Two national standards in the lighting field approved for publication

This document applies to light sources, control gear and [[7. 灯具与光学配光|Luminaire]]s equipped with integrated control devices. It specifies the method for determining the inrush current of lighting products, aiming to determine the peak inrush current and inrush current pulse duration of one or more similar lighting products. This provides critical parameter information for electrical designers, [[9. 照明方式与应用|Lighting design]] professionals and installers to correctly select components such as switching equipment and overcurrent protection devices, ensuring compatibility between the lighting system and other installed components. This ensures that overcurrent protection responds quickly to overloads or short circuits, preventing circuit interruption (i.e., nuisance tripping) caused by inrush currents, whose maximum peak current is typically far higher than the steady-state current during normal operation. Accurate determination of the inrush current characteristics of lighting products is necessary to effectively guide the R&D manufacturing of lighting products and the design, installation, inspection and acceptance of lighting engineering projects, thereby safeguarding the safety of lighting products, their power grid and on-grid equipment.

The purpose of this document is to provide background information and detailed explanations on electrical safety technical topics such as mathematical addition of working voltage, insulation between circuits, use of PELV, and insulation between LV power and control line conductors. This not only aids in the understanding and implementation of mandatory National standards (mandatory / recommended) related to lighting electrical safety but also provides guidance for product design development and compliance design for insulation requirements during various product interactions in application processes.
