DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that each of the embodiments described below shows one specific example of the present invention. The numerical values, shapes, materials, components, the arrangement and connection forms of the components, steps, and the order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. Furthermore, among the components in the following embodiments, components that are not described in an independent claim showing an embodiment according to one aspect of the present invention will be described as optional components. The embodiment of the present invention is not limited to the current independent claim, and may be expressed by other independent claims.

[0012] Note that each drawing is a schematic diagram and is not necessarily a precise illustration. In addition, in each drawing, the same reference numerals are used for substantially the same configurations, and duplicated explanations may be omitted or simplified.

[0013] (Embodiment 1) [Lighting equipment configuration] The configuration of the lighting device according to the first embodiment will be described with reference to FIGS. 1 to 3. FIG.

[0014] Fig. 1 is a diagram showing a schematic cross section of a lighting fixture body 10, a lighting fixture adaptor 20, and a communication module 30 which constitute a lighting device 1 according to embodiment 1. Fig. 2 is a block diagram of the lighting device 1.

[0015] 1 and 2 also show a remote controller 60 that communicates with the lighting fixture body 10, and a communication terminal 70 that communicates with the communication module 30. The remote controller 60 is a dedicated terminal that outputs an infrared signal IC1 for controlling the lighting of the lighting fixture body 10. The communication terminal 70 is a terminal that outputs a wireless signal R1 for controlling the lighting of the lighting fixture body 10, and is, for example, a smartphone or a tablet terminal. The remote controller 60 and the communication terminal 70, together with the lighting device 1, constitute a lighting system 2.

[0016] The lighting device 1 is installed on a construction material 3 such as the ceiling of a building. The lighting device 1 is, for example, a ceiling light fixed to the ceiling of a building, and irradiates illumination light into the interior space of the building. The lighting device 1 is installed on the ceiling by being connected to a ceiling hook body 50 fixed to the ceiling.

[0017] 1 and 2, the lighting device 1 includes a lighting fixture body 10, a lighting fixture adaptor 20, and a communication module 30. Below, the lighting fixture body 10, the lighting fixture adaptor 20, and the communication module 30 will be described in order.

[0018] The lighting fixture body 10 has a fixture power receiving unit 11, a light source 13, an infrared receiving unit 14, and a fixture control unit 15. The lighting fixture body 10 also has a fixture board 17, a fixture housing 16, and a light-transmitting cover 19.

[0019] The appliance power receiving unit 11, the infrared receiving unit 14, and the appliance control unit 15 are provided on an appliance board 17. The appliance board 17 is disposed inside a case-shaped appliance housing 16. The light source 13 is provided in the appliance housing 16 so as to be located on the interior space side of the building as viewed from the appliance housing 16. The light-transmitting cover 19 is attached to the appliance housing 16 so as to cover the light source 13, the appliance board 17, and a communication module 30 described later.

[0020] The appliance power receiving unit 11 is, for example, a plug connector provided at the tip of a cable drawn from the appliance board 17. The appliance power receiving unit 11 is connected to a power output unit 33 provided in the communication module 30. The appliance power receiving unit 11 receives AC power output from the communication module 30 and outputs the received AC power to the appliance control unit 15. In other words, the lighting appliance body 10 is driven based on the AC power output from the communication module 30.

[0021] The light source 13 is, for example, a light emitting module including a plurality of light emitting elements. The light source 13 emits light toward the interior space of the building.

[0022] The light-transmitting cover 19 has a light distribution control function that controls the distribution of light. The light-transmitting cover 19 transmits the light emitted by the light source 13 and emits it to the interior space of the building. The light-transmitting cover 19 also transmits the infrared signal ic1 output from the remote controller 60 so that the infrared signal ic1 reaches the infrared receiving unit 14. The light-transmitting cover 19 also reflects a part of the infrared signal ic2 output from the infrared transmitting unit 37 of the communication module 30 on the inner surface of the light-transmitting cover 19 and allows the part to reach the infrared receiving unit 14.

