MODE FOR CARRYING OUT THE INVENTION

[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. The following embodiments are examples embodying the present disclosure and are not intended to limit the technical scope of the present disclosure.

[0011] (Embodiment 1) [1] Overview First, an overview of the electric device 1 according to the present embodiment will be described with reference to FIGS. 1 and 2.

[0012] In the present embodiment, for convenience of explanation, based on the direction in the state where the electric device 1 is attached to the lighting fixture main body 100 (see the lower part of FIG. 2), the vertical direction at that time is defined as the vertical direction D1. Further, the front side of the electric device 1 is defined as the front, the back side as the rear, and the left-right direction D3 is defined based on the direction when the electric device 1 is viewed from the front. However, these directions are not intended to limit the usage direction (direction during use) of the electric device 1.

[0013] As shown in FIG. 1, the electric device 1 includes a device main body 2 and an attachment portion 3. As shown in FIG. 2, the electric device 1 is used in a state where it is attached to the lighting fixture main body 100.

[0014] The lighting fixture main body 100 is attached to the ceiling of the target space illuminated by the light from the straight tube lamp 200. The lighting fixture main body 100 may be directly attached to the ceiling of the target space (including recessed installation), or may be attached so as to be suspended from the ceiling. By being attached to such a lighting fixture main body 100, the electric device 1 will be installed at a specific position away from the floor of the target space.

[0015] The target space where the lighting fixture main body 100 and the electrical device 1 are installed is, for example, an indoor (interior) space of a non-residential facility such as an office, commercial facility, school, factory, or public facility. However, the target space is not limited to non-residential facilities and may be, for example, a residential facility such as a detached house or an apartment house, or an outdoor facility.

[0016] The device main body 2 is the main body part of the electrical device 1 and has one or more specific functions as the electrical device 1. In this embodiment, as an example, the device main body 2 has an ion generation function of generating ions toward the target space as a specific function.

[0017] The attachment part 3 is a part that can be attached to the lighting fixture main body 100. The attachment part 3 is integrally formed with the device main body 2, and when the attachment part 3 is attached to the lighting fixture main body 100, the device main body 2 is held by the lighting fixture main body 100.

[0018] Here, the attachment part 3 is attached to the lighting fixture main body 100 by using the socket 101 (see FIG. 2) of the lighting fixture main body 100. That is, the attachment part 3 is configured to be attachable to the socket 101 of the lighting fixture main body 100 where a straight tube lamp 200 can be mounted. In other words, the electrical device 1 provided with the attachment part 3 can be attached to the socket 101 of the lighting fixture main body 100 instead of the straight tube lamp 200.

[0019] The lighting fixture main body 100 to which the electrical device 1 is attached is, as shown in FIG. 2, the main body of a lighting fixture to which a straight tube lamp 200 can be mounted. The lighting fixture main body 100 has a socket 101 for mounting the straight tube lamp 200. The socket 101 protrudes downward from the lower surface of the lighting fixture main body 100.

[0020] The straight tube lamp 200 has a pair of caps at both ends in the longitudinal direction (front-rear direction D2), and by being held by a pair of sockets 101, it is spanned between the pair of sockets 101 and attached below the lower surface of the lighting fixture body 100. At least one of the pair of sockets 101 that holds one straight tube lamp 200 includes a power supply terminal for supplying power to the straight tube lamp 200, and power is supplied from the power supply terminal to the straight tube lamp. Therefore, the lighting fixture body 100 can light the straight tube lamp 200 by supplying power from the socket 101 to the straight tube lamp 200.

[0021] By the way, in recent years, lighting devices using LEDs (Light Emitting Diodes) as light sources have been widely distributed for reasons such as excellent power saving and long life. Therefore, even in the lighting fixture body 100, as the straight tube lamp 200, a straight tube LED lamp using an LED as a light source instead of a fluorescent lamp is known. For this type of straight tube lamp 200 using an LED as a light source, for example, in a standard such as "JEL 801" established by the Japan Electric Lamp Industry Association, the shape and the like are defined as a "straight tube LED lamp system with an L-shaped pin cap GX16t-5".

[0022] In this embodiment, as an example, it is assumed that the lighting fixture body 100 and the straight tube lamp 200 comply with the standard of "JEL 801". This straight tube lamp 200 is of a DC (direct current) power supply input type and lights up when a direct current is supplied from the socket 101 of the lighting fixture body 100. That is, the lighting fixture body 100 includes a power supply device that receives power supply from an AC power supply such as a utility power supply and generates a DC power supply, and outputs a direct current from the socket 101.

