  • TL retrofit LED module outside sealed glass tube
    Patent number: 8878430
    Abstract: This invention relates to a lighting device comprising a light generation unit (102), which comprises a light emitting diode element (105) having at least one light emitting diode (103), and a light conversion unit (104). The light conversion unit comprises an integral enclosure (110), which encloses a cavity (130), and an organic phosphor element (112) arranged within the cavity. The light generation unit further comprises a base part (114), which includes a thermally conductive material (114) thermally connected with the light emitting diode element. Light generated by the light emitting diode element of the light generation unit is output through the light conversion unit and thereby converted by the organic phosphor element.
