Abstract

a presente invenção refere-se a um dissipador de calor para dispositivos de led que compreende um corpo laminar condutor de calor com duas faces opostas (11.1, 11.2) e uma superfície perimetral (11.3), em que pelo menos uma das faces (11.1, 11.2) integra uma ou mais pcbs de led (5), e que permite obter uma dissipação de calor mais eficiente do que um dissipador de calor com aletas devido à sua configuração laminar.
