Be equipped with at present the vehicle of LED steering indicating light, be mostly each steering indicating light and be equipped with fault diagnosis module.When certain steering indicating light et out of order, fault diagnosis module sends breakdown signal to flash module, and flash module changes flash rate, realizes fault flash of light indication.But the problems such as this scheme exists cost high, principle complexity.
Summary of the invention:
The Novel flash device that the technical problems to be solved in the utility model is to provide a kind of LED of being applicable to steering indicating light adopts control chip to replace traditional integrated chip, Gather and input terminal voltage and output end current judge and control the flashing signal of steering indicating light, can judge whether the LED steering indicating light group that power difference is large has steering indicating light to break down.
In order to solve the problems of the technologies described above the Novel flash device that the technical solution of the utility model is a kind of LED of being applicable to steering indicating light, one end connects voltage source, the other end connects steering indicating light group, comprises input sampling circuit, output sample circuit, control chip and flash driving circuit; The input end of input sampling circuit connects voltage source, and mouth connects control chip; The input end of output sample circuit connects the input end of steering indicating light group, and mouth connects control chip; The mouth of control chip connects the input end of flash driving circuit; The mouth of flash driving circuit connects the input end of steering indicating light group.
Preferably, steering indicating light group comprises at least two steering indicating lights.
Preferably, control chip is micro controller system.
The beneficial effects of the utility model are: simple, with low cost, improved accuracy and the reliability of Der Blink und Abblendschalter fault detection, and improved the drive safety of vehicle, be therefore worthy to be popularized and adopt.Adopt control chip to substitute traditional integrated chip, by Gather and input voltage and outgoing current, carry out, after filtering and calculating, judging whether steering indicating light breaks down, realize the function of normal flash of light and the fault flash of light indication of LED steering indicating light.The utility model has solved the problem of the LED steering indicating light fault detection difficulty that power difference is large.
Accompanying drawing explanation
Fig. 1 is the system schematic of the utility model embodiment
In figure:

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
A kind of Novel flash device that is applicable to LED steering indicating light of the present embodiment as shown in Figure 1, one end connects voltage source, and the other end connects steering indicating light group, comprises input sampling circuit 1, output sample circuit 3, control chip 2 and flash driving circuit 4; The input end of input sampling circuit 1 connects voltage source, and mouth connects control chip 2; The input end of output sample circuit 3 connects the input end of steering indicating light group, and mouth connects control chip 2; The mouth of control chip 2 connects the input end of flash driving circuit 4; The mouth of flash driving circuit 4 connects the input end of steering indicating light group.
Steering indicating light group comprises at least two steering indicating lights, and when a steering indicating light breaks down, other steering indicating lights can be realized the function of breakdown signal indication.
The control chip 2 of the present embodiment adopts chip microcontroller.
In described control chip 2, store under the mode of operation of different voltages, the current data of steering indicating light input end, current data when the current data here comprises the current data of the normal work of all steering indicating lights in steering indicating light group and has steering indicating light to break down, input voltage, running current data and the current data while having steering indicating light to break down are corresponding respectively forms different groups.The magnitude of voltage of input sampling circuit 1 Gather and input end exports control chip 2 to, and the current value that output sample circuit 3 gathers mouth is delivered to control chip 2.Control chip 2 can carry out software filtering to collecting magnitude of voltage and current value, and according to the magnitude of voltage now gathering, judgement should compare the current values in gathered current value and which group data, if within the output end current value that gathers drops on the scope of running current data after determining, judge that all steering indicating lights are working properly, if within the current data scope that the output end current value gathering drops on steering indicating light while breaking down, judgement has steering indicating light to break down.
Control chip 2 carries out after above-mentioned judgement obtains a result, at each flash light, all export normal flash rate in normal situation and control signal to flash driving circuit 4, at the fault flash rate that has steering indicating light to break down to export 2 times or 1/2 times normal frequencies, control signal to flash driving circuit 4, flash driving circuit 4 is converted into current signal by flash rate control signal and exports steering indicating light group to.
The present embodiment adopts control chip 2, by Gather and input voltage and outgoing current, judges whether steering indicating light breaks down, and realizes the function of normal flash of light and the fault flash of light indication of LED steering indicating light.What this feature was different from that on existing market, traditional halogen steering indicating light is used can only gather the Der Blink und Abblendschalter that steering indicating light working current judges whether steering indicating light breaks down, and is also different from LED lamp and is equipped with the flash system of fault diagnosis module.
As will be appreciated, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
