Imaging component for projection system

Abstract

The invention provides an imaging component for a projection system, which comprises an extended camera lens device which can be connected with an image outlet of the body of the projection system viaa rotating mechanism; and by rotating the rotating mechanism, the projection system can alternatively project images onto screens in two directions that are perpendicular to each other by the extended camera lens device, respectively, wherein, the images projected in the two directions perpendicular to each other meet the image ratio of reciprocal.

Description

technical field [0001] The present invention relates to an imaging component, especially an imaging component arranged on a projection system to selectively project images with a proper display ratio. Background technique [0002] With the advancement of information technology, the amount of digital data is increasing rapidly, and digital devices for displaying digital data are also booming. Among them, since the projection system receives digital data input from an external digital device, and projects an enlarged image after processing, the digital data is clearer and easier to see, and it can be used in some situations (such as projecting video games) or movie images) to provide richer entertainment effects, so it has become a display device commonly used in digital devices. [0003] Generally speaking, the display specification of digital data is often set to a specific display size ratio. Specifically, the display ratio of the digital data (that is, the ratio of the h...

Problems solved by technology

But when wanting to project the image pattern of the original display ratio, the user needs to put the projection system back to the horizontal position, which increases the inconvenience of use, and the placement area of ​​this arrangement is small, and the projection system is relatively large. unstable

[0006] On the other hand, changing the placement of the projection system is not only inconvenient to use and causes the projection system to be placed more unstable, but also the lamp inside the projection system has a specific angle of use. Improper rotation of the projection system may cause damage to the wick and shorten the life of the lamp. , but also affect the arrangement of projection system heat dissipation

Specifically, since the heat dissipation components inside the projection system are designed according to the originally set placement of the projection system, and the internal fan has a certain air circulation direction according to the ventilation holes of the projection system casing, the placement of the rotating projection system body may be It will cover the ventilation holes of its casing, affect the effect of forced convection of the fan, and lead to poor heat dissipation performance, so that the internal components of the projection system (especially the bulbs inside the projection system) will not be able to smoothly and effectively discharge a large amount of waste heat. Outside the projection system body, the long-term accumulation of waste heat will cause serious damage to the projection system and affect its service life, so this is not a feasible image adjustment method

[0007] As can be seen from the above, when projecting the image pattern of the existing digital device through the projection system, if the image pattern is to be rotated 90° and then played, the length and width of the image must be proportionally reduced to allow the normal viewing of the projected image at the original display ratio. There is no other effective way to increase to a larger image magnification
