new Ostar LED module from Osram has four or six
series-connected chips in a hexagonal shape that allows for high packing
Producing 420 lumens at an operating current of 700mA, the
six-chip version with an in-built lens is brighter than a 20W low-voltage
halogen lamp. LEDs are therefore now suitable for use in more and more general
For example, they can provide enough light now for a desk lamp
or a pocket video projector such as the new models from Samsung and Toshiba.
A specially developed hemispherical lens is part of the
standard equipment. This lens improves the efficiency with which light is
emitted without affecting the beam characteristics.
