The invention discloses a welcome lamp circuit, a welcome lamp device, a welcome lamp and an automobile provided with the welcome lamp. A CAN signal processing chip of the welcome lamp circuit is used for reading and decoding a welcome lamp starting signal sent to the welcome lamp circuit; the MCU power conversion circuit is used for supplying power to the CAN signal processing chip and the central processing unit; the lamplight controller receives a welcome starting signal sent by the vehicle body bus CAN, and switches different LED light sources according to an illuminance signal provided by the sunlight and rainfall sensor or a reversing signal provided by the vehicle body bus CAN; the LED light source of the welcome lamp circuit is matched with the film of the welcome lamp under the action of the LED voltage-stabilizing driving circuit, so that the diversity of welcome patterns is realized, a welcome scheme can be started when a vehicle is turned on, an illumination signal of the surrounding environment of the vehicle can be judged by combining a sunlight and rainfall sensor, and the illumination signal can be judged according to different geographic positions and time. And starting different welcome schemes.
本发明公开了一种迎宾灯电路、装置、迎宾灯和安装有该迎宾灯的汽车,迎宾灯电路的CAN信号处理芯片用于读取向迎宾灯电路发送的启动迎宾灯的信号并进行解码;MCU电源转换电路用于向CAN信号处理芯片和中央处理器提供电源;灯光控制器接收从车身总线CAN发来的迎宾启动信号,根据阳光雨量传感器提供的照明度信号或车身总线CAN提供的倒车信号切换不同的LED光源;迎宾灯电路的LED光源在LED稳压驱动电路的作用下与迎宾灯的菲林片相互配合,实现迎宾图案的多样化,不仅能够做到车辆打开时启动迎宾方案,还能够结合阳光雨量传感器判断车辆周边环境的照度信号,根据所处的地理位置和时间的不同,启动不同的迎宾方案。
