Recently, Sharp has developed the second generation of its 10W Mini Zeni white-light LED arrays, featuring 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.

According to the company, it 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.

The new variants have a long service life of 40,000 operating hours at an operating temperature of up to 90°C. It 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’).

The new LED arrays can be available in spot lighting and LED retrofit lamps.
