The transmitted blue light and yellow light are mixed to emit white light. The light emitting module 13 a configured as described above is disposed on the substrate 13 b to constitute the light emitting unit 13. The substrate 13b also serves as a heat radiating member, and is composed of a member having good thermal conductivity, in the present embodiment, made of aluminum having a relatively thick plate shape, and emits light to a flat central portion. The module 13a is fixed in close contact by a fixing means such as a screw, and heat generated from each LED 12 is transmitted from the wiring board 12a1 to the board 13b. The wiring board 12a1 may be formed integrally with the board 13b. In this case, the thermal conductivity becomes better and the heat dissipation becomes better. Thereby, the light emission part 13 by which LED12 which is a solid light emitting element is arrange | positioned so that a substantially square surface may be comprised is comprised.

  The light emitting unit 13 configured as described above is accommodated and installed in the main body 11. That is, the back surface side of the substrate 13b is brought into close contact with the substrate support portion 11c composed of a flat plate-shaped step portion, and is supported and fixed by a fixing means such as a screw. As a result, the heat of the LED 12 transmitted from the wiring board 12a1 to the board 13b is further transmitted to the aluminum main body 11 to be radiated to the outside. In addition, the board | substrate 13b may be formed integrally with the main body 11, and in this case, thermal conductivity becomes better and heat dissipation becomes better.

That is, the insulating case 15 is configured as a cylindrical body having both ends formed of a synthetic resin having electrical insulation, that is, a PBT resin in this embodiment. The opening 15a on one end side of the cylindrical body is disposed so as to face the back side of the substrate 13b of the light emitting unit 13, and an electric wire (not shown) connected to the output terminal of the lighting device 14 is inserted therethrough. .

  A base support portion 15c is integrally formed in the opening 15b on the other end side of the cylindrical body, and a screw portion 15c1 is integrated so that a base member 16 (to be described later) can be screwed into the outer peripheral surface of the base support portion 15c. To form. A support groove 15d (FIG. 3) consisting of a pair of vertical grooves for supporting the lighting device is integrally formed in the vertical direction on the inner peripheral surface of the cylindrical body, and is fixed to the main body 11 at the outer peripheral portion of the cylindrical body. Support step 15e and packing, in this embodiment, a support recess 15g made of a ring-shaped lateral groove for fitting the O-ring 15f is integrally formed.

  The insulating case 15 configured as described above houses the lighting device 14 therein, and the base member 16 is attached to the base support portion 15c. First, the lighting device will be described. As shown in FIG. 1, the lighting device 14 includes a circuit component 14a constituting a lighting circuit of each LED 12, and a circuit board 14b 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 12. The circuit board 14b is made of a glass epoxy material having a strip shape, and a circuit component 14a made of an electronic component is mounted on one side or both sides of the circuit board 14b. The circuit board 14b is formed in a longitudinal direction and a pair of support grooves formed on the inner surface of the insulating case 15 By inserting and fitting in 15d (FIG. 3), the lighting device 14 is accommodated in the vertical direction inside the insulating case 15 and supported. An electric wire is connected to the output terminal of the circuit board 14b, and an input line (not shown) connected to the base member 16 is connected to the input terminal.

  In addition, as shown in FIG. 1, the base member 16 is an Edison-type base, and in this embodiment, the base member 16 is made of an E26 type similar to an existing reflective incandescent bulb, and has a conductive metal with a thread. In this embodiment, a cylindrical shell portion 16a made of a copper plate and an eyelet portion 16c provided at the top of the lower end of the shell portion via an insulating portion 16b are provided. Then, the opening portion of the shell portion 16a is fitted into the screw portion 15c1 of the base support portion 15c in the insulating case 15 and is supported by screwing a screw thread. Thereby, the base member 16 is attached to the other end side of the insulating case 15, and electrical insulation between the aluminum main body 11 and the base member 16 is achieved. At this time, an input line previously derived from the input terminal of the circuit board 14 b is connected to the base member 16.