[0023] Also, in this embodiment, as an example, the lighting fixture main body 100 can be fitted with two straight tube lamps 200. The two straight tube lamps 200 are arranged side by side in a direction (left - right direction D3) orthogonal to the longitudinal direction (front - rear direction D2) of each straight tube lamp 200 in a plan view. That is, the lighting fixture main body 100 has four (two pairs) of sockets 101, and these four sockets 101 are arranged at the four corners of the lighting fixture main body 100 in a plan view.

[0024] In this way, the lighting fixture main body 100 that can be fitted with two straight tube lamps 200 may be used with one of the straight tube lamps 200 removed. That is, the lighting fixture main body 100 that can be fitted with two straight tube lamps 200 may be used with only one straight tube lamp 200 fitted. In this case, among the two pairs (four) of sockets 101, there will be a "void" in the pair of sockets 101 to which the straight tube lamp 200 is not attached. Therefore, in this embodiment, it is assumed that the electrical device 1 is attached to the lighting fixture main body 100 by utilizing such a "void" state socket 101. Therefore, as shown in FIG. 2, both the electrical device 1 and the straight tube lamp 200 are to be attached to the lighting fixture main body 100.

[0025] In particular, when the straight tube lamp 200 is a straight tube LED lamp as described above, due to the improvement in the luminous efficiency of LEDs in recent years and the difference in directivity, etc., the light output per straight tube lamp 200 is larger than that of a fluorescent lamp. Therefore, as a result of the lighting fixture main body 100 being used with one of the straight tube lamps 200 removed (only one fitted), "void" state sockets 101 often occur.

[0026] The electrical device 1 according to this embodiment can be attached to the lighting fixture main body 100 by utilizing such a "void" state socket 101. That is, the electrical device 1 according to this embodiment includes a device main body 2 having a specific function and an attachment portion 3. The attachment portion 3 is configured to be attachable to the socket 101 of the lighting fixture main body 100 to which the straight tube lamp 200 can be attached.

[0027] Therefore, the electrical device 1 can be installed by using the "empty" socket 101 of the lighting fixture main body 100 by the mounting portion 3. Since the lighting fixture main body 100 is generally installed directly on the ceiling of the target space or in a suspended state, the electrical device 1 will also be installed at a specific position away from the floor of the target space.

[0028] As a result, in the electrical device 1 according to the present embodiment, like a stationary electrical device, for example, when the electrical device is installed on the floor of the target space or the like, it can be suppressed that the electrical device obstructs passage or a person touches the electrical device and knocks it over. Therefore, according to the electrical device 1 according to the present embodiment, it is possible to provide an electrical device that is not difficult to install.

[0029] Furthermore, for example, it is also conceivable to add a function equivalent to that of the device main body 2 (for example, a function of generating ions) to the lighting fixture itself to constitute a "lighting fixture with a specific function". However, in this case, in order to use the function, it is necessary to replace the existing lighting fixture with a lighting fixture with a specific function or newly install a lighting fixture with a specific function. The lighting fixture with a specific function is more expensive by the amount of the function as a lighting fixture compared to the electrical device 1 according to the present embodiment. Therefore, according to the electrical device 1 according to the present embodiment, a specific function can be realized at a lower cost compared to a lighting fixture with a specific function.

[0030] [2] Details of the electrical device Next, details including the internal structure of the electrical device 1 according to the present embodiment will be described with reference to FIGS. 3 to 6.

[0031] As shown in FIG. 3, the electrical device 1 includes a housing 10. The housing 10 constitutes the outer shell of the device main body 2. In this embodiment, as an example, the housing 10 has a substantially rectangular parallelepiped shape with a length in the front-rear direction D2. The housing 10 can adopt various shapes, and in addition to a rectangular parallelepiped, for example, it may be a cubic shape, a cylindrical shape, a prismatic shape, etc. The housing 10 is formed of a resin having electrical insulation properties. The housing 10 is in a hollow box shape, and houses a discharge unit 21 (see FIG. 4) etc. inside.

[0032] The attachment portion 3 is configured to protrude forward from the front surface 11 which is one surface of the housing 10. The attachment portion 3 is disposed at the central portion in the left-right direction D3 on the front surface 11 and at a position closer to the upper end portion in the up-down direction D1.

