LED Lighting Modules Deliver High Efficiency and Long Life

Four new LED lighting modules from Sharp deliver a lighting efficiency of up to 80 lumens per watt. A lifetime of 40,000 hours at an operating temperature of +80°C ensures that overall system costs stay low, thanks to the resulting long maintenance intervals.



The modules are structured in a matrix of 30 LED chips divided into ten, parallel, switched series of three, providing a lighting performance of between 170 lumens and 280 lumens. An aluminium ceramic plate of 18mm x 18mm x 1.5mm is used as substrate material. Equipped with pre-drilled mounting holes, the modules can be simply and securely fixed to a suitable cooling element.

The colour temperature of the four new modules lies within the range of 2,800 to 6,500 Kelvins; the shades ‘normal white light’ and ‘warm white light’ are comparable to an incandescent light bulb, the other two shades are in the area ‘High Colour Rendering (HCR) white’.

Through two slightly different phosphorous mixtures, the two HCR LEDs reach a Colour Rendering Index (CRI) value of 90 and thus ensure high colour fastness and attention to detail. This is important in applications where artificial light must not distort the depiction of illuminated objects. HCR modules are therefore in demand in areas such as photography, shop window decoration and goods presentation, as well as in medical technology, for example for surgical lamps.

The powerful LED-light modules from Sharp are generally suitable for a host of other applications: in interior lighting, for example for study, reading and desk lamps; decorative lighting; direct and indirect lighting for work surfaces in kitchens; as spotlights for stages and building sites or as components for large LED displays. The LED modules are also a long-lasting solution for reading lamps on public transport such as trains, aeroplanes and buses.
