Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0033] see Figure 1-7, an embodiment provided by the present invention: a single-chip LCD projector for teaching, including a projector housing 1, and an organic housing vent 2 is arranged on the projector housing 1, so that the temperature inside the projector housing 1 It can be discharged outward through the vent 2 of the casing, which greatly reduces the problem that the temperature inside the projector casing 1 is too high during the working process of the projector and affects normal use. The inner wall of the projector casing 1 is provided with a radiator 3. Through the radiator 3, the air in the projector housing 1 can be well cooled to reduce the temperatur...

Abstract

The invention discloses a single chip LCD projection machine used for teaching. The single chip LCD projection machine comprises a projection machine shell, machine shell ventilation openings are arranged in the projection machine shell, radiators are arranged on the inner wall of the projection machine shell, an internal component protection shell is arranged in the projection machine shell, an LED light source is arranged in the internal component protection shell, a light-condensing lens is arranged on one side of the LED light source, an illuminating system reflecting mirror is arranged onthe other side of the light-condensing lens, a collimating lens is arranged on one side of the illuminating system reflecting mirror, an transmission-type LCD light valve is arranged on the other side of the collimating lens, a field lens is arranged on the other side of the transmission-type LCD light valve, an imaging system reflecting mirror is arranged on the other side of the field lens, a projection lens is arranged on one side of the imaging system reflecting mirror, and rectangular cooling fins are arranged on two sides of the LED light source and the projection lens. For the single chip LCD projection machine used for teaching, the long-axis mirror image reflection and the radiators are arranged, so that the operational performance of the projection machine is more excellent.

Description

technical field [0001] The invention relates to the technical field of LCD projector equipment, in particular to a single-chip LCD projector for teaching. Background technique [0002] With the development of science and technology in China, projectors began to diversify gradually. At present, single-chip LCD projectors use a transmissive full-color liquid crystal display (LCD) as the light valve, usually based on the Kohler lighting system, which focuses the light source image near the entrance pupil of the lens, and the lens forms the image of the light valve on the screen. superior. Since the light source of the Kohler lighting system does not image on the light valve, the local brightness spots of the light source will not be reflected on the light valve during illumination, and will not be reflected on the projection screen, so a smoother image without local lighting spots can be obtained illumination. The basic optical structure of modern single LCD projectors is si...
