1、 Appearance inspection 1. Appearance requirements: Approximately 0.5 meters away from the lamp, visually inspect the shell, lampshade, and other parts, and ensure that there is no deformation, scratch, wear, paint peeling, or dirt. The pin has no deformation; Shake the lamp tube without looseness or abnormal noise. 2. Dimensional requirements: The overall dimensions should meet the requirements of the drawings. 3. Material requirements: The materials and structural design of each part of the lamp shall comply with the requirements of the drawings. 4. Assembly requirements: All fastening screws on the surface of the lamp should be tightened without missing installation, the edges should be free of burrs and sharp edges, and all connections should be firm and free from looseness. 2、 Performance requirement 1. LED lighting fixtures need a good heat dissipation system to ensure that the temperature of the aluminum based circuit board does not exceed 65 ℃ when the LED lighting fixtures work in normal environments. 2. LED lamps should have over temperature protection function. 3. LED lighting fixtures have abnormal control circuit protection. LED lighting fixtures must be equipped with 3C or UL or VDE certified fuse devices as overcurrent protection in case of circuit abnormalities. 4. LED lighting fixtures should have the ability to resist LED abnormal operation, that is, in LED lighting fixtures, each LED series group is driven by an independent constant current motor. This constant current circuit should ensure safe operation and stable current in the event of LED breakdown and short circuit abnormalities. 5. LED lighting fixtures should have moisture-proof and moisture removal breathing functions. The internal circuit board of LED lighting fixtures must undergo moisture-proof treatment. The lighting fixtures must have a waterproof and breathable respirator to ensure stable operation in case of moisture, and to eliminate water vapor by relying on the heat generated by their own work. 6. The total downward flux of LED lamps and the energy consumption ratio of the lamps should be ≥ 56LM/W
