Series capacitor ?

[Hero999]

I suppose doesn't mean it will stand up in court either.

This is the sort of patent I would gladly ignore and risk someone trying to sue me.

I wonder what the US patent office is doing.

With 20% turnover/yr I guess they are abusing their patent examiners. I lasted three years until I got a boss straight out of a Dilbert cartoon.

Did I mention that capacitive reactance is at right angles to the resistance of the LEDs?

The patented night light has ordinary LEDs with different colours in series. They do not separately fade and brighten each colour with an IC like the rainbow LEDs.

I'm trying to do something related to this topic.

I want to do something similar to this with a maximum of about 50 LEDs. I'm hoping to get about 168 lumens.

Circuit - AC Powered White LED Strings

I'm thinking to use water white LEDs 4000MCD and 60 degrees.

Approximate luminous flux: 3.367 lumens each LED.

4volts at 30 ma is 0.12w. 50X = 6 watts.

Lumens efficiency is 3.367 / 0.12 = 28 lumens/watt = 168 total lumens

I also found something similar.

My question is does this type of circuit work with dimmers such as:
