The invention relates to the technical field of electronics, in particular to an automobile atmosphere lamp temperature compensation control method, which comprises the following steps: acquiring a temperature change curve of an automobile atmosphere lamp module, and putting the temperature change curve into software engineering; the software engineering puts the automobile atmosphere lamp module into the calibration tool and sends room temperature data to the automobile atmosphere lamp module for testing to obtain an initial room temperature reference value; the calibration tool measures the three-color coordinates and the brightness value of the automobile atmosphere lamp module respectively, and inputs the three-color coordinates and the brightness value into the automobile atmosphere lamp module for storage; according to the method, the PN junction voltage change curve of the automobile atmosphere lamp module is measured in real time through software engineering, the PN junction voltage change curve and the temperature change curve are substituted into a software light mixing library for operation and output compensation, the PN junction voltage of the RGB-LED is measured and then converted into the RGB-LED temperature, the RGB-LED temperature change curve is combined, and parameter values corresponding to the curve are substituted into the light mixing library for operation and output compensation. And the problem of chromaticity coordinate change caused by manufacturing process difference and junction temperature change is effectively reduced.
