With the Zenigata Line-Up, Sharp Introduces a New Series of High-Power LED

Sharp, at Electronica 2008, sets new standards for LEDs for lighting purposes. Right on time for electronica, the Japanese company introduces a new series of high-power LED modules for lighting purposes.

With a lighting performance of up to 540 lumens, the new “Zenigata” modules make a direct leap into the category of the 60W equivalent lamps with a power consumption of only 6.7 watts. Thanks to the light yield of up to 80 lumens per watt (depending on the module), the LEDs from Sharp are amongst the front-runners today in the field of energy efficiency in LED lamps. In addition to their superb energy efficiency, 40,000 operating hours at an operating temperature of 80°C also ensure that the overall system costs stay low, thanks to the long maintenance intervals of the respective lighting application.

Divided into sixteen parallel-switched series of three, the modules of the 540 lumen series are built up in a matrix of 48 LED dyes that provide an overall light output of between 350 and 540 lumens, depending on the module. In contrast, the LED modules of the 280 lumen series consist of ten parallel-switched series of three with a total of 30 LED dyes. They provide a light output of 190 to 280 lumens. For both series (540 and 280 lumens), an aluminium-ceramic plate measuring 18 x 18 x 1.5 millimetres is used as a substrate. Already equipped with mounting drill holes make it possible to fix the modules securely to a suitable cooling element without great effort.

The colour temperature of the white light LED lighting module from Sharp lies within a range of 2,800 to 6,500 kelvins with the defining tones of “normal white light”, “warm white light”, comparable to a light bulb and two types of “high colour rendering white”. By means of two slightly varying phosphorus compounds, “high colour rendering” LEDs attain a CRI value of 90 and thus provide high colour veracity and detail fidelity. This is of decisive importance everywhere where artificial light ought not to distort the depiction of the illuminated objects. “High colour rendering” LED modules are therefore in demand in areas such as photography, display window decoration and goods presentation, as well as in medical technology, e.g. for surgery lights.

The powerful LED light modules from Sharp are generally suitable for numerous applications: in interior rooms, e.g. for study, reading and desk lamps, decorative lighting, direct and indirect lighting for work surfaces in kitchens etc., as spotlights for stages and building sites or as components for LED large displays. The LED modules are also a long-lasting solution for reading lamps on public transport such as trains, aeroplanes and buses. The high-power modules of the 540 lumen series are in particular used in so-called retrofit lamps. These can directly replace conventional electric incandescent lamps so that the consumer can profit directly from the high energy efficiency of the Sharp LED modules in the future.
