Abstract

•A numerical study is made concerning deficient thermal conduction path of LED lamp.•Deficient thermal path affects LED thermal properties even with efficient heat sink.•Junction temperature exceeds 120°C for an air layer thickness ε>150μm.•No indication from the heat sink temperature about the deficient thermal path.•The deficient path effect is more pronounced for lower effective thermal conductivity.
