Description

この発明は、ランプを点灯させる点灯装置に関する。   The present invention relates to a lighting device for lighting a lamp.

照明器具に搭載される放電灯点灯装置は、一般に、回路部品が実装される回路基板がケースで覆われた構造である。
特許文献１，２，３には、金属製のベースケースに回路基板を取り付け、ベースケースに金属製のカバーケースを連結させて、回路基板をベースケースとカバーケースとの間に収納した放電灯点灯装置について記載がある。この放電灯点灯装置では、回路基板に取り付けられた回路部品のリードが回路基板から突出するため、ベースケースと回路基板との間に所定の隙間を空けて、ベースケースに回路基板を取り付けている。 A discharge lamp lighting device mounted on a luminaire generally has a structure in which a circuit board on which circuit components are mounted is covered with a case.
Patent Documents 1, 2, and 3 disclose a discharge lamp in which a circuit board is attached to a metal base case, a metal cover case is connected to the base case, and the circuit board is accommodated between the base case and the cover case. There is a description of the lighting device. In this discharge lamp lighting device, since the lead of the circuit component attached to the circuit board protrudes from the circuit board, the circuit board is attached to the base case with a predetermined gap between the base case and the circuit board. .

特許文献１，２に記載された放電灯点灯装置では、回路基板の長手方向端部付近に端子台が実装され、端子台が実装された部分の回路基板はカバーケースの外側に露出している。そのため、回路基板の長手方向端部では、ベースケースと回路基板との間に空けられた隙間は、カバーケースに覆われていない。その結果、ベースケースと回路基板との間に空けられた隙間に虫等が侵入してしまい、回路充電部が短絡する場合がある。   In the discharge lamp lighting device described in Patent Documents 1 and 2, the terminal block is mounted near the end in the longitudinal direction of the circuit board, and the portion of the circuit board on which the terminal block is mounted is exposed to the outside of the cover case. . For this reason, the gap formed between the base case and the circuit board is not covered with the cover case at the end in the longitudinal direction of the circuit board. As a result, insects or the like may enter a gap formed between the base case and the circuit board, and the circuit charging unit may be short-circuited.

特許文献３に記載された放電灯点灯装置でも、特許文献１，２に記載された放電灯点灯装置と同様に、回路基板の長手方向端部付近に端子台が実装されている。しかし、特許文献３に記載された放電灯点灯装置では、ベースケースの長手方向端部を切り起こして、端子台の一部を外部へ露出させつつ、ベースケースと回路基板との間に空けられた空間を塞いでいる。但し、この放電灯点灯装置の構造では、ベースケースの加工が複雑である。   Also in the discharge lamp lighting device described in Patent Document 3, a terminal block is mounted in the vicinity of the end portion in the longitudinal direction of the circuit board, similarly to the discharge lamp lighting device described in Patent Documents 1 and 2. However, in the discharge lamp lighting device described in Patent Document 3, the longitudinal end portion of the base case is cut and raised so that a part of the terminal block is exposed to the outside, and the gap is provided between the base case and the circuit board. Block the space. However, in the structure of the discharge lamp lighting device, processing of the base case is complicated.

この発明は、例えば、簡単な加工により、回路基板部分への虫などの侵入を防ぐことを目的とする。   An object of the present invention is to prevent insects and the like from entering a circuit board portion by, for example, simple processing.

