Abstract

DISPOSITIVO DE ILUMINAçãO. A presente invenção refere-se a um dispositivo de iluminação (1), que compreende: um corpo de suporte (6), delimitado ao longo de uma própria direção principal de desenvolvimento (X) por uma primeira borda dianteira (8) e por uma primeira borda traseira (9), dotado de uma superfície externa (11), na qual é montado um grupo de LEDs (12), e de uma superfície interna (20), que define o canal interno (7) do corpo de suporte (6) no qual estão alojados os dispositivos de dissipação térmica (16). O dispositivo de iluminação (1) também inclui: um corpo de reflexão (25), que se desenvolve ao redor do corpo de suporte (6), que tem como geratriz uma secção de forma cóncava virada para o grupo de LEDs (12); um corpo de contenção (2), montado na parte externa do corpo de suporte (6), dotado de uma segunda borda dianteira (30) alinhada à primeira borda dianteira (8) do corpo de suporte (6); uma chapa de refração (14) fixada apoiada à primeira borda dianteira (8) e à segunda borda dianteira (30), definindo, com o corpo de suporte (6) e com o corpo de contenção (2), uma câmara vedada (13), no interior da qual é montado o grupo de LEDs (12). Ainda, o corpo de contenção (2) é dotado de uma segunda abertura traseira (17) e a chapa de refração (14) é dotada de uma segunda abertura dianteira (18), sendo essas aberturas (17) e (18) alinhadas ao canal interno (7) do corpo de suporte (6) para permitir a passagem de um fluxo de ar de movimento convectivo através do canal interno (7) do corpo de suporte (6).
