Abstract
A headlight using an image light source is provided, which includes a laser light source and a wavelength converter. The laser light source includes multiple light-emitting units arranged in an array to provide an image beam. The wavelength converter is arranged downstream of an optical path of the laser light source. The wavelength converter is provided with a light dot matrix with the number of rows and columns greater than or equal to 40×40 to excite a part of the image beam into an excitation beam, and an unexcited part of the image beam is mixed with the excitation beam to generate a white beam.
