High Power LED Lighting Modules Shed More Light for Less Power

A new series of high-power LED modules for lighting purposes provides illumination levels of up to 540lm. With a power consumption of only 6.7W, the new Zenigata series brings LED technology into the category of 60W equivalent lamps.

Sharp says that a light yield of up to 80lm/W ranks the new series amongst the best performers in the field in terms of energy efficiency. The modules also exhibit excellent operating lifetime specifications of 40,000 hours at +80°C, reducing maintenance requirements and hence lifetime cost.

Divided into 16 parallel-switched series of three, the new modules consist of a matrix of 48 LED chips that provide an overall light output of between 350lm and 540lm. A complementary 190lm to 280lm series consists of 30 LED chips arranged as ten parallel-switched series of three.

For both series, an aluminium-ceramic plate measuring 18mm x 18mm x 1.5mm is used as a substrate. This is supplied ready-drilled with mounting holes, making it possible to fix the modules securely to a suitable cooling element quickly and simply.

The colour temperature of these white light LED lighting modules lies within a range of 2,800K to 6,500K. Four tones are available: normal, warm (comparable to a light bulb) and two types of High Colour Rendering (HCR).

By using two slightly different phosphorus compounds, the HCR LEDs attain a Colour Rendering Index (CRI) value of 90. They thus provide high colour veracity and detail fidelity – essential in applications where the use of artificial light must not distort image quality. HCR LED modules are therefore in demand in areas such as photography, display window decoration and goods presentation, as well as in medical technology, for instance for surgery lights.

Sharp’s LED light modules are generally suitable for a wide range of applications. These include interior illumination, for example in study, reading and desk lamps; decorative lighting; direct and indirect lighting, for instance for kitchen work surfaces; as spotlights for stages and building sites and as components for large LED displays. They are also a long-lasting solution for reading lamps on public transport such as trains, aeroplanes and buses.

The high-power modules of the 540lm series are particularly useful in retrofit situations when conventional incandescent lamps are directly replaced for the sake of lifetime cost and high energy efficiency.
