[0002] An integrating sphere is a device used for optical measurement, commonly used to measure parameters such as luminous flux, color temperature, and spectral power distribution of a light source. RGB ambient lighting is increasingly used in automobiles. However, due to factors such as LED production processes, the color and brightness of RGB ambient lights vary from batch to batch. This results in inconsistent color and brightness after mixing, severely impacting the customer experience. Therefore, color and brightness calibration is required for each RGB ambient light node before it leaves the production line.

The industrial computer adjusts the duty cycle of the red, green, and blue chip currents according to the ratio of the duty cycles of the red, green, and blue chip currents so that the RGB ambient light meets the required brightness. The industrial computer writes the adjusted duty cycle data of the red, green, and blue chip currents into the memory inside the RGB ambient light. This utility model can configure different batches of RGB ambient lights to the target color and brightness.
