1. A headlight using an image light source, comprising:
a laser light source comprising light-emitting units arranged in an array to provide an image beam; and
a wavelength converter arranged downstream of an optical path of the laser light source, wherein 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 cause a part of the image beam to be excited into an excitation beam and an unexcited part of the image beam to be mixed with the excitation beam to generate a white beam.
