Abstract
(EN)
A light source system (100) and a projection device. The light source system (100) comprises: a first light source (110) for emitting excitation light; a second light source (120) for emitting laser light as supplemental light; and a wavelength conversion element (150), comprising a conversion area (152), wherein the conversion area (152) is used for performing wavelength conversion on the excitation light emitted from the first light source (110) so as to obtain excited light. The excited light emitted from the wavelength conversion element (150) and the supplemental light emitted from the second light source (120) are arranged side by side at an entrance of a light homogenizing apparatus (180), thereby reducing the loss of the excited light and improving the lighting efficiency when the excited light is combined with the supplemental light.

L'invention concerne un système de source de lumière (100) et un dispositif de projection. Le système de source de lumière (100) comprend : une première source de lumière (110) servant à émettre une lumière d'excitation ; une seconde source de lumière (120) servant à émettre une lumière laser en tant que lumière supplémentaire ; et un élément de conversion de longueur d'onde (150) comprenant une zone de conversion (152), la zone de conversion (152) servant à effectuer une conversion de longueur d'onde sur la lumière d'excitation émise par la première source de lumière (110) de façon à obtenir une lumière excitée. La lumière excitée émise par l'élément de conversion de longueur d'onde (150) et la lumière supplémentaire émise par la seconde source de lumière (120) sont disposées côte à côte au niveau d'une entrée d'un appareil d'homogénéisation de lumière (180), ce qui permet de réduire la perte de lumière excitée et d'améliorer l'efficacité d'éclairage lorsque la lumière excitée est combinée à la lumière supplémentaire.
