Light emitting diodes (LEDs) are semiconductor materials made of Ga (gallium), P (phosphorus), and As (arsenic). It has the characteristics of a diode. When current is applied, it emits red, green and yellow light. It is most suitable for peak indicator or numeric display because it has a longer lifetime than the bulb and has the advantage that the response speed (the time until the current flows to the light) can be made fast and various shapes.

However, when one light emitting diode shown in FIG. 1 is inoperable, there is a problem that the entire LED needs to be replaced.

Therefore, there is a case where the relay is designed to be switched to another diode with the conventional design, but in such a case, a complicated circuit is formed, and durability and reliability can not be secured.
