发明名称 Luminescent-OLED light collector signage panel
摘要 The invention provides a light collector (1) comprising a luminescent material (20) element, a discontinuous semi-transparent layer (40) adjacent to a first side of the luminescent material element (20), wherein due to the discontinuity of the semi-transparent layer (40) at least one first portion (21) of the luminescent material element (20) covered by the semi-transparent layer (40) and at least one second portion (21) of the luminescent material (20) element not covered by the semi-transparent layer (40) are formed, and a light generating means (10) arranged at a second side of the luminescent material element (20). Further, a method for concentrating light in a light collector (1) is provided, comprising the following method steps: capturing light from the environment by means of a luminescent material (20), concentrating the light in the luminescent material (20) by means of a semi-transparent layer (40) arranged on the luminescent material (20) and light generating means (10), emitting the light in a pre-determined area of the light collector (1) by means of an out-coupling structure (30) so as to generate a pre-determined light emitting image.
