Description

Mixing tester for three primary colors light}

The present invention relates to a three primary color light mixing experiment apparatus, and more particularly, to a three primary color light mixing experiment apparatus for directly experiencing and learning the mixing between these colors by emitting three primary colors together or selectively.

Understanding the mixing of the three primary colors of light is important in the study of colors such as physics and art, and on the other hand, it also plays a very important role in understanding display principles such as CRT and liquid crystal display for television. In order to deepen the understanding of these physical phenomena, it is very effective not only to explain the basic theory but also to experimentally represent such phenomena.

In order to learn the above phenomenon, elementary, middle and high schools and universities are experimenting that light of various colors is formed based on the three primary colors of red, green, and blue while overlapping each other or changing the intensity of different colors.

For example, three primary colors of red, blue, and green cellophane are installed in front of three flashlights and slide projectors, and the three primary colors of light passing through the cellophane are projected on a white screen mounted on a wall. By superimposing a part of the projection image, a result of mixing three primary colors of light is obtained.

However, the color of cellophane paper used in the conventional experimental apparatus is not only technically difficult to produce a color that exactly matches the three primary colors, but it is practically impossible to adjust the color mixing ratio by adjusting the concentration of each color light.

As a result, it is very difficult to obtain perfect white in the overlapping region of the three primary colors of light. Therefore, it is difficult for a learner to perform accurate experiments, and thus it is difficult to obtain a faithful learning effect. In addition, since it was impossible to control the mixing ratio of the three primary colors of light, there was a problem in widening the variety of experiments.

In addition, in case of using a conventional experimental apparatus, the experiment must be conducted in a dark room or in a dark environment, and thus there are limitations in the experimental place. It took a lot of time and effort to prepare for this experiment.

In order to solve the above problems, the registered utility model No. 374000 is manufactured as a portable portable type, and an experimental apparatus has been provided with a control switch which is disposed on a translucent part composed of a semi-transparent body, and which has three primary color light emitters. have. This experimental device is not limited to the experiment site, and the brightness of each illuminator is adjusted by controlling each control switch to show various mixing ratios.

By the way, since the experimental apparatus is expressed only for one color at a time through a single light transmitting body, it was impossible to identify the colors mixed with the three primary colors at once. Therefore, it was difficult to compare and learn about mixing of various colors, and in order to enable this, several experiment apparatuses had to be provided, and each experiment apparatus had to be operated manually.

In order to solve the above problems, the present invention has a purpose to provide a three primary color light mixing experiment apparatus that can grasp the mixing results of the three primary colors of light at a time through a single operation in a single device.
