摘要： A light module having a first power line, a second power line, and light devices. The first power line is connected to a first power point. The second power line is connected to a second power point. Each light device having a first terminal coupled to the first power line and a second terminal coupled to the second power line. A first sum of a first line length between the first power point and the first terminal of any of the light devices and a second line length between the second power point and the second terminal thereof is substantially a first constant.

摘要： An inverter for driving multiple discharge lamps. The inverter has a transformer for driving a first discharge lamp and a second discharge lamp. The inverter also includes a first balancing circuit connected in series with the first discharge lamp and a second balancing circuit connected in series with the second discharge lamp. According to a matching signal, the first and the second balancing circuits adjust a first lamp current through the first discharge lamp and a second lamp current through the second discharge lamp, respectively. A comparator is provided to receive a first sensing signal from the first balancing circuit and a second sensing signal from the second balancing circuit. Comparing the first sensing signal with the second sensing signal, the comparator generates the matching signal which controls the first and the second balancing circuits to equalize the first lamp current and the second lamp current.
