Abstract:
A lighting apparatus may include a light generating device for generating a primary light beam, a phosphor body that can be irradiated by means of the primary light beam and serves for partly converting primary light of the primary light beam into secondary light, and a spectral filter disposed downstream of the phosphor body. The spectral filter may be more highly transmissive to the secondary light than to the primary light where the spectral filter is arranged along a beam axis of the primary light beam incident on the phosphor body. The lighting apparatus may be used in LARP arrangement for vehicle lighting, general lighting, exterior lighting, stage lighting, effect lighting, etc.
