US 2017/0303352 A1 · LAMP CONTROL DEVICE

Abstract

A lamp control device includes a lamp including an LED module which has a plurality of LED channels; and a controller configured to detect respective feedback voltages of the plurality of LED channels, and determine, when at least any one feedback voltage among the feedback voltages is retained to be lower than a predetermined reference voltage and a generation count of an over voltage protection signal reaches a predetermined reference count, an LED channel corresponding to the feedback voltage, as an open.
