The present disclosure discloses a panel light and a panel light apparatus. The panel light comprises a light guide plate module, a light-transmitting shell, and a light source module. The light guide plate module comprises at least two light guide plates spaced apart from each other, a light guide gap is formed between two adjacent light guide plates, and the light guide plates each comprise a light incident surface and a light exit surface. The light-transmitting shell is provided with an accommodating cavity, and the light guide plate module is arranged in the accommodating cavity. The light-transmitting shell comprises a light guide panel and at least one first light guide side edge. The light guide panel covers the light incident surface of the light guide plate module, and the first light guide side edge is arranged on a side of the light guide panel facing toward the accommodating cavity and is located in the light guide gap, which side faces toward the accommodating cavity. The light source module comprises a first light source and a second light source. The first light source is arranged opposite to the light incident surface of the light guide plate. The light emitted by the first light source enters the interior of the light guide plate through the light incident surface and exits through the light exit surface and the light guide panel. The light from the second light source exits through the first light guide side edge. The above-mentioned panel light has relatively rich lighting effects.

A method for constructing a lamp chain circling model comprises: obtaining an on-site image of a lamp chain that spirally circles around an external carrier, determining a planar spatial position of each front lamp bead of the lamp chain in an image view space, and determining a conical model of the external carrier; unfolding the conical model into a sector-shaped reference region in the image view space; arranging each circle of rear lamp beads on the surface of the sector-shaped reference region according the missing number of each circle of rear lamp beads on the lamp chain, and determining sector-shaped spatial positions of all the lamp beads in the sector-shaped reference region; mapping the sector-shaped spatial positions of the lamp beads on the surface of the sector-shaped reference region to corresponding stereoscopic spatial positions in a modeling space, and obtaining the lamp chain circling model.
