Problems solved by technology

[0002] Camera IRIS, also known as iris, is a mechanical aperture in the camera, and the exposure can be controlled by controlling its size. Among them, projectors have been widely used in schools, theaters, conference rooms, etc., but general projectors are limited by technology. The limitation can only be done in normal mode and energy-saving mode, and its brightness is constant
Unable to meet the user's adjustment needs for brightness
[0003] At the same time, the traditional IRIS only has two states of open and closed, and it has no effect when it is opened, and it can only be used for testing contrast when it is closed, and has no other practical use

Abstract

The invention discloses an iris device continuously adjusting the brightness of a projector. The iris device comprises a plurality of slice-shaped iris lenses which are arranged in an iris installation frame and are parallel, wherein one end of each iris lens is connected with a corresponding first gear, the other end of each iris lens is rotationally connected to the iris installation frame, the first gears are meshed with a rack, one end of the rack is meshed with a second gear which is connected with a motor, the motor drives the second gear to move, the second gear drives the rack to move, the rack drives the first gears to move, and the first gears drive the iris lenses to rotate in the same direction at the same time. By means of the scheme, the iris lenses can integrally move within the range from 0 degree to 90 degrees, and continuous adjusting from brightness to dark of a projector image can be achieved.

Description

technical field [0001] The invention belongs to the field of optics and relates to an iris device (also known as an IRIS device, which is a mechanical device used to control the size of an aperture inside a lens) for continuously adjusting the brightness of a projector. Background technique [0002] Camera IRIS, also known as iris, is a mechanical aperture in the camera, and the exposure can be controlled by controlling its size. Among them, projectors have been widely used in schools, theaters, conference rooms, etc., but general projectors are limited by technology. The limitation can only be done in normal mode and energy-saving mode, and its brightness is constant. Can not meet the user's adjustment requirements for brightness. [0003] At the same time, the traditional IRIS only has two states of open and closed. When it is open, it has no effect. When it is closed, it can only be used to test the contrast and has no other practical use. Contents of the invention ...
