Hallo,
I’m working on a project about intelligent lighting. A short introduction: a lamp that monitor itself and ask for help is something goes wrong and will pay the service invoice with blockchain technology.
I’ve a question about the parameters a LED-driver can provide.
Information on the internet tells me that a LED intensity decrease over time. So, L70 at 50.000 hours means that 70 percent of the initial light is emit around 50.000 working hours. 30 Percent is disappeared, but that 30 percent of light energy can’t be gone. Is that 30 percent convert to heat? Is the forward voltage value changed?
So, can the voltage over the LED, current through the LED or junction temperature of the LED tell me something about the decreasing light intensity?
Thank you in advance.
Bram
