Connect the wiring between the lighting devices 2. FIG. 2 is a three-view view of the plane, front, and side of the lighting device. FIG. 3 shows a partially disassembled view of the external power supply connection side of the lighting device 1, and FIG. 4 shows a partially disassembled view of the LED light source lamp 1 connection side. FIG. 5 shows a single item diagram of the rubber packing 6 for sealing housed in the lighting device 2.

照明装置１００は、電源BOX4と、点灯用回路基板3と、を有し、前記点灯用回路基板3は、電源BOX4の内部に有し、前記電源BOX4の両端の開口部には、シール用ゴムパッキン6を有し、前記シール用ゴムパッキン6の外側には、覆うように樹脂カバー5を有している。シール用ゴムパッキン6には、点灯用回路基板3と合わさる位置に溝形状と溝形状側面に複数のリブ形状を有しており、点灯用回路基板3を押えることが出来る。また、前記シール用ゴムパッキン6の輪郭は、電源BOX4の開口面に沿う平面形状となっており、押し合わせることで、水密性を保持することが出来る。また、前記シール用ゴムパッキン6には、樹脂カバー5と合わせる面に、三角のリブ形状を外周に有しており、押し合わせることで、水密性を保持することを特徴とする。電源ＢＯＸ４と樹脂カバー５との間に両者の水密のために位置するシール用ゴムパッキン６を有する。 The lighting device 100 has a power supply box 4 and a lighting circuit board 3, the lighting circuit board 3 is inside the power supply box 4, and rubber for sealing is provided in the openings at both ends of the power supply box 4. It has a packing 6, and a resin cover 5 is provided on the outside of the sealing rubber packing 6 so as to cover the packing 6. The rubber packing 6 for sealing has a groove shape at a position where it meets the lighting circuit board 3 and a plurality of rib shapes on the side surface of the groove shape, so that the lighting circuit board 3 can be pressed. Further, the contour of the rubber packing 6 for sealing has a planar shape along the opening surface of the power supply box 4, and the watertightness can be maintained by pressing them together. Further, the rubber packing 6 for sealing has a triangular rib shape on the outer circumference on the surface to be combined with the resin cover 5, and is characterized in that watertightness is maintained by pressing the rubber packing 6. A sealing rubber packing 6 is provided between the power supply BOX 4 and the resin cover 5 for watertightness of both.

図３、図４に示すように、点灯装置２は、点灯用回路基板３と、電源ＢＯＸ４と、固定金具４ａと、絶縁用の樹脂シート4bと、樹脂カバー５と、シール用ゴムパッキン６と、LED光源接続用口出線７と、外部電源接続用口出線8と、ゴムブッシュ９と、ゴムブッシュ押え金具１０と、を有する。点灯装置2の筐体は、口の字形状のアルミ押出しで形成された電源BOX4である。電源ＢＯＸ４は、略角柱形状をしており、両端に開口部を有する。電源BOX4の中に収容する、点灯用回路基板3は、高温となることから、筐体となる電源BOX4は放熱性の良い材料で形成することが望ましい。また。電源BOX4の下面には、天井に取付けるための固定金具4aがあり、重量を支え、また放熱性の良い材料とすることが望ましい。また、電源用BOX4の重量により、固定金具4aが破損することが無いように、軽い材料のアルミを使用することが望ましい。 As shown in FIGS. 3 and 4, the lighting device 2 includes a lighting circuit board 3, a power supply BOX 4, a fixing bracket 4a, a resin sheet 4b for insulation, a resin cover 5, and a rubber packing 6 for sealing. It has an LED light source connecting outlet wire 7, an external power supply connecting outlet wire 8, a rubber bush 9, and a rubber bush holding metal fitting 10. The housing of the lighting device 2 is a power supply box 4 formed of a mouth-shaped aluminum extrusion. The power supply BOX 4 has a substantially prismatic shape and has openings at both ends. Since the lighting circuit board 3 housed in the power supply box 4 has a high temperature, it is desirable that the power supply box 4 as a housing is made of a material having good heat dissipation. Also. On the lower surface of the power supply box 4, there is a fixing bracket 4a for mounting on the ceiling, and it is desirable to use a material that supports the weight and has good heat dissipation. In addition, it is desirable to use aluminum, which is a light material, so that the fixing bracket 4a is not damaged by the weight of the power supply box 4.

