LOW-COST MOUNTING OF LEDS TO MODIFIED LUMINESCENT TUBES Russian patent published in 2016 - IPC F21K99/00 

FIELD: electricity.

SUBSTANCE: invention relates to lighting engineering. A lighting device comprises a translucent light-transmitting unit (102) and light-emitting diodes (LEDs) (104) that create the light emitted via the light-transmitting unit. The lighting device comprises a conductive laminated structure (114), which is made as a coating at the inner surface section of the light-transmitting unit. The LEDs are mounted and electrically coupled to the conductive laminated structure and divided into at least the first circuit and the second circuit. The conductive laminated structure includes a multitude of electrode paths at the inner surface of the light-transmitting unit, at that the first LED circuit is coupled electrically to the path (118) of the first electrode and the path (120) of the second electrode, and the second LED circuit is coupled electrically to the path (120) of the second electrode and the path (124) of the third electrode.

EFFECT: potential adaption of colour temperature and required light output.
