LIGHT EMITTING DEVICE

摘要

A light emitting device comprises an electroluminescent element (1), a housing (2) and current supply means for the electroluminescent element. It is characterized by a micro-optical element (12) being coupled to the housing (2) and being arranged in a manner that it influences light emitted by the electroluminescent element (1). The micro-optical element may be made up of micro-optical structures on a surface of an at least partially transparent layer (11) coupled to the housing (2). The micro-optical structures may for example be manufactured by directly imprinting them on the at least partially transparent layer (11) coupled to the housing or by casting an at least partially transparent layer (11) comprising the electroluminescent element to a body of the light emitting device. The diffractive optical features of the micro-optical element (12) are designed according to the position, size and shape of the one or more electroluminescent elements (1), and output light distribution of the one or more electroluminescent elements (1).