図３、４に示すように、点灯用回路基板3の両端には、配線接続用のコネクタがあり、外部電源接続用口出線8と、LED光源接続用口出線7が接続される。 As shown in FIGS. 3 and 4, there are connectors for wiring connection at both ends of the lighting circuit board 3, and the outlet wire 8 for connecting an external power supply and the outlet wire 7 for connecting an LED light source are connected.

樹脂カバー５は、略四角形状の部材である。樹脂カバー５は、シール用ゴムパッキン６を介して電源ＢＯＸ４の開口部を塞ぐように設けられる。樹脂カバー５は、樹脂カバー開口部を備える。樹脂カバー開口部には、口出線が通過する配線通し穴を備えたゴムブッシュ９が配置される。樹脂カバー開口部にゴムブッシュ９が配置されることで、口出線が通過する際のシールとなる効果を奏する。また、ゴムブッシュ9を、樹脂カバー5に固定するため、ゴムブッシュ押え金具10をゴムブッシュ９に被せ、ねじにより樹脂カバー５に固定する。ゴムブッシュ押え金具10を用いることにより、口出線の固定保持力を増すことが出来、万が一に点灯装置2の固定金具4aが破損した場合でも、口出線の保持により、直接の落下に至らないよう補助することができる。そのため、ゴムブッシュ9と、シール用ゴムパッキン6は別部材として、別々に設けることが望ましい。 The resin cover 5 is a substantially square member. The resin cover 5 is provided so as to close the opening of the power supply BOX 4 via the sealing rubber packing 6. The resin cover 5 includes a resin cover opening. A rubber bush 9 having a wiring through hole through which the lead wire passes is arranged in the resin cover opening. By arranging the rubber bush 9 in the opening of the resin cover, it has the effect of serving as a seal when the lead wire passes through. Further, in order to fix the rubber bush 9 to the resin cover 5, the rubber bush holding metal fitting 10 is put on the rubber bush 9 and fixed to the resin cover 5 with screws. By using the rubber bush holding metal fitting 10, the fixing holding force of the lead wire can be increased, and even if the fixing metal fitting 4a of the lighting device 2 is damaged, the holding of the lead wire leads to a direct drop. Can help you not. Therefore, it is desirable that the rubber bush 9 and the rubber packing 6 for sealing are separately provided as separate members.

図５に示すシール用ゴムパッキン6は、工場環境での粉塵や、雨漏りにより水滴が、点灯装置2の外側を伝わる異常状態時にも、点灯装置２の内部への侵入を防止するためのものである。また、点灯装置２が振動の大きい環境に設置される場合もあるため、シール用ゴムパッキン6は、密着性の良い柔らかい材料とすることが望ましい。 The rubber packing 6 for sealing shown in FIG. 5 is for preventing water droplets from entering the inside of the lighting device 2 even in an abnormal state where dust or water droplets are transmitted to the outside of the lighting device 2 due to rain leakage in a factory environment. is there. Further, since the lighting device 2 may be installed in an environment with large vibration, it is desirable that the rubber packing 6 for sealing is made of a soft material having good adhesion.

本実施例における最も温度の高いものは、点灯用回路基板3である。点灯用回路基板3の熱は、電源BOX4により放熱させるが、電源BOX4に直接接するシール用ゴムパッキン6の材料は、高温環境に耐える材料とすることが望ましい。また、点灯用回路基板3におけるコンデンサーが万が一ショートし、火花が出る異常な事態に、延焼が筐体内で終息する様に、シール用ゴムパッキン6や、両端外郭の樹脂カバー5は熱に強い材料とすることが望ましい。 The one having the highest temperature in this embodiment is the lighting circuit board 3. The heat of the lighting circuit board 3 is dissipated by the power supply box 4, but the material of the sealing rubber packing 6 that is in direct contact with the power supply box 4 is preferably a material that can withstand a high temperature environment. In addition, the rubber packing 6 for sealing and the resin cover 5 on both ends are heat-resistant materials so that the spread of fire ends inside the housing in the unlikely event that the capacitor in the lighting circuit board 3 is short-circuited and sparks occur. Is desirable.

