Abstract
A vehicle light can prevent color variations of the projected image. The vehicle light can include a laser diode, a wavelength conversion member including a phosphor configured to receive blue light emitted from the laser diode and then emitting white light, a projection lens configured to project the white light emitted from the wavelength conversion member to provide forward illumination for a vehicle, and a diffusing portion provided to the projection lens, configured to diffuse the excitation light which is incident on the projection lens from the wavelength conversion member.
