  In the insulating case 16 configured as described above, the lighting device 17 is housed, and the insulating case 16 housing the lighting device is housed and supported in the main body 13. At the same time, the insulating case 16 is protruded from the other end portion side of the main body 13 by inserting the base support portion 16c integrally formed on the other end side through the opening 13b on the other end side of the main body 13 The resin ring 15 is attached to the base support portion 16c, and the base member 14 is further attached.

  First, the lighting device will be described. As shown in FIG. 2, the lighting device 17 includes a circuit component 17a constituting a lighting circuit for each LED 11, and a circuit board 17b on which the circuit components are mounted. The lighting circuit is configured to convert the AC voltage 100V into a DC voltage of about 24V and supply a constant DC current to each LED 11. The circuit board 17b is made of a glass epoxy material having a strip shape, and a circuit component 17a made of an electronic component is mounted on one side or both sides of the circuit board 17b. The pair of support grooves formed on the inner surface of the insulating case 16 with the circuit board 17b in the vertical direction. By inserting and fitting in 16d, the lighting device 17 is accommodated in the vertical direction inside the insulating case 16 and supported. The pair of support grooves 16d of the insulating case 16 are formed so as to be offset from one side of the main body axis xx to accommodate the circuit component 17a of the circuit board 17b in order to form a wide space on one side. Moreover, the electric wire c is connected to the output terminal of the circuit board 17b, and the input line (not shown) connected to the cap member 14 is connected to the input terminal.

  With the above, the insulating case 16 that houses the lighting device 17 is inserted with the base support part 16c from the opening 13a on the one end part side of the main body 13 with the base support part 16c formed on the other end side facing down. Further, it is inserted and pushed through the opening 13 b on the other end side, and protrudes from the other end side of the main body 13. As a result, the protrusion 16e of the insulating case 16 is fitted and supported in the support groove 13d of the main body 13 using the elasticity of the resin. You may fix further with the adhesive agent which consists of a silicone resin, an epoxy resin, etc.

  Then, the electric wire c connected to the output terminal of the circuit board 17b is led out from the opening 16a on one end side of the insulating case 16 and connected to the LED 11 of the board 12b constituting the light emitting unit 12 via a connector.

  Further, as described above, the resin ring 15 is attached to the other end side of the insulating case 16 protruding from the opening 13b on the other end side of the main body 13, that is, the base support portion 16c. First, the resin ring 15 will be described. As shown in FIG. 1, the resin ring 15 is configured as a ring made of a synthetic resin having electrical insulation, which is a white PBT resin in the present embodiment. The inner diameter of the ring is configured to fit into the base support portion 16c of the insulating case 16, and the outer shape is such that the outer diameter is successively reduced in succession to the outer surface of the opening 13b on the other end side of the main body 13. To form.

  Then, the ring surface side 15a, in this embodiment, has a ring outer surface with a small diameter, on the side where the cap member 14 described later is provided, at a position shifted by a dimension t1 from the center o of the ring, and a straight line a A pair of concave grooves as the position restricting member 15b is integrally formed at a position that is substantially linear along -a. Then, a body positioning hole 15b1 is formed in one of the concave grooves 15b. The body positioning hole 15b1 is centered on the axis xx of the body 13 when the light emitting portion 12, the insulating case 16, and the lighting device 17 are assembled into the body 13 by the automatic machine after the resin ring 15 is assembled into the body 13. It is a hole for positioning in the direction of rotation. The positioning hole 15b1 may be a hole that penetrates the resin ring 15 or a hole that does not penetrate. In the case of a through-hole, a hole for releasing the internal pressure in the lamp may also be used.

  Also, as shown in FIG. 3, on the back side 15 c of the resin ring 15, in this embodiment, the ring outer surface having a large diameter and connected to the opening 13 b on the other end side of the main body 13, Three ring positioning recesses 15c1 are formed by cutting out. The ring positioning recess 15c1 is a recess for positioning in the rotational direction around the center o of the resin ring when the resin ring 15 is assembled into the main body 13 by an automatic machine. The resin ring 15 is positioned with respect to the main body 13 by being fitted into three convex portions 13b1 (only two are shown) formed integrally on the opening end face of the opening 13b. At the same time, the resin ring 15 is prevented from rotating in the mounted state.

