According to the requirements of IEC60598 and GB7000 standards, the lamps may encounter rough handling or operation during normal installation, use and maintenance. The lamps should have sufficient mechanical strength to ensure that they are still safe. This requirement is suitable for luminaires used in general places. From the perspective of impact energy, the mechanical strength requirement is low, and only the luminaire is required to be subjected to a slight bump without causing damage to safety. The test object is to provide protection against electric shock and ultraviolet protection, tungsten halogen lamp cover, dustproof, solid foreign matter, waterproof protection lampshade, outer casing and electrical components, and ceramics and small parts within 26mm of the outer casing or surface area not exceeding 4cm2. . The specimens are mounted or supported on a piece of hardwood board for normal use and are impacted three times with the spring impact hammer at the weakest possible point, paying particular attention to the insulating material surrounding the live parts and the insulating bushing. A sample may have multiple weak points, and the sample may be attached to find the weakest part. If the test result is in doubt, the new sample is retested, and only the weakest part of the new sample is impacted three times. Lampholders and other components shall comply with the mechanical strength requirements specified in the respective component standards, and shall only be repeated as required by this section if they exceed the projection of the shape of the luminaire. The impact energy of the sample is divided according to the object to be washed. The fragile parts are provided with dustproof and anti-solid foreign matter and waterproof glass and translucent cover, UV protection and tungsten halogen lamp cover and ceramic and within 26mm beyond the outer casing or Small parts with a surface area not exceeding 4 cm2. The spring impact test is qualified for damage to the test sample that does not pose a safety hazard. The spring impactor produced by Zhitongtong is easy and reliable to operate and durable when applied to the mechanical strength test of the luminaire.