[0023] The infrared receiving unit 14 is a sensor that receives the infrared signals ic1 and ic2. The infrared receiving unit 14 is provided on the fixture board 17 so that the infrared light receiving axis of the infrared receiving unit 14 is along the light emission direction d1 of the lighting device 1. For example, the infrared receiving unit 14 is connected to the fixture board 17 so that the infrared light receiving axis is perpendicular to the floor of the building. A passing section 18 for passing the infrared signals ic1 and ic2 is provided at a position on the translucent cover 19 side as viewed from the infrared receiving unit 14. The passing section 18 is window frame-shaped and is formed on the board on which the light source 13 is mounted and on the lighting fixture body 10. The infrared receiving unit 14 receives the infrared signal ic1 transmitted from the remote controller 60, or the infrared signal ic2 transmitted from the infrared transmitting unit 37 of the communication module 30 and reflected by the translucent cover 19, via the passing section 18. The infrared receiving unit 14 outputs the received infrared signals ic1 and ic2 to the fixture control unit 15.

[0024] The appliance control unit 15 controls the turning on and off, dimming, and color adjustment of the light source 13 based on the infrared signals ic1 and ic2 received by the infrared receiving unit 14.

[0025] The lighting fixture adaptor 20 is an adaptor for connecting the lighting fixture main body 10 to a ceiling hook body 50 provided on a construction material 3 such as a ceiling.

[0026] The lighting fixture adapter 20 has a cylindrical adapter housing 26 and two adapter locking members 29 protruding from the side surfaces of the adapter housing 26. The two adapter locking members 29 are biased from the inside toward the outside of the adapter housing 26 by an elastic member (not shown) housed in the adapter housing 26. The lighting fixture adapter 20 supports the lighting fixture main body 10 by the adapter locking members 29 protruding from the side surfaces of the adapter housing 26.

[0027] Furthermore, the lighting device adapter 20 supplies AC power supplied from the outside via the ceiling hook body 50 to the communication module 30. The lighting device adapter 20 has adapter power receiving units 21a and 21b with an L-shaped cross section, and an adapter power supply unit 23 that is electrically connected to the adapter power receiving units 21a and 21b.

[0028] The adapter power receiving units 21a and 21b are terminals protruding from the upper surface of the adapter housing 26. The adapter power receiving units 21a and 21b are inserted into the ceiling hook body 50, and the lighting fixture adapter 20 is attached to the ceiling hook body 50, whereby the adapter power receiving units 21a and 21b are connected to a commercial power source.

[0029] Adapter power supply unit 23 is, for example, a receptacle connector provided inside adapter housing 26. Module power receiving unit 31 of communication module 30 is connected to adapter power supply unit 23, and adapter power supply unit 23 supplies AC power received by adapter power receiving units 21a and 21b to communication module 30.

[0030] The communication module 30 is attached to the lighting fixture body 10. The communication module 30 is also detachable from the lighting fixture body 10. This will be described later.

[0031] The communication module 30 has a module power receiving unit 31, a power supply unit 32, a power output unit 33, a wireless communication unit 34, a module control unit 35, and an infrared transmission unit 37. The communication module 30 also has a module housing 46 and a module board 47.

[0032] The module housing 46 is cylindrical and has an upper surface 46a and a lower surface 46b perpendicular to the light emission direction d1, and a side surface 46c connecting the upper surface 46a and the lower surface 46b. A module board 47 is disposed inside the module housing 46. The module board 47 is provided with a module power receiving unit 31, a power supply unit 32, a power output unit 33, a wireless communication unit 34, a module control unit 35, and an infrared transmission unit 37.

[0033] When the communication module 30 is attached to the lighting fixture body 10, the module power receiving unit 31 is electrically connected to the adapter power supply unit 23 and receives AC power supplied from the lighting fixture adapter 20. When the communication module 30 is not attached to the lighting fixture body 10, the module power receiving unit 31 is not electrically connected to the adapter power supply unit 23 and does not receive power.

