  The present invention relates to a lighting circuit unit, a lighting lamp, and a lighting device for filling a filling member for the purpose of cooling or insulating a lighting circuit without interfering with the function of a pressure valve (synonymous with a safety valve and an explosion-proof valve, hereinafter the same) of an electrolytic capacitor. And a method of manufacturing a lighting circuit unit.

  Conventionally, as a disclosure example of a filling member filling technique for the purpose of cooling or insulating an electronic circuit, there are Patent Documents 1 to 3 and the like. In addition, the filling member is used as a general term for at least one of thermal conductivity and insulation.

The contents using the barrier are described.

  Patent Document 3 discloses an explosion-proof valve side of an electrolytic capacitor as a method of resin-sealing a control board on which an electronic circuit is placed without using a filling member (urethane resin material) without interfering with the function of the pressure valve of the electrolytic capacitor. A method is disclosed in which a cap is crowned on the end of the head.

Japanese Patent No. 4421177 (refer to claim 1, FIG. 1 etc.) Japanese Patent Laying-Open No. 2007-274751 (refer to Claims 1, 2, FIG. 2, etc.) JP 2001-041499 A (refer to claims 1, 3, 6, FIG. 1, 4, 5, 8, 10, etc.)

  The light source 1 includes a light emitting diode (hereinafter referred to as LED) 10 which is a light emitting means, and an LED substrate 11 on which the LED 10 is placed. The light source 1 is attached to one end side (front end side) of a metal casing 31 of the casing section 3 to be described later. The components of the light source 1 include wiring members (not shown) such as a wire harness and a connector (not shown) that are electrically connected to the lighting circuit 5 and transmit drive power from the lighting circuit 5 to the light source 1. In addition, the components of the light source 1 include attachment members such as screws (not shown) for attaching the LED substrate 11 to the housing unit 3, and electronic components required according to the design specifications of the illumination lamp 100. It is.

  In the first embodiment, the LED 10 is described as an example of the light emitting unit, but the light emitting unit is not limited to the LED 10. In addition to the LED 10, a laser diode, an organic EL, a fluorescent lamp, or the like may be used as the light emitting means.

The globe 2 is configured by curving a material such as glass or resin, and is attached to one end side (front end side) of the metal casing 31 so as to cover the light source 1. As the resin, for example, polycarbonate or acrylic can be selected according to the product specifications.
The globe 2 has translucency and transmits light emitted from the light source 1. In addition, the globe 2 may have a function of diffusing, condensing, and reflecting light emitted from the light source 1 as necessary.
These functions may be applied directly to these substrates as a diffusion layer (or surface), a lens, a reflective layer (or surface), etc., when the glass or resin that is the substrate of the globe 2 is molded. You may comprise combining another member on the surface of a material.

The lighting circuit 5 includes an electrolytic capacitor 501 and a circuit board 502 including an AC-DC converter circuit that converts input AC power, which is commercial power, into direct current that drives the LED 10. That is, the lighting circuit 5 has a function of converting the commercial power input from the base unit 4 into driving power for driving the light source 1 and supplying the driving power to the light source 1.
Preferably, in order to drive the LED 10 stably, a load fluctuation detection function, a control function for controlling the drive current output from the AC-DC converter circuit according to the load fluctuation, It is preferable to further have a filter function for removing or reducing noise that flows out. In addition, when using means other than LED as the light emission means of the light source 1, an optimal lighting circuit is used for each.

The electrolytic capacitor 501 has a function of smoothing input commercial power and reducing a pulsating flow of driving power supplied to the light source 1 in order to drive the LED 10 that is a light emitting unit of the light source 1. . By providing the electrolytic capacitor 501, stable direct-current power can be supplied to the light source 1, and stable light emission can be realized. The electrolytic capacitor 501 is housed in a case made of, for example, aluminum. These are collectively referred to as an electrolytic capacitor 501. The electrolytic capacitor 501 has a pressure valve 503. Specifically, the pressure valve 503 is formed on one surface of the case in which the electrolytic capacitor 501 is accommodated.
The external dimensions of the electrolytic capacitor 501 depend on the capacitance value and voltage specification of the electrolytic capacitor 501 determined according to the design specification of the illumination lamp 100.

