Light emitting device unit for AC voltage
First Claim
1. A light emitting diode unit for alternating current (AC) voltage, the light emitting diode unit comprising:
- a sub-mount, on which electric wires are formed;
a first light emitting diode array in which a plurality of first light emitting diodes are serially connected to the sub-mount; and
a second light emitting diode array, in which a plurality of second light emitting diodes are connected to the sub-mount in the form of a bridge circuit connecting to the first light emitting diode array.

Abstract
A light emitting diode unit for AC voltage is provided. The light emitting diode unit includes a sub-mount on which electric wires are formed; a first light emitting diode array in which a plurality of first light emitting diodes are serially connected to the sub-mount; and a second light emitting diode array, in which a plurality of second light emitting diodes are connected to the sub-mount as bridge circuits, connecting to the first light emitting diode array. Therefore, rectification can be performed through the bridge circuit without an additional rectifying device by connecting the light emitting diodes to the bridge circuit in series, and thus the structure of the unit can be simplified and a size of the light emitting diode unit can be reduced.