回路基板３は長方形に形成され、放電灯を点灯する回路部品７が実装される。また、回路基板３には、商用電源から電流が入力される入力用端子台６ａと、放電灯へ電流を出力する出力用端子台６ｂとが設けられる。なお、入力用端子台６ａと出力用端子台６ｂとを総称して端子台６と呼ぶ。
ベースケース５は、ベース板５−１と、ベース板５−１の短手方向の両端部を折り曲げられて形成されたベース側板５−２とを有する。ベースケース５には、回路基板３が取り付けられる。特に、回路基板３の回路部品７が実装された部品実装面の裏側のはんだ面側をベースケース５側に向けて、ベースケース５に回路基板３が取り付けられる。また、ベースケース５のベース板５−１と回路基板３のはんだ面との間には、高さＨ１（図３（ａ）参照）の隙間８が空けられて、ベースケース５に回路基板３が取り付けられる。例えば、ベースケース５のベース板５−１又はベース側板５−２に切り起こしが設けられ、その切り起こしに回路基板３を取り付けることにより、ベース板５−１とはんだ面との間に隙間８が空けられる。
カバーケース１は、カバー板１−１と、カバー板１−１の短手方向の両端部が折り曲げられて形成されたカバー側板１−２と、カバー板１−１の長手方向の両端部が折り曲げられて形成されたカバー端板１−３とを有する。カバーケース１のカバー側板１−２は、ベースケース５のベース側板５−２に外側から取り付けられ、カバーケース１とベースケース５との間に回路基板３を収納する。また、カバー端板１−３は、カバー側板１−２がベース側板５−２に取り付けられた場合に端子台６を囲うような形状（図では略Ｌ字型）に形成される。
ベース用絶縁板４は、回路基板３とベースケース５との間に設けられ、回路基板３とベースケース５とを絶縁する。特に、ベース用絶縁板４は、短手方向の両側が折り曲げられ、ベースケース５のベース板５−１とベース側板５−２とに沿うように密着して設けられる。
カバー用絶縁板２は、回路基板３とカバーケース１との間に設けられ、回路基板３とカバーケース１とを絶縁する。特に、カバー用絶縁板２は、湾曲して形成され、回路基板３の部品実装面を覆うように設けられる。
なお、カバー用絶縁板２やベース用絶縁板４の厚さは、図では分かり易くするため厚く示すが、実際には無視できる程度である。 The discharge lamp lighting device 20 includes a cover case 1, a cover insulating plate 2, a circuit board 3, a base insulating plate 4, and a base case 5.
The circuit board 3 is formed in a rectangular shape, and a circuit component 7 for lighting the discharge lamp is mounted thereon. Further, the circuit board 3 is provided with an input terminal block 6a to which current is input from a commercial power source and an output terminal block 6b to output current to the discharge lamp. The input terminal block 6a and the output terminal block 6b are collectively referred to as the terminal block 6.
The base case 5 includes a base plate 5-1, and a base side plate 5-2 formed by bending both ends of the base plate 5-1 in the short direction. The circuit board 3 is attached to the base case 5. In particular, the circuit board 3 is attached to the base case 5 with the solder surface on the back side of the component mounting surface on which the circuit components 7 of the circuit board 3 are mounted facing the base case 5 side. Further, a gap 8 having a height H1 (see FIG. 3A) is provided between the base plate 5-1 of the base case 5 and the solder surface of the circuit board 3, and the circuit board 3 is provided in the base case 5. Is attached. For example, the base plate 5-1 or the base side plate 5-2 of the base case 5 is provided with a cut and raised, and the circuit board 3 is attached to the cut and raised so that a gap 8 is formed between the base plate 5-1 and the solder surface. Is freed up.
The cover case 1 includes a cover plate 1-1, a cover side plate 1-2 formed by bending both ends of the cover plate 1-1 in the short direction, and both ends of the cover plate 1-1 in the longitudinal direction. And a cover end plate 1-3 formed by being bent. The cover side plate 1-2 of the cover case 1 is attached to the base side plate 5-2 of the base case 5 from the outside, and houses the circuit board 3 between the cover case 1 and the base case 5. Further, the cover end plate 1-3 is formed in a shape (substantially L-shaped in the figure) that surrounds the terminal block 6 when the cover side plate 1-2 is attached to the base side plate 5-2.
The base insulating plate 4 is provided between the circuit board 3 and the base case 5 and insulates the circuit board 3 from the base case 5. In particular, the base insulating plate 4 is provided in close contact with the base plate 5-1 and the base side plate 5-2 of the base case 5 by bending both sides in the short direction.
The cover insulating plate 2 is provided between the circuit board 3 and the cover case 1 and insulates the circuit board 3 and the cover case 1. In particular, the cover insulating plate 2 is formed in a curved shape so as to cover the component mounting surface of the circuit board 3.
In addition, although the thickness of the insulating plate 2 for a cover and the insulating plate 4 for a base is shown thickly for easy understanding in a figure, it is a grade which can be disregarded actually.