  In addition, after the resin ring 15 is fitted to the base support portion 16c of the insulating case 16, it may be fixed with an adhesive made of silicone resin or the like. Further, instead of the adhesive, a screw portion may be formed on the inner peripheral surface of the resin ring 15 and the outer peripheral surface of the base support portion 16c, and the resin ring 15 may be screwed and fixed to the base support portion 16c. According to this, the insulating case 16 can be drawn to the main body 13 by screwing the resin ring 15, the fixing of the insulating case 16 to the main body 13 without using an adhesive, and the fixing of the resin ring 15 to the insulating case 16. Can be performed simultaneously.

  As described above, the base member 14 is attached to the distal end portion of the base support portion 16 c in a state where the resin ring 15 is fitted to the base support portion 16 c of the insulating case 16. First, the base member will be described. As shown in FIG. 2, the base member 14 is an Edison type base. In this embodiment, the base member 14 is formed of an E26 type similar to an existing general incandescent bulb, and has a conductive metal with a thread. In the embodiment, a cylindrical shell portion 14a made of a copper plate and an eyelet portion 14c provided at the top of the lower end of the shell portion via an insulating portion 14b are provided.

  And the opening part of the shell part 14a is inserted with respect to the screw part 16c1 of the nozzle | cap | die support part 16c protruded from the other end part side of the main body 13, and it supports by screwing in a screw thread. By this screwing, the lower surface side (front surface side 15a) of the resin ring 15 is pressed with the opening end surface of the shell portion 14a, and the upper surface side (back surface side 15c) of the resin ring 15 is brought into contact with the opening end portion of the opening portion 13b of the main body 13. Can be pressed down. Accordingly, the base member 14 is mounted on the other end side of the insulating case 16 so that the base member 14 is provided on the other end side of the main body 13, and the electrical connection between the aluminum main body 13 and the copper plate base member 14 is performed. Insulation is achieved. At this time, an input line previously derived from the input terminal of the circuit board 17 b is connected to the base member 14.

  In the figure, reference numeral 18 denotes a cover member that constitutes a lamp glove, which is made of a material such as thin glass or synthetic resin, and is translucent, such as milky white having transparency or light diffusibility, and milky white in this embodiment. It is formed on a surface that forms a smooth substantially hemispherical object that approximates the silhouette of the bowl portion of a general incandescent bulb that is made of polycarbonate and has an opening 18a at one end. Then, an opening 18a is fitted into the step portion of the substrate support portion 13c of the main body 13 so as to cover the light emitting portion 12, and is fixed with an adhesive made of silicone resin, epoxy resin, or the like. Thus, the inclined outer peripheral portion of the main body 13 has an external shape that is substantially continuous with the curved outer peripheral surface of the cover member 18, and the entire lamp has an external shape that approximates the silhouette of a general incandescent bulb. A lamp 10 with a base is formed.

  Next, an assembly procedure of the lamp with cap 10 configured as described above will be described. Each assembly process shown below is performed by an automatic machine for mass production. First, the insulating case 16 is assembled in the main body 13. That is, the base support part 16c of the insulating case 16 is inserted from the opening 13a on one end side of the main body 13, and is inserted into the opening 13b on the other end side to push the base support part 16c of the push-in insulating case 16 into the main body 13. It protrudes from the other end side.

  Next, the resin ring 15 is fitted into the opening 13b on the other end side of the main body 13 (FIG. 3). At this time, the resin ring 15 has a predetermined position with respect to the main body 13, that is, the three protrusions 13 b 1 integrally formed on the opening end surface of the opening 13 b of the main body 13. It is necessary to assemble by an automatic machine so that the three ring positioning recesses 15c1 can be fitted. Therefore, as shown in FIG. 3, it is necessary to position the resin ring 15 with the center “o” as the center of rotation and automatically convey the resin toward the main body 13.

  This automatic conveyance is performed as follows. The automatic machine shown in FIG. 4 is a small and relatively inexpensive parts conveying device (part feeder) 20, which includes a cylindrical bowl 21 and a linear feeder 22 having a bowl shape. The linear feeder 22 has a cylindrical bowl at one end. The component inlet portion 22a is configured by being continuously arranged at 21, and the other end portion is configured to form a straight line, and a component discharge port 22b for discharging the selected component is formed at the end portion. Is done. Further, in the linear portion of the linear feeder 22, a first sorting unit 22c that sorts the front and back of the parts and a second sorting unit 22d that sorts the front-rear direction with respect to the transport direction are arranged. The first sorting section 22c that sorts the front and back of the parts is sorted by means such as weight balance in the resin ring 15. In the figure, reference numeral 22c1 denotes a discharge tray for discharging the repelled resin ring in the first sorting section.

