Description

Technical Field

[0001] This invention relates to automotive electronic components, specifically an LED auxiliary lighting device. Background Technology

[0002] This invention is an alternative to the "car turning headlights follow" function. For cars that are not equipped with this function, the current solution on the market is to modify the original headlights. The modification solution has high technical requirements and has the disadvantages of disassembling, flashing and cutting wires, which pose certain safety hazards. This invention is an aftermarket solution that does not require modification of the original vehicle wiring harness and can effectively avoid the above disadvantages. Summary of the Invention

[0003] This invention is composed of multiple microcontroller modules, mainly including a light sensor switch module, a mercury switch-controlled RF transmitter module, an RF receiver module, a miniature time-delay relay module, an FFC flexible cable, a 12V battery, and an LED lamp body.

[0004] This invention consists of two parts: a control part consisting of a miniature 12V battery, a light-sensing switch module, and an RF transmitting module controlled by a mercury switch (one RF transmitting module can be equipped with multiple RF receiving modules); and a controlled part consisting of an RF receiving module, a miniature time-delay relay, an FFC flexible flat cable, and an LED lamp body (the wiring principle of the two controlled parts is exactly the same, and both are directly powered by the car battery).

[0005] The installation method of this invention involves installing the control unit on the back of the car steering wheel, installing two sets of controlled units on both sides of the car engine compartment, and installing the LED lamp body separately on the headlight cover or on the fender next to the cover. The connection between the LED and the relay is completed by an FFC flexible flat cable (the FFC cable can effectively pass through the gap between the headlight body and the fender).

[0006] [The working principle of this invention is as follows: A 12V battery-powered light sensor switch module is used. The normally open output of the light sensor switch module is connected to an RF transmitter module controlled by a mercury switch. When there is insufficient light, the sensor switch is automatically turned on (the light sensor sensitivity is adjustable). At this time, when the steering wheel is turned to one side to a certain angle, the mercury switch on that side is turned on to complete the RF transmitter module to complete the signal transmission (when the steering wheel is turned almost a full circle, both mercury switches can complete one turn). The signal output terminal of the RF receiver module is connected to the coil terminal of a miniature time-delay relay. The normally open output terminal of the relay is connected to an LED light. When the RF receiver module receives a signal, the relay coil is energized and the normally open terminal is turned on, and the LED is powered on to achieve illumination (the illumination time of a single signal can be set through the time-delay relay).] Attached Figure Description