[0034] The module power receiving unit 31 is, for example, a plug connector provided at the tip of a cable drawn from the module board 47. The plug connector of the module power receiving unit 31 has the same specifications as the plug connector of the fixture power receiving unit 11 of the lighting fixture main body 10, and has the same shape, number of terminals, etc. The module power receiving unit 31 is connected to the adapter power supply unit 23 of the lighting fixture adapter 20.

[0035] Module power receiving unit 31 outputs the received AC power to power supply unit 32. Module power receiving unit 31 also outputs the received AC power to lighting fixture main body 10 via power output unit 33. In other words, the AC power input to module power receiving unit 31 is branched on the wiring of module board 47, and output to each of power supply unit 32 and lighting fixture main body 10.

[0036] The power supply unit 32 converts the AC power received by the module power receiving unit 31 into DC power and outputs the DC power to the module control unit 35. That is, the communication module 30 is driven based on the AC power supplied from the lighting fixture adapter 20. The power supply unit 32 is, for example, an AC / DC converter.

[0037] The power output unit 33 outputs the AC power received by the module power receiving unit 31 to the lighting fixture body 10. The power output unit 33 is a receptacle connector provided on the module board 47. The receptacle connector of the power output unit 33 has the same specifications as the receptacle connector of the adapter power supply unit 23. The fixture power receiving unit 11 of the lighting fixture body 10 is connected to the power output unit 33. The power output unit 33 outputs the AC power supplied from the lighting fixture adapter 20 to the lighting fixture body 10. Note that the power output unit 33 of this embodiment outputs only AC power and does not output control signals for controlling the lighting fixture body 10 to the lighting fixture body 10.

[0038] The wireless communication unit 34 receives a wireless signal r1 transmitted from the communication terminal 70. Wireless communication is communication using radio waves, excluding visible light communication and infrared communication. The wireless communication unit 34 performs wireless communication based on a wireless communication standard such as Wi-Fi (registered trademark), Bluetooth (registered trademark), BLE, or ZigBee (registered trademark). The wireless signal r1 includes instruction information for controlling the lighting of the lighting fixture body 10, such as an instruction to turn on or off the light source 13, and an instruction to select a dimming ratio or color temperature (light color). The wireless signal r1 received by the wireless communication unit 34 is output to the module control unit 35.

[0039] The module control unit 35 includes a CPU, a ROM, a RAM, etc., and realizes various functions by loading a program stored in the ROM into the CPU. The ROM stores an infrared signal ic2 corresponding to the wireless signal r1. The control command of the infrared signal ic2 is the same as the control command of the infrared signal ic1 transmitted from the remote controller 60.

[0040] The module control unit 35 converts the wireless signal r1 received by the wireless communication unit 34 into an infrared signal ic2. The module control unit 35 also outputs the converted infrared signal ic2 to the infrared transmission unit 37.

[0041] The infrared transmitting unit 37 transmits the infrared signal ic2 converted by the module control unit 35 to the infrared receiving unit 14. The infrared transmitting unit 37 is, for example, an infrared LED, and is arranged so that the emission direction of the infrared signal ic2 is the same as the light emission direction d1. The infrared signal ic2 output from the infrared transmitting unit 37 travels toward the translucent cover 19, and a part of the infrared signal ic2 is reflected by the inner surface of the translucent cover 19 and reaches the infrared receiving unit 14 of the lighting fixture body 10. The infrared receiving unit 14 outputs the received infrared signal ic2 to the fixture control unit 15, and the fixture control unit 15 controls the lighting of the light source 13 based on the infrared signal ic2.

[0042] Fig. 3 is a diagram showing a state in which the communication module 30 is removed from the lighting fixture body 10. In Fig. 3, the light-transmitting cover 19 is also removed.

