Abstract

Un módulo emisor de luz planar lateral tiene una placa base rectangular (10) y una pluralidad de diodos emisores de luz (12), y los diodos emisores de luz (12) están diseñados con una disposición y se instalan en ambos lados opuestos de la placa base rectangular (10) respectivamente, para que una superficie de salida de luz (14) opuesta a un área de proyección de luz con una intensidad diferente producida por el mismo diodo emisor de luz tenga una trayectoria óptica con una distancia diferente después de que se proyecte una fuente de luz emitida desde los diodos emisores de luz directamente o reflejada desde una micro-estructura reflectora (101) de la placa base rectangular (10), y se consigue un efecto emisor de luz con una distribución de la intensidad de luz uniforme en la superficie de salida de la luz (14) para reducir el coste de fabricación y mejorar de forma eficaz la eficacia de la emisión de luz.