この放電灯点灯装置２０では、図２と図３（ｄ）とに示すように、回路基板３の長手方向端部では、回路基板３のはんだ面とベース用絶縁板４との間の隙間８がカバーケース１の外部に露出している。そのため、この隙間８へ虫等が侵入してしまう虞がある。   In this discharge lamp lighting device 20, as shown in FIGS. 2 and 3 (d), a gap 8 between the solder surface of the circuit board 3 and the base insulating plate 4 is provided at the longitudinal end of the circuit board 3. Is exposed to the outside of the cover case 1. For this reason, there is a risk that insects or the like may enter the gap 8.

図４は、実施の形態１に係る放電灯点灯装置２０を示す図であり、図３と同様に（ａ）が左側面図、（ｂ）が平面図の一部、（ｃ）が正面図の一部、（ｄ）が長手方向の断面図の一部である。図５は、実施の形態１に係るベース用絶縁板４を示す斜視図である。
なお、実施の形態１に係る放電灯点灯装置２０について、図１から図３に示す放電灯点灯装置２０と異なる部分のみ説明する。 FIG. 4 is a diagram showing the discharge lamp lighting device 20 according to the first embodiment, in which (a) is a left side view, (b) is a part of a plan view, and (c) is a front view, as in FIG. (D) is a part of a longitudinal sectional view. FIG. 5 is a perspective view showing the base insulating plate 4 according to the first embodiment.
In addition, regarding the discharge lamp lighting device 20 according to the first embodiment, only portions different from the discharge lamp lighting device 20 shown in FIGS. 1 to 3 will be described.

図４，５に示すように、ベース用絶縁板４には、長手方向端部付近で回路基板３側へ折り曲げられた絶縁板立ち上げ部４−１が設けられる。
絶縁板立ち上げ部４−１は、ベース用絶縁板４が取り付けられたベースケース５に回路基板３が取り付けられた場合に、回路基板３の長手方向端部を覆う。つまり、絶縁板立ち上げ部４−１は、ベース用絶縁板４が取り付けられたベースケース５に回路基板３が取り付けられた場合に、回路基板３の長手方向端部に接するように設けられる。
絶縁板立ち上げ部４−１により、回路基板３の長手方向端部において、回路基板３のはんだ面とベースケース５のベース板５−１との間の隙間８が塞がれる。したがって、隙間８へ虫等が侵入することを防ぐことができる。 As shown in FIGS. 4 and 5, the base insulating plate 4 is provided with an insulating plate rising portion 4-1 bent toward the circuit board 3 near the end in the longitudinal direction.
When the circuit board 3 is attached to the base case 5 to which the base insulating plate 4 is attached, the insulating plate rising part 4-1 covers the longitudinal direction end of the circuit board 3. That is, when the circuit board 3 is attached to the base case 5 to which the base insulating plate 4 is attached, the insulating plate rising part 4-1 is provided so as to contact the longitudinal end of the circuit board 3.
The gap 8 between the solder surface of the circuit board 3 and the base plate 5-1 of the base case 5 is closed at the longitudinal end of the circuit board 3 by the insulating plate rising part 4-1. Therefore, insects and the like can be prevented from entering the gap 8.

また、ベースケース５には、長手方向端部付近に切り起こし５−３が設けられる。切り起こし５−３は、ベースケース５に回路基板３が取り付けられた場合に、回路基板３の長手方向端部が位置する部分に設けられる。
そのため、長手方向端部付近が折り返されたベース用絶縁板４をベースケース５に取り付ける場合に、絶縁板立ち上げ部４−１が切り起こし５−３に当たるように取り付けることで、回路基板３のはんだ面とベースケース５のベース板５−１との間の隙間８を塞ぐことができる。つまり、切り起こし５−３は、ベース用絶縁板４の設置位置の位置決めに利用される。 The base case 5 is provided with a cut-up 5-3 near the end in the longitudinal direction. When the circuit board 3 is attached to the base case 5, the cut and raised 5-3 is provided at a portion where the longitudinal end of the circuit board 3 is located.
Therefore, when the base insulating plate 4 whose end portion in the longitudinal direction is folded back is attached to the base case 5, the insulating plate rising portion 4-1 is cut and raised so as to hit 5-3, so that the circuit board 3 The gap 8 between the solder surface and the base plate 5-1 of the base case 5 can be closed. That is, the cut and raised 5-3 is used for positioning the installation position of the base insulating plate 4.

