A heat sink for a dental light-curing device comprises three mounting surfaces that are each configured for mounting a light source, such as an LED or LED array, which is capable of generating light suitable for curing light-curable compounds. The mounting surfaces are configured with a geometric arrangement in which one of the mounting surfaces is placed nearer to the tip of the heat sink than either of the remaining two mounting surfaces, which are placed adjacent to the first mounting surface and are spaced an equal distance away from the tip of the heat sink. This arrangement generally minimizes the heat that is generated by the LEDs at the tip of the heat sink and expedites the diffusion of heat from the LEDs.

A dental curing light includes a body, one or more LEDs configured to emit a first spectrum of light having a relatively short first peak wavelength (e.g., UV) disposed on the body, and a fluorescing lens that converts at least a portion of the first spectrum of light into a second spectrum of light having a second peak wavelength that is longer than the first peak wavelength. The second spectrum of light is selected so as to match the curing spectrum of a desired light-curable dental composition. In a preferred embodiment, the body comprises an elongate wand having a proximal end and distal end. The LEDs may be disposed at or near the distal end of the elongate wand.

A dental curing device includes an elongate wand housing having proximal and distal ends, a light source disposed at the distal end, electronic circuitry at least partially disposed within the wand housing between the proximal and distal ends, and a heat sink. The light source may comprise one or more LEDs. The heat sink comprises a metallic heat sink portion adjacent to the light source and extending partially through the wand housing, and a polymer-based heat sink portion comprising a thermally conductive polymer-based material adjacent to the metallic heat sink portion. The polymer-based heat sink portion may comprise an epoxy-based resin that at least partially surrounds the electronic circuitry. The polymer-based heat sink portion advantageously extends through a portion of the wand housing designed to be gripped by the user when the dental curing light is in use.

433/029000

A curing light incorporates a plurality of different types of LED light sources that are configured to emit different wavelengths. In one embodiment, the different LED light sources collectively emit a broad and broad spectrum of light that emulates the spectrum of light emitted by a quartz-halogen-tungsten bulb. Accordingly, the curing light may be used to cure camphorquinone initiated products as well as adhesives and other photocurable resins that cure at a wavelength different from the wavelength used to initiate curing of products that contain camphorquinone. The curing light may be configured to allow the different LED light sources to be operated simultaneously or separately as desired. Any number of LED light sources may be utilized by the curing light. In one embodiment, the LED light sources are disposed and arranged at the distal end of the curing light in such a manner that the light can be emitted from the LED light sources in an overlapping manner.

433029000

A dental curing light including a body having a housing, one or more light emitting devices disposed on or within the housing, and a light integrator configured to receive light emitted by the at least one light emitting device. The light integrator includes an outer wall defining a hollow reflective internal chamber, an input port through the wall, and an output port through the wall and spaced apart from the input port. Light is received by the light integrator through the input port and into the diffusely reflective internal chamber such that the received light is reflected in many directions and a plurality of times within the internal chamber before being emitted through the output port. Light exiting the output port of the light integrator is such that the intensity of any given wavelength emitted is substantially equally distributed across the entire footprint of emitted light.

A light meter for detecting two or more different wavelengths of light and methods for determining whether a light source configured to emit light at two or more dominant wavelengths is working properly. The inventive light meter includes a housing, two or more receiving means for receiving light energy emitted by an external light source wherein each receiving means is configured to receive light energy of a desired wavelength, detecting means for detecting and measuring light energy received by the receiving means, and display means for providing a visual indication of the existence and intensity of one or more wavelengths of light energy received by the receiving means.

An LED curing light having controlled spectral output. The LED curing light includes two or more LEDs that emit light at different wavelengths and means for selectively and independently controlling the output of each LED as a function of time so as to independently ramp and/or pulse one or more of the LEDs.