  In addition, the electrolytic capacitor 501 is included in the inner space of the housing 3 (specifically, the resin housing 30) on the base 4 side. This is suitable when considering the dimensional restrictions associated with the miniaturization of the illumination lamp 100 and the purpose of improving the operational reliability of the electrolytic capacitor 501 by being separated from the light source 1 as the main heat source. Arrangement.

In the case where the light source 1 has a light emitting means other than the LED, etc., the electrolytic capacitor 501 may have other uses and functions, but the detailed description is omitted.

  FIG. 2 is an enlarged cross-sectional view showing an enlarged configuration of the main part in a state where the metal casing 31, the light source 1, and the globe 2 are removed from the illumination lamp 100 shown in FIG. FIG. 3 is an enlarged cross-sectional view showing a state in which a filling member 6 and a separating member (cover) 7 are schematically added to the enlarged cross-sectional view of the illumination lamp 100 shown in FIG. Based on FIG.2 and FIG.3, the structure used as the premise of the illumination lamp 100 is demonstrated in detail.

  As shown in FIG. 2, a pressure valve 503 is provided on one end surface of the electrolytic capacitor 501. The pressure valve 503 operates so as to open a part of the electrolytic capacitor 501 when the internal pressure of the electrolytic capacitor 501 becomes higher than a preset threshold value according to a change in environmental conditions such as high temperature. When the pressure valve 503 opens a part of the electrolytic capacitor 501, the high-pressure gas inside the electrolytic capacitor 501 moves to the outside, so that the internal pressure of the electrolytic capacitor 501 decreases.

The pressure valve 503 is provided so as to face the housing inner surface 8 of the resin housing 30. The gap D between the pressure valve 503 and the housing inner surface 8 is set to a distance that does not hinder the function (operation (opening)) of the pressure valve 503. That is, the gap D is defined by component specifications such as the outer dimensions of the electrolytic capacitor 501 and the dimensions of the pressure valve 503, the mounting position of the electrolytic capacitor 501 on the circuit board 502, the lead forming dimensions of the electrolytic capacitor 501, and the resin casing 30. It is set in consideration of design specifications such as a holding structure (not shown) for holding the circuit board 502 to be formed.
Note that the gap D is the distance between the pressure valve 503 and the opposing surface of the pressure valve 503 of the isolation member 7 when the isolation member 7 is attached.

As shown in FIG. 3, the illumination lamp 100 includes a filling member over substantially the entire circumference of the gap portion between at least a part of the outer surface of the circuit board 502 including the electrolytic capacitor 501 and the housing inner surface 8 of the resin housing 30. 6 is disposed.
The filling member 6 is made of a material having at least one of thermal conductivity and insulation.

  Here, the surface of the electrolytic capacitor 501 having the pressure valve 503 is covered with a separating member (cover) 7. One end of the isolation member 7 is attached to the outer surface (cylinder peripheral portion) of the electrolytic capacitor so as to cover the pressure valve 503 so that one end does not hinder the function (operation (opening)) of the pressure valve 503. Retained. Further, the isolation member 7 is held in contact with the cylindrical peripheral portion of the electrolytic capacitor 501 with a gap having a predetermined volume that does not hinder the function (operation (opening)) of the pressure valve 503.

  In other words, by providing the isolation member 7, the filling member 6 does not enter the gap formed by the isolation member 7 and the pressure valve 503. For this reason, even if abnormal operating stress (operating temperature, operating current, etc.) is applied to the electrolytic capacitor 501, the opening operation of the pressure valve 503 is not hindered. Even if the pressure valve 503 is opened and the electrolyte leaks out of the electrolytic capacitor 501, the isolation member 7 shields the electrolyte, and the electrolyte remains in the gap formed by the isolation member 7.

  The attachment may be direct attachment to an aluminum case covering the electrolytic capacitor 501 or indirect attachment via a vinyl sleeve or the like. The outer surface to which the isolation member 7 is attached may be any outer surface of the electrolytic capacitor 501 as long as the function (operation (open)) of the pressure valve 503 is not hindered. For example, the isolation member 7 may be attached to the outer surface of the pressure valve 503.

