Abstract

The utility model provides a demonstration instrument for the principle of three primary colors, which is composed of a lamp box for lamps with three primary colors, a hole baffle plate and an optical screen, wherein, the lamp box is provided with three electrical lamps, such as red, green and blue and the hole baffle plate corresponding to the central position of three colors of electrical lamps is provided with a circular through-hole. The baffle plate is arranged between the lamp box and the optical screen and three electrical lamps of the lamp box respectively emits red, green and blue lights on the optical screen through the baffle plate circular hole to present an effective image with three primary colors. The utility model has the advantages of novel structure, clearness and visual ability, convenient operation and easy portability, and is a demonstration instrument for teaching.

Description

The three primary colors principle demonstration instrument

The utility model relates to a kind of demonstration instrument of the usefulness of imparting knowledge to students, the three primary colors principle demonstration instrument that especially a kind of physical optics is used.

In the physical optics teaching, need carry out the demonstration of three primary colors principle usually, and existing three primary colors principle demonstration method adopts mainly three primary colors rotating disks of red, green, blue to rotate demonstration, its effect is relatively poor, and operation inconvenience directly has influence on quality of instruction.

The purpose of the utility model provides a kind of novel structure, good demonstration effect, novel three primary colors principle demonstration instrument easy and simple to handle.

For achieving the above object, the technical solution of the utility model is: adopt the three primary colors principle demonstration instrument of being made up of three primary colors lamp lamp box, hole plate washer and optical screen.Three electric lights that are respectively the red, green, blue look of load in lamp box, three of corresponding lamp box electric lights are shaped on manhole on the plate washer body, and plate washer is placed between lamp box and the optical screen.During demonstration, with the lamp box energized, three electric lights are launched red, green, blue coloured light respectively, and light passes the plate washer circular hole and shines and present the three primary colors design sketch on the optical screen, and can show at optical screen desirable three primary colors effect is shown by adjusting distance between plate washer and lamp box or optical screen and the plate washer.After finishing, plate washer and optical screen can be put in lamp box, easy to carry and store.

Because the utility model is the three primary colors principle demonstration instrument that adopts three primary colors lamp lamp box, hole plate washer and optical screen to form, and need not the darkroom during demonstration, just can demonstrate under the available light condition.It is compared with existing demonstration teaching aid, its novel structure, good demonstration effect, clear and intuitive, easy and simple to handle, be easy to carry about with one, and can improve the quality of teaching, be a kind of novel demonstration instrument for teaching.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the front view of lamp box in the utility model.

Fig. 2 is the front view of the utility model mesopore plate washer.

Fig. 3 is the front view of optical screen in the utility model.

Fig. 4 is a demonstration instance graph of the present utility model.

Fig. 5 is a three primary colors effect diagrammatic sketch on the utility model optical screen.

With reference to accompanying drawing, the utility model is made up of three primary colors lamp lamp box (1), hole plate washer (3) and optical screen (4), on lamp box (1), be shaped on three round holes that are positive angular position with circumference uniform distribution, in three round holes of lamp box, install red, green, blue electric light (2) (see figure 1) respectively, hole plate washer (3) is to be shaped on the manhole (see figure 2) on the plate washer body in three electric light centres of corresponding lamp box, is being positioned at placement hole plate washer (3) (see figure 4) between lamp box (1) and the optical screen (4).

The utility model is the hole mouth place installing anti-dazzling screen of dress electric light in lamp box (1) also, and the anti-dazzling screen by redgreenblue light exit place on the mobile lamp box changes the intensity of three coloured light that radiate and demonstrates out any photochromic effect.
