Abstract
Description
本発明は、回路部品実装に考慮を加えた照明器具に関する。 The present invention relates to a lighting fixture that takes into account circuit component mounting.
特許文献1には、部品を下面に実装した基板を本体の下面に配置し、その下面を反射板で覆い、さらに反射板の下面に環状の蛍光ランプを設けた照明器具であって、反射板の下面全体を斜め上方に向かう傾斜面とし、前記部品を傾斜面の外周付近よりは内周側に実装した照明器具が示される。
しかし、チップタイプの部品実装については何らの開示がなく、基板への部品実装密度を向上することは別段考慮されていない。従って、本発明は、反射板の形状に対応して基板への実装密度を向上することを目的とする。 However, there is no disclosure about chip-type component mounting, and no particular consideration is given to improving the component mounting density on the substrate. Accordingly, an object of the present invention is to improve the mounting density on the substrate in accordance with the shape of the reflector.
本発明を要約すると、リード線タイプの第一部品を下面に実装しチップタイプの第二部品を上面に実装した基板を本体の下面に配置し、その下面を金属製の反射板で覆い、さらに反射板の下面に環状の蛍光ランプを設けた照明器具であって、反射板の下面外周部を斜め上方に向かう傾斜面とし、第一部品のうち背の高い部品を傾斜面より内周側に実装し、第二部品は傾斜面の上方にも実装した照明器具である。 To summarize the present invention, a substrate having a lead wire type first component mounted on the lower surface and a chip type second component mounted on the upper surface is disposed on the lower surface of the main body, and the lower surface is covered with a metal reflector, A lighting fixture provided with an annular fluorescent lamp on the lower surface of the reflecting plate, wherein the lower surface outer peripheral portion of the reflecting plate is inclined obliquely upward, and the taller component of the first component is located on the inner peripheral side from the inclined surface. The lighting device is mounted and the second component is also mounted above the inclined surface.
本発明によれば、第一部品のうち背の高い部品を傾斜面より内周側に実装したため、傾斜面(金属製)との絶縁距離を確保しやすく、第二部品は傾斜面の上方にも実装したため、第二部品を広い範囲に渡って多数実装可能になった。 According to the present invention, since the tall part of the first part is mounted on the inner peripheral side from the inclined surface, it is easy to secure an insulation distance from the inclined surface (made of metal), and the second component is located above the inclined surface. As a result, a large number of second parts can be mounted over a wide range.
次に、本発明の実施形態を説明するが、それはあくまで本発明に基づいて採択された例示的な実施形態であり、本発明をその実施形態に特有な事項に基づいて限定解釈してはならず、本発明の技術的範囲は、特許請求の範囲の請求項に示した事項さらにはその事項と実質的に等価である事項に基づいて定めなければならない。 Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention should not be limitedly interpreted based on matters specific to the embodiment. The technical scope of the present invention should be determined based on the matters shown in the claims of the claims and matters substantially equivalent to the matters.
図示の実施形態は、リード線タイプの第一部品1…(大型抵抗、コンデンサ、コイル、半固定抵抗など)を下面に実装しチップタイプの第二部品(超小型チップ抵抗など;複雑化するため図示せず)を上面に実装した基板2を金属製の本体3の下面に配置し、その下面を金属製の反射板4で覆い、さらに反射板4の下面に環状の蛍光ランプ5を設けた照明器具である。
In the illustrated embodiment, a lead-type first component 1 (large resistor, capacitor, coil, semi-fixed resistor, etc.) is mounted on the lower surface, and a chip-type second component (ultra-small chip resistor, etc .; for complexity) A
そして、反射板4の下面外周部を斜め上方に向かう傾斜面6とし、第一部品1…のうち背の高い部品(大型抵抗、コンデンサ、コイルなど)を傾斜面6より内周側に実装し、第二部品は傾斜面6の上方にも実装している。なお、半固定抵抗などの比較的背の低い第一部品は基板2において傾斜面6の上方に実装してもよい。また、第二部品は基板2の上面全体に平均的に分散実装されるとよい。
And the lower surface outer peripheral part of the
さらに他の構成を述べると、本体3は天井に適宜手段で取り付けられ、蛍光ランプ5は本体3に取り付けたソケット7から給電されて点灯可能となっている。
