage unit 153.

  The storage unit 153 is a storage device such as a dynamic random access memory (DRAM), a static random access memory (SRAM), or a flash memory. The storage unit 153 stores a program for operating the control unit 152 and the like. The storage unit 153 may record an operation history (log) of the lighting device 10.

  The operation unit 154 is a switch for the user to operate the lighting device 10. For example, the operation unit 154 is an inspection switch used when the user inspects the lighting device 10. When the user operates the operation unit 154 (for example, when the switch is turned on), the control unit 152 performs an inspection operation of the lighting device 10. The inspection operation is an operation for testing whether or not the lighting device 10 operates normally even in an emergency. More specifically, in the inspection operation, even when the power supply from the external power source 2 is cut off, the lighting device 10 is lit at a predetermined illuminance for a predetermined time (for example, 30 minutes) defined by law. This is an operation for testing whether or not it can continue. When the operation unit 154 is operated, the control unit 152 switches the power source of the light source 13 from the external power source 2 to the battery 14, and changes the amount of electricity stored in the battery 14 or the amount of current supplied to the light source 13 using an internal sensor or the like. Use to monitor. The control unit 152 outputs the inspection result (test result) to the output unit 155.

  The output unit 155 is a light emitting device such as an LED lamp, or a sound generator such as a speaker or a buzzer. The output unit 155 includes a lamp 155a and a lamp 155b. The lamp 155 a is a charge monitoring lamp for monitoring the state of the battery 14. The lamp 155 b is a lamp monitor lamp for monitoring the state of the light source 13. The control unit 152 of the lighting unit 15 turns on, turns off, or blinks the lamp 155a according to the charge amount of the battery 14 or the like. Further, the control unit 152 turns on, turns off, or blinks the lamp 155b according to the connection state of the light source 13 (for example, whether or not the LED cannot be energized due to disconnection or the like). Note that the lamps 155a and 155b also function as lamps for outputting the current operating state of the lighting device 10, the result of the checking operation, or the like while the lighting device 10 is in the checking operation.

  The connection terminal 156 is a connector for connecting an external device. The connection terminal 156 is, for example, a USB terminal, an IEEE (The Institute of Electrical and Electronic Engineers) 1394 terminal, or a Lightning (registered trademark) terminal. Of course, the connection terminal 156 may be a connector other than these. For example, the connection terminal 156 may be a connector with a unique standard uniquely determined by the manufacturer of the lighting device 10 or a connector with a standard other than the above. The connection terminal 156 is directly or indirectly connected to the control unit 152 of the lighting unit 15. When the module 20 is connected to the connection terminal 156, the connection terminal 156 allows the module 20 and the control unit 152 to communicate with each other. The connection terminal 156 may be configured to be able to supply power from the external power source 2 or the battery 14 to the module 20.

  The module 20 is a communication module that wirelessly communicates with an external device. The module 20 provides a wireless communication function to the lighting device 10. The module 20 may include a sensor such as an infrared sensor (human sensor). In this case, the module 20 can be restated as a sensor module. FIG. 8 is a diagram illustrating a configuration example of the module 20 according to the embodiment. The module 20 includes a communication unit 21, a sensor 22, a control unit 23, a storage unit 24, and a connection terminal 25.

  The communication unit 21 is a wireless communication interface that performs wireless communication with an external device. The communication unit 21 communicates with an external device in accordance with a wireless communication standard such as a wireless LAN (IEEE802.11), Bluetooth (registered trademark), or ZigBee (registered trademark).

  The sensor 22 is a sensor such as an infrared sensor (human sensor), a temperature sensor, or an illuminance sensor (brightness sensor). The sensor 22 may be a smoke sensor that detects smoke or a gas sensor that detects gas leakage. The sensor 22 detects the surrounding state of the lighting device 10 and notifies the control unit 23 of it.

  The control unit 23 is a controller that controls each unit of the module 20. The control unit 23 may be a processor such as a CPU or MPU, or may be an integrated circuit such as an FPGA or ASIC. The control unit 23 implements various processes by operating according to a program stored in the storage unit 24. For example, the control unit 23 communicates with the control unit 152 of the lighting device 10 via the connection terminal 25 and the connection terminal 156. Note that the control unit 23 may be configured to control each unit of the lighting device 10 via the control unit 152 of the lighting device 10.

  The storage unit 24 is a storage device such as a DRAM, SRAM, or flash memory. The storage unit 24 stores a program for operating the control unit 23 and the like.

  The connection terminal 25 is a connector connected to the connection terminal 156 of the lighting device 10. If the connection terminal 156 is a USB terminal, the connection terminal 25 is also a USB terminal. By connecting the connection terminal 25 to the connection terminal 156, the control unit 152 of the lighting device 10 can communicate with the control unit 23 of the module 20. The control unit 152 of the lighting device 10 communicates with an external device via the module 20. For example, the control unit 152 transmits a test log to the terminal device used by the user via the module 20.

  Note that the control unit 152 of the lighting device 10 may control each unit of the lighting device 10 based on the detection result of the sensor 22 received from the control unit 23. For example, if the sensor 22 is a human sensor, the control unit 152 may control the brightness of the light source 13 based on the detection result of the presence / absence of a person received from the control unit 23. It is also possible for the control unit 23 itself to control the brightness of the light source 13 via the control unit 152.

  According to the present embodiment, the through hole 162 into which the module 20 can be inserted from the outside of the lid 16 is provided at a portion facing the connection terminal 156 of the lid 16. Therefore, the user can attach / detach the module 20 to / from the connection terminal 156 without removing the lid 16. As a result, the user can easily attach and detach the module 20.

  Further, the connection terminal 156 is separated from the light source 13 by a distance d so that when the module 20 is connected, a portion protruding outside the cover 16 of the module 20 is located outside the irradiation angle R1 of the light source 13. Placed in position. Since the module 20 does not fall within the range of the irradiation angle R1, the light from the light source 13 is not largely blocked by the module 20. The lighting device 10 can maintain a predetermined brightness (for example, illuminance determined by law) even when the module 20 is mounted. Further, when the module 20 is, for example, a brightness sensor, the module 20 is not easily affected by the light source 13, and malfunction is less likely to occur.

  The module 20 is a wireless communication module. Even if the lighting device 10 does not have a wireless communication function, the lighting device 10 can have a wireless communication function. By changing the module 20, the lighting device 10 can cope with wireless communication of different standards. For example, assume that the module 20 is a wireless communication module compatible with a wireless LAN. When the user replaces the module 20 with a wireless communication module compatible with Bluetooth (registered trademark), the lighting device 10 can perform wireless communication using Bluetooth (registered trademark). Even when a new communication standard appears, it can be handled by replacing the module 20.

  The module 20 has a function as a sensor module. The lighting device 10 can have various sensor functions. The illuminating device 10 can change control according to the detection result of a sensor. For example, it is assumed that the module 20 has a human sensor. The lighting device 10 can brighten or darken the light source 13 according to the presence or absence of a person detected by a human sensor. As a result, the lighting device 10 can suppress power consumption and can continue to emit light for a longer time in an emergency.
