Problems solved by technology

[0002] At present, RGB ambient lights are more and more widely used in automobiles, but due to LED production process and other reasons, the color and brightness of different batches of RGB ambient lights have certain differences, resulting in inconsistent colors and brightness after mixed light, which seriously affects customer experience. Therefore, when each RGB ambient light node goes offline, it needs to calibrate the color and brightness

Abstract

The invention belongs to the technical field of intelligent calibration and relates to in-vehicle RGB atmosphere lamp color and luminance calibration equipment. The in-vehicle RGB atmosphere lamp color and luminance calibration equipment comprises an integrating sphere, a spectrograph and an industrial personal computer. The industrial personal computer calculates the duty ratios of currents passing through red chips, green chips and blue chips when required colors are met, the industrial personal computer adjusts the duty ratios of the currents of the red chips, the green chips and the blue chips according to the proportion of the dust ratios of the currents of the red chips, the green chips and the blue chips so that an RGB atmosphere lamp can meet required luminance, and the industrialpersonal computer writes the adjusted duty ratio data of the currents of the red chips, the green chips and the blue chips into a memorizer in the RGB atmosphere lamp. By means of the in-vehicle RGB atmosphere lamp color and luminance calibration equipment, different batches of RGB atmosphere lamps can be configured to target colors and luminances.

Description

technical field [0001] The invention belongs to the technical field of intelligent calibration, and relates to an equipment and method for calibrating the color and brightness of an RGB ambient light in a car. Background technique [0002] At present, RGB ambient lights are more and more widely used in automobiles, but due to LED production process and other reasons, the color and brightness of different batches of RGB ambient lights have certain differences, resulting in inconsistent colors and brightness after mixed light, which seriously affects customer experience. Therefore, when each RGB ambient light node goes offline, it needs to calibrate the color and brightness. [0003] The RGB ambient light contains 3 chips, which are red, green, and blue chips. The color and brightness of the RGB ambient light can be adjusted through the duty cycle of the current flowing through the red, green, and blue chips. In addition, the RGB ambient light also includes a memory in the RG...
