Abstract
The invention discloses a light guide structure capable of converting point light sources into area light sources and a panel lamp with the light guide structure. The light guide structure is mainly composed of a center light guide plate and a side edge light guide plate. Light guide net points are arranged on the back face of the center light guide plate, the side edge light guide plate is placed on the side face of the center light guide plate, the inner side face of the side edge light guide plate is in contact with the side face of the center light guide plate, and light guide net points are arranged on the outer side face of the side edge light guide plate. A light source is incident from the position between the inner side face and the outer side face of the side edge light guide plate and is incident in the length direction of the side edge light guide plate. After primary light guide of the side edge light guide plate, light evenly shoots into the center light guide plate from the side face, the light evenly shoots out from a light outlet face after secondary light guide of the center light guide plate, the area light sources produced by the light guide structure are evener than that of a traditional light guide plate, with the help of the secondary light guide structure, single high-power light sources can be converted into the area light sources, so that a traditional structure that LED light bars are converted into the area light sources after light guide of the light guide plate is replaced, and a breakthrough is achieved on the development of the panel lamp.
