Lighting fixtures are subjected to various tests to ensure safe and efficient lighting. These tests are conducted to evaluate the performance, safety, and durability of the fixtures. Below is a detailed explanation of the main tests for lighting fixtures and the devices used in these tests.
1. Photometric Tests
Photometric tests are conducted to determine the light distribution, luminous flux, and color characteristics of fixtures. These tests are critical for assessing the lighting performance and energy efficiency of fixtures.
Devices Used:
- Integrating Sphere: This device measures the total luminous flux and color characteristics of the fixture. The fixture is placed inside the sphere, and the emitted light is evenly distributed across the sphere’s inner surface for measurement.
- Goniophotometer: Used to measure the light distribution of the fixture at different angles. It helps determine the fixture’s luminous intensity distribution and light distribution curves.
2. Electrical Safety Tests
Electrical safety tests assess the electrical safety and compliance of fixtures with relevant standards.
Devices Used:
- High Voltage Test Device (Hipot Tester): Evaluates the insulation resistance and dielectric strength of the fixture. This test determines the fixture’s resistance to high voltages.
- Ground Continuity Test Device: Checks the continuity and reliability of the grounding connections of the fixture.
3. Thermal Tests
Thermal tests are conducted to evaluate the temperature increases and thermal performance of fixtures during operation.
Devices Used:
- Thermal Camera: Visualizes the surface temperatures and temperature distribution of the fixture.
- Temperature and Humidity Chamber: Tests the performance of the fixture under varying temperature and humidity conditions.
4. Mechanical Durability Tests
These tests evaluate the mechanical strength and durability of fixtures.
Devices Used:
- Impact Test Device: Tests the fixture’s resistance to mechanical impacts.
- Vibration Test Device: Evaluates the performance of the fixture in environments with vibrations.
5. IP (Ingress Protection) Tests
IP tests determine the resistance of fixtures to dust and water ingress.
Devices Used:
- Dust Test Chamber: Tests the level of protection the fixture provides against dust ingress.
- Water Test Devices: Conduct various water spray and immersion tests to determine the fixture’s water resistance.
6. EMC (Electromagnetic Compatibility) Tests
EMC tests evaluate the electromagnetic emissions and interactions of fixtures with other devices.
Devices Used:
- EMC Test Chamber (Anechoic Chamber): Measures and analyzes the electromagnetic emissions of the fixture.
- EMI Test Devices: Determines the levels of electromagnetic interference generated by the fixture.
