Optical arrangement has transport mechanism that is formed to move optical functional area along emitting surface of radiation-emitting device, so that radiation characteristic of radiation exited over output surface is changed

摘要

The arrangement (100) has a radiation-emitting device (1) that is set with optical functional area (4a) which is transparent. The radiation characteristics of radiation exited from optical functional area on radiation exit surface (9) is set differ from radiation characteristics of radiation exited from radiation-emitting device on emitting surface (3). A transport mechanism (5) is formed to move optical functional area along emitting surface of radiation-emitting device, so that radiation characteristic of radiation exited over an output surface is changed.
