LIGHT EMITTING DIODE

摘要

A semiconductor light emitting diode (1) comprises a first and a second electrode for applying a voltage across an active region (4) for generation of light, and a light emitting surface (6) for emitting the light. The LED further comprises a first and a second light guiding means (201, 202, 203). Furthermore, a first sub-electrode (41, 42, 43, 44, 45) is associated with the first light guiding means (201, 202, 203) and a second sub-electrode (41, 42, 43, 44, 45) is associated with the second light guiding means (201, 202, 203). The first and second sub-electrodes (41, 42, 43, 44, 45) are individually controllable by means of applying a respective voltage to each of the first and second sub-electrodes (41, 42, 43, 44, 45).
