- The choice of switching error, with indicator light (excluding fluorescent) switch is not suitable to control like small power LED energy saving lamp load, because the load current through the indicator light through to the small power is not already small. A resistor of several hundred K in parallel with the ends of the load can be improved, or the indicator light can be changed directly, and the indicating lamp for canceling the switch can also be improved.
- Q:Home LED lighting downlight is broken, want to change themselves, I would like to ask how to remove ah? Where do you start?
