1. A light emitting device, comprising:
a first light emitter and a second light emitter, wherein the first light emitter and the second light emitter emit lights with different color temperatures or different wavelength;
a control circuit, comprising a power distribution device, a first voltage regulator and a second voltage regulator; wherein the power distribution device comprises at least two power distribution components, and each of the power distribution components comprises two electrodes disposed independently; the at least two power distribution components are respectively a first power distribution component and a second power distribution component, one end of the first voltage regulator is electrically connected to the first light emitter, other one end of the first voltage regulator is electrically connected to the second power distribution component, one end of the second voltage regulator is electrically connected to the second power distribution component, and other one end of the second voltage regulator is electrically connected to second light emitter;
wherein the first power distribution component is electrically connected to the first light emitter, and each of the first voltage regulator and the second voltage regulator has at least one diode disposed therein;
wherein a power output end of the first voltage regulator is electrically connected to the first light emitter, and a power input end of the first voltage regulator is electrically connected to the second power distribution component; a power output end of the second voltage regulator is electrically connected to the second light emitter, and a power input end of the second voltage regulator is electrically connected to the second power distribution component;
a power supplier, the power input end of the first voltage regulator, the power input end of the second voltage regulator and the second power distribution component are electrically connected to a connection point; the one electrode of first power distribution component and the one electrode of the second power distribution component are electrically connected to the power supplier; the other one electrode of first power distribution component and the other one electrode of the second power distribution component are respectively electrically connected to the first light emitter and the connection point; and
a jumper, the jumper is configured to have a connection wire and two terminals disposed at two ends of the connection wire, when the two terminals of the jumper are respectively electrically connected to the two electrodes of the power distribution component, the jumper transmits the power provided by the power supplier to the first light emitter and/or the second light emitter.
