LIGHT SOURCE UNIT AND VEHICULAR LAMP

Japanese Patent JP2018113234

A

PROBLEM TO BE SOLVED: To reduce difference between a hue of light emitted from a first light-emitting element and a hue of light emitted from a second light-emitting element, to improve visibility.SOLUTION: A light source unit includes a first light-emitting element 28 and a second light-emitting element 29, which are mounted on a substrate 27 in a state of being sealed in a fluorescent body 32, wherein light emission intensity of the first light-emitting element is made smaller than light emission intensity of the second light-emitting element, and a light-emitting area of the first light-emitting element is made smaller than a light-emitting area of the second light-emitting element. Consequently, since the light-emitting area of the first light-emitting element having light emission intensity smaller than the second light-emitting element is made smaller than the light-emitting area of the second light-emitting element, difference between a hue of light emitted from the first light-emitting element and a hue of light emitted from the second light-emitting element can be reduced to improve visibility.SELECTED DRAWING: Figure 3