  As described above, the filler 17 is filled in a state where the lighting device 14 is accommodated in the insulating case 15 and the cap member 16 is mounted on the other end side. The filler 17 is a synthetic resin such as a silicone resin or an epoxy resin that has electrical insulation and thermal conductivity, has elasticity in a solidified state, and has waterproofness and adhesiveness. In this embodiment, the silicone resin An adhesive consisting of: As described above, the filling is performed in such a manner that the lighting device 14 is accommodated, the base member 16 is mounted on the other end side, and electrical connection between the base member 16 and the lighting device 14 is performed. A filler 17 made of a liquid silicone resin is injected from the side opening 15a. As a result, as shown in FIG. 1, the liquid silicone resin flows in along the inner surface of the cylindrical insulating case so as to cover the circuit component 14a and the circuit board 14b of the lighting device 14 accommodated in the insulating case 15. Furthermore, it flows into the entire space in the shell portion 16 a of the base member 16 from the opening 15 b on the other end side of the insulating case 15. And it inject | pours to the extent that a silicone resin overflows from the opening part 15a of the one end part side of the insulation case 15, and it hardens | cures in a high temperature atmosphere, and is stabilized.

  The filling material 17 is preferably filled in the entire space of the insulating case 15 and the shell portion 16a. However, the filling material 17 may have a space in part instead of filling the entire space. All or a part of the 14 circuit components 14 a and the circuit board 14 b, and the space between the base support portion 15 c of the insulating case 15 and the shell portion 16 a of the base member 16 may be covered and supported by the filler 17. The filling material 17 can be hardened by the insulating case 15 alone including the lighting device 14 and the base member 16 before the insulating case 15 is incorporated into the main body 11, and the work should be performed in a stable state. Can do. By the way, in the state of being incorporated in the main body 11, the main body 11 is large and has a circular shape, so it is not stable and difficult to work.

  Thereby, the circuit component 14a and the circuit board 14b in the insulating case 15 are sufficiently covered with the silicone resin, and the shell portion 16a is also filled with the silicone resin, so that the outside and the inside are waterproof and airtightly separated. The screwed portion between the shell portion 16a of the base member 16 and the base support portion 15c of the insulating case 15 is hermetically sealed and fixed. Thereby, it becomes possible to prevent the intrusion of water, dust or the like from the base member 16 with certainty, and the reliability of the lighting device can be improved.

  Further, since the circuit board 14b is firmly supported by the elastic filler 17 in the insulating case without rattling, there is no risk of component dropping or disconnection of input lines or the like in the shell portion 16a. 14b is embedded with a filler having electrical insulating properties, and the electrical insulating properties are sufficiently maintained, so that higher reliability can be secured.

  Further, the circuit board 14b is fixed by the filler 17 without being press-fitted and fixed to the insulating case 15, so that stress due to the press-fitting is not applied to the circuit component 14a and the circuit board 14b. Reliability can also be improved. At the same time, the heat generated from the circuit component 14a can be transmitted to the base member 16 made of a copper plate via the heat conductive filler 17, and can be effectively radiated to the outside. It becomes possible to increase the sex.

  As a result, it is possible to achieve the fixing of the base member 16 and the waterproof structure of the base member by using the filler for the electrical insulation of the lighting device 14 and also using the filling operation of the filler as it is. . In other words, it is possible to realize the support of the lighting device 14, the fixing of the base member 16, and the waterproof structure of the base member by one operation of injecting one part of the filler and the filler. A lamp 10 with a base using a beam-shaped LED as a light source, which is excellent in weather resistance, waterproofness, and electrical insulation like a light bulb and is particularly suitable for outdoor use, is configured.

  As described above, the insulating case 15 in which the lighting device 14 is accommodated and the base member 16 is attached to the base support portion 15c on the other end side is directed from the irradiation opening 11a on the one end side of the main body 11 with the base member 16 facing downward. Further, it is inserted through the opening 11b having a small diameter on the other end side and protrudes from the other end side of the main body 11. Thus, the base member 16 is provided on the other end side of the main body 11, the support step portion 15 e of the insulating case 15 is placed on the inner peripheral surface of the main body 11, and the support step portion 15 e is the inner peripheral surface of the main body 11. It is fixed by fixing means such as screws.

