Description

  The present invention relates to an LED light emitting device, and more particularly to a structure having a failover function.

  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.

  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.

  With regard to the problems existing in the structure of the conventional LED light emitting device described above, it is the user's desire to develop a more ideal and practical structure, so that related companies can overcome and develop it. It is also the goal and direction to strive for.

  As a technical feature to solve the problems of the present invention, it has at least one LED mounting portion and a device main body provided with one power feeding portion, at least one LED unit provided on the LED main mounting portion of the device main body, The LED unit is provided with a main light emitting circuit. The main light emitting circuit is provided with a preliminary light emitting circuit provided in the same LED unit or in a different LED unit, and an electric circuit is provided between the main light emitting circuit and the preliminary light emitting circuit. And a failover processor that is electrically connected and electrically connected to the power supply unit, the failover processor automatically detects when the main light emitting circuit is short-circuited, disconnected, or failed. The LED light emission is characterized in that the electric circuit is switched to the preliminary light emission circuit, and the light emission state of the LED unit is maintained without being interrupted. It is the location. Therefore, compared with the background art, the present invention automatically switches to the preliminary light emitting circuit when the main light emitting circuit of the LED light emitting device is short-circuited, disconnected, or failed, and keeps the light emission without interruption. The service life of the LED light emitting device and the LED unit is extended, and there is practicality and inventive step that the frequency of repair can be reduced and the cost can be reduced, and there is an industrial economic effect.

  The fact of the effect improvement by this invention is as follows.

  The [LED light emitting device with a failover function] posted in the present invention is an LED unit having a main light emitting circuit provided in the apparatus main body, and a preliminary light emitting device provided in the same LED unit or a different LED unit from the main light emitting circuit. When the main light emitting circuit is short-circuited, disconnected, or failed, the circuit and one failover processor electrically connected between the main light emitting circuit and the standby light emitting circuit automatically determine the The circuit is switched to the preliminary light emitting circuit so that the light emission is continued. Compared with [Background Art], the present invention is a unit generated when one LED unit in the conventional light emitting device fails or is cut or damaged. The present invention can improve the problem that all LED units of the electric circuit system of the present invention cannot be lit, and the present invention uses the failover processor.
