This project originated from studying analog circuits. I originally thought about making a triode constant current source for testing, but then I thought it would be of no use other than testing, so I added a few functions.
It is recommended to use ceramic wicks with a color temperature of 4000K or 2700K. The color temperature of 6500K is a bit cooler, the 4000K color temperature is similar to natural light, and the 2200K color temperature is a little yellow.
Turn the potentiometer to the bottom in the direction of the arrow, and the brightness will be 100 million points. If it feels dazzling, you can adjust the resistance size by increasing R2, R3, R7, R8, and R9 or decreasing R4 and R5.
The multisim14.0 simulation file is attached at the end of the article.
