1,The structure of washing wall lamp:
The power module of LED washing lamp install of external shell,the space is limited,some manufacturers in order save-space 。the dip component replace by the surface component 。this method is not acceptable。The surface welding pin type component is likely to fall off due to weak weld,so for these components as far as possible to take dip package。If has been surface component please use the glue fixed。
2,The test of washing wall lamp
1)Temperature rise test
Temperature test is necessarily project of products safety test,
different standard component has temperature limit。In the product design stage,the manufacturer should attach great importance to the problem of heat dissipation products, especially for some parts (such as insulating sheet etc.) special attention should be paid to。If the long-term work in the condition of high temperature,easy to damage, resulting in a fire or electric shock hazard.The power supply module inside the lamp in a closed small space, heat limited. Therefore, when the manufacturers choice the components,should pay attention to choose the appropriate components according with product specification, ensure the components working in a right range, thus avoiding the components to work close to full load under the condition to produce heat。
2)The aging test
When The LED wall washing lamp production is finish ,the need for LED wall washing lamp for about 24 hours aging test, after aging test should be tested for water resistance at once!
