Illumination module

摘要

A lighting module includes a compatible part to transform and output an output voltage from a ballast, a transformation part to transform and output an output voltage from the compatible part, and a lighting part to emit light using an output voltage from the transformation part as a driving voltage. In the compatible part, a number of ports to receive the output voltage from the ballast is different form a number of ports to output the transformed output voltage to the transformation part.
