The different color that various objects are shown in nature is mixed by proper proportion by red, green and blue light
Come and is presented in human eye.Therefore, red, green and blue are exactly to form the basis of various colors, referred to as three primary colors
Or three primary colours.The spectral wavelength of three primary colours is as follows：The range category red range of red 700nm, wavelength about 600nm~700nm；It is green
The range category green range of color 546.1nm, wavelength about 500nm~600nm；Blue 435.8nm, wavelength about 400nm~500nm's
Range category blue light range；The light wave of these three colors respectively accounts for one third in visible light.
As shown in Figure 1,5 be the power supply of RGB light-source system；
Standard halogen tungsten lamp：The shape of fiber spectrometer output spectrum is calibrated using the standard sources of the known colour temperature, i.e.,
Relative intensity is calibrated, and user is made to understand the intensity ratio between output spectrum.
RGB light-source system：Traditional three primary light source is to add redgreenblue optical filter to obtain using standard white light light source
It arrives, the spectral characteristic of light source is ensured by filter, and the optical element needed in experiment is more, causes experiment light path more complex, no

The visible light of uniform standard, as the reference light of subsequent detection, with optical fiber by the light-emitting window and fiber spectrometer of integrating sphere
It connecting, fiber spectrometer analyzes spectral component, and fiber spectrometer is connected to computer using USB data line acquires number, from
And obtain the wavelength and relative light intensity of spectrum.
Second step：Operation interface, [+] button on click tools column pop up the interface of newly-built test, click【It is relatively strong
Degree measures】Button.After adjustment suitable parameters (time of integration 400ms), the colour temperature of standard lamp is inputted at colour temperature, is then clicked
【It preserves】Reference spectra is preserved, is clicked【In next step】, obstruct the light, click【It preserves】Half-light spectrum is preserved, is clicked【It completes】, at this time
It changes standard lamp into light source to be measured, relative radiation measurement can be carried out.
Third walks：Then three-color LED light source is put into integrating sphere light inlet instead of standard halogen tungsten lamp, opens LED light source
General supply, the output current by changing each LED light keep the luminous intensity of light source different, just by the watch window of integrating sphere
It can be seen that different color effects, while it can be seen that color effect, is compared by the two and can be found that in operation interface
The practical difference with theory.To pinpoint the problems to student's creation, proposition problem, the chance solved the problems, such as.
Experiment effect can be more intuitively presented to student by the present invention, the color seen by integrating sphere watch window with
The color shown on horseshoe shape and color ordinate in operation interface is compared, and color reality and theory can be understood by being student
Gap and three primary colours ratio synthesis.
