How are the wall washers routinely tested when they leave the factory?

2022-01-07


Temperature rise test is a must-do item for product safety testing. The standard has certain temperature rise restrictions on different components. In the product design stage, manufacturers should pay great attention to the heat dissipation of the product, especially for certain parts (such as insulating sheets, etc.).

If the parts work under high temperature conditions for a long time, they are easy to be damaged, which may cause fire or electric shock. The power module inside the luminaire is in a closed and small space, and the heat dissipation is limited. Therefore, when selecting components, manufacturers should pay attention to selecting appropriate component specifications to ensure that the components work with a certain margin, so as to avoid overheating caused by long-term operation of the components near full load.

Aging test

When the LED wall washer is produced and shipped, the LED wall washer needs to be subjected to an aging test for about 24 hours, and the waterproof test should be carried out immediately after the aging test.

water-proof test

The waterproof test should be a test item to be carried out immediately after the aging test. In this way, the real IP protection level of the LED wall washer can be tested by simulating the real environment. This method is generally called thermal test. After the lamp glows and heats, the lamp will expand and contract. Only at this time can the test really test whether the LED wall washer is competent in the harsh outdoor environment and ensure the lamp There is no problem with its waterproof and dustproof ability under the conditions of wind, rain and sun.

Failure test

Failure test is a crucial test item in product certification test. This test item is to short-circuit or open some components on the line to simulate the failure that may occur during actual use, so as to evaluate the safety of the product under a single failure condition. In order to meet this safety requirement, during product design, it is necessary to consider adding a suitable fuse to the input of the product to prevent the occurrence of overcurrent when the output is short-circuited or internal component failure, which may cause a fire hazard.
