TRANSFORMER-ISOLATED LED LIGHTING CIRCUIT WITH SECONDARY-SIDE DIMMING CONTROL |
摘要 |
A transformer isolated LED lighting circuit supplies current from a secondary-side storage capacitor to one or more LED strings in conformity with one or more dimming values. The dimming values are communicated through the transformer by patterns or codes provided in pulses of a power converter circuit that charges the storage capacitor from the primary side of the transformer, or alternatively by a special modulated signal provided in addition to the switching pulses.
