LIGHTGUIDE PHOTOTHERAPY APPARATUS
First Claim
1. An apparatus for directing electromagnetic radiation into a respective pupil of at least one eye of a user, the apparatus comprising:
- first radiation emitting means comprising at least one radiation emitting layer adapted to emit electromagnetic radiation;
second radiation emitting means adapted to direct electromagnetic radiation into at least one eye and/or onto at least one eyelid of a user; and
radiation guide means adapted to receive radiation emitted by said first radiation emitting means and to direct at least part of said radiation to said second radiation emitting means, wherein a total surface area of said first emitting radiation means from which radiation is emitted is larger than a total cross sectional area of a beam of radiation entering the or each pupil of the user in use, in a direction transverse to an optical axis of said beam.

Abstract
An apparatus (20) for directing electromagnetic radiation into a respective pupil of at least one eye of a user is disclosed. The apparatus comprises first radiation emitting means comprising at least one radiation emitting layer (8) adapted to emit electromagnetic radiation and second radiation emitting means (6} adapted to direct electromagnetic radiation into at least one eye and/or onto at least one eyelid of a user. A light guide (1) is adapted to receive radiation emitted by the first radiation emitting means and to direct at least part of the radiation to the second radiation emitting means, wherein a total surface area of the first emitting radiation means from which radiation is emitted is larger than a total cross sectional area of a beam of radiation entering the or each pupil of the user in use, in a direction transverse to an optical axis of the beam.
