They are small yellow led pieces attached to a piece of metal referred to as the pcb printed circuit board. This type of printed circuit board is built on top of an aluminum alloy base instead of a fiberglass base. In my case r1 is 470kohm 1 4w r3 is 33ohm 1 4w c1 1uf 400v c2 250v 1uf and after c2 is connect two resistor of 120ohm 1 2w on positive side. Led chips are the components that create the light.
