Abstract

patente de invenção: módulo emissor de luz, fonte de luz de superfície, visro de cristal líquido, e dispositivo de iluminação. o propósito da presente invenção é fornecer um módulo emissor de luz capaz de emitir luz de iluminação que tenha um tom de cor próximo a uniforme como um todo. a invenção também fornece uma fonte de luz de superfície que tenha mais módulos emissores de luz, e um visor de cristal líquido e um dispositivo de iluminação que tenha tal fonte de luz de superfície. em um módulo emissor de luz (50), fontes de luz pontuais adjacentes (17,17) satisfazem aos relacionamentos <225>x1 + <225>x2 = <225>x x 2 e <225>y1 + <225>y2 = <225>y x 2, de modo que a cor misturada resultante pode ficar dentro uma área de classificação de cromaticidade (m), e o centro (gc) de uma área de primeira classificação de cromaticidade g e o centro (ec) de uma área de segunda classificação de cromaticidade (e) são axissimétricos com respeito às linhas retas virtuais (ge1, ge2) que passam através dp centro (mc) da área de classificação de cromaticidade alvo (m) e parelelas a um lado ou outro lado da área de classificação de cromaticidade alvo (m).
