  The case body 4 rotatably holds the base portion 2 via a rotation mechanism, and when a predetermined light bulb Lx is mounted on the socket portion 3, the light source (filament portion) of the light bulb Lx is determined in advance. A socket mounting portion 41 for mounting the socket portion 3 is provided so as to be disposed at the predetermined position.

  Therefore, after first explaining the schematic configuration of the case body 4, the attachment structure of the base part 2 and the socket part 3 will be explained.

  As shown in FIGS. 1 to 6, the case body 4 is formed of a resin molded product formed in a predetermined shape having a substantially cylindrical shape. Specifically, the case body 4 has a base end side opened to form a rotating body fitting portion. And the socket attachment part 41 for mounting | wearing with the base end part 3a of the said socket part 3 on the outer side of this opening part (rotating body fitting part) is projected and formed inward with a predetermined angle (inclination) ( 4 (b)), a concave shape is formed along the outer periphery of the socket portion 3 so that the body of the socket portion 3 does not come into contact with the case body 4 when the socket portion 3 is attached to the socket mounting portion 41. A groove 42 is formed (see FIG. 5).

  When the socket part 3 is attached to the attachment part 41, the base end part 3a of the socket part 3 is screwed onto the rotating shaft of the base part 2 (the base part 2 is screwed to the bulb socket S). In this embodiment, the light source (filament position) of the light bulb Lx attached to the socket portion 3 is positioned substantially on the extension line of the rotation shaft. The case body 4 is provided as described above.

  This is because the adapter device 1 of the present invention is mounted on a light bulb socket S of an existing lighting fixture. Therefore, when the socket portion 3 is arranged coaxially with the rotation axis of the base portion 2, the adapter device 1 This is because the bulb protrudes by the thickness, and thus the projection of the bulb due to the thickness of the adapter device 1 is avoided by tilting the socket portion 3.

(See FIG. 10), the diameter of the socket 3 and the shape and dimensions of the case body 4 are set.

  In the present embodiment, as the light bulb Lx attached to the adapter device 1, a light bulb that is smaller than a general incandescent light bulb (with a base size of E26) (for example, a mini krypton light bulb with a base size of E17) is used. The diameter of the socket 3 and the shape and dimensions of the case body 4 are set according to the size of the light bulb Lx.

  On the other hand, a structure for fitting and holding the electrical board 5 at a predetermined position is provided inside the case body 4. Specifically, in the present embodiment, the electrical board 5 is formed of a substantially D-shaped board as shown in FIG. 6, and therefore the inside of the case body 4 is connected to the D-cut electrical board 5. It has a corresponding shape. That is, the case main body 4 has a structure in which the electric circuit board 5 is fitted and held to accommodate the electric circuit board 5 so as to be rotatable integrally with the case main body 4. 2 is configured such that the positional relationship between the electrical board 5 and the case body 4 does not change even if the position of the board 2 is relatively moved (rotated).

  Here, in this embodiment, when the case main body 4 fits and holds the electrical board 5, the D-cut part (the straight line part on the outer periphery of the board) of the electrical board 5 is placed on the socket mounting part 41 side. Configured to be located.

  Then, in the space inside the case main body 4, the space vacated by the D-cut portion of the electrical circuit board 5, as shown in FIG. 9, is brought into contact with the surface of the rotating body 21 to be described later and supports the rotating portion support 47. And a rotation stopper 48 that engages with a rotation restricting protrusion (not shown) formed on the surface of the rotating body 21 to restrict the rotation of the rotating body 21 and projects toward the rotating body 21. Has been.

  In FIG. 9, reference numerals 33 and 33 denote terminal fittings provided in the socket portion 3. The terminal fittings 33, 33 are passed through terminal insertion holes (not shown) formed in the case body 4 when the socket part 3 is attached to the socket mounting part 41, and the tips thereof are shown in FIG. 9. Placed in position. That is, when the socket part 3 is attached to the socket attachment part 41 in a state where the electrical board 5 is fitted and held at a predetermined position in the case body 4, the terminal fittings 33 and 33 are connected to predetermined parts (sockets of the electrical board 5. The part 3 is in contact with or close to the part 3 electrically connected to the part 3, and the socket part 3 and the electrical board 5 are electrically connected by contacting or soldering them. .

  Further, a metal portion facing the opening of the case main body 4 is located at the inner central portion of the case main body 4 (a concentric position with a rotation shaft (rotation center) when the base portion 2 is screwed into the light bulb socket S). A made nut (nut body) 43 is embedded (see FIG. 4B). As will be described later, the nut 43 has a thread groove that can be engaged with a thread formed at the tip of the conductor pin 24 that is electrically connected to the hot-side electrode of the bulb socket S. When the conductor pin 24 is screwed into the nut 43, the conductor pin 24 is fitted and held at the predetermined position via the nut 43. It is constituted so as to be in contact conduction with the part to be connected).

