Abstract

A light generating device, comprising: at least one light emitting diode having a semiconductor layer that emits a first primary light, and having a phosphor layer arranged on the semiconductor layer, and at least one laser for generating at least one laser beam composed of a second primary light, by means of which the phosphor layer is irradiatable, wherein the phosphor layer is configured for at least partly converting the first primary light into at least one first secondary light and for at least partly converting the second primary light into at least one second secondary light. The light generating device is configured to dynamically illuminate the phosphor layer by means of the second primary light.