  Further, the second sorting unit 22d for sorting the front-rear direction is configured as follows. That is, as shown in FIGS. 4B, 4 </ b> C, and 4 </ b> D, a linear guide rail 22 e protrudes from the bottom surface of the linear feeder 22. The width dimension w1 of the bowl-shaped linear feeder 22 is slightly larger than the outer diameter dimension Φ1 of the resin ring 15 (w1> φ1), so that the resin rings can move along the guide rails 22e one by one. The guide rail 22e is formed at a position shifted to one side from the longitudinal center line zz of the bottom surface of the rectilinear feeder 22. The displacement dimension t2 is configured to have a dimension that is substantially the same as the dimension t1 obtained by shifting the pair of concave grooves 15b constituting the position regulating member of the resin ring 15 from the center o of the resin ring 15 (t1≈t2). Moreover, the height dimension and the width dimension of the guide rail 22e are formed such that the concave grooves 15b as the pair of position regulating members of the resin ring 15 are loosely fitted.

  Thereby, the resin ring 15 is conveyed to the linear feeder 22 one by one, and the front / rear direction with respect to the resin ring conveying direction, that is, the concave groove 15b shifted to one side matches the guide rail 22e shifted to one side. A thing fits into the guide rail and is conveyed toward the component discharge port 22b on the guide rail in the fitted state. In the drawing, 22d1 is a discharge tray for discharging the repelled resin ring in the second sorting section.

  The bowl 21 accommodates a large number of parts, in the present embodiment, a large number of resin rings 15 regardless of the front and back sides and the orientation, and the bowl 21 and the linear feeder 22 are vibrated by a vibrator. Due to this vibration, a large number of resin rings 15 vibrate and move in the bowl 21, and one resin ring 15 from the bowl 21 to the component inlet portion 22 a of the linear feeder 22 is related to the front, back, front and back directions. It is conveyed without. The transported resin ring is first screened by the first sorting section 22c. In order to select the front and back surfaces, the rear surface side 15c having the ring surface with a large diameter of the resin ring 15 is the upper surface, in other words, the pair of concave grooves 15b constituting the position regulating member of the resin ring 15 are the lower surface. And is transported to the next second sorting section 22d.

  In the second sorting portion 22d, the pair of concave grooves 15b of the resin ring 15 is the lower surface, and the linear guide rails 22e of the resin rings 15 that are conveyed in a state where the front and rear directions are not uniform are arranged. Only the resin ring in which the direction of the linear groove 15b of the resin ring 15 matches and the groove is fitted to the guide rail 22e is conveyed along the guide rail to the component discharge port 22b. The resin ring in which the direction of the linear groove 15b does not match and the groove does not fit into the guide rail is discharged from the discharge tray 22d1. At this time, since the concave groove 15b, which is a substantially linear position regulating member, is formed at a position shifted from the center o of the resin ring 15, the main body positioning hole 15b1 has a predetermined orientation, in the present embodiment, the main body. The positioning hole 15b1 is sorted so as to be behind the transport direction.

  As a result, the pair of concave grooves 15b of the resin ring 15 becomes the lower surface, the main body positioning hole 15b1 is behind the conveyance direction, and the resin ring 15 whose direction in the front-rear direction is determined is conveyed to the component discharge port 22b. As shown in FIG. 3, the resin ring 15 that has been transported to the component discharge port and whose position in the rotational direction is determined is transported to the next step by a gripping arm (not shown) and protrudes from the opening 13 b of the main body 13. The fitting is automatically fitted to the cap support 16c (see the arrow in FIG. 3). The main body 13 is set at a position automatically determined in advance by a chuck, and the three ring positioning concave portions 15c1 of the resin ring 15 are three convex portions formed in the opening 13b of the main body 13. It is securely fitted to 13b1.

