Sharp launches 2nd generation of 10W Mini Zeni LED arrays

Sharp has launched the second generation of its 10W Mini Zeni white-light LED arrays, which have 47% higher luminous efficacy of up to 106lm/W in standard operation, greater luminous flux of up to 900lm, and a (typical) color rendering index (CRI) of 82.

The firm says that technical advances in LED production have yielded four distinguishing features: they are compact, lightweight, economical and significantly brighter than before.

Sharp has retained the 15mm x 12mm x 1.6mm dimensions, along with an aluminium ceramic plate as carrier material. The flat surface of the ceramic plate and the existing soldering points make it possible to attach the modules to a suitable heat sink, without too much effort or additional connecting material, it is claimed, achieving efficient heat dissipation.

Depending on the module, the new variants have a long service life of 40,000 operating hours at an operating temperature of up to 90°C. The new generation is specified for use with a forward voltage of 17.7V and a forward current of 480mA, but the arrays can also be operated using a current of up to 800mA, yielding output of up to 1300lm. Colour temperatures are 3000-5000K (‘Natural White’, ‘Warm White’ and ‘Pure White’).

Sharp says that its extensive range of LED lighting arrays allows it to provide numerous marketable solutions for the use of LEDs as light sources for lamps and lighting fixtures. The Mini Zeni modules suit applications including spot lighting and LED retrofit lamps.

Initial samples are available (via Sharp’s sales offices and distribution partners across Europe) with colour temperatures of 3000 and 4000K.
