LED teaching director for multimedia classroom based on multi-dimensional sensing and system thereof

Abstract

The invention discloses an LED teaching director for a multimedia classroom based on multi-dimensional sensing and a system thereof, and relates to the field of teaching auxiliary equipment. A plurality of uniformly distributed light intensity sensors are embedded into the outer ring side of an irradiation sensing cylinder; a first position distance sensor and a second position distance sensor areembedded into the front side end surface of the irradiation sensing cylinder; an adjusting driving device for driving and adjusting the focusing position of the LED light source is arranged in a first mounting cylinder; a first rear side threaded groove is formed in the rear side of the first mounting cylinder; and a pair of first elastic conducting strips and a signal plug are arranged in the first rear side threaded groove of the first mounting cylinder. According to the invention, a mean sensing detection position distance sensor group is arranged, and a surrounding type light intensity sensor is combined to carry out sensing detection on the light intensity of the surrounding environment, so that the LED light source intensity and focusing adjustment are efficiently and accurately completed in an energy-saving manner, and pointing blackboard-writing teaching or multimedia indication operation is carried out in an LED manner.

Description

technical field [0001] The invention belongs to the field of teaching auxiliary equipment, in particular to a multi-dimensional sensor-based LED teaching pointer for multimedia classrooms and a system thereof. Background technique [0002] In the existing classroom teaching, or in the corresponding explanation process of multimedia content, teachers or explainers sometimes wander around in various positions in the classroom and hall. In order to better cooperate with the explanation, the explainer generally uses a laser pointer to Point to the content to be explained. [0003] However, the concentrated light intensity of the laser pointer is too high. When the operator forgets to turn off the laser pointer when using the laser pointer or placing the laser pointer, and accidentally points to the human body or face, it is very likely to cause damage to a certain part of the human body. [0004] In the structure that replaces the laser pointer pointing, the long-distance light...
