Abstract:
A light output device comprises at least one light source having a light source output comprising at least a light output, and a switchable member through which the light output is provided, and which is switchable between at least two optical states. These at least two optical states provide different levels of uniformity of the light output. The switching of the switchable member is induced by the light source output.
