A portable projector used in home theater

Abstract

The invention discloses a portable projector applied to a home theater, comprising a box body, a hinge and a top cover. The top cover is movably connected to the left side of the top of the box body through the hinge, and the left side of the image imager is on the right side. The middle part of the surface is fixedly connected with a first projection cylinder, one end of the second projection cylinder penetrates the box body and extends to the outside of the box body, and the middle parts of the two sides of the second projection cylinder are fixedly connected with fixing parts, and fixed The surface of the component and the surface of the box body are fixedly connected by bolts, and the invention relates to the technical field of projectors. The portable projector applied to the home theater can significantly improve the lumen of the portable projector when it is used in a strong light place, so that the projected image is clearer and avoids visual blurring. Portable projectors will be more widely applicable and more convenient to use, which is convenient for people to use.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a portable projector used in home theaters. Background technique [0002] A projector, also known as a projector, is a device that can project an image or video onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. Projectors are widely used in homes, offices, schools and entertainment places. According to different working methods, there are different types such as CRT, LCD, DLP, etc. The light sources used by projectors include traditional high-intensity gas discharge light sources (such as ultra-high pressure mercury lamps, Short-arc xenon lamps, metal halide lamps) and new light sources represented by LED light sources and laser light sources. Traditional light source projectors usually make the projected image darker and yellower (such as brightness after a period of use)...

[0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. Projectors are widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP. The light sources used in projectors include traditional high-intensity gas discharge light sources (such as ultra-high pressure mercury lamps, Short-arc xenon lamps, metal halide lamps) and new light sources represented by LED light sources and laser light sources. Traditional light source projectors usually darken and turn yellow as the light emitted by the light source after a period of use. Attenuation, color saturation and contrast reduction, etc.), in applications that require high image quality, even if the bulb is still emitting light, the bulb has to be replaced, so light decay has become an insurmountable problem for projectors using traditional light sources. main obstacle

[0003] When the existing portable projectors used in home theaters are used in strong light places, their lumens will obviously be insufficient, which will cause the projected images to be not clear enough, resulting in blurred vision, and when they are portable, The storage of its curtain is more troublesome, which violates the function of portability, which is not conducive to people's use
