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).LIGHTING DEVICE. The present invention relates to a lighting device (1) comprising: a support body (6) delimited along its own main direction of development (X) by a first leading edge (8) and a first rear edge (9) having an outer surface (11) on which a group of LEDs (12) is mounted and an inner surface (20) defining the inner channel (7) of the support body ( 6) in which the thermal dissipation devices (16) are housed. The illumination device (1) also includes: a reflection body (25) extending around the support body (6) which has a concave shaped section facing the group of LEDs (12); a containment body (2) mounted on the outside of the support body (6) provided with a second front edge (30) aligned with the first front edge (8) of the support body (6); a refractive plate (14) attached to the first front edge (8) and the second front edge (30), defining with the support body (6) and the containment body (2) a sealed chamber (13) ) into which the LED group (12) is mounted. Further, the containment body (2) is provided with a second rear opening (17) and the refraction plate (14) is provided with a second front opening (18), with these openings (17) and (18) aligned with the inner channel (7) of the support body (6) to allow a convective motion air flow through the inner channel (7) of the support body (6).
