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
The present invention relates to a kind of three primary colours science popularization demonstrator.
Background technology
The three primary colors of light refer to red, green, blue three look, and each self-corresponding wavelength is respectively 700 microns, 546.1 microns, 435.8 microns, and the three primary colors of light and the three primary colors of object are different.The three primary colors of light mix by a certain percentage can present various photochromic.According to the result of study of the people such as Thomas poplar, these three kinds of primary colors are defined as RGB.Natural various photochromic all mixing by these three kinds of primaries produces.At present, in education and science popularization field, the degraded for these three kinds of Essential colour is generally adopt picture or lantern slide to demonstrate, and the photochromic change that the mixing that educatee dynamically cannot realize three kinds of Essential colour produces, affects teaching efficiency.
Summary of the invention
The object of the present invention is to provide a kind of three primary colours science popularization demonstrator, dynamically can carry out dynamic demonstration to mixing by three kinds of Essential colour the photochromic change produced intuitively, teaching efficiency is good.
The object of the present invention is achieved like this, a kind of three primary colours science popularization demonstrator, comprise frame and photosensitive controller, by support bar vertical interval, RGB three LED are installed on the top of frame, the body of LED is arranged respectively brightness regulation knob, the lower platform of frame is arranged one piece of photographic plate, the middle part of frame vertically arranges four pieces of display screens, and photographic plate respectively connected display screen by photosensitive controller.
When the present invention uses, project RGB three kinds of Essential colour by three LED on photographic plate, on photographic plate, three kinds of Essential colour mix, and are shown the brightness number of mixed color and RGB three kinds of colors by four pieces of display screens successively.Thus dynamically can carry out dynamic demonstration to mixing by three kinds of Essential colour the photochromic change produced intuitively, teaching efficiency is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is perspective view of the present invention.
Embodiment
A kind of three primary colours science popularization demonstrator, as shown in Figure 1, comprise frame 3 and photosensitive controller, by support bar vertical interval, RGB three LED 2 are installed on the top of frame 3, the body of LED 2 is arranged respectively brightness regulation knob 1, the lower platform of frame 3 is arranged one piece of photographic plate 5, the middle part of frame vertically arranges four pieces of display screens 4, and photographic plate 5 respectively connected display screen by photosensitive controller.When the present invention uses, on photographic plate, project RGB three kinds of Essential colour by three LED and form three color spots 6, on photographic plate 5, three kinds of Essential colour mix, and are shown the brightness number of mixed color and RGB three kinds of colors by four pieces of display screens 4 successively.