[0033] In this embodiment, the attachment portion 3 has a base (GX-16t-5) shape conforming to the standard of "JEL 801" so as to be attachable to the socket 101 of the lighting fixture main body 100 conforming to the standard of "JEL 801".

[0034] Specifically, the attachment portion 3 includes a pair of terminals 31. Each of the pair of terminals 31 is made of metal and has a pin shape protruding forward from the front surface 11 which is one surface of the housing 10. The pair of terminals 31 are arranged side by side in the left-right direction D3. Each terminal 31 has a shape in which its tip portion (front end portion) is bent outward in the left-right direction D3, and is configured in a substantially L shape as a whole. That is, the tip portion (front end portion) of the right terminal 31 among the pair of terminals 31 extends to the right, and the tip portion (front end portion) of the left terminal 31 extends to the left.

[0035] According to such a pair of terminals 31 having a base shape, when the attachment portion 3 is rotated in a state of being inserted into the socket 101, the pair of terminals 31 are caught inside the socket 101, and the pair of terminals 31 cannot be removed from the socket 101. That is, the attachment portion 3 is mechanically coupled to the socket 101 by the pair of terminals 31 and is held by the socket 101 in a state where the detachment of the socket 101 is restricted.

[0036] Furthermore, the pair of terminals 31 also serves as power supply terminals in the electrical device 1. That is, the pair of terminals 31 has conductivity and is electrically connected to each part of the device body 2 such as the discharge unit 21 inside the housing 10. The pair of terminals 31 is electrically connected to the socket 101, and the device body 2 receives power supply from the socket 101 of the lighting fixture body 100 through the pair of terminals 31.

[0037] In short, in this embodiment, the attachment portion 3 includes the terminals 31 that can be electrically connected to the socket 101. The device body 2 is supplied with power from the socket 101 through the terminals 31. Therefore, the device body 2 will be supplied with power from the lighting fixture body 100. For example, a battery (including a rechargeable battery) or the like for supplying power to the device body 2 becomes unnecessary, and the trouble of battery replacement or charging can be omitted.

[0038] Furthermore, in this embodiment, as described above, the lighting fixture body 100 outputs a direct current from the socket 101, so the electrical device 1 will receive the supply of direct current (direct current power) from the socket 101. That is, the device body 2 is supplied with direct current from the socket 101. Therefore, in the electrical device 1, a power conversion device such as an AC / DC converter for converting alternating current power into direct current power becomes unnecessary, and it is easy to reduce the size and cost of the electrical device 1.

[0039] On the other hand, as shown in FIG. 4, the device body 2 has a discharge unit 21, an air passage 22, and a fan unit 23 inside the housing 10. The device body 2 realizes the ion generation function by these discharge unit 21, air passage 22, and fan unit 23. In FIGS. 4 to 6, the fan unit 23 is shown by an imaginary line (two-dot chain line), and the air flow (air current) is shown by a white arrow.

[0040] As described above, in the electrical device 1 according to this embodiment, the device main body 2 has an ion generation function as a specific function. Since the electrical device 1 is installed near the ceiling of the target space by being attached to the lighting fixture main body 100, the ions generated by the device main body 2 can act efficiently by pouring down into the target space. As a result, it becomes easier to obtain effects such as deodorization and disinfection of the target space by the ions generated by the device main body 2.

[0041] Furthermore, the device main body 2 has intake ports 13 and 14 for taking in air into the housing 10, and an outlet port 15 for blowing out air from the housing 10. Thereby, the device main body 2 can actively blow out the ions generated in the housing 10 by riding on the air flow (air current) taken in from the intake ports 13 and 14 from the outlet port 15.

[0042] Specifically, the intake port 13 is formed on the upper surface of the housing 10, and the intake port 14 is formed on the lower surface 12 (bottom surface) of the housing 10. That is, air is taken in from both sides in the vertical direction D1 of the housing 10. The intake ports 13 and 14 are composed of a plurality of holes penetrating the peripheral wall of the housing 10 in the vertical direction D1. Each of the plurality of holes in the intake ports 13 and 14 is formed in a substantially rectangular shape having a length in the front-rear direction D2, and has an opening area such that foreign matters such as insects do not enter. In this embodiment, the intake ports 13 and 14 are formed on the front side (that is, the front half) of the center of the housing 10 in the front-rear direction D2. Furthermore, intake ports are also formed on both side surfaces of the housing 10 in the left-right direction D3.

