Abstract
A lighting device and a method for producing a lighting device are disclosed. In an embodiment, the lighting device includes a carrier, at least one optoelectronic illuminant arranged on the carrier, the illuminant configured to emit light into an emission area and a color scattering layer located in the emission area, the color scattering layer configured to generate a color by scattering of light at a surface of the color scattering layer facing away from the illuminant.
Claims8
A lighting device comprising:
- a carrier;
- at least one optoelectronic illuminant arranged on the carrier, the illuminant configured to emit light into an emission area;
- a further electronic component arranged on the carrier, wherein the further electronic component is a protective diode or a temperature sensor;
- and
- a color scattering layer located in the emission area, the color scattering layer configured to generate a color by scattering of light at a surface of the color scattering layer facing away from the illuminant,
- wherein the illuminant comprises a sprayed-on conversion layer, on which the color scattering layer is directly sprayed, and
- wherein the color scattering layer is directly sprayed onto the further electronic component and
- onto an area of the carrier that is situated between the illuminant and the further electronic component.
