About the test method of LED wall washer
The power module of the LED wall washer is installed inside the casing, and the space is limited. Some manufacturers can solder the surface of the pin-type component to the PCB in order to save space. This is unacceptable. These surface-welded pin-type components are likely to fall off due to soldering or the like, posing a hazard. Therefore, it is necessary to adopt a jack welding method for these components. If the surface welding method has to be used, it is necessary to provide additional protection for the component by means of glue fixing.
The temperature rise test is a mandatory item for product safety testing. The standard has certain temperature rise limits for different components. In the product design phase, manufacturers should pay great attention to the heat dissipation of the product, especially for certain components (such as insulation sheets).
Parts that work under high temperature conditions for a long period of time are prone to damage, posing a fire or electric shock hazard. The power module inside the luminaire is in a tight space and the heat dissipation is limited. Therefore, when selecting components for the manufacturer, it is necessary to pay attention to selecting the specifications of the appropriate components to ensure that the components work under a certain margin, so as to avoid overheating due to the long-term operation of the components under conditions close to full load.
When the LED wall washer is manufactured, it is necessary to carry out the aging test on the LED wall washer for about 24 hours. After the aging test, the waterproof test should be carried out immediately!
The waterproof test should be a test project that is carried out immediately after the aging test. In this way, we can simulate the real environment to test the true IP protection level of the LED wall washer. This method is generally called thermal testing! After the luminaire glows, the luminaire will have a phenomenon of thermal expansion and contraction. At this time, the test can truly test whether the LED wall washer can be used in the harsh outdoor environment! Shenzhen Jingruide LED wall washers all use the thermal test method to test their LED wall washers to ensure that the lamps have no problem in waterproof and dustproof capacity under the conditions of wind, rain and sun exposure. Product failure testing is a critical test item in product certification testing. This test item is to short-circuit or open some components on the line to simulate the failures that may occur during actual use to evaluate the safety of the product under a single fault condition. In order to meet this safety requirement, in the product design, it is necessary to consider adding a suitable fuse at the input end of the product to prevent overcurrent from occurring when the output is short-circuited or the internal component fails, resulting in a fire hazard.