[0043] The outlet port 15 is formed on the lower surface 12 (bottom surface) of the housing 10. That is, in a state where the electrical device 1 is attached to the lighting fixture main body 100, the air taken into the housing 10 is blown out from the lower surface 12 facing downward of the housing 10. The outlet port 15 is composed of a plurality of holes penetrating the bottom wall of the housing 10 in the vertical direction D1. Each of the plurality of holes in the outlet port 15 is formed in a substantially rectangular shape having a length in the front-rear direction D2, and has an opening area such that foreign matters such as insects do not enter. In this embodiment, the outlet port 15 is formed at the rear end of the housing 10.

[0044] In this way, the device main body 2 has an ion outlet 15 on the surface (lower surface 12) facing vertically downward in a state where the mounting portion 3 is attached to the socket 101. Therefore, the ions generated in the device main body 2 can act efficiently by pouring down into the target space.

[0045] And inside the housing 10, an air passage 22 for guiding the air taken in from the air inlets 13 and 14 to the outlet 15 is formed. In the present embodiment, corresponding to the pair of upper and lower air inlets 13 and 14, the air passage 22 is configured to merge the air taken in from both of the pair of upper and lower air inlets 13 and 14 and blow it out from the outlet 15 formed on the lower surface 12 of the housing 10.

[0046] The discharge unit 21 has a first discharge electrode 211 and a second discharge electrode 212 (see FIG. 6). The discharge unit 21 has an induction electrode in addition to the first discharge electrode 211 and the second discharge electrode 212. When a voltage (high voltage) is applied between the first discharge electrode 211 and the second discharge electrode 212 and the induction electrode, a discharge occurs between the first discharge electrode 211 and the second discharge electrode 212 and the induction electrode, thereby generating positive ions and negative ions as discharge products.

[0047] The discharge unit 21 is mounted at a position facing the air passage 22 inside the housing 10. The discharge unit 21 is attached to the housing 10 such that at least the first discharge electrode 211 and the second discharge electrode 212 are exposed inside the air passage 22. As a result, the ions (positive ions and negative ions), which are discharge products generated by the discharge unit 21, are discharged out of the housing 10 from the outlet 15 by riding on the air flow passing through the air passage 22.

[0048] Here, as shown in FIGS. 4 and 5, the air passage 22 has a constricted portion 221 with a smaller cross-sectional area than other portions at the site where the first discharge electrode 211 and the second discharge electrode 212 of the discharge unit 21 are arranged. That is, the discharge unit 21 generates ions in the constricted portion 221 of the air passage 22. In particular, in the present embodiment, the constricted portion 221 is formed in the downstream portion near the air outlet 15 of the air passage 22.

[0049] Furthermore, the constricted portion 221 is not horizontally extended, but is inclined downward toward the rear with respect to the horizontal plane so that the position is lower toward the rear end side. Similarly, the discharge unit 21 is also arranged to be inclined downward toward the rear with respect to the horizontal plane. Therefore, the first discharge electrode 211 and the second discharge electrode 212 exposed in the constricted portion 221 are in a posture inclined with respect to the vertical direction (up and down direction D1).

[0050] In this way, the device main body 2 has an air passage 22 through which an air flow for blowing out ions passes. The air passage 22 is inclined with respect to the horizontal plane. Therefore, it is possible to suppress the size of the device main body 2 in plan view (the size in the front-rear direction D2 in the present embodiment) while ensuring a sufficient length of the air passage 22 to make it easy for ions to ride on the air flow. Furthermore, when blowing out ions downward from the air outlet 15, it is possible to blow out the ions while maintaining the momentum of the air flow through the air passage 22. As a result, the ions generated in the device main body 2 can act efficiently by pouring down into the target space.

[0051] Also, the fan unit 23 is arranged on the air passage 22 in the housing 10 and generates an air flow passing through the air passage 22. In the present embodiment, as an example, the fan unit 23 is provided at the end portion (the upstream end portion) opposite to the air outlet 15 in the air passage 22 and generates an air flow (wind) blown out from the air outlet 15 through the air passage 22. Thereby, the air flow generated by the operation of the fan unit 23 blows out from the air outlet 15 located on the lower surface 12 of the housing 10 through the air passage 22.

