Abstract (en)
The lamp (10) has a light source (15) arranged in a housing (11), and a light emitting opening (23). A diffuser unit (18) in the light path is arranged between the light source and the light emitting opening. The diffuser unit comprises two ranges with different transmission characteristics for generating two different light cones. One of the ranges surrounds the other range in a circular form. Ratio of the diameter or the width of one of the ranges to the overall diameter or entire width of the diffuser unit is between 1/5 and 2/3.
