ABSTRACT:
A light-emitting device pressure ring structure includes a mounting base for mounting, a circuit board accommodated in the mounting base and having electrode pins connectable to an external power source, a holder member insertable in the mounting base, a light-emitting unit fixedly mounted in the holder member with a bottom heat sink thereof suspending outside the holder member and tubular electrodes thereof connectable to the electrode pins of the circuit board for power input, and a pressure ring cap detachably threaded onto the mounting base to hold down the holder member and to keep the heat sink of the light-emitting unit outside the mounting base for quick dissipation of waste heat from the light-emitting devices of the light-emitting unit.
