This dataset focuses on analyzing the impact of LED substrate locking torque on the seismic performance of emergency lighting fixtures for sports venues, revealing the quantitative relationship between mechanical fastening parameters and component connection reliability. It provides critical decision-making support for the company (as a manufacturer) and external stakeholders, holding significant application value, which is specifically reflected in the following aspects:
1. Optimizing mechanical fastening processes and assembly quality control: The company can accurately formulate torque control standards for substrate installation and establish scientific assembly process specifications by analyzing the impact of different locking torques on the seismic performance of the fixtures, thereby significantly enhancing the structural connection reliability and long-term stability of emergency lighting systems in sports venues under vibration conditions.
2. Promoting the development of precision assembly technology and intelligent fastening systems: This dataset can offer support for fastener suppliers, assembly process engineers, and sports facility construction parties, assisting them in studying the correlation mechanism between torque parameters and connection performance, developing high-precision torque control systems and intelligent assembly testing equipment, and advancing the R&D and industrial application of professional sports lighting products with excellent seismic durability.

Standard data processing procedures are as follows:
1. Data collection: Real-time recording of seismic performance test data of emergency lighting fixtures for sports venues under different LED substrate locking torques, including fields such as test sample number, test time, LED substrate locking torque/N·m, and seismic performance grade.
2. Data preprocessing: (1) Denoise the collected data to ensure data accuracy. (2) Aggregate the historically collected data (including this batch of test data) to form dataset X, and calculate the average value of the seismic performance grade field in dataset X.
3. Calculating linear regression slope a and intercept b: Based on dataset X (taking LED substrate locking torque as the independent variable and seismic performance grade as the dependent variable), use the SLOPE function to determine the slope a according to the least squares principle, and use the INTERCEPT function to determine the intercept b. The slope a represents the degree of influence of unit change in LED substrate locking torque on the seismic performance grade of emergency lighting fixtures for sports venues, while the intercept b represents the seismic performance grade value of the emergency lighting fixtures for sports venues under the reference LED substrate locking torque.
4. Result application: (1) Calculate the proportional coefficient k: k = |a / average seismic performance grade| × 100%; (2) If k ≥ 10%, it is judged as "high impact"; if 5% ≤ k < 10%, it is judged as "medium impact"; if k < 5%, it is judged as "low impact".
