Embodiment Construction

[0023] Please refer to FIG. 1, FIG. 2(a), FIG. 2(b) and FIG. 4 at the same time. Since the inventive feature of the present invention focuses on the modularization technology of the color wheel, the following description only uses the color wheel in the projection device 100 The module and its surrounding components are the main components, and the rest of the components not related to the color wheel module will not be described here.

[0024] The projection device 100 in the figure mainly includes a color wheel module 200 , a power supply device (not shown in the figure), an adapter device (not shown in the figure) and a main circuit board 300 . Wherein, the color wheel module 200 is assembled on the main body 101 of the projection device 100; preferably, on the cover 110 of the top area 111 on the main body 101, and the cover 110 can be integrally pivoted on the top area in combination with the bulb cover. 111, it is convenient to open and close, and can also simplify compo...

Abstract

The invention is a projector, comprising color wheel module, where the color wheel module comprises color wheel removably mounted in the color wheel module, where the color wheel module is removable from the projector so that users can change different color wheels or clean or maintain the color wheel and the color wheel module according to different conditions and requirements.

Description

technical field [0001] The invention relates to a projection device with a replaceable color wheel, and more specifically, relates to a color wheel module provided on the projection device. Background technique [0002] Today's projection device products are very diverse. For example, digital light processing projection devices (DLP), liquid crystal projection devices (LCD) and reflective monocrystalline silicon (LCOS) projection devices, etc., each provide different consumer needs. Take the digital light processing projection device (DLP) that is common on the market as an example. The DLP projection device is based on the micro-electro-mechanical system (MEMS) electrical component (MEMS) and uses the DMD chip (digital micromirror device) developed by Texas Instruments (TI). ) as the technical basis. Generally speaking, the imaging principle of a DLP projection device is that after the light is emitted from the light source, it passes through the color wheel to perform col...
