SUMMARY OF THE INVENTION 
The primary objective of the present invention is to provide a stabilizer 
which includes means for adjusting the light of the lamps. 
In accordance with one aspect of the invention, there is provided a 
stabilizer circuit comprising a power switch, a lamp, a double 
stabilization device including first active terminals and second active 
terminals, the first and second active terminals being consecutively 
activated when the power switch is turned on and off one time, a relay 
including a coil connected to one of the active terminals of the double 
stabilization device, and two connected to the lamp and coupled to the 
coil of the delay, the means including two different values for adjusting 
output values of the lamp so as to adjust the lightness of the lamp. 
The two means may be two inductors coupled together in series and having 
different inductance and coupled to the coil of the relay, the relay 
includes a first terminal connected to a position between the inductors, 
and a second terminal connected to an end portion of the inductors. 
The two means may be two capacitors coupled together in parallel with each 
other and having different capacitance, and the relay includes a terminal 
connected between the capacitors. 
Further objectives and advantages of the present invention will become 
apparent from a careful reading of the detailed description provided 
hereinbelow, with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to the drawings, and initially to FIG. 3, a stabilizer circuit in 
accordance with the present invention comprises a typical circuit 20 
having a lamp 12 and a switch 301 provided therein, and the improvement 
comprises an adjusting circuit 30 which includes a transformer 31 for 
generating DC current and a pulse to a double stabilization device 32 
which includes two active terminals, the active terminals will be 
alternated when the double stabilization device 32 receives the pulse from 
the transformer 31, a relay 33 includes a coil 330 connected to the double 
stabilization device 32 and includes two terminals 331, 332, the first 
active terminals of the double stabilization device 32 are connected to 
the coil 330 of the relay 33, two inductors 34, 35 in which the first 
inductor 34 has a greater inductance value than that of the second 
inductor 35, the first inductor 34 is connected to the second terminal 332 
and the second inductor 35 is connected to the first terminal 331. 
In operation, when the switch 301 is turned on, the transformer 31 
generates and provides a DC current and a pulse to the double 
stabilization device 32 so as to actuate the first active terminals of the 
double stabilization device 32, at this moment, the coil 330 is connected 
to the double stabilization device 32 such that the second terminal 332 is 
turned off and the first terminal 331 is turned on, and such that the 
inductor 35 is actuated, because the inductor 35 has a greater inductance 
value, the frequency of the circuit will be decreased and the output will 
also be decreased, whereby, the light of the lamp is decreased. 
When the switch 301 is turned off and turned on again, the other active 
terminals of the double stabilization device 32 are actuated or turned on 
such that the coil 330 is not energized and such that the second terminal 
332 of the relay 33 is connected and the first terminal 331 is turned off, 
at this moment, the inductor 34 is actuated such that the frequency is 
increased and the light of the lamp is also increased. 
Referring next to FIG. 4, illustrated is another type of the stabilizer 
circuit, in which the coil 330 of the relay 33 is connected to one of the 
active terminals of the double stabilization device 32 similar to that 
shown in FIG. 3, the lamp 12 is connected to a capacitor 36, another 
capacitor 360 is disposed in parallel to the capacitor 36, and a switch 
331 of a relay is connected between the capacitors 36, 360. 
In operation, when the power switch is turned on and when the double 
stabilization device 32 is not connected to the active terminal of the 
coil 330 of the relay 33, only the capacitor 36 is actuated such that the 
capacitance of the circuit is low and the lamp 12 has lower lightness. 
When the power switch is turned off and turned on again, the double 
stabilization device 32 is connected to the active terminal of the coil 
330 of the relay 33 such that the coil 330 is energized, at this moment, 
both of the capacitors 36, 360 are coupled together and actuated such that 
the capacitance of the circuit is increased and the lamp 12 has an 
increased lightness. 
Accordingly, the light or the lightness of the lamp can be easily changed 
by the stabilizer circuit in accordance with the present invention. 
Although this invention has been described with a certain degree of 
particularity, it is to be understood that the present disclosure has been 
made by way of example only and that numerous changes the detailed 
construction and the combination and arrangement of parts may be resorted 
to without departing from the spirit and scope of the invention as 
hereinafter claimed.
