US 2019/0239994 A1 · WHITE LIGHT CONVERTERS

Abstract

An optical converter assembly includes a housing, a securing mechanism, and a light converter. The housing defines a first opening that receives part of a light-emitting portion of a dental curing light when the housing is selectively secured relative to the light-emitting portion of the dental curing light. The securing mechanism selectively retains the housing relative to the light-emitting portion. The light converter is comprised of a phosphor material and secured relative to the housing such that input light having a first set of wavelengths and radiant power emitted by the dental curing light is received. The light converter converts the input light to an output light having a second set of wavelengths and radiant power and to emit the output light. The input light includes a blue light and an ultraviolet light that polymerizes a dental material. The output light may be a white light.

Dependent claims

An optical converter assembly comprising:

a housing that defines a first opening at a first end, the first opening being configured for receipt of a portion of a light-emitting portion of a dental curing light when the housing is selectively secured relative to the light-emitting portion of the dental curing light;
a securing mechanism that is configured to selectively retain the housing relative to the light-emitting portion;
and
a light converter comprising a phosphor material, the light converter being secured relative to the housing such that an input light having a first set of wavelengths and a first radiant power emitted by the dental curing light is received by the light converter, wherein the light converter is configured to convert the input light to an output light having a second set of wavelengths and a second radiant power and to emit the output light that is substantially a white light.

An optical converter assembly that is selectively secured relative to a dental curing light, the optical converter assembly comprising:

a housing that defines an internal volume between a first opening at a first end and a second opening at a second end, the first opening and a first portion of the internal volume being configured for receipt of a portion of a light-emitting portion of a curing light such that a curing light of the dental curing light is aligned with the first opening and the second opening;
a magnetic element that is positioned within the internal volume of the housing, wherein the magnetic element is configured for magnetic retention of the housing relative to the curing light of the dental curing light;
and
a light converter that is positioned in the internal volume between the first opening and the second opening such that input light emitted from the curing light enters the internal volume and is received by the light converter,
wherein the light converter is constructed of a phosphors matrix including a plurality of phosphor particles that in response to receipt of the input light, emits an output light via luminescence that is a white light.
