Abstract
An illuminating device includes an electronic assembly, a light source, a switch, a housing and a bundle of optical fibers. The electronic assembly is coupled to a power source. The light source is coupled to the electronic assembly to emit light. The switch is coupled to the electronic assembly to activate the power source for controlling an illumination from the light source. The housing has a base and a cover. The base provides a rib guide to secure the light source and an area for holding the electronic assembly. The cover and the base, when coupled together via a coupling post, provide an aperture at one end of the housing. The bundle of optical fibers has a proximal end, a distal end and a longitudinal length. The proximal end is formed by the first ends of the optical fibers. The distal end is formed by the second ends of the optical fibers. The proximal end is securely mounted in a bundle holder disposed through the aperture and positioned at a predetermined focal distance from the light source to allow light from the light source to be transmitted to the distal end along the longitudinal length.
