Title:
VEHICLE LAMP
Document Type and Number:
Japanese Patent JP2015153645
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicle lamp forming a light intensity distribution having a relatively high light intensity in a partial region.SOLUTION: A vehicle lamp comprises: an excitation light source 12; a light polariscope 201 that includes a mirror section reflecting excitation light incident from the excitation light source and that two-dimensionally scans the excitation light by the mirror section by resonance drive and non-resonance drive; a wavelength conversion member 18 including a scan region in which a light intensity distribution is formed by drawing a two-dimensional image by the excitation light two-dimensionally scanned by the mirror section; a control unit exerting a control to form the two-dimensional image in the scan region by the excitation light scanned two-dimensionally by the mirror section; and an optical system 20 projecting the light intensity distribution formed in the scan region and forming a predetermined light distribution pattern, the control unit forming a light intensity distribution in which a light intensity is relatively high in a partial region in the scan region by exerting a control so that a speed of reciprocating swing of the mirror section is relatively slow while the two-dimensional image is drawn in the partial region in the scan region by the excitation light scanned two-dimensionally by the mirror section.
