Basic light viewing instrument for the students' experiment

摘要

The present invention relates to a three-way light synthesis observation device for experiments such as the synthesis of various lights according to the three primary colors of light.;Elementary and junior high school students are experimenting to form various lights based on the three primary colors of red, blue, and yellow as these lights overlap each other or change in intensity of different colors. What is currently used for this experiment is to prepare a halogen lamp in three primary colors by using a halogen lamp and to project it on the screen on the wall using a light projector, the three primary colors are illuminated. In this state, by adjusting the brightness of the three primary colors, the change of light in the overlapping state is observed.;These devices require space to project light once, a screen onto which light is projected, and a strong power source. Therefore, the equipment itself is expensive, there is a disadvantage in that it is inconvenient to use because it requires the generation of high heat, suitable dark maintenance necessary for projection.;The present invention is a simple portable structure to install a light-emitting body such as a low power consumption LED, the upper portion of the inside is a transparent body, the outer surface is disposed a translucent part consisting of a semi-transparent body, each of these three-element light emitting body Adjustable control switch to adjust the brightness of each voltage. Therefore, the three primary colors are expressed on the light-transmitting part by simply connecting the power supply, and the method of expression can be expressed by the operation of the control switch.
