Spring City™

Thermal Efficiency

Spring City’s LED system manages heat through an innovative technology that does not interfere with the integrity of our luminaire design.  Our patent pending CoolCast^TM heat dissipation allows our fixture to maintain a low junction temperature by dissipating heat through our cast aluminum hood directly to the atmosphere.  Assuming an ambient temperature of 25° C, our CoolCast^TM system will maintain a junction temperature of 60° C.

“Heat management and an awareness of the operating environment are critical considerations to the design and application of LED luminaires for general illumination. Successful products will use superior heat sink designs to dissipate heat, and minimize Junction Temperature.  Keeping the Junction Temperature as low as possible and within a manufacturer specification is necessary in order to maximize the performance potential of LEDs.”  US Department of Energy
