The invention relates to a color matching method of an interior lamp and an interior lamp system. The invention discloses a color matching method for an interior lamp. The method comprises the following steps: S1, reading parameter information of an LED lamp; s2, receiving a target value; s3, color coordinate space transformation: expressing the parameter information of the target color as coordinate transformation information under a CIE1931 color coordinate system; s4, color gamut judgment: judging whether the coordinate conversion information of the target color exceeds a preset color gamut region or not; if the coordinate conversion information of the target color does not exceed the preset color gamut region, performing a step S5; s5, color mixing calibration, wherein the PWM duty ratio needing to be output is obtained according to the coordinate conversion information of the target color and the parameter information of the LED lamp in the step S1; and S6, outputting a control instruction: the lamp controller outputs a light emitting instruction of the LED lamp according to the PWM duty ratio needing to be output. According to the invention, the problems of color difference among a plurality of LEDs and difference between the actual color and the target color are effectively solved.
本发明涉及一种内饰灯的调色方法及内饰灯系统。一种内饰灯的调色方法,包括如下步骤:S1、读取LED灯的参数信息;S2、接收目标值;S3、色坐标空间变换:将目标色的参数信息表达为CIE1931色坐标系下的坐标转换信息;S4、色域判定:判断目标色的坐标转换信息是否超出预设的色域区域;若目标色的坐标转换信息未超出预设的色域区域,则进行步骤S5;S5、混色校准:根据目标色的坐标转换信息以及步骤S1的LED灯的参数信息获得需要输出的PWM占空比;S6、输出控制指令:灯控制器根据需要输出的PWM占空比输出LED灯的发光指令。本发明有效地解决多颗LED间的颜色差异以及实际颜色和目标颜色差异的问题。