[0043] 3, the communications module 30 has two module locking portions 49 that are locked to the lighting fixture body 10. The module locking portions 49 protrude from a side surface 46c of the module housing 46, and are biased from the inside toward the outside of the module housing 46 by an elastic member (not shown) contained in the module housing 46.

[0044] The communications module 30 is attached to the lighting fixture body 10 by fitting the two module locking portions 49 into the annular groove 16b provided on the inner circumferential surface 16a of the fixture housing 16. The communications module 30 is removed from the fixture housing 16 by biasing the module locking portions 49 inward. This makes the communications module 30 detachable from the lighting fixture body 10.

[0045] In this way, in the lighting device 1 of this embodiment, by adding a simple configuration called a communication module 30 to the lighting fixture main body 10 that is controlled by an infrared signal, it is possible to make the lighting fixture main body 10 that is controlled by an infrared signal also controllable by a wireless signal r1.

[0046] [Lighting device operation] The operation of the lighting device 1 will now be described.

[0047] FIG. 4 is a flowchart showing the operation of the lighting device 1.

[0048] First, the wireless communication unit 34 of the communication module 30 receives the wireless signal r1 transmitted from the communication terminal 70 (step S11).

[0049] Next, the module control unit 35 of the communication module 30 converts the radio signal r1 received by the wireless communication unit 34 into an infrared signal ic2 (step S12).

[0050] Next, the infrared transmitter 37 of the communication module 30 outputs the converted infrared signal ic2 (step S13).

[0051] Next, the infrared receiving unit 14 of the lighting fixture body 10 receives the infrared signal ic2 output from the infrared transmitting unit 37 (step S14). Specifically, the infrared receiving unit 14 receives the infrared signal ic2 output from the infrared transmitting unit 37 and reflected by the inner surface of the translucent cover 19. Note that if the output of the infrared signal ic2 from the infrared transmitting unit 37 is strong, the infrared receiving unit 14 may receive the infrared signal ic2 that has passed through the translucent cover 19 and been reflected by the floor of the building.

[0052] Next, the fixture control unit 15 of the lighting fixture body 10 controls the lighting of the light source 13 based on the infrared signal ic2 received by the infrared receiving unit 14 (S15).

[0053] By performing steps S11 to S15, the lighting of the lighting fixture body 10, which is controlled by an infrared signal, can be easily controlled by the wireless signal r1.

[0054] [Modification of the first embodiment] A description will be given of a lighting device 1A according to a modification of embodiment 1. In this modification, an example will be described in which the emission direction of an infrared signal ic2 from an infrared transmitter 37A is different from the light emission direction d1.

[0055] FIG. 5 is a schematic cross-sectional view of an illumination device 1A according to a modified example of the first embodiment.

[0056] 5, the infrared transmitting unit 37A of the modified example is attached to the module substrate 47 via an attachment member 48. For example, the infrared transmitting unit 37A is disposed so that the emission direction of the infrared signal ic2 is perpendicular to the light emission direction d1. When viewed from the infrared receiving unit 14 side, the infrared receiving unit 14 is located within a conical region having an apex angle of 90° with respect to a center line cL1 along the direction in which the intensity of the infrared signal ic2 transmitted from the infrared transmitting unit 37A is the highest.

[0057] Although not shown, a bullet-shaped infrared LED with lead wires may be used for the infrared transmitter 37A, and the lead wires may be bent at approximately 90° for mounting, without using the mounting member 48. This allows the infrared receiver 14 to be positioned within a cone region having an apex angle of 90° with respect to the center line cL1 along the direction in which the intensity of the infrared signal ic2 is at its highest, as in the above case.

[0058] According to the above configuration, the infrared signal ic2 output from the infrared transmitting unit 37A can reach the infrared receiving unit 14 of the lighting fixture body 10 directly. Therefore, the infrared receiving unit 14 can receive the infrared signal ic2 without increasing the output intensity of the infrared signal ic2 from the infrared transmitting unit 37A more than necessary. This makes it possible to reduce the power consumption of the communication module 30 attached to the lighting fixture body 10.

