The invention relates to the technical field of automobile backlight illumination and control, and provides an automobile B-pillar backlight and a control method thereof. The automobile B-pillar backlight comprises a backlight source and a B-pillar cover plate; detecting the environment illumination intensity in the automobile in real time; the environment illumination intensity is compared with a set light intensity threshold value, and when the environment illumination intensity is lower than the set light intensity threshold value, a backlight source starting signal is sent out; after a backlight starting signal is received, the difference value between the light intensity threshold value and the environment illumination intensity is calculated, and the conversion efficiency of the backlight and the power supply voltage are combined to calculate the required current of the backlight; acquiring a control strategy according to the required current of the backlight source, and correspondingly controlling the current of the backlight source according to the control strategy; if the B-pillar cover plate adopts a liquid crystal display panel, the B-pillar cover plate also controls transmission and provides patterns and/or characters for display. Lamplight decoration can be formed on the automobile B column, and on one hand, the illumination effect in an automobile is improved; and on the other hand, the integrality of the interior lighting is enhanced.
本发明涉及汽车背光灯照明与控制技术领域,提供了一种汽车B柱背光灯及其控制方法,汽车B柱背光灯包括背光源与B柱盖板;实时检测汽车内部的环境光照强度;将环境光照强度与设定的光强阈值进行对比,当环境光照强度低于设定的光强阈值时,发出启动背光源信号;在接收到启动背光源信号后,计算光强阈值与环境光照强度的差值,结合背光源的转换效率和电源电压,计算得到背光源的需求电流;根据背光源的需求电流,获取控制策略,根据控制策略对背光源的电流进行相应控制;若B柱盖板采用液晶显示板还控制传输提供图形和/或文字用于显示。本发明可以在汽车B柱形成灯光装饰,一方面提高车内照明效果;另一方面增强车内灯饰的整体性。
