Illumination device with led and a transmissive support comprising a luminescent material |
| abstract |
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. |
