LED light bulb

[senderj]

I bought a LED light bulb, unfamous brand because of the low price. But I found that there is no transformer in it. The 220VAC direct connect to a full bridge, then to some RC filter and then direct to the LEDs. I don't know if this is a safe design. However, I found that even some famous brand such as Philips or Panasonic, their LED light bulbs are of the same size as mine, which I think is too small to house a transformer. Should I continue to use it?

There is no full transformer or galvanic separation in any LED or CFL light bulbs, but there should of course be some kind of mechanical protection against touching live parts.
If your bulb (or its box) has the relevant safety mark(s) for your country (CE, UL, BS, VDE etc), then there is no reason to stop using it.

Thanks for the reply. I'll give it a try and see what happen.