なお、本実施の形態では、放電灯を用いる場合について説明したが、放電灯に代え、白色電球やＬＥＤ等のランプであってもよい。
また、本実施の形態にかかる点灯装置（放電灯点灯装置２００）と器具本体とを備える照明器具であれば、器具本体内に虫等が侵入しても、点灯装置内に進入することを防止できる。 In the present embodiment, the case where a discharge lamp is used has been described. However, a lamp such as a white light bulb or an LED may be used instead of the discharge lamp.
Moreover, if it is a lighting fixture provided with the lighting device (discharge lamp lighting device 200) and fixture main body concerning this Embodiment, even if an insect etc. penetrate | invade into a fixture main body, it will prevent entering into a lighting device. it can.

実施の形態２．
実施の形態２では、実施の形態１と同様に、回路基板３のはんだ面側と、ベースケース５との間に虫等が侵入することを防止する構成について説明する。
なお、実施の形態２に係る放電灯点灯装置２０について、図１から図３に示す放電灯点灯装置２０と異なる部分のみ説明する。 Embodiment 2. FIG.
In the second embodiment, as in the first embodiment, a configuration for preventing insects and the like from entering between the solder surface side of the circuit board 3 and the base case 5 will be described.
In addition, about the discharge lamp lighting device 20 which concerns on Embodiment 2, only a different part from the discharge lamp lighting device 20 shown in FIGS. 1-3 is demonstrated.

図６は、実施の形態２に係る放電灯点灯装置２０を示す図であり、図３と同様に（ａ）が左側面図、（ｂ）が平面図の一部、（ｃ）が正面図の一部、（ｄ）が長手方向の断面図の一部である。図７は、実施の形態２に係る回路基板３を示す斜視図である。   FIG. 6 is a diagram showing a discharge lamp lighting device 20 according to the second embodiment, in which (a) is a left side view, (b) is a part of a plan view, and (c) is a front view, as in FIG. (D) is a part of a longitudinal sectional view. FIG. 7 is a perspective view showing the circuit board 3 according to the second embodiment.

図６，７に示すように、回路基板３のはんだ面の長手方向端部付近には、面実装部品３−１（所定の回路部品）が設けられる。
面実装部品３−１の高さＨ２は、隙間８の高さＨ１（図３（ａ）参照）と略同一である。また、回路基板３の短手方向の面実装部品３−１の幅Ｗ２は、回路基板３の短手方向の幅Ｗ１（図３（ａ）参照）と略同一である。
したがって、ベースケース５に回路基板３を取り付けた場合に、回路基板３の長手方向端部付近で面実装部品３−１により隙間８が塞がれる。
なお、面実装部品３−１は、略矩形状である。そのため、ベース用絶縁板４が取り付けられたベースケース５に、回路基板３を取り付けた場合に、面実装部品３−１はベース用絶縁板４と面で接する。したがって、確実に虫等の侵入を防ぐことができる。 As shown in FIGS. 6 and 7, a surface mounting component 3-1 (predetermined circuit component) is provided in the vicinity of the end in the longitudinal direction of the solder surface of the circuit board 3.
The height H2 of the surface mount component 3-1 is substantially the same as the height H1 of the gap 8 (see FIG. 3A). Further, the width W2 of the surface mounting component 3-1 in the short direction of the circuit board 3 is substantially the same as the width W1 of the circuit board 3 in the short direction (see FIG. 3A).
Therefore, when the circuit board 3 is attached to the base case 5, the gap 8 is closed by the surface mounting component 3-1 in the vicinity of the end in the longitudinal direction of the circuit board 3.
The surface mounting component 3-1 has a substantially rectangular shape. Therefore, when the circuit board 3 is attached to the base case 5 to which the base insulating plate 4 is attached, the surface mount component 3-1 contacts the base insulating plate 4 on the surface. Therefore, it is possible to reliably prevent insects and the like from entering.

