ABSTRACT:
An improved structure for LED lighting comprising an AC to DC converter, said converter comprising four rectifying diodes, and at least one LED serial set. The rectifying diodes can be divided into a first and second group, each group comprising two diodes. The negative ends of the two rectifying diodes of the first group can be connected in parallel and their positive ends can be connected with a positive and negative end of the front and rear plugs respectively. The positive ends of the two rectifying diodes of the second group can be connected together in parallel and their negative ends can be connected with the positive and negative ends of the front and rear plugs respectively. The LED serial set can be connected between the negative end of the rectifying diodes of the first group and the positive end of the rectifying diodes of the second group.
