Stack light with modular power converter

摘要

A power converter (56) is introduced into a stack light (10) in the form of a compatible modular element (14) that fits between the base (16) and a light module (12). By converting multiple input voltages to a common core voltage in a module (14) distinct from the base (16) and light modules (12), proliferation of different varieties of base modules (16) and light modules (12) may be reduced without impact on customer selection.
