Spring Citys LED system manages heat through an innovative technology that does not interfere with the integrity of our luminaire design. The patented CoolCastTM heat dissipation technology allows the luminaire to maintain a low junction temperature by dissipating heat through the cast aluminum hood directly to the atmosphere. Assuming an ambient temperature of 25 C, theCoolCastTM 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
