Here’s page & description of how LED Christmas lights work. I found this site while searching for a way to repair a string of LED lights. This answered a lot of questions I had, like why the LED lights flicker, and why there is no obvious transformer or voltage converter in the string.
They also have a page on incandescent Christmas lights and how to troubleshoot/repair them.

    I too have the exact same phillips LEDs. The blinking is enough to make me nauseous if it is the only source of light. There is however a solution! The Sylvania LED Micro-Style Lights (purchased from BJs) have some kind of phosphor like effect, when you pull the plug the glow slowly dies over the course of 20-30 seconds. As far as I can tell these lights have no discernible blinking effect.
