LIGHT OUTPUT DEVICE

摘要

A light output device comprises a light transmissive substrate arrangement comprising first and second light transmissive substrates (1, 2). At least one light source device (4) is integrated into the structure of the substrate arrangement between the substrates, and an electrode arrangement (7a, 7b) is formed on one of the substrates and between the substrates, with the- light source device or devices connected to the electrode arrangement. The light source device or devices (4) each comprise a semiconductor device (4a), formed in a substantially transparent light source device package (4b), and the light source device package (s) are embedded into a substantially transparent material layer (5) between the substrates. This arrangement enables the device to have a substantially uniform visual appearance when turned off, and this is considered desirable by users in many different applications.
