Embodiment Construction

[0075] figure 1 The light guide 10 shown in includes a single-core section 12 and a multi-core section 14 . The two sections 12 and 14 have the same outer diameter and merge into each other in a flush manner at the transition 16 . The single-core segment 12 is positioned adjacent to the light-incident-side end 18 of the photoconductor 10 , and the multi-core segment 14 is positioned adjacent to the light-exit-side end 20 of the photoconductor.

[0076] The single-core section runs in a straight manner and occupies approximately 3 / 4 of the length of the light guide in the illustrated embodiment. The multi-core section 14 is located in the rearmost part of the light guide, ie the front quarter of the light guide, and is bent near the end 20, and in fact is bent at an angle of about 60 degrees.

[0077] The light exit axis 22 correspondingly extends at an angle of approximately 60° to the light entry axis 24 .

[0078] The single-core segment 12 and the multi-core segment 14 i...

Abstract

The invention relates to a radiation source, in particular a light hardening device for the polymerization of dental materials, comprising an optical wave guide and a light generating device which has at least two light sources, preferably semiconductor light sources, in particular light-emitting diodes, and the radiation thereof is directed by a reflector and is coupled into the optical wave guide. Said light sources differ with respect to their light colour and / or their emission spectrum and can be controlled independently from each other for modifying the light colour and / or the emission spectrum and / or the spectral radiation power of the emitted radiation. Said optical wave guide comprises at least one monocore section and a multicore section, the radiation emitted by the light sources being coupled into a monocore section of the optical wave guide. The invention also relates to a light-guiding device for said type of radiation source and / or said type of light hardening device.

Description

technical field [0001] The invention relates to a radiation source, preferably for medical or dental use, in particular to a photocuring device for the polymerization of dental materials according to the preamble of claim 1 , and to a light curing device according to the preamble of claim 15 for This type of radiation source or photoconductor device for photocuring devices. [0002] The term "light" as used herein in the description and claims refers not only to electromagnetic radiation in the visible spectral range, but also to electromagnetic radiation in the UV and near-infrared light range. If reference is made below to preferably used light-emitting diodes (or LEDs or LED chips), these terms are also intended to include other light emitters and radiation sources emitting visible, UV and / or near-infrared light, especially semiconductor radiation sources, But not listed everywhere for better readability. Even though only photocuring devices are sometimes mentioned, the p...