[0059] In this configuration, in order to allow the infrared signal ic2 to be received efficiently by the infrared receiving unit 14, for example, a notch may be provided in the board on which the light source 13 is mounted and in the passage portion 18 of the lighting fixture body 10, or a cylindrical member (not shown) may be provided on the receiving side of the infrared receiving unit. This makes it possible to receive infrared rays that enter obliquely more efficiently. Also, a translucent cover that is integrated with the cover that covers the light source 13 may be provided on the infrared translucent portion of the board on which the light source 13 is mounted and the lighting fixture body 10.

[0060] (Embodiment 2) A description will be given of a lighting device 1B according to the second embodiment. In the second embodiment, an example in which a communication module 30 is provided inside a lighting fixture adaptor 20B will be described.

[0061] Fig. 6 is a diagram illustrating a schematic cross section of a lighting device 1B according to embodiment 2. Fig. 7 is a block configuration diagram of the lighting device 1B.

[0062] 6 and 7, the lighting device 1B of the second embodiment includes a lighting fixture body 10, a lighting fixture adaptor 20B, and a communication module 30. The lighting fixture body 10 is the same as that of the first embodiment.

[0063] In the second embodiment, the communication module 30 is provided in the adapter housing 26B of the lighting device adapter 20B and is integrated with the lighting device adapter 20B. Specifically, the housing of the communication module 30 shown in the first embodiment is included in and integrated with the adapter housing 26B. In the adapter housing 26B, the adapter power receiving units 21a, 21b and the adapter power supply unit 23 constituting the lighting device adapter 20B, as well as the module power receiving unit 31, the power supply unit 32, the power output unit 33, the wireless communication unit 34, the module control unit 35, the infrared transmission unit 37, and the module board 47 constituting the communication module 30 are provided.

[0064] In the lighting device 1B of the second embodiment, the communication module 30 is provided in the adapter housing 26B of the lighting fixture adapter 20B. In this way, in the lighting device 1B, by adding a simple configuration of the communication module 30 to the lighting fixture adapter 20B, the lighting fixture body 10, which is controlled by an infrared signal, can also be controlled by a wireless signal r1.

[0065] Another example of the lighting fixture adaptor 20B according to the second embodiment will be described below.

[0066] Fig. 8A is a schematic diagram showing another example of the lighting fixture adaptor 20B of the lighting device 1B. Fig. 8B is a schematic diagram showing yet another example of the lighting fixture adaptor 20B of the lighting device 1B.

[0067] As shown in Fig. 8A, the module board 47 of the lighting fixture adapter 20B may be arranged vertically instead of horizontally. As shown in Fig. 8B, the module power receiving unit 31 does not need to be a connector member. For example, the module power receiving unit 31 may be directly connected to the base of the adapter power receiving units 21a and 21b instead of to the adapter power supply unit 23. In that case, the lighting fixture adapter 20B may not be provided with the power output unit 33, and the fixture power receiving unit 11 may be connected to the adapter power supply unit 23.

[0068] (Embodiment 3) A lighting device 1C according to a third embodiment will be described. In the third embodiment, an example in which a communication module 30 is attached to a lighting fixture adaptor 20C will be described. In the third embodiment, an example in which power is supplied to a lighting fixture body 10 from the lighting fixture adaptor 20C will be described.

[0069] Fig. 9 is a diagram illustrating a schematic cross section of an illumination device 1C according to embodiment 3. Fig. 10 is a block configuration diagram of the illumination device 1C.

[0070] As shown in Figs. 9 and 10, a lighting device 1C according to the third embodiment includes a lighting fixture main body 10, a lighting fixture adaptor 20C, and a communications module 30C.

[0071] The lighting fixture body 10 has a lighting fixture adaptor 20C as a connection destination of the fixture power receiving unit 11, and the other configurations are the same as those of the first embodiment.

