In LED lamps, large plastic profiles are commonly used in components such as enclosures and heat dissipation brackets, and their performance directly affects the service life and safety of LED lamps. In practical applications, profiles are prone to problems such as insufficient heat dissipation and poor weather resistance.
Common Issue 1: Poor heat dissipation performance of large plastic profiles in LED lamps leads to rapid lumen depreciation of lamp beads. Solution: Select modified plastics with thermally conductive fillers, optimize the profile structure design, increase the area of heat dissipation fins, and improve air convection heat dissipation efficiency.
Common Issue 2: Profiles of outdoor LED lamps crack or discolor after long-term exposure to sunlight. Solution: Use plastic raw materials with anti-UV aging formulations, perform surface spraying or coating treatment to enhance the weather resistance of the profiles and extend their service life.
Common Issue 3: Poor installation adaptability of profiles, resulting in difficulty in assembling with LED modules. Solution: Strictly control profile tolerances during the precision extrusion stage, adopt modular design, reserve standardized installation interfaces, and improve assembly efficiency.
