Abstract:
1. A light-emitting device having an equivalent circuit, comprising: at least four terminals, numbered from first terminal to fourth terminal, for electrical power feeding; a first light-emitting diode, arranged between the first terminal and the second terminal, is configured to not emit light when a voltage is applied between the second terminal and one of the third terminal and fourth terminal and configured to emit light when a voltage is applied between the first terminal and one of the third terminal and the fourth terminal; and a second light-emitting diode, electrically connected to the first light-emitting diode in series, arranged between the third terminal and the fourth terminal, and configured to not emit light when the voltage is applied between the third terminal and one of the first terminal or the second terminal and configured to emit light when a voltage is applied between the fourth terminal and one of the first terminal and the second terminal.
