Three-primary-color science popularization demonstration instrument

Abstract

A three-primary-color science popularization demonstration instrument comprises a rack and a photosensitive controller, a red LED luminescent tube, a green LED luminescent tube and a blue LED luminescent tube are vertically installed at the top end of the rack at intervals through support rods, a tube body of each LED luminescent tube is provided with a brightness adjustment knob, a photosensitive plate is disposed on a lower-part platform of the rack, the middle of the rack is vertically provided with four display screens, and the photosensitive plate is connected with the display screens through the photosensitive controller. When the three-primary-color science popularization demonstration instrument is used, a red primary color, a green primary color and a blue primary color are projected onto the photosensitive plate through the three LED luminescent tubes, the three primary colors are mixed on the photosensitive plate, and a mixed color and brightness values of the red, green and blue colors are successively displayed through the four display screens. So a dynamic demonstration of a light color change generated by mixing of the three primary colors can be dynamically and visually performed, and a teaching effect is good.

Description

technical field [0001] The invention relates to a three-primary-color science popularization demonstration instrument. Background technique [0002] The three primary colors of light refer to the three colors of red, green, and blue, and the corresponding wavelengths are 700 microns, 546.1 microns, and 435.8 microns respectively. The three primary colors of light and the three primary colors of objects are different. The three primary colors of light can be mixed in a certain proportion to present various light colors. According to the research results of Thomas Young et al., these three primary colors are determined as red, green and blue. All kinds of light colors in nature are produced by mixing these three primary colors. At present, in the field of education and science popularization, the degradation of these three basic colors is generally demonstrated by pictures or slides. Educators cannot dynamically experience the changes in light and color produced by the mixin...

Problems solved by technology

At present, in the field of education and science popularization, the degradation of these three basic colors is generally demonstrated by pictures or slides. Educators cannot dynamically experience the changes in light and color produced by the mixing of the three basic colors, which affects the teaching effect.
