LED's new concept of solid-state light source, with its unparalleled technical advantages of energy saving, environmental protection, long life and high controllability, has become one of the most promising high-tech in the world in recent years, officially kicking off the comprehensive replacement of traditional lighting. Semiconductor lighting technology innovation is changing the history of traditional lighting for a hundred years. With the application of LED technology in the field of lighting, LED products have set off a green storm of energy conservation and environmental protection around the world, and have been praised as “green lighting†products by the industry. Today, with increasing energy consumption, some even predicted: "In the next 10 years, LED products will become the only products that replace traditional lighting fixtures such as high-pressure sodium lamps, incandescent lamps, and fluorescent lamps."
1. Place the LED fixture in a -15 ° C environment
Test method: After the lighting test, the light is controlled by the relay to perform the impact test in this environment;
The test settings are: lighting for 20s, turning off the lights for 20s, and cycling for 100 times;
For the object: test requirements for led lamps (finished lamps with leddriver).
2. The test box is kept at high temperature and low temperature for 0.5h, and it is cycled 8 times.
Test requirements: reference standard: industry experience, power on, lighting 24h, and observe whether the lamp is damaged, the material is deformed by heat and other abnormal phenomena;
Target: LED lamps (finished lamps with leddriver),
The temperature range of the test box is set from -10 ° C to 50 ° C, and the temperature shift rate is: greater than 1 ° C / min, but less than 5 ° C / min.
3. Pack the led lamp samples and place them on the vibration test bench.
After the low temperature and low pressure test, the lamp can not be exposed to paint, discoloration, cracking, material deformation and other abnormal phenomena;
Target: LED luminaire (finished lamps with leddriver) led luminaire test method,
High temperature and high pressure and its impact test: Target: LED lamps (finished lamps with leddriver) test requirements: reference standard: industry experience.
