FLEXIBLE TUBULAR LIGHT SOURCE WITH EFFECT OF MOVING FLASHES Russian patent published in 2009 - IPC F21S4/00 F21S10/06 

FIELD: lighting.

SUBSTANCE: flexible tubular light source with the effect of moving flashes contains a transparent internal cover layer. Internal cover layer is a ribbon-like element, made in the form of flexible transparent plastic by extrusion-type formation. Ribbon-like element has inside the end-to-end lengthwise hole, two copper conductors, passing lengthwise on the side wall of the ribbon-like element and having the same length as the internal cover layer, open gap made lengthwise along the middle line in the lower part of the side wall of he internal cover layer. The flexible, tubular light source also contains several printed-circuit boards, each printed-circuit board is provided with several light-emitting diodes, corresponding to the number of series-connected limiting resistors and integrated microcircuit for controlling light-emitting diode. Each printed-circuit board is supplied with both ends of the connectors. Printed-circuit boards are connected to each other with cables sequentially, printed-circuit board power cables have a parallel connection with the copper conductors, and the signal cables on the printed-circuit board are connected with the controller sequentially. Printed-circuit boards are placed inside the end-to-end hole of the internal cover layer. Transparent external cover layer contains the internal cover layer and several printed-circuit boards; it also has the same length as the internal layer, and is made from flexible plastic by extrusion-type formation.

EFFECT: creation of a flexible tubular source of light with the functions of digital control of the display, providing regeneration of a signal, cascade connection and transmission of a signal without restrictions by distance.
