Disclosed is a light emitting device configured in such a manner that all light emitting elements always emit light irrespective of the magnitude of a voltage when the magnitude of the voltage is higher than the minimum light emitting voltage, that the light emitting elements are connected to each other in parallel when the magnitude of the voltage gets smaller, and that the light emitting elements are connected to each other in series when the magnitude of the voltage gets larger. |
