Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A projection type vehicle light configured to project light forward, comprising: a light source including a semiconductor light-emitting element; a wavelength conversion member including a phosphor configured to receive excitation light emitted from the semiconductor light-emitting element and emit visible light, and a metal plate configured to support the phosphor and have a mirror top surface so that the visible light emitted downward from the phosphor i…
