Abstract
A UV curing lamp is provided which includes a curved and reflective surface which may be a cold mirror and may redirect incident UV light toward a band-pass filter. The UV light may be reflected by the curved, reflective surface and transmitted through the band-pass filter whereas the IR and visible light may pass through the curved, reflective surface. The UV, IR, and visible light reflected by shutters and direct UV, IR, and visible light from the lamp are separated by the band-pass filter which transmits the UV light and reflects the IR and visible light.
Claims21
A curing lamp comprising:
- a light source;
- a reflective surface positioned behind the light source, wherein the reflective surface is designed to reflect light having wavelengths in a first range so that substantially no reflected light is incident on the light source, and wherein the reflective surface is designed to transmit light having wavelengths in a second range;
- and
- a band-pass filter positioned in the path of at least some of the light which the light source is designed to radiate and positioned in the path of at least some of the light which the reflective surface reflects, wherein the reflective surface is formed of two parts.
