LIGHT DISTRIBUTION CONTROLLER, LIGHT PROJECTION SYSTEM, AND LIGHT DISTRIBUTION CONTROL METHOD

摘要

To provide a light distribution controller, a light projection system, and a light distribution control method that allow a desired subject to be perceived while securing distant visibility.SOLUTION: A light distribution controller 100 includes: visible light irradiation means 30 for radiating visible light; infrared-ray irradiation means 40 for radiating an infrared ray on an upper side above a low beam region, as an infrared-ray irradiation region, out of a region irradiated with visible light by the visible light irradiation means 30; and control means 61 for controlling the visible light irradiation means 30 and the infrared-ray irradiation means 40. The control means 61 divides the infrared-ray irradiation region into an upper region and a lower region, and controls the infrared-ray irradiation means 40 so that an infrared-ray intensity of the upper region is weaker than an infrared-ray intensity of the lower region.SELECTED DRAWING: Figure 1
