I bought a "Rope Light" made for holidays, in an after xmas sale, which was 75% off. I couldn't beat the price. It's a string of white LEDS. I always leave a light on at night, so I thought I'd just use this a night light to save on electric.
It works, but there is a noticable flicker, which is kind of annoying. When I look inside the "rope", a plastic hose, I can see resistors and the LEDs. Thats all. I dont know if these are wired in series, or if each LED is separately connected to the 120V AC power line. There is no "box" on the end, where there would be a circuit board. So, it appears this is running the AC power directly to the LEDs. (I thought they had to run from DC???)
I'm thinking a capacitor should be used to stop the flicker (AC ripple), but there's no way to really add one without ripping the whole thing apart, so I'll just have to live with it.
However, I am curious how this is wired to the AC line. Does anyone know? (Maybe there are some diodes in there, it's hard to actually see the components, but what look like resistors may be diodes, or both).