図８は、図６，７とは異なる実施の形態２に係る放電灯点灯装置２０を示す図であり、図３と同様に（ａ）が左側面図、（ｂ）が平面図の一部、（ｃ）が正面図の一部、（ｄ）が長手方向の断面図の一部である。   8A and 8B are diagrams showing a discharge lamp lighting device 20 according to Embodiment 2 different from FIGS. 6 and 7, in which FIG. 8A is a left side view and FIG. (C) is a part of the front view, and (d) is a part of the cross-sectional view in the longitudinal direction.

図８に示す放電灯点灯装置２０では、回路基板３に面実装部品３−１を設けることに代え、回路基板３の長手方向端部付近の回路基板３とベース用絶縁板４との間に、パッキン等の害虫防除部材９が設けられる。害虫防除部材９の高さＨ３は隙間８の高さＨ１（図３（ａ）参照）と略同一であり、害虫防除部材９の幅Ｗ３は回路基板３の短手方向の幅Ｗ１（図３（ａ）参照）と略同一である。
したがって、ベースケース５に回路基板３を取り付けた場合に、害虫防除部材９により隙間８が塞がれる。
なお、害虫防除部材９は、略台形状である。そのため、ベース用絶縁板４が取り付けられたベースケース５に、回路基板３を取り付けた場合に、害虫防除部材９は回路基板３及びベース用絶縁板４と面で接する。したがって、確実に虫等の侵入を防ぐことができる。 In the discharge lamp lighting device 20 shown in FIG. 8, instead of providing the surface mounting component 3-1 on the circuit board 3, the circuit board 3 near the end in the longitudinal direction of the circuit board 3 and the base insulating plate 4 are disposed. A pest control member 9 such as packing is provided. The height H3 of the pest control member 9 is substantially the same as the height H1 of the gap 8 (see FIG. 3A), and the width W3 of the pest control member 9 is the width W1 in the short direction of the circuit board 3 (FIG. 3). (See (a)).
Therefore, when the circuit board 3 is attached to the base case 5, the gap 8 is closed by the pest control member 9.
The pest control member 9 has a substantially trapezoidal shape. Therefore, when the circuit board 3 is attached to the base case 5 to which the base insulating plate 4 is attached, the pest control member 9 contacts the circuit board 3 and the base insulating plate 4 on the surface. Therefore, it is possible to reliably prevent insects and the like from entering.

なお、図では、ベース用絶縁板４の厚さ分隙間８が残っているように見えるが、上述したように、ベース用絶縁板４の厚さは無視できる程度であるため影響は無い。   In the drawing, it seems that the gap 8 remains as much as the thickness of the base insulating plate 4, but as described above, the thickness of the base insulating plate 4 is negligible, so there is no influence.

実施の形態３．
実施の形態３では、実施の形態１，２と同様に、回路基板３のはんだ面側と、ベースケース５との間に虫等が侵入することを防止する構成について説明する。
なお、実施の形態３に係る放電灯点灯装置２０について、図１から図３に示す放電灯点灯装置２０と異なる部分のみ説明する。 Embodiment 3 FIG.
In the third embodiment, as in the first and second embodiments, a configuration for preventing insects and the like from entering between the solder surface side of the circuit board 3 and the base case 5 will be described.
Note that only the portion of the discharge lamp lighting device 20 according to Embodiment 3 that is different from the discharge lamp lighting device 20 shown in FIGS. 1 to 3 will be described.

図９は、実施の形態３に係る放電灯点灯装置２０を示す図であり、図３と同様に（ａ）が左側面図、（ｂ）が平面図の一部、（ｃ）が正面図の一部、（ｄ）が長手方向の断面図の一部である。図１０は、実施の形態３に係るベースケース５を示す斜視図である。   FIG. 9 is a diagram showing a discharge lamp lighting device 20 according to Embodiment 3, in which (a) is a left side view, (b) is a part of a plan view, and (c) is a front view, as in FIG. (D) is a part of a longitudinal sectional view. FIG. 10 is a perspective view showing the base case 5 according to the third embodiment.

