  • Publication number: 20140003081
    Abstract: An optical fiber (500) illuminates the bore (520) of a capillary tube (515) that is used for separating chemicals by capillary electrophoresis (CE). The fiber terminates in either two sloped regions (525) and a curved region (530) or two sloped regions (705) and a flat region (700). Light from these regions is focused on the bore of the capillary tube. Since the fiber is sized to illuminate the core of a CE capillary, it is larger than fibers used in telecommunications and its sloped regions are at angles that would be unsuitable for use in telecommunications. The relatively large diameter of the capillary permits efficient use of a light source (905).

  • Patent number: 8545078
    Abstract: A solar lighting apparatus uses optical fibers to transmit solar light for illumination. The apparatus includes a support frame, optical fibers, a hybrid solar light diffuser and a reflective sheet. The optical fibers are fastened to the support frame and are spaced apart from each other at regular intervals. The hybrid solar light diffuser is coupled to a lower portion of the support frame and includes a diffusion plate and diffusion lenses which are provided on the diffusion plate at positions corresponding to the respective optical fibers. Each diffusion lens has a width increasing from a top thereof to a bottom. An incident depression is formed in the upper end of each diffusion lens. A reflective surface is formed on the circumferential outer surface of each diffusion lens to diffuse and reflect solar light. The reflective sheet is applied to the lower surface of the support frame.

  • Publication number: 20130242593
    Abstract: A selective light assembly for a sighting device associated with an archer bow or the like has a plurality of light collectors, such as optical fibers, that serve as sight points. An artificial light source is adapted for projecting radiant energy in a direction toward the light collectors and a base member is operatively associated with the light source. The base member has at least one window adapted for alignment with at least one of the light collectors. At least one of the light source and base member is adjustable between first and second positions, such that the radiant energy projects through the base member and onto first and second light collectors for selectively illuminating a sight dot associated with one of the light collectors.
