Definitions
- the invention relates to a light-generating arrangement comprising a light-emitting semiconductor element having electrical leads, as well as a transparent Lichtausrichtelement arranged in the emission direction in front of the semiconductor element, through which the light emitted from the semiconductor element is bün ⁇ delbar to a luminous flux.
- Semiconductor light emitting elements in particular high- ⁇ -performance LEDs usually have a Lambert radiation or a very large opening angle of the radiation.
- s primarily refractive and reflective secondary optics are recognized as Lichtausrichtelement ⁇ turned in the high-power LED '. These optics lead to a bundling of the luminous flux and to very high luminances in the forward direction.
- the object of the invention is therefore to provide a light-generating An ⁇ order of the aforementioned type which avoids the disadvantages mentioned and whose luminous flux is highly homogeneous and has no significant loss of brightness.
- the decoupling surface of the light-aligning element has a microstructure formed of a plurality of elevations and depressions, through which the beam paths of the luminous flux by an angle ⁇ 5 ° are deflected.
- Another solution of this object is achieved by having a microstructure formed levies of a plurality of elevations and Vertie ⁇ by the coupling surface to the output surface of the Lichtausrichtelements extending wall of the Lichtausrichtelements that of the reflection of the beam paths of the light flux on the wall Lichtaus ⁇ directing element by an angle ⁇ 5 ° are deflected.
- the individual beam paths of the directed light beams of the luminous flux are so easily changed that, although within the luminous flux, which can be a cone of light after Abstrah ⁇ ment, the light is redistributed. But this is so that essentially no light scatters back or is scattered out of the luminous flux or light cone.
- the light-aligning element may preferably be a converging lens.
- a high uniformity of the luminous flux is characterized ⁇ rich enough that the microstructure has a surface roughness of ⁇ 100 microns.
- the microstructure is formed on a transparent film, the buildin on the output surface by means of a refractive index-matched adhesive ⁇ is Untitled.
- microstructure is applied by means of the decoupling and / or the wall of the light ⁇ aligning resist is formed, whose free surface assumes the microstructure during curing.
- microstructure is formed by a plurality distributed on the outcoupling surface and / or on the wall of the alignment element arranged microlenses or microlens-like elevations.
- the elevations and depressions are preferably arranged distributed stochastisch.
- FIGURE of the drawing shows a schematic cross- sectional view of a light-generating arrangement.
- the illustrated light-generating arrangement has as a light-emitting semiconductor element a high-power LED (light emitting diode) 1, in front of which a light-aligning element 2 is arranged at a distance in the emission direction of the light.
- a high-power LED light emitting diode
- the secondary optics forming Lichtausrichtelement 2 is made of a transparent plastic as an injection molded part Herge ⁇ provides.
- the non-directional light emitted by the high-power LED is introduced into a coupling surface 3 of the light-directing element 2 in this and, inter alia, by a reflection at the wall 5 of the light-aligning element 2 extending from the coupling surface 3 to a coupling surface 4 of the Lichtausrichtelements 2 to a homogeneous and directed aligned at the outcoupling surface 4 emerging luminous flux.
- the decoupling surface 4 has a microstructure 6 of a plurality of uneven elevations and depressions, through which the beam paths of the aligned luminous flux are deflected at the exit from the Lichtausrichtelement 2 by an angle ⁇ 5 °.
- the microstructure 6 could also be arranged on the wall 5.
