The invention discloses a light-emitting license plate and a motor vehicle. A light-emitting license plate includes a substrate, a plurality of LED light-emitting chips, a photosensitive sensor and aprocessor. The plurality of LED light-emitting chips are arranged on a first surface of the substrate to form an LED display device, and the LED light-emitting chips comprise red light LED chips, green light LED chips and blue light LED chips. The LED display device is used for displaying license plate characters. The photosensitive sensor is adjacent to the LED display device, is arranged on thefirst surface and is used for sensing ambient light brightness. The processor is arranged on the first surface of the substrate or a second surface of the substrate, is connected with the photosensitive sensor and the LED display device, and is used for adjusting the light-emitting brightness and/or the light-emitting color of the LED display device according to the ambient light brightness sensedby the photosensitive sensor. The effect that the characters of the license plate are clearer when the ambient light brightness is low or the visibility of the license plate is increased when the ambient visibility is low is achieved.
本发明公开了一种发光车牌及机动车。一种发光车牌,包括:基板;LED发光芯片,多个所述LED发光芯片设置于所述基板的第一面以形成LED显示装置,所述LED发光芯片包括红光LED芯片、绿光LED芯片和蓝光LED芯片;所述LED显示装置用于显示车牌字符;光敏传感器,邻近所述LED显示装置设置在所述第一面,用于感应环境光亮度;处理器,设置在所述基板的所述第一面或所述基板的第二面,与所述光敏传感器和所述LED显示装置连接,用于根据所述光敏传感器感应到的环境光亮度调整所述LED显示装置的发光亮度和/或发光颜色。达到了在环境光亮度较低时使车牌字符更加清晰,或在环境能见度低时增加车牌的可见度的效果。
