Title
(EN) LIGHT SOURCE FOR PROJECTION DISPLAY
(FR) SOURCE DE LUMIÈRE POUR ÉCRAN DE PROJECTION
(ZH) 一种投影显示光源
Abstract
(EN)
A light source for projection display at least comprises: a first laser source (201), a second laser source (202), a third laser source (203), a beam combining lens (204), and a fluorescent powder wheel (205) coated with fluorescent powder. By using the light source for projection display of the present invention, the overall volume of a light source for projection display can be effectively reduced and the production cost of a light source for projection display is lowered.
(FR)
La présente invention concerne une source de lumière pour un écran de projection qui comprend au moins : une première source laser (201), une deuxième source laser (202), une troisième source laser (203), une lentille de combinaison de faisceaux (204) et une roue à poudre fluorescente (205) revêtue d'une poudre fluorescente. Par l'utilisation de la source de lumière pour écran de projection de la présente invention, le volume total d'une source de lumière pour écran de projection peut être efficacement réduit et le coût de production d'une source de lumière pour écran de projection est réduit.
