摘要

A linear light emitting diode (LED) module with multiple parallel LED strings driven by a constant current source could display luminous flux variations along its length. This effect is caused by current imbalance among LED strings. Three commonly used electrical connection methods were compared and analyzed with computer simulations and actual experiments. Recommendations are made on how to minimize the imbalance.
