Abstract

fonte de luz de plasma acionada por microondas. um cadinho luzente de uma fonte de luz de plasma de microonda com guia de onda luzente (lwmpls) compreendendo um ressonador de emissão de luz (ler) na forma de um cadinho (1) de quartzo fundido que tem um espaço vazio central (2) tendo material excitável por microondas (3) no mesmo. em um exemplo, o espaço vazio tem 4 mm de diâmetro e tem um comprimento (l) de 21 mm. a lwmpls é operada em uma potência (p) de 280 w e desse modo com uma carga de plasma p/l de 133 w/cm e uma carga de parede de 106 w/cm2. a lâmpada é desse modo operada com uma eficiência elevada - em termos de lumens por wat - enquanto tem um tempo de vida razoável.