  At this time, a small convex portion 15 h is integrally formed on the outer peripheral surface on the other end portion side of the insulating case 15, and the outer diameter protruding dimension of the convex portion 15 h is the small opening portion 11 b on the other end side of the main body 11. It is formed slightly larger than the inner diameter. As a result, the insulating case 15 is inserted into the opening 11b on the other end side of the main body 11 by press-fitting, and is locked when the convex portion 15h gets over the opening of the opening 11b, so that the insulating case 15 is attached to the main body 11. On the other hand, it is fixed more firmly. In this case, a screw or the like for fixing the insulating case 15 to the main body 11 may be omitted. As a result, the insulating case 15 can be fixed without using an adhesive or the like for fixing to the main body 11, and there is no trouble such as addition of components or curing of the adhesive, and labor and cost at the time of assembly. It becomes possible to eliminate up.

  Further, the insulating case 15 is inserted by being pushed in against the elasticity of the O-ring 15f in a state where the O-ring 15f is fitted in the support recess 15g formed on the outer peripheral portion thereof. Thereby, the O-ring 15f is in close contact with the inner peripheral surface of the main body 11, and the insulating case 15 and the main body 11 are supported in an airtight state. Then, the electric wire connected to the output terminal of the circuit board 14 b is led out from the opening 15 a on the one end side of the insulating case 15 and connected to the LED 12 of the board 13 b constituting the light emitting unit 13.

  Next, in FIG. 1, 18 is a reflector for controlling the light distribution of the light emitted from the light emitting section 13, and 19 is a cover member forming a glove. First, the reflector will be described. The reflector 18 is made of metal or synthetic resin, in this embodiment PBT resin, and an exit opening 18b having a wide opening for emitting light to one end side so that the reflection surface 18a forms a paraboloid of revolution. The mortar-like shape is integrally formed so as to have an incident opening 18c composed of a small opening on the other end side. The reflection surface 18a is formed on a mirror surface that has been subjected to aluminum vapor deposition finish.

  The reflector 18 configured as described above is supported by the irradiation opening 11 a on one end side of the main body 11. As shown in FIGS. 1 and 2, the irradiation opening 11 a of the main body 11 is integrally formed with an annular step portion 11 a 1 on the inner peripheral side, and this step portion is integrated with a wide emission opening 18 b of the reflector 18. The formed collar portion 18b1 is placed and fixed by fixing means such as a screw. As a result, as shown in FIG. 1, the optical axis of the reflector 18 is aligned with the optical axis xx of the light emitting section 13, and the incident opening 18c of the reflector 18 is disposed so as to surround the entire light emitting module 13a. The light emitted from the light emitting module 13a can be taken in by the incident opening 18c without any optical loss, reflected by the reflecting surface 18a, and emitted from the outgoing opening 18b.

  The cover member 19 constitutes a lamp globe. For example, the cover member 19 is made of a material such as a thick synthetic resin or glass, and is transparent or translucent such as milky white having light diffusibility. In the present embodiment, the cover member 19 is transparent. It is made of acrylic resin and has a shallow basin shape that approximates the silhouette of a globe of an existing reflective incandescent bulb having an opening 19a at one end. Then, as shown in FIG. 2, a threaded portion 19b is integrally formed on the inner peripheral surface serving as the edge of the tray, and packing is performed on the opening edge of the edge, that is, the edge of the opening 19a. An annular concave step portion 19a1 for housing is integrally formed. Furthermore, as shown in FIG. 1, a lens portion 19c made up of a number of convex spherical surfaces is integrally formed on the bottom surface inside the tray.

  The cover member 19 configured as described above is supported by being screwed into the irradiation opening 11 a on the one end side of the main body 11. As shown in FIG. 2, an annular step portion 11a2 is integrally formed on the outer peripheral side of the irradiation opening 11a of the main body 11, and a main body side screw portion 11a3 is integrally formed on the outer peripheral surface of the step portion. An annular concave step portion 11a4 is integrally formed below the side screw portion 11a3, that is, on the shoulder portion of the step portion. The right portion of the lamp with cap 10 facing the portion A in FIG. 1 has the same configuration. Moreover, the cover member 19 may be formed of a peripheral side portion having a screw portion 19b and a bottom surface portion (lens portion 19c in the lamp with cap) as separate members.