[0072] The fixture power receiving unit 11 is connected to the adapter power supply unit 23 provided in the lighting fixture adapter 20C. The fixture power receiving unit 11 receives AC power output from the adapter power supply unit 23 and outputs the received AC power to the fixture control unit 15. In other words, the lighting fixture main body 10 is driven based on the AC power output from the lighting fixture adapter 20C.

[0073] In order to supply AC power to communication module 30C, lighting device 1C of embodiment 3 has another power supply unit different from adapter power supply unit 23 and another power receiving unit different from module power receiving unit 31. Specifically, the other power supply units are provided on multiple protrusions 27a, 27b protruding from the bottom surface of adapter housing 26. More specifically, adapter power supply unit 23a is provided inside one protrusion 27a of the multiple protrusions 27a, 27b, and adapter power supply unit 23b is provided inside the other protrusion 27b.

[0074] The other power receiving units are module power receiving units 31a and 31b, which are provided in the communication module 30C. The module power receiving units 31a and 31b are, for example, metal terminals with a T-shaped cross section. The module power receiving unit 31a is connected to the adapter power supply unit 23a, and the module power receiving unit 31b is connected to the adapter power supply unit 23b. The module power receiving units 31a and 31b output the received AC power to the power supply unit 32. In other words, the communication module 30C is driven based on the AC power received by the module power receiving units 31a and 31b. Note that the module power receiving units 31a and 31b do not output the received AC power to the lighting fixture body 10.

[0075] Additionally, the module power receiving units 31a and 31b also have a locking function for mounting the communications module 30C on the lighting fixture adaptor 20C.

[0076] Fig. 11 is a diagram showing a state in which the communications module 30C is removed from the lighting fixture adaptor 20C. Fig. 11(a) shows the lighting fixture body 10, the lighting fixture adaptor 20C, and the communications module 30C, Fig. 11(b) shows an enlarged view of the protrusion 27b, and Fig. 11(c) shows a view of the protrusion 27b from the communications module 30C side.

[0077] 11(b) and 11(c), the other protrusion 27b is provided with a locking hole 28b into which the module power receiving unit 31b is inserted. The locking hole 28b is, for example, an arc-shaped long hole, and has a wide portion through which the module power receiving unit 31b can be inserted and a narrow portion that locks the module power receiving unit 31b. The other protrusion 27a is also provided with a locking hole 28a (not shown).

[0078] The communication module 30C is attached to the lighting fixture adapter 20C by inserting the module power receiving units 31a, 31b into the wide portions of the locking holes 28a, 28b and then rotating them in the direction of the narrow portions. This mounting operation electrically connects the module power receiving units 31a, 31b to the adapter power supply units 23a, 23b in a one-to-one correspondence. The communication module 30C is removed from the lighting fixture adapter 20C by rotating it in the opposite direction to the direction in which it was rotated during mounting. This removal operation electrically disconnects the module power receiving units 31a, 31b from the adapter power supply units 23a, 23b. This allows the communication module 30C to be freely attached to and detached from the lighting fixture adapter 20C.

[0079] In this way, in the lighting device 1C, by adding a simple configuration of the communications module 30C to the lighting fixture adapter 20C, it is possible to make the lighting fixture body 10, which is controlled by an infrared signal, also controllable by a wireless signal r1.

[0080] (summary) The lighting device 1 according to this embodiment includes a lighting fixture body 10 having a light source 13, an infrared receiving unit 14 that receives an infrared signal ic2, and a fixture control unit 15 that controls the light source 13 based on the infrared signal ic2 received by the infrared receiving unit 14, and a communication module 30 having a wireless communication unit 34 that receives a wireless signal r1, a module control unit 35 that converts the wireless signal r1 received by the wireless communication unit 34 into an infrared signal ic2, and an infrared transmission unit 37 that transmits the infrared signal ic2 converted by the module control unit 35 to the infrared receiving unit 14. The communication module 30 is detachable from the lighting fixture body 10.

