First, high temperature and high pressure and its impact test: Target: LED lamps (finished lamps with LEDDriver) Reference standard: industry experience Test Methods: 1. Place 5 LED lamps in a room with a room temperature of 60 °C; 2. Adjust the input voltage of the LED lamp to 1.1 times the maximum rated input voltage through a voltage regulator; 3. Turn on the power, turn on the light 24H, and observe whether the lamp is damaged or the material is deformed by heat; 4. After the lighting test, the impact test is carried out in this environment through the relay control lamp. The test setting is: lighting for 20s, extinguishing for 20s, and cycling for 100 times. Testing requirements: A. After the high temperature and high pressure test, the lamp can not be exposed to paint, discoloration, cracking, material deformation and other abnormal phenomena; B. After the impact test, the lamp can not be electrically anomalous such as leakage or lighting. Second, low temperature and low pressure and its impact test: Target: LED lamps (finished lamps with LEDDriver) Reference standard: industry experience Test Methods: 1. Place 5 LED lamps in a -15 °C environment; 2. Adjust the input voltage of the LED lamp to 0.9 times the minimum rated input voltage through a voltage regulator; 3. Turn on the power, turn on the light 24H, and observe whether the lamp is damaged or the material is deformed by heat; 4. After the lighting test, the impact test is carried out in this environment through the relay control lamp. The test setting is: lighting for 20s, extinguishing for 20s, and cycling for 100 times. Testing requirements: A. After the low temperature and low pressure test, the lamp can not have abnormal phenomena such as surface paint stripping, discoloration, cracking and material deformation; B. After the impact test, the lamp can not be electrically anomalous such as leakage or lighting. 5V 3A Usb Charger,5V3A Wall Charger,5V3A Usb Wall Charger,5V 3A Usb Output Charger Guangdong Mingxin Power Technologies Co.,Ltd. , https://www.mxpowersupply.com