  Thus, the opening 19a of the cover member 19 is fitted into the stepped portion 11a2 of the main body 11 so as to cover the light emitting portion 13 and the reflector 18, and the screw portion 19b of the cover member 19 with respect to the main body side screw portion 11a3 of the main body 11. Then, the cover member 19 is fixed to the main body 11. At this time, the cover member 13 is screwed into the main body 11 with the O-ring p fitted in advance into the annular concave step portion 11a4 of the main body 11. This screwing stops when the horizontal surface of the step portion 19a1 of the cover member 19 contacts the step portion 11a2 of the main body 11.

  Thus, the O-ring p is disposed in the space S in which the cross section formed by the O-ring p facing the main body side step portion 11a4 of the main body 11 and the step portion 19a1 of the cover member 19 has a substantially rectangular shape. Then, by screwing the cover member 19 into the main body 11, the O-ring p is compressed and brought into close contact with each inner wall of the rectangular space S, and the cover member 19 and the main body 11 are supported in an airtight state. The

  As shown in FIG. 2, the O-ring p includes two portions (point aa in the drawing) of the concave step portion 19 a 1 of the cover member 19 and a horizontal plane and a vertical plane of the concave step portion 11 a 4 of the main body 11. The two parts (b-b in the figure) are compressed and contacted, so that there are two waterproof and airtight securing portions, which is equivalent to a state where two O-rings are used. The waterproof and airtightness can be secured automatically by an operation of screwing the cover member 19 into the main body 11 without any special operation / work for securing. Thereby, the reliability of waterproof and airtightness is remarkably improved, and even a specification requiring strong waterproof confidentiality can be realized easily and reliably with one O-ring.

  In particular, it is possible to provide a lamp with a cap having a waterproof function equivalent to or higher than that of an existing reflective incandescent lamp in a beam-type lamp with a cap used outdoors. In addition, this type of lamp with a base is used for a long period of time, in which the LED 12 serving as a light source generates heat, the temperature inside the main body 11 rises, and the expansion and contraction are repeated in an environment where the temperature difference from the outside air is severe, such as in winter. Therefore, although the airtightness is likely to be deteriorated, these problems can be solved by employing the above-described cover member mounting device.

  As a result, the outer peripheral portion of the main body 11 formed so as to form a substantially conical tapered surface has an appearance shape that is substantially continuous integrally with the bonnet-shaped cover member 19 constituting the globe, and the entire lamp is existing. A beam-shaped lamp 10 with a base having an external shape and size approximating the silhouette of a reflective incandescent bulb is formed. As shown in FIG. 1, the optical axis of the cover member 19 matches the optical axis xx of the light emitting unit 13 and the reflector 18, and the light emitted from the emission opening 18 b of the reflector 18 is converted into the cover member. The beam-shaped illumination condensed in a predetermined direction by the 19 lens portions 19c can be performed.

  In particular, according to the lamp with cap 10 of the present embodiment, the desired light distribution control can be performed by the optical control function by the translucent cover member 19 having the lens portion 19 c and the optical control function by the reflector 18. it can. For this reason, by selecting the cover member 19 and the reflector 18, it is possible to realize various kinds of light distribution angles. For example, if the cover member 19 and the reflector 18 are lined up with several parts with different light distributions, a beam-type lamp with a base having various light distribution angles can be easily configured by combining them.

  Next, the assembly procedure of the cap-equipped lamp 10 configured as described above will be described with reference to FIG. First, the circuit board 14 b of the lighting device 14 is accommodated in the insulating case 15. At this time, the electric wire connected to the output terminal of the circuit board 14b is led out from the opening 15a on one end side of the insulating case 15, and the input line is led out from the opening 15b on the other end side.

