Abstract

A polymerization apparatus according to an embodiment of the present invention includes: a light irradiator; and a polymerization vessel. The light irradiator includes a first casing and a light source assembly. The first casing includes a light source chamber defined by cylindrical side walls, a ceiling, and a floor including a light-transmissive window member. The light source assembly includes a base having a light-emitting surface on which a plurality of light-emitting diodes is disposed in a predetermined pattern and a heat-dissipating surface to which a heat sink is joined, and the light source assembly is disposed within the light source chamber so that the light-emitting surface faces the light-transmissive window member. The polymerization vessel includes a polymerization cup and a second casing. The polymerization cup has a frustoconical or substantially frustoconical shape that opens upward and increases in diameter upward, and is capable of housing an object therein. The second casing is a bottomed cylindrical or box-shaped casing having an opening at the apex thereof, the polymerization cup being attachably/detachably housed in the second casing via the opening. In this polymerization apparatus, light that has been emitted by the plurality of light-emitting diodes of the light irradiator and has passed through the light-transmissive window member is applied to the inside of the polymerization cup of the polymerization vessel.
