The waterproof test should be a test item immediately after the aging test. In this way, we can imitate the real environment to test the real IP protection level of LED wall washing lamp. This method is generally called thermal measurement. After the light of the lamp is hot, there will be a phenomenon of thermal expansion and contraction of the lamp. At this time, the test can really test whether the LED wall washing lamp can be used in the outdoor harsh environment, so as to ensure that the water and dust-proof ability of the lamp is no problem under the conditions of wind, rain, sun and so on.
Defect test is a very important test item in product certification test. This test item is to short circuit or open some components on the circuit to simulate the possible faults in the actual use process, and then evaluate the safety of the product under the condition of single fault. In order to meet this safety requirement, the brand of LED line lamp should consider adding appropriate fuse at the input end of the product in the product design, so as to prevent the output short circuit or internal component fault from over-current and then lead to fire hazard.
Temperature rise test
Temperature rise test is a necessary item of product safety test, which has certain temperature rise constraints on different components. In the product design stage, the manufacturer should pay great attention to the heat dissipation of the product, especially for some parts (such as insulator).
If the components work under high temperature for a long time, they are easy to be damaged, and then cause fire or electric shock hazard. The power module inside the luminaire is in a small closed space, and the heat dissipation is restricted. Therefore, when the manufacturer selects the components, the brand of LED line light should pay attention to the selection of appropriate component specifications to ensure that the components work under a certain margin, and then avoid overheating when the components work close to the full load for a long time.
When the LED wall washing lamp is produced and delivered from the factory, it is necessary to conduct an aging test for about 24 hours for the LED wall washing lamp. After the aging test, the waterproof test shall be conducted immediately.