  Further, the base-side opening end inner peripheral surface of the case body 4 (inner peripheral edge of the rotating body fitting portion) has concave and convex teeth forming a part of a rotating mechanism for rotatably holding the base portion 2. A portion (uneven portion) 44 is formed over the entire circumference. The uneven tooth portion 44 engages with an engaging claw 21c of the rotating body 21 described later to prevent the case main body 4 and the base portion 2 from freely rotating, and the case main body 4 (or the base portion 2). In order to give an appropriate click feeling to the operator during the rotation operation, the present embodiment is configured by providing approximately 40 irregularities on the inner peripheral surface of the opening end of the case body 4. In addition, the position and the number of the unevenness can be appropriately changed as long as the above object is achieved. That is, in the present embodiment, the uneven tooth portion 44 is formed on the entire circumference of the inner peripheral surface of the opening end, but it may be provided only on a part of the inner peripheral surface, and the number thereof can be appropriately increased or decreased. is there.

  Further, as shown in FIG. 4, a through hole (opening) 45 penetrating into the case body 4 is formed on the outer surface of the case body 4. This through hole 45 is not only the heat accumulated in the case body 4 (that is, not only the heat generated from the electrical components mounted on the electrical board 5 but also the heat of the bulb received from the surface of the socket part 3 and the case body 4). Are provided for discharging heat to the outside of the case body 4 and are provided in appropriate numbers at appropriate positions on the outer periphery of the case body. In addition, a part of the through hole also acts as a signal intake port for a signal receiving unit (receiving unit) 51 described later to receive an infrared signal.

  In the present embodiment, as will be described later, the electrical component board 5 is provided with electrical components having a large amount of heat generation at a position near the base end portion 3a of the socket portion 3, and the base portion of the socket portion 3 is used in use. Since the position of the case body 4 is adjusted so that the end portion 3a side is positioned upward, the through hole 45 is positioned close to the base end portion 3a of the socket portion 3 of the case body 4 and its opposite position (FIG. 4 ( Since the air in the case body 4 convects through the through-holes 45, the heat in the case body 4 can be efficiently discharged.

  Further, as shown in FIG. 4, the outer peripheral edge 46 on the front side of the case body 4 is subjected to a taper-shaped corner dropping process (so-called C cut). This is because when the light bulb Lx is mounted on the socket portion 3, the outer peripheral edge of the front of the case body facing the light bulb Lx is cut off, so that when the light bulb Lx is turned on, the light is emitted from the light bulb Lx. This is to reduce the area of the case body 4 that receives light and heat (see FIG. 10).

  Next, the base part 2 will be described. The base part 2 includes a base having a shape that can be engaged with the socket S for a light bulb. That is, in this embodiment, since the socket corresponding to the incandescent light bulb L whose base size is “E26” is adopted as the above-mentioned light bulb socket S, the base portion 2 has the same size as the light bulb of “E26”. Constructed with a base.

  And in the adapter apparatus 1 which concerns on this invention, this nozzle | cap | die part 2 is rotatably hold | maintained at the said case main body 4 via the rotation mechanism. Specifically, as shown in FIG. 6, the base part 2 includes a rotating body 21, a base body (cold side metal fitting) 22, an insulating shaft body 23, a conductor pin (hot side metal fitting) 24, Is configured as a main part, and is rotatably attached to the case body 4 with the conductor pin 24 as a rotation axis.

  The rotating body 21 is a member for rotatably holding the base portion 2 (in other words, the base body 22) to the case body 4 independently of the conductor pins 24, and is a substantially disk-shaped rotation. The body main body portion 21a is formed of an integrally molded resin product in which a hollow cylindrical boss portion 21b protrudes from the center of the back surface. The boss portion 21b is a projection for fitting the base body 22, and an opening for mounting the sheath tube portion 23a of the insulating shaft body 23 is formed on the top surface of the boss portion 21b (FIG. 4). (See (b)).

  An engaging claw (claw portion) 21c that elastically engages with the concave portion of the concave and convex tooth portion 44 formed on the inner peripheral edge of the opening of the case main body 4 is formed at a predetermined position on the outer peripheral edge of the rotating body main body portion 21a. ing. The engaging claw 21c constitutes a part of the rotating mechanism together with the concave and convex tooth portion 44 of the case body 4, and prevents the rotating body 21 held by the case body 4 from freely rotating and rotating operation. It is provided to give the operator an appropriate click feeling when performing the operation. However, the engagement strength (click feeling) between the engagement claw 21c and the concave and convex tooth portion 44 is not limited even when the case body 4 is rotated counterclockwise when the position of the light bulb Lx is adjusted, which will be described later. In order not to loosen the attachment of the base part 2 to the socket S for use, it is set not to be too strong. Therefore, in the present embodiment, the engaging claw 21c having a thickness of about 2 to 3 mm formed integrally with the rotating body main body 21 with a plastic resin is used.

