Abstract:
A light emitting device is provided with a first LED element array and a second LED element array, each of which has one or more LED elements. The first LED element array and the second LED element array are connected in series with each other. At least one of which connected in parallel with a bypass circuit that comprises a resistor and a diode. A threshold voltage of the LED element array connected in parallel with the bypass circuit is higher than a threshold voltage of the diode, and an emission color by emission of the first LED element array is different from an emission color of light by the emission of the second LED element array.
