Description

[Detailed Description of the Invention] (Technical Field to which the Invention Pertains) The present invention comprises a predetermined number of indicator light circuits, each of which uses a light emitting diode (hereinafter abbreviated as LED) as a light source and is connected to a balancing circuit, in the same device. It relates to an indicator light device.

(Prior art and its problems) LMDs have a long lifespan, so they are suitable as light sources for indicator light devices. Furthermore, since there are LEDs with different light colors, it is possible to separate them and configure a plurality of circuits with different light colors within the same frame. However, since LhiD has polarity, when used in an r#L flow circuit, wiring must be done paying attention to the polarity.

Furthermore, when connecting multiple circuits, it is common to connect one terminal in common in order not to reduce the number of wires. When multiple circuits are housed in the same indicator light device as in this case, there are many types of circuit configurations, and it is necessary to keep indicator light devices with each circuit configuration on hand or to change the connections every time the IIS is used. There is a drawback.

(Purpose of the invention) The present invention has an indicator light containing ≠6 LEDs.
