Abstract

An optoelectronic component (1) comprises a carrier (2) and at least one semiconductor chip (3). The semiconductor chip (3) is arranged on the carrier (2) and equipped to emit a primary radiation (6). The semiconductor chip (3) is enclosed at least partially by an at least partially transparent medium (7) having a height (8) above the carrier (2) and a width (9) along the carrier (2). Particles (10, 11) that interact with the primary radiation (6) are introduced into the medium (7). The medium (7) has a ratio of height (8) to width (9) of more than 1.

Description

technical field [0001] The invention relates to an optoelectronic component having a semiconductor chip for emitting electromagnetic radiation, and to a lighting arrangement having at least one such optoelectronic component. Furthermore, a method for producing an optoelectronic component is proposed. Background technique [0002] Optoelectronic components and light-emitting devices having such optoelectronic components are known from the prior art. Document WO 2009 / 135620 A1 thus discloses a lighting device having a lighting means emitting electromagnetic radiation. A refinement of the lighting means can be an optoelectronic component. The electromagnetic radiation is partly deflected and partly changed in relation to its wavelength by the interaction with the particles. The deflection of electromagnetic radiation can be achieved by gradients in particle density. However, the adjustment of the particle density gradient is extremely complex, difficult to reproduce and exp...