[0081] In this way, by making the communication module 30 that performs wireless communication detachable from the lighting fixture body 10, the lighting fixture body 10 that is controlled by infrared signals can easily be made to be controllable by wireless signals r1 as well.

[0082] Furthermore, the communication module 30 may have a module power receiving unit 31 that receives AC power supplied from an external source.

[0083] According to this, the communication module 30 that performs wireless communication can be driven by AC power supplied from an external source. This makes it possible to make the lighting fixture body 10, which is controlled by an infrared signal, controllable by the wireless signal r1 as well.

[0084] Moreover, the lighting device 1 may further include a lighting fixture adapter 20 that supports the lighting fixture main body 10, and the lighting fixture adapter 20 may have an adapter power supply unit 23 that supplies AC power to the module power receiving unit 31.

[0085] According to this, the communication module 30 that performs wireless communication can be driven using AC power supplied by the lighting fixture adapter 20. This makes it possible to make the lighting fixture body 10, which is controlled by an infrared signal, controllable by the wireless signal r1 as well.

[0086] In addition, the module power receiving unit 31 may be configured to be electrically connected to the adapter power supply unit 23 when the communication module 30 is attached to the lighting fixture main body 10, and not to be electrically connected to the adapter power supply unit 23 when the communication module 30 is not attached to the lighting fixture main body 10.

[0087] According to this, the driving of the communication module 30 for wireless communication can be changed depending on whether the communication module 30 is attached to the lighting fixture body 10. This makes it possible to easily switch the lighting fixture body 10 from being controlled by an infrared signal to being controllable by the wireless signal r1 as well.

[0088] In addition, the lighting fixture adapter 20 may be connected to a ceiling hook body 50 provided in a building material, and may be supplied with AC power supplied from the ceiling hook body 50.

[0089] According to this, the communication module 30 that performs wireless communication can be driven using commercial AC power supplied from the ceiling hook body 50. This makes it possible to make the lighting fixture body 10, which is controlled by an infrared signal, controllable also by the wireless signal r1.

[0090] The communication module 30 may also have a power supply unit 32 that converts the AC power received by the module power receiving unit 31 into DC power and outputs the DC power to the module control unit 35, and a power output unit 33 that outputs the AC power received by the module power receiving unit 31 to the lighting fixture main body 10.

[0091] This allows the communication module 30, which performs wireless communication, and the lighting fixture body 10 to be driven using AC power. This allows the lighting fixture body 10, which is controlled by an infrared signal, to be controllable by a wireless signal r1 as well.

[0092] In addition, the communication module 30 may be operated based on the AC power received by the module power receiving unit 31 and output the AC power received by the module power receiving unit 31 to the lighting fixture main body 10, and the lighting fixture main body 10 may be operated based on the AC power output from the communication module 30.

[0093] In this way, by driving each of the communication module 30 and the lighting fixture body 10 using AC power, the lighting fixture body 10 that is controlled by an infrared signal can also be controlled by a wireless signal r1.

[0094] In addition, adapter power supply units 23a, 23b may supply AC power supplied from outside to each of the communication module 30C and the lighting fixture main body 10, and the communication module 30C may be driven based on the AC power received by the module power receiving units 31a, 31b, and the lighting fixture main body 10 may be driven based on the AC power supplied from the adapter power supply units 23a, 23b.

[0095] In this way, by driving each of the communications module 30C and the lighting fixture body 10 using AC power, the lighting fixture body 10 that is controlled by an infrared signal can also be controlled by a wireless signal r1.

[0096] In addition, the lighting device 1 further includes a translucent cover 19 that covers the lighting fixture body 10 and the communication module 30, and the infrared transmitting unit 37 outputs an infrared signal ic2 toward the translucent cover 19, the translucent cover 19 reflects the infrared signal ic2 output from the infrared transmitting unit 37, and the infrared receiving unit 14 receives the infrared signal ic2 reflected by the translucent cover 19.

