摘要

The lighting-device (1) has two phosphor regions (3a, 3b) that are individually illuminatable by respective light sources, where the light sources are designed as narrow beam light sources i.e. blue lasers (2a, 2b). The lasers are designed as solid state lasers or laser diodes. The phosphor regions are aligned for partially converting wavelength of incident light, and for diffuse radiation of the light on downstream optical elements i.e. reflectors (5a, 5b), where the optical elements exhibit different optical properties. The phosphor regions are mounted on a cooling body (6).
