Abstract

The utility model relates to a sound wave remote controlling high-frequency electronic ballast, which comprises an electronic ballast, a power supply circuit, an identifying circuit, a trigger circuit, an output power controlling circuit and a rubber siren. The utility model integrates the electronic ballast and a sound wave remote circuit as a whole, thus the identifying circuit only receives the sound wave transmitted by a sound wave transmitter, and accordingly the purpose that a daylight lamp is switched on or off accurately without directional remote control is achieved. The utility model has the advantages of the functions of sound control and combination with ordinary switches, safety for switching on or off, reliable work and high sensitivity.

Description

Sound wave remote controlling high-frequency electronic ballast

The utility model relates to the ballast of fluorescent lamp, particularly sound wave remote control high-frequency electronic ballast.

At present, the control switch of energy-saving electronic ballast still mechanical basically by, draw, turn round, move the pass.This can not adapt to the requirement that people advance in living standard, and is more inconvenient to old the children and disabled person especially.Existing audio-switch and electric ballast are not one, and received wide frequency range, easily cause misoperation, and the digital program controlled switch of infrared receiving/transmission cost an arm and a leg, and reflector needs power supply, and need directed control.

The purpose of this utility model is that at the deficiencies in the prior art it is one that a kind of current collection sub-ballast and sound wave remote control circuit are provided, and makes identification circuit receive only the pinger emitting sound wave, and is accurate to reach the fluorescent lamp start and stop, do not need directed remote control.

Technical solution of the present utility model in order to achieve the above object realizes in the following way.The utility model comprises electric ballast, power circuit, identification circuit, circuits for triggering, and power output circuit and rubber steam whistle is characterized in that piezoelectric ceramic piece HTD is parallel to BG in the identification circuit ₁Base stage and emitter, inductance coil L ₁With capacitor C ₃After the parallel connection, respectively with this circuit power end and BG ₁Collector electrode link to each other BG ₁Collector electrode link to each other with the trigger end of circuits for triggering.

The utility model does not need power lead, only can be at 10 meters with interior any place start and stop fluorescent lamp, start and stop safety with a rubber steam whistle, reliable operation, highly sensitive, have sound wave controlled function and regular tap and use function, old the children and disabled person and people's daily life at night have been brought very big convenience.

Fig. 1 is an operation principle circuit diagram of the present utility model.

Fig. 2 is a block diagram of the present utility model.

Accompanying drawings most preferred embodiment of the present utility model.The utility model is made up of power circuit 1, identification circuit 2, circuits for triggering 4, power output circuit 5, electric ballast 6 and rubber steam whistle as shown in Figure 1, 2, and piezoelectric ceramic piece HTD is parallel to BG in the identification circuit ₁Base stage and emitter, inductance coil L ₁With capacitor C ₃After the parallel connection, respectively with the power end and the BG of this circuit ₁Collector electrode link to each other BG ₁Collector electrode link to each other with the trigger end of circuits for triggering.

The utility model can adopt the identification circuit shown in 3 among the figure, BG in order further to improve the sensitivity of identification circuit ₁Collector electrode and capacitor C ₄Link to each other capacitor C ₄The other end and switching tube BG ₂Base stage link to each other switching tube BG ₂Collector electrode pass through resistance R ₉Link to each other with the trigger end of circuits for triggering.

In conjunction with Fig. 1 operation principle of the present utility model is described.Civil power is connected after insurance BX passes through C ₁And R ₁After the capacitance-resistance pressure drop by high frequency filter B ₁Eliminate High-frequency Interference, through rectifier diode D ₁～D ₄Carry out full-wave rectification, then by C ₂, R ₂With voltage stabilizing didoe ZD ₁Voltage stabilizing is to 12V, and this voltage is through current-limiting resistance R ₃, be applied to the starting or stopping control circuit of identification circuit and relay, biasing resistor R ₄Be acoustic signals amplifier BG ₁Bias voltage is provided, when acoustic receiver HTD behind the acoustic signals of certain frequency, by BG ₁Amplify, with BG ₁The C that collector electrode links ₃, L ₁Frequency of sound wave is discerned switching tube BG when the frequency range of sound wave is in scope of design ₂The Be Controlled break-make once.Thereby at BG ₂Biasing resistor R ₅High pressure positive pulse of last formation is through resistance R ₉After the current limliting, trigger flip and flop generator 4 upsets.Thereby drive relay J adhesive and release, and realize high-frequency electronic ballast normally-closed contact J ₁Start and stop control.The normally closed contact J of relay ₁After the energized, by rectifier diode D ₉～D ₁₂Carry out full-wave rectification, through C ₉The direct voltage of the nearly 300V of output after the filtering is through R ₁₄To C ₁₀Charging is when voltage reaches bidirectional trigger diode HD ₁During trigger voltage, the diac conducting impels BG ₇Also conducting, pulse transformer B ₂Positive feedback makes BG ₆, BG ₇Square wave oscillation is through L ₄, C ₁₂Series resonance forms approximate sine wave on the filament of lamp tube ends, makes fluorescent light emitting tube.
