  • the 210 and the color wheel assembly 230 are located on both sides of the mirror 220, since the light passing port 200 is disposed at the center of the mirror 220 For passing the excitation light, a part of the fluorescence is not reflected on the color correction area, resulting in light loss, and in the case shown in Fig. 7, the mirror 320 is intact, so there is no light loss.
  • the mirror is opposite to the color wheel assembly 230 After tilting, that is, rotating a certain angle around the apex of its concave reflecting surface, the fluorescence can directly converge on the color repairing area on the color wheel, thereby removing the original collected fluorescence and replacing the large angle light into a small angle light.
  • the square rod reduces the volume of the light source system, simplifies the structure, and miniaturizes the light source system.
  • the embodiment of the present application further provides a projector, which includes the above light source system, reduces the volume of the projector, and can realize 3D at the same time.

Abstract

La présente invention se rapporte à un système source de lumière et à un projecteur. Le système source de lumière comprend : un ensemble roue de couleur, l'ensemble roue de couleur comportant une roue lumineuse fluorescente; un appareil source de lumière, l'appareil source de lumière servant à émettre une lumière d'excitation, la lumière d'excitation formant un point lumineux agrégé sur la roue lumineuse fluorescente et excitant cette roue lumineuse fluorescente pour générer de la lumière fluorescente; un miroir réfléchissant, le miroir réfléchissant possédant une ouverture qui fait face au côté réfléchissant concave de l'ensemble roue de couleur, ce miroir réfléchissant étant disposé obliquement par rapport audit ensemble roue de couleur et servant à réfléchir la lumière fluorescente vers l'extérieur de la roue lumineuse fluorescente. Dans le système source de lumière, grâce à la disposition oblique du miroir réfléchissant par rapport à l'ensemble roue de couleur, la lumière fluorescente est réfléchie par ce miroir réfléchissant vers l'extérieur de la roue lumineuse fluorescente, ce qui permet d'éliminer la tige carrée dans la structure du système, et de réduire considérablement le volume dudit système source de lumière. La présente invention a trait également à un projecteur qui comprend le système source de lumière, et qui réduit considérablement le volume de ce système source de lumière.
