Sharp LEDs meet the needs of demanding lighting applications

Sharp Microelectronics of the Americas (SMA) unveiled two LED product families recently, the Double Dome and the Mini Zenigata. The families offer a range of features, sizes, and outputs to match the needs of demanding lighting applications. The products combine a blue LED die with a proprietary mixture of green and red phosphors to achieve high reliability and low heat dissipation.

The Double Dome delivers up to 54 lm in a 2.8- by 2.8-mm package. These LEDs offer CRI performance that exceeds most fluorescent solutions, while also maintaining competitive efficacy and cost-per-lumen performance. Suitable applications include indoor and outdoor lighting; architectural illumination; and channel letter solutions.

The Mini Zenigata LEDs require about half (56%) the surface area of previous models and offer a reduction in the emissive area when compared to the company's Zenigata offering. Mini Zenigata modules offer chromaticity performance tighter than that defined by existing ANSI CCT standards (under 3 Macadam ellipse). In addition, the modules attach directly to a heat sink and “drop-in” easily into lighting fixtures and equipment due to their small footprint.

A Mini Zenigata module fitted into an MR-16 fixture (multi-faceted reflector, silver background) creates a high-intensity light suited for showcases, rail lights, task lights, and similar applications. Modules operate at 3.6 or 6.7 W.
