Embodiment 1

[0047] In this embodiment, the non-halogen lamp is used as a car light. An anti-backflow circuit for preventing circuit current backflow is provided between the power input and the subsequent electronic circuit, and a controllable resistance load circuit for simulating the halogen lamp is arranged after the anti-backflow circuit. The resistance load circuit is used to act as a halogen lamp load during the detection of the automobile system so that the detection result is in a normal state. At the same time, a filter circuit is set before the power output to prevent the charging current from being too large and play a filtering role. The method of this embodiment solves the problem of misjudgment of the vehicle system when the non-halogen lamp is used as a car light, so that the non-halogen lamp can be used in the field of car lights instead of the halogen lamp.

Embodiment 2

[0049] The decoding circuit of this embodiment is used when non-halogen lamps are used as vehicle lights. The decoding circuit is connected between the power supply and the non-halogen lamp. The structure diagram of the decoding circuit is as follows: Figure 4 As shown, the decoding circuit includes a decoding circuit control system, an anti-backflow prevention module for preventing circuit current backflow, a load simulation module for simulating the resistance load of a halogen lamp, and a filter module for preventing excessive charging current and serving as a filter. The anti-backflow module, the load simulation module and the filter module are electrically connected in sequence; the power input positive terminal and the power input negative terminal are electrically connected to the anti-backflow module, and the filter module is connected to the power output positive terminal and the power output negative terminal; the decoding circuit control system can be controlled by ...

Embodiment 3

[0058] The decoding circuit in this embodiment includes a decoding circuit control system, a backflow prevention module, a load simulation module and a filter module. The anti-backflow module, the load simulation module and the filter module are electrically connected in sequence; the power input positive terminal and the power input negative terminal are electrically connected to the anti-backflow module, and the filter module is connected to the power output positive terminal and the power output negative terminal; the decoding circuit control system can be controlled by a microcomputer system or a control system composed of analog circuits, the output control one of the decoding circuit control system is connected to the load analog module, and the output control two of the decoding circuit control system is connected to the filter module.

[0059] Wherein, the load simulation module and the filter module adopt the structure of the second embodiment. The structure of the an...

Abstract

The method for using a non-halogen lamp as a car lamp and the decoding circuit and its working method of the present invention are applied in the field of automobile lamps. One of the objects of the present invention is to provide a method for using a non-halogen lamp as a car lamp, which solves the problem of non-halogen lamps. The problem of misjudgment in automobile system detection when halogen lamps are used as car lights makes it possible for non-halogen lamps to replace halogen lamps in the field of car lights. The second object of the present invention is to provide a decoding circuit for a non-halogen lamp used as a car lamp, which is connected between the power supply and the non-halogen lamp, so that the non-halogen lamp can be lit normally when used as a car lamp. Another object of the present invention is to provide a working method for a decoding circuit of a non-halogen lamp used as a car lamp, so that the decoding circuit can well simulate the load characteristics of the halogen lamp and prevent excessive charging current, and can be used in different automotive systems. The detection signals of different car models enable the car system to judge it to be in a normal state during detection.

Description

technical field [0001] The invention relates to the technical field of vehicle electronics. Background technique [0002] With the advancement of technology, in addition to halogen lamps, other types of light source lamps can also be applied to automobiles as vehicle lighting, such as xenon lamps, LED lamps, etc. However, many brand models on the market only consider the use of halogen lamps as headlights when designing automotive systems. Non-halogen lamps such as xenon lamps and LED lamps are used in this type of car and cannot be lit normally, and often appear to be unable to light up, work unstable, or even burn out the car circuit. After research, the car lights cannot be turned on normally for the following reasons: [0003] 1. Because the load characteristics of non-halogen lamps are different from those of halogen lamps, it causes misjudgment in the detection of automotive systems [0004] When this type of car turns on the power of the car system, the car system ...
