Disclosed is a lamp control device. The lamp control device may include: a lamp having an LED channel; a channel resistor corresponding to the LED channel; and a controller configured to boost a channel resistor voltage applied to the channel resistor, and retain a channel current of the LED channel as a target current, using the boosted channel resistor voltage.

Lamp control device

Provided is a lighting apparatus. The lighting apparatus may provide an output voltage to lighting loads, and include: a converter configured to generate the output voltage using a driving signal; and a driving circuit configured to provide the driving signal, and spread the frequency of the driving signal by performing frequency dithering on the driving signal while changing the shape of an oscillation signal.

Lighting apparatus and driving circuit including frequency dithering and slope compensation

A lamp control device may include: a lamp including an LED module having a plurality of LED channels; a converter configured to receive a voltage corresponding to a turn signal, convert the voltage into an output voltage and internal voltage, and supply the output voltage to the LED module; and a controller configured to start counting a preset delay time when the internal voltage is supplied from the converter, and control the plurality of LED channels to sequentially light up at intervals of the delay time.
