Description
Technical field
The utility model relates to a kind of primaries compound experiment demonstrator, belongs to the teaching aid field.
Background technology
At present, the primaries compound experiment demonstrator that uses in teaching generally is to adopt three spotlights, with projection pattern the light beam of three kinds of colors is thrown to show trichromatic synthetic effect on external screen.Every spotlight is furnished with a power switch and electric light source accordingly, and regular open and close power switch makes power switch fragile; The heat of demonstrator raises when electric light source is opened simultaneously, so the fuselage of demonstrator adopts nonmetallic materials usually; It also is the waste of resource simultaneously that three power switches and electric light source are housed.
The utility model content
1, technical matters to be solved:
In order to solve existing problem in the above-mentioned prior art, the purpose of this utility model provides a kind of primaries compound experiment demonstrator of saving cost, easy to use and long service life.
2, technical scheme
The utility model comprises fuselage, electric light source, power switch, filter glass, support, and fuselage is connected with support, it is characterized in that: body upper is provided with the heat radiation window, and the fuselage interior rear side is equipped with the heat radiation exhaust fan, and afterbody is equipped with two power supply skewer holes; Positive face and and arranged on left and right sides at fuselage head are provided with skewer sheet frame, place filter glass in the skewer sheet frame; The fuselage left and right sides is respectively equipped with the reflective mirror lid, and reflective mirror is equipped with in reflective mirror lid inboard; Reflective mirror lid flexibly connects with the rotatable 180 ° of formulas of fuselage, and reflective mirror covers time-out and can be respectively the filter glass of the left and right sides be hidden.
3, beneficial effect
Because the utility model is equipped with the Switching Power Supply switch that reflective mirror needn't be repeatedly, and fuselage adopts metal material, so be difficult for infringement power switch and fuselage, increased serviceable life of the present utility model; Because the utility model only is equipped with a power switch and electric light source, so saved resource; Because the utility model body upper is provided with the heat radiation window, the fuselage interior rear side is equipped with the heat radiation exhaust fan, heat dispersion of the present utility model is improved, thereby also increased its serviceable life.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is a rear view of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Fig. 1,1 fuselage wherein, 2 is the skewer hole, and 3 is filter glass, and 4 is support, and 5 is reflective mirror, and 6 is skewer sheet frame, and 7 are the heat radiation window, and 9 cover for reflective mirror.
Fig. 2, wherein 8 are the heat radiation exhaust fan.
Using method
With the skewer bar load onto fuselage 1 again skewer install on the tripod, refer to tightly with finger sieve silk at suitable height.Upright 1 open paper size screen, blank sheet of paper, white board all can in vain before the fuselage.Best at a distance of front fuselage 100-150mm, vertical fixing is good.Skewer is gone into green filter glass 3 in the skewer sheet frame 6 before fuselage, about red, the blue filter sheet 3 of each skewer.The 12V power supply connected the skewer head is shared out bonus, black skewer is gone into fuselage skewer hole 2, again the wiring fork is connected 12V shelves on 0-24V student's power supply, 0 grade respectively.The power-on switch, left and right sides reflective mirror lid 9 is opened in the work of this machine, allows red, green, blue three coloured light be radiated at Bai Pingshang side by side.Mobile left side red reflector makes itself and green light overlapping, and then synthesizing yellow moves right and the overlapping then synthetic purple of blue light again.Return red light reflective mirror to green light and cross the center slightly, move the right blue light reflective mirror again and make blueness, green light overlapping, then synthetic cyan.Make blue and green, red overlappingly being moved to the left blue optical screen, what synthesized will be white optical screen.The synthetic experiment of red, green, blue three coloured light this moment produces effect very much.On the white screen of this moment be respectively from left to right: red, yellow, white, blue or green, blue five kinds of colors, upper end are the red purples that synthesizes with indigo plant, and the three primary colors red, green, blue of white light has obtained the effect of testing at this moment.
Though the utility model with preferred embodiment openly as above; but they are not to be used for limiting the utility model; anyly be familiar with this skill person; in the spirit and scope that do not break away from the utility model; can do various variations or retouching from working as, what therefore protection domain of the present utility model should be defined with the application's claim protection domain is as the criterion.
