Sharp Updates and Expands Their Popular Natural Toning Zenigata LEDs

Sharp Devices Europe (SDE) has launched the second generation of its Natural Toning Zenigata COB LEDs, which warm as they are dimmed. The new models offer an expanded CCT range and enhanced energy efficiency.

Available in the popular Mini Zenigata footprint, Natural Toning technology automatically tunes the colour temperature from 3000K down to as low as 1900K as the LED is dimmed. This mimics the behaviour of conventional incandescent sources, which is desirable for instance in hospitality and retail applications. Natural Toning Zenigata COBs require no special control electronics; a standard amplitude-dimming driver is all that’s required, making them easy to integrate and simple to operate.

Outstanding colour quality:

Natural Toning LEDs from Sharp provide outstanding colour quality, with typical CRIs ranging between 92 and 94 across the dimming range. Warm white and cool white blocks are combined within a single light emitting surface, ensuring uniform colour distribution without the complexity of RGB-array solutions. The spectral fidelity and colour gamut of Natural Toning COBs results in a nearperfect reproduction of halogen lamp behaviour.

Toning things down:

The positive reception that the first generation of Natural Toning LEDs experienced has allowed Sharp Devices Europe to gather feedback on customer preferences. In response, the colour range of second-generation Natural Toning COB LEDs was adjusted accordingly. After the modification, the warm end is warmer, with output now ranging from 1900 K to 3000 K. Efficiency has increased to more than 90 lumens per watt. There is also a new model with a 6 mm LES that produces a very narrow light beam.

Availability:

Second-generation Natural Toning Mini Zenigata LEDs are available immediately. Thanks to their single drive circuit with just one pair of terminals, they reduce design complexity and installation costs for dim-to-warm applications.
