Embodiment Construction

[0027] See figure 1 , figure 1 It is a structural schematic diagram of an embodiment of the light source system of the present invention. Such as figure 1 As shown, the light source system 100 of this embodiment mainly includes a light source 101 , a light concentrating device 102 , a light collecting device 103 , a color wheel 104 , a driving device 105 and a light homogenizing device 106 .

[0028] Such as figure 1 As shown, the light source 101 generates excitation light, and the excitation light is collected by the light collecting device 102 and then incident on the color wheel 104 through the opening of the light collecting device 103 after being concentrated. The driving device 105 drives the color wheel 104 so that the light spot formed by the excitation light on the color wheel 104 acts on the color wheel 104 along a first path.

[0029] In this embodiment, the light source 101 may be a solid-state light source such as an LED or a laser tube. The light collecting...

Abstract

The invention provides a light source system and a projection device. The light source system comprises a light source, a color wheel and a driving device. The light source is used to generate exciting light; at least two types of functional materials are arranged on the color wheel; the driving device is used to drive the color wheel to enable light spots formed on the color wheel by the exciting light to act on the color wheel along a first path and at the same time to irradiate the functional materials (at least two types), so that the exciting light can generate a type of output light under the action of each type of functional material (at least two types); and the output light generated by the functional materials (at least two types) is different in color. The functional materials (at least two types) are arranged at different areas of the color wheel or the functional materials are arranged in a blended manner, and the proportion of the functional materials within the light spots is uneven. Through the manner, the light source system and the projection device can avoid the interference among the functional materials while output light with different colors is generated at the same time.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a light source system and a projection device. Background technique [0002] Currently, monochromatic lights of different colors are often used in the field of lighting and display. In the prior art, different fluorescent segments of the color wheel are generally excited by the excitation light generated by the excitation light source to generate monochromatic light of different colors. Wherein, each fluorescent section of the color wheel is provided with different fluorescent materials, and the driving device is used to drive the color wheel to rotate so that each fluorescent section is alternately arranged on the transmission path of the excitation light, thereby alternately generating monochromatic colors of different colors at different time periods. Light. Sometimes, the luminous effect of a single color wavelength conversion material is not enough to meet the requirement...
