SemiLEDs launches C35 LED featuring Color-Precision technology

July 17, 2012 // By Christoph Hammerschmidt
SemiLEDs Corporation unveiled its new C35 LED emitter incorporating the new Enhanced Vertical (EVTM) LED chip. It features narrow binning, low thermal resistance and a special optical design.

The C35 is SemiLEDs' first series of products to feature new Color-Precision technology, which will offer customers greater flexibility when making color choices. The C35 can yield consistent color within a single 7-step, 4-step or 2-step MacAdam ellipse centered in ANSI defined standard color spaces. 

In addition, the C35 utilizes a ceramic submount which gives it low thermal resistance (Rth <8°C/W). Lower thermal resistance allows heat to be effectively driven from an LED's junction, both extending the lifetime of the LED and providing better light quality, and reliability. Luminaires will experience more stable lumen maintenance and consistent correlated color temperature (CCT) over time due to the C35 advantages in thermal management, making it ideal for general lighting applications. 

Another key feature of the C35 is the special optical design that makes it easy to integrate with secondary optics. This design ensures light is distributed uniformly across the beam and diminishes the “yellow ring” effect typically found in white LEDs.
