ILLUMINATION DEVICE WITH LED AND A TRANSMISSIVE SUPPORT COMPRISING A LUMINESCENT MATERIAL

The invention provides an illumination device (10) with a light emitting diode (20), a transmissive support (50) comprising a luminescent material (51), and a translucent exit window (60). The ratio of the diffuser cavity cross section (212) and LED cavity cross section (211) is larger than (1). Wit...

description The invention provides an illumination device (10) with a light emitting diode (20), a transmissive support (50) comprising a luminescent material (51), and a translucent exit window (60). The ratio of the diffuser cavity cross section (212) and LED cavity cross section (211) is larger than (1). With the proposed illumination device (10), the lamp may in particular look white when it is in the off-state and illuminated with white light. Other advantages are that an intrinsically efficient system may be provided and that a warm white option may be provided.
