A device for curing a photosensitive dental composition curable by way of irradiation with light of predetermined wavelength includes a power supply; and a radiation source coupled to the power supply and powered thereby, the radiation source having a radiation output and including an axial array of light emitting diodes. The light emitting diodes are mounted about an assembly axis defined thereby at a plurality of axial distances from said radiation output of the radiation source and being further characterized in that the plurality of light emitting diodes are directed along a plurality of divergent paths such that a position insensitive optical field is generated for curing the dental composition.

Photocuring device with axial array of light emitting diodes and method of curing

An LED device for irradiating a curable dental composition utilizes a convergent lens with an optical axis and off-axis positioning of the LEDs to focus the radiation emitted front the LEDs and direct it toward hard to reach locations.

Device for curing photosensitive dental compositions with off-axis lens and method of curing

A compact, hand held device for curing photosensitive dental compositions curable by way of irradiation with light of predetermined wavelength includes: a handle configured for gripping by a user; a light emitting diode head assembly secured to the handle including at least one light emitting diode constructed to emit light of the predetermined wavelength in response to an applied operating current, the light emitting diode having a characteristic maximum luminous power output; and a current supply coupled to the light emitting diode adapted for operating the light emitting diode at a luminous power output of at least about 85 percent of its characteristic maximum luminous power output.

Compact device for curing dental compositions and method of curing

A dental composition curing method and device for exposing a dental composition to a beam of radiation emitted by a light-emitting-diode (LED) positioned proximate the composition, LED radiation being more efficient than the conventional use of filtered white light or laser radiation.
