Title:
LIGHT-EMITTING MODULE, LIGHT SOURCE, AND DENTAL LIGHT-CURING MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/051274
Kind Code:
A1
Abstract:
The present invention relates to the technical field of oral medical instruments. Disclosed are a light-emitting module, a light source, and a dental light-curing machine. On the basis of the arrangement of a plurality of light-emitting units in a rectangular array within a preset rectangular area, the light-emitting units arranged in the rectangular array comprise at least two second light-emitting units (40) within a rectangular central area concentric with the preset rectangular area, and both first light-emitting units (30) and the second light-emitting units (40) within the preset rectangular area are symmetrically distributed around the center point of the preset rectangular area. Therefore, this arrangement allows a first color light emitted by the first light-emitting units (30) and a second color light emitted by the second light-emitting units (40) to blend into a more uniform mixed-color light. When the dental light-curing machine with the light-emitting module is used to radiate light-curing materials, the curing efficiency of a photoinitiator is ensured, thereby ensuring the curing effect of the light-curing materials.
