Abstract

The invention relates to a fluorescent agent color wheel and a light source system using the fluorescent agent color wheel. The fluorescent agent color wheel at least comprises glass, a first fluorescent agent and a first light filtering sheet. The glass is provided with a first segment. The first fluorescent agent coats the first segment. First wave band light is converted into second wave band light in terms of structure. The first light filtering sheet is arranged to be adjacent to the first segment and used for filtering part of first light beams of the first wave band light and the second wave band light so that a second light beam of the second wave band light emits out by penetrating through the first light filtering sheet. The second wave band light is yellow and the first fluorescent agent is a yellow fluorescent agent. The first filtering sheet is a red light filtering sheet. Thus, the manufacturing cost is effectively reduced, the luminance of red light is improved along with boosting of drive currents, therefore, the overall luminance of the light source system is improved and image quality is modified.

Description

technical field [0001] The invention relates to a color wheel, in particular to a fluorescent agent color wheel and an applicable light source system. Background technique [0002] In recent years, various projectors have been widely used in homes, schools, or various business occasions for amplifying and displaying an image signal provided by an image signal source on a screen. In order to save power consumption and reduce the size of the device, the current projector's light source system (Illumination System) has used solid-state light-emitting elements, such as light-emitting diodes or laser elements, to replace traditional high-density gas discharge lamps (HID Lamp) or high-pressure mercury lamps . [0003] The light source system of the projector needs to be able to emit three primary colors of light such as red light, green light, and blue light (R, G, B). However, the luminous efficiency of solid-state light-emitting elements is generally blue. The luminous efficien...
