The CIE x and y values, also known as chromaticity coordinates, are derived from the tristimulus values X , Y , and Z and are used to represent colors on the CIE chromaticity diagram. The factors affecting these values and the equations to calculate them are: Factors Affecting CIEx and CIEy Values 1. Spectral Distribution of the Light Source: The distribution of light across different wavelengths influences the X , Y , and Z values, and consequently the chromaticity coordinates. 2. Color Matching Functions: The CIE color matching functions (usually CIE 1931 XYZ functions) are used to convert the spectral data into tristimulus values. Variations in these functions affect the calculated x and y values. 3. Observer Conditions: The standard observer conditions (e.g., 1931 2° or 10° field of view) used in the calculation of the color matching functions can affect the results. 4. Illuminant Conditions: The type of illuminant used during the measurement affects the spectral data and, subsequently, the chromaticity coordinates.
Yes, it’s possible to find the correct emission values corresponding to the points plotted on a CIE diagram. The CIE diagram is a graphical representation of color based on the three primary color stimuli: red, green, and blue.
hellow Sir, thank u so much for this video. i am looking for this application since from last years but nobody helps me. thank you so so much. it will solve many problems of mine, But sir, from the software source link i can't download the set up file. every time display shows some error. plz help me sir. it's my humble request to you. looking forward to yr kind attention
Glad that you liked it. The same question is asked by many people and I don’t have answer for it. You may try to contact the company. Please share, like and subscribe, thank you.
Hi, thank you for the comment. I have chosen free format to input my PL data. If you follow all the steps then you must be able to find the 380 nm-780 nm option. Hope it will work for you, for further details pleas write an email and its paid service.
Hi, Thank you for reaching out. I don't have very clear answer for your question but when I googled it, I could see some related discussions on the Researchgate....please go through it and good luck.
The same question has been asked by others. I was able download it back in 2022, but now it’s not working. Although, I have a copy but it will be against the company policy. Therefore, please get in contact with company.
@@PhDzzz66 i want to ask that'l how can i use this software for chromacitity by using the uv/vis absorbance or reflecting data to draw the chromacitity
Sir, Today you give lecture at Anand niketan college, warora, I was present there. It was very nice sir

Sir, What parameters affect the CIEx and CIEy values and what are the equations for calculating CIEx and CIEy values separately?
The CIE x and y values, also known as chromaticity coordinates, are derived from the tristimulus values X , Y , and Z and are used to represent colors on the CIE chromaticity diagram. The factors affecting these values and the equations to calculate them are:

Is it possible to find the correct emission value corresponding to the points we plotted in cie diagram
Yes, it’s possible to find the correct emission values corresponding to the points plotted on a CIE diagram. The CIE diagram is a graphical representation of color based on the three primary color stimuli: red, green, and blue.
Hi , Can I draw chromaticity diagram , if I have L*,a* and b* coordinates?

Thank you for your video and I have a question.
I couldn't find 380nm-780nm option so I want to know how to change the spectrum of wavelengths.

How can I plot multiple points in a single CIE diagram using this software?
I have done it in the past. Please look up the details in the software
Dear Sir, the particular site link didnt get connected. Can you provide any other link.
Sorry, company has restricted the software. There is no alternative link for this software.
Can you explain how to find correlated color temperature (CCT)and color purity
Hi, Thank you for reaching out. I don't have very clear answer for your question but when I googled it, I could see some related discussions on the Researchgate....please go through it and good luck.
Sir can you explain how to plot the cie chromatocity in the origin using ascii file
I have tried but was not easy for me to use OriginLab…thick about using matlab or Python
@@PhDzzz66 sir can you share me the link for cie program
Hello sir website you shared is not working please share the setup
Hi, if the website is not working then please search the name of the software in Google and it will direct you to the website.
How can I convert spectra to L*, a*, b*. Thanks
hello sir
will you please share CIE setup i need this app to draw graphs.
Glad that this short video helped you. Here is the link: www.osram.us/cb/tools-and-resources/applications/led-colorcalculator/index.jsp
I can't download the software from website can you please help
Recently I have also faced the same problem. I don’t know why it can’t be downloaded.
unable to download the application from its official website. can you help?

Can we draw the spectra by uv/vis data?
Hi, thank you for your comment. I did not get your question. Could be please elaborate?
@@PhDzzz66 i want to ask that'l how can i use this software for chromacitity by using the uv/vis absorbance or reflecting data to draw the chromacitity
Sorry to say but I am not sure about that. I have used photo luminescence spectra to draw CIE plot as demonstrated in the video.
i am unable to download this app can u assist me
Recently I have also faced the same problem. I don’t know why it can’t be downloaded.
Does somone now how i can download from their page?
Same problem for months... Can't download it from there website
