Description
Technical Field
The utility model relates to a projection equipment technical field specifically is a projection equipment is used in vision transmission.
Background
A projector (also called a projector) is a device that can project images or videos onto a curtain, and can be connected with a computer, a VCD, a DVD, a game machine, a DV, etc. through different interfaces to play corresponding video signals, and is widely used in homes, offices, schools, and entertainment venues. The basic principle of a projector is to enlarge the outline or contour of a workpiece using optical elements and then project it onto a screen. It can be used for profile measurement by transmitted light and for surface shape measurement by reflected light. Besides being used for viewing, projectors are also often used for measurement of complex contours and small workpieces. Lcd (liquid crystal display) liquid crystal projectors may be divided into liquid crystal panel projectors, which are the main products in the projector market, and liquid crystal light valve projectors. The liquid crystal is a substance between liquid and solid, does not emit light, has working properties greatly influenced by temperature, and has the working temperature of-55 ℃ to +77 ℃. The projector utilizes the photoelectric effect of liquid crystal, that is, the arrangement of liquid crystal molecules changes under the action of an electric field to influence the light transmittance or the reflectivity of the liquid crystal unit projector, thereby influencing the optical property of the liquid crystal unit projector and generating images with different gray levels and colors. The LCD projector has good color restoration, the resolution can reach the SXGA standard, the LCD projector has small volume and light weight, and is very convenient to carry, thus being a mainstream product in the market of the projector. According to the number of liquid crystal panels, the LCD projector is divided into three-chip projectors and a single-chip microcomputer, while the single-chip projector has few models, and the most of the single-chip projectors are three-chip projectors. In the projector, there are 3 liquid crystal panels in which liquid crystals are distributed. The liquid crystal is a substance interposed between a liquid and a solid, does not emit light by itself, and is aligned in alignment like pixels on a fluorescent screen. The projector utilizes the photoelectric effect of liquid crystal, namely the arrangement of liquid crystal molecules and the state of the liquid crystal molecules change under the action of an electric field, so that the light transmittance or the reflectivity of a liquid crystal unit is influenced. The projector can achieve the purpose of accurately controlling the light passing through the liquid crystal unit by using an electric signal by using the principle.
The existing projection equipment for visual transmission has the defects that the projector can only fixedly project to one position, the dustproof heat dissipation effect of the projector is poor, and the lens of the projector is easy to damage