  The engaging claws 21c may be provided at least at one place on the outer peripheral edge of the rotating body main body 21a. However, as shown in FIG. It is also possible to provide a plurality of pairs such as a pair provided at symmetrical positions across the conductor pin 24).

  Further, at a predetermined position on the surface of the rotating body main body portion 21a (specifically, a position concentric with the rotation stopper 48 provided on the main body case 4 side), a rotation restricting protrusion for restricting the rotation of the base portion 2 is provided. (Not shown) is formed so that the rotation restricting projection collides with the rotation stopper 48 when the rotating body 21 is rotated, whereby the rotation of the base portion 2 (or the body case 4) is performed as shown in FIG. ) Is limited to a range indicated by an arrow (a range between symbols XY in the drawing). That is, in the present embodiment, the base portion 2 is set to be able to rotate approximately 360 ° (specifically, less than 360 °) to the left and right while being held by the case body 4.

  In this way, the rotation range of the base portion 2 is limited by the rotation stopper 48, as will be described later, the force (rotation direction) applied to the case body 4 when the adapter device 1 is attached to the bulb socket S. This is because the rotation range is set to approximately 360 °, as will be described later, in the boss 21b of the rotating body 21, the base body Since the electric wire 6 for connecting the electric wire 22 and the electric board 5 is arranged, the stress of the electric wire 6 due to the rotation of the base part 2 (or the case body 4) (stripping the soldering of the electric wire) ) Is not applied. Accordingly, the design of the rotatable range can be changed as appropriate according to the length of the electrical wire 6 and the like.

  The base body 22 is a member that is electrically connected to the cold-side electrode of the bulb socket S, and is formed of a hollow (cylindrical) metal (conductor) member. The outer peripheral surface of the body portion 22a is formed with a screw thread that is screwed into the receptacle of the bulb socket S, and its base end portion is an inwardly extending portion (flange) toward the inner peripheral side. Part) 22b is formed, and a solder mounting allowance (not shown) for soldering one end of the electrical wire 6 is provided on the overhanging part 22b.

  As shown in FIG. 6, the base body 22 has an opening at the tip thereof fitted into the boss part 21 b of the rotating body 21, and a substantially entire region of the protruding part 22 b of the base body 22 on the outer side. A substantially U-shaped reinforcing metal fitting 25 that covers the outer surface of the rotating body 21 is fixed to the boss portion 21b of the rotating body 21 with screws 26 and 26 in this state. Is attached to the rotating body 21.

  The insulating shaft body 23 is a member that is entirely composed of an insulator and electrically insulates the conductor pin 24 penetrating the base portion 2 and the base body 22 from each other. A cylindrical sheath tube portion 23a through which the portion 24b is inserted, and a circumferential direction (outside) so as to cover the base end portion (reinforcing metal fitting 25 and screw 26) of the base body 22 on the base end side of the sheath tube portion 23a ) And a flange portion 23b formed in a protruding manner.

  As described above, the sheath tube portion 23a of the insulating shaft body 23 has an outer diameter that can be inserted into the opening provided on the top surface of the boss portion 21b of the rotating body 21, and the shaft of the sheath tube portion 23a. As shown in FIG. 4B, the direction length is set to a length that reaches the back surface of the electrical board 5 when the base part 2 is assembled. Here, the reason why the axial length of the sheath tube portion 23 a is set so as to reach the back surface of the electrical board 5 is that the insulating shaft body 23 has a structure covering the entire circumference of the conductor pin 24. By setting the length so as to reach the back surface of the electrical board 5, even if the electrical wire 6 soldered to the back surface of the electrical board 5 is disconnected for some reason, the tip of the electrical wire 6 is connected to the conductor pin 24. This is so as not to touch the surface.

  The conductor pin 24 is a member that is electrically connected to the hot-side electrode of the bulb socket S so that the pin head portion 24a corresponds to a solder portion formed at the tip of the cap of the incandescent bulb L. The pin shaft portion 24b has a predetermined length so that it can be screwed with a nut 43 attached to the case body 4 to be described later, while having a shape protruding from the surface of the flange portion 23b of the insulating shaft body 23. And has a thread formed at the tip.

  Thus, as shown in FIG. 6, the base part 2 composed of such a member first fits the electrical substrate 5 inside the case body 4, and then the base body 22 and the reinforcing bracket 25. Is inserted through the sheath tube portion 23a of the insulating shaft body 23, and the pin shaft portion 24b of the conductor pin 24 is inserted through the sheath tube portion 23a. The tip of 24 b is assembled to the case body 4 by screwing into the nut 43. That is, the base part 2 is assembled so that the electrical board 5, the rotating body 21, and the insulating shaft body 23 are sandwiched between the conductor pin 24 and the nut 43 (case body 4). Thus, in the present embodiment, the base body 22 (cold side metal fitting) of the base part 2 is configured to be rotatable independently of the case main body 4 and the conductor pin (hot side metal fitting) 24.

