Sharp unveils multi-chip LED lighting modules

Sharp Microelectronics Europe of Hamburg, Germany has introduced four new LED lighting modules, reports LEDs Magazine. The Sharp LEDs have a lighting efficiency of up to 80 lumens per watt depending on the module.

The Sharp LED modules also boast 40,000 hours operating time 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 ten parallel-switched series of three, the modules are structured in a matrix of 30 LED chips that provide a lighting performance of between 170 and 280 lumens, depending on the module.

An aluminum ceramic plate of 18 x 18 x 1.5 mm is used as substrate material. Already equipped with mounting drill holes the modules can be securely fixed to a suitable cooling element without great effort.

The color temperature of the four white light LED lighting modules from Sharp lies within the range of 2,800 to 6,500 Kelvins with the shades ‘normal white light’, ‘warm white light’, comparable to a light bulb and two shades in the area ‘High Color Rendering white’.

Through two slightly different phosphor mixtures, the two ‘High Color Rendering’ LEDs reach a CRI value of 90 and thus ensure high color fastness and attention to detail. This is of decisive importance everywhere where artificial light should not distort the depiction of the illuminated objects.
