I am converting white LED string lights into over head outdoor lighting. The box says I can connect up to 45 strings. I will only need about 10.
Since they flicker, I made a functional rectifier using 4 x 1N4007 (2 x 2 series and 2 x 2 parallel). During the test, I used a capacitor rated 4.7uF and 400 V. [All 5 components I desoldered from old phone chargers.] All of the lights turn on and stopped flickering.
When I finish, all will be encased in weatherproof housing.
Each full wire (70 LEDS) is 4.8 W and 0.04 A, and each LED is 3.4 V and 0.068 W.
One full string is actually a manufactured two strings of 35. At the end of the full 70 (2 x 35), is a two prong female outlet designed for daisy chain. [With the rectifier, I have to make note of the rectified polarity.]
My home is standard US 120 V.
I know directly rectified DC is more dangerous than the corresponding AC.
Once I create this bridge, how much should I decrease the DC to allow for 10 strings (700 LEDs) and be safe?
Is there a better off the shelf device I could buy?
Can I possibly use an old cell phone charger? Maybe remove some post rectified components to increase the DC to the needed output for 700 LEDs (10 strings x 70 LEDs).
Thank you for your feedback.
