AUTOMATIC LAMP DETECTION METHOD AND OPTIMAL OPERATION FOR FLUORESCENT LAMPS

摘要

There is provided a method that can detect the lamp type of fluorescent lamps and operate the lamp at the appropriate lamp power. The proposed method involves the classification of lamp characteristics of existing fluorescent lamps and the use of logic detection method such as a fuzzy logic detection and control technique to zoom into the right type of lamp. The information used in the lamp detection includes (1) lamp filament/electrode resistance, (2) lamp voltage and (3) lamp current. These three pieces of information can be used to select the appropriate fluorescent lamp type so that the control gear can operate the lamp at the right rated power. The importance of this invention can lead to a universal electronic ballast that can detect and operate all fluorescent lamps commonly available. It can also be used in a limited capacity to control a limited range of lamps.