  At that time, the electric wire 6 is soldered to the solder mounting allowance of the base body 22 and a predetermined portion of the electric substrate 5, and thereby both are electrically connected. The electrical wire 6 has an appropriate length so that the length thereof is not insufficient even when the base portion 2 rotates within the above-described range, and the boss is wound around the sheath tube portion 23a of the insulating shaft body 23. It is stored in the part 21b. That is, even when the electric wire 6 rotates the cap part 2 to the position where the rotation is restricted to the maximum, as shown in FIG. 4 (b), the outer periphery of the sheath pipe part 23a of the insulating shaft body 23 It winds around and is wound around the sheath tube portion 23a so that the soldered portion is not peeled off.

  On the other hand, as described above, the socket portion 3 is a socket for mounting a mini-krypton bulb (bulb Lx) having a 17E base, and the bulb is screwed into a substantially cylindrical socket case 31 made of resin. A metal receiver 32 having a thread groove for mating is provided. The receiving metal 32 is connected to the terminal fittings 33 and 33 described above, and the terminal fittings 33 and 33 are provided so as to protrude outward from the base end portion of the socket case 31 (see FIG. 5). ).

  The socket portion 3 abuts the base end surface thereof on the socket mounting portion 41 of the case body 4 (in this case, the terminal fittings 33 and 33 are inserted into terminal insertion holes (not shown) of the case body 4). In this state, the socket mounting portion 41 is mounted and fixed to the socket mounting portion 41 by the mounting screw 34 from the back side.

  And in this embodiment, as shown in FIG. 5, the reflecting plate 7 and the heat insulating material 8 are further attached to the front surface of the case body 4 to which the base portion 2 and the socket portion 3 are thus attached. Yes.

  Specifically, the reflection plate 7 is disposed so as to reflect light and heat emitted from the light bulb Lx at a portion facing the light bulb Lx when the light bulb Lx is attached to the socket portion 3. In this embodiment, a metal plate made of aluminum or stainless steel that is bent into a predetermined shape according to the shape of the front surface of the case body 4 is used.

  The heat insulating material 8 is interposed between the case body 4 and the reflection plate 7 so that the heat of the reflection plate 7 heated and heated by heat radiated from the light bulb Lx or the like is not transmitted to the case body 4. A heat insulating material layer that is processed into a predetermined shape in accordance with the shape of the front surface of the case main body 4 is used in the same manner as the reflector 7.

  And the attachment to these case main bodies 4 piles the heat insulating material 8 and the reflecting plate 7 on the front of the case main body 4, and fixes with screws 9 from the front side in that state. In this case, the reflector 7 and the body of the socket portion 3 are not in contact with each other as in the case of the case body 4. That is, when the case body 4 is molded, the thickness of the heat insulating material 8 and the reflection plate 7 is taken into consideration so that they are not in contact with the body of the socket portion 3.

  Thus, the adapter device 1 configured as described above is used with the cap portion 2 attached to the light bulb socket S so that the light bulb Lx faces substantially obliquely downward as shown in FIG. .

  That is, in use, first, the glove G of the lighting fixture is removed, and in this state, the base portion 2 of the adapter device 1 in which the light bulb Lx is attached to the socket portion 3 is attached to the socket S for the light bulb. When attaching the base part 2, the case body 4 is held in hand and the base part 2 is attached by screwing the base part 2 into the socket of the bulb socket S in the clockwise direction. At this time, the base portion 2 is rotatably held by the case main body 4, but the base portion 2 is elastically engaged with the concave and convex tooth portions 44 of the case main body 4 by the engaging claws 21c. When the screw is screwed in, the base part 2 rotates integrally with the case body 4 and is attached to the socket of the bulb socket S.

  Then, when the cap 2 is screwed into the light bulb socket S (in other words, when the pin head 24a of the conductor pin 24 is screwed into contact with the terminal at the back of the light bulb socket S), there. Although the base part 2 stops rotating, the base part 2 is rotatably held by the case body 4, so that the case body 4 can be rotated at this point.

  When the case body 4 is further rotated in a state in which the rotation of the base portion 2 is stopped, the engaging claw 21c is repelled and the engaging claw 21c is elastically engaged with the adjacent concave portion. A click feeling such as “click” is transmitted to the operator along with the sound. This rotation operation is possible until the rotation stopper 48 provided on the case body 4 and the rotation restricting projection of the base portion 2 collide with each other, and when the two collide, the case body 4 does not rotate any further. In this way, by rotating the case body 4 until the case body 4 stops rotating, the electrical connection between the pin head 24a of the conductor pin 24 and the terminal at the back of the bulb socket S is performed. Can be ensured.

  In this state, when the case body 4 is further rotated, the base body 22 tries to enter the socket of the bulb socket S, but the base part 2 cannot be screwed any further. As a result, the base part 2 The base body 22 is subjected to a force for peeling the base body 22 from the rotating body 21. However, in the present embodiment, as described above, the base end portion of the base body 22 is screwed and fixed to the boss portion 21b of the rotating body 21 via the reinforcing metal fitting 25, so that Even if a force is applied, the base body 22 does not float from the rotating body 21, and it is possible to prevent the base part 2 from malfunctioning.

