Light intensity

[Ambrose1464]

Where can I find an example about control the LED light intensity using LabVIEW? I found in LabVIEW example does not what I want. I need to research this topic before i start my project. Thank you.

Hi,

How are you planning to measure the intensity of the light emitted by the LED?

Do have any camera to measure the light intensity?

It will be good if you can explain your problem and your setup more.

If you are asking about controlling LED light intensity, what light you are having ? What controller you have?

Ist my plan is use my PC interface with LED driver through USB8452 to control the LED light intensity. 

What does you mean the camera to measure the light intensity?

Thank you.

USB8452. I gonna use the LED driver through the USB8452 to control the LED light intensity. The USB8452 have the I2C protocol is it?

-According to product overview it does: https://www.ni.com/en-us/shop/model/usb-8452.html

-Go through this manual : https://www.ni.com/docs/en-US/bundle/ni-845x-hw-dsw-getting-started/resource/371746e.pdf

-Once i used Light intensity control long back, it is voltage controlled means based on voltage input to the light the intensity varies.

-If in your case also same, then you can do the same by setting different voltages to vary to intensity of LED light.

Mind your share the example vi how does it look like? The 2 following link i have seen before d. Sometime I not sure how to implement on LabVIEW only although i understand the concept.
