  • Patent number: 5126922
    Abstract: An illuminated umbrella or parasol (1) is described, in which there are two coaxial light conductors (not shown) within the umbrella stick (2). The inner light conductor supplies light to the central region of the cover (3), to a number of further light conductors in the ribs (4) terminated by light-spreading rib caps (11), and to a lightspreading top spike (12), while the outer light conductor supplies light to the peripheral region of the cover (3). Emphasis on the illumination may be switched between the two coaxial light conductors by means of optical means (not shown) in the handle (7), controlled by a manually slideable button (36), said handle (7) also containing the requisite batteries, a light light bulb and a lens and/or a reflector (not shown), the switching e.g. being achieved by altering the position of the bulb.
