Abstract

DISPOSITIVO DE LUZ DE POSIçãO TRASEIRA. Trata-se de um dispositivo (1) de luz de posição traseira para aeronaves com uma configuração modular. O dispositivo utiliza fontes de luz de estado sólido. Em uma configuração exemplar, as fontes de luz consistem em diodos emissores de luz (LEDs) de emissão lateral (40), que são acoplados a um dissipador de calor (30) . Um refletor (200) é posicionado adjacente a cada um dos LEDs.O dispositivo inclui adicionalmente uma lente externa (10) com um escudo de recorte (110) integrado e tratamentos óticos (120) . A configuração dos LEDs e refletores, em combinação com o escudo de recorte e os tratamentos óticos, permite que a luz emitida atenda requisitos pré determinados de intensidade angular máxima e mínima. Um módulo eletrónico ( 50) é igualmente acoplado ao dissipador de calor para ligação dos LEDs a uma fonte de alimentação de energia na aeronave. Podem ser realizadas atualizações eletrónicas mediante substituições do módulo eletrónico.