[0052] Here, the fan unit 23 generates an air current by rotating about a rotation axis Ax1 along the vertical direction D1. However, the rotation axis Ax1 of the fan unit 23 is inclined with respect to the vertical direction (the up-down direction D1).

[0053] That is, in the present embodiment, the device main body 2 has a fan unit 23 that generates an air current. The rotation axis Ax1 of the fan unit 23 is inclined with respect to the horizontal plane. As a result, ions can be blown out while maintaining the momentum of the air current passing through the air passage 22. Consequently, the ions generated by the device main body 2 can act efficiently by pouring down into the target space.

[0054] Further, in the present embodiment, the device main body 2 further has a control unit 24 and a human presence sensor 25 inside the housing 10.

[0055] The discharge unit 21, the fan unit 23, the control unit 24, and the human presence sensor 25 are electrically connected to the terminal 31 of the attachment portion 3, and operate by being supplied with power from the socket 101 through the terminal 31.

[0056] The control unit 24 is electrically connected to the discharge unit 21, the fan unit 23, and the human presence sensor 25. The control unit 24 mainly comprises a computer system having one or more processors such as a CPU (Central Processing Unit) and one or more memories such as a ROM (Read Only Memory) and a RAM (Random Access Memory), and executes various processes (information processing). The control unit 24 controls each part of the device main body 2. Specifically, the control unit 24 controls the discharge unit 21 and the fan unit 23 based on the detection result of the human presence sensor 25, and enables ions to be generated as necessary.

[0057] The human presence sensor 25 is a sensor for detecting the presence of a person. The human presence sensor 25 is, for example, a sensor using a pyroelectric element, and detects the presence or absence of a person within the detection range. The human presence sensor 25 is disposed at the front end of the lower surface 12 of the housing 10. The human presence sensor 25 sets a detection range below the electrical device 1 and detects the presence or absence of a person below the electrical device 1.

[0058] [3] Method for attaching and detaching an electrical device Next, a method for attaching and detaching the electrical device 1 according to the present embodiment will be described with reference to FIG. 7. FIG. 7 shows the procedures for attaching the electrical device 1 to the lighting fixture main body 100 in order from the top.

[0059] That is, first, as shown in the upper part of FIG. 7, the operator moves the electrical device 1 forward in a state where the electrical device 1 faces the "empty" socket 101 in the lighting fixture main body 100 from the rear (thick arrow). At this time, the posture of the electrical device 1 is such that the front surface 11 provided with the attachment portion 3 faces the socket 101, and the lower surface 12 provided with the air outlet 15 faces the left.

[0060] Then, as shown in the middle part of FIG. 7, when the front surface 11 of the electrical device 1 is pressed against the socket 101, the pair of terminals 31 of the attachment portion 3 are inserted into the socket 101. In this state, the operator rotates the device main body 2 of the electrical device 1 about the rotation axis Ax2 (thick arrow). The rotation axis Ax2 is an imaginary axis passing through the center of the attachment portion 3 in a front view and is located at an intermediate position between the pair of terminals 31. At this time, the device main body 2 is rotated counterclockwise by approximately 90 degrees in a front view.

[0061] As a result, as shown in the lower part of FIG. 7, the posture of the electrical device 1 changes to a posture in which the lower surface 12 provided with the air outlet 15 faces downward. In this state, the pair of terminals 31 of the attachment portion 3 are caught by the socket 101, and the attachment portion 3 is attached to the socket 101. Further, in this state, the pair of terminals 31 of the attachment portion 3 are electrically connected to the socket 101, and power supply from the lighting fixture main body 100 to the device main body 2 becomes possible.

[0062] In short, in the electrical device 1 according to this embodiment, the attachment portion 3 is attached to the socket 101 while rotating. As a result, for example, even if a linear external force acts on the device main body 2 backward or downward, the state in which the attachment portion 3 is attached to the socket 101 can be maintained. Therefore, it is possible to prevent the electrical device 1 from being accidentally detached from the socket 101 by the user (or operator).

[0063] By the way, when removing the electrical device 1 from the socket 101, the operator may operate the electrical device 1 in the reverse procedure of the operation shown in FIG. 7 above. That is, the operator can remove the electrical device 1 from the socket 101 by rotating the device main body 2 approximately 90 degrees clockwise in a front view and then moving the device main body 2 backward from the state shown in the lower part of FIG. 7.