  In this way, when the cap part 2 is attached to the socket S for the light bulb, the attachment of the adapter device 1 is completed if the light bulb Lx is obliquely downward as shown in FIG. The case body 4 is rotated in the opposite direction (counterclockwise), and the position of the light bulb Lx is adjusted so as to be obliquely downward. At that time, if the base part 2 is firmly attached to the socket S for the light bulb, the base part 2 does not rotate and only the case body 4 rotates, so that the orientation of the light bulb Lx does not loosen the attachment of the base part 2. Can be adjusted. In addition, when the concave and convex tooth portion 44 and the engaging claw 21c are engaged at the adjusted position, the relative positions of the case body 4 and the base portion 2 are positioned, and the positions of both may be arbitrarily shifted. Absent.

  Then, when the position adjustment of the light bulb Lx is completed, finally, the globe G is attached to the lighting fixture, and the attachment of the adapter device 1 is completed.

  As described above, the adapter device 1 is adjusted and used so that the direction of the light bulb Lx is obliquely downward. The heat generated by the filament of the light bulb Lx when the light bulb is lit is propagated upward along the socket portion 3. Accordingly, the heat concentrated on the glass bulb portion of the bulb is dispersed, thereby preventing the heat from being concentrated on a specific portion of the globe G (the upper portion of the bulb of the bulb) and the heat transmitted to the socket portion 3. This is to suppress the transmission to the electrical board 5 in the case body 4.

  Next, the electrical configuration of the adapter device 1 will be described with reference to FIG. As shown in FIG. 7, in the adapter device 1, the base portion 2 and the socket portion 3 are electrically connected via an electrical board 5.

  The electrical board 5 is mounted with electrical components for receiving dimming control information from the outside and performing dimming control of the light bulb Lx attached to the socket portion 3 based on the control information. As shown in the figure, a signal receiving unit 51, a power control unit 52, a temperature detection unit 53, a control unit 54, and a power supply unit 55 are provided as main units.

  The signal receiving unit (receiving unit) 51 is a receiving device that receives control information transmitted from the remote controller 10, and in the present embodiment, the signal receiving unit 51 is configured by an infrared light receiving device. That is, in the present embodiment, as shown in FIG. 7, the remote controller 10 that transmits control information is generated by the remote controller control unit 12 in response to an operation on the operation unit 11, and the control information is transmitted to the signal transmission unit. The signal receiving unit 51 is configured as an infrared light receiving device capable of receiving the infrared signal because it is converted into an infrared signal at 13 and transmitted and emitted. Therefore, the signal receiving unit 51 can be appropriately changed according to the signal transmission form of the remote controller 10.

  The signal receiving unit 51 has an infrared light receiving unit mounted on the surface of the electrical board 5 and receives control information (infrared signal) from the outside through the through hole 45 provided on the outer periphery of the case body 4 described above. Is configured to do. Specifically, when the case body 4 is adjusted to an appropriate position, it is arranged at a position where the signal reception state is best.

  The power control unit 52 is a circuit that adjusts the brightness of the light bulb Lx attached to the socket unit 3 (performs dimming control) on the basis of the dimming control signal given from the control unit 54. Specifically, it is composed of a phase control circuit that performs phase control of electric power supplied from the base 2 and applied to the socket 3 based on the dimming control signal. Since the configuration of this phase control circuit is well known, detailed description is omitted.

  The temperature detection unit 53 is configured so that when the electrical circuit board 5 is fitted and held at a predetermined position in the case body 4 and the position of the case body 4 is adjusted so that the light bulb Lx is inclined downward, the electrical circuit board 5 It is composed of a pair of thermistors (temperature detection means) Th1 and Th2 arranged vertically (in other words, a position close to the base end portion 3a and a position far from the base end portion 3a).

  Specifically, as described above, in the present embodiment, a D-cut board is used as the electrical board 5, and the cut part (the straight part on the outer periphery of the board) is the base end of the socket part 3. Since the thermistors Th1 and Th2 are disposed at positions close to the portion 3a, the thermistors Th1 and Th2 are disposed at two locations on the electrical board 5 as shown in FIG.

  In this connection, in the present embodiment, among the electrical components that constitute the power control unit 52 and the power supply unit 55, the electrical components having a large amount of heat generation such as a triac and a resistor are located above the electrical substrate 5, That is, the electrical component board 5 is mounted on the electrical component substrate 5 so as to be disposed at a position close to the base end portion 3 a of the socket portion 3 when the electrical component substrate 5 is accommodated and held in the case body 4. Along with this, the heat-sensitive electrical components such as the microcomputer of the control unit 54 and the infrared light receiving unit are disposed below the electrical board 5.

