FIG. 3A is a perspective view of a state in which the fixing bracket is viewed obliquely from above, and FIG. 3B is a perspective view of the state in which the fixing bracket is viewed from diagonally below.
As shown in FIGS. 3A and 3B, the substantially square fixing bracket 3 is made of an elastic metal, and the outer clearance of the lighting device main body 2 is formed on both sides of one end of the fixing bracket 3. Claw portions 3 a that hang down so as to fit into the mounting bracket 3, corner portions 3 b that protrude so as to come into contact with the upper surface of the lighting device main body 2, are provided on both sides of the other end portion of the fixing bracket 3. A bent portion 3c bent in the shape of "" is provided. The bending width of the bent portion 3 c is slightly larger than the gap between the lighting device main body 2 and the opening 4 a of the water-proof case 4.

次に、本発明の実施の形態1の防浸型点灯装置の組み立て工程について図4〜図7に基づいて説明する。
まず、図6に示すように、点灯装置本体2のケース上蓋2aの長手方向の一方の端部両側の隙間2a1に、固定金具3の爪部3aを挿入し、固定金具3の角部3bがケース上蓋2aの上面に接触するように、固定金具3を点灯装置本体2の一方の端部に取り付ける。
次に、一方の端部に固定金具3を取り付けた点灯装置本体2の他方の端部を、防浸ケース4の開口部4aから挿入していく。
そして、点灯装置本体2を防浸ケース4内に挿入していくと、固定金具3の曲げ部3cが防浸ケース4の開口部4aの内周面に接触する。
Next, the assembly process of the immersion type lighting device according to the first embodiment of the present invention will be described with reference to FIGS.
First, as shown in FIG. 6, the claw portion 3a of the fixing bracket 3 is inserted into the gap 2a1 on both sides of one end in the longitudinal direction of the case upper lid 2a of the lighting device body 2, and the corner portion 3b of the fixing bracket 3 is The fixture 3 is attached to one end of the lighting device main body 2 so as to contact the upper surface of the case upper lid 2a.
Next, the other end portion of the lighting device main body 2 having the fixing bracket 3 attached to one end portion is inserted from the opening 4 a of the water-proof case 4.
When the lighting device main body 2 is inserted into the water-proof case 4, the bent portion 3 c of the fixing bracket 3 comes into contact with the inner peripheral surface of the opening 4 a of the water-proof case 4.

このとき、防浸ケース4の開口部4aの内周面と点灯装置本体2の上面との隙間の距離Xと、点灯装置本体2の上面と曲げ部3cの頂点までの距離Yとの関係は、X<Yとなっている。
そこで、点灯装置本体2をさらに防浸ケース4内に挿入すると、固定金具3の弾性力によって、点灯装置本体2の底面が防浸ケース4の内周面に接触する。
こうして、点灯装置本体2を防湿ケース4に収納後は、防浸ケース4の両端にそれぞれパッキン5を防浸ケース4の開口部4aに挿嵌し、そのパッキン5のリード線挿通部5aが取付金具6の挿通部挿入穴6aに挿入されるようにパッキン5に対して取付金具6を取り付け、ネジ7を取付金具6の取付孔6bに挿入し、防浸ケース4の両側に設けられている半割ネジ部4bにネジ込み、その取付金具6によりパッキン5を防浸ケース4の端部に固定する。
At this time, the relationship between the distance X between the inner peripheral surface of the opening 4a of the immersion prevention case 4 and the upper surface of the lighting device body 2 and the distance Y between the upper surface of the lighting device body 2 and the apex of the bent portion 3c is , X <Y.
Therefore, when the lighting device body 2 is further inserted into the water-proof case 4, the bottom surface of the lighting device body 2 comes into contact with the inner peripheral surface of the water-proof case 4 by the elastic force of the fixing bracket 3.
Thus, after the lighting device main body 2 is stored in the moisture-proof case 4, the packings 5 are inserted into the openings 4a of the waterproof case 4 at both ends of the waterproof case 4, and the lead wire insertion portions 5a of the packing 5 are attached. The mounting bracket 6 is attached to the packing 5 so as to be inserted into the insertion portion insertion hole 6 a of the bracket 6, and the screws 7 are inserted into the mounting holes 6 b of the mounting bracket 6, and are provided on both sides of the water-proof case 4. The half screw portion 4 b is screwed, and the packing 5 is fixed to the end portion of the anti-soaking case 4 by the mounting bracket 6.

このように、曲げ部3cを有する固定金具3を点灯装置本体2の上面に装着し、固定金具3を装着した点灯装置本体2を防浸ケース4に挿着すればよいので、防浸ケース4に対して点灯装置本体2の組立作業性がよく、防浸ケース4内への点灯装置本体2の挿着後は固定金具3の弾性により曲げ部3cが拡がり、点灯装置本体2と防浸ケース4が固定金具3によって押し付けられた状態で密着するため、放熱効果を向上させることができる。
即ち、点灯装置本体2内に配設されている発熱する電子部品である半導体19を外郭を構成するケース上蓋2a及びケース底板2bに接触させて放熱している場合、ケース上蓋2aとケース底板2bは固定金具3によって防浸ケース4に密着しているので、発熱する電子部品である半導体19からケース底板2bに伝熱した熱を防浸ケース4に伝熱して放熱効果を向上させることができる。
また、固定金具3を取り付けた点灯装置本体2を防浸ケース4内に挿着するときに、固定金具3の角部3aが点灯装置本体2の外郭上面であるケース上蓋2aの上面と防浸ケース4の内周面をそれぞれ削りながら収納されていくため、点灯装置本体2と防浸ケース4とが確実に電気的に接続される。
In this way, the fixing bracket 3 having the bent portion 3c is attached to the upper surface of the lighting device main body 2, and the lighting device main body 2 with the fixing metal fitting 3 attached thereto may be inserted into the waterproof case 4; The lighting device main body 2 is easy to assemble, and after the lighting device main body 2 is inserted into the water-proof case 4, the bending portion 3c expands due to the elasticity of the fixing bracket 3, so that the lighting device main body 2 and the water-proof case Since 4 adheres in the state pressed by the fixing metal fitting 3, the heat dissipation effect can be improved.
That is, when the semiconductor 19 which is a heat generating electronic component disposed in the lighting device body 2 is radiated by bringing it into contact with the case top lid 2a and the case bottom plate 2b constituting the outer shell, the case top lid 2a and the case bottom plate 2b Since the fixing metal fitting 3 is in close contact with the immersion case 4, heat transferred from the semiconductor 19, which is a heat generating electronic component, to the case bottom plate 2 b can be transferred to the immersion case 4 to improve the heat dissipation effect. .
Further, when the lighting device main body 2 to which the fixing bracket 3 is attached is inserted into the immersion-proof case 4, the corner 3 a of the fixing bracket 3 and the upper surface of the case upper lid 2 a that is the outer upper surface of the lighting device main body 2 are infiltrated. Since the inner peripheral surface of the case 4 is housed while being shaved, the lighting device main body 2 and the immersion case 4 are reliably electrically connected.

防浸型点灯装置1はその取付金具6の器具用取付片6cの器具用取付孔6dに挿入したネジにより器具本体9にネジ止めされている。
したがって、防浸型点灯装置1を照明器具8の器具本体9に確実に設置することができる。
