Description
Technical field
The utility model relates to one kind to recharge decoder, LED lamp of automobile recharges decoder and LED lamp of automobile illumination system
System, belongs to auto alarm technical field.
Background technique
The genuine head lamp of major part automobile still uses halogen tungsten wire H7 lamp for dipped headlight at present, and H7 light bulb is GB15766
The head lamp bulb model of standard has the advantages that technology maturation, cheap, but there are the short problems of service life, now after dress
Entrucking lamp after miscellaneous H7LED has been emerged in large numbers in market, and more car owners select entrucking lamp after H7LED, because it has efficiency
Height, the feature of service life length.
But since the warning system of automobile can detect the power consumption of car light, the entrucking lamp < genuine vehicle after H7LED of replacement
Lamp H7 halogen lamp can make driver's mood irritated, influence safe driving then the alarm system of automobile will report an error always.
Genuine car light H7 halogen lamp=45W, (in the case of automobile is for modulating voltage=13.2V), therefore system can detect head lamp
Power consumption can just show that normally alarm system just not will start within the scope of 40~50W.
But power consumption=27W or so of entrucking lamp after H7LED, well below the 45W of former lamp, therefore the car light alarm of automobile
System can report an error always.
In order to solve the problems, such as that system reports an error, there is a large amount of decoder in existing market, and essentially all of decoder is all adopted
With a kind of mode: resistance-type decoder.
Since resistance-type decoder is to generate the output end of resistor coupled in parallel to car body controller by it by the way of
The power consumption of 18W just maintains an equal level with the 45W of former lamp, as shown in Figure 2 along with the 27W power consumption of entrucking lamp after H7LED.To solve
The problem of certainly automobile alarm system reports an error.But since decoder produces the power consumption of 18W, it will affect the heat dissipation of system, it can
The mechanism being bonded with it can be scalded, if heat dissipation is bad, it is also possible to resistance itself can be caused to burn, or even generated safe hidden
Suffer from, and in practical application, in the case where having installed radiator additional, there are still above situation generations.
Summary of the invention
Technical problem to be solved by the utility model is to provide one kind can solve alarm system report an error, problems of excessive heat
And energy-efficient recharge decoder, LED lamp of automobile decoder and LED lamp of automobile lighting system.
In order to solve the above technical problems, the technical solution adopted by the utility model is:
One kind recharging decoder, is lower than circuit requirement electric current/power consumption requirements for having element current/power consumption in circuit,
The decoder is made of charger circuit, using parallel, is controlled the decoder input current, is made itself and circuit
Middle other elements total current meets the circuit requirement electric current/power consumption, controls the decoder output voltage higher than electricity in circuit
Source voltage recharges electricity remaining in the decoder to the power supply in circuit.
A kind of LED lamp of automobile recharges decoder, requires electricity lower than car body controller for LED light electric current/power consumption in circuit
Stream/power consumption requirements, the decoder are made of charger circuit, using parallel, control the decoder input electricity
Stream, makes it meet the car body controller requirement electric current/power consumption with LED light total current, and it is high to control the decoder output voltage
In automobile battery voltage, electricity remaining in the decoder is recharged to automobile batteries.
The decoder input current and LED light input current total current are equal to car body controller supply current.
The decoder input current is 1.4A.
The decoder output voltage is 14~16V.
A kind of LED lamp of automobile lighting system, including automobile batteries, car body controller, LED light and a kind of such as above-mentioned vapour
Vehicle LED light recharges decoder.
The car body controller supply current is 3.4A, and LED light supply current is 2A, and the decoder input current is
1.4A。
The automobile battery voltage is 12V, and the decoder output voltage is 14~16V.
The utility model is achieved the utility model has the advantages that using decoder is recharged in the present invention, will control electric current residual current
Recharged again through decoder to battery, not only can to avoid various security risks caused by resistance decoder bring problems of excessive heat,
Energy-efficient effect can also be played.
Detailed description of the invention
Fig. 1 is a schematic diagram of the H7 halogen lamp in normal lighting；
Fig. 2 is the schematic diagram of resistance decoder decoding process currently on the market；
Fig. 3 is the schematic diagram that decoder decoding process is recharged in embodiment；
Fig. 4 is the basic schematic diagram that decoder is recharged in embodiment.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
As shown in figure 3, a complete lighting system is by automobile batteries 1, Body Control for filling LED light after automobile
Device 2 recharges the dress composition of headlamp 4 after decoder 3 and H7LED, and car body controller 2, voltage are arrived in the wherein power supply of automobile batteries 1
=12V, there are two functions for car body controller 2, and wherein function is first is that function of supplying power, is responsible for giving the power supply of automobile H7LED dipped beam, night
Dipped beam is lighted, road surface, convenient and safe driving, supply voltage=13.2V or so are illuminated；Function is second is that power consumption detecting and alarm function
Energy.When it detects that the power consumption of low-beam function is beyond setting 40~50W of power consumption, warning function will start, and will not disappear
It loses, will affect the driving mood of driver in this way.Power consumption=27W of dress lamp 4 after H7LED is novel is unable to reach detection setting function
It consumes between 40~50W.This is the power consumption due to combining light distribution requirements and current LED chip to be unable to reach 45W.
The present invention supplies electricity to fill lamp 4 after H7LED is novel while crossing the side for the decoder 3 that supplies electricity to backwash using car body controller 2
Method solves the problems, such as that car body controller is alarmed, and battery backwashes decoder 3 using charger principle, specifically shown in Fig. 4
A kind of charger circuit for (Fig. 4 is only one of circuit structure for realizing of the present invention, can not be used to limit the present invention
Protection scope), battery is limited by resistance R6 and is backwashed input current=1.4A of decoder 3, and is controlled by resistance R13
Output voltage is 14~16V, and 2 supply currents of car body controller=3.4A, supply voltage=13.2V reaches the power consumption of 45W,
Power consumption=27W of dress lamp 4, supply current=2A, remaining 1.4A electric current are returned by the battery formula decoder 3 that backwashes after H7LED is novel
It rushes to automobile batteries 1.The problem of thus can solve car body controller alarm, reaches decoding effect.And using solution in this way
Code mode largest benefit is to recharge power consumption simultaneously in fine control, and the power consumption of decoder consumption itself is very low, can be to system
Heat plays optimization function, guarantees that the temperature inside lamp chamber is not too high, and be attached to plastic shell structure, not will cause plastic cement
The overheat of part, securely and reliably.And by recharging mode, real energy-conserving action can be played.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
