Problems solved by technology

[0007] The main purpose of the present invention is to provide a fluorescent agent device and its applicable light source system, so as to solve the problem that the existing fluorescent agent device is difficult to manufacture due to the mixing of phosphor powder, and the cascade effect causes poor light extraction efficiency and color saturation. Insufficient and color cast phenomenon and other shortcomings

Abstract

The invention provides a fluorescent agent device and an applicable light source system thereof. The fluorescent agent device is applicable to the light source system emitting first band light and comprises a first section and n single-powder fluorescent agents. The first section comprises n sub-sections, wherein n is greater than or equal to 2; and the n single-powder fluorescent agents are coated on the n sub-sections so that first band light is converted into n band light. The n sub-sections have specific area proportion. First band light is converted into second band light, third band light,...(n+1)th band light in a cycle way according to the specific area proportion and specific time proportion. n band light emitted in a time-sharing way according to the specific time proportion is integrated into specific color light. With the design that each section comprises more than two sub-sections, cascade effect caused by powder mixing can be effectively avoided, converted light emergent efficiency and light color diversity can beenhanced, and effects of enhancing color saturation and brightness of emergent color light are achieved simultaneously.

Description

technical field [0001] The invention relates to a fluorescer device, in particular to a fluorescer device which improves light extraction efficiency and light color diversity by combining a plurality of color band regions and an applicable light source system. Background technique [0002] In recent years, various projection devices, such as projectors, have been widely used in families, schools or various business occasions to enlarge and display 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 light source system (Illumination System) of the current projection equipment has used solid-state light-emitting elements, such as light-emitting diodes or laser elements, to replace the existing high-density gas discharge lamp (HID Lamp) or high-pressure mercury lamp. [0003] The light source system of projection equipment needs to be able to emit three primary colors of light such as red ...
