ILLUMINATION DEVICE WITH LED AND A TRANSMISSIVE SUPPORT COMPRISING A LUMINESCENT MATERIAL |
摘要 |
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 luminescent material (51) LED (20) distance dLL is larger than 0 mm, and the luminescent material (51) exit window (60) distance dLW is also larger than 0 mm. With the pro-posed illumination device (10) the lamp may especially 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. |