  This is because by disposing an electrical component having a large amount of heat generation upward, a component that is vulnerable to heat due to heat generated from the electrical component is prevented from causing a malfunction. Therefore, in the present embodiment, when the case body 4 is correctly adjusted (when the light bulb Lx is adjusted to be obliquely downward), the temperature of the upper part of the electrical board 5 is high and the temperature of the lower part is high. Becomes lower.

  The temperature detection unit 53 is for detecting such a temperature difference in the electrical board 5, and temperature information detected by the temperature detection unit 53 is input to the control unit 54.

  The control unit 54 constitutes a control center of the adapter device 1 and includes a microcomputer that stores a predetermined control program. Specifically, the control unit 54 controls the power control unit 52 based on the control information given from the signal receiving unit 51 (dimming control process) and the temperature information from the temperature detection unit 53. And a process (position detection process) for determining whether or not the electrical board 5 (in other words, the light bulb Lx) is at the correct position. The control unit 54 and the power control unit 52 constitute a dimming control unit that performs dimming control of the light bulb Lx.

  Therefore, first, the dimming control process in the control unit 54 will be described. In order to execute the dimming control process, the control unit 54 includes a program (signal analysis program) for analyzing the control information received by the signal receiving unit 51 and dimming control according to the analysis result of the control information. A program for generating a signal (a dimming control signal generation program) is stored.

  For example, when the control information received by the signal receiving unit 51 is a “command to darken illumination”, the control unit 54 controls the dimming control signal corresponding to this command, that is, the power control unit 52. Is given a command to reduce the power supplied to the socket section 3 so that the light of the light bulb Lx becomes dark. On the other hand, when the received control information is a “command to brighten the illumination”, the control unit 54 increases the power supplied to the socket unit 3 to the power control unit 52 in response to this command. A command is given to order to do so that the light of the light bulb Lx becomes brighter.

  The specific contents of the dimming control process are appropriately designed by changing the settings of the remote control unit 12 of the remote controller 10 and the contents of the signal analysis program and dimming control signal generation program in the control unit 54. It can be changed. For example, in the above-described example, the control information generated by the remote controller control unit 12 includes the information on whether to make the illumination darker or brighter. When the control information is received from the camera, the power is reduced by a predetermined amount according to the control information, and the illumination is dimmed. When the control information is received a predetermined number of times, the illumination is returned to the original state. It can also be set. In short, the control unit 54 and the power control unit 52 may be configured to perform dimming control of the light bulb Lx based on dimming control information given to the signal receiving unit 51 from the outside.

  Next, the position detection process in the control unit 54 will be described. As described above, the adapter device 1 according to the present invention adjusts the position of the case main body 4 so that the light bulb Lx faces obliquely downward when the cap portion 2 is attached to the light bulb socket S. If the position of the case body 4 is not in an appropriate position, the above-described effects of heat dissipation and exhaust heat cannot function sufficiently, and the above-described infrared signal reception state is deteriorated. Therefore, in the adapter device 1 of the present invention, the control unit 54 determines whether or not the case body 4 (in other words, the electrical board 5) is in an appropriate position based on the temperature information from the temperature detection unit 53. It is configured as follows.

  Specifically, the control unit 54 reads the data (temperature information) obtained by the thermistors Th1 and Th2, and determines whether or not the case body 4 is in an appropriate position based on the temperature difference between the two. . Here, the detection value (detection temperature) of the thermistor Th1 attached above the electrical board 5 is T1, and the detection value (detection temperature) of the thermistor Th2 attached below the electrical board 5 is T2.

  When the light bulb Lx is turned on at an appropriate position of the case body 4, the electrical components having a large amount of heat generation are arranged above the electrical board 5 in the present embodiment. Therefore, the detected values of the thermistors Th1 and Th2 are as shown in FIG. As shown in FIG. 12 (a), the temperature rises with time, and the temperature difference (T1-T2) between the two increases.

  On the other hand, for example, when the case main body 4 is deviated by nearly 90 ° from the proper position, as shown in FIG. Although T2 rises, the temperature difference between them (T1-T2) is smaller than when the case body 4 is in the proper position. Further, if the position of the case body 4 is shifted by nearly 180 °, the temperature difference further approaches 0, and in some cases, the temperature difference may become negative.

  In the present embodiment, the control unit 54 determines whether or not the position of the case body 4 is appropriate by paying attention to the appearance of the temperature difference between the detection values T1 and T2 of the thermistors Th1 and Th2 depending on the position of the case body 4. When the light bulb Lx is turned on, the control unit 54 starts reading the detection values T1 and T2 of the thermistors Th1 and Th2, and the temperatures T1 and T2 of the both are determined to be a predetermined temperature. When Ta is reached, it is determined whether “T1> T2 and the temperature difference (T1−T2) is equal to or greater than a predetermined value Tb”. If the result is positive, “the case body 4 is in an appropriate position”. If the result is negative, it is determined that “the case body 4 is not in an appropriate position”.

