Problems solved by technology

[0004] However, in the prior art, since the sensing parts of the sensing module do not have any protective measures, if it is used for too long in a country with a lot of wind and sand or dust, it will cause dust to accumulate inside the sensing module, which will cause The projector device flickers or shuts down, affecting the use of the projector device and shortening the life of the projector device

Abstract

The invention discloses a projector device. The projector device comprises a color wheel module, a sensing module and a transparent plate body, wherein the color wheel module comprises a color wheel, a motor and a color wheel bracket; the motor is used for rotating the color wheel; the color wheel is rotatably fixed on the color wheel bracket; the color wheel bracket is provided with a first plate body; an opening is formed on the first plate body; the sensing module is used for sensing the color wheel to generate a color wheel sensing signal, comprises a sensing element, is fixed on the color wheel bracket, and is opposite to the opening; and the transparent plate body is attached to and fixedly arranged on the first plate body and covers the opening. The projector device can prevent dust from being accumulated in the color wheel bracket and the sensing module under the condition of not influencing the sensitivity of the sensing element.

Description

technical field [0001] The present invention relates to a projector device, in particular to a projector device capable of effectively isolating sand and dust. Background technique [0002] The projector device includes a light source, a display element, a control unit, a projection lens, and a color wheel module. The light source provides an illumination beam. The color wheel module is arranged on the transmission path of the illumination beam. On the transmission path after the assembly, the display element is, for example, a digital micromirror device. The color wheel of the color wheel module, that is, the filter assembly, includes a plurality of filters of different colors, such as red filters, green filters, and blue filters. The control unit of the projector device drives the motor to drive the color wheel to rotate, and as the color wheel rotates, the illumination light beam passing through the color wheel is sequentially filtered into red light, green light and blu...
