Title:
LIGHT EMISSION CONTROL DEVICE, LIGHT EMITTING DEVICE, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/192368
Kind Code:
A1
Abstract:
A light emission control device (10) generates output voltage by switching input voltage, and supplies a drive current based on the output voltage to a light emitting unit (20). The light emission control device generates an original control signal (CNT1) designating a lighting control section and an extinguishing control section alternately, and generates a corrected control signal (CNT2) by correcting the original control signal on the basis of the current of the light emitting unit. A switching control unit (150) switches the input voltage in the lighting control section designated by the corrected control signal, while stopping switching of the input voltage in the extinguishing control section designated by the corrected control signal.