  Next, the input line led out from the opening 15 b on the other end side of the insulating case 15 is connected to the shell portion 16 a and the eyelet portion 16 c of the base member 16. Next, the shell portion 16 a of the base member 16 is screwed into the base support portion 15 c of the insulating case 15. Next, the filler 17 is poured from the opening 15a on one end side of the insulating case 15 to the extent that it overflows from the opening 15a. Next, the filler 17 is cured in a high temperature atmosphere.

  Next, the base support portion 15c of the insulating case 15 to which the base member 16 is attached is inserted from the irradiation opening portion 11a on the one end portion side of the main body 11, and is inserted into the opening portion 11b on the other end portion side. Project from the end side. At this time, the insulating case 15 is inserted by being pushed in against the elasticity of the O-ring 15f fitted in the outer peripheral portion.

  Next, the back surface side of the substrate 13b of the light emitting unit 13 on which the light emitting module 13a is mounted in advance is brought into close contact with the substrate supporting unit 11c formed of a smooth step portion in the main body 11 and fixed with screws. Next, the flange portion 18 b 1 of the reflector 18 is placed on the annular step portion 11 a 1 of the main body 11 and fixed with screws, and the incident opening 18 c of the reflector 18 is opposed to the light emitting module 13 a of the light emitting portion 13.

  Next, the opening 19a of the cover member 19 is fitted into the step portion 11a2 of the main body 11 so as to cover the light emitting portion 13 and the reflector 18, and the screw portion 19b of the cover member 19 is screwed into the screw portion 11a3 of the main body 11. To fix. At this time, it is fixed by screwing in while fitting against the elasticity of the O-ring p.

  As described above, the beam-type lamp 10 with the base that can replace the existing reflective incandescent lamp having the LED 12 as the light source and the base having the E26 type is configured. In the lamp with cap, the mounting portion of the cap member 16 is sealed with the filler 17, the insulating case 15 and the main body 11 are sealed with the O-ring 15f, and the cover member 19 and the main body 11 are sealed with the O-ring p. Is done. The same structure as that of an existing reflective incandescent bulb or the like by simple means such as screwing the cover member 19 into the main body 11 and pushing the insulating case 15 into the main body 11 during the simple construction and assembly by these O-rings. It is configured as a base lamp using a completely waterproof beam-shaped LED having the above waterproof function as a light source.

  Next, the operation of the cap-equipped lamp 10 configured as described above will be described. When the cap member 16 of the lamp with cap 10 is mounted on the socket of the appliance and the power is supplied and turned on, light is emitted from the light emitting module 13a having a substantially square shape of the light emitting portion 13. The emitted light is taken into the incident opening 18c of the reflector 18, reflected by the reflecting surface 18a in a direction substantially along the optical axis xx line, and further, the optical axis xx by the lens portion 19c of the cover member 19. The light is condensed in the direction along the line, and illumination with a light distribution characteristic equivalent to that of an existing reflective incandescent bulb can be performed.

  In addition, when the lamp with cap 10 is installed outdoors and rainwater or the like is applied, the cover member 19 and the main body 11 are securely sealed by the O-ring p, so that water enters the main body 11. There is nothing. Further, the water that has traveled around the outer periphery of the main body 11 does not enter the main body 11 because the insulating case 15 and the main body 11 are sealed by the O-ring 15f. Further, the water transmitted to the base member 16 does not enter the base because the base member 16 is sealed with the filler 17. Like these waters, dust and the like do not enter. Thereby, the completely waterproof lamp 10 with the base is configured by the O-ring p, the O-ring 15 f and the waterproofness and airtightness due to the filler 17.

  Further, when the lamp with cap 10 is turned on, the temperature of the LED 12 rises and heat is generated. The heat is transmitted from the wiring board 12a1 made of aluminum to the board 13b made of aluminum, and is further transferred to the main body 11 made of aluminum to which the board 13b is fixed to be radiated to the outside. This is because the main body 11 is formed so as to form a substantially conical tapered surface, and the outer appearance is configured in a shape that approximates the silhouette of the outer peripheral portion and neck portion of an existing reflective incandescent bulb, and has a heat dissipation effect Has a large area, the heat transferred to the main body 11 is released one after another from the outer peripheral portion, and continuous heat dissipation is performed.
