Abstract

The present invention relates generally to systems for directing light-based radiation onto a light curable material. More particularly, the present invention is directed to a device for uniformly exposing a UV curable material to UV energy.

Claims (15)

1. A device for accommodating a curable material contained in a longitudinal vessel for exposure to radiation in the electromagnetic spectrum, comprising:

an elongate housing having a central bore extending therethrough, said bore defining a curing location for accommodating said longitudinal vessel;

said bore further including at least two aligned longitudinally spaced transversely directed light guide apertures extending into communication with said bore;

whereby said housing directs said radiation injected into said bore from said light guide apertures substantially perimetrically about said vessel along a longitudinal extent thereof.

2. A device of claim 1 wherein said central bore is generally elliptically shaped and wherein said curing location is located at one focus defined by said elliptical shape of said bore.

3. A device of claim 2 wherein said light guide apertures are aligned adjacent the other focus defined by said elliptical shape of said bore.

4. A device of claim 1 wherein said radiation is UV radiation.

5. A system for exposing a curable material contained in a longitudinal vessel to radiation in the electromagnetic spectrum comprising:

a light block having a longitudinal bore therethrough, said bore accommodating said vessel therein;

a pair of spaced apart longitudinally aligned transversely extending light apertures in communication with said bore; and

a pair of light guides supported in said pair of apertures for delivering said radiation into said bore;

wherein said light block directs said radiation to said vessel along a longitudinal extent thereof.

6. A system of claim 5 wherein said longitudinal bore is elliptically shape and wherein said vessel is accommodated at one focal point defined by said elliptical shape.

7. A system of claim 6 wherein said light apertures are aligned adjacent the other focal point defined by said elliptical shape.

8. A system of claim 5 wherein said radiation is UV radiation.
