[0007] Therefore, in the prior art, the annular edge where the glued area of ​​the wavelength conversion sheet 22' is located can only play the role of stably fixing the wavelength conversion sheet 22' in the color wheel 2'; The area increases the area of ​​the wavelength conversion sheet, because the wavelength conversion material is expensive, and the increased area of ​​the wavelength conversion sheet increases the cost of the color wheel

[0031] Figure 5 Shown is the first embodiment of the assembly method of the color wheel of the present invention, including the following steps:

[0032]S1, stacking the wavelength conversion sheet and the first base layer, the first side of the wavelength conversion sheet is adjacent to the first base layer, the wavelength conversion sheet includes at least one wavelength conversion section, and the wavelength conversion section includes an integrally formed wavelength conversion part and at least one fixing part protruding from the outer edge of the wavelength converting part.

[0033] The wavelength conversion sheet includes at least one wavelength conversion section, and each wavelength conversion section can convert excited light different from the color of the excitation light when irradiated by the excitation light. In this step, for the convenience of operation, when the optical wavelength conversion sheet and the first base layer are stacked, they can be stacked hor...

Abstract

The invention provides a color wheel and a light source using the color wheel. The color wheel comprises a first base layer, a wavelength conversion sheet and a second base layer, which are arranged in a laminated mode, wherein the wavelength conversion sheet is positioned between the first base layer and the second base layer; the wavelength conversion sheet comprises at least one wavelength conversion section; the wavelength conversion section comprises a wavelength conversion part and at least one fixed part, which are integrally molded; the fixed part is protruded from an outer edge of the wavelength conversion part; and one side of the fixed part is fixedly connected to the first base layer or the second base layer through a first adhesive. The area of all fixed parts is much smallerthan that of an annular edge of a gluing region in the prior art. Therefore, the area of the wavelength conversion sheet is smaller, so that the cost of the color wheel can be effectively reduced.

Description

[0001] Technology field [0002] The invention relates to the technical field of light sources for illumination and display, in particular to a color wheel for illumination and display, an assembly method thereof, a light source device using the color wheel, and a projection system. Background technique [0003] At present, projectors are widely used in various occasions such as movie playback, conferences, and publicity. As we all know, in the light source of a projector, a color wheel is often used to provide a sequence of colored light. Wherein, different color segments of the color wheel are alternately and periodically arranged on the propagation path of the excitation light, and then the excitation light is used to excite the light wavelength conversion materials on the different color segments of the color wheel to generate excited light of different colors. [0004] figure 1 Shown is an existing color wheel assembly, including a color wheel 2' and a motor 1' that dri...
