Description

本考案は、ＬＥＤ発光装置に関わり、特にフェイルオーバー機能を有する構造に関する。   The present invention relates to an LED light emitting device, and more particularly to a structure having a failover function.

どんな電子製品でも使用中に、故障する可能性があり、ＬＥＤ発光ユニットや装置も同様である。現在、ＬＥＤは屋外看板、交通標識や照明装置などの製品に幅広く用いられ、その中の一つまたは一部分のＬＥＤが故障し、点灯しない場合、こういう点灯して表される情報（例えば、文字、矢印、警告信号など）が表示されないため、見る側の識別、判別が困難、間違が生じがちである。   Any electronic product can fail during use, as are LED light emitting units and devices. Currently, LEDs are widely used in products such as outdoor signboards, traffic signs, and lighting devices, and when one or a part of the LEDs fails and does not light up, information that is lit up (for example, characters, (Arrows, warning signals, etc.) are not displayed, it is difficult to identify and discriminate the viewer, and errors are likely to occur.

現在の発光装置に設けられたＬＥＤの修理や交換を行うとき、作業の複雑さ、電気回路の膨大な接続構造または基板の組立や位置決め形態などで、通常はその作業を直ちに行う場合が多い。電気回路を正確に切断し、関連基板を取り外してから、初めて故障箇所の修理や交換を行えるようになり、例えば交通標識単一の大型交通標識には、数百個のＬＥＤユニットが設けられた場合が多く、その中、複数のＬＥＤユニットは、基板によって一つの電気回路システムが形成され、電気回路システムの間はそれぞれ、更に電気的に接続し、コントローラによって統括し、管理されるが、そこで、一つのＬＥＤユニットが故障、損壊したりした場合、該電気回路システムのＬＥＤユニットが全部点灯されなくなる恐れがあり、この場合、復旧作業は相当の時間をかけて行なわれることになり、交通標誌の警告や指示機能に与える影響が非常に大きい。   When repairing or replacing an LED provided in a current light emitting device, the task is usually performed immediately due to the complexity of the work, the huge connection structure of the electric circuit or the assembly and positioning form of the board. It is possible to repair or replace a faulty part only after the electrical circuit is accurately cut and the associated board is removed. For example, a single large traffic sign has hundreds of LED units. In many cases, a plurality of LED units form a single electric circuit system by a substrate, and each electric circuit system is further electrically connected, and is controlled and managed by a controller. If one LED unit fails or is damaged, all LED units of the electric circuit system may not be lit. In this case, the restoration work will be performed over a considerable period of time. The impact on warning and instruction functions is very large.
