But in the tunable optical lamps and lanterns of the prior art, when the dimmer voltage for adjusting brightness is less than 0.7V, then can not
Continue that lamps and lanterns are carried out to adjust to go out, at this point, lamps and lanterns may still be in glimmer state, or is in flashing state, is unfavorable in this way
Lamps and lanterns energy conservation.
Utility model content
Based on the above issues, the utility model provides a kind of energy-saving dimming circuit and lamps and lanterns, can be less than in dimmer voltage
Tune is turned off the light the light adjusting circuit and lamps and lanterns of tool when 0.7V.
To achieve the above object, the utility model provides a kind of energy-saving dimming circuit, including divider resistance and triode mould
Block, the divider resistance are connect with positive polarity, and triode module one end is connect with divider resistance, other end ground connection, institute
Stating the position that triode module is connect with divider resistance is output end.
Further, the triode module includes triode, first resistor and second resistance, described first resistor one end
It being connect with divider resistance, the collector connection of the other end and triode, the base stage of described second resistance one end and triode connects,
Another section of ground connection, the emitter ground connection of the triode.
Further, the divider resistance includes the first divider resistance and the second divider resistance, first divider resistance
It is cascaded with the second divider resistance, the first resistor is in parallel with the second divider resistance.
The triode is NPN type triode.
Originally practical that a kind of energy-saving dimming lamps and lanterns are also disclosed, including energy-saving dimming circuit described in above-mentioned any one, also wrap
Lamp control circuit is included, the control circuit is connect with output end, the base stage of the brightness adjustment control end connecting triode on lamps and lanterns.
The beneficial effects of the utility model are: compared with prior art, the utility model discloses a kind of energy-saving dimming circuit
The light on and off of lamps and lanterns are controlled using the conducting voltage of triode by being provided with triode module with energy-saving dimming lamps and lanterns
System.When the base stage input voltage of triode is greater than 0.7V, the conducting of triode module, first resistor in triode module and the
Two divider resistances are connected in parallel, so that the resistance value of entire divider resistance becomes smaller, the voltage of output end is larger, works as transistor base
When input voltage is less than 0.7V, triode module shutdown, first resistor no current flows through, and the voltage value of output end output at this time is most
It is small.Since lamps and lanterns are connection output ends, when the voltage of output end reaches minimum value, lamps and lanterns can not be lighted, to reach
The purpose turned off the light entirely has saved the power consumption of electric light.
Detailed description of the invention
Fig. 1 is the circuit diagram of the utility model embodiment.
Specific embodiment
In order to more clearly state the utility model, the utility model is further described with reference to the accompanying drawing.
Referring to Fig. 1, the utility model discloses a kind of energy-saving dimming circuit, including divider resistance R2 and triode module
U0, the divider resistance R2 are connect with positive polarity V+, and described one end triode module U0 is connect with divider resistance R2, the other end
Ground connection, the position that the triode module U0 is connect with divider resistance R2 are output terminals A.
It in the present embodiment, is specifically that the triode module U0 includes triode Q1, first resistor R0 and the second electricity
R1 is hindered, the one end the first resistor R0 connect with divider resistance R2, and the other end is connect with the collector C of triode Q1, and described the
Two one end resistance R1 are connect with the base stage B of triode Q1, another section of ground connection, the emitter E ground connection of the triode Q1.Described three
Pole pipe Q1 is NPN type triode, is switched here as one, the base stage B of triode Q1 is controlled by external voltage, according to base
Voltage swing on the B of pole, to control whether on-off and the first resistor R0 of entire triode Q1 have electric current, if Neng Gouyu
Divider resistance R2 connection.
Further, the divider resistance R2 includes the first divider resistance R21 and the second divider resistance R22, and described first
Divider resistance R21 is cascaded with the second divider resistance R22, and the first resistor R0 is connected to output terminals A, when triode module
U0 conducting, when being linked into circuit, can be considered that the first resistor R0 is in parallel with the second divider resistance R22.
In the present embodiment, by being provided with triode module U0, using the conducting voltage of triode Q1 come to the bright of lamps and lanterns
It goes out and is controlled.The base stage B of triode Q1 is connect with regulating circuit, and when the voltage of base stage B is greater than 0.7V, triode Q1 is led
