要約
(EN)
This light source device (100) is provided with a semiconductor light-emitting element (101), a condenser optical system (102) for condensing excitation light (121) emitted from the semiconductor light-emitting element (101), and a wavelength conversion element (103) on which the excitation light (121) is irradiated. The wavelength conversion element (103) is provided with a first wavelength conversion region (111) on which a main light ray (122) is incident, and a second wavelength conversion region (112) on which excitation light (121) other than the main light ray (122) is incident, the second wavelength conversion region (112) being disposed around the first wavelength conversion region (111), the wavelength conversion efficiency of the second wavelength conversion region (112) being less than that of the first wavelength conversion region (111).

L'invention concerne un dispositif de source de lumière (100) comprenant un élément émetteur de lumière à semi-conducteur (101), un système optique de condensateur (102) permettant de condenser la lumière d'excitation (121) émise à partir de l'élément émetteur de lumière à semi-conducteur (101), et un élément de conversion de longueur d'onde (103) sur lequel la lumière d'excitation (121) est irradiée. L'élément de conversion de longueur d'onde (103) est doté d'une première région de conversion de longueur d'onde (111) sur laquelle un rayon lumineux principal (122) est incident, et d'une seconde région de conversion de longueur d'onde (112) sur laquelle une lumière d'excitation (121) autre que le rayon lumineux principal (122) est incidente, la seconde région de conversion de longueur d'onde (112) étant disposée autour de la première région de conversion de longueur d'onde (111), l'efficacité de conversion de longueur d'onde de la seconde région de conversion de longueur d'onde (112) étant inférieure à celle de la première région de conversion de longueur d'onde (111).
