At this year’s light+building the German manufacturer FSIGN presented ‘one.LED’, a new lighting family which particularly takes advantage of the low construction height the FSIGN[LED]technology permits. The lamps consist of an accordingly bent alucubond body, in which the LED modules are planar embedded. The aluminium plays a major part in the thermal management by transporting the heat to the ambience.
Core of this technology is a 1/4 watt multichip LED with a minimum of heat generation.
The LED exists of three blue emitting semiconductor chips and a yellow photoluminescent overlayer which transforms light into a pleasant warm white of 3000K, the colour temperature of a halogen bulb.
Homogeneity of luminosity and colour temperature as well as colour rendering index CRI > 80 is guaranteed by using preselected LEDs.
