摘要: An optoelectronic component is described, comprising a semiconductor body that emits electromagnetic radiation of a first wavelength when the optoelectronic component is in operation, and a separate optical element disposed spacedly downstream of the semiconductor body in its radiation direction. The optical element comprises at least one first wavelength conversion material that converts radiation of the first wavelength to radiation of a second wavelength different from the first.

摘要: The invention concerns an LED arrangement with at least one LED chip comprising a radiation decoupling surface through which the bulk of the electromagnetic radiation generated in the LED chip is decoupled. Arranged on the radiation decoupling surface is at least one phosphor layer for converting the electromagnetic radiation generated in the LED chip. A housing envelops portions of the LED chip and the phosphor layer.
