The chassis includes a box and a partition arranged in the box to define a curing space and a receiving space. The carrier is translucent and is arranged in the curing space. The driving mechanism is connected to the carrier to rotate the carrier. The bottom light curing module is arranged in the receiving space and includes a plurality of light curing units. The light curing units of the bottom light curing module are configured to emit a curing light onto at least 80% of the carrier, when the driving mechanism drives the carrier to rotate. ## Claims ### Claim 1 A light curing apparatus, comprising: a chassis including a box and a partition arranged in the box, wherein the partition is configured to divide a space surroundingly defined by the box into a curing space and a receiving space;
