Popularization of High-power LEDs Brings New Upgrading Challenges to Thermal Grease
In recent years, LED lighting has developed rapidly towards high power output. The power of industrial floodlights, outdoor spotlights and special lighting products generally ranges from 200W to 500W, and some special lighting exceeds 1000W. High-power LED beads generate massive heat during operation. Poor heat dissipation will accelerate luminous decay and shorten service life, which puts forward higher requirements for thermal grease performance.
Traditional thermal grease with thermal conductivity below 3W/(m·K) can no longer meet heat dissipation demands of high-power LEDs. It fails to effectively control bead temperature and easily causes overheating and luminous efficiency decline. To solve this problem, manufacturers have developed dedicated thermal grease for high-power LEDs by optimizing base gel formula and increasing the proportion of high thermal conductive fillers, achieving a substantial improvement in heat conduction capacity.
Practical tests prove that when applied in 300W lamps, the new-generation special thermal grease reduces LED bead temperature by over 18℃ and slows down luminous decay by 30%, greatly extending lamp service life. Meanwhile, optimized viscosity makes it suitable for automated coating processes, fully catering to large-scale production needs, and driving the LED lighting industry toward higher power and longer service life.
