As shown in fig. 4, which is a specific circuit schematic diagram of eye protection control and illumination control, the front dome lamp control switch, the front dome lamp illumination control switch and the front dome lamp eye protection control switch are implemented by using one front dome lamp switch, and the front dome lamp switch is an electric control switch; a front dome lamp lighting control module and a front dome lamp eye protection control module are arranged in the dome lamp MCU, the input end of the dome lamp MCU receives a front dome lamp switching signal, and the output end of the dome lamp MCU drives the LED dome lamp through a dome lamp driving chip; the ceiling lamp MCU controls a voltage signal for driving the LED ceiling lamp according to the front ceiling lamp switch signal, so that the LED ceiling lamp is in an illumination state and an eye protection working state.
The rear dome lamp control switch, the rear dome lamp illumination control switch and the rear dome lamp eye protection control switch are realized by adopting a rear dome lamp switch which is an electric control switch; a rear dome lamp lighting control module and a rear dome lamp eye protection control module are arranged in the dome lamp MCU, the input end of the dome lamp MCU receives a rear dome lamp switching signal, and the output end of the dome lamp MCU drives the LED dome lamp through a dome lamp driving chip; the ceiling lamp MCU controls a voltage signal for driving the LED ceiling lamp according to the rear ceiling lamp switch signal, so that the LED ceiling lamp is in an illumination state and an eye protection working state. Because adopt a preceding dome lamp electric control switch and a back dome lamp electric control switch, control illumination and eyeshield just need redesign like this, in this application, press preceding dome lamp electric control switch, back dome lamp electric control switch after, corresponding signal can be sent for dome lamp MCU, thereby dome lamp MCU makes LED voltage difference give different light according to the drive of signal drive IC. Taking the control logic of the front dome lamp as an example: the front dome lamp switch button is 1 time, and the dome lamp MCU drives the front dome lamp lighting mode, and the front dome lamp switch button is 2 times, and the dome lamp MCU drives the front dome lamp eye-protecting mode. The switch key of the front dome lamp is pressed for 3 times, and the dome lamp MCU controls the front dome lamp to be turned off. The control logic of the rear ceiling lamp switch is the same as that of the front ceiling lamp switch. The lamp tube can be adjusted according to a cycle sequence, when lighting is pressed for the first time, the MCU is pressed down to control the IC drive to realize an eye protection mode, the lamp tube is pressed down for the third time, and at the moment, lighting is started again when one cycle is finished; certainly, the control logic can also be set to be that the switch is pressed down for times within a certain time, when the switch is pressed down for one time, the ceiling lamp MCU starts illumination, and when the switch is continuously pressed down for two times within a certain time, the MCU starts an eye protection mode; when three times are continued, the dome lamp is turned off.
The difference between the illumination mode and the eye protection mode is realized by controlling the voltage of the LED by the driving IC. The front dome lamp illumination control module, the front dome lamp eye-protecting control module, the rear dome lamp illumination control module and the rear dome lamp eye-protecting control module are integrated together and are realized through a dome lamp MCU. After the lighting signal of the current ceiling lamp is input into the ceiling lamp MCU, the voltage is adjusted by judging through the ceiling lamp MCU (single chip microcomputer), and the lighting mode of the front ceiling Lamp (LED) is driven, and the light is white. After the eye protection signal of the current dome lamp is input into the dome lamp MCU, the judgment is carried out through the dome lamp MCU (single chip microcomputer), the voltage regulation is carried out, the eye protection mode of the front dome Lamp (LED) is driven, and the light is warm. The front dome lamp switch button is 1 time, and the dome lamp MCU drives the front dome lamp lighting mode, and the front dome lamp switch button is 2 times, and the dome lamp MCU drives the front dome lamp eye-protecting mode. The switch key of the front dome lamp is pressed for 3 times, and the dome lamp MCU controls the front dome lamp to be turned off. The control logic of the rear dome lamp switch is the same as that of the front dome lamp switch, and the input signal mode of the rear dome lamp is the same as that of the front dome lamp.
It is clear that the specific implementation of the invention is not restricted to the above-described embodiments, but that various insubstantial modifications of the inventive process concept and technical solutions are within the scope of protection of the invention.
