Title:
高輝度パルス光源構成
Document Type and Number:
Japanese Patent JP5586440
Kind Code:
B2
Abstract:
A high-intensity light source configuration has a long lifetime and can be modulated at a high rate. The configuration includes a movable member mounted to an actuator; a light-emitting phosphor region associated with the movable member; an input light source that illuminates the light-emitting phosphor region at a spot that is fixed relative to an emitted light output region; and a light source controller controlling the movable member actuator and the input light source. The input light source (e.g., laser) provides high-intensity input light to the illuminated spot, causing the light-emitting phosphor region to emit high-intensity output light. The light-emitting phosphor region is moved relative to the illuminated spot so as to reduce optical quenching and photobleaching, to thereby extend the life of the light source configuration. The phosphor region may emit broadband light and/or may include respective sub-regions having phosphors that emit respective peak wavelengths.
