摘要: A lighting apparatus includes a first light source, a second light source, a first light guide plate, a second light guide plate and a driver. The first light source emits a first light. The second light source emits a second light. The first light guide plate receives the first light from a first lateral wall and guides the first light to escape via a first surface of the first light guide plate. The second light guide plate receives the second light and guides the second light to escape via a second surface of the second light guide plate. The second surface has an image pattern. The image pattern is rendered by placing multiple first light escaping dots on the second surface. The multiple first light escaping dots are divided into multiple sets for rendering multiple visual objects by arranging area intensities of the first light escaping dots.