  As a result of this determination, when it is determined that “the case body 4 is not in the proper position”, the control unit 54 is configured to execute a predetermined warning process for notifying the user of that fact. As this warning processing, for example, the light bulb Lx is blinked at a predetermined cycle (for example, 500 ms), or is forcibly dimmed to a predetermined level (brightness). Done.

  As described above, in the adapter device 1 according to the present embodiment, when the case body 4 is not in an appropriate position, the control unit 54 detects this and executes a warning process. Inadequate adjustment) can be detected at an early stage, and abnormal temperature rise of the electrical components in the adapter device 1 can be prevented in advance. In addition, since the case body 4 can be kept at an appropriate position, the receiving means can be arranged at a position suitable for reception, and normal reception can be performed.

  The power supply unit 55 includes a power supply circuit that generates a DC voltage from the AC power supplied to the base unit 2 and supplies the DC power to each unit of the electrical board 5.

Embodiment 2
Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the mounting direction of the light bulb Lx is modified. Specifically, as shown in the drawing, the socket portion 3 'is integrally formed with the case body 4'. Although there are structural differences from the first embodiment, the structure of the base part 2 including the rotation mechanism and the assembling method thereof, in other words, the structure in which the base part 2 is rotatably held by the case body 4, and the electrical board Since the other basic configurations such as the holding structure 5 and its electrical configuration are the same as those in the first embodiment, the same reference numerals are given to the portions having the same configurations, and the description thereof is omitted.

  That is, as shown in FIGS. 15 and 16, the case body 4 'in the present embodiment has a socket portion 3' formed integrally with the case body 4 'at the center of the surface of the case body 4'. Specifically, a part of the body portion of the substantially cylindrical socket case 31 'is provided so as to protrude from the surface of the case body 4', and many other portions are provided so as to protrude into the case body 4 '. ing.

  In the socket case 31 ′, a hot-side and cold-side metal receiver 32 ′ is provided as in the above-described embodiment. Specifically, as shown in FIGS. 14 (a) and 15 (b), the hot-side receiver 32a is provided so that one piece rises toward the surface side at the center of the inner bottom surface of the socket case 31 '. It consists of a piece of metal. Further, the cold-side metal receiver 32b is formed of a substantially cylindrical metal member having a thread groove for mounting the light bulb Lx on the inner peripheral surface.

  Then, the assembling of each of the receivers 32a and 32b to the socket case 31 'is screwed (or caulked) by metal screws (or pins) 35 and 36 penetrating the bottom surface of the socket case 31'. And is attached to the socket case 31 'so that the two receiving plates 32a and 32b do not come into contact with each other.

  It should be noted that the electrical connection between each of the receivers 32a and 32b and the electrical board 5 is a connection that is electrically connected to the receivers 32a and 32b when the screws 35 and 36 are attached to the receivers 32a and 32b. The metal fitting 37 is mounted on the socket case 31 'side, and one end of the connecting metal fitting 37 is soldered to the electrical board 5 or the like (see FIG. 15B).

  In this embodiment, since the socket case 31 'is provided at the center of the case body 4', the nut 43 for screwing the conductor pin 24 is provided at the base end of the socket case 31 '. Buried.

  In addition to the case main body 4 ', the socket portion 3' is provided at the center of the surface of the case main body 4 'as described above, and as shown in FIG. 16, the reflection plate 7' and the heat insulating material 8 ' The specific shape is also changed. That is, the reflection plate 7 'and the heat insulating material 8' are formed with a through-hole for inserting the socket portion 3 'in the center thereof.

  In addition, other configurations, for example, a point where a plurality of through holes (openings) 45 are provided on the outer periphery of the case main body 4 ′, and the front side outer peripheral edge 46 of the case main body 4 ′ are tapered to form a corner (so-called C-cut). ) Is the same as in the above-described embodiment.

  Thus, the adapter device 1 'constructed in this way has the socket portion 3' provided perpendicularly to the center of the surface of the case body 4 '. Then, the light bulb Lx attached to the socket portion 3 ′ is arranged so as to be orthogonal to the wall surface W.

  In the above-described first embodiment, when the adapter device 1 is used, it is assumed that the position of the case body 4 is adjusted so that the light bulb Lx is inclined downward (the adapter device 1 is in an appropriate position). Positions of electrical components and temperature detection means on the substrate 5 are set (that is, electrical components with a large amount of heat generation are arranged above the electrical component board 5 when the adapter device 1 is used, and temperature detection means are arranged at two locations above and below. However, in this embodiment, since the light bulb Lx is attached to the center of the case body 4 'so as to be orthogonal to the wall surface W, the appearance of the adapter device 1' (for example, the light bulb Lx and the socket) It is difficult to determine an appropriate position of the adapter device 1 ′ only by visually observing the direction of the portion 3 ′.

  Therefore, in the adapter device 1 shown in the present embodiment, on the surface of the adapter device 1 ′ (for example, the outer peripheral surface of the case body 4 ′) so that the proper position of the case body 4 ′ can be determined by visually observing the appearance. Display means (not shown) for displaying an appropriate position is provided.

