1 min read
Sharp has introduced the second generation of its 10W Mini Zeni variant, which radiates with an efficacy of up to 106lm/W, with a luminous flux of up to 900lm and is available with a typical CRI value of 82.
According to Sharp, the latest version of the led arrays have improved efficiency of up to 47%, are compact, lightweight, economical and significantly brighter than before.
The company has retained the dimensions of 15 x 12 x 1.6mm, along with an aluminium ceramic plate as carrier material, while the flat surface of the ceramic plate and the soldering points already in place make it possible to attach the modules to a suitable heat sink.
Depending on the module, the new types offer a light output of up to 900lm, a luminous efficacy of up to 106lm/W in standard operation, CRI values of 82 and a 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. The arrays can also be operated using a current of up to 800mA, where, according to Sharp, values of up to 1300lm can be reached. With the shades 'Natural White', 'Warm White' and 'Pure White', the colour temperatures of the new white light led arrays are in the range of 3000 to 5000 Kelvin.
The Mini Zeni led modules are suitable for applications such as spot lighting and for use in led retrofit lamps.
