Abstract (en)
[origin: WO2009132833A2] An LED module comprises at least one LED chip (4) emitting monochromatic light having a first spectrum, a platform (2) on which the LED chip is mounted, a reflecting wall (9) that is separate from or integrated into the platform and surrounds the LED chip on all sides, and a dispensed layer (11) applied above the LED chip. The dispensed layer extends in a dome-shaped manner beyond the reflecting wall such that the following equation is satisfied: 0.1*b 1 = h 1 = 0.5*b 1 , where h 1 is the height of the dome-shaped dispensed layer, measured from the topmost point of the reflecting wall to the apex of the dome, and b 1 is the diameter of the depression formed by the reflecting wall, measured as the distance from the central axis of the wall.
