Abstract

"LUMINáRIA GUIA DE LUZ, E, LâMPADA DE SINALIZAçãO PARA UM VEìCULO AUTOMOTIVO". é descrita uma luminária guia de luz, que é capaz de prover um feixe de luz substancialmente monocromática e é adequada para uso como uma lâmpada de sinalização em um veículo automotivo. A luminária (1) compreende um alojamento definindo uma cavidade óptica guia de luz (4), tendo primeira e segunda faces maiores (5, 6) e uma fonte de luz (11) disposta para dirigir luz para dentro da cavidade por um lado. A fonte de luz pode ser uma formação de diodos emissores de luz, provendo luz substancialmente monocromática. A primeira face maior (5) compreende uma película de interferência (por exemplo, uma película polimérica de multicamadas) que, para luz no comprimento de onda do projeto, transmite substancialmente luz que é incidente sobre a película através de uma faixa angular limitada e substancialmente reflete luz que é incidente em outros ângulos. A segunda face maior (6) compreende um material reflexivo dispersante, tendo uma refletância de pelo menos 85%, por exemplo, um material reflexivo altamente eficiente, provido com um padrão texturizado adequado.