点灯用回路基板3には、放熱用の放熱板が配置されている。放熱用の板にはねじ固定用の穴が設けられており、電源BOX4の外側側面より、ねじ固定をする。 A heat radiating plate for heat dissipation is arranged on the lighting circuit board 3. The heat dissipation plate is provided with holes for fixing screws, and screws are fixed from the outer side surface of the power supply box 4.

放熱板が接する面以外は、点灯用回路基板3と電源BOX4との間に、絶縁用の樹脂シート4bがある。樹脂シート４ｂは、電源BOX4の口の字形状に沿って折り曲げたものである。そのため、ねじ固定と併用し、点灯用回路基板3を固定する方法として、シール用ゴムパッキン6に、基板を固定するための溝形状を設けている。点灯用回路基板3を固定するために剛性をあげると外部から衝撃が直接半導体に伝わってしまうことから、側面部の固定にシール用ゴムパッキン6で行うことにより、衝撃を緩和することが出来る。 There is a resin sheet 4b for insulation between the lighting circuit board 3 and the power supply box 4 except for the surface where the heat radiating plate is in contact. The resin sheet 4b is bent along the shape of the mouth of the power supply box 4. Therefore, as a method of fixing the lighting circuit board 3 in combination with screw fixing, the sealing rubber packing 6 is provided with a groove shape for fixing the board. If the rigidity is increased to fix the lighting circuit board 3, the impact is directly transmitted to the semiconductor from the outside. Therefore, the impact can be mitigated by fixing the side surface portion with the rubber packing 6 for sealing.

図５のシール用ゴムパッキン6には、電源ＢＯＸ４の端面に接するシール接地面部6ａと、拡大図に示すようにシール接地面部から前記樹脂カバー方向に突出する環状の三角リブ６ｂが設けられている。三角リブ６ｂは、略三角形上のリブが、樹脂カバー5に接する側の外周に環状になるよう設けられている。三角リブ６ｂを線で潰すことにより（三角リブの頂点を樹脂カバーの面で潰すことにより）、樹脂カバー5側の水密性を確保することが出来る。電源ＢＯＸ４と、シール用ゴムパッキン６と、樹脂カバー５と、を組み合わせた状態で、環状の三角リブは、樹脂カバー５に接触する。 The rubber packing 6 for sealing in FIG. 5 is provided with a seal grounding surface portion 6a in contact with the end surface of the power supply BOX 4 and an annular triangular rib 6b protruding from the sealing grounding surface portion in the resin cover direction as shown in the enlarged view. .. The triangular rib 6b is provided so that the rib on the substantially triangular shape forms an annular shape on the outer circumference on the side in contact with the resin cover 5. By crushing the triangular rib 6b with a line (by crushing the apex of the triangular rib with the surface of the resin cover), the watertightness of the resin cover 5 side can be ensured. In a state where the power supply BOX 4, the rubber packing 6 for sealing, and the resin cover 5 are combined, the annular triangular rib comes into contact with the resin cover 5.

図５のように、シール用ゴムパッキン6はブロック形状を有している。ブロック形状のため、従来使用されていたようなOリング等を溝に沿って這わせる作業がなく、シール用ゴムパッキン６を電源BOX1-1bの開口部へ置くだけで水密性を確保することができるという簡略化および作業工程を低減するという効果を奏することが出来る。 As shown in FIG. 5, the sealing rubber packing 6 has a block shape. Due to the block shape, there is no need to crawl the O-ring etc. along the groove as was used in the past, and watertightness can be ensured simply by placing the sealing rubber packing 6 in the opening of the power supply box 1-1b. It is possible to achieve the effect of simplifying the work process and reducing the work process.
