FIELD: lighting engineering.
SUBSTANCE: proposed lighting unit has mounting substrate provided with mounting and wiring section and side walls, first and second depressions formed about mounting and wiring section, as well as first and second grooves between mounting and wiring section and first and second depressions. Unit also has first and second tab connectors formed on bottom surface of mounting and wiring section, first and second contact pads formed on bottom surfaces of first and second depressions, first and second conducting strips formed along bottom surfaces of first and second grooves, as well as light-emitting diode installed on mounting and wiring section and connected to first and second tab connectors.
EFFECT: enhanced reliability due to eliminating open circuit in conducting strips.
