The invention discloses an interactive display lamp chromatic aberration compensation method, an interactive display lamp and an automobile. The chromatic aberration compensation method comprises the steps that the expected color type of an RGB Mini LED light source is determined; power is supplied to a red light LED, a green light LED and a blue light LED of the RGB Mini LED light source according to the expected color type of the RGB Mini LED light source, and the red light, the green light and the blue light form colored light after being superposed and mixed; according to the real-time temperature of the working environment of the RGB Mini LED light source, the power supply current of the RGB Mini LED light source is adjusted, the brightness of the green light LED and the brightness of the blue light LED are changed, and the red light, the changed green light and the changed blue light are overlapped and mixed to form compensated colored light, so that the color difference caused by temperature change is reduced; the interactive display lamp comprises a lampshade, a lamp shell, a lamp source and a display lamp driving assembly. According to the invention, a to-be-displayed graph containing multiple colors can be formed, contents such as characters, patterns or animation frames capable of interacting with pedestrians can be formed, and the color difference of the RGB Mini LED light source due to temperature rise can be reduced.
本发明公开了一种交互显示灯色差补偿方法、交互显示灯以及汽车,所述色差补偿方法包括:确定RGB Mini LED光源的预期颜色类型;根据RGB Mini LED光源的预期颜色类型,向RGB Mini LED光源的红光LED、绿光LED以及蓝光LED供电,红光、绿光和蓝光叠加混合后形成彩色光;根据RGB Mini LED光源的工作环境实时温度,调节RGB Mini LED光源的供电电流大小,改变绿光LED和蓝光LED的亮度,红光、改变后绿光和改变后蓝光叠加混合后形成补偿后彩色光,以降低因温度变化而出现的色差;所述交互显示灯包括灯罩、灯壳、灯源以及显示灯驱动总成。本发明能够组成包含多种颜色的待显示图形,形成能够与行人进行交互的文字、图案或动画帧等内容,并且能够降低RGB Mini LED光源因温度上升而出现的色差。
