Scopes & Testing
LED Luminaries General Requirements
Here are some key tests conducted on LED Luminaries:
1) Electrical Safety Tests:
- • Insulation resistance test: Measures the insulation resistance between electrical components.
- • Dielectric withstand test: Checks the ability of the luminaire to withstand high voltage without breakdown.
2) Photometric Tests:
- • Luminous flux measurement: Quantifies the total light output of the luminaire.
- • Luminous intensity distribution measurement: Determines the light distribution pattern and intensity in different directions.
- • Color temperature and color rendering index (CRI) measurement: Evaluates the color quality of the light emitted.
- • Chromaticity coordinates measurement: Specifies the color properties of the light in terms of its position on the CIE chromaticity diagram.
3) Electrical Performance Tests:
- • Power consumption measurement: Determines the electrical power consumed by the luminaire.
- • Power factor and total harmonic distortion (THD) measurement: Assesses the efficiency of power utilization and harmonic distortion of the electrical signal.
4) Thermal Tests:
- • Temperature rise test: Measures the temperature increase of critical components during operation.
- • Thermal imaging: Uses infrared cameras to visualize thermal patterns and identify hotspots.
5) Mechanical Tests:
- • Impact test: Evaluates the luminaire's ability to withstand mechanical shocks and impacts.
- • Vibration test: Assesses the luminaire's resistance to vibration and mechanical stress.
- • IP rating test: Determines the luminaire's level of protection against dust and water intrusion.
6) Durability and Reliability Tests:
- • Endurance testing: Operates the luminaire continuously to assess its long-term performance and reliability.
- • Environmental testing: Exposes the luminaire to extreme temperatures, humidity, and other environmental conditions to evaluate its durability.
7) Flicker and Stroboscopic Effects Tests:
- • Flicker measurement: Analyzes the presence and intensity of flicker in the light output.
- • Stroboscopic effect measurement: Assesses the potential impact of rapid light fluctuations on human vision.
8) Dimming Performance Tests:
- • Dimming range test: Measures the lowest and highest achievable light output levels.
- • Dimming compatibility test: Determines how well the luminaire functions with various dimming systems.
9) Emergency Lighting Tests:
- • Battery discharge test: Evaluates the performance of the luminaire's backup battery during power outages.
- • Duration test: Measures how long the luminaire provides emergency lighting.
10) Electromagnetic Compatibility (EMC) Tests:
- • EMI measurement: Evaluates the luminaire's electromagnetic interference with other electronic devices.
- • Immunity test: Assesses the luminaire's resistance to electromagnetic interference from external sources.
11) Light Distribution and Glare Tests:
- • UGR (Unified Glare Rating) measurement: Quantifies the discomfort caused by glare in indoor lighting.
12) Light Distribution Tests:
- • Goniophotometric measurement: Captures the light distribution pattern in different planes, helping in luminairies placement and design.
13) Labeling and Marking Verification:
- • Verify that the luminaire's labeling, markings, and safety information comply with relevant regulations.
Each test performed at House of Testing contributes to a thorough understanding of the luminaire's performance, safety, and suitability for its intended application. Manufacturers, regulators, and consumers rely on these tests to ensure high-quality, reliable, and safe LED luminaires.