[0097] In this way, by transmitting the infrared signal ic2 using the reflection of the light-transmitting cover 19, the infrared signal ic2 can reach the infrared receiving unit 14 without increasing the output intensity of the infrared signal ic2 from the infrared transmitting unit 37 more than necessary. This makes it possible to reduce the power consumption of the communication module 30 attached to the lighting fixture body 10.

[0098] Furthermore, the infrared receiving unit 14 may be located within a conical region having an apex angle of 90° with respect to a center line cL1 along the direction in which the intensity of the infrared signal ic2 transmitted from the infrared transmitting unit 37A is maximized.

[0099] This allows the infrared signal ic2 output from the infrared transmitting unit 37A to reach the infrared receiving unit 14 of the lighting fixture body 10 directly. Therefore, the infrared receiving unit 14 can receive the infrared signal ic2 without increasing the output intensity of the infrared signal ic2 from the infrared transmitting unit 37A more than necessary. This makes it possible to reduce the power consumption of the communication module 30 attached to the lighting fixture body 10.

[0100] In addition, the wireless communication unit 34 may receive a wireless signal r1 transmitted from the communication terminal 70, and the infrared receiving unit 14 may receive infrared signals ic1, ic2 transmitted from the remote controller 60 or the infrared transmitting unit 37.

[0101] With this, the lighting fixture body 10, which is controlled by an infrared signal, can be controlled by a wireless signal r1 transmitted from the communication terminal 70.

[0102] The lighting device 1B according to this embodiment includes a lighting fixture body 10 having a light source 13, an infrared receiving unit 14 that receives an infrared signal ic2, and a fixture control unit 15 that controls the light source 13 based on the infrared signal ic2 received by the infrared receiving unit 14, a communication module 30 having a wireless communication unit 34 that receives a wireless signal r1, a module control unit 35 that converts the wireless signal r1 received by the wireless communication unit 34 into an infrared signal ic2, and an infrared transmitting unit 37 that transmits the infrared signal ic2 converted by the module control unit 35 to the infrared receiving unit 14, and a lighting fixture adaptor 20B that supports the lighting fixture body 10. The communication module 30 is provided inside the lighting fixture adaptor 20B.

[0103] In this way, by providing the communication module 30 for wireless communication in the lighting fixture adapter 20B, the lighting fixture body 10 which is controlled by an infrared signal can be easily made controllable by a wireless signal r1 as well.

[0104] The lighting device 1C according to this embodiment includes a lighting fixture body 10 having a light source 13, an infrared receiving unit 14 that receives an infrared signal ic2, and a fixture control unit 15 that controls the light source 13 based on the infrared signal ic2 received by the infrared receiving unit 14, a communication module 30C having a wireless communication unit 34 that receives a wireless signal r1, a module control unit 35 that converts the wireless signal r1 received by the wireless communication unit 34 into an infrared signal ic2, and an infrared transmitting unit 37 that transmits the infrared signal ic2 converted by the module control unit 35 to the infrared receiving unit 14, and a lighting fixture adaptor 20C that supports the lighting fixture body 10. The communication module 30C is detachable from the lighting fixture adaptor 20C.

[0105] In this way, by making the communication module 30C that performs wireless communication detachable from the lighting fixture body 10, the lighting fixture body 10 that is controlled by infrared signals can easily be made controllable by wireless signals r1 as well.

[0106] Furthermore, the communications module 30C has module power receiving units 31a and 31b that are engaged with the lighting fixture adaptor 20C, and the module power receiving units 31a and 31b may receive AC power supplied from an external source.

[0107] This allows the communication module 30C to be detachable from the lighting fixture adapter 20C and to be driven by AC power supplied from an external source. This allows the lighting fixture body 10, which is controlled by an infrared signal, to be easily controlled by a wireless signal r1.
