Lamp reliability testing

LCS Testing specializes in global certification and testing of lighting fixtures. We have established a 5000 large lighting testing laboratory base in Gongming, Shenzhen, equipped with industry standard lighting product safety certification experimental equipment, as well as LED lighting light distribution, color rendering, spectral efficiency, energy source star and other optical testing equipment. This includes a lighting safety laboratory, an electromagnetic compatibility (EMC) laboratory, a lighting energy efficiency laboratory, a light performance and distribution laboratory, and a chemistry laboratory. We can provide global certification and testing services for safety regulations, energy efficiency, electromagnetic compatibility, physical and chemical properties for a wide range of lighting manufacturers.
 
Reliability testing items for lighting fixtures:
 
Salt spray test, high temperature storage, high temperature and high humidity, high and low temperature cycling, service life evaluation, temperature rise test, switch electrical test, vibration test, luminescence maintenance and aging test, lamp function inspection, etc.

🔬  Detailed explanation of reliability testing projects for lighting fixtures

test projectMain purpose and introductionCore standard reference
salt spray testAssess the corrosion resistance of the metal casing, screws, and internal metal components of the lighting fixtures, and simulate harsh coastal or saline atmospheric environments.GB/T 10125 (ISO 9227)
IEC 60068-2-52
ASTM B117
High temperature storageVerify the impact of prolonged exposure to high temperatures in non working conditions on materials (such as plastics and electronic materials) and component performance of lighting fixtures.GB/T 2423.2
IEC 60068-2-2
high temperature and high humidityEvaluate the heat and humidity resistance of lighting fixtures in a constant high temperature and high humidity environment, inspect insulation performance, metal oxidation, material deformation or foaming, etc.GB/T 2423.3
IEC 60068-2-78 (steady-state heat and humidity)
High and low temperature cycleAssess the tolerance of lighting fixtures to drastic temperature changes, verify the physical structural stability, solder joints, and electrical connection reliability caused by material thermal expansion and contraction.GB/T 2423.22
IEC 60068-2-14
Service life assessmentPredicting or verifying the overall lifespan of lighting fixtures is usually based on calculating the time to maintain the luminous flux L70/L50 using light decay data, or evaluating it through accelerated stress testing.IES LM-90 (Lighting fixtures/engines)
IES TM-28 (calculation method)
GB/T 24824
temperature rise testMandatory core project for electrical safety. Measure the temperature of key components (driver, LED beads, housing) of the lighting fixture from normal operation to thermal stability, in order to prevent overheating from causing fires or performance degradation.IEC/EN/GB 7000.1 (safety requirements)
Switching electrical testSimulate frequent switching to assess the resistance of the driving power supply, circuit, and light source to current surges, as well as the durability of mechanical switches.IEC/EN 61347-1 (control device)
Frequently combined with IEC 61058 (switches)
vibration testSimulate the vibration and impact during transportation or use (such as street lamps being exposed to wind or vehicle environments), and verify the structural firmness, screw fastening, and welding reliability.GB/T 2423.10
IEC 60068-2-6
Luminescence Maintenance and Aging TestLuminescence maintenance "refers to the luminous flux maintenance rate, which is obtained through LM-84 (lamp) or LM-80 (LED light source) testing.
Aging test "is a short-term (such as 1000 hours) electrical aging used to stabilize performance and screen for early failures.
IES LM-84, LM-80 (light maintenance)
IEC/PAS 62717 or factory regulations (aging)
