Intelligent projector for English teaching

Abstract

The invention relates to the technical field of projection equipment, and discloses an intelligent projector for English teaching. According to the invention, a threaded hole is formed in the position, below a resistance rod, of one side of an outer frame, the threaded hole is connected with a lead screw in a sleeving manner through threads, the projector comprises a shell, and a mercury lamp is fixedly mounted in the middle of one side of an inner cavity of the shell; a power machine is controlled to rotate so as to drive a stroke device to rotate, and due to the fact that the threaded hole and the lead screw are connected in a sleeved mode in a threaded fit mode, the threaded hole can move in the axis direction of the lead screw while the lead screw rotates, and therefore the distance between the display device and the light chamber is changed. The light of the mercury lamp enters the light chamber in a divergent manner and is projected to one side of the display device, so that the intensity of the light projected to one side of the display device is changed by changing the distance between the display device and the light chamber, and the projection brightness can be adjusted by the projector in a relatively simple manner. The complexity of the projector is reduced.

Description

technical field [0001] The invention relates to the technical field of projection equipment, in particular to an intelligent projector for English teaching. Background technique [0002] The projector is a very commonly used display device, which can enlarge and display the content displayed on the small screen on the screen, so that more people can watch it conveniently. It is often used in teaching, conferences, and movie screenings. Projectors can be divided into traditional optical projectors, DLP projectors and 3LCD projectors. Traditional optical projection is the most widely used projector due to its simple structure and low price. It mainly includes LED lights, transparent panels and lenses. Composed of these three main components, the light emitted by the LED is irradiated on the transparent panel to form an image, and the formed image is projected through the mirror and lens. It is currently the most widely used projector. [0003] Although the existing traditiona...

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing intelligent projectors for English teaching proposed in the background technology, the present invention provides an intelligent projector for English teaching, which has the advantage of using mercury lamps to improve the projection brightness, and solves the problem of The imaging brightness of traditional equipment is too low and the projection cannot be seen clearly during the day
