Problems solved by technology

[0002] Most colors can be produced by synthesizing three colors of red, green and blue according to different proportions. At present, there is no physical demonstration experimental device to demonstrate the color mixing process of adding or subtracting these three colors according to different proportions; this paper The technical problem to be solved by the invention is to provide a color demonstration method and its experimental device with simple structure, convenient operation and vivid image for the deficiencies of the prior art

Embodiment 1

[0009] Example 1. Illuminate the red LED light, green LED light, and blue LED light on the same area of ​​the standard whiteboard, adjust the potentiometers corresponding to the red LED light, green LED light, and blue LED light respectively, and you can see the light on the standard whiteboard The color of is changing.

Embodiment 2

[0010] Example 2. Illuminate the red LED light, green LED light and blue LED light on the same area of ​​the standard whiteboard, place the demo pattern in front of the blue LED light, you can see that the color of the pattern on the standard whiteboard is yellow, and the background color is white , respectively adjust the potentiometers corresponding to the red LED light, green LED light, and blue LED light. You can see that the color of the graphics on the standard whiteboard is changing, and the background color is also changing.

Embodiment 3

[0011] Example 3. Illuminate the red LED light, green LED light, and blue LED light on the same area of ​​the standard whiteboard, and place the demonstration pattern in front of the red LED light. You can see that the color of the pattern on the standard whiteboard is cyan, and the background color is white. Adjust the potentiometers corresponding to the red LED light, green LED light, and blue LED light respectively, and you can see that the color of the demonstration pattern on the standard whiteboard is changing, and the background color is also changing.

Abstract

The invention relates to a color demonstration method and experiment apparatus. The color demonstration method and experiment apparatus is characterized by consisting of a power supply, a lead wire, potentiometers, a red LED lamp, a green LED lamp, a blue LED lamp, a demonstration pattern and a standard white plate. Colors of light of the red LED lamp, the green LED lamp and the blue LED lamp are taken as three primary colors, the demonstration pattern is placed in front of the corresponding LED lamp, the light is irradiated on the standard white plate, through adjusting the potentiometers, the proportions of red, green and blue light irradiated on the standard white plate can be adjusted, and thus the color of the demonstration pattern on the standard white plate and the background color are changed. The color demonstration method and experiment apparatus can serve as a physics demonstration experiment instrument and be applied to popular science education and the like.

Description

technical field [0001] The invention relates to a color demonstration technology, in particular to a color demonstration method and an experimental device thereof. Background technique [0002] Most colors can be produced by synthesizing three colors of red, green and blue according to different proportions. At present, there is no physical demonstration experimental device to demonstrate the color mixing process of adding or subtracting these three colors according to different proportions; this paper The technical problem to be solved by the invention is to provide a color demonstration method and its experimental device with simple structure, convenient operation and vivid image in view of the deficiencies of the prior art. [0003] The technical problem to be solved by the present invention is achieved through the following technical solutions. The invention relates to a color demonstration method and an experimental device thereof, which is characterized in that it is ...