  Next, as described above, the circuit board 17b of the lighting device 17 is accommodated in the insulating case 16 in a state where the insulating case 16 is fitted in the main body 13 and the resin ring 15 is fitted in the base support portion 16c. . At this time, since the pair of support grooves 16d of the insulating case 16 are formed so as to be offset from the axis xx, the directions of the insulating case 16, that is, the support grooves 16d of the main body 13 and the circuit board 17b are matched. Is done.

  That is, as described above, the chuck automatically senses the main body positioning hole 15b1 positioned so as to be positioned behind the transport direction of the resin ring 15, and rotates in the rotational direction around the axis xx of the main body 13. Position the orientation. Thereby, the direction of the circuit board 17b can be matched with the support groove 16d, and can be incorporated by an automatic machine. In this step, the electric wire c connected to the output terminal of the circuit board 17b is led out from the opening 16a on one end side of the insulating case 16, and the input line is led out from the opening 16b on the other end side. .

  Next, the electric wire c is connected to the substrate 12 b of the light emitting unit 12, and the back side of the substrate 12 b is brought into close contact with the substrate supporting unit 13 c formed of a smooth stepped portion of the main body 13 and fixed with screws. Next, the input line led out from the opening 16 b on the other end side of the insulating case 16 is connected to the shell portion 14 a and the eyelet portion 14 c of the base member 14.

  Next, the shell part 14a of the base member 14 is screwed into the base support part 16c protruding from the other end side of the main body 13, and the base member 14 is fixed to the base support part 16c. Next, the opening 18a of the cover member 18 is fitted into the substrate support part 13c of the main body 13 so as to cover the light emitting part 12, and fixed with an adhesive.

  As described above, the bulb-shaped lamp 10 with the cap that can replace the existing general incandescent bulb having the LED 11 as the light source and the cap with the E26 type is configured. This lamp with a base is a concave groove 15b which is a substantially linear position regulating member at a position shifted from the center o of the ring with respect to a resin ring 15 which is interposed between the main body 13 and the base member 14 to achieve electrical insulation. When the lamp with cap is assembled by an automatic machine, the resin ring 15 is configured as a lamp with cap that can be reliably transported to a predetermined position. In particular, it is possible to achieve automation using a small and relatively inexpensive component conveying apparatus, and it is possible to provide a lamp with a cap and a lighting fixture that are advantageous in terms of cost.

  Further, since the concave groove 15b, which is a substantially linear position regulating member of the resin ring 15, is formed at a position shifted from the center o of the ring, as shown in FIG. In the case of taking a photograph of a lamp-equipped lamp catalog or the like, it is also possible to take an image in a state excluding the pair of concave grooves 15b by photographing from the direction A in the figure. .

  Next, the structure of the lighting fixture which used as a light source the lamp | ramp 10 with a bulb | ball-shaped cap comprised as mentioned above is demonstrated. As shown in FIG. 5, 30 is an existing downlight type lighting fixture that is embedded in a ceiling surface X of a store or the like and uses a general incandescent bulb having an E26-type base as a light source, and has an opening 31a on the lower surface. It comprises a metal box-like instrument body 31, a metal reflector 32 fitted into the opening, and a socket 33 into which an E26-type base of a general incandescent bulb can be screwed. The reflector 32 is made of a metal plate such as stainless steel, for example, and a socket 33 is installed at the center of the upper surface plate of the reflector 32.

  In the existing lighting fixture 30 for a general incandescent light bulb configured as described above, a light bulb-shaped lamp with a cap 10 using the above-described LED as a light source is mounted instead of the incandescent light bulb for energy saving and long life. That is, since the lamp-shaped lamp with cap 10 has the cap member 14 formed in the E26 shape, it can be directly inserted into the socket 33 for a general incandescent lamp of the luminaire 30.

 Further, the lamp with cap 10 is configured so that the main body 13 has a substantially conical tapered surface and the appearance approximates the silhouette of the neck portion of a general incandescent bulb. Can be inserted smoothly without hitting the reflector 32 or the like, and the adaptability ratio of the light bulb-shaped lamp with cap 10 to the existing lighting fixture is improved. Thereby, the existing downlight can be easily changed to an energy-saving downlight in which the light bulb-shaped lamp with cap 10 using LEDs as a light source is installed. Of course, not only existing fixtures but also newly constructed lighting fixtures can be similarly constructed.