[0064] [4] Modification Hereinafter, modifications of Embodiment 1 will be listed. The modifications described below can be applied in appropriate combinations.

[0065] In addition to or instead of the ion generation function, the device main body 2 may have a specific function other than the ion generation function. For example, the device main body 2 may have a detection function for environmental conditions such as the presence or absence of a person, temperature, humidity, or brightness, an air purification function, a blowing function, a heating function, a cooling function, a photographing function, an image projection function, a communication function, a sound output function, or a sound input function.

[0066] Also, it is not essential that the device main body 2 is supplied with power from the socket 101 through the terminal 31. For example, the device main body 2 may be equipped with a battery (including a storage battery) and operate on the power of the battery. In this case, the terminal 31 is simply used to mechanically couple the attachment portion 3 to the socket 101. Furthermore, the terminal 31 may be omitted.

[0067] Also, it is not essential that the lighting fixture main body 100 and the straight tube lamp 200 comply with the standard of "JEL 801".

[0068] In addition, it is not essential for the discharge unit 21 to generate positive and negative ions. For example, discharge products other than ions may be generated by the discharge between the first discharge electrode 211 and the second discharge electrode 212. Also, it is not essential for the discharge unit 21 to have an induction electrode.

[0069] In the discharge unit 21, there is one first discharge electrode 211 and one second discharge electrode 212 each, but there may be a plurality of each. The shapes of the first discharge electrode 211 and the second discharge electrode 212 are not limited to the brush shape, and may be, for example, pin-shaped (needle-shaped), etc.

[0070] Also, the human presence sensor 25 is not an essential component and can be omitted as appropriate. Similarly, the control unit 24 is not an essential component and can be omitted as appropriate.

[0071] In addition, it is not essential for the lighting fixture main body 100 to be able to mount two straight tube lamps 200. The lighting fixture main body 100 may be able to mount only one straight tube lamp 200, or may be able to mount three or more straight tube lamps 200.

[0072] (Embodiment 2) As shown in FIGS. 8 to 10, for the electric device 1A according to this embodiment, the structure of the mounting portion 3 is different from that of Embodiment 1. Hereinafter, for the same configurations as those in Embodiment 1, common reference numerals are given and the description is appropriately omitted.

[0073] In this embodiment, the mounting portion 3 has a holder 32. The holder 32 is formed integrally and continuously with the housing 10 so as to protrude from the front surface 11 of the housing 10. In this embodiment, the holder 32 is disposed below a pair of terminals 31.

[0074] Specifically, the holder 32 includes a beam portion 321 and a claw portion 322. The beam portion 321 has a thickness in the vertical direction D1 and is a plate-like member that protrudes forward from the front surface 11 of the housing 10. The beam portion 321 is flexible in the vertical direction D1 with respect to the housing 10. The claw portion 322 protrudes upward from the tip (front end) of the beam portion 321. The claw portion 322 is formed in a substantially triangular shape whose front surface is inclined obliquely upward in a side view.

[0075] Next, a method for attaching and detaching the electric device 1A according to the present embodiment will be described with reference to FIG. 10. FIG. 10 sequentially shows the procedures for attaching the electric device 1A to the lighting fixture main body 100 from above.

[0076] That is, first, as shown in the upper part of FIG. 10, the operator moves the electric device 1A forward in a state where the electric device 1A faces the "empty" socket 101 in the lighting fixture main body 100 from the rear (thick arrow). At this time, the posture of the electric device 1A is such that the front surface 11 provided with the attachment portion 3 faces the socket 101 and the lower surface 12 provided with the air outlet 15 faces leftward.

[0077] Then, as shown in the middle part of FIG. 10, when the front surface 11 of the electric device 1A is pressed against the socket 101, the pair of terminals 31 of the attachment portion 3 are inserted into the socket 101. At this time, the claw portion 322 of the holder 32 gets over the socket 101, and the holder 32 sandwiches a part (peripheral part) of the socket 101 by sandwiching the socket 101 between the claw portion 322 and the front surface 11 in the front-rear direction D2. In this state, the operator rotates the device main body 2 of the electric device 1A about the rotation axis Ax2 (thick arrow). At this time, the device main body 2 is rotated counterclockwise by approximately 90 degrees in a front view.

