Detailed Product Description

The device is now add to teaching content design based on standard experiment schoolbook for obligation teaching course, through experiment, may knowledge synthesis of three primary colors of light.

1.  Structure of principium:

    We select red, green and blue from the device is three primary colors light, display in experience: Three kind of colorful light in red, green and blue, if it is different proportion mix each other, will compare to another three kind of colorful light mix each other are more wide colors of range, and eyesight of person is the most sensitive which light of red, green and blue reaction respectively. Based on all synthesis of colors principium in colorimetry, to three kind of colorful light proceed synthesized. Due to synthesis of colorful light relate to saturation degree of each color light, while two kind of colorful light, if saturation degree is different, its color of synthesis is also different, eg: Synthesize on red-light and green-light, as vary of saturation degree of light, may synthesize orange, yellow and olivine, etc, white color isnt certain value in analysis color chart, such as light of incandescent lamp, natural sunlight and so on. So can only as white color of reference.

The device construction will show in as figure:

1  Light source of primary colors of red, green and bkue.

2  Light screen.

S1Adjust knob in blue light source

S2---Adjust knob in green light source.

S3---Adjust knob in red light source.

3---The power supply switch

2.  Usage methods:

1)  The device install two section of 5# batteries (3V), the device is lay up on level surface table, light screen stand straight in front of light source of primary colors about 200 mm or so.

2)  We start power supply switch and adjust S1, S2 and S3 knob, check light source of primary colors if normal, at the moment, there are facula of three primary colors of red, green and blue in light screen, adequate remove the distance between light source and light screen, make its clear, if facula dont appear to cross primary colors state, may adjust angle of light source, facula appearance will as show in light screen of lift below figure.

3)  Respectively adjust S1 and S2, S2 and S3 and S3 and S1 knob, to observe two beam of synthesis of colorful light situation, it is two primary colors synthesis of light..

4)  Simultaneously adjust S1, S2 and S3 knob, to observe three beam of synthesis of colorful light situation, at the moment, three beam of cross parts of facula is white color as white color of reference. As shown in the picture, that is, synthesis of light of three primary colors.

3.  Attention item:

1)  Dont collided device, in case loss.

2)  The device placed in shady and cool, dry, non- corrosive gas position.
