Moreover, the four circuit boards 12' are connected to the setting part 141' on the lamp holder 14' through the insulating base 11'. In addition, several LED assemblies 13' are respectively arranged on the surfaces of four circuit boards 12'; and these LED assemblies 13' are all controlled by a driving control circuit module 15' on the circuit board 12' to emit light.
