Abstract:
The present invention relates to a light emitting device. In the light emitting device of the present invention, light emitting cells of a first light emitting cell block and light emitting cells of a second light emitting cell block corresponding thereto are connected in parallel so that a current can cross the light emitting cells of the first and second light emitting cell blocks. Thus, even though a leakage current occurs in some of light emitting cells, the current is allowed to cross light emitting cells connected in another direction, thereby preventing overload on some of the light emitting cells due to the leakage current and ensuring uniform light emission and prolonged life span in the AC light emitting device.