  FIG. 4 is an explanatory diagram for explaining the relationship between the isolation member 7 mounted on the illumination lamp 100 and the electrolytic capacitor 501. FIG. 5 is an explanatory diagram for explaining an example of the separating member 7 mounted on the illumination lamp 100. The details of the isolation member 7 will be described based on FIGS. 4 and 5, and the relationship between the isolation member 7, the electrolytic capacitor 501, and the pressure valve 503 will be described. 5A is a schematic view showing a state in which the separating member 7 is viewed from the side, and FIG. 5B is a state in which the CC cross section of FIG. FIG.

  As shown in FIG. 5A, the isolation member 7 has an isolation part 70 and a contact part 71. The isolation part 70 has a function as a boundary that isolates the inner space of the isolation member 7 and the outer space of the isolation member 7. The attachment part 71 is joined to the cylindrical peripheral part of the electrolytic capacitor 501. The isolation member 7 has an inner space secured by the isolation part 70 b and is joined to the electrolytic capacitor 501 via the attachment part 71. The attachment part 71 increases the rigidity by thickening the periphery of the opening of the isolation member 7.

  The isolation member 7 is attached so as to cover the pressure valve 503 of the electrolytic capacitor 501 before the lighting circuit 5 is held in the internal space of the housing 3. When attaching the separating member 7, the attachment portion 71 is attached to the cylindrical peripheral portion of the electrolytic capacitor 501. By doing so, the isolation member 7 is held by the electrolytic capacitor 501. Further, the isolation member 7 can be held by the casing inner surface 8 of the resin casing 30 on the outer surface (the outer surface that is not on the electrolytic capacitor 501 side) while being attached to the cylindrical peripheral portion of the electrolytic capacitor 501. Yes.

The isolation member 7 is composed of a member having elasticity (for example, a member such as resin or rubber). By doing so, the separating member 7 can be in close contact with both the outer surface of the electrolytic capacitor 501 and the inner surface 8 of the resin housing 30.
In addition, the isolation member 7 should just have elasticity, and may have either volume elasticity or shape elasticity.

  By attaching the separating member 7, the internal space of the resin housing 30 is separated into two shielded spaces (the inner space of the separating member 7 and the outer space of the separating member 7) with the separating member 7 as a boundary. become. That is, the internal space of the resin casing 30 includes a first internal space in which the pressure valve 503 of the electrolytic capacitor 501 that is the inner space of the isolation member 7 is enclosed, and an electrolytic capacitor 501 that is the outer space of the isolation member 7. The pressure valve 503 is separated into a second internal space that is not included.

  Therefore, the filling member 6 is filled only in the second internal space from the second internal space side. Therefore, the heat generated from the AC-DC converter circuit of the circuit board 502 and the heat generated from the light source 1 are transmitted from the filling member 6 through the resin housing 30 and the metal housing 31 to the illumination lamp 100. It will be transmitted to the outside. That is, cooling of the light source 1 and the lighting circuit 5 is promoted.

  Further, since the first internal space is separated and shielded from the second internal space by the isolation member 7 as a boundary, the filling member 6 enters the first internal space beyond the isolation member 7. There is no. That is, even if the filling member 6 is filled in the internal space of the resin casing 30 in which the lighting circuit 5 is enclosed, the filling member 6 does not enter the pressure valve 503 of the electrolytic capacitor 501 contained in the first internal space. For this reason, the function of the pressure valve 503 of the electrolytic capacitor 501 is not disturbed.

  As described above, the illumination lamp 100 is provided with the isolation member 7, so that the pressure valve of the electrolytic capacitor 501 is filled even when the filling member 6 is filled for cooling the lighting circuit 5 including the light source 1 and the electrolytic capacitor 501. The filling member 6 does not enter 503. For this reason, according to the illumination lamp 100, the function of the pressure valve 503 of the electrolytic capacitor 501 is not disturbed. Of course, since the cooling effect of the lighting circuit 5 including the light source 1 and the electrolytic capacitor 501 is maintained, the operational reliability and life of the electrolytic capacitor 501 can be improved, and the operational quality of the illumination lamp 100 can be ensured.

  Note that the contact portion 71 of the isolation member 7 is not limited to the shape and size shown in FIGS. 4 and 5 as long as the adhesion to the electrolytic capacitor 501 can be secured. Further, for the purpose of reliably holding the separating member 7 on the electrolytic capacitor 501, the separating member 7 may be attached to the electrolytic capacitor 501 as appropriate using an adhesive member (adhesive or the like).
