Abstract
(EN)
A light source system (100, 200, 300) and a projection apparatus. The light source system (100, 200, 300) comprises: a light source, comprising a first light source (111, 211, 311); a wavelength conversion apparatus (130, 230, 330); a light concentrating apparatus (120, 220, 320), comprising a light concentrating lens (121), with the light concentrating lens (121) being used for concentrating excitation light emitted from the first light source (111, 211, 311) onto the wavelength conversion apparatus (130, 230, 330); and a light deflection apparatus (140, 240, 340), wherein same is arranged in a light path between the first light source (111, 211, 311) and the wavelength conversion apparatus (130, 230, 330) in a time division manner, and is used for deflecting some of the light beams emitted from the first light source (111, 211, 311), so as to adjust the area of light spots that are irradiated by the first light source (111, 211, 311) onto the wavelength conversion apparatus (130, 230, 330). The light source system (100, 200, 300) can improve the light conversion efficiency of excitation light.

La présente invention concerne un système de source de lumière (100, 200, 300) et un système de projection. Le système de source de lumière (100, 200, 300) comprend : une source de lumière comprenant une première source de lumière (111, 211, 311) ; un appareil de conversion de longueur d'onde (130, 230, 330) ; un appareil de concentration de lumière (120, 220, 320) comprenant une lentille de concentration de lumière (121), la lentille de concentration de lumière (121) servant à concentrer la lumière d'excitation émise par la première source de lumière (111, 211, 311) sur l'appareil de conversion de longueur d'onde (130, 230, 330) ; et un appareil de déviation de lumière (140, 240, 340), celui-ci étant disposé dans un trajet de lumière situé entre la première source de lumière (111, 211, 311) et l'appareil de conversion de longueur d'onde (130, 230, 330) d'une manière à répartition dans le temps, et il sert à dévier certains des faisceaux de lumière émis par la première source de lumière (111, 211, 311) de façon à régler la zone de points lumineux qui sont irradiés par la première source de lumière (111, 211, 311) sur l'appareil de conversion de longueur d'onde (130, 230, 330). Le système de source de lumière (100, 200, 300) permet d'améliorer l'efficacité de conversion de lumière de la lumière d'excitation.
