Abstract:
1. An energy saving lamp comprising: a main body defining an accommodating hole; a circuit comprising a plurality of parallel loops, each parallel loop comprising at least one light emitting member and a pair of open ends, the pair of open ends being spaced from each other, and being exposing in the accommodating hole; an adjusting member being rotatably connected to the main body; a shielding device being fixed on the adjusting member; a conductive rod being fixed at the shielding device, and being received in the accommodating hole of the main body; when the adjusting member turns under a twisting force, it drives the shielding device to turn, the conductive rod moving in the accommodating hole to contact different number of the pairs of open ends to close the loops of the open ends, the at least one member in the closed loops are thus turned on.
