Abstract
The utility model relates to a power-compensating circuit of a signal light of a vehicle, which comprises a signal light. The power-compensating circuit of a signal light of a vehicle is characterized in that the signal light and a resistor R6 are connected in series between a positive pole of an electric source and a collector electrode of a transistor Q1; a resistor R1, resistor R2, a resistor R3, a resistor R4 and a resistor R5 are connected in parallel between a positive pole of the electric source and a base electrode of the transistor Q1; an emitter electrode of the transistor Q1 is connected to the ground. The power-compensating circuit of a signal light of a vehicle has the advantage that the power-compensating circuit of a signal light of a vehicle provides power compensation for a signal lamp for a vehicle of small volume, small power and low temperature to ensure the normal operation of a power self-examination electronic system inside an automobile; the power-compensating circuit of a signal light of a vehicle has reliable performance and simple structure.
Description
Technical field
The utility model relates to the power compensating circuit of the correlative technology field of automobile-used tally circuit, particularly a kind of automobile-used signal lamp.
Background technology
The automobile-used turn signal lamp that uses generally adopts the halogen bulb of 21W as light source at present.Be subjected to limit value in the lamp body space, when conflicting with temperature conditions, just must use volume, power littler, bulb or light-emitting diode that cal val is lower replace.But when the power that detects signal optical source when vehicle-mounted power detecting system is lower than a certain limit value, will send alerting signal, make chaufeur can't judge the state of current demand signal lamp, cause traffic accident easily.So guaranteeing automobile-used turn signal lamp is problem demanding prompt solution in the power detecting system normal operation that substitutes with low-power light source and don't influence in the automobile.
Summary of the invention
The purpose of this utility model has provided a kind of power compensating circuit of automobile-used signal lamp, solved in the lamp body space and be subjected to limit value, when conflicting with temperature conditions, just must use volume, power littler, under the occasion that bulb that cal val is lower or light-emitting diode replace, when the power that vehicle-mounted power detecting system detects signal optical source is lower than a certain limit value, will send alerting signal, make chaufeur can't judge the state of current demand signal lamp, cause the problem of traffic accident easily.The utility model designs a kind of power compensating circuit of automobile-used signal lamp, comprise signal lamp, it is characterized in that: signal lamp and resistance R 6 are series between the collecting electrode of positive source and aerotron Q1, resistance R 1, R2, R3, R4, R5 are parallel between the base stage of positive source and aerotron Q1, the grounded emitter of aerotron Q1.The utility model has the advantages that the signalling light for vehicle little to volume, that power is little, temperature is low provides power back-off, thereby guarantee the normal operation of automotive interior power self check electronic system, dependable performance, simple in structure.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated,
The specific embodiment
Comprise signal lamp 1 (halogen bulb or light-emitting diode) among the figure, it is characterized in that: signal lamp 1 and resistance R 6 are series between the collecting electrode of positive source and aerotron Q1, resistance R 1, R2, R3, R4, R5 are parallel between the base stage of positive source and aerotron Q1, the grounded emitter of aerotron Q1.Improved the power consumption of signal lamp 1 by this circuit, to reach and the identical power of standard halogen 21W bulb.And when signal lamp 1 (halogen bulb or light-emitting diode) was opened a way, the amplified current that reaches originally disappeared simultaneously to satisfy the needs of flasher power detection electronic warning system.
Claims (1)
1, the power compensating circuit of automobile-used signal lamp, comprise signal lamp, it is characterized in that: signal lamp and resistance R 6 are series between the collecting electrode of positive source and aerotron Q1, and resistance R 1, R2, R3, R4, R5 are parallel between the base stage of positive source and aerotron Q1, the grounded emitter of aerotron Q1.
