Title: SEMICONDUCTOR LIGHT SOURCE
Abstract:
In one embodiment of the invention the semiconductor light source (1) comprises at least one first emission unit (21), a second emission unit (22) and an optical unit (3). The optical unit (3) has an inner region (31) for concentrating radiation from the first emission unit (21) and an outer region (32) for widening or scattering radiation from the second emission unit (22). When viewed from above, a first light-emitting region (41) of the inner region (31) fully covers the first emission unit (21) and covers at least part of the second emission unit (22). When viewed from above, a second light-emitting region (42) of the outer region (32) is located in part or fully next to the second emission unit (22). The inner region (31) and the outer region (32) have light-entry regions (51, 52) of differing forms.
