Abstract

A media exposure device suitable for directly exposing a medium to radiation emitted from the device comprises a plurality of radiating members 12, each including a set of radiating elements 26, the radiating elements 26 being spaced in a predetermined pattern and each radiating member 12 being fixed in relation to at least one other radiating member 12 to form a continuous set of radiating elements 26 wherein the radiating elements 26 are each in the form of a plurality of LEDs arranged to form a cluster. Preferably the LEDs are micro LEDs arranged in a circular cluster; the device may include reflectors and a lens or micro lens array. Media exposure devices including: a mounting structure; a radiation modification means; and a plurality of organic LEDs are also disclosed.
