Forward voltage drop and light attenuation of LED _ Baidu knows
1, there is no problem with the circuit, so you don't need to consider the resistance of 2K. 2. It is normal that the forward voltage drop drops after 2.LED works for a period of time. This is because the junction temperature of LED chip rises. 3. The light signal is very weak. I didn't know you saw it with the naked eye. ...

The relationship between forward voltage drop of LED and temperature is studied. The physical mechanism of LED forward voltage drop changing with temperature is analyzed, and a constant current driven forward voltage drop coefficient testing system is established. The variation coefficients of LED voltage with different materials and different emission wavelengths are systematically studied experimentally. ...