 When power is turned on to the downlight configured as described above, commercial power is supplied from the socket 33 to the lamp 10 with the cap via the cap member 14, and the lighting device 17 operates to output a DC voltage of 24V. . This DC voltage is applied to each LED 11 from the lighting device 17, and a constant direct current is supplied. All the LEDs are turned on simultaneously, and white light is emitted to perform predetermined illumination.

  As described above, in the present embodiment, the position regulating member of the resin ring 15 is formed by the pair of concave grooves 15b, that is, the concave portions, and the guide rail 22e is formed on the bottom surface of the rectilinear feeder 22 to form the convex portion. However, as shown in FIG. 6A, conversely, the position restricting member of the resin ring 15 is formed by a pair of convex portions 15b ′, and the guide rail of the linear feeder 22 is formed. The bottom surface may be formed as a concave groove 22e ', and the convex portion and the concave portion may be fitted. In this case, since the pair of convex portions 15 b ′ project on the surface side 15 a of the resin ring 15, a notch into which the convex portion 15 b ′ is fitted is formed on the opening end surface of the shell portion 14 a of the base member 14. On the other hand, the open end face of the shell portion 14a may be fitted flush.

  Further, although the position restricting member of the resin ring 15 is constituted by a pair of concave grooves 15b, it may be constituted by a single linear concave groove 15b as shown in FIG. 6 (b). Further, although the position regulating member 15b of the resin ring 15 is formed on the front surface side 15a, it may be formed on the back surface side 15c in accordance with the design specifications for assembling. Further, it may be formed on both the front surface side 15a and the back surface side 15c. In short, it suffices if a substantially linear position regulating member 15b is formed at a position shifted from the center of the resin ring 15 on at least one of the front side or the back side.

  Furthermore, in the present embodiment, the lamp with cap 10 is configured to approximate the shape of an existing general incandescent bulb, but it is in a bowl shape (G shape), a cylindrical shape (T shape), a reflective shape (R shape), or the like. It may be configured. Further, the present invention is not limited to a lamp with a cap approximated to the shape of an existing incandescent bulb, but can be applied to lamps with a cap having various other external shapes and uses.

  The solid-state light-emitting element 11 is not limited to an LED, and a solid-state light-emitting element using an organic EL or a semiconductor laser as a light source is allowed. The solid light-emitting element is preferably configured to emit white light, but may be configured to be red, blue, green, or a combination of various colors depending on the use of the luminaire used. The shape of the light emitting unit 12 may be a polygonal shape such as a circle, a quadrangle, a hexagon, or an ellipse to form a point or surface module, and obtain a desired light distribution characteristic. All shapes are acceptable.

  The main body 13 is made of aluminum having good thermal conductivity, but may be made of a metal containing at least one of copper (Cu), iron (Fe), and nickel (Ni). Moreover, although the main body 13 is preferably made of aluminum die-casting when it integrally has the heat radiating fins 13e as in the above embodiment, it does not necessarily have to have the heat radiating fins. In this case, the main body can be formed by drawing a metal plate such as aluminum.

  The base member 14 is supported by being screwed into the base support part 16c of the insulating case 16, but may be supported by simply fitting the shell part 14a without forming the screw part 16c1 of the base support part 16c. Good. Further, the base member 14 may be supported by caulking, an adhesive or the like in order to make the fixing more firm. The base member 14 is preferably an Edison type E26 type or E17 type or the like that is most commonly used. Further, the material may be a resin base in which the entire base is made of metal, or an electrical connection portion is made of a metal such as a copper plate and the other portion is made of a synthetic resin. Furthermore, it may be a base member having a pin-shaped terminal or a base member having an L-shaped terminal, and is not limited to a specific base member.

  The lighting device 17 may be all accommodated in the insulating case 16 or may be partially accommodated in the base member 14. In addition, as described above, the lighting device 17 is preferably built in the light bulb so that it can be replaced with an existing general incandescent light bulb as it is, but the lighting device is not like a compact fluorescent lamp. It may be configured to be provided separately on the appliance side where the lamp is mounted and not to be built in the bulb side. The lighting device 17 may have a dimming function or a toning function for dimming the solid light emitting element 11.

  Further, in this embodiment, the lighting fixture can be directly attached to the ceiling, suspended, wall-mounted, or embedded in the ceiling, and the fixture body has a glove, shade, reflector, etc. as a light control body.
