Control circuit for a lighting device, lighting device including the control circuit, and control apparatus including the control circuit for a lighting device

Abstract

A control circuit for a lighting device, a lighting device including the control circuit, and a control apparatus having a control circuit for a lighting device installed are disclosed. The invention comprises a cutoff unit configured to ground supply lines which supply current to all lighting modules except a first lighting module among a plurality of lighting modules, when current flows through a first supply line that supplies current to the first lighting module configured to emit light in a first color among the plurality of lighting modules each configured to emit light in different colors. When current is supplied through a supply line connected to a specific lighting module among a plurality of lighting modules for the intended operation of the lighting device, a malfunction of the lighting device may be effectively prevented by fundamentally blocking the supply of current through all supply lines except the specific supply line.
