Abstract
A lighting device includes a light guide plate, a light source circuit, and a chassis. By conducting an extrusion process, the light guide plate may at least include a first light-guiding area and a second light-guiding area. The light source circuit faces toward an inlet of the light guide plate. When the light source circuit emits light beams toward the light guide plate, the first light-guiding area reflects the light beams toward a first light-guiding angle group, and the second light-guiding area reflects the light beams toward a second light-guiding angle group. The first light-guiding angle group is different from the second light-guiding angle group. The chassis is configured to fix the light guide plate and the light source circuit.
