SemiLEDs launches C35 Enhanced Vertical LED featuring Color-Precision technology

LED chip and component maker SemiLEDs Corp of Hsinchu Science Park, Taiwan has launched its C35 LED emitter, which incorporates the firm’s new Enhanced Vertical (EV) LED chip (unveiled at the end of June). The new LED 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 offers 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 uses 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’s advantages in thermal management, SemiLEDs reckons, suiting general lighting applications.

Another key feature is the special optical design, which makes it easy to integrate with secondary optics, the firm adds. The design ensures that light is distributed uniformly across the beam and diminishes the ‘yellow ring’ effect typically found in white LEDs, it is claimed.
