FIELD: physics.
SUBSTANCE: proposed device comprises waveguide plate and assemblage of point light sources mounted on flexible pcb arranged nearby waveguide plate side surface. Point light source comprises LED device, metal core integrated with the latter and electrode input. Note here that a part of metal core extends on the side on mounting surface. Flexible pcb comprises wiring conductor connected with electrode input of point light source and heat dissipating conductor that matches with point light source and is separated from adjacent heat dissipating conductor to rule out conductance there between. Point light source electrode input and flexible pcb wiring conductor are jointed together by conducting adhesive, as well as point light source metal core and flexible pcb heat dissipating conductor.
EFFECT: higher efficiency of light emission, longer service life.
