Embodiment Construction
[0011] In the figures, identical or functionally identical components are provided with the same reference symbols.
[0012] figure 1 The embodiment of the lighting device depicted in includes a light source 1 which can be formed, for example, as a semiconductor laser, in particular as a laser diode grid. At least partially not shown optical devices, such as fast-axis lenses and slow-axis lenses, etc., can be arranged behind the light source 1 in the direction of propagation.
[0013] The lighting device furthermore comprises a homogenization device 2 comprised by said optics, which in the depicted embodiment has two lens arrays 3, 4 which enable the light source 1 to The light 5 is homogenized. There is also the possibility of providing additional homogenization means, for example rectangular waveguides or diffractive optical elements (DOEs).
[0014] A Fourier lens 6 arranged downstream of the homogenization device 2 and comprised by the optical device superimposes the pa...
