Abstract

The invention provides projector, which includes multiple first optical elements, a light machine housing, a color wheel module and a color wheel cover body. The first optical elements are used for providing and/or transmitting light. The light machine housing is used for arranging the first optical elements. The light machine housing is equipped with a first cavity and a first opening, which are communicated with each other. The color wheel module is disposed in the first opening, and at least part of the color wheel module extends into the first cavity through the first opening. The color wheel cover body is used for covering the part of the color wheel module that is exposed from the first cavity and covering the first opening. The part of the color wheel module, positioned in the first cavity, is on a transmitting part of light to carry out wavelength conversion or splitting for the light. The color wheel module is directly combined with the light machine housing, so the color wheel module extending into the light machine housing is positioned on the transmitting part of the light. In this way, the brightness is prevented from being reduced.

Description

Scialyscope

Technical field

The present invention relates to field of projector, more particularly to a kind of scialyscope for improving brightness.

Background technology

The technology of DLP projector is a kind of full-digital reflective shadow casting technique.Its feature is Digital Advantage first.Digital skill The employing of art, improves gradation of image grade, and picture noise disappears, and image quality is stable, and digital picture is very accurate.Next to that Reflection advantage.DLP projector high definition, picture are uniform, and color is sharp keen, fine and smooth, naturally true to nature, and three machines can reach very high Brightness, and can random zoom, adjust very convenient.

The operation principle of DLP projector is the illuminating bundle for being sent light source, through the colour wheel module that rotates by light It is filtered into after three kinds of colors of red, green, blue and is delivered to display module to be converted into image strip, then by projection lens by image strip It is projected on screen and forms picture, so as to provides splendid visual effect for spectator.

Wherein, there are colour wheel module different optical filters to pass through for light, and optical filter is vulnerable to the interference of dust, dust Light can be absorbed, so as to cause light transmittance of optical filter to decline, causes DLP projector brightness to decline, therefore, the printing opacity of colour wheel module Rate decides the sustainment rate of light luminance.Therefore need to carry out the optical filter of colour wheel module especially colour wheel module it is dust-proof, with Maintain brightness.And traditional method is merely to seal colour wheel module, and with the position of corresponding optical filter on the housing of colour wheel module Open up and arrange on light inlet and light-emitting window, and the light inlet and the light-emitting window materials such as glass, gone out with this with sealing the light inlet Optical port, but, in the light inlet and the light-emitting window cover glass, brightness can be caused to decline, so as to affect drop shadow effect.
