Abstract
A lighting module has an LED (), a lens () over the LED to produce a beam-shaped output from the LED and a collimator () arranged to partially collimate the beam-shaped out-put. Blue light is provided at large angles to the normal, for example using a filter arrangement () over the collimator which is adapted to filter light from the collimator at relatively large angles to the normal. The filter arrangement does not filter light from the collimator at relatively small angles to the normal. Thus, the module provides white task light in a normal direction and blue ambient light at steep angles. The overall system can be compact and light efficient.
