LED-BASED LIGHTING DEVICE WITH ASYMMETRICALLY DISTRIBUTED LED CHIPS

摘要

A lighting device (200a) is provided that allows a reduced color separation. The lighting device is configured to emit light along an output direction. The lighting device comprises a base (210), one or more light emitting diode, LED, chips (221) and a light transmissive dielectric material. The one or more LED chips are asymmetrically distributed on the base and are configured to emit light in the output direction. The light transmissive dielectric material may be embedding the one or more chips and includes luminescent material. A first chip of the one or more LED chips is arranged so that one corner of the first chip coincides, or at least closely, coincides with a central axis (290) of the lighting device.
