Large aluminum PCB plate raidator aluminium extrusion profile heat sink for cxb3590 led grow light

 Thermal performance

A main cause of LED Light failures is improper thermal management. Many performance characteristics of LED components are influenced by the operating temperature, so LED system designers need a basic understanding of thermal design and performance. All Renxin.Thermal Heatsink product datasheets detail the performance characteristics  that  are impacted by temperature  Also,  Renxin.Thermal  internally Test and developed CFD software, the Heatsink Rth and thermal solutions , can be used to calculate the specific responses to thermal effects. Some performance characteristics experience a recoverable change, such as light output, color and voltage, while others, such as lifetime, can experience a non-recoverable degradation due to high operating temperatures. However, exceeding the maximum operating temperature specification, which is typically a 150 °C junction temperature, can cause permanent and/or catastrophic damage to LEDs, so care must be taken to operate LEDs below this limit.
