Embodiment Construction
[0025] Next, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Here, elements that are identical, similar, or have the same or similar effect are denoted by the same reference numerals in the figures. Duplicated descriptions may therefore be omitted in order to prevent redundant descriptions.
[0026] image 3 The general structure of an electronic transformer 1 for improved compatibility is schematically shown. The transformer 1 is particularly suitable for operating one or more low power LED lamps 2 .
[0027] The transformer 1 receives AC power (ie alternating current) through input ports P1, P2. The transformer 1 is configured to convert the AC voltage into a substantially DC (ie, direct current) current, which is then transformed to operate the LED lamp 2 . To this end, the transformer 1 comprises a rectifier circuit 3 and two stages, namely a first stage 10 and a second stage 20 . The rectifier circuit 3 ca...
