Flicker Test: Comprehensive Analysis Using LISUN LSRF-3 Lamp Start, Run-Up Time, and Flicker Test System

Abstract
Flicker testing has become an essential process in assessing the performance of modern lighting systems. With increasing adoption of LED lighting, understanding and evaluating flicker parameters is crucial for ensuring quality and compliance with international standards. This paper delves into the technical aspects of flicker testing, focusing on the LISUN LSRF-3 Lamp Start, Run-Up Time, and Flicker Test System. The article explores its operational principles, key features, applications, and provides a comprehensive data analysis to highlight its effectiveness in performing flicker tests.

Introduction
Flicker, the rapid variation in light intensity perceived by the human eye, is a critical parameter affecting lighting quality. It can cause discomfort, health issues, and operational inefficiencies. Hence, flicker tests are fundamental in ensuring that lighting products meet stringent regulatory and user expectations. The LISUN LSRF-3 system is a specialized tool for flicker testing, designed to measure parameters like lamp start time, run-up time, and flicker.

Importance of Flicker Test

Definition and Impact

Flicker is defined by variations in luminous flux over time. It can arise due to power supply fluctuations, driver instability, or design inefficiencies in lighting systems. High flicker levels can lead to:

• Visual Discomfort: Sensitivity to light fluctuations.
• Health Concerns: Headaches, eye strain, and even neurological effects.
• Performance Issues: Reduced concentration and productivity.

Regulatory Standards

Several standards govern flicker testing, including:

• IEEE 1789-2015: Guidelines on acceptable flicker levels.
• IEC TR 61547-1: Defines test methods for lighting immunity.
• California Title 24: Energy and flicker compliance for lighting systems.

Methodology of Flicker Test Using LSRF-3
Test Setup
• Equipment Placement: Position the lamp under test (LUT) on the test bench.
• System Calibration: Ensure the LSRF-3 is calibrated for accurate measurements.
• Parameter Selection: Choose flicker metrics such as Pst (short-term flicker), SVM (Stroboscopic Visibility Measure), and percent flicker.
• Data Acquisition: Record and analyze luminous intensity variations over time.

Measured Parameters：

Parameter	Description
Percent Flicker	Amplitude of variation in light output.
Flicker Index	Ratio of areas above and below average light output.
SVM	Stroboscopic effect visibility measure.
Pst	Perceptibility of short-term flicker variations.

Data Analysis and Results
Experimental Setup
• Test Lamp: LED bulb, 10W, 4000K.
