The present invention is illustrated by taking the application in a vehicle as an example. Please refer to FIG. 1. The embodiment of the warning light control system of the present invention includes a remote control 10 and a plurality of wireless control devices 20 for warning lights.

The remote controller 10 can be operated by personnel. For example, the remote controller 10 can be placed in the driver's seat for personnel to take. It can be seen from FIG. 1 that the remote controller 10 can remotely control at least one warning light wireless control device 20, and different warning lights The wireless control devices 20 can also remotely control each other. Please refer to FIG. 2, each of the warning light wireless control devices 20 is connected to a plurality of light modules 21 for power supply. Each of the light modules 21 may be a light emitting diode (LED) module. The arrangement structure of the plurality of light modules 21 is not limited to The linear arrangement and matrix arrangement can also be irregular or other arrangements. Therefore, the warning light wireless control device 20 and the plurality of lamp modules 21 electrically connected to it form a warning lamp, and the plurality of warning lamps can be installed in the car or Outside the car, for example, it can be installed on the driver's seat, front, body, or rear of the car as required.

Please refer to FIG. 2, each of the warning light wireless control devices 20 includes a wireless transceiver 22 and a microcontroller (MCU) 23. The microcontroller 23 is electrically connected to the plurality of lamp modules 21 and the wireless transceiver 22. The microcontroller 23 includes two power contacts to receive a DC working power supply VDC. For example, the power contacts of the microcontroller 23 can be used for power supply. Connect the battery or on-vehicle power supply line or equipment to receive the DC working power VDC. The microcontroller 23 drives the plurality of lamp modules 21 according to one of the plurality of lighting modes. The program instructions of the plurality of lighting modes can be stored in a memory for the microcontroller 23 to read. The number, combination, and/or flashing frequency of the plurality of lamp modules 21 driven to be lit by different lighting modes can be different from each other. When the microcontroller 23 receives a mode switching command SW through the wireless transceiver 22, it switches from the lighting mode in the plurality of lighting modes to another lighting mode to drive the plurality of lamp modules 21, and its mode The switching method may be, for example, sequential and cyclic switching.

On the other hand, when the microcontroller 23 of each of the warning light wireless control devices 20 determines that multiple mode switching commands SW have been received within a threshold time, the microcontroller 23 only receives it at the earliest within the threshold time. The received mode switching command SW implements a switching of the lighting mode, wherein the receiving time point of the mode switching command SW received earliest is the starting time point of the threshold time, and the threshold time is the micro A preset value of the controller 23.

The microcontroller 23 includes a setting pin S. In addition to driving the plurality of lamp modules 21 according to the lighting mode, the microcontroller 23 also judges whether to drive in reverse according to the level of the setting pin S. The plural lamp modules 21. For example, when the setting pin S is at a high level, that is, the setting pin S is electrically connected to the positive pole (+) of the DC working power supply VDC, the microcontroller 23 can use a non-inverting manner according to the lighting mode Drive the plurality of lamp modules 21; relatively, please refer to Figure 3, when the setting pin S is low, that is, the setting pin S is electrically connected to the negative (-) of the DC working power supply VDC, and the microcontroller 23 can drive the plurality of lamp modules 21 in an inverted manner according to the lighting pattern.

4, for example, the left tail door 31 and the right tail door 32 of the truck 30 are respectively equipped with a warning light wireless control device 20, and each warning light wireless control device 20 is electrically connected to four light modules 21 arranged in a straight line. When the warning light wireless control device 20 of the left tailgate 31 and the warning light wireless control device 20 of the right tailgate 32 both implement non-inverting driving, as shown in FIG. 4, in a lighting mode, the two left light modules are driven 21 flashes, and the other two light modules 21 on the right side are off. It can be seen that the lighting states of the left tail door 31 and the right tail door 32 are synchronized. On the other hand, suppose that the wireless warning light control device 20 of the left tailgate 31 implements non-inverting drive, and the wireless warning light control device 20 of the right tailgate 32 implements reverse drive, it is still in the lighting mode, please Referring to FIG. 5, it can be seen that the left tail door 31 and the right tail door 32 have opposite lighting states. The warning light wireless control device 20 of the right tail door 32 drives the two right light modules 21 to flash, while the other two lights on the left side Module 21 is off. It can be seen from the above examples that the user can decide whether to implement inverting driving according to requirements.

Therefore, when the present invention is applied to a vehicle, the user can connect one of the warning light wireless control devices 20 to the light module 21 and put it in the driver's seat, and the other warning light wireless control devices 20 can be connected to the light module 21. Installed outside the car, although the user cannot see the lighting status outside the car in the driver's seat, the lighting mode implemented by the driver's seat and the warning light wireless control device 20 outside the car is the same, only non-inverted drive and inverted The driving difference, so the user can directly infer the lighting state outside the car by observing the lighting state of the driver's seat.
