Description
Technical field
The utility model provides a kind of Special pen for teachers, belongs to the stationery field.
Background technology
Along with developing rapidly of present science and technology, the multimedia application of school is also more and more extensive, because multimedia can give expression to the content that will tell about in the process at school intuitively, most class-teaching of teachers also all be unable to do without multimedia, but multimedia does not see under high light easily, therefore in use need the light of periphery is all covered, will cause like this light in classroom very dark, therefore when some things of record, make mistakes easily, also can cause certain infringement to eyes, simultaneously, present multimedia overhead projector cloth majority all is to hang from the top, classroom, if the teacher thinks that the content of emphasis explanation is in the upper end in telling about process.Teacher then can't clearly tell student knowledge point position, and stands under the projecting apparatus and also can stop light, and content can't be shown.
The utility model content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is: provide a kind of ruddiness that can utilize infrared ray etc. to send to determine rapidly the position of the content of institute's emphasis explanation, and the Special pen for teachers write of the convenient light that in the situation of insufficient light, utilizes the LED fluorescent tube.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Special pen for teachers, comprise a body, it is characterized in that: the top of a body is provided with infrared lamp, this external surface of pen is provided with LED fluorescent tube and operating switch, inside, body upper end is provided with battery compartment, and battery compartment, operating switch, infrared lamp and LED fluorescent tube are connected to form operating circuit after wire connects.Make simple, easy to use.
Described infrared lamp and LED fluorescent tube are connected in parallel by wire.Infrared lamp can not worked simultaneously with the LED fluorescent tube, saves electric weight.
Described operating switch has 3 control shelves.Control respectively infrared lamp and LED fluorescent tube, be conducive to save power.
The beneficial effect that the utility model has is: described Special pen for teachers is controlled respectively the light on and off of infrared lamp and LED lamp by switch, not only can utilize multimedia to give lessons to determine rapidly in the process the teacher position of the content of lecturing, in the insufficient situation of pipeline, can carry out correct writing, described Special pen for teachers, simple in structure, easy to use, be easy to carry, cost is low.
