LED Luminaries Performance
Testing the performance of LED luminaires is crucial to ensure they meet quality, safety, and efficiency standards.
Scopes & Testing
LED Luminaries Performance
Here are some key performance tests you should consider when evaluating LED luminaires:
1) Luminous Flux and Efficacy Testing:
- • Measure the luminous flux (total light output) of the luminaire in lumens (lm).
- • Calculate luminous efficacy by dividing luminous flux by input power in watts (lm/W). This indicates the efficiency of converting electrical power into visible light.
2) Color Characteristics Testing:
- • Measure color temperature in Kelvin (K) to determine the perceived color of the light.
- • Calculate the color rendering index (CRI) to assess how accurately the light source renders colors compared to a reference source.
3) Light Distribution and Uniformity Testing:
- • Use a goniophotometer to analyze the light distribution pattern and intensity in different directions.
- • Evaluate illuminance levels across the illuminated area to ensure uniform lighting.
4) Flicker and Stroboscopic Effects Testing:
- • Measure flicker percentage, flicker index, and modulation depth to assess potential flicker issues that could cause discomfort or health concerns.
5) Dimming Performance Testing:
- • Test the luminaire's performance with different dimming systems to ensure smooth and consistent dimming without flicker or color shifts.
6) Electrical Performance Testing:
- • Measure input power to determine energy consumption.
- • Assess power factor and total harmonic distortion (THD) to evaluate electrical efficiency and harmonic content.
7) Temperature Testing:
- • Monitor the operating temperature of critical components to ensure they stay within safe limits.
- • Use thermal imaging to identify areas of excessive heat.
8) Lifetime and Lumen Maintenance Testing:
- • Conduct accelerated life testing or use LM-80 data to estimate the expected lifetime of the luminaire.
- • Measure lumen maintenance over time to predict how the light output will degrade.
9) Ingress Protection (IP) Testing:
- • Verify the luminaire's level of protection against dust and water using IP rating tests.
10) Mechanical Durability Testing:
- • Perform impact and vibration tests to assess the luminaire's resilience to mechanical stress and shocks.
11) Emergency Lighting Testing:
- • Evaluate the performance of backup batteries during power outages to ensure proper emergency lighting.
12) Electromagnetic Compatibility (EMC) Testing:
- • Assess electromagnetic interference (EMI) to ensure the luminaire doesn't interfere with other electronic devices.
- • Test immunity to external electromagnetic interference.
13) Glare Testing:
- • Use the Unified Glare Rating (UGR) to evaluate glare discomfort in indoor lighting settings.
14) Labeling and Marking Verification:
- • Ensure that the luminaire's labeling, markings, and safety information comply with relevant regulations.
15) Performance Reporting:
- • Document all test results, methods, and conditions in a comprehensive test report.
- • Compare the results with industry standards and specifications to determine compliance.
House of Testing Lab conducts these performance tests to ensure that LED luminaires meet quality and safety standards, provide reliable illumination, and fulfill their intended purpose effectively.
