I bought a light dimmer from IKEA.
If I connect my dimmer switch to a normal bulb and slide the controller from off to on slowly, the light intensity slowly increases from off to full brightness.
If I connect a string of LEDs to the dimmer and do the same sliding from off to on, the bulbs first increase in brightness, then decrease in brightness to almost off, then increase again to full brightness. Why?
I'd appreciate any help you can offer.
Thanks ~Helen
(PS) I did a little research on how dimmer switches work, and they work by turning on the incoming AC signal only when it reaches a certain nonzero threshold, then keeping it on for the rest of the cycle. (The technology is called TRIAC - see