図９，１０に示すように、ベースケース５の長手方向端部付近には、回路基板３側へ突出した凸部５−４が設けられる。凸部５−４の高さＨ４は隙間８の高さＨ１（図３（ａ）参照）と略同一である。したがって、ベースケース５に回路基板３を取り付けた場合に、凸部５−４により隙間８が塞がれる。
なお、凸部５−４は、略台形状であり、回路基板３とベース用絶縁板４を介して面で接する。そのため、確実に虫等の侵入を防ぐことができる。 As shown in FIGS. 9 and 10, a convex portion 5-4 that protrudes toward the circuit board 3 side is provided in the vicinity of the end portion in the longitudinal direction of the base case 5. The height H4 of the convex portion 5-4 is substantially the same as the height H1 of the gap 8 (see FIG. 3A). Therefore, when the circuit board 3 is attached to the base case 5, the gap 8 is closed by the convex portion 5-4.
The convex portion 5-4 has a substantially trapezoidal shape, and comes into contact with the circuit board 3 through the base insulating plate 4 on the surface. Therefore, invasion of insects and the like can be surely prevented.

また、ベース用絶縁板４にも、ベースケース５の凸部５−４の形状とほぼ同じ凸部を備えてもよいし、ベースケース５に凸部５−４を設けず、ベース用絶縁板４のみに凸部５−４の形状とほぼ同じ凸部を備えてもよい。   Further, the base insulating plate 4 may be provided with a convex portion substantially the same as the shape of the convex portion 5-4 of the base case 5, or the base case 5 is not provided with the convex portion 5-4, but the base insulating plate. Only 4 may be provided with a convex portion substantially the same as the shape of the convex portion 5-4.

実施の形態４．
以上の実施の形態では、回路基板３のはんだ面側と、ベースケース５との間に虫等が侵入することを防止する構成について説明した。実施の形態４では、回路基板３の部品実装面とカバーケース１との間に虫等が侵入することを防止する構成について説明する。
なお、実施の形態４に係る放電灯点灯装置２０について、図１から図３に示す放電灯点灯装置２０と異なる部分のみ説明する。 Embodiment 4 FIG.
In the above embodiment, the structure which prevents an insect etc. invading between the solder surface side of the circuit board 3 and the base case 5 was demonstrated. In the fourth embodiment, a configuration for preventing insects and the like from entering between the component mounting surface of the circuit board 3 and the cover case 1 will be described.
Note that only a portion of the discharge lamp lighting device 20 according to Embodiment 4 that is different from the discharge lamp lighting device 20 shown in FIGS. 1 to 3 will be described.

図１から図３に示す構成では、カバーケース１のカバー端板１−３は、端子台６部分を囲むように略Ｌ字型に形成され、カバーケース１と端子台６との間に隙間を空けないようにすることで、回路基板３の部品実装面とカバーケース１との間に虫等が侵入することを防止した。しかし、この構成では、カバーケース１の加工が複雑になる。   In the configuration shown in FIGS. 1 to 3, the cover end plate 1-3 of the cover case 1 is formed in an approximately L shape so as to surround the terminal block 6, and a gap is formed between the cover case 1 and the terminal block 6. By preventing the gap from being formed, insects and the like are prevented from entering between the component mounting surface of the circuit board 3 and the cover case 1. However, in this configuration, processing of the cover case 1 is complicated.

図１１は、実施の形態４に係る放電灯点灯装置２０を示す図であり、図３と同様に（ａ）が左側面図、（ｂ）が平面図の一部、（ｃ）が正面図の一部、（ｄ）が断面図の一部である。   FIG. 11 is a diagram showing a discharge lamp lighting device 20 according to Embodiment 4, in which (a) is a left side view, (b) is a part of a plan view, and (c) is a front view, as in FIG. (D) is a part of a sectional view.

