Q:What problems should we pay attention to in the maintenance of LED lamps?

     A:1. The high-power LED of Keresi or Osram used in our lighting selection is made of transparent soft silica gel. In the process of transportation and maintenance, the LED lens is absolutely not allowed to be squeezed, otherwise it may cause damage to the light-emitting chip inside.
2. In the process of transportation and maintenance, it is not allowed to touch the LED lens directly with your hands, because there is grease on your hands. Once you touch the lens, a thin oil film will be formed, which will affect the luminescence, and the oil film can never be removed.
3.LED is a high heating components, LED heat dissipation is a good ring, the most decisive influence on the life of LED lamps, LED heat, from the heat transfer channel in the figure above, we can know that eventually through the heat dissipation aluminum material (shell) to the outside air.
4 products, in the design of aluminum plate and shell contact, will be pressed close to, but on the microstructure, these look very smooth surface, is uneven, the actual contact, are all contacts, in the vast majority is void, and the air is bad body heat conduction, so all the LED lamps and lanterns in aluminum plate and heat between the shell, Coat with a thin layer of a highly conductive incubator called "thermal silicone" (gray or white). The heat of the LED can be transmitted to the heat dissipation shell through the heat conduction silicone grease, and then scattered to the air.
5. When repairing and replacing LED aluminum substrate components, it must be at the bottom of the aluminum substrate, especially the bottom position of the LED, coated with a thin layer of thermal conductive silicone grease, the thickness is about 0.2mm (equivalent to the thickness of 2 pieces of white paper), the thicker the better. LED aluminum substrate components without coating thermal conductivity silicone grease, due to poor heat dissipation, LED lamp beads will be in a few days to a few months from a sharp light decline, until the LED burned out.
6. The same requirement applies to the replacement of LED aluminum substrate components for mobile products.
7. The factory will uniformly distribute small barrels of heat-conducting silicone grease to each service department for maintenance and replacement of LED aluminum substrate components.
