Abstract
A lamp for more uniformly irradiating surfaces of fibers (including ribbon-shaped fibers), such as optical fibers, and methods of using such lamp, are provided. The lamp has primary and secondary elliptical-shaped reflectors, forming an elliptical space therebetween with the fibers in the vicinity of one focal point of the elliptical space, on the major axis of the elliptical space. The lamp bulb is centered on this major axis of the elliptical space, in the vicinity of the other focal point to provide a dispersed ray pattern at the fiber for more uniformity over the surfaces of the fibers. Ends of the primary reflector can be provided with end reflectors which can have mounts for the lamp bulb. The lamp can be used to cure a light curable coating (e.g., ink, polymer) on the fiber.
