Abstract

A multifunctional base for energy saving lamps includes a base body defining an inner receiving space and provided with a bottom through hole and a side opening; a circuit board vertically mounted in the receiving space of the base body and having a power conversion circuit provided thereon; and a set of spring conductive strips including at least a first and a second spring conductive strip. The first spring conductive strip has an end electrically connected to the circuit board and another end protruded from the base body via the bottom through hole; and the second spring conductive strip has an end electrically connected to the circuit board and another end protruded from the base body via the side opening. The first and second spring conductive strips act to enable increased contact tightness between the lamp base and a lamp socket.

Claims

1. A multifunctional lamp base, comprising:

a base body internally defining a receiving space, and being provided at a bottom with a through hole and on at least one side of a wall portion with a side opening;

a circuit board being vertically mounted in the receiving space of the base body and having a power conversion circuit provided thereon;

at least one first spring conductive strip having an end electrically connected to the circuit board and another end protruded from the bottom of the base body via the through hole;

at least one second spring conductive strip having an end electrically connected to the circuit board and another end protruded from the base body via the side opening; and

an adjustment mechanism having a link, the link being in the form of a long bar having bends and having a middle pivot shaft, via which the link is movably connected to the circuit board.

2. The multifunctional lamp base as claimed in claim 1, wherein the circuit board has the adjustment mechanism movably connected thereto;

the adjustment mechanism having a first end and a second end, the link being extended between the first and the second end to move the two ends at the same time;

the first end of the adjustment mechanism being pressed against the first spring conductive strip, and the second end of the adjustment mechanism being pressed against the second spring conductive strip.

3. The multifunctional lamp base as claimed in claim 1, wherein the base body is assembled from a first half and a second half, and the receiving space is defined between the first and the second half to have an open top.

4. The multifunctional lamp base as claimed in claim 1, wherein the base body is provided on an outer surface with external screw threads.
