A lightweight beam structure includes a first and a second frame. The first frame includes an upper plate, two inner side plates downward bent and extended from two sides of the upper plate, two outer side plates upward bent and extended from two inner side plates respectively and two fixing plates bent and extended from two outer side plates respectively. Each outer side plate is formed outside each inner side plate. A groove is formed between each inner side plate and each outer side plate. The second frame is connected with the first frame and includes a top plate and two intermediate plates downward bent and extended from two sides of the top plate. Each intermediate plate is received in each groove. The top plate is formed over the upper plate. Therefore, the stability is maintained and the weight is reduced so that the material costs may be decreased.

A backlight refraction lens includes a body formed with an incident face and an emergent face, wherein the incident face has a raised periphery and an axis formed with an angle with an axis of the body, the angle, between the axis of the incident face and the axis of the body, set between 35 degrees to 65 degrees such that the ray light going into the body along an incident angle within 15-45 degrees is mostly projected from the emergent face after being refracted. The backlight refraction lens promotes the visibility and identification of objects on the outdoor kanban board when the outdoor kanban board is in a backlight condition such that the conventional LEDs are unnecessary to the outdoor kanban board that has a series of backlight refraction lens in accordance with the present invention mounted thereon.
