Embodiment Construction

[0038] First of all, it needs to be explained that, in the accompanying drawings of the present invention, Figure 1a , Figure 1b , figure 2 with image 3 Shown are the cross-sectional views of the color wheels of the first three embodiments of the present invention. Since most of the components in the color wheel of the present invention are rotationally symmetrical, it is sufficient to use a sectional view to describe its entire structure. It is worth mentioning that in Figure 1a , Figure 1b , figure 2 with image 3 The bolts and corresponding threaded holes are not distributed rotationally symmetrically, but at least two are distributed symmetrically or asymmetrically along the direction of rotation, wherein the bolts and threaded holes are preferably distributed symmetrically, which helps the entire color wheel dynamic balance.

[0039] In the fourth embodiment of the present invention, the color wheel structure of the third embodiment is used, Figure 4a The p...

Abstract

The invention provides a color wheel and an assembly method therefore, and a light-emitting device based on the color wheel. The color wheel comprises a first wheel disc, a second wheel disc, a motor in a specific shape, a switchover piece in a specific shape and a compression ring; a second cylindrical surface of an inner surface of the switchover piece and a first cylindrical surface of the surface of the motor are positioned coaxially, the first wheel disc is coaxial with the switchover piece, and the second wheel disc is coaxial with the switchover piece or the motor, so that main parts of the whole color wheel can be coaxial with one another to ensure the dynamic balance of the color wheel in the high-speed rotating process; and simultaneously, the second wheel disc and the switchover piece are tightly compressed and fixed by using pressure between a part of the compression ring on a second fixed surface of the motor, which is protruded out of the second fixed surface, and a first fixed surface of the motor, so that the advantage of convenience in assembly and disassembly is realized on the basis of ensuring the stability of a system.

Description

technical field [0001] The invention relates to the field of projection display, in particular to a color wheel and a light emitting device. Background technique [0002] In the existing projection display technology, there are two mainstream schemes. One is to use white light to be incident on a filter color wheel composed of red, green and blue multicolor filters. White light is filtered to become monochromatic light of red, green and blue; the other is to use a beam of excitation light incident on a fluorescent color wheel coated with a multi-color phosphor coating, and sequentially excite and emit multi-color as the color wheel rotates fluorescence. [0003] In the second solution, the monochromatic light emitted by the phosphor is often not bright enough, so it is necessary to use a filter to modify its emission spectrum to meet the display requirements. Since the properties of the filters required for each monochromatic light are different, a corresponding filter col...