[0078] As a result, as shown in the lower part of FIG. 10, while the socket 101 is held by the holder 32, the posture of the electric device 1A changes to a posture in which the lower surface 12 provided with the air outlet 15 faces downward. In this state, the pair of terminals 31 of the mounting portion 3 are caught by the socket 101, and the mounting portion 3 is attached to the socket 101. Moreover, the holder 32 holds a part (peripheral portion) of the socket 101 in a state of sandwiching the socket 101 between the claw portion 322 and the front surface 11 in the front-rear direction D2. Therefore, the electric device 1A is stably attached to the socket 101. Further, in this state, the pair of terminals 31 of the mounting portion 3 are electrically connected to the socket 101, and power can be supplied from the lighting fixture main body 100 to the device main body 2.

[0079] As described above, in the electric device 1A according to the present embodiment, the mounting portion 3 has the holder 32 that holds a part of the socket 101 in a state of being attached to the socket 101. That is, since the claw portion 322 of the holder 32 locks the mounting portion 3 to prevent it from coming off the socket 101, the electric device 1A can be stably attached to the socket 101. For example, when the weight of the electric device 1A is relatively large or the overall length of the electric device 1A (in the front-rear direction D2) is relatively large, there is a possibility of instability in a structure fixed only by the pair of terminals 31 (base), so it is preferable to provide the holder 32.

[0080] By the way, when removing the electric device 1A from the socket 101, the operator may operate the electric device 1A in the reverse procedure of the operation shown in FIG. 10 described above. That is, the operator rotates the device main body 2 approximately 90 degrees clockwise in a front view from the state shown in the lower part of FIG. 10. Further, the operator can remove the electric device 1A from the socket 101 by moving the device main body 2 backward in a state where the holder 32 is bent away from the rotation axis Ax2 to release the lock of the claw portion 322.

[0081] The configuration of the second embodiment can be adopted in appropriate combination with various configurations (including modified examples) described in the first embodiment.

[0082] (Embodiment 3) The electrical device 1B according to this embodiment is different from Embodiment 1 in that the device main body 2 is integrated with the lighting device 4 as shown in FIGS. 11 to 13. Hereinafter, for the same configurations as those in Embodiment 1, common reference numerals are given and the description is appropriately omitted as necessary.

[0083] That is, in this embodiment, the electrical device 1B further includes a lighting device 4 in addition to the device main body 2 and the mounting portion 3. The lighting device 4 has a straight tube shape (cylindrical shape) similar to the straight tube lamp 200 and extends rearward from the rear surface (back surface) of the device main body 2. The lighting device 4 has a base 41 having the same shape as the mounting portion 3 at the end portion (rear end portion) on the side opposite to the device main body 2. That is, the base 41 conforms to the standard of "JEL 801".

[0084] As shown in FIG. 12, the lighting device 4 includes a light source unit 42 including a plurality of LEDs, a heat sink serving as a heat radiating member 43, and a cover 44 covering the light source unit 42. The cover 44 has translucency and transmits the light emitted by the light source unit 42.

[0085] As shown in FIG. 13, this electrical device 1B is attached so as to be bridged between a pair of sockets 101 facing each other in the front-rear direction D2. That is, the electrical device 1B is attached to the pair of sockets 101 in the same manner as the straight tube lamp 200. Here, the mounting portion 3 is attached to one socket 101, and the base 41 of the lighting device 4 is attached to the other socket 101.

[0086] As described above, the electrical device 1B according to this embodiment further includes a lighting device 4 integrated with the device main body 2. According to this configuration, since the target space can be illuminated with the light from the lighting device 4, even when the electrical device 1B is attached instead of the straight tube lamp 200, it is possible to illuminate the target space with sufficient brightness.

[0087] FIG. 14 shows an electrical device 1B according to a modification of Embodiment 3. This electrical device 1B includes device main bodies 2 at both ends in the longitudinal direction (front-rear direction D2) of the lighting device 4. In other words, it is configured to connect the pair of device main bodies 2 with the lighting device 4. According to this configuration, since the electrical device 1B includes a plurality (here, two) of device main bodies 2, it is possible to more effectively exhibit a specific function (here, the ion generation function) of the device main body 2.

[0088] The configuration of Embodiment 3 (including modifications) can be adopted in appropriate combination with various configurations (including modifications) described in Embodiment 1 or Embodiment 2.
