一种自动检测后牌照灯配光要求的软件

Software for Automatically Detecting the Photometric Distribution of Rear-Registration Plate Lamp

后牌照灯作为一种用于照明后牌照板空间区域的装置,在设计时应满足对应的法规配光要求。在判定配光设计是否满足要求时,工程师一般要手动拾取记录法规点的亮度值,再计算任意两个测量点的亮度梯度。为提高计算效率,规避低级错误,基于VBA开发了一款自动计算法规点亮度值及梯度的软件,用以快速准确检测后牌照灯配光设计是否符合法规要求,从而提高工作效率和质量。

As a illuminating device for lighting up the rear-registration plate, the rear-registration plate lamp is to meet the photometric distribution specified in standard. When determining whether the photometric distribution meets the standard or not, engineers generally need to manually pick up and record the brightness value of the test points, and then calculate the gradient of any two test points. In order to improve the calculation efficiency and avoid low-level errors, one kind of software for automatically calculating the brightness value and gradient of the test points is developed based on VBA, which can be used to quickly and accurately check whether the photometric distribution of the rear-registration plate lamp meets the regulatory requirements or not, thereby improving working efficiency and quality.
