Description

  The present invention relates to a lamp-integrated lighting device having a lamp such as a discharge lamp and a lighting circuit for lighting the lamp.

Conventionally, as this type of lamp-integrated lighting device, for example, a bulb-type fluorescent lamp having a base that can be attached to a socket of a general lighting bulb such as an incandescent bulb is known.
JP, 2003-109402, A As shown in the above-mentioned patent documents 1, this bulb-type fluorescent lamp is constituted by a base 9, a lighting circuit 7, and a fluorescent lamp 2, and a circuit board 13 on which components of the lighting circuit 7 are mounted. Is attached to a holder 3 provided in the cover 4, and a fluorescent lamp 2 is attached to the holder 3.

  Further, one end of the cover 4 is attached to the base 9, and the other end of the cover 4 is attached with a globe 6 covering the fluorescent lamp 2.

  Among the plurality of components mounted on the circuit board 13, the electrolytic capacitor 14, which is a relatively large component, is attached to one side of the holder 3 so as to be located inside the base 9, and the other side of the holder 3 Is equipped with a fluorescent lamp 2.

  The conventional bulb-type fluorescent lamp configured as described above requires the cover 4 for supporting the circuit board, and the cover 4 is a light source for enhancing the commercial value so that internal components and the like cannot be seen from the outside. It is composed of a heat-resistant synthetic resin that does not pass through.

  For this reason, some of the circuit components can be stored in the base as described above, but many of the components are difficult to be stored in the base because of the large size and the large number of components.

For this reason, the size of the cover that accommodates multiple parts increases, and the overall size of the bulb-type fluorescent lamp increases. Therefore, further downsizing to approximate the silhouette of a general incandescent bulb, and the light distribution of a general incandescent bulb It is a hindrance factor to approximate the distribution.
JP, 2003-151306, A Furthermore, although there is what is shown in the above-mentioned patent documents 2 as conventional technology, this content is for lighting a light emitting diode and substrate 10 which arranged a light emitting diode which is a light emitting part. The circuit board is mounted with two boards 20 mounted thereon.

  Of the two substrates, the substrate 20 is incorporated under the bulb base, and the substrate 10 is built up on the mouth opening side. The purpose is to make it easier to manufacture.

  According to this configuration, since the circuit components are housed in the base, it is possible to improve the problem that hinders downsizing. However, the two substrates are simply inserted and stored in the base for the light bulb. As a result, there is no support structure for fixing the two substrates in the base, and the two substrates may not be fixed to the base, which may cause rattling, resulting in a problem that causes failure.

  Furthermore, since the light emitting diode as the light emitting portion is arranged in one direction in the base, the directivity is narrow, and the light from the light emitting diode is irradiated in one direction. However, the light distribution may be non-uniform. Further, when a light emitting diode having a relatively wide directivity is used, a part of the light is blocked by a metal base, and there is a problem that it is difficult to effectively use the light of the light emitting portion.

  In this embodiment, in place of the mounting means by the convex part for supporting the circuit board provided in the opening of the base in the first embodiment, the circuit board is supported and attached to the base using a spiral groove on the inner surface of the base. It is what I did.

  4 (a), 4 (b), and 4 (c), 40 is an adapter for attaching the circuit board 15 to the spiral groove 11b of the base 11, and has flexibility such as synthetic rubber or synthetic resin, and A ring-shaped groove 40a is formed on the entire circumference of the inner surface of the ring, and the periphery of the disk-shaped circuit board 15 is fitted into the groove 40a.

  The diameter dimension of the circuit board 15 having a disk shape is smaller than the inner diameter dimension of the base 11, the adapter 40 is fitted to the periphery of the circuit board 15, and the diameter dimension of the disk including the adapter 40 is determined by the circuit board. 15 is configured to be dimensioned so that it can be screwed into the spiral groove 11 b of the base 11 via the adapter 40.

  Reference numeral 41 denotes a protrusion formed by a punch on the inner surface of the base 11 and serves as a stopper when the circuit board 15 is screwed into the spiral groove 11b.

  In the assembly method according to the present embodiment, first, a relatively large component arranged on the lower surface of the circuit board 15 on which the circuit component 12 is mounted is inserted from the opening of the base 11 so that the relatively large part is accommodated in the space 11 a of the base 11. Then, the circuit board 15 is rotated using a jig or the like, the outer peripheral edge of the adapter 40 of the circuit board is screwed along the spiral groove 11b on the inner surface of the base 11, and the peripheral edge of the lower surface of the circuit board 15 is the upper end of the protrusion 41 serving as a stopper. Screw in until it hits.

  At this time, since the adapter 40 is made of a flexible material, the adapter 40 is screwed so as to be pushed in while being rotated.

  In this state, the circuit board 15 is securely supported and attached to the base 11 while being joined to the spiral groove 11 b of the base 11 using the flexibility of the adapter 40.

  At this time, since the adapter 40 is formed of an electrical insulating material such as synthetic rubber or synthetic resin, electrical insulation between the base 11 and the wiring of the circuit board 15 and circuit components is performed.

  In the present embodiment, as shown in FIG. 4B, a male screw portion 42 that is screwed into the spiral groove 11 b of the base 11 may be formed on the outer peripheral edge portion of the adapter 40.

  Further, the adapter 40 may be provided in a ring shape, and a plurality of strip-shaped adapters may be provided on the peripheral edge of the circuit board 15, without being provided on the entire periphery of the peripheral edge of the circuit board 15.

  At this time, the wiring and circuit components are arranged avoiding the outer peripheral edge of the board so that the charging part such as the wiring of the circuit board 15 does not contact the inner surface of the base 11, or an electrical insulating material is coated on the outer peripheral edge of the board. Thus, it is preferable to prevent an electrical short circuit phenomenon. In addition, when the electrical insulating film described in FIG. 8B in the fifth embodiment described later is formed on the inner wall surface of the base 11, this insulating film has already achieved electrical insulation between the base 11 and the circuit board 15. Since it is configured, it is not necessary to perform special electrical insulation treatment on the circuit board 15, and electrical insulation between the base 11 and the circuit board 15 can be ensured reliably.

  Furthermore, as shown in FIG. 4C, even when the circuit board 15 is directly screwed into the spiral groove 11b, for example, when the circuit board 15 is not in a disc shape, for example, a semi-disc shape with a part of the disc cut out, When the shape is such that it cannot be supported, the ring-shaped adapter 40 may be fitted to the peripheral edge of the semicircular circuit board 15 and screwed into the spiral groove 11b via the adapter 40. .

  Other configurations and operations are the same as those of the first embodiment.

  According to the present embodiment, since the circuit board is attached using the spiral groove of the base, it is only necessary to screw the circuit board into the base without performing special processing, and in a simple and inexpensive manner, The circuit board can be securely attached to the base.

  Further, an adhesive 14 d is applied to the upper end of the opening of the base 11 assembled as described above and the outer surface of the globe 14.

  In this state, the circuit board 15 is supported by frictional engagement with the inner surface of the base 11, and the globe 14 is securely supported and attached to the base 11.

  According to this structure, compared with the support structure of the globe 14 in the first embodiment, the ring-shaped attachment portion 16d for attaching the fitting edge portion 14a of the globe 14 to the support member 16 is not necessary, and the support is supported. The structure of the member 16 is simplified. Furthermore, since the attachment portion 16d of the support member 16 is not required, the opening of the globe 14 can be directly attached to the inner surface of the base 11 without using a separate member, and the globe 14 and the base 11 are included. The height dimension of the entire bulb can be further reduced.
