Abstract:
In at least one embodiment, a surface light source includes one or a more optoelectronic semiconductor chips having a radiation main side for generating a primary radiation. A scattering body is disposed downstream of the radiation main side along a main emission direction of the semiconductor chips. The scatting body is designed for scattering the primary radiation. A main emission direction of the scattering body is oriented obliquely with respect to the main emission direction of the semiconductor chip.