図１１に示すように、端子台６の幅Ｗ４を回路基板３の短手方向の幅Ｗ１（図３（ａ）参照）と略同一の幅にする。また、端子台６のカバーケース１側を平面にする。これにより、カバーケース１の長手方向端部を単に回路基板３側へ折り曲げる加工をすれば、カバーケース１と端子台６との間の隙間を塞ぐことができる。したがって、カバーケース１を複雑な形状に加工する必要はない。   As shown in FIG. 11, the width W4 of the terminal block 6 is made substantially the same as the width W1 of the circuit board 3 in the short direction (see FIG. 3A). Further, the cover case 1 side of the terminal block 6 is made flat. Thereby, if the process which just bend | folds the longitudinal direction edge part of the cover case 1 to the circuit board 3 side is performed, the clearance gap between the cover case 1 and the terminal block 6 can be plugged up. Therefore, it is not necessary to process the cover case 1 into a complicated shape.

実施の形態５．
実施の形態５では、実施の形態４と同様に、回路基板３の部品実装面とカバーケース１との間に虫等が侵入することを防止する構成について説明する。
なお、実施の形態５に係る放電灯点灯装置２０について、図１から図３に示す放電灯点灯装置２０と異なる部分のみ説明する。 Embodiment 5 FIG.
In the fifth embodiment, as in the fourth embodiment, a configuration for preventing insects and the like from entering between the component mounting surface of the circuit board 3 and the cover case 1 will be described.
Note that only a portion of the discharge lamp lighting device 20 according to Embodiment 5 that is different from the discharge lamp lighting device 20 shown in FIGS. 1 to 3 will be described.

図１２は、実施の形態５に係る放電灯点灯装置２０を示す図であり、図３と同様に（ａ）が左側面図、（ｂ）が平面図の一部、（ｃ）が正面図の一部、（ｄ）が断面図の一部である。図１３は、実施の形態５に係るカバー用絶縁板２の斜視図である。   12A and 12B are diagrams showing a discharge lamp lighting device 20 according to the fifth embodiment. FIG. 12A is a left side view, FIG. 12B is a part of a plan view, and FIG. (D) is a part of a sectional view. FIG. 13 is a perspective view of the insulating cover plate 2 according to the fifth embodiment.

図１２，１３に示すように、カバー用絶縁板２は、短手方向の幅が回路基板３の短手方向の幅と略同一の矩形状に形成され、カバー用絶縁板２の長手方向端部付近には、回路基板３側へ折り曲げられた絶縁板立ち下げ部２−１が設けられる。
カバー用絶縁板２は、カバーケース１のカバー板１−１に密着するように設けられる。また、カバー用絶縁板２は、絶縁板立ち下げ部２−１が端子台６の背面部側（回路部品が実装される側）になるように設けられる（図１２（ｄ）参照）。また、絶縁板立ち下げ部２−１の高さＨ５は、カバー板１−１と回路基板３の部品実装面との間の距離Ｌ１と略同一である。つまり、絶縁板立ち下げ部２−１の端部は、回路基板３の部品実装面と接触する。
したがって、端子台６の背面部側で、回路基板３の部品実装面とカバーケース１との間の隙間は、絶縁板立ち下げ部２−１によって塞がれる。 As shown in FIGS. 12 and 13, the cover insulating plate 2 is formed in a rectangular shape whose width in the short direction is substantially the same as the width in the short direction of the circuit board 3. An insulating plate falling part 2-1 that is bent toward the circuit board 3 is provided in the vicinity of the part.
The cover insulating plate 2 is provided in close contact with the cover plate 1-1 of the cover case 1. The insulating plate 2 for the cover is provided so that the insulating plate falling portion 2-1 is on the back side of the terminal block 6 (the side on which circuit components are mounted) (see FIG. 12D). The height H5 of the insulating plate falling part 2-1 is substantially the same as the distance L1 between the cover plate 1-1 and the component mounting surface of the circuit board 3. That is, the end of the insulating plate falling part 2-1 is in contact with the component mounting surface of the circuit board 3.
Therefore, the gap between the component mounting surface of the circuit board 3 and the cover case 1 on the back side of the terminal block 6 is closed by the insulating plate falling part 2-1.