  That is, also in this embodiment, the electrical component on the electrical board 5 and the temperature detection means are such that when the adapter device 1 ′ is mounted at an appropriate position, the electrical component with a large amount of heat is located above the board 5, In addition, the temperature detecting means is disposed so as to be located at two positions above and below the substrate 5, and if the adapter device 1 'is not in an appropriate position, the control unit 54 detects this and performs a predetermined warning process (for example, a light bulb). For example, a process of causing Lx to blink at a predetermined cycle).

  Thus, the adapter device according to the present invention can also change the mounting direction of the light bulb Lx. That is, in this case, since the socket portion 3 'is in the case main body 4', the heat dissipation effect in the socket portion 3 'cannot be expected, but the heat conductivity to the socket portion 3' is low. It should be noted that other heat exhaust effects (for example, heat exhaust by the through hole 45 of the case body 4 ', promotion of exhaust heat by positioning an electrical component with a large amount of heat upward), the reflector 7' and heat insulation, etc. The effect of suppressing the temperature rise in the case body 4 by the material 8 'is the same as that of the first embodiment.

  In addition, embodiment mentioned above shows the preferred embodiment of this invention, Comprising: This invention is not limited to these, A various design change is possible within the range.

  For example, in the above-described embodiment, the case where a mini-krypton light bulb is used as the light bulb Lx attached to the adapter device has been described. However, an incandescent light bulb or a light bulb type fluorescent lamp can be used as long as the light can be dimmed by power control. It is also possible to use other bulbs / fluorescent lamps.

  In the above-described embodiment, the light bulb Lx is smaller than the incandescent light bulb L attached to the light bulb socket S. However, the dimming adapter device 1 is interposed between the light bulb and the light bulb socket. If it is possible to attach the glove G in a worn state, it is possible to use a normal light bulb with the socket diameter of the socket portion 3 being a normal light bulb size. In the embodiment described above, a base having the same structure as the E26 type is used as the base part 2, but this size can be changed as appropriate, for example, E17.

  Moreover, although the case where alternating current power was supplied to the said nozzle | cap | die part 2 was shown in embodiment mentioned above, this invention is applicable also when direct current power is supplied. That is, in this case, the power control unit 52 is configured by a dimming circuit that performs dimming of the light bulb Lx based on DC power.

  In the above-described embodiment, the detection values T1 and T2 of the thermistors Th1 and Th2 provided on the electrical board 5 are used only for determining whether or not the positions of the case bodies 4 and 4 ′ are appropriate. However, it is also possible to configure the control unit 54 to detect an abnormal temperature rise in the case main bodies 4 and 4 ′ based on these detection values T1 and T2 and to perform a predetermined warning process.

  Further, two or more of the thermistors Th1 and Th2 are arranged, and based on these, the temperature distribution and temperature difference in the case main bodies 4 and 4 ′, and the temperature rising pattern are monitored by the control unit 54, and the rated power is determined. It is also possible to monitor the installation of a light bulb that exceeds the light bulb or a light bulb that generates a large amount of heat.

  Further, in the above-described embodiment, with respect to the rotation mechanism that holds the base portion 2 on the case main bodies 4 and 4 ′ in a rotatable manner, the concave and convex tooth portions 44 are engaged with and engaged with the case main bodies 4 and 4 ′. Although the configuration in which the joint claw 21c is provided on the rotating body 21 side is shown, it is also possible to provide the concave and convex tooth portion on the rotating body 21 and the engaging claw on the case main body 4.

  In the above-described embodiment, the case where the conductor pins 24 are attached to the case bodies 4 and 4 ′ by screwing the conductor pins 24 into the nuts 43 embedded in the case bodies 4 and 4 ′ is shown. However, for example, the electrical board 5 is fixed in the case body 4, 4 ′ so as to rotate integrally with the case body 4, 4 ′, and the nut 43 is attached to the electrical board 5. It is also possible. That is, the nut 43 is provided with a pin (not shown) for mounting on the electrical board 5, and this pin is fixed to the electrical board 5 by soldering or the like. Thus, in the configuration in which the nut 43 is provided on the electrical board 5 in this way, the rotating body 21 is rotatably held between the nut 43 and the pin head 24 a of the conductor pin 24.

  In the second embodiment described above, the socket portion 3 'is provided integrally with the case main body 4'. However, the socket portion 3 'may be configured independently of the case main body 4'. That is, in this case, for example, a concave portion corresponding to the socket portion 3 'can be formed in the center of the case body 4', and the socket portion 3 'can be attached to the concave portion.

  As an application of the present invention, when a control board for dimming control is built in the pedestal B of the lighting fixture, the reflector B and the heat insulating material as described above are disposed on the pedestal B. Alternatively, the outer peripheral portion of the surface of the pedestal B can be cut off with a corner.
