Abstract
The utility model relates to a detection device of an LED steering lamp. The detection device comprises a vehicle body control module and a steering lamp control module connected with the vehicle body control module. The steering lamp control module outputs currents to the LED lamp and drives the LED lamp to light. A storage unit is arranged in the steering lamp control module which is further connected with a temperature sensor disposed in the LED steering lamp. The detection device is characterized in that the temperature sensor is connected with an over-temperature alarm device which is composed of a temperature detection circuit, a comparing control circuit and a trigger control type warning sound alarm circuit. The detection device of the LED steering lamp is not influenced by temperature changes of the LED lamp, is accurate in detection, can give out different prompts according to the damage situation of the LED lamp, provides more choices for a driver, and has high practical value.
Description
Technical field
The utility model relates to a kind of LED steering indicating light detecting device.
Background technology
At present, along with improving and the decline of cost of LED lamp technology, the application of LED lamp on automobile lamp is more and more general, and almost various car lights have the application of LED lamp, also have a lot of flashers to use the LED lamp.The legal provisions flasher must detect constantly, avoids not knowing the steering indicating light damage because of chaufeur and causes driving hidden danger.The detection of conventional bulb steering indicating light is to realize by the break-make of measuring its DC current, and the LED steering indicating light normally series and parallel mix, even there is single led lamp to damage, the electric current of whole steering indicating light can not reduce to zero quickly yet, simultaneously because LED lamp current temperature influence is larger, therefore the words error of utilizing merely electric current to detect is large, is prone to the situation of flase alarm.Most producer is by LED lamp lamp being connected to reduce the difficulty of detection, if but can cause like this a LED lamp to damage the phenomenon that whole steering indicating light can't be used, can't guarantee the safety of travelling, lose the advantage that the series and parallel of LED lamp mixes.In sum, the imperfection of LED steering indicating light detecting device and method has limited the application of LED lamp on steering indicating light.
The utility model content
The purpose of this utility model is for defects, and a kind of LED steering indicating light detecting device accurate, applied range that detects is provided.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of LED steering indicating light detecting device, comprise Body control module 1 and the steering indicating light control module 2 that is connected with Body control module, described steering indicating light control module outputs current to LED lamp 3, the driving LED lamp is luminous, be provided with memory cell 4 in the described steering indicating light control module, the steering indicating light control module also connects the temperature sensor 9 that is arranged on LED steering indicating light inside, it is characterized in that, described temperature sensor connects overtemperature alarm dress, 5, described excess temperature alarm device comprises temperature sensing circuit 6, comparison control circuit 7 and triggers controllable type warning signal sound alarm circuit 8.
Described Body control module also connects a turning indicator 10, and this turning indicator is positioned on the automobile instrument panel 11.
Each LED steering indicating light inside is provided with a plurality of well-distributed temperature sensors.
The impact that the LED steering indicating light detecting device that the utility model provides is not changed by the LED light temperature detects accurately, can make different promptings according to LED lamp damaged condition, for chaufeur provides more selection, has very high practical value.
Description of drawings
Figure l is one of structural representation of the present utility model;
Fig. 2 is two of structural representation of the present utility model.
The specific embodiment
Such as Fig. 1, shown in Figure 2, a kind of LED steering indicating light detecting device, comprise Body control module and the steering indicating light control module that is connected with Body control module, described steering indicating light control module outputs current to the LED lamp, the driving LED lamp is luminous, be provided with memory cell in the described steering indicating light control module, the steering indicating light control module also connects the temperature sensor that is arranged on LED steering indicating light inside, it is characterized in that, described temperature sensor connects the described excess temperature alarm device of an excess temperature alarm device and comprises temperature sensing circuit, comparison control circuit and triggering controllable type warning signal sound alarm circuit.
Described Body control module also connects a turning indicator, and this turning indicator is positioned on the automobile instrument panel.
Each LED steering indicating light inside is provided with a plurality of well-distributed temperature sensors.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification sheets, must determine its technical scope according to the claim scope.