図１４は、図１２とは異なる実施の形態５に係る放電灯点灯装置２０を示す図であり、図３と同様に（ａ）が左側面図、（ｂ）が平面図の一部、（ｃ）が正面図の一部、（ｄ）が断面図の一部である。   14 is a view showing a discharge lamp lighting device 20 according to Embodiment 5 different from FIG. 12, in which (a) is a left side view, (b) is a part of a plan view, like FIG. c) is a part of the front view, and (d) is a part of the sectional view.

図１４に示すように、絶縁板立ち下げ部２−１を設けることに代え、カバー用絶縁板２と回路基板３の部品実装面との間に、パッキン等の害虫防除部材１０を設けた。
害虫防除部材１０は、害虫防除部材１０は、端子台６の背面部側にカバー用絶縁板２と回路基板３の部品実装面とに接触するように設けられる（図１３（ｄ）参照）。また、害虫防除部材１０の高さＨ６は、カバー板１−１と回路基板３の部品実装面との間の距離Ｌ１と略同一である。
したがって、端子台６の背面部側で、回路基板３の部品実装面とカバーケース１との間の隙間は、害虫防除部材１０によって塞がれる。 As shown in FIG. 14, a pest control member 10 such as packing was provided between the cover insulating plate 2 and the component mounting surface of the circuit board 3 instead of providing the insulating plate falling part 2-1.
The pest control member 10 is provided on the back side of the terminal block 6 so as to be in contact with the cover insulating plate 2 and the component mounting surface of the circuit board 3 (see FIG. 13D). The height H6 of the pest control member 10 is substantially the same as the distance L1 between the cover plate 1-1 and the component mounting surface of the circuit board 3.
Therefore, the gap between the component mounting surface of the circuit board 3 and the cover case 1 on the back side of the terminal block 6 is closed by the pest control member 10.

図１５は、図１２に示す絶縁板立ち下げ部２−１と回路基板３の部品実装面との接触部分の説明図である。
図１５（ａ）に示すように、回路基板３の部品実装面に溝を設け、絶縁板立ち下げ部２−１の端部をその溝へ挿入するようにしてもよい。回路基板３の部品実装面に設ける溝を断面形状がＶ字型の溝としてもよい。
また、図１５（ｂ）に示すように、回路基板３の部品実装面に凹部（あるいは孔）を設けるとともに、絶縁板立ち下げ部２−１の端部に凸部を設け、凸部を凹部に挿入するようにしてもよい。
このような構造とすることで、絶縁板立ち下げ部２−１と回路基板３の部品実装面との間に隙間ができづらくなる。 FIG. 15 is an explanatory diagram of a contact portion between the insulating plate falling part 2-1 and the component mounting surface of the circuit board 3 shown in FIG.
As shown in FIG. 15A, a groove may be provided on the component mounting surface of the circuit board 3, and the end of the insulating plate falling part 2-1 may be inserted into the groove. The groove provided on the component mounting surface of the circuit board 3 may be a V-shaped groove.
Further, as shown in FIG. 15B, a recess (or a hole) is provided on the component mounting surface of the circuit board 3, a protrusion is provided at the end of the insulating plate falling part 2-1, and the protrusion is a recess. You may make it insert in.
With such a structure, it is difficult to form a gap between the insulating plate falling part 2-1 and the component mounting surface of the circuit board 3.

なお、害虫防除部材１０を用いる場合についても同様に、回路基板３の部品実装面に溝を設け、害虫防除部材１０の端部をその溝へ挿入するようにしてもよいし、回路基板３の部品実装面に凹部を設けるとともに、害虫防除部材１０の端部に凸部を設け、凸部を凹部に挿入するようにしてもよい。   Similarly, when the pest control member 10 is used, a groove may be provided on the component mounting surface of the circuit board 3 and the end of the pest control member 10 may be inserted into the groove. While providing a recessed part in a component mounting surface, you may make it provide a convex part in the edge part of the pest control member 10, and insert a convex part in a recessed part.
